By Amplifying Cell Death Signals, Scientists Make Precancerous Cells Self-destruct
On the cellular level, death signals can actually be life saving -- by killing off abnormally dividing cells before they turn cancerous. Now, Rockefeller University researchers have found a way to amplify these signals by turning a life affirming protein into a killer. The findings not only mark a breakthrough in the field but also open the door to a new line of drugs for cancer therapeutics.

Old Growth Giants Limited By Water-pulling Ability
The Douglas-fir, state tree of Oregon, towering king of old-growth forests and one of the tallest tree species on Earth, finally stops growing taller because it just can't pull water any higher, a new study concludes.

Dying Frogs Sign Of A Biodiversity Crisis
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. The researchers argue that substantial die-offs of amphibians and other plant and animal species add up to a new mass extinction facing the planet.

Images For 3-D Video Games Without High Price Tags Or Stretch Marks From UC San Diego
The images of rocks, clouds, marble and other textures that serve as background images and details for 3-D video games are often hand painted and thus costly to generate. A breakthrough from a computer science undergraduate now offers video game developers the possibility of high quality yet lightweight images for 3-D video games that are generated "on the fly," and are free of stretch marks, flickering and other artifacts.

Potatoes May Hold Key To Alzheimer's Treatment
A virus that commonly infects potatoes bears a striking resemblance to one of the key proteins implicated in Alzheimer's disease, and researchers have used that to develop antibodies that may slow or prevent the onset of AD.

Synthetic Biology Is Bearing Fruit: Blockers Against Blockers
Synthetic Biology is bearing fruit: the tuberculosis pathogen can be fooled by a widely used food additive. The WHO records around nine million new cases of the disease each year, and about 50 million people are infected with a strain of Mycobacterium tuberculosis that is resistant to the antibiotics Isoniazid and Rifampicin.

English Health-care System Failing To Provide Basic Care, Shows Major Survey
The NHS and private health care are not providing good enough basic care to a large portion of the population in England, especially older and frailer people, according to a new study. Overall, only 62 percent of the care recommended for older adults is actually received, conclude the authors.
