Glow-in-the-dark zebrafish at UH hold keys to biological clocks

Using genetically altered zebrafish that glow in the dark, University of Houston researchers have found new tools that shed light upon biological clock cycles. Gregory M. Cahill, associate professor of biology and biochemistry at UH, and Maki Kaneko, a fellow UH researcher who is now at the University of California-San Diego, presented their findings in a paper titled "Light-dependent Dev...

Scientists find viruses can't stick to sea bugs in the dark

Blue-green algae, or cyanobacteria, in the seas are as vital to the survival of life on earth as the oxygen producing plants are on land. But marine bacteria are attacked by viruses, which can seriously affect their life-sustaining abilities but mow a researcher at the University of Warwick has discovered that these viruses don't work in the dark, according to research presented today (Monday, 04...

Expanding forests darken the outlook for butterflies, study shows

Changing environmental conditions in the Canadian Rockies are stifling the mating choices of butterflies in the region, say University of Alberta researchers. Smaller and less abundant alpine meadows--largely the result of human activities--are diminishing the alpine butterfly gene pool, creating a pattern that could lead to the butterflies being less able to survive, said Dr. Jens Roland,...

Opiate cocktail may spare cells from morphine's dark side

Although morphine is well known as a highly effective analgesic, its clinical utility is severely limited by the development of drug tolerance, the requirement for increasing doses to maintain analgesic effect, and the development of physical dependence. In the June 7 issue of Current Biology, researchers report a new study showing that the administration of a drug cocktail containing morphine al...

New clues to the dark side of a key anti-tumor guardian

Although researchers over recent years have established a foothold in understanding how p53 protects against cancer, the mechanisms by which it might contribute to aging and lifespan are not well studied. In work reported this week, researchers studying p53 function in fruit flies show new evidence that despite the protective role of p53 as a guardian against tumor formation, normal levels of p53...

Dark skin protects

An Australian researcher suggests dark skin could be better than white at fending off fungi and bacteria. A paper by Sydney-based biologist James Mackintosh says it could explain why dark skin evolved in humans and animals living in tropical environments. A popular theory on why darker skin prevailed in some areas and lighter skin in others, is that// the extra melanin in darker skin p...

Fear of the dark could be more than just fear!

Researchers have found that children who complain that they are afraid of the dark, may have night blindness, a diagnosis that can be easily missed. They said that parents who do not monitor their children's night time behaviours and who do not have a family history of visual problems may miss the rare form of the disease called stationary night// blindness. A child with no visual problem...
