WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING
THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS
“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”
"Being a scientist is a state of mind, not a profession!"
"Science, when it's done right, can yield amazing things".
The Reach of Scientific Research From Labs to Laymen
The aim of science is not only to open a door to infinite knowledge and wisdom but to set a limit to infinite error.
"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.
Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.
If you are scientifically literate the world looks very different to you.
We do science and science communication not because they are easy but because they are difficult!
“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

Bat vaccine can be spread lickety-split
An oral vaccine could curb rabies infections among vampire bats (Desmodus rotundus) in Central and South America. The vaccine is applied to the bats’ fur in a thick gel. The bats can then spread the vaccine among themselves through mutual grooming — licking one another’s fur to keep clean. In a small test, researchers applied the gel to 24 bats in a colony of 117. After seven days, they found that the vaccine had been spread among 88% of the colony. Vaccinating the bats against rabies could stop them from spreading the virus to farm animals without resorting to harmful measures such as poisons.

More than a decade later, chimpanzees in another group at the same sanctuary also began sticking blades of grass in their ears. They did not copy this behavior from the earlier group, since they had no contact with them. But in the new group, the grass-in-orifice trend did not stop there. While five of the eight chimpanzees in the new group stuck grass in their ears, six of the eight also let a blade of grass dangle from their behinds.
The researchers found no evidence that the chimpanzees were bothered by their ears or behinds and used the blades of grass, for example, for relieving an itch.
By carefully tracking which animals displayed the behavior over time, the researchers showed it was likely that the animals did not each invent the behavior on their own, but copied it from one another. When the researchers looked deeper into how the behavior started, they found something striking.
Both groups, where chimps put blades of grass in their ears, had the same caretakers. These caretakers reported that they sometimes put a blade of grass or a matchstick in their own ears to clean them. Caretakers in the other groups said they did not do this. The chimps in one group then figured out how to stick the blade of grass in another place as well.
In the wild, similar "useless" trends have not been seen in chimpanzees. So why do they do it in captivity?
In captivity, they have more free time than in the wild. They don't have to stay as alert or spend as much time searching for food, say the researchers.
The question of why humans are more culturally evolved than other animals is still being debated by scientists. Some scientists think the key lies in humans' unique ability to copy, including small, seemingly useless details. Other animals would not be able to do this and would have to constantly reinvent the wheel, which limits their cultural evolution.
But this study shows that chimpanzees are able to copy small, useless behaviours from each other.
And this behaviour could also serve a social purpose. By copying someone else's behavior, you show that you notice and maybe even like that individual. So, it might help strengthen social bonds and create a sense of belonging within the group, just like it does in humans.
Edwin J.C. van Leeuwen et al, Chimpanzees socially learn non-instrumental behaviour from conspecifics, Behaviour (2025). DOI: 10.1163/1568539X-bja10313
Part 2
A team of researchers from Utrecht University, Durham University, and other institutions have observed something remarkable at a chimpanzee sanctuary in Zambia. Several chimpanzees from one particular group were seen dangling blades of grass from their ear holes or their behinds, for no apparent reason. The behavior was not seen in other chimpanzee groups at the same sanctuary, despite similar living conditions.
This shows that like humans, other animals also copy seemingly pointless behaviors from one another. And that, in turn, may offer insights into the evolutionary roots of human culture.
People regularly do arbitrary things that seem to have no immediate use, like shaving a line into their eyebrow or putting a fashionable scarf on themselves or their dog. Most people do not come up with these things themselves, but copy them from others.
Other animals also adopt behaviours from one another. Often, though, this is useful behaviour, like chimpanzees learning from each other how to find food. But sometimes, animals develop habits that seem to serve no clear purpose. For instance, a fashion trend among orcas, who were seen wearing a dead salmon on their heads, drew quite a bit of media attention last year. Still, these kinds of "useless" trends in animals have rarely been studied in a systematic way.
In 2010, researchers discovered that a female chimpanzee at the Chimfunshi Wildlife Orphanage Trust sanctuary repeatedly stuck a blade of grass in her ear and left it there, for no apparent reason. Later, seven of her group members adopted the behaviour. And even after the female trendsetter died, the behaviour continued, and some chimps in the group still do it today. Researchers therefore interpreted this behaviour as a cultural tradition.

Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred to as "light dragging," is typically imperceptible when light is traveling in most widely available materials, as the movement is significantly slower than the speed of light. So far, it has thus proved difficult to observe in experimental settings.
Physicists recently observed a specific type of light dragging known as image rotation in a plasma-based system.
Their observation, outlined in a paper published in Physical Review Letters, was made using magnetohydrodynamic (MHD) waves that propagate in a magnetized plasma, known as Alfvén waves.
Using recently demonstrated plasma rotation control capabilities in the Large Plasma Device at UCLA, the researhcers managed to show that they can indeed rotate the wave pattern left and right by some tens of degrees by controlling the plasma rotation.
To realize image rotation in plasma, the researchers leveraged the naturally slow velocity with which Alfvén waves travel. They specifically employed a system in which Alfvén waves are launched in a plasma whose rotation can be controlled using electrically charged electrodes brought in contact with the plasma.
Their efforts led to the observation of image rotation. In other words, they found that the Alfvén waves' transverse structure appeared to twist.
Interestingly, they also found that these effects surprisingly matched those predicted by theories explaining light dragging in isotropic systems, media far simpler than plasmas that exhibit the same properties irrespective of the directions they are observed from, demonstrating a broader validity of these results.

The skeletal muscles of men and women process glucose and fats in different ways. A study conducted recently provides the first comprehensive molecular analysis of these differences. The results, published in Molecular Metabolism, possibly give an explanation for why metabolic diseases such as diabetes manifest differently in women and men—and why they respond differently to physical activity.
Skeletal muscles are far more than just "movement driving motors." They play a central role in glucose metabolism and therefore also in the development of type 2 diabetes. This is due to the fact that around 85% of insulin-dependent glucose uptake takes place in the muscles. This means that if muscle cells react less sensitively to insulin, for example in the case of insulin resistance, glucose is less easily absorbed from the blood. This process is specifically counteracted by physical activity.
The degree to which muscles work differently in women and men has long been underestimated. It is precisely this issue which has now been investigated by researchers now.
The result of the work: The first training session triggered a stronger stress response at the molecular level in men, which became manifest in the increased activation of stress genes and the increase in the muscle protein myoglobin in the blood. In addition, male muscles showed a distinct pattern of what are called fast-twitch fibers, which are designed for short-term, intensive exercise and preferably use glucose as an energy source.
Women had significantly higher amounts of proteins that are responsible for the absorption and storage of fatty acids: an indication of more efficient fat utilization. After eight weeks of regular endurance training, the muscles of both sexes matched and the muscle fiber-specific differences decreased. At the same time, women and men produced more proteins that promote the utilization of glucose and fat in the mitochondria, the "power plants of the cells."
These adjustments indicate an overall improvement in metabolic performance, which can help to reduce the risk of type 2 diabetes.

Chances are that you have unknowingly encountered compelling online content that was created, either wholly or in part, by some version of a Large Language Model (LLM). As these AI resources, like ChatGPT and Google Gemini, become more proficient at generating near-human-quality writing, it has become more difficult to distinguish between purely human writing from content that was either modified or entirely generated by LLMs.
This spike in questionable authorship has raised concerns in the academic community that AI-generated content has been quietly creeping into peer-reviewed publications.
To shed light on just how widespread LLM content is in academic writing, a team of researchers analyzed more than 15 million biomedical abstracts on PubMed to determine if LLMs have had a detectable impact on specific word choices in journal articles.
Their investigation revealed that since the emergence of LLMs there has been a corresponding increase in the frequency of certain stylist word choices within the academic literature. These data suggest that at least 13.5% of the papers published in 2024 were written with some amount of LLM processing. The results appear in the open-access journal Science Advances.
The team also identified notable differences in LLM usage between research fields, countries, and venues.

Researchers have linked brighter night-time light exposure to elevated risks of five major cardiovascular diseases.
Circadian rhythms govern fluctuations in blood pressure, heart rate, platelet activation, hormone secretion, and glucose metabolism. Long-term disruption of those rhythms in animal and human studies have produced myocardial fibrosis, hypertension, inflammation, and impaired autonomic balance.
In the study, "Personal night light exposure predicts incidence of cardiovascular diseases in >88,000 individuals," posted on medRxiv, researchers conducted a prospective cohort analysis to assess whether day and night light exposure predicts incidence of cardiovascular diseases and whether relationships vary with genetic susceptibility, sex, and age.
Brighter nights showed dose-response associations with higher risk across all five outcomes. Participants classified in the 90–100th percentile of night-time light exposure experienced 23–32% higher hazard for coronary artery disease, 42–47% for myocardial infarction, 45–56% for heart failure, 28–32% for atrial fibrillation, and 28–30% for stroke compared with those in the 0-50th percentile.
Relationships persisted after controlling for physical activity, smoking, alcohol, diet, sleep duration, socioeconomic status, and genetic risk. Women displayed stronger associations for heart failure and coronary artery disease whereas younger participants showed stronger associations for heart failure and atrial fibrillation.
Authors propose circadian misalignment induced by unnatural light may trigger metabolic and vascular perturbations that elevate cardiovascular risk. Impaired glucose tolerance and heightened diabetes susceptibility may foster endothelial dysfunction and atherosclerosis.
Light-driven hypercoagulability could increase thromboembolic events, while sustained elevation of 24-hour blood pressure may damage vascular endothelium and provoke myocardial hypertrophy. Conflicting timing signals to sinoatrial and atrioventricular nodes may amplify arrhythmic vulnerability.
Avoiding bright light during habitual sleep times may serve as a practical addition to established cardiovascular prevention strategies, according to the authors, who call for circadian-informed lighting guidance in homes, hospitals, and urban planning.

The plasma-based method this team developed uses electricity to excite nitrogen and oxygen molecules in the air. The team then passes these excited molecules to the membrane-based electrolyzer to convert the excited molecules to ammonia.
The researchers said this is a more straightforward pathway for ammonia production. This new approach is a two-step process, namely combining plasma and electrolysis.

Researchers have harnessed human-made lightning to develop a more efficient method of generating ammonia—one of the world's most important chemicals. Ammonia is also the main ingredient of fertilizers that account for almost half of all global food production.
The research was published in Angewandte Chemie International edition.
The team have successfully developed a more straightforward method to produce ammonia (NH3) in gas form. Previous efforts by other laboratories produced ammonia in a solution (ammonium, NH4+), which requires more energy and processes to transform it into the final gas product.
The current method to generate ammonia, the Haber-Bosch process, comes at great climate cost, leaving a huge carbon footprint. It also needs to happen on a large scale and close to sources of cheap natural gas to make it cost-effective.
Naturally occurring ammonia (mostly in the form of bird droppings) was once so high in demand it fueled wars.
The invention of the Haber-Bosch process in the 19th century made human-made ammonia possible and revolutionized modern agriculture and industry. Currently, 90% of global ammonia production relies on the Haber-Bosch process.
Industry's appetite for ammonia is only growing. For the past decade, the global scientific community has wanted to uncover a more sustainable way to produce ammonia that doesn't rely on fossil fuels.
In this new research scientists have successfully developed a method that allows air to be converted to ammonia in its gaseous form using electricity.

Nearly one in four infants lacks enough healthy gut bacteria essential for training their immune systems, putting them at greater risk of developing non-communicable diseases (NCDs) such as allergies, asthma, and eczema by age 2.
Bifidobacteria are among the first group of good bacteria to colonize the human gut, and their presence has been linked to positive health outcomes for the host, including protection against metabolic diseases, gastrointestinal tract infections, and inflammation.
A recent study published in Communications Biology analyzed the gut microbiomes of 412 infants, selected to represent the diverse demographics of the U.S, and found a widespread deficit of Bifidobacteria in infants. Long-term health data from the infants suggested that a lack of detectable Bifidobacteria in infants may contribute to the development of atopy, a genetic predisposition to developing allergic diseases.
Global estimates suggest that up to 40% of the population has some form of allergy to substances present in the environment—pollen, dust, mites, or animal dander. The last few decades have also witnessed a growing prevalence of allergic conditions among children, ranging from seasonal allergies with mild symptoms, such as a runny nose, sneezing, and itchy eyes, to severe eczema and life-threatening food allergies that can send someone into an anaphylactic shock.
Emerging data suggests that the rise in such NCDs actually begins during the first 1,000 days of a child's life—inside the mother's womb and through the first two years of life. Scientists think that while environmental and lifestyle changes play a role, a key factor may be disruptions in the gut microbiome. In infants, this disruption includes the widespread loss of certain beneficial strains of Bifidobacterium that are essential for early immune development and long-term health.
A baby's mode of delivery (C-section or vaginal birth), whether they were breastfed or formula-fed, and exposure to antibiotics can shape the diversity of their gut microbiome, a factor that has been linked to health issues later in life, including allergies, autoimmune diseases, obesity.
Data analysis revealed that 25% of infants between 1 and 3 months of age were deficient in Bifidobacterium, and the deficiency was more pronounced in C-section births (35%) than in vaginal births (19%). In C-section infants, the beneficial bacteria were often replaced by potentially pathogenic bacteria that are known to use up human milk oligosaccharides, components in breast milk that shape the infant gut microbiome.
They also found that microbiomes rich in Bifidobacterium had fewer antimicrobial-resistant and disease-causing genes, along with more beneficial metabolic profiles.
The researchers highlight that while the term dysbiosis or imbalance in the microbiome is still up for debate, the strong correlation between microbiome composition and infant health suggests that the absence of these key Bifidobacterium strains represents a true dysbiosis in early life.
