A mulching film that protects plants without pesticides or plastics

2025-11-21
Whether you’re a home gardener or an industrial farmer, you might be familiar with mulching films — plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these films can release damaging microplastics and don’t have any insect-repelling power. So, a team reporting in ACS Agricultural Science & Technology has developed an alternative biodegradable mulching film that also naturally repels pests using citronella oil. “This research shows that it is possible to protect crops using biodegradable ...

With their Stress-Guided Lightweight 3D Designs (SGLDBench) benchmark, the researchers have succeeded in overcoming these serious obstacles. SGLDBench standardizes lightweight design methods SGLDBench permits six reference strategies such as classical topology optimization, ...

Improve diet and increase physical activity at the same time to limit weight gain, study suggests

2025-11-21
Improving diet and increasing physical activity levels together may be more effective at preventing weight gain – particularly harmful fat inside the abdomen – than just changing one of these behaviours, new research from the University of Cambridge suggests. An analysis of changes in physical activity and diet quality in UK adults found that while improved diet quality and increased physical activity were each independently associated with lower increases in body fat, the greatest benefits were achieved by combining both.   Body fat is stored in different locations, some of which are more harmful than others. Subcutaneous ...

A surprising insight may put a charge into faster muscle injury repair

2025-11-21
At the cellular level, the mechanics of how muscle tissue repair occurs gets complicated.

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 ...

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 ...
