Scientists identify a molecular switch to a painful side effect of chemotherapy

2025-11-21
Chemotherapy activates a stress sensor in immune cells, triggering inflammation and nerve damage, which may help explain why many cancer patients experience debilitating pain as a side effect, according to a new study by Weill Cornell Medicine and Wake Forest University School of Medicine researchers. Up to half of all patients receiving chemotherapy experience chemotherapy-induced peripheral neuropathy (CIPN), which causes tingling, numbness and pain in the hands and feet. Since there are limited options to address ...

When the air gets dry, cockroaches cuddle: Binghamton University study reveals survival strategy

2025-11-21
When conditions get too dry, Madagascar hissing cockroaches like to "cuddle". Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent research from Binghamton University’s Biological Sciences program, this strategy may prevent the cockroaches from drying out. The new study, “Plastic Behavioral Responses to Ambient Relative Humidity Influence Aggregation in a Large Gregarious Insect”, recently appeared in the journal Ethology, and was co-authored by Binghamton University Assistant ...

Study finds unsustainable water use across the Rio Grande

2025-11-21
Across the Rio Grande–Bravo basin, which runs from Colorado to Mexico, water stress has been building for years. Reservoirs that once relied on steady snowmelt are now noticeably lower. Aquifers that supported farming communities for generations continue to decline, dropping faster than they can recharge. In some stretches, the river, which runs nearly 3,000 kilometers, disappears into dry sand before reaching its endpoint. Despite this growing strain, a full, basin-wide picture of how the river’s water is used and how much is being lost didn’t exist. People could see the symptoms, but ...

Brain “stars” hold the power to preserve cognitive function in model of Alzheimer’s disease

2025-11-21
Researchers at Baylor College of Medicine have discovered a natural mechanism that clears existing amyloid plaques in the brains of mouse models of Alzheimer’s disease and preserves cognitive function. The mechanism involves recruiting brain cells known as astrocytes, star shaped cells in the brain, to remove the toxic amyloid plaques that build up in many Alzheimer’s disease brains. Increasing the production of Sox9, a key protein that regulates astrocyte functions during aging, triggered ...

New CAR T strategy targets most common form of heart disease

2025-11-21
PHILADELPHIA – A pioneering preclinical study has shown that CAR T cell therapy—a personalized form of immunotherapy used in cancer treatment—could be a highly effective tool against atherosclerosis, the condition where a build-up of plaque in the arteries reduces blood flow, leading to heart attacks and strokes. In tests in mice, the experimental CAR T cells blocked inflammation in arteries, preventing more than two-thirds of the plaque buildup seen in untreated controls. The research, led by scientists in the Perelman School of Medicine at the University of Pennsylvania, was published today in Circulation. “Our ...

Why some volcanoes don’t explode

2025-11-21
The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma – and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped while the magma was rising. Gases that were dissolved in the magma in lower strata – due to the higher pressure – escape when the pressure drops and form bubbles. The more bubbles there are in the magma, the lighter it becomes and the faster it rises. This can cause the magma to tear apart, leading to an explosive eruption.  This process can be likened to a bottle of champagne: while the bottle is closed and therefore pressurised, the carbon dioxide remains ...

New stem cell medium creates contracting canine heart muscle cells

2025-11-21
In research, induced pluripotent stem (iPS) cells are derived from skin, urine, or blood samples and developed into other cells, like heart tissue, that researchers want to study. Because of the similarities between certain dog and human diseases, canine iPS cells have potential uses  in regenerative medicine and drug discovery.  Research on iPS cells is challenging because the cells are extremely sensitive to culture conditions. Before they are developed into other cells, iPS cells are in an undifferentiated state. At this stage, the cells are grown in a culture medium that provides the essential nutrients, growth factors, and signaling molecules that they ...

Cute little marsupials pack a punch at mealtimes

2025-11-21
Native Australian animals range from high-hopping kangaroos to fast-running emus – but clever little bettongs also have a special ability to find and eat the food they love.   Flinders University researchers have discovered the secrets behind a superpower of these tiny relatives of kangaroos which allows them to crack open seeds that would break the jaws of most animals. They hope the research will help conservation efforts, including finding suitable locations to reintroduce populations severely impacted by predation and habitat loss.   The new study, published in the Zoological Journal of the Linnean Society, reveals ...

Football draft season raises concerns for young player welfare

2025-11-21
The road to glory in the Australian Football League (AFL) is highly competitive, with as few as 0.01% of more than 640,000 young footballers and athletes from around Australia selected in the annual draft process.  With so many young players pinning their hopes on selection, sport experts from Flinders University have surveyed more than 400 young male Australian footballers (16-18 years old) to evaluate the psychological impact on their mental health and wellbeing during a draft selection year. In the midst of adolescence and crucial stages of life, striving to compete at these levels raises concerns for the effects on young male players, says Associate Professor ...

High prevalence of artificial skin lightening in under 5s, Nigerian survey suggests

2025-11-21
A significant proportion of under 5s in Nigeria may be being exposed to skin lightning products, if the results of a semi-urban community survey are indicative, suggests research published in the open access journal BMJ Open.   Most (80%) of the respondents’ children exposed to skin bleaching products were under 2 years old, and despite good knowledge of the health risks of the practice, these were trumped by aesthetic preferences for lighter skin tones, the survey responses show.   The cosmetic use of skin lightening products has become increasingly common globally, with very high ...

Scientists discover new type of lion roar, which could help protect the iconic big cats

2025-11-21
A new study has found African lions produce not one, but two distinct types of roars - a discovery set to transform wildlife monitoring and conservation efforts. Researchers at the University of Exeter have identified a previously unclassified “intermediary roar” alongside the famous full-throated roar. The study, published in Ecology and Evolution, used artificial intelligence to automatically differentiate between lion roars for the first time. This new approach had a 95.4 per cent accuracy and significantly reduced human bias to improve the identification of individual lions. Lead author Jonathan Growcott from the University of Exeter said: ...

ChatGPT is smart, but no match for the most creative humans

2025-11-20
A new Australian study has smashed the myth that generative AI systems such as ChatGPT could soon replace society’s most creative playwrights, authors, songwriters, artists and scriptwriters. The existing large language models (LLMs) have a built-in mathematical ceiling on their creative capacity, meaning they will never rival the originality or ingenuity of the most creative individuals. That’s the finding from creativity expert David Cropley, a Professor of Engineering Innovation at the University of South Australia, whose study on the mathematical limits of generative AI has been published in the Journal ...
