Stem cell study finds malfunctioning brain cells in patients who were diagnosed before age 50; researchers test potential new treatment. People who develop Parkinson’s disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially might help correct these disease processes.

Parkinson’s occurs when brain neurons that make dopamine, a substance that helps coordinate muscle movement, become impaired or die...

The damage visible and infrared light can do to our skin has been revealed for the first time in new research by scientists at Newcastle University, UK.

The detrimental effects of exposure to the sun’s rays are well documented, and the main aim of sunscreens is to protect the skin against dangerous ultraviolet radiation (UV).

However, experts at Newcastle University have now scientifically proven that UV rays are not the only type that can penetrate deep into the skin, as visible and infared light can also harm our skin’s cells.

The study, published online today in The FASEB Journal, reveals that the deeper dermal layer of the skin is damaged by UV, visible and infared light and that it may be beneficial for anti-ageing to protect our s...

Regulation of thymic immune development by intestinal microbes in early life. Researchers discover microbes regulate the development of specialized immune cells in the thymus that play a critical role in mucosal tolerance.

Newborns face unique immunological challenges immediately after birth. As they depart a relatively sterile fetal environment, they are abruptly exposed to a multitude of foreign antigens, the major burden of which is in the form of the microbiota newly colonizing the gastrointestinal tract...
