Don't stand so close to me: A new view on how species coexist
...living together in communities don't rub shoulders too
closely because evolution has caused them to compromise on key life measures, say ecologists at Imperial College London and Royal Holloway, University of London, writing in the journal Science today (1 October). The researchers suggest a new basis fo...
How roots control plant shoots
... growing, presumably when water is scarce, soil is too
compacted or other conditions are bad. While roots obviously carry food and water to the leaves, the new findings help show how roots also send chemical signals that control whether or not leaves grow. How leaves grow is a crucial matter given that...

Experts present new research on hot topics in aging at GSA's annual meeting in Washington, DC

...umber of areas and addresses the problem of having too
much information for trained personnel to analyze. Consequently, much of the staggering collection of data is not effectively utilized, said ORNL's Budhu Bhaduri, co-principal investigator for the project. With the ORNL system, security experts would...
FSU scientist links iron imbalance to Parkinson's disease
...ed vitamins, because absent a diagnosed deficiency too
much of a good thing can be bad. Dietary iron imbalances either way spell trouble for healthy cells, triggering a chain of cellular events in the brain that increases the odds of developing Parkinson's disease, a degenerative condition affecting move...
Effort to control trade in great white sharks gets teeth from international community

Channel protein converts vibrations to electrical signal
...in, cadherin 23, suggested that their structure is too
rigid for this role. "Part of the TRPA1 molecule is a long chain of ankryin repeats, and we think that the ankryin repeats actually form the elastic element that had been defined biophysically," Corey said. He plans further experiments to test this p...
Time-lapse movies show brain cells move like a two-stroke engine

NHGRI seeks next generation of sequencing technologies
...A's" A nanometer is one-billionth of a meter, much too
small to be seen with a conventional lab microscope. Most groups developing nanopores (holes about 2 nm in diameter) as DNA sequence transducers propose to detect an electrical, or ionic, signal from individual DNA molecules. This group will pursue a...
Surgeon General's report underscores the importance of new thinking on bone health

many people have not adequately considered the repercussions of their diets and lifestyles on their bone health. We believe today's report is an important tool to spur healthcare professionals, advocates and private industries on in our efforts to fi...
Normal cells in tumors may aid cancer growth

soon to say how genetic damage to stromal cells might influence tumor growth. However, stromal cells can produce growth factors and other substances that can influence the behavior of cancer cells. The loss of chromosome regions may result in ...

UCLA scientists discover new way to fix defective gene
...of A-T patients, PTCs halt the copying of proteins too
early, resulting in shortened and unstable ATM proteins. "Unstable proteins create abnormal cells that can't function properly, producing all of the neurological and immune problems that afflict A-T patients," said Lai, the study's first author. La...

Early life stress can inhibit development of brain-cell communication zones, UCI study finds
...Thus, we had two lines of evidence suggesting that too
much CRH in the developing hippocampus might lead to the abnormal dendrites," said Baram, a pediatric neurologist and neuroscientist. "The good news is that we were able to prevent this effect in the lab." To do this, the researchers used a selectiv...
