Self-healing coatings are advanced materials that can repair damage, such as scratches and cracks on their own. Researchers have developed an efficient method for preparing self-healing films consisting of alternating layers of highly cross-linked organosiloxane and linear polydimethylsiloxane (PDMS). Their film is more durable than conventional self-healing PDMS materials, offering superior hardness and greater thermal stability while self-healing at mild temperatures, paving the way for stronger, more rel Read more ›

Linoleic acid, an omega-6 fatty acid found in seed oils such as soybean and safflower oil, and animal products including pork and eggs, specifically enhances the growth of the hard-to-treat 'triple negative' breast cancer subtype, according to a preclinical study. The discovery could lead to new dietary and pharmaceutical strategies against breast and other cancers. Read more ›

Researchers present gum tragacanth as a plant-based alternative to gelatin for creating edible films. The team developed films containing different concentrations of gelatin and gum tragacanth and monitored their survivability in water and saline solutions. They found the optimal combination of gum tragacanth and gelatin for maintaining the gelatin's gel-like behavior was a 3-to-1 ratio of the two, respectively. However, gum tragacanth's inclusion leads to a more porous film, making... Read more ›

A new form of tumor infiltrating lymphocyte (TIL) therapy, a form of personalized cancer immunotherapy, dramatically improved the treatment's effectiveness in patients with metastatic gastrointestinal cancers, according to results of a clinical trial. The findings offer hope that this therapy could be used to treat a variety of solid tumors, which has so far eluded researchers developing cell-based therapies. Read more ›

Mountain snowpacks accumulate snow throughout the winter, building up stores of water that will supply communities across the American West throughout the long dry season. Now, a new study shows that as storms carry snow to the Rocky Mountains, they are also bringing mercury and other contaminants from mines in the region. The research helps scientists understand how contaminants are spread by atmospheric circulation and has implications for snowpack preservation... Read more ›

Human thermoregulation limits are lower than previously thought, indicating that some regions may soon experience heat and humidity levels exceeding safe limits for survival. The study underscores the urgent need to address climate change impacts on human health, providing vital data to inform public health strategies and climate models. Read more ›

A new study warns that global climate change may have a devastating effect on butterflies, turning their species-rich, mountain habitats from refuges into traps. Think of it as the 'butterfly effect' -- the idea that something as small as the flapping of a butterfly's wings can eventually lead to a major event such as a hurricane -- in reverse. The new study also suggests that a lack of comprehensive global... Read more ›

Researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called 'forever chemicals.' A new study unveils a method that not only eliminates PFAS from water systems but also transforms waste into high-value graphene, offering a cost-effective and sustainable approach to environmental remediation.

AI mental health apps may offer a cheap and accessible way to fill the gaps in the overstretched U.S. mental health care system, but ethics experts warn that we need to be thoughtful about how we use them, especially with children. Read more ›

People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which affect biological processes in the body. However, researchers have now shown that precisely these components disappear within hours and that previous measurements therefore completely underestimate the quantities in which they are present.

Every night, bats emerge out of roosts in massive numbers, creating what scientists have called a 'cocktail party nightmare' of clashing echolocations. Nobody knew how bats managed this severe sensorial challenge. Now, scientists have tracked bats within a group of thousands to find out: when bats first emerge from the roost, they increase their distance from the center of the group and adjust their echolocation to maneuver safely in the...

A new study on the genetic causes of the PTEN Hamartoma Tumour Syndrome (PHTS) has found that inhibitors of the PI3ka pathway, commonly used as anticancer drugs, are also effective against this disease, reducing the extent of vascular malformations and lesion-associated pain in animal models. The research suggests the repurposing of these drugs may offer a new hope for PHTS patients, especially at younger ages. Read more ›

A new artificial intelligence tool could aid in limiting or even prevent pandemics by identifying animal species that may harbor and spread viruses capable of infecting humans. The machine learning model analyzes host characteristics and virus genetics to identify potential animal reservoirs and geographic areas where new outbreaks are more likely to occur. Read more ›

As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 individual protein molecules called nuclear pore complexes (NPCs) pepper the dividing membrane, serving as gateways for materials and messages entering and exiting the nucleus. While the basic need for this shuttle service is constant, scientists have... Read more ›
