Discovery could explain why light keeps us awake and may lead to new treatments for disorders such as jet-lag and SAD.
Researchers from Imperial College London, Johns Hopkins University, USA and Brown University, USA have discovered that melanopsin, a recently identified protein, plays a key role in a completely new light detection system in the eye.
Professor Russell Foster, from Imperial College London at the Charing Cross Hospital comments: “It had long been assumed that
A Mayo Clinic investigation of Interleukin-6, a hormone inside cells often considered a “bad actor” of the immune system because of its association with inflammation injuries and malignant diseases, shows that it also plays a therapeutic role in mice: it protects brain cells.
Interleukin-6 — called IL-6 for short by researchers — may, in fact, be a “white knight” for mouse brain cells, or neurons, as brain cells also are called. These results, while early, may be promising for humans as w
Further underscoring the limitations of cholesterol screening in assessing a patient’s risk for heart disease, a new study by UC Davis physicians is the first to conclusively link C-reactive proteins (CRP) to formation of blood clots, a major cause of heart attacks, strokes and other vascular disease. Until now, CRP had been recognized mainly as a risk marker of heart disease. The study appears in the Jan. 25 print edition of the journal Circulation, a publication of the American Heart Association,
Researchers are reporting progress in understanding whether a second light-sensing pathway in mammals indeed contributes to the detection of ambient light for controlling body functions.
In an article published in the January 10, 2003, issue of the journal Science, the researchers report that the molecule melanopsin is necessary in order for the pupil to constrict properly in response to light, a function termed the pupillary light reflex.

Innovative tests trigger clean up efforts at popular California beach
A UC Irvine-led study has proved instrumental for significantly improving the quality of beach water at a popular California tourist destination. The same study also provides the blueprint for assisting similar beachside communities with an innovative approach for pinpointing the causes of water pollution.
The research was headed by UCI environmental engineer Stanley Grant and USC microbiologist Jed Fuhrman
Eating your own brain may not sound like a sensible approach to prolonging your life, but researchers at the University of Rochester have discovered that some single-celled organisms essentially do just that to keep themselves healthy. The findings are published in this months issue of Molecular Biology of the Cell.
David Goldfarb, professor of biology at the University of Rochester, studied the yeast Saccharomyces cerevisiae and found that contrary to what biologists have believed, th
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
