A solution to injuries from slips and falls may be found underfoot -- literally. The footpads of geckos have hydrophilic (water-loving) mechanisms that allow the little animals to easily move over moist, slick surfaces. Researchers report using silicone rubber enhanced with zirconia nanoparticles to create a gecko-inspired slip-resistant polymer. They say the material, which sticks to ice, could be incorporated into shoe soles to reduce injuries in humans. Read more ›

Muon spin rotation ( SR) spectroscopy is a powerful technique used to study the behavior of materials at the atomic level. In this study, researchers employed SR to examine phosphorus-containing 12-phosphatetraphene 1 molecule (muoniated radical). Their findings provide new insights into the radical's structure and behavior, advancing understanding of reactive species and radical behavior. Read more ›

Women who go on to develop postpartum depression (PPD) may have characteristic levels of neuroactive steroids, molecules derived from the hormone progesterone, in their blood during the third trimester of pregnancy, according to a new study. These molecules influence the brain's stress response and emotional regulation. Read more ›

A new study shows that artificial intelligence (AI) can help doctors make better decisions when treating cancer. However, it also highlights challenges in how doctors and AI work together. The study focused on AI-assisted radiotherapy for non-small cell lung cancer and hepatocellular carcinoma (liver cancer). Read more ›

A systematic literature review found no evidence to support that physical exertion without rhabdomyolysis (muscle breakdown) or heat injury can cause sudden death for individuals with sickle cell trait (SCT), nor is there any high-level evidence that SCT causes acute pain crises. Read more ›

Humans do not always age biologically at the same rate as their chronological age. Faster biological aging compared to chronological age has been linked to higher risks of disease and mortality. According to a recent study, a diet low in vegetables and fruits and high in red meat, fast food, and sugar-sweetened soft drinks was associated with accelerated biological aging even in young adulthood.

Studies of sediment cores from the sea floor and the coastal regions surrounding the Aegean Sea show that humans contaminated the environment with lead early on in antiquity. Geoscientists conducted the analyses, which revealed that human activity in the region resulted in lead contamination of the environment approximately 5,200 years ago -- much earlier than previously known. Combined with the results of pollen analyses from the sediment cores, this contamination... Read more ›

Researchers report that a more efficient and environmentally friendly form of refrigeration might be on the horizon. The new technology is based on thermogalvanic cells that produce a cooling effect by way of a reversible electrochemical reaction. Thermogalvanic refrigeration is cheaper and more environmentally friendly than other cooling methods because it requires a far lower energy input, and its scalability means that it could be used for various applications --...

A new study has highlighted the potential of resveratrol, a natural compound found in grapes, blueberries, and raspberries, to enhance female fertility. The systematic review found that resveratrol can improve the quantity and quality of egg cells, offering hope for new, less invasive fertility treatments. Read more ›

The world is experiencing more frequent and intense heat waves, floods, hurricanes, and wildfires due to rising greenhouse gas emissions. The energy sector is one of the largest contributors to climate change, yet it also plays a crucial role in the strategies needed to mitigate and adapt to its effects, contributing to the achievement of ambitious climate goals.

Zaps of static electricity might be a wintertime annoyance, but to certain scientists, they represent an untapped source of energy. Using a device called a triboelectric nanogenerator (TENG), mechanical energy can be converted into electrical energy using triboelectric effect static. Many TENGs contain expensive, specially fabricated materials, but one team has instead used inexpensive store-bought tape, plastic and aluminum metal. Read more ›

The productivity of cacao trees decreases with time, forcing farmers to renew their plantations by either cutting down the old trees or establishing a new crop elsewhere. Frequently, new plantations are established in areas of the forest that are thinned out to accommodate new, young cacao trees. However, this comes with high economic and ecological costs. An alternative approach is to graft highly productive and native cultivars onto the existing... Read more ›
