Brain scans from American football players reveal subtle differences in the brain's outer grooves when compared to scans from otherwise healthy men who never played contact or collision sports, a new study shows.

Low oxygen levels in the blood can alter the genetic makeup of key immune cells, weakening the body's ability to fight infection, new research shows.

As populations continue to age, total hip replacement (THR) is becoming an increasingly common surgical procedure.

An international study led by the Azrieli Faculty of Medicine in the Galilee at Bar-Ilan University reveals that the COVID-19 pandemic has contributed to a diminishing public trust in childhood vaccines, resulting in declining vaccination rates and a resurgence of preventable, life-threatening diseases such as measles.

Every day, 17 Americans die while waiting for an organ transplant. Opt-out organ donation policies, which enroll everyone into post-mortem donation programs by default unless people choose to opt out, have been touted as a way to increase the supply of desperately needed organs.

Microcephaly is a congenital malformation that leads to a significantly reduced brain size and is often accompanied by developmental delay.

Liver cirrhosis is significantly more common in low-income households than in high-income households. This is the result of a national study which, according to the researchers, calls for more preventive action in the most vulnerable groups.

The electronic health record data analyzed in this study is anonymized and never leaves a secure data environment, which is only accessible by approved researchers working on approved projects.

Most people are born with two functioning copies of each gene-one inherited from each parent. In many cases, having just one working copy is enough for the body to function normally.

Metagenomics is the study of all organisms present in a particular environment, such as soil, water, or the human body. A key part of metagenomic analysis is understanding what species are present (classification), how much of each there is (abundance), and the function of the microorganisms present.

An international study led by experts at the University of Sydney and the Universidad Europea in Spain has found that longer periods of continuous walking are more beneficial to cardiovascular health than walking the same number of steps in shorter, more sporadic bouts.

Women living in parts of the United States with lower air quality, especially neighborhoods with heavy emissions from motor vehicles, are more likely to develop breast cancer, according to a multiyear analysis involving more than 400,000 women and 28,000 breast cancer cases.

Results from the PREVUE-VALVE study suggest that there are currently at least 4.7 million people aged 65-85 living with moderate or greater valvular heart disease (VHD) in the United States, and at least 10.6 million with clinically significant VHD, most of whom are unaware of their condition.
