Some Brain Cells 'Change Channels' To Fine-tune The Message

...ve. "Calcium turns some processes on, and it turns others off," he says. "My personal belief is that the cells might be doing more than just protecting themselves by keeping calcium out." In some cases, protection might be enough of a goal. In people with Lou Gehrig's disease, or amyotrophic lateral sclero...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...ds and may be able to conceive on their own, while others will become infertile. Egg cryopreservation could be insurance for those women at highest risk of fertility problems after cancer treatment. When a woman wishes to become pregnant, the vitrified eggs would be warmed and then fertilized with male spe...

Different microarray systems more alike than previously thought

... there is a large lab effect that accounts for why others thought comparisons revealed inconsistencies." "This is good news for many people," said Forrest Spencer, Ph.D., associate professor at Johns Hopkins' McKusick-Nathans Institute of Genetic Medicine. "Given appropriate and careful analysis, it should...

Cerebral navigation: How do nerve fibers know what direction to grow in?

...xons to extend and grow in a particular direction; others are inhibitory, making the axon turn away or stop growing. In two papers in the April 21 Neuron, researchers from Children's Hospital Boston reveal important insights into how inhibitory cues affect the growth cone, and identify possible targets wit...

Insight into DNA's 'weakest links' may yield clues to cancer biology

..., resulting when broken chromosomes re-joined with others to form novel arrangements, the researchers reported. Through further examination of breakpoints in a small region of one chromosome, the researchers found that the fragile sites occurred at locations along the DNA containing "retrotransposons" call...

The evolutionary triumph of flower power

... few days later, some only on the second round and others after the study. Everyone also received a decorative booklet for note-taking. As might be predicted, the one-bouquet group was happier ?more smiles and less observed depression ?than those left for last; the two-bouquet folks were happier still. The...

Double triumph in stem cell quest

To help define areas and ecological parameters critical to the survival of this remnant population of right whales, habitat use was investigated by scientists at the NOAA National Marine Fisheries Service's, National Mari...

Agilent Technologies releases probe sequence, annotation information for all its commercial gene expression microarrays

Enterprising furriers imported American mink into Europe, where the animals escaped from captivity and spread prolifically. European mink ha...

Scientists discover that three overlapping signals in embryo help get the backbone right

"Redundancy is designed to make the embryo robust, so as to avoid b...

Road salt affects mitigation wetlands

Sacrificing one wetland for the sake of five others may be the way to go when planning constructed wetlands to replace those destroyed during road building, but a Penn State Erie biologist is monitoring the salinity of the wetlands to see how the salt affects animals and insects. "I am currently doin...

Discovery clarifies role of peptide in biological clock

But when Herzog and Aton added VIP to the mice cells, the synchronicity was restored, showing that VIP couples pacemaker cells and drives rhythms in slave cells. "VIP between SCN neurons is like a rub...
