Powerful technique for multiplying adult stem cells may aid therapies

...aces," says Lodish. "They could then discard those bad cells, and only administer the good ones to the patients." But most importantly, these findings aid basic research. "We want to know all sorts of things, like what genes are active in this stem cell, or how this stem cell decides to develop into one...

Cholesterol gets 'thumbs up' for role in digit development

...ete set of 20 digits. Although cholesterol has a bad rap as the sticky, fatty substance responsible for clogging arteries, Vanderbilt University Medical Center researchers recently found that the attachment of cholesterol to an important developmental protein controls the development of fingers and toe...

Honeybee decision-making ability rivals any department committee

How 'hot' emotional brain interferes with 'cool' processing

...'re sad, the world seems sadder and all you see is bad news." "Our aim is to reverse that with drug treatment, so we're using these kinds of studies to determine whether particular antidepressants influence the response of that ventral system. And what is particularly exciting is that this method allows...

Wound monitor 'sniffs out' infections

Using state of the sensors we will be able to detect and diagnose the presence of an infection almost instantaneously." The device will use new hybrid sensor technology with a mobile laboratory-based multi...

How can we protect patients with weakened immune systems from influenza?

The flu is bad enough for healthy people, but the disease can place a special burden on those with weakened immune systems, such as patients on chemotherapy. A five-year, $10.7 million federal grant to The Children's Hospital of Philadelphia will support research t...

Morning grogginess more debilitating than sleep deprivation, according to CU-Boulder study

Following six nights of monitored sleep lasting eight hours per night, the study participants were given a performance test that involved adding randomly generated, two-digit numbers, said Wright. Based on the...

Drug resistance may travel same path as quorum sensing

...hat they think is a communication signal, which is bad news for doctors and their patients. This process, known as multidrug resistance, results in the failure to cure the bacterial disease. Even worse, the resistance is not just to one drug, but many because the pump is now increased and many different...

Paleontologists learn how not to become a fossil

..." Jablonski said. "Small body size turns out to be bad news for preservation in general, and thus deep-sea species are undercaptured." Surprisingly, they found that burrowing clams living within sediments were no more likely to become fossils than similarly sized varieties that lived out in the open. P...
