The Last Page? The Enduring Fight for Printed Books and the Bookseller’s Struggle

In an age of glowing screens and instant digital downloads, the printed book feels almost like an artifact. Yet, it endures—a testament to its tactile pleasure, the scent of its pages, and the timeless ritual of turning them. While digital formats offer convenience, the printed book remains a powerful cultural symbol. For the bookseller, however, this coexistence has created a new set of challenges, transforming their role from mere merchants of books to custodians of a culture, fighting for survival in an increasingly digital world.

The Rise of the Digital Realm: A New Challenger
The past two decades have seen a seismic shift in the publishing landscape, driven by two primary forces:

E-books and Digital Readers:

The advent of devices like the Kindle and Kobo made it possible to carry thousands of titles in one’s pocket. For readers who prioritize convenience, storage, and cost, e-books offer a compelling alternative.

Online Retail Giants:

books-online
books-online

The sheer scale and speed of online behemoths like Amazon have disrupted traditional retail. They offer a vast catalogue, often at discounted prices, delivered straight to the customer’s doorstep, bypassing the physical bookstore entirely.

This dual assault has left the traditional bookseller on the frontlines of a battle for relevance.

The Bookseller’s Battle: Challenges on Every Shelf
The modern bookseller faces a formidable array of challenges that go far beyond just selling books:

Shrinking Margins: The deep discounts offered by online retailers force physical bookstores to compete on price, a losing battle. This erodes their already slim profit margins, making it difficult to cover overheads like rent and staff salaries.

The “Showrooming” Problem: Customers frequently visit bookstores to browse, discover new titles, and get recommendations from staff, only to then purchase the book online for a lower price. The physical store becomes a free showroom for online competitors.

Inventory Management: Deciding what titles to stock is a delicate art. A small bookstore can’t possibly compete with the endless digital catalogue. They must curate a collection that is both commercially viable and reflective of their community’s interests—a constant guessing game.

High Overheads: Brick-and-mortar stores come with significant costs: rent, electricity, maintenance, and staff wages. These fixed costs are a heavy burden, especially with fluctuating foot traffic.

The “Experience” Paradox: While physical bookstores are valued for the browsing experience, community feel, and expert recommendations, translating this intangible value into sales is a constant struggle. The very thing that makes them unique isn’t enough to guarantee profitability.

The Fight for Survival: From Bookstore to Cultural Hub
The booksellers who are thriving today have realized that they can’t simply be a place to buy books. They must become something more—a vital cultural hub in their community. Their strategy is a masterclass in adapting to the digital age:

Curated Collections: Rather than trying to stock everything, they specialize. They might focus on local authors, a specific genre (like sci-fi or history), or independent publishers, creating a unique identity that online retailers can’t replicate.

Community Events: Bookstores are becoming venues for author readings, book clubs, poetry slams, children’s story hours, and workshops. These events foster a sense of community and provide a reason for people to step away from their screens and gather.

Expert Recommendations: The biggest advantage a physical bookstore has is its knowledgeable staff. They offer personalized recommendations and a human touch that no algorithm can match.

Partnerships: Collaborating with local cafes, schools, and literary festivals to host events and cross-promote. A bookstore can become a linchpin of the local cultural ecosystem.

Diversification: Many bookstores now sell coffee, stationery, unique gifts, and other merchandise to supplement their income and create a more compelling retail experience.

Conclusion

The printed book is not dead, but it has changed. It is no longer just a vessel for information; it is an object of value, an aesthetic choice, and a symbol of a more mindful way of consuming knowledge. The bookseller is its guardian, a passionate advocate in a world of instant gratification. Their fight for survival is more than a commercial battle; it is a cultural one. By transforming their stores into vibrant community spaces, they are proving that in the digital age, a place where people can gather, browse, and connect over a shared love of reading is more essential than ever. The last page has yet to be turned.

Insect Killers in Agriculture: Protecting Crops for Better Yields

Agriculture has always been the backbone of human civilization. Farmers work tirelessly to grow food for the world, but one of their biggest challenges is protecting crops from harmful pests and insects. Insects such as caterpillars, beetles, aphids, and borers can quickly damage plants, reduce crop yield, and affect overall quality. To tackle this problem, insect killers in agriculture play a vital role. These solutions not only help safeguard crops but also ensure that farmers can achieve better productivity and profitability.

Why Are Insect Killers Important in Farming?

Crops are vulnerable to different pests at various stages of growth. Some insects chew on leaves and stems, while others attack roots or suck plant sap. If not controlled in time, they can cause heavy losses. For example, locusts can destroy acres of farmland within hours, while tiny insects like whiteflies spread plant diseases.

Insect killers provide an effective shield against these threats. By using them properly, farmers can:

  • Prevent crop damage: Protect leaves, flowers, and fruits from being eaten or destroyed.
  • Improve yield: Healthy crops produce more harvest, increasing farmers’ income.
  • Ensure food security: By saving crops, insect killers help in maintaining a stable food supply.
  • Reduce spread of diseases: Many insects act as carriers of plant diseases, so controlling them reduces overall risk.

Types of Insect Killers Used in Agriculture

Insect control methods have evolved over time. Today, farmers use a combination of traditional and modern techniques. The major types include:

Chemical Insecticides

These are the most widely used insect killers in farming. They come in different forms such as sprays, powders, or granules. Chemical insecticides act quickly and can control a wide range of pests. However, excessive or careless use can harm the environment, beneficial insects, and even human health. That’s why farmers are encouraged to use them in limited, recommended quantities.

Biological Control

This method involves using natural predators or parasites to kill harmful insects. For example, ladybugs feed on aphids, and certain wasps attack caterpillars. Biological control is eco-friendly and does not leave harmful residues on crops. Many agricultural scientists recommend combining biological control with other methods for sustainable farming.

Organic and Botanical Insect Killers

These are made from natural plant extracts such as neem oil, garlic, or pyrethrum. Organic insect killers are safe for crops, soil, and consumers. They are gaining popularity among farmers who follow organic farming practices. Although they may act slower than chemical insecticides, they are considered healthier and more sustainable in the long run.

Mechanical and Physical Methods

Sometimes farmers use insect traps, sticky sheets, or light-based devices to capture and kill insects. This method is cost-effective and especially useful in greenhouses or small-scale farms.

Integrated Pest Management (IPM)

IPM is a modern approach that combines different methods—chemical, biological, mechanical, and organic—based on the situation. The goal is to reduce dependency on harmful chemicals while keeping pests under control. IPM is widely promoted as a sustainable solution for modern agriculture.

Best Practices for Using Insect Killers

While insect killers are essential, their improper use can cause more harm than good. Here are some best practices:

  1. Identify the pest correctly – Different insects require different control methods.
  2. Use recommended doses – Overuse of chemicals can damage soil fertility and harm beneficial insects.
  3. Follow safety measures – Farmers should wear protective gear when applying insecticides.
  4. Adopt eco-friendly solutions – Wherever possible, choose organic or biological methods.
  5. Rotate insecticides – Using the same chemical repeatedly can lead to pest resistance.

The Future of Insect Killers in Agriculture

With growing awareness about food safety and environmental health, the future of insect killers lies in eco-friendly innovations. Scientists are developing bio-pesticides, genetically resistant crops, and smart devices that can monitor and control insect populations automatically. These advancements aim to reduce harmful impacts while ensuring strong protection for crops.

Conclusion

Insect killers in agriculture are an essential tool for farmers to protect their hard work and ensure healthy harvests. From traditional chemical sprays to modern organic and biological solutions, these tools provide different options for every farming need. However, the key is to use them responsibly and sustainably. By adopting smart practices and combining multiple methods, farmers can achieve higher yields, protect the environment, and contribute to global food security.

Nanoparticles in Tumor Microenvironment Remodeling and Cancer Immunotherapy 2025

Emerging Opportunities and Challenges

Abstract

The tumor microenvironment (TME) profoundly influences cancer progression and often underlies resistance to treatment. Recently, nanoparticles have emerged as versatile tools capable of reshaping this environment to improve the outcomes of cancer immunotherapy. This review delves into the diverse nanoparticle platforms being explored, their underlying mechanisms, and their promise in clinical applications. We also address the challenges faced in this field and consider future directions that might accelerate the translation of these technologies into patient care.

Introduction

Immunotherapy has transformed the landscape of cancer treatment by harnessing the immune system to fight tumors. Yet, the immunosuppressive nature of the tumor microenvironment frequently hampers its effectiveness. The TME is a complex and dynamic milieu comprising cancer cells, supportive stromal cells, immune suppressor populations, and extracellular matrix components. Together, these elements create a barrier that limits immune cell infiltration and function. Nanotechnology offers novel strategies for overcoming these hurdles by deploying engineered nanoparticles that can deliver immune-modulating agents and reprogram the local immune contexture, thereby enhancing therapeutic efficacy.

Overview of the Tumor Microenvironment

At its core, the TME is a diverse ecosystem where tumor cells interact with stromal cells, immune cells, blood vessels, and extracellular matrix. This network not only fosters tumor growth and metastasis but also actively suppresses anti-tumor immunity. Central to this immunosuppressive landscape are cell types such as tumor-associated macrophages (TAMs), myeloid-derived suppressor cells (MDSCs), and regulatory T cells (Tregs), which blunt immune responses and pose significant challenges for immunotherapy.

Immunotherapy

Nanoparticles as Modulators of the TME

Nanoparticles have shown considerable promise in reshaping the TME through various mechanisms:

  • Inhibiting Fibroblast Activation: By targeting cancer-associated fibroblasts, nanoparticles can soften the dense extracellular matrix, which otherwise acts as a physical barrier preventing immune cell entry.
  • Reprogramming Macrophages: These particles can shift macrophages from a pro-tumor M2 state to an anti-tumor M1 phenotype, fostering a more hostile environment for the tumor.
  • Enhancing Dendritic Cell Function: Nanoparticles promote dendritic cell maturation and antigen presentation, which is crucial for activating effective T cell responses.
  • Encouraging T Cell Infiltration: Remodeling of the TME by nanoparticles facilitates the movement of cytotoxic T lymphocytes into tumor sites.

Types of Nanoparticles and Their Applications

Several nanoparticle platforms have been developed, each with unique advantages:

  • Biomimetic Nanoparticles: These are designed to resemble natural biological structures, improving their uptake by immune cells and enhancing targeting precision.
  • Exosomes: Naturally secreted vesicles that can be engineered to deliver immunomodulatory cargo, influencing immune cells within the TME.
  • Stimuli-Responsive Nanocarriers: These smart carriers release their therapeutic payloads selectively in response to tumor-specific signals such as pH changes or oxidative stress, minimizing side effects.

Other platforms include liposomes, polymeric nanoparticles, and inorganic nanoparticles, all contributing to a toolkit tailored for various therapeutic goals.

Mechanisms of Action

Nanoparticles aid cancer immunotherapy through:

  • Targeted Delivery: Concentrating immunostimulatory agents at the tumor site reduces systemic exposure and toxicity.
  • Induction of Immunogenic Cell Death: This process exposes tumor antigens and danger signals, enhancing immune recognition.
  • Boosting Antigen Presentation: By improving dendritic cell activity, nanoparticles amplify T cell responses.
  • Modulating Suppressive Immune Cells: Altering populations like TAMs and Tregs restores immune surveillance capabilities.

Immunotherapy Strategies Involving Nanoparticles

Nanoparticles increasingly complement existing immunotherapies:

  • Synergy with Checkpoint Inhibitors: By modifying the TME, nanoparticles can amplify the effects of checkpoint blockade
  • Cancer Vaccines: They improve the stability and immune activation potential of vaccines.
  • Adoptive Cell Therapy Support: Nanoparticles can enhance CAR-T or NK cell therapies by delivering supportive factors or altering the tumor niche.
  • Personalized Treatments: Tailoring nanoparticles to individual tumor characteristics could maximize therapeutic benefit.

Challenges and Limitations

Despite progress, several hurdles remain:

  • Achieving Targeting Specificity: The heterogeneity of tumors and dense stroma complicate delivery.
  • Safety Concerns: Long-term effects and potential toxicity require comprehensive evaluation.
  • Regulatory and Manufacturing Barriers: Standardizing production and navigating approvals are non-trivial tasks.
  • Tumor Adaptability: The evolving nature of tumors demands flexible, adaptable nanoparticle strategies.

Future Perspectives

The future lies in multifunctional, “smart” nanoparticles capable of precise modulation of the TME. Integrating AI and computational modeling may refine nanoparticle design for personalized medicine. Combining these platforms with novel immunotherapies holds promise for more durable and effective cancer treatments. Rigorous clinical trials will be critical to bringing these innovations from bench to bedside.

Conclusion

Nanoparticles provide a compelling avenue to overcome the immunosuppressive hurdles of the tumor microenvironment, enhancing the potential of immunotherapy. Continued multidisciplinary efforts will be vital to address existing challenges and translate these promising technologies into clinical realities.

Paradox and Quantum Mechanics: When Reality Plays by Strange Rules

Human curiosity has always been driven by a desire to understand the universe in simple, logical terms. Yet, sometimes nature answers our questions with a riddle, a contradiction, or what scientists call a paradox. Paradoxes are situations that defy intuition or challenge the way we think reality should behave. They can be thought of as intellectual knots—puzzles that seem to say, “Wait… how can that be true?”

When we step into the world of quantum mechanics—the branch of physics that studies the smallest particles in existence—paradoxes don’t just appear occasionally; they seem to be everywhere. The deeper we look, the more we realize that the universe doesn’t always play by the rules we thought we knew.

What Is a Paradox?

A paradox occurs when two apparently contradictory ideas or facts both seem true at the same time. Some paradoxes are just misunderstandings of language or logic. Others, especially in science, are genuine phenomena where reality behaves in ways that challenge our understanding.

For example:

  • In the grandfather paradox, if you travel back in time and prevent your grandfather from meeting your grandmother, you wouldn’t be born—but if you were never born, how could you travel back to stop them from meeting?
  • In the liar paradox, the statement “This sentence is false” can’t be consistently labeled as true or false.

While these are thought experiments, quantum mechanics introduces real-life situations where paradox-like behavior is measurable and repeatable.

Quantum Mechanics: The Playground of Paradox

quantum mechanics
quantum mechanics

Quantum mechanics deals with the behavior of particles like electrons, photons, and atoms. These particles exist at scales so small that the classical laws of physics—like Newton’s laws—stop working in a predictable way.

Instead, particles in the quantum realm seem to obey strange rules:

  • They can exist in multiple states at the same time (superposition).
  • They can be linked across space instantly (entanglement).
  • They don’t seem to have definite properties until measured (wavefunction collapse).

These behaviors often sound like science fiction, but they’ve been confirmed repeatedly by experiments. The challenge is that they don’t match how we experience the everyday world, which is why so many paradoxes arise.

Famous Quantum Paradoxes

  1. Schrödinger’s Cat

Proposed by physicist Erwin Schrödinger in 1935, this thought experiment involves a cat in a sealed box with a quantum trigger that has a 50% chance of killing it. Quantum theory says that until we open the box and observe the cat, it’s both alive and dead—a superposition of states. This is not a literal suggestion about cats, but a way to highlight the weirdness of applying quantum rules to larger objects.

2. The EPR Paradox

In 1935, Einstein, Podolsky, and Rosen proposed a paradox to challenge quantum mechanics. They argued that if two particles are entangled and separated by vast distances, a measurement on one instantly affects the other—implying “spooky action at a distance.” Einstein thought this meant quantum theory was incomplete. Later experiments confirmed that entanglement is real and instantaneous, even if it defies classical logic.

3. The Quantum Zeno Effect

This paradox says that a quantum system’s evolution can be “frozen” by constantly observing it. In other words, the act of measurement can stop change from happening—something that sounds impossible but has been observed experimentally.

Why Do Quantum Paradoxes Matter?

These paradoxes are more than brain teasers. They are clues that our everyday assumptions about reality may be incomplete. In fact, quantum mechanics has given rise to revolutionary technologies:

  • Quantum computers that can solve problems classical computers can’t.
  • Quantum cryptography for ultra-secure communication.
  • Quantum sensors with precision far beyond current limits.

By wrestling with paradoxes, scientists often discover deeper truths about the universe.

Philosophical Implications

Quantum paradoxes force us to ask fundamental questions:

  • Is reality objective, or does it depend on observation?
  • Do particles exist in a definite state before we look?
  • Is the universe deterministic, or does chance play a fundamental role?

These questions blur the line between physics and philosophy, showing that understanding the universe isn’t just about equations—it’s about rethinking what “reality” means.

Conclusion

Paradoxes in quantum mechanics remind us that nature is under no obligation to conform to human intuition. The universe operates according to its own principles, even if they seem contradictory or strange to us. By exploring these paradoxes, scientists aren’t just solving puzzles—they’re peeling back layers of reality itself.

Quantum mechanics may be full of mystery, but it’s through grappling with these mysteries that we expand the boundaries of human knowledge. And perhaps, in the process, we’ll come to see that the universe’s most puzzling paradox is not how strange it is—but how perfectly it works.

Voyager 1: Humanity’s Far-Flung Messenger to the Stars 2025

On a quiet September morning in 1977, from a launchpad in Florida, a small spacecraft rose into the sky. It wasn’t flashy. It wasn’t carrying humans. But Voyager 1 was about to embark on a journey no other human creation had ever attempted — to leave the warmth of the Sun and venture into the dark ocean of interstellar space.

Forty-seven years later, Voyager 1 is still out there, still talking to us across billions of kilometers, still carrying humanity’s “hello” to the stars.

A Rare Window Opens

Voyager 1 was part of NASA’s daring Voyager program, along with its twin, Voyager 2. Their mission? Use a once-in-a-lifetime alignment of the outer planets to leapfrog across the solar system using gravity as a slingshot. This cosmic opportunity only comes once every 176 years. Miss it, and the chance is gone for generations.

While Voyager 2 set off first, Voyager 1 launched a few weeks later — but on a faster, more direct path toward Jupiter and Saturn. Its job: capture images, study moons, and reveal secrets of planets humanity had only seen as distant points of light.

Meeting the Giants

In March 1979, Voyager 1 reached Jupiter, and what it sent back left scientists breathless. The swirling storms were larger than Earth itself. The Great Red Spot raged like a cosmic hurricane that had been churning for centuries. Then came the shock: Io, one of Jupiter’s moons, was erupting with volcanoes — the most volcanically active world ever found.

Barely a year later, Voyager 1 arrived at Saturn. The spacecraft’s cameras revealed rings so intricate and delicate they looked like spun glass. It discovered new moons, like Atlas and Prometheus, and took a close look at Titan, Saturn’s largest moon. Titan’s thick orange haze hinted at chemistry not unlike the early Earth’s — maybe even the ingredients for life.

Turning Toward Forever

After Saturn, Voyager 1’s path bent upward, out of the solar system’s planetary plane. That meant no visits to Uranus or Neptune — but it also meant something else: a chance to head straight for the edge of the Sun’s influence.

NASA extended the mission. Voyager 1 would now become an interstellar scout, traveling beyond the planets, into the deep frontier where the Sun’s power fades and the galaxy begins.

The Moment We Crossed Over

For decades, Voyager 1 drifted farther, measuring magnetic fields, cosmic rays, and solar wind. Then, in August 2012, it happened: the spacecraft crossed the heliopause — the invisible bubble where the Sun’s solar wind meets the interstellar medium.

It was official: Voyager 1 had stepped into interstellar space. Humanity had left home.

A Golden Handshake to the Cosmos

interstellar
interstellar

Voyager 1 isn’t just a robot carrying sensors. Bolted to its side is something deeply human: the Golden Record.

This gold-plated copper disc holds 115 images, greetings in 55 languages, music from around the world, and the sounds of Earth — waves crashing, birds singing, a baby crying. It’s a time capsule, a message to any life form that might find it.

Carl Sagan, who helped design the record, called it “a bottle cast into the cosmic ocean.” It’s humanity saying, “This is who we are. We were here.”

The Challenges of Talking Across the Void

Voyager 1 is now so far away that a signal traveling at the speed of light takes over 22 hours to reach it — and another 22 hours for a reply to come back. Its power source, a radioisotope generator, loses a little strength every year. NASA engineers carefully shut down instruments to save power, trying to keep it alive as long as possible.

Sometimes, Voyager 1 sends back garbled messages — the cosmic equivalent of a bad phone connection. Yet each time, the team finds a way to fix it. It’s like maintaining a 1970s computer in the middle of nowhere — and nowhere is 15 billion miles away.

Sailing Into the Unknown

By around 2030, Voyager 1 will go silent. Its instruments will power down. No more data, no more updates. And yet, it will keep drifting for billions of years — a silent ambassador, carrying our message long after we’re gone.

In about 40,000 years, it will pass near another star, Gliese 445. Whether anyone is there to receive it… well, that’s a mystery.

Why Voyager 1’s Story Matters

Voyager 1 isn’t just a spacecraft. It’s a symbol of what humans can do when we look beyond our immediate needs and dare to dream big.

It reminds us that exploration isn’t always about the next discovery — sometimes, it’s about sending something into the dark simply because we can, and because we hope someone, someday, might find it.

In the vastness of space, our little golden-eyed traveler sails on, carrying whispers of oceans, laughter, music, and greetings from a small blue planet orbiting a distant star.

And maybe, just maybe, someone out there will one day press “play.”

Effect of Our Emotions on Gut Microbiota 2025

Abstract

Latest researches in neuroscience and Gut microbiota have uncovered a fascinating connection between our emotions, the hormones in our bodies, and the bacteria living in our guts. This review is an effort to gather scientific explanations on  how our feelings can actually affect the composition of gut microbiota through neurohormones.

Introduction

The human gut gives shalter to trillions of colonies of microorganisms, collectively termed the gut microbiota, which executes essential roles in digestion, metabolism, and immune function. Emerging evidence reveals that emotional experiences—such as stress, anxiety, and positive affect—modulate the composition and function of gut microbiota. Central to this modulation is neurohormonal signaling along the gut-brain axis.

The Gut-Brain Axis: Bidirectional Communication

The gut-brain axis is a two directional communication network integrating the central nervous system (CNS), the enteric nervous system (ENS), the hypothalamic-pituitary-adrenal (HPA) axis, and the gut microbiota. Our feelings and thoughts really do affect how our stomach works and even the types of bacteria living inside our gut. This connection happens through various systems in our body – like the nerves, hormones and also the immune system response. So basically, when we’re in a certain mood or overthinking things, it can actually mess with what’s happening in our gut.

  • Endocrine signaling: Neurohormones released in response to emotions, including cortisol, norepinephrine, and serotonin, influence the gut environment.
  • Immune mechanisms: Stress and emotion-induced immune changes can impact gut permeability and microbial communities

Emotional States and Neurohormonal Signaling Stress and Negative Emotions

Emotional stress triggers activation of the HPA axis, resulting in increased secretion of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and ultimately cortisol. These stress hormones have widespread effects on gut barrier function, immunity, and microbial homeostasis.

  • Acute and chronic stress can induce rapid shifts in gut microbial composition in both mucosal and luminal compartments[5]. Specific studies in animal models show increased gut permeability, inflammation, and overgrowth of pathogenic bacteria under stress conditions.
  • Neurohormones such as norepinephrine and cortisol directly modulate bacterial growth and virulence. In vitro, catecholamines can significantly increase certain bacterial populations and enhance their pathogenicity.

Positive Emotions

Positive emotions correlate with distinct gut microbiome profiles. Individuals exhibiting positive affect and emotion regulation have lower abundance of inflammation-associated bacteria and higher levels of beneficial taxa. Specific metabolic pathways related to energy, coenzyme A, and neurotransmitter synthesis also differ with emotional states.

Emotion Regulation

Cognitive strategies that regulate emotion—such as reappraisal or suppression—can alter neurohormonal output, indirectly shaping the gut microbial community.

Neurohormones as Mediators

Neurohormones serve as crucial mediators between emotions and gut microbiota. They are produced both by host tissues (e.g., adrenal glands, enteric neurons) and in some cases by gut microbes themselves.

Important Neurohormones

  • Serotonin: Over 90% of the body’s serotonin is synthesized in the gut, with production regulated by both the microbiota and host cells. Changes in serotonin levels affect gut motility and mood.
  • Dopamine: Some gut bacteria (e.g., Bacillus, Serratia) produce dopamine, influencing both gut and brain signals.
  • GABA, norepinephrine, acetylcholine: Microbes modulate and respond to these neurotransmitters, thereby mediating stress-related effects on gut ecology.

The Impact of Emotional Disorders

Several mental and emotional disorders—including anxiety, depression, and chronic stress—have been linked to gut dysbiosis[10][5]. Shifts in bacterial taxa, decreased diversity, and increased inflammation are often observed in affected individuals. Novel interventions using probiotics and psychobiotics are being explored to restore microbial balance and alleviate emotional symptoms.

Mechanistic Insights

  • Barrier Function: Stress and negative emotions compromise intestinal and blood-brain barriers, facilitating bacterial translocation and contributing to systemic inflammation.
  • Microbial Metabolism: Emotional states alter microbial metabolism, impacting energy, vitamin, and neurotransmitter synthesis pathways in the gut.
  • Immune Interactions: Emotional distress promotes immune activation in the gut, further shaping the microbiota and increasing risk of gastrointestinal pathology.

Table: Emotions, Neurohormones, and Gut Microbiota Interactions

Neurohormones
table

Conclusion

Human emotions exert significant effects on gut microbiota through neurohormonal signaling along the gut-brain axis. Stress and negative feelings typically induce dysbiosis, while positive emotional states and effective emotion regulation appear to support a healthier gut microbial landscape. Continued research in this area may hold promise for innovative therapies targeting the microbiome to promote both mental and physical well-being.

Embryo

Artificial Intelliegnce in Embryo Selection 2025

Abstract

Assisted Reproduction Technology (ART) offers an important solution for infertility, but its success rate is limited to around 30–40% at present. A key factor in ART success is accurately selecting viable embryos, a process traditionally based on manual morphological assessment, morphokinetics, and invasive testing methods that are subjective and variable. Artificial intelligence (AI) has become a transformative tool to improve embryo selection by providing objective, reproducible, and non-invasive options. Recent AI models such as Life Whisperer and iDAScore v1.0 utilize convolutional neural networks (CNNs), time-lapse imaging, and deep learning to predict embryo viability with high accuracy. Studies have shown successful embryo ranking and segmentation, with some models also integrating molecular and genetic data to assess embryo competence and euploidy. Techniques like federated learning and generative models like StyleGAN increase training datasets by expanding them. EVATOM employs AI to classify embryo health. These approaches improve consistency across IVF clinics, reduce human bias, and enhance clinical outcomes. This review provides an overview of how AI-driven embryo selection has the potential to increase ART success rates and lessen the physical, emotional, and financial burdens associated with infertility treatments.

Introduction

While Assisted Reproduction Technology promises to be an alternative for conceiving in case of infertility, the success is still limited to 30-40% in a single cycle in the current age (Gnoth et al., 2011). Globally, 12.6-17.5% couples are affected by infertitilty, making ART a crucial intervention. A deciding factor of the success of the technique lies in the step of healthy embryo selection (Njagi et al., 2023). Traditional approach to selecting embryos involves visual assessment by embryos which involves grading the morphology, morphokinetics study (Meseguer et al., 2011; Motato et al., 2016), pre-implantation genetic testing for aneuploidy (PGTA) (Chen et al., 2025) and metabolic profiling. However, manual selection is subjected to variability among observers and has limited predictive power (Charles L. Bormann et al., 2020).

Embryo selection

The advent of Artificial Intelligence-based models in this field aims to produce objective, reproducible, non-invasive data-driven methods of embryo selection ensuring higher success rates of ART while simultaneously reducing manual labour and bias. This review focuses on recent (past five years) studies that have implemented AI in embryo selection, indicating the role that AI has to play in this field and exploring the methodologies and performances of such AI models.

Literature review

The Life Whisperer AI model, a cloud-based deep learning system developed by VerMilyea et al., incorporates ensemble deep learning and computer vision, providing instant viability confidence scores for optical microscope embryo images (VerMilyea et al., 2020). Bormann et al. developed a deep learning model using the Xception Convolutional neural network (CNN) architecture combined with a genetic algorithm to evaluate and rank human blastocysts based on static images taken at 113 hours post-insemination (Charles L Bormann et al., 2020). A deep learning mode based on an Attention Branch Network developed by Sawada et al., being trained on 141,444 time-lapse imagesof 470 transferred embryos, predicted live birth outcomes. The AI not only provided confidence scoresbut also highlighted regions in the embryo images that informed its predictions (Sawada et al., 2021). Another CNN model developed by Zhao et al. automatically segmented early human embryos in time-lapse images during IVF, accurately identifying key morphology enabling precise analysis for embryo selection (Zhao et al., 2021). In an inter-observer variability assessment Fordham et al. concluded that significant discrepancies were observed among subjective manual assessments while their AI model based on data-driven machine learning trained using time lapse imaging of blastocysts, demonstrated higher consistency in their predictions (Fordham et al., 2022).  iDAScore v1.0 developed by Berntsen et al. is a fully automated deep learning model combining a 3D CNN and LSTM layers, to analyze time-lapse embryo image sequencesand predict implantation potential of embryo, providing another automated approach to selecting embryos (Berntsen et al., 2022). Toporcerova et al. presented an embryo score prediction tool that combinesEmbryoScope imagingand small non-coding RNA (sncRNA) profilingfrom theBioMAI model to assess embryo competence during IVF. Applying artificial intelligence, their model could identify two miRNAs and five piRNAs from the sequencing data that could distinguish between competent and non-competent embryos with about 86% accuracy (Toporcerová et al., 2022). Yuan et al. developed an artificial intelligence-based model to non-invasively predict the euploidy status of blastocysts in the context of preimplantation genetic testing for aneuploidy (PGT-A), wherein a convolutional neural network (CNN) was trained to distinguish between euploid and aneuploid embryos, using high-resolution embryo images and associated clinical data. The model demonstrated high predictive accuracy, with performance metrics such as area under the curve (AUC), sensitivity, specificity, and F1 score indicating strong reliability (Yuan et al., 2023). A study by Hall et al. demonstrated the potential of artificial intelligence in predicting the developmental potential of embryos before fertilization from pre-ICSI oocyte images, as opposed to traditional embryo selection based on visual assessment of embryos at later stages of development. Trained over 1000 pre-ICSI oocyte images using federated learning, their AI model achieved an AUC (Area under the receiver operating characteristic curve) of 0.65, with higher AI scores correlating with viable oocyte features like larger zona pellucida and better cytoplasmic appearance (Hall et al., 2024). Cao et al. explored the application of a specific style-based generative adversarial network (StyleGAN) to produce high-quality synthetic blastocyst images, enriching training datasets for AI algorithms. This approach showed potential in high-fidelity embryo imaging, enhanced training datasets, and significantly improved AI-based embryo selection models in IVF (Cao et al., 2024). EVATOM developed by Goswami et al. employs quantitative phase imaging and  AI models- a feature-based model (FBM) and an image-based model (IBM), to classify between healthy, intermediate, and non-viable embryos with high accuracy, achieving F1 scores up to 1.00 on fixed embryos and 0.95 on live ones (Goswami et al., 2024).

Discussion

AI is rapidly transforming ART by offering consistent, standardized scores and non-invasive alternatives to traditional methods that relied on manual visual assessment, subject to inter and intra-observer variability. Models such as Life Whisperer and iDAScore v1.0 have demonstrated high accuracy in predicting embryo viability using static or time-lapse images. AI is rapidly transforming embryo selection in IVF by offering objective, consistent, and non-invasive alternatives to traditional methods that rely on subjective visual assessments. Models such as Life Whisperer and iDAScore v1.0 have demonstrated high accuracy in predicting embryo viability using static or time-lapse images. More advanced approaches, such as those by Hall et al. (2024), take it a step further by predicting embryo potential from oocyte images even before fertilization. Meanwhile, Toporcerova et al. (2022) and Yuan et al. (2023) integrate molecular profiling and euploidy prediction to assess embryo competence more comprehensively. AI also improves standardization across clinics, as shown by Fordham et al. (2022), and enhances dataset diversity using synthetic images (Cao et al., 2024).

The studies discussed thus far, employ a variety of AI and machine learning techniques to improve embryo selection and IVF outcomes. These include convolutional neural networks (CNNs) for embryo image analysis, segmentation, and viability prediction, and ensemble deep learning models like Life Whisperer for viability scoring using optical images. Time-lapse imaging is leveraged in models like iDAScore and Fordham’s ML system to predict implantation outcomes with higher consistency. Attention-based networks (Sawada et al., 2021) and feature-based models (EVATOM) highlight key morphological areas influencing predictions. Multi-modal approaches integrate image data with genetic or molecular information, such as BioMAI model by Toporcerová, that combined EmbryoScope imaging with small non-coding RNAs, and federated learning enables secure model training across clinics (Toporcerová et al., 2022). Additionally, generative adversarial networks such as StyleGAN by Cao et al.( Cao et al., 2024) produce synthetic blastocyst images to augment training datasets, enhancing model performance. These methods demonstrate the growing role of AI in automating and personalizing embryo assessment with high accuracy, reduced subjectivity, and improved IVF success rates.

Conclusion

Artificial intelligence is revolutionizing embryo selection in Assisted Reproduction Technology (ART) by providing data-driven, objective, and non-invasive alternatives to traditional subjective methods. Models utilizing deep learning, time-lapse imaging, molecular profiling, and synthetic data generation have shown promising results in improving embryo viability prediction, standardizing assessments, and reducing observer variability. From static image analysis to pre-fertilization oocyte evaluation and integration of multi-modal data, AI offers significant improvements in accuracy, efficiency, and clinical decision-making. While these technologies are still evolving, their integration into clinical practice holds strong potential to enhance IVF success rates, reduce repeated embryo transfers, and ease the emotional and financial constraints that can be faced by infertile couples

Pixels or Paper? Unpacking the Great Reading Debate in 2025 India

In a nation that reveres storytelling, from ancient epics recited orally to bustling local bookstalls, how we consume our narratives is undergoing a fascinating transformation. The familiar rustle of turning pages now competes with the silent, backlit glow of e-readers and tablets. As we move through 2025, the “Digital vs. Paperback” debate isn’t just a preference; it reflects evolving lifestyles, technologies, and even our relationship with information itself.

So, when you settle down for a read, will it be the comforting weight of paper or the sleek convenience of a screen?

Let’s unpack the arguments.

The Timeless Allure of Paperbacks

For many, the physical book remains an irreplaceable experience. This preference is often rooted in sensory connection and cognitive benefits:

The Sensory Experience: There’s a unique pleasure in holding a paperback. The smell of paper, the texture of the cover, the visual satisfaction of seeing your progress by the thickness of the pages on either side – these tactile and olfactory cues create a richer, more immersive reading experience that digital formats simply can’t replicate. It’s why Browse a bookstore in Jamshedpur remains a beloved pastime for many.

Enhanced Focus and Retention: Numerous studies suggest that reading from print can lead to better comprehension and memory retention, especially for longer or more complex texts. Without the constant temptation of notifications, hyperlinks, or other apps on a device, physical books facilitate a deeper, more linear reading flow, encouraging sustained concentration.

Digital Detox for Your Eyes: In a world where screens dominate our work, communication, and entertainment, a physical book offers a much-needed break for our eyes. Reduced blue light exposure from paperbacks can alleviate digital eye strain, prevent headaches, and contribute to better sleep quality, making them ideal for winding down before bed.

True Ownership and Collectibility: When you buy a paperback, it’s yours. You can lend it, resell it, keep it for generations, or proudly display it on a bookshelf. This sense of tangible ownership and the ability to build a personal library holds significant value for many book lovers.

Durability and Simplicity: Paperbacks don’t need charging, Wi-Fi, or software updates. They are robust, can be read in direct sunlight without glare (unlike many screens), and are immune to battery drainage or technical malfunctions, making them reliable companions anywhere.

The Modern Convenience of Digital Books

Despite the nostalgic pull of paper, digital books, read on e-readers, tablets, or smartphones, offer compelling advantages that cater to modern demands:

Unrivaled Portability: Imagine carrying an entire library – hundreds, even thousands, of books – in a device no heavier than a single paperback. For commuters, travelers, or those with limited space (a common challenge in urban Indian apartments), digital books are a clear winner.

Instant Access and Availability: Want to start reading a new book at 2 AM? With a digital bookstore, it’s just a few taps away. No need to wait for a store to open or for delivery. This instant gratification and endless supply are powerful draws.

Customizable Reading Experience: E-readers allow you to adjust font size, font style, line spacing, and even background lighting. This is a huge benefit for readers with visual impairments, or simply for customizing the comfort level of your reading. Many devices also offer built-in dictionaries, translation tools, and note-taking features.

Cost-Effectiveness (Over Time): While an e-reader device is an initial investment, digital books themselves are often cheaper than their paperback counterparts, especially older titles or during promotions. For voracious readers, the savings can add up significantly. Subscription services like Kindle Unlimited further enhance this value proposition.

Environmental Considerations: The environmental impact is a complex debate. While e-readers require energy and rare earth minerals for manufacturing and charging, paperbacks consume trees, water, and energy for production and transport. Studies suggest that if you read more than a certain number of books (often cited as 15-30) on an e-reader over its lifespan, its environmental footprint becomes lower than buying individual paperbacks.

Searchability: Need to find a specific quote or character name? Digital books offer instant search functions, making it incredibly easy to navigate long texts or revisit details.

The Blended Reality of Reading in India

Data from 2024-2025 in India indicates a nuanced picture. While the digital book market is steadily growing (e-book sales projected to grow at a *CAGR of 5.1% from 2025-2030), paperbacks still hold a dominant share (around 84% revenue share in 2024). This suggests that for many, it’s not an either/or scenario, but a harmonious blend .

Perhaps you prefer a physical novel for a leisurely read on a quiet Sunday afternoon, savouring each page. But for your daily commute on the Mumbai local or Delhi Metro, an e-reader filled with multiple non-fiction titles becomes the practical choice. Or maybe you enjoy the rich illustrations and maps in a physical fantasy book, while quickly downloading a trending bestseller onto your phone.

The “winner” in the digital vs. paperback debate is ultimately you, the reader. By understanding the unique strengths of each format, you can make informed choices that align with your reading habits, lifestyle, and preferences. In 2025 India, the joy of reading isn’t confined to a single format; it thrives in the rich diversity of both pixels and paper.

Aggressive Advertising: Television commercials, social media influencers, and online games constantly promote processed snacks, shaping preferences from a young age.

Lack of Awareness/Time: For busy parents, packaged foods become a convenient option, while some youth may lack adequate knowledge about healthy eating.

The Alarming Consequences for Indian Youth

The shift towards junk food is having a profound and alarming impact on the health of India’s young generation:

Obesity and Overweight: Junk food’s high calorie density and low satiety lead to overeating, contributing to a significant rise in childhood and adolescent obesity. This, in turn, increases the risk of chronic diseases later in life.

Nutritional Deficiencies: Despite consuming more calories, youth consuming junk food often suffer from a lack of essential micronutrients like vitamins, minerals, protein, and fiber, leading to “hidden hunger” and impaired physical and mental development.

Metabolic Disorders: The surge in sugar and unhealthy fat intake is directly linked to an increased risk of Type 2 Diabetes (even in adolescence), high blood pressure, and high cholesterol – conditions once primarily associated with adults.

Digestive Issues: Low fiber content in junk food contributes to constipation, bloating, and other gastrointestinal problems.

Dental Problems: Excessive sugar in soft drinks and processed snacks leads to widespread tooth decay and gum disease.

Mental Health Impact: Emerging research suggests a correlation between a diet high in processed foods and an increased risk of mental health issues like depression, anxiety, and poor concentration. Fluctuations in blood sugar can also affect mood and energy levels.

Reduced Physical Performance: A diet lacking vital nutrients can lead to lethargy, reduced stamina, and overall poorer physical performance in sports and daily activities.

Addressing the Challenge: A Collective Responsibility

Tackling this growing health crisis requires a multi-pronged approach involving government, schools, parents, and the youth themselves:

Government Initiatives: The Food Safety and Standards Authority of India (FSSAI) is at the forefront with initiatives like “Eat Right India.” Campaigns like “Aaj Se Thoda Kam” (promoting reduction in salt, sugar, and fat) and “Trans Fat-Free India” aim to raise awareness. “Eat Right School” integrates nutrition education into curricula, and the “Stop Obesity” campaign (launched in June 2025) targets a nationwide reduction in salt and oil consumption. Regulations on misleading advertising, especially for child-targeted ads, are crucial.

School Policies: Promoting healthier canteen menus, providing nutrition education, and encouraging physical activity within school premises.

Parental Guidance: Parents play a vital role in modeling healthy eating habits, preparing nutritious meals at home, limiting junk food availability, and educating children about mindful eating.

Youth Empowerment: Encouraging critical thinking about food choices, involving them in meal preparation, and highlighting the benefits of traditional Indian foods.

Promoting Traditional Foods: Reviving the consumption of millets, pulses, and seasonal produce through awareness campaigns and making them more accessible and appealing.

The future health of India’s youth hinges on a conscious return to nutritious, balanced diets. While the convenience of junk food is undeniable, understanding its long-term health implications and actively choosing traditional, wholesome options is a battle that needs to be won, one plate at a time.

Unlocking the Universe: ISRO & the Electromagnetic Spectrum 2025

Have you ever looked up at the night sky and wondered what stories those twinkling lights are trying to tell? For centuries, humans have relied solely on the narrow window of visible light to observe the cosmos. But what if I told you that the universe is ablaze with a symphony of light far beyond what our eyes can perceive? This “invisible light” holds the key to unlocking some of the universe’s deepest secrets, and it’s all thanks to the electromagnetic spectrum.

Think of the electromagnetic spectrum as a vast ruler measuring different types of light, organized by their wavelength and frequency. At one end, you have long, low-energy radio waves, the kind that carry your favorite music. At the other end, you find short, high-energy gamma rays, the most energetic form of light. In between lie microwaves, infrared radiation, the familiar visible light we see, ultraviolet radiation, and X-rays.

The amazing thing is that different celestial objects and processes emit different parts of the electromagnetic spectrum. By studying this cosmic “rainbow,” astronomers can piece together a much more complete and vibrant picture of the universe than visible light alone allows. Let’s take a tour through the spectrum and see what each region reveals:

Radio Waves: Whispers from the Cosmos

radio waves cosmos
radio waves cosmos

What they reveal: Cold gas clouds, the afterglow of the Big Bang, pulsars, and the structure of galaxies.

Why they’re important: Radio waves can travel through dust clouds that block visible light, allowing us to see into the heart of galaxies and star-forming regions. Radio telescopes, often massive dishes, collect these faint signals.

ISRO’s Contribution: India has a strong presence in radio astronomy. While primarily ground-based, facilities like the Giant Metrewave Radio Telescope (GMRT) in Pune, though not directly run by ISRO, are world-class instruments that contribute significantly to studying the universe in radio wavelengths. Furthermore, ISRO’s participation in the Square Kilometre Array Observatory (SKAO), the world’s largest radio telescope project, signals a strong future contribution to this field.

Microwaves: The Baby Picture of the Universe

What they reveal: Primarily the Cosmic Microwave Background (CMB), the afterglow of the Big Bang.

Why they’re important: Studying the subtle variations in the CMB provides crucial information about the early universe, its composition, and its evolution.

Infrared Radiation: The Heat Signature of the Universe

What they reveal: The heat emitted by stars, planets, and dust clouds. Newly formed stars still shrouded in dust are bright in infrared.

Why they’re important: Infrared telescopes can peer through dust that obscures visible light, revealing hidden stellar nurseries and distant galaxies whose light has been stretched by the expansion of the universe.

ISRO’s Contribution: ISRO has utilized infrared instruments in its missions. For example, the Spectrometer Infrared (SIR-2) onboard India’s pioneering lunar mission, Chandrayaan-1, studied the lunar surface in infrared to map mineral composition. Future missions, like the planned Venus Orbiter Mission (Shukrayaan-1), may also incorporate infrared instruments to study the Venusian atmosphere and surface.

Visible Light: The Familiar Glow

What it reveals: The light emitted by stars due to their nuclear fusion. This is the part of the spectrum our eyes are sensitive to, allowing us to see planets, stars, and galaxies directly.

Why it’s important: While limited, visible light observations have formed the foundation of astronomy for centuries, providing information about the temperature, composition, and motion of celestial objects.

Ultraviolet Radiation: Energetic Light from Hot Objects

What it reveals: Extremely hot and energetic objects like young, massive stars and active galactic nuclei.

Why it’re important: Earth’s atmosphere blocks most ultraviolet radiation, so UV telescopes in space are crucial for studying these high-energy phenomena.

ISRO’s Contribution: A cornerstone of ISRO’s astronomical endeavors is AstroSat, India’s first dedicated multi-wavelength space observatory. Its Ultra Violet Imaging Telescope (UVIT) is a key instrument, capable of observing in both near and far ultraviolet bands. UVIT has made significant discoveries, including detecting extreme-UV light from one of the earliest galaxies, AUDFs01, a groundbreaking observation.

X-rays: Violent Events in the Cosmos

What they reveal: Extremely hot gas in environments like supernova remnants, around black holes, and in galaxy clusters.

Why they’re important: X-ray astronomy allows us to study the most energetic events in the universe, such as material falling onto black holes and the shockwaves from exploding stars.

ISRO’s Contribution: AstroSat carries multiple X-ray payloads, including the Soft X-ray Telescope (SXT), Large Area X-ray Proportional Counter (LAXPC), and Cadmium Zinc Telluride Imager (CZTI), enabling simultaneous observations across a broad X-ray energy range. More recently, ISRO launched XPoSat (X-ray Polarimeter Satellite) in January 2024, India’s first dedicated mission to study the polarization of cosmic X-rays. XPoSat’s instruments (POLIX and XSPECT) are providing crucial insights into the magnetic fields and emission mechanisms of pulsars, black hole binaries, and other extreme X-ray sources, complementing international missions.

Gamma Rays: The Universe’s Most Energetic Explosions

What they reveal: The most violent events in the universe, such as supernova explosions, neutron star mergers, and active galactic nuclei. Gamma-ray bursts are the most powerful explosions known.

Why they’re important: Studying gamma rays helps us understand the physics of extreme environments and the most energetic processes in the cosmos.

ISRO’s Contribution: While not a dedicated gamma-ray observatory on its own, AstroSat’s CZTI (Cadmium Zinc Telluride Imager) also has capabilities in the hard X-ray and low-energy gamma-ray range, contributing to the study of these high-energy phenomena.

Seeing the Universe in Multiple Wavelengths: The ISRO Advantage

The true power of modern astrophysics lies in observing the same celestial object across the entire electromagnetic spectrum. ISRO’s AstroSat, with its unique ability to perform simultaneous multi-wavelength observations (UV, optical, and X-ray), exemplifies this approach. By combining data from these different “eyes,” astronomers can build a comprehensive understanding of an object’s nature, its physical processes, and its place in the universe.

So, the next time you gaze at the night sky, remember that the visible light you see is just one small part of a much grander cosmic picture. Institutions like ISRO, armed with advanced telescopes and a commitment to cutting-edge research, are constantly revealing the hidden beauty and intricate workings of our amazing universe, one wavelength at a time, solidifying India’s position on the global map of space astronomy.
