MIT: Oceans are a major gene swap-meet for plankton

...an important part of the food chain in the oceans, supply some of the oxygen we breathe, and even play a role in modulating climate. So it's very important that we understand what regulates their populations. And now genetic diversity seems to be an important factor," said Chisholm, who holds appointments i...

University of Utah to help build bionic arm

...ears. Fraunhofer IZM will help develop a system to supply electrical power wirelessly to the electrode array. It also will combine the electrode array with signal processors and amplifiers so that the implanted device ?less than one-third inch on a side ?can relay signals back and forth wirelessly between t...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...amage to the heart muscle as a result of the blood supply to the heart muscle being cut off during the heart attack. The damaged muscle inhibits the heart's overall ability to pump blood, leading to heart failure," said Rush principal investigator cardiologist Dr. Gary Schaer, head of the Rush Cardiac Cath...

For a successful pregnancy to occur, stromal cells of the uterus must be transformed into decidual cells, which secrete nutrients that allow the embryo to survive until it plugs into the blood supply. C/EBPb is necessary for d...

Basic research leads to a novel cancer therapy

...vered that by interrupting the oxygen and nutrient supply to tumour cells, it is possible to inhibit cancer development. The Max Planck scientists showed that tumour tissue just a few cubic millimetres in size can create vascular endothelial growth factor (VEGF), which triggers blood vessel development. Ul...
