The kapok connection -- Study explains rainforest similarities

...gating the role of oceanic dispersal to see if the same is true for other species and for entire plant communities. "This tree has become locally extinct in parts of the Peruvian Amazon as a result of overexploitation for plywood," Dick said. "It might be saved from widespread extinction by continuing ...

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

... Frostbite treatment has remained essentially the same for the past 25 years, according to background information in the article. “Today, traditional therapy consists of tissue rewarming, prolonged watchful waiting and often delayed amputation,” the authors write. “While many other areas of burns, trauma...

Researchers demonstrate way to control tree height

...ears of evolution and can perform more or less the same function in poplar trees,” Strauss said. “The modified trees themselves look pretty much normal, just a lot smaller, and a little more compact or bushy.” Altogether, the researchers used seven distinct kinds of genes and more than 160 different ty...

Weizmann Institute scientists develop a general 'control switch' for protein activity

...l this by giving exact and well-timed doses of the same simple drug. In addition, the method could be used one day in gene therapy. It may be possible to replace damaged proteins that cause severe diseases with genetically engineered proteins, and to control these proteins’ activity levels in a precis...

Fat fish put obesity on the hook

...ers caused obesity in zebrafish by introducing the same type of genetic mutation that causes severe obesity in humans. The genetic change blocks the activity of a receptor, the melanocortin-4 receptor, which is at the heart of a “device” in our brains called the “adipostat.” The adipostat regulates body ...

How 'memory' T cells curb the spread of viruses throughout the body

...ecomes “immune” (protected) from recurrence of the same disease. This is why before vaccines were developed, childhood diseases such as measles and mumps occurred only once in a lifetime. The immunity occurs when the immune system produces cells called lymphocytes that specifically attack and eliminate ...

Human genetic 'deserts' are teeming with significant life

For example, elk in the mountains of Siberia—who subsist alongside tigers, wolves and bears-- responded five times faster to the recordings than did elk in Rocky Mountain National Park (Colorado) where m...

CU study reveals why starling females cheat

... the first study to show that individuals from the same population mate with extra-pair males and gain both direct (like additional helpers) and indirect benefits (like better genes for the offspring), but that they do so in different contexts," said Dustin Rubenstein, a former Cornell graduate student in...

At the same time, the wealth of data brought new challenges in how to manage this avalanche of information. “The whole is definitely greater than the sum of the parts, and to answer questions across the different areas from ecology to chemistry and climate, scie...

New vaccine prevents CMV infection and disease in mice

...s such as chicken pox or herpes simplex – have the same or very similar sequence, structure and function whether in human or mouse viruses, and present a novel target for the host’s T-cells to muster forces and attack the virus. Secondly, the vaccine also contains a “boost” from an inactivated virus, whic...

The findings may have applications in treating post-traumatic stress disorder, where getting a patient to learn that a once-threatening situation no l...
