Colleagues, friends gather to commemorate Nobel Laureate Axelrod

... early 1960's on brain chemistry, which has become fundamental to our understanding of depression and anxiety disorders. His research described the "re-uptake" mechanism in brain cells, which regulates the levels of neurotransmitters available for communication between neurons (in fact, Dr. Axelrod coined the ph...

To stop evolution: New way of fighting antibiotic resistance demonstrated by Scripps scientists

...Taxes Anymore This research raises fundamental questions about evolution. Biologists have often thought about evolution in the same way many think about death and taxes -- something inevitable. But Romesberg is a chemist, and he found himself asking not only how, but why evolution happens. ...

Same fold in viral shells point to common ancestry

...id. Researchers are studying the T4 virus for many fundamental biological studies, some of which might be used to create new vaccines to fight viral infections in humans. "Many people have talked about using T4 or other bacteria viruses as antibiotics," Fokine said. "Although we are conducting research regarding...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

...a from the 20th century. "Finding nonlinearity is fundamental for understanding and managing changes in ecosystems," said Lucas of the Biological Oceanography Curricular Group at Scripps. "In the North Pacific ecosystem, nonlinearity means that different sets of biological growth rules will apply in each differ...

The ultimate spa: embryonic body wash controls left-right development

...an independent nonprofit organization dedicated to fundamental discoveries in the life sciences, the improvement of human health and the training of future generations of researchers. Jonas Salk, M.D., whose polio vaccine all but eradicated the crippling disease poliomyelitis in 1955, opened the Institute in 196...

Researchers develop assay that could be applied to drug screening

... is clathrin mediated endocytosis (CME). CME is of fundamental importance for many cellular activities including receptor down-regulation, nutrient uptake and maintenance of signal transmission across nerve cell junctions. Mis-regulation of CME has been implicated in some types of cancer and neuro-degenerative d...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...urprise to the researchers. They set out to answer fundamental questions about the small number of brain neurons that can be replaced when they die: Are these cells similar to other neurons that are not replaced in adult life? Or, in terms of which genes are "turned on," are they marked as transient? Nottebohm'...

'Wet' electrons provide easiest way to transport charge, Pitt researchers find

...Petek calls similar to a wet electron system "on a fundamental level." Petek plans to continue research on the properties of other oxide materials. In their paper, the researchers note that conditions exist to support similar states on all oxide surfaces in contact with water or with a humid atmosphere. The pape...

Retina adapts to light changes by rewiring itself

...inner plexiform layer is believed to contribute to fundamental features of vision, such as sensitivity to light, temporal processing of motion, and detection of contrast. The new study by Jozsef Vigh, Ph.D., postdoctoral fellow at the Vollum and lead investigator, examined the retinas of goldfish, which contain ...

ORNL nanoscience center 'jump starts' medical compound device

...is ideas for nanotechnology applications. "I had a fundamental interest in nanotechnology for many years. Once I found an application and learned more about it, I became really intrigued, but the real launching pad for me deciding to do this was the CNMS facility being built here," Matteo said. "Certainly, with...

Winners of first Trieste Science Prize announced

Trieste, Italy. An Indian scientist, who has made fundamental contributions to our understanding of the physical forces that turn liquids into solids, and a Brazilian biologist, who has advanced our knowledge of how enzymes reduce high blood pressure and lessen the sensation of pain, are the first two recipient...

Barring some fundamental misunderstanding about the nature of DNA decay, he says it is highly unlikely viable DNA will be recovered from 150 to 200 million year old Jurassic age samples. Currently, the theoretical limit is about 100,000 years old for samples preserved in t...
