The kapok connection -- Study explains rainforest similarities

...ng above the forest canopy. Its flowers produce more than 50 gallons of nectar per tree in a season, attracting bats that travel as far as 12 miles between trees and transfer pollen in the process. When the seed pods ripen, they break open to reveal fluffy fibers that are used to stuff pillows and matt...

Mutating the entire genome

Clot-dissolving agent may be beneficial in treatment of severe frostbite

...who did not receive tPA, plus one who received tPA more than 24 hours after injury. Among the six patients who received tPA within 24 hours of injury, six of 59 (10 percent) affected fingers or toes were amputated, compared with 97 of 234 (41 percent) among those who did not receive tPA. “Moreover, no ...

UI anthropologist, colleagues discover remains of earliest giant panda

... -- indicates that the giant panda has evolved for more than three million years as a separate lineage apart from other bears and was adapted to eating bamboo very early in its development. “Pandas are very unique bears -– the only bear species that is known to exist wholly on a vegetarian diet,” says ...

Fat fish put obesity on the hook

...its genetics have been well described. This is one more example of how basic experimental biology – zoology physiology and genetics in this case – can be brought to bear on human problems.” According the U.S. Centers for Disease Control and Prevention, the prevalence of overweight and obesity have ri...

Human genetic 'deserts' are teeming with significant life

... “Our work has shown that the human genome is far more complex than anyone could have imagined, even ten years ago. Understanding these complexities is essential to the development of effective and safe genetic medicine in the future.”...

Researchers identify protein pathway involved in Parkinson disease development

...ter-onset Parkinson disease. "We now know much more about the effect of PINK1 mutations on the mitochondria and how this novel signaling pathway is disrupted in the development of Parkinson disease," says Lian Li, PhD, associate professor of pharmacology in Emory University School of Medicine and rese...

3-D ultrasound scanner provides in-depth view of the brain

...ww.pratt.duke.edu/news/"id=417). To make the probe more suitable for brain scanning, the researchers shrunk it even further, to fit through a 10 millimeter hole in the skull. "The earlier device required a hole bigger than a quarter," Light said. "Now, it's closer to the size of a dime." The brain...

Bacteria called Dehalococcoides ethenogenes, discovered in Ithaca sewage sludge in 1997 by James Gossett, Cornell professor of civil and environmental engineering, and isolated and studied by Stephen Zinder, Co...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have ...
