Taken from a microbe that thrives in the depths of a Yellowstone National Park hot springs pool, a newly discovered enzyme may be the key to transforming industrial bleaching from environmentally problematic to environmentally green.
Chemical engineer Vicki Thompson and biologists William Apel and Kastli Schaller from the U.S. Department of Energys Idaho National Engineering and Environmental Laboratory discovered that the catalase enzyme from a Thermus brockianus microbe flourishes i
Researchers from the National Cancer Institute (NCI) have developed a mouse model of the premature aging syndrome known as Hutchinson-Gilford Progeria Syndrome (HGPS), according to a report appearing in the journal Nature. Researchers hope the mouse model will facilitate a better understanding of the fatal syndrome, as well as provide clues to the normal aging process.
Currently, there is no treatment for progeria, and children with the rare condition usually die of heart disease in their e
New list spotlights most endangered turtles and action plan to save them
The Turtle Conservation Fund (TCF) today released its first-ever list of the Worlds Top 25 Most Endangered Turtles to highlight the survival crisis facing the worlds tortoises and freshwater turtles and to unveil a Global Action Plan to prevent further extinctions. Fully 200 of the 300 living species of tortoises and freshwater turtles are threatened and require conservation action.

We humans are poorly adapted for underwater vision. However, the Moken peoples of south-east Asia manage to collect shells, clams and sea cucumbers using no visual aids when diving to a depth of 3 or 4 metres. Scientists from Lund University in Sweden have now measured the visual acuity of these children and have found that their ability to see well underwater is not a myth: their acuity in this environment is indeed superior to that of European children. The scientists have also found an explanation
A new study from Johns Hopkins researchers shows the multiple anti-HIV drug regimen called highly active antiretroviral therapy (HAART) saves eyesight as well as lives. A second study led by Johns Hopkins researchers finds that among AIDS patients with longstanding vision problems, those who took HAART reported higher overall quality of life.
The Johns Hopkins team reported in the April issue of Archives of Ophthalmology that AIDS patients who received HAART had a 75 percent lower risk of v
When a few weeds appear on your front lawn, you can easily pick them off one by one. But if they start taking over the yard, the picking becomes laborious, and you may need to turn to a chemical weed-killer to hold the invaders in check. After several applications of the herbicide, however, the weeds could become resistant, forcing you to use an even more powerful solution. Meanwhile, the survival of your lawn hangs in the balance.
Like weeds in a lawn, pathogenic fungi and yeasts (single-
