Scratch no more: Gene for itch sensation discovered

...y, scientists regarded itch as just a less intense version of the pain sensation. As a result, research on itching has been somewhat neglected. "Many genes have been identified in the pain pathway," says Chen, associate professor of anesthesiology, psychiatry and molecular biology and pharmacology. "But itch...

Cellular message movement captured on video

...cientists have captured on video the intracellular version of a postal delivery service. Reporting in the journal Biochemical and Biophysical Research Communications (BBRC), bioengineering researchers at UC San Diego published videos of a key message-carrying protein called paxillin moving abruptly from hubs...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...ed in human eggs, says Dr. Emmi, who believes some version of vitrification likely offers a better option for ovarian tissue and eggs. In fact, many in vitro fertilization programs, including the one she directs at MCG Health System, are moving toward vitrification, which also seems to work faster, better an...

Newly discovered antibody may be body's natural defense against Alzheimer's

...entists were able to measure and extract the human version of anti-oligomer antibodies from IVIG and then demonstrate that these antibodies are present in the blood of normal individuals. The basis for the selective recognition of oligomers by these antibodies appears to be their capacity to recognize t...

In a paper published June 11 in the online version of Proceedings of the National Academy of Sciences, researchers report the first evidence that a common species of saltwater algae – also known as phytoplankton – can change form to protect itself against attack by predators that have very different ...

Researchers demonstrate way to control tree height

... would fit nicely on a backyard deck. Or a 30-foot version that might be a better fit on urban streets. Or, in fact, just about any height in between. Other changes can also affect foliage shapes or color in very attractive ways, and some might have value in cleaning up environmental pollution. In their s...

Vaccine prevents prion disease in mice

...vaccine could be considered for humans. "The human version of prion disease usually occurs spontaneously and only rarely because of eating contaminated meat," he said. "But if, for example, a more significant outbreak of chronic wasting disease in deer and elk occurs and if it were transmissible to humans, t...

Professor Frazer said this vaccine could be one of the first made locally at the biopharmaceutical production centre, which received $100 million in last night’s Federal Budget....

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...were competing for food, those that did best had a version of the foraging gene that was rarest in a particular population. For example, rovers did better when there were lots of sitters, and sitters did better when there were more rovers. "If you're a rover surrounded by many sitters, then the sitters ar...

Researchers attach genes to minichromosomes in maize

...Science. A minichromosome is an extremely small version of a chromosome, the threadlike linear strand of DNA and associated proteins that carry genes and functions in the transmission of hereditary information. Whereas a chromosome is made of both centromeres and telomeres with much intervening DNA, a min...

As described in the current study, they obtained a single structural scan of hIAPP in less than a second - more than 500 times faster than previously possible. The speed is crucial for trying to understand a dynamic proce...
