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.

In patients with mild cognitive impairment, taking lipophilic statins more than doubles their risk of developing dementia compared to those who do not take statins. According to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting, positron emission tomography (PET) scans of lipophilic statin users revealed a highly significant decline in metabolism in the area of the brain that is first impacted by Alzheimer's disease.

A novel PET radiotracer has been shown to effectively measure increases in brain tau--a distinguishing characteristic of Alzheimer's disease--before any symptoms of the disease are observed. With the potential to measure increases in tau over a long period of time, this tracer offers an important tool to assess the effectiveness of Alzheimer's disease treatments in clinical trials. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

A protein that is critical in cancer cell metabolism has been imaged for the first time with a newly developed radiopharmaceutical, 18F-DASA-23. Imaging with this novel agent has the potential to improve the assessment of treatment response for patients, specifically those with brain tumors. This study was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

The use of 'ice' flavoured e-cigarettes may be common and positively associated with conventional smoking and nicotine dependence among young adults, suggests research published online in the journal Tobacco Control.

A study by University of Rhode Island researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected.

A case series published in Annals of Internal Medicine found that a third dose of vaccine increased antibody levels in organ transplant recipients who had suboptimal response to standard vaccination. These findings suggest that clinical trials are warranted to determine whether booster doses should be incorporated into clinical practice for transplant patients, just as they have been for hepatitis B and influenza vaccinations. This is the first study to report on response to a third vaccine dose.

To understand just how COVID-19 affected human movement on a global scale, researchers in the University of Miami College of Arts and Sciences Department of Geography and Sustainable Development developed COVID-19 vs. Human Mobility, an innovative and interactive web application that shows the connections between human mobility, government policies, and cases of COVID-19.

Through a pre-clinical study conducted in his former role at Moffitt Cancer Center and published in Clinical Cancer Research, Said Sebti, Ph.D., associate director for basic research at VCU Massey Cancer Center, identified a novel drug that effectively thwarts pancreatic tumors that are addicted to the cancer-causing mutant KRAS gene.

By combining wind speed data with the measured accelerations of a golden eagle outfitted with GPS tracking instruments, researchers suggest that, rather than hindering flight, turbulence is a source of energy that birds may use to their advantage.
