Makeup wearers may be absorbing and ingesting potentially toxic per- and polyfluoroalkyl substances (PFAS), according to a new study. The researchers found high fluorine levels--indicating probable presence of PFAS--in about half of makeup tested. Some products underwent further analysis and were all confirmed to contain at least four PFAS of concern. Most products had no PFAS listed on the label.

More than 50 species of tree snail in the South Pacific Society Islands were wiped out following the introduction of an alien predatory snail in the 1970s, but the white-shelled Partula hyalina survived.

Malicious COVID-19 online content -- including racist content, disinformation and misinformation -- thrives and spreads online by bypassing the moderation efforts of individual social media platforms, according to a new study by researchers at the George Washington University.

Researchers have discovered a new and more efficient computing method for pairing the reliability of a classical computer with the strength of a quantum system.

Targeted encroachment can benefit existing franchisees.

The information presented in this study is primarily positioned to benefit scientists and experts in Cellular Physiology and Histochemistry where new tools to discover therapeutic targets for muscle atrophy are needed. The study outlines the development of a new fluorescent reporter mouse line to detect changes in mitophagy activity. These findings could revolutionize treatment strategies and possibly facilitate interventions to reverse disuse-induced muscle atrophy.

A research team at Korea Institute of Science and Technology (KIST) proposes a method that can stably manage the microbial population in recirculating hydroponic cultivation systems. The research team conducted an integrated analysis of the microbial growth characteristics by constructing a model that simulates the flow of water and nutrients, and the inflow, growth, and discharge of microorganisms in recirculating and non-circulating hydroponic cultivation systems.

Millions of people experience intimate partner violence (IPV) in their lifetime and assessment is important in conducting therapy and assisting victims. A team of psychologists at Binghamton University, State University of New York have evaluated dozens of available measures used to assess intimate partner violence and have pinpointed the most effective ones.

New research about the fate of krill--one of the most abundant species on Earth--during this century has important implications for not only the Antarctic food web, but for the largest commercial fishery in the Southern Ocean.

With preseason football training on the horizon, a new study shows that head impacts experienced during practice are associated with changes in brain imaging of young players over multiple seasons.

Nearly one in four teachers may leave their job by the end of the current (2020-'21) school year, compared with one in six who were likely to leave prior to the pandemic, according to a new RAND Corporation survey. Teachers who identified as Black or African American were particularly likely to consider leaving. These results suggest potential immediate and long-term threats to the teacher supply.

When young adults are more interested in socializing and casually dating, they tend to drink more alcohol, according to a new paper led by a Washington State University professor.On the other hand, scientists found that when young adults are in serious relationships, are not interested in dating or place less importance on friendship, their alcohol use was significantly lower.

A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer's disease, a new study shows.

Researchers examined the frequency and severity of head impacts experienced by youth football players and how exposure to head impacts changes from one year to the next in returning players. The researchers then compared the resulting data with findings on neuroimaging studies obtained over consecutive years in the same athletes. The comparison demonstrated a significant positive association between changes in head impact exposure (HIE) metrics and changes in abnormal findings on brain imaging studies.

New AI software developed by researchers at Flinders University shows promise for enabling timely support ahead of relapse in patients with severe mental illness. In the trial of 304 patients, the AI2 software found that 10% of them were at increased risk of not adhering to treatment plans by failing to take medication or disengaging with health services. This led to interventions which clinicians believe could have prevented the patient from relapsing and experiencing a deterioration of their mental health.

A team of scientists at Nanyang Technological University, Singapore (NTU Singapore) has developed millimeter-sized robots that can be controlled using magnetic fields to perform highly maneuverable and dexterous manipulations. This could pave the way to possible future applications in biomedicine and manufacturing.

POSTECH-Dong-A University College of Medicine joint research team presents an innovative eye surface reconstruction method using the photocrosslinked mussel adhesive protein.

UW researchers have developed a deep learning method that can produce a seamlessly looping, realistic looking video from a single photo

In a study published today in the Annals of Internal Medicine, Johns Hopkins Medicine researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 -- the virus that causes COVID 19 -- more than the standard two-dose regimen for people who have received solid organ transplants.
