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!"

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.
Using advanced analysis based on full genome sequences, researchers have found evidence that modern humans are the result of a genetic mixing event between two ancient populations that diverged around 1.5 million years ago. About 300,000 years ago, these groups came back together, with one group contributing 80% of the genetic makeup of modern humans and the other contributing 20%.
For the last two decades, the prevailing view in human evolutionary genetics has been that Homo sapiens first appeared in Africa around 200,000 to 300,000 years ago, and descended from a single lineage. However, these latest results, reported in the journal Nature Genetics, suggest a more complex story.
For a long time, it's been assumed that we evolved from a single continuous ancestral lineage, but the exact details of our origins are uncertain.
This new research work shows clear signs that our evolutionary origins are more complex, involving different groups that developed separately for more than a million years, then came back to form the modern human species.
While earlier research has already shown that Neanderthals and Denisovans—two now-extinct human relatives—interbred with Homo sapiens around 50,000 years ago, this new research suggests that long before those interactions—around 300,000 years ago—a much more substantial genetic mixing took place.
Unlike Neanderthal DNA, which makes up roughly 2% of the genome of non-African modern humans, this ancient mixing event contributed as much as 10 times that amount and is found in all modern humans.
The team's method relied on analyzing modern human DNA, rather than extracting genetic material from ancient bones, and enabled them to infer the presence of ancestral populations that may have otherwise left no physical trace. The data used in the study are from the 1000 Genomes Project, a global initiative that sequenced DNA from populations across Africa, Asia, Europe, and the Americas.Have you ever heard of—or even seen—red lightning? These are not animated characters but real atmospheric phenomena known as electrical discharges that occur high above thunderstorms. Scientists refer to them as "red sprites," named for their jellyfish-like appearance and vivid red flashes. Now, imagine witnessing these mesmerizing displays over the world's highest mountain range—the Himalayas.
On the night of May 19, 2022, two Chinese astrophotographers, Angel An and Shuchang Dong, captured a spectacular display of over one hundred red sprites over the Himalayas. The observation site, located on the southern Tibetan Plateau near Pumoyongcuo Lake—one of the region's three sacred lakes—revealed a breathtaking celestial event.
Among the phenomena captured were dancing sprites, rare secondary jets, and the first-ever recorded case in Asia of green airglow at the base of the nighttime ionosphere, dubbed "ghost sprites." This extraordinary event attracted global attention and was widely covered by major media outlets.
A recent study published in Advances in Atmospheric Sciences by Professor Gaopeng Lu and his team at the University of Science and Technology of China sheds light on the driving force behind this grand "sprite fireworks"—lightning and thunderstorms.
By analyzing the parent lightning discharges, they discovered that the sprites were triggered by high-peak current positive cloud-to-ground lightning strikes within a massive mesoscale convective system. This suggests that thunderstorms in the Himalayan region have the potential to produce some of the most complex and intense upper-atmospheric electrical discharges on Earth.
Lacking precise timestamps for detailed analysis, the research team developed an innovative method to synchronize video time using satellite trajectories and star field analysis. This innovative approach allowed them to determine the exact occurrence times of the sprites and link them to their parent lightning discharges. One of the anonymous reviewers praised the technique, highlighting its potential as a reliable timing tool for citizen scientists contributing to scientific observations.
The study revealed that the parent lightning discharges occurred within stratiform precipitation regions of a mesoscale convective complex stretching from the Ganges Plain to the southern foothills of the Tibetan Plateau. This event recorded the highest number of sprites during a single thunderstorm in South Asia, suggesting that thunderstorms in this region possess upper-atmospheric discharge capabilities comparable to those in the U.S. Great Plains and offshore European storms.
Moreover, the findings indicate that these storms may generate even more complex discharge structures, potentially influencing atmospheric coupling processes with significant physical and chemical effects.

Some notoriously difficult-to-treat infections may not be as resistant to antibiotics as has been thought, according to new research using a microfluidic device that more closely duplicates the fluid flow found in the body than standard cultures.
Researchers tested antibiotic agents against Pseudomonas aeruginosa, considered one of the most highly resistant pathogens. They introduced the drugs at varying rates of fluid flow and found that, while the bacteria thrived at no or low fluid flow, the antibiotics killed the bacteria at higher flow rates.
Anytime you take an antibiotic orally or by IV, it's not immediately in the place it is supposed to be. It will get there by flowing in the bloodstream. Other fluids move throughout the body as well: in the lungs, the urinary tract, the digestive tract.
So it is important to know the impact of fluid flow. By using the microfluidic technology, often used in engineering, in a biology setting, the researchers found that fluid flow is very important for antibiotic activity.
Whether in a biology lab or a clinical lab, the standard way to study pathogenic bacteria is in plates, tubes or wells—settings not representative of the dynamics found in the body. The microfluidic devices the present group used allow for precise control of the rate of fluid flowing.
The researchers tested three different antibiotic agents against which the Pseudomonas was supposedly resistant. They saw a gradient of antibiotic activity that was dependent on the flow rate. At no to low flow, the antibiotics affected only the bacteria at the very start of the fluid track. As the flow rate increased, so did the reach of the antibiotic activity, until the entire culture sample was wiped out at the highest tested flow rates.
The findings highlight how we could do a better job of characterizing antibiotic resistance. If you get an infection, a clinician might take a sample and test it to see which drugs will work against it. But they're testing it without flow. So they may not give you a drug that actually could be effective because their tests don't show how effective the drugs are in flow conditions like in the body.
When researchers try to develop a new drug, it's the same thing; they might be wrong in interpreting whether the drug is working or not, because the testing conditions aren't like the body.
Next, the research team plans to test other antibiotic-resistant pathogens and other antibiotic drugs in their microfluidic devices. They also hope to more deeply study the mechanisms behind why the antibiotics were more effective in flowing fluid.
That is why I wrote several times that lab conditions will be different from actual conditions. Several factors affect the outcomes and until we test all of them, we cannot say our results are hundred percent correct.

Cancer researchers at Children's Medical Research Institute have discovered an "unexpected mechanism" that our cells use to avoid cancer.
Telomeres are the protective caps at chromosome ends and are involved in aging and cancer. As we age, telomere length naturally decreases. Over the course of a lifetime, telomere shortening instructs aging cells to stop dividing. This normally functions as a critical barrier to stop cancer.
Most people think of telomeres as a passive entity that shorten with cell division; this is a passive fail-safe used during aging.
The new data shows telomeres are much more active. They can acutely respond to stress and actively open up to turn on a cellular response that looks like aging. They do this to avoid cancer.
This can lead to cell cycle arrest, or death, to prevent these damaged cells with chromosome errors from dividing further. This suggests telomeres have another anti-cancer mechanism that was previously unknown.

Children under eight should not drink slushy ice drinks containing glycerol, researchers have warned after a string of hospitalizations in the UK and Ireland.
The brightly colored drinks marketed towards children often use glycerol as a sweetener and anti-freezing agent. But high levels can be harmful, especially to children—glycerol intoxication can cause shock, low blood sugar and loss of consciousness.
In a peer-reviewed medical review published in the Archives of Disease in Childhood journal this week, researchers looked into a "recent apparent surge in cases" in the UK and Ireland, and suggested children under eight should avoid the drinks entirely. They studied the medical records of 21 children aged two to seven who needed emergency treatment after drinking slushies.
Most cases took place between 2018 and 2024 and many of the children became acutely ill within an hour, the researchers said. Most of the children lost consciousness and showed signs of high blood acidity and low sugar, while four needed brain scans and one had a seizure.
The children all recovered swiftly, the researchers said.
Food safety agencies in the two countries already advise that children aged four and under should not have slushies containing glycerol.
But the researchers said the age should be raised further.
"Younger children, especially those under eight years of age, should avoid slush ice drinks containing glycerol," they said.
"Clinicians and parents should be alert to the phenomenon, and public health bodies should ensure clear messaging."
The review's authors also said there could be cases where children have suffered less serious illness and not been taken to hospital.

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells—which compose the linings of our skin, organs and body cavities—are mute, serving mostly as protective barriers that can absorb and secrete various substances.
But researchers have upended the status quo by showing that epithelial cells do indeed "talk" to each other, albeit with slow electrical signals.
The discovery, published in the Proceedings of the National Academy of Sciences, could enable new applications for everything from wearable bioelectric sensors to wound healing.
Epithelial cells do things that no one has ever thought to look for. When injured, they 'scream' to their neighbors, slowly, persistently and over surprising distances. It's like a nerve's impulse, but 1,000 times slower.
The researchers' curiosity-driven approach, blending polymer science and biology, unveiled this hidden cellular signaling.
They used an epithelial-cell-coated chip with 60 precisely placed electrodes to eavesdrop. They grew a single layer of human epithelial cells on the chip, which detected minute electric shifts.
Using a precise laser to produce "sting" patterns of individual cells, they watched as signals rippled outward. They tracked how cells coordinated their response. "It's a slow-motion, excited conversation."
Unlike the swift neurotransmitter bursts of nerve cells, epithelial cells rely on ion flows—of calcium, especially—that produce signals that are far slower than those in nerve cells, but with similar voltages. These signals can be long-lived: The researchers observed cells that "talked" for over five hours across distances nearly 40 times their own length.
They showed that calcium ions are necessary for epithelial conversation, they have yet to test what else might contribute to the conversation. And though the immediate applications of their new discovery remain to be seen, the implications are vast. Wearable sensors, implantable devices and faster wound healing could grow from this .

The natural process of locking away carbon dioxide (CO2) appears to be in decline—and climate change will accelerate as a result, a new study warns.
Researchers found that the levels of CO2 retained in vegetation through this process, which is known as sequestration, had been increasing at 0.8% per year in the 1960s, but peaked in 2008 and are now falling at 0.25% per year.
If its growth rate of the 1960s had continued, natural sequestration would have increased by 50% from 1960 to 2010, but if its current rate of decline continues, it will have reduced by half in 250 years.
Sequestration offsets some of the emissions generated by human activity, which have recently been increasing by around 1.2% a year. Canceling this out would require these emissions to fall by 0.3% annually—equivalent to around 100 million tons of CO2.
The study is published in the journal Weather.

Over the last 40 years, the majority of the world's lakes have changed color, according to a new study. The research team analyzed 32 million satellite observations from over 67,000 lakes. Major changes in the lake ecosystems are thought to be the cause.
Lakes are critical components of Earth's ecosystem. They provide habitats for aquatic and terrestrial species, support biodiversity and help maintain ecological balance. Lakes are also crucial for providing drinking water, supporting agriculture and influencing the climate through their effects on temperature, humidity and atmospheric processes.
The color of lakes is an important indicator of how healthy they are. Different shades reveal the ecological state of lakes and the ongoing physical and biochemical processes.
In a study published in Water Resources Research, a team of researchers analyzed 32 million satellite images of over 67,000 lakes from 1984 onwards.
After cross-checking with climate and population data, the researchers found that only 14% of the lakes studied maintained stable colors over time. The fact that so many lakes have changed color indicates significant ecosystem disruption caused by changes in water quality, algae concentrations, the flux of dissolved organic matter, and other contributing factors.
The results show the strong correlation between changes in lake colors, climate change and human impact.
Lakes have different colors depending on where they are located. Blue lakes are primarily located in areas at northern latitudes, while green lakes are more prevalent in densely populated mid-latitude regions, such as southern Europe. Reddish and yellowish lakes are mainly found in the Southern Hemisphere.
In the study, the researchers found that most of the lakes have shifted toward shorter wavelengths (toward blue) over the last 40 years. A lake with a bluer color generally indicates clearer water and may reflect a healthier ecological state, although this will vary depending on the natural characteristics of the lake and its surroundings.
However, significant changes in lake color can signal ecological disturbances, such as increased nutrient loads or other drivers affecting the physical and biochemical properties of lake water. The differences between regions were remarkable.
Lakes in high-latitude regions, such as North America and northern Europe, showed a more pronounced change in color compared with those at the Equator and in the Southern Hemisphere. We don't really know why this is the case. This regional variation suggests that climate change and human activity are impacting ecosystems in complex and localized ways.
By mapping lake colors globally, the new study highlights how climate change and human activity are affecting lake ecosystems, which in turn have a major impact on food production, water supply and recreation. Understanding these changes can help communities and policymakers make informed decisions about water resource management, conservation and environmental protection.

A small team of computational and evolutionary biologists reports that unique lactase genes carried by about 25% of East Asian people may have been inherited from Neanderthals.
In their study published in Proceedings of the National Academy of Sciences, the group compared the genes of thousands of people of African, East Asian and European descent against one another and then against Neanderthal genes.
Prior research has shown that many people of European descent carry genes that allow them to easily digest the sugars (lactose) present in milk, in sharp contrast to people of East Asian descent, who tend to have a high percentage of lactose intolerance.
However, in this new effort, the research team found unique versions of the lactase gene in some East Asian people along with evidence that they may have come from interbreeding between humans and Neanderthals thousands of years ago.
The researchers compared thousands of genomes collected from people of known European, African or East Asian descent, looking for commonalities between people who were lactose intolerant and those who were not. They found that approximately 25% of the East Asian samples studied carried versions of lactase genes not found in the genes of African or European people.
That led them to then compare those lactase genes from East Asians with genes from Neanderthals. They found that the genes in the East Asian samples likely came from the Neanderthals. This was because the genes showed up in the early humans before they had begun to drink the milk of domesticated animals such as cows, which ruled that out as a source of selection.
Exploring how the Neanderthals might have developed the lactase genes, the team found evidence that they may have provided some degree of protection against infections, a finding that would also explain why the genes persisted in East Asians long after the disappearance of the Neanderthal.
