The Bajau, a population of sea nomads in Indonesia, are known for their ability to conduct prolonged and repeated deep dives while holding their breath. A new analysis by University of Copenhagen and UC Berkeley scientists shows that they evolved this ability by enlarging their spleen about 50 percent. A genetic analysis links this to upregulated thyroid hormone. This is a unique adaptation to living in a low-oxygen environment, the researchers say.
A rear-ender in which the driver's head slams against the steering wheel or a helmet-to-helmet tussle with an opponent on the football field may increase one's risk for Parkinson's disease if concussion results, say researchers from UCSF and the San Francisco Veterans Affairs Medical Center.
While women are two to four times more likely than men to tear the anterior cruciate ligament (ACL) in their knee, the cause of this injury is no different between the sexes, according to new research from Duke Health.
People who have been diagnosed with a mild concussion, or mild traumatic brain injury, may have a 56 percent increased risk of developing Parkinson's disease, according to a study published in the April 18, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The inactivity of astronauts during spaceflights presents a significant risk to their muscles, says a new study in The Journal of Physiology. Scientists have simulated the impact of 21-day spaceflights on the body, and the impact of low gravity environments such as the moon or Mars.
The University of Virginia neuroscience lab that discovered that the brain connects directly to the immune system now has found evidence that doctors could load up the brain with custom blends of immune cells to battle genetic disorders and neurodegenerative diseases such as Alzheimer's.
A new study at the University of Jyväskylä, Finland reports that autophagosome content is increased by resistance training in previously untrained young men, but this response may be blunted by aging.
A study conducted by QUT's Centre for Accident Research and Road Safety -- Queensland -- has revealed poor road infrastructure is a major factor in cyclist safety, especially during incidents involving them being overtaken by motorists.
A study from researchers at Indiana University has found differences in the brains of athletes who participate in contact sports compared to those who participate in noncontact sports.
Patients with Medicaid in Massachusetts have limited access to reimbursable physical therapy (PT) after anterior cruciate ligament (ACL) reconstruction surgery, according to a new study.
