Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers have now developed a 3D-printed 'brain-like environment' where neurons grow similarly to a real brain. Using tiny nanopillars, they mimic the soft neural tissue and the brain extracellular matrix fibers. This model provides new insights into how neurons form networks, as well as a novel tool to understand... Read more ›

Sharks and rays have populated the world's oceans for around 450 million years, but more than a third of the species living today are severely threatened by overfishing and the loss of their habitat. Palaeobiologists have now investigated whether and how global warming influences the diversity of sharks based on climate fluctuations between 200 and 66 million years ago. According to the study, higher temperatures and more shallow water areas... Read more ›

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 --...
