Study identifies a new "seeding" process in neurons that could be a cause of dementia and Alzheimer's disease.

Exposure to air pollution during childhood has a detrimental effect on cognition sixty years later.

The behavior of the solvated electron e-aq has fundamental implications for electrochemistry, photochemistry, high-energy chemistry, as well as for biology--its nonequilibrium precursor is responsible for radiation damag...

(American Chemical Society) Enveloped viruses have been detected in raw sewage and sludge, but scientists still don't fully understand the fate and infectivity of these viruses during water purification at treatment plan...

Researchers have identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS).

Researchers identified specific genetic variants and families of gut microbes associated with anxiety-like behavior, including host genes that influence anxiety indirectly.

Common spiders sometimes capture prey much larger than themselves, and they use many strands of silk to lift their prey off the ground and render it helpless

Sex hormones play a crucial role in brain health, especially when it comes to the sex-based risk factors associated with dementia.

IndCl, a drug that improves myelination and reduces motor disability, appears to improve visual problems associated with multiple sclerosis.

Piezoelectric materials hold great promise as sensors and as energy harvesters but are normally much less effective at high temperatures, limiting their use in environments such as engines or space exploration. However, ...

Women with multiple sclerosis (MS) may not be at a higher risk of pregnancy complications like gestational diabetes, emergency cesarean section or stillbirth than women who do not have the disease, according to a new stu...

Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors. Cancer immunotherapy has some remarkable successes, but ...

Muscle wasting, or the loss of muscle tissue, is a common problem for people with cancer, but the precise mechanisms have long eluded doctors and scientists. Now, a new study gives new clues to how muscle wasting happens...

New research suggests that a class of drugs called PARP inhibitors, designed to treat hereditary forms of ovarian and breast cancer, don't work the way we thought they did. It also paints a fuller picture of how they wor...

Researchers have developed a unique inkjet printing method for fabricating tiny biocompatible polymer microdisk lasers for biosensing applications. The approach enables production of both the laser and sensor in a room t...

A scientific detective story starting with a single patient in Pittsburgh unearths how the SARS-CoV-2 virus mutates to create new variants, including the UK strain B.1.1.7, and escapes neutralizing antibodies.

Researchers demonstrate why some ovarian cancer patients evolve better than others and suggest possible approaches to improve patient outcomes.

New research demonstrates that scalp cooling physically protects hair follicles from chemotherapy drugs. It is the world's first piece of biological evidence that explains how scalp cooling actually works and the mechani...

For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity. Tracking microbial life across the planet, researchers show that biodiversi...

A research team is using 3D printing to produce a new type of bioresorbable airway stent. This could greatly simplify the future treatment of upper airway obstruction.

New technology has the potential to accelerate uptake and development of on-chip diagnostic techniques in parts of the world where rapid diagnoses are desperately needed to improve public health, mortality and morbidity.
