People who have limited access to air conditioning may be at higher risk of seeking emergency care for health problems following exposure to wildfire smoke, according to a new study. The study found that exposure to fine particle matter (PM2.5) from wildfire smoke in California is associated with higher rates of emergency department visits for all causes, non-accidental causes, and respiratory disease. This risk varied by age and race, but was especially high for individuals who lived in areas with lower availability of air conditioning.

Scientists have now discovered a chemical that plants produce when they're stressed prevents dangerous biofilm from forming. The breakthrough offers potential advances in healthcare as well as preventing equipment corrosion in industrial settings.

Radiation testing suggests that solar cells made from carbon-based, or organic, materials could outperform conventional silicon and gallium arsenide for generating electricity in the final frontier, a study suggests.

Scientists have discovered how plants adapt their root systems in drought conditions to grow steeper into the soil to access deeper water reserves.

Cognitive profiles for early diagnosis of Dementia with Lewy bodies (DLB) have been outlined in a new study. Although DLB is the second most common neurodegenerative dementia following Alzheimer's Disease, it is usually misdiagnosed, preventing affected people from accessing care better tailored to their prognosis.

A study shares new insights into how two of the most common types of chimeric antigen receptor (CAR) T cells kill cancer. Investigators examined how molecular dynamics at the immune synapse -- where CAR T cells bind to cancer cells -- affect anticancer activity.

Women may be missing a diagnosis of a potentially deadly heart condition due to guidelines that don't account for natural differences in sex and body size.

To help rare elkhorn corals survive in Florida waters, coral researchers should place them in shallow ocean locations with fast currents, scientists explained in a recent publication.

An analysis of U.S. mortality data reveals the disproportionate impact of traumatic brain injuries (TBI) on older adults, males and certain racial and ethnic groups.

A look at cancer cells: Thanks to an innovative method of super-resolution microscopy, researchers observed with molecular resolution in 3D how therapeutic antibodies attack and alter B cells, thereby inducing their destruction. Their research presents the new type of molecular 3D visualization of antibody-cell interactions. The visualization of the molecular interaction between antibody and tumor cell opens up new avenues for improved immunotherapies against cancer.

Alloying, the art of blending metals with other elements, has long been a cornerstone of materials science and metallurgy, creating materials with tailored properties. In contrast, dealloying has been known primarily as a corrosive process that degrades materials over time by selectively removing elements, weakening their structure. Now, researchers have turned these two seemingly counteracting processes into an innovative harmonic synthesis concept.

A team developed a method that makes it easy to measure the wrinkles in thin membranes used on large spacecraft using just a single camera.

Scientists have created a catalyst for hydrogen generation from ammonia that becomes more active with time, and by counting atoms revealed changes that boost the catalyst's performance.

Researchers identified a protein and a group of small ribonucleic acids (sRNAs) in Bacteroides thetaiotaomicron, which regulate sugar metabolism. These discoveries shed light on how this gut microbe adapts to varying nutritional conditions. The findings deepen our understanding of this bacterium's role in the human gut and may pave the way for new therapeutic strategies to promote health through the microbiota.

Researchers have shown that a test called ORACLE can predict lung cancer survival at the point of diagnosis better than currently used clinical risk factors. This could help doctors make more informed treatment decisions for people with stage 1 lung cancer, potentially reducing the risk of the cancer returning or spreading.

AI tools are increasingly being used to track and monitor us both online and in-person, yet their effectiveness comes with big risks. Computer scientists have developed a new mathematical model which could help people better understand the risks posed by AI and assist regulators in protecting peoples' privacy.

A study has examined whether an additional blood test called procalcitonin (PCT) could safely shorten the time children spend on intravenous (IV) antibiotics in hospitals. Despite promising previous analysis, the study, found that using the PCT biomarker to guide treatment decisions did not reduce antibiotic duration when compared to usual care.

The way cricket frogs move across the surface of water has long been thought to resemble walking on water, but researchers have now discovered a different reality.

A whitish, grey patch that sometimes appears in the night sky alongside the northern lights has now been explained.

A research team found a key indicator for the chemical activity of acoustic microbubbles and a correlation between the temperature of a liquid and that of the microbubbles generated.
