UVA has discovered an unknown biological process that controls the production of vital cells that carry oxygen throughout the body. The discovery could help doctors develop new treatments for anemias that affect millions of people.
In a nationally representative study, researchers found considerable variation in the rates of hip fractures across US nursing home facilities. The Journal of the American Geriatrics Society study identified a number of modifiable facility-level characteristics that might be addressed, but the majority of the variation in the risk of hip fracture remained unexplained.
Researchers have, for the first time, used a material's persistent photoconductivity to stimulate neurotype cells. The technique, which is relatively simple, should facilitate future research on using charge to influence cellular behavior.
One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals that they all could be shot out into space after cosmic rays are accelerated by powerful jets from supermassive black holes. The model may set a new milestone on the path toward solving the half-century-old enigma of the origin of the highest-energy particles in the universe.
Localized gene delivery to diseased joints to achieve sustained drug production at the site of osteoarthritis or rheumatoid arthritis is gaining momentum, with clinical trials underway in the US and the first arthritis gene therapy recently approved in Korea.
When families don't have stable housing, their risk of struggling with poor health outcomes and material hardships, such as food insecurity, increases, according to a new study from Children's HealthWatch. Researchers surveyed over 22,000 families and found that one third of low-income renters were housing unstable, which was associated with negative impacts on their health.
"There are simply are not enough physicians comfortable with treating transgender patients," according to Joshua D. Safer, MD, FACP, associate professor of medicine at Boston University School of Medicine (BUSM). To begin to address this issue, BUSM has created a medical school elective that combines the standard approach of teaching about transgender medical topics with sensitivity and appropriate terminology with evidence-based hands-on patient care.
Young men who have sex with men (MSM) are at much higher risk of HIV infection compared to their peers, but a new study led by a Boston University School of Public Health (BUSPH) researcher suggests young MSM are less likely to receive school-based HIV education than young men who only have sex with women.
PTB physicists have developed a frequency-doubling unit for transportable, optical atomic clock that will even continue to operate when it has been shaken at three times the Earth's gravitational acceleration. The results have been published in the current issue of the Review of Scientific Instruments.
By identifying why skin immunity declines in old age, a UCL-led research team has found that an anti-inflammatory pill could help make vaccines more effective for elderly people. The study, published today in The Journal of Allergy and Clinical Immunology, found that an excessive inflammation reaction in older people can obstruct the immune system.
