Advance moves stem cell research forward
LA JOLLA, Calif., April 24 (UPI) -- Scientists in California say they've made an important step forward in the race to make reprogrammed stem cells without problematic genes.
Naturally Occurring Compounds Selectively Deplete Mutant P53 In Tumor Cells
Researchers have demonstrated that naturally-occurring compounds can selectively deplete mutant p53 and restore "wild type" function to p53 in a variety of tumor cells.
Vitamin D actually a hormone
New research suggests that vitamin D isn't really a vitamin at all - it's a hormone made inside the body without any help from the sun.
Discovering Genes That Protect Against Aging
Scientists have developed a new method to help researchers identify genes that can help protect the body during the aging process.
Gene Variants Associated With The Most Common Adult Leukemia Confirmed
Researchers have found that patients with chronic lymphocytic leukemia are more likely to have similar DNA changes or variants in up to six genes, compared to people who do not...
Ecologists Put Price Tag On Invasive Species
Invasive species can disrupt natural and human-made ecosystems, throwing food webs out of balance and damaging the services they provide to people. Now scientists have begun to put a price...
Secret To Night Vision Found In DNA's Unconventional 'Architecture'
Researchers have discovered an important element for making night vision possible in nocturnal mammals: the DNA within the photoreceptor rod cells responsible for low light vision is packaged in a...
Grouping muscles to make controlling limbs easier
With more than 30 muscles in your arm, controlling movement - whether it's grasping a glass or throwing a baseball - is a complex task that potentially takes into account...
Great Wall longer than previously thought
BEIJING, April 20 (UPI) -- China's historic Great Wall is about 1,550 miles longer than previously thought, a government survey reveals.
Humanized Mouse Infected With HIV Vaginally And Rectally Allows Testing
A "humanized mouse" has allowed physician-scientists to conduct HIV/AIDS studies that would have been impossible without such a small animal model of HIV infection. The virus only infects humans and...
A Conversation With Richard Wrangham: From Studying Chimps, a Theory on Cooking
Richard Wrangham has spent four decades observing wild chimpanzees in Africa to see what their behavior might tell us about prehistoric humans.
Recipes for Health: Risottos Perfect for Spring Vegetables
Tender spring vegetables appear only fleetingly at the market. Grab them while you can, and use the limited quantities to in these easy risottos.

Plant Gene Mapping May Lead To Better Biofuel Production
By creating a "family tree" of genes expressed in one form of woody plant and a less woody, herbaceous species, scientists have uncovered clues that may help them engineer plants...
Breaking The Animal Kingdom's Color Code
Charles Darwin was fascinated by the colors of animals. Ever since, researchers have wondered why most animals that have an anti-predatory defense, such as a sting or poison, tend to...
Breakfast choices impact hunger and calorie consumption throughout day
New Orleans (April 20, 2009) - New studies presented this week at Experimental Biology 2009 enhance the growing body of evidence supporting the nutritional benefits of eggs. Research presented at...
Time Record Of Marine Species Formation In The Baltic Sea
Four years ago researchers discovered a new species of seaweed in the Baltic Sea. New studies reveal that this species may have formed only 400 years ago, making this seaweed...

How will plant cells that live in the oceans and serve as the basic food supply for many of the world's sea creatures react to climate change? Biologists came one...
Closing In On Goat Scrapie
Goats are tough, spirited animals, but they're no match for scrapie, a form of transmissible spongiform encephalopathy. Now, with a "helping hand" from science, the animals' plight could take a...
