Same-Sex Mating Discovered in a Toxic Fungus

...se of any disease, the better positioned we are to develop cost-effective diagnostic or therapeutic interventions." The fungal strategy may also contribute to scientists' general understanding of the conditions that favor evolutionary transitions between self-fertilization and sexual reproduction among unre...

Potential Drug Target For Treating Cocaine Abuse Found

...ffects of cocaine and could potentially be used to develop drug therapy for cocaine abuse, new research shows...this breakthrough shows that it may be possible to develop drugs that block cocaine's stimulating effects, and perhaps its power to addict, Nestler says. Rese...

Genetic defects give the immune system the green light to attack the pancreas

...lls form, it is not uncommon for a few to randomly develop with the potential ability to attack the body’s own cells,?said Dr. Holler. “That’s when a safeguard mechanism normally kicks in to eliminate these errant T-cells. Our team found the genetic regions that govern this safeguard.?/p> What if the saf...

Study reveals new technique for fingerprinting environmental samples

...mediating contaminated environments. This may well develop environmental ecology into a fully quantitative science." Dubbed Environmental Genomic Tags, or EGTs, these indicators capture a DNA profile of a particular niche and reflect the presence and levels of nutrients, pollutants, and other environmental ...

Researchers unlock mechanism creating jigsaw puzzle-like plant cells

... allows cells in thin structures such as leaves to develop in a jigsaw-like pattern, providing the leaf a surprising degree of strength. The findings were published in today's edition of the journal Cell. Zhenbiao Yang, a professor of plant cell biology at the UCR's Center for Plant Cell Biology and Institu...

Scientists journey to southern Africa to unravel the secret world of elephant communication

New tumor-suppressor gene discovered

...rally occurring genetic defect that caused them to develop the tumors. He used genetic-mapping techniques to study the mutant fly's chromosomes and identified a short segment of DNA on which a mutant gene was most likely to occur. "Genetic techniques helped us to narrow our search for this fly's mutation to ...

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

...author of the study. "The finding will allow us to develop a simple model to study fragile sites in a way that can't be done in more complex organisms." The findings suggest that mammalian and yeast fragile sites may have common features, an indication that a common mechanism may underlie their occurrence, ...

The evolutionary triumph of flower power

...s were so positive that the researchers went on to develop the evolutionary emotional niche model. In the first study, flowers were tested against other gift stimuli, such as a fruit and sweets basket and a large decorative candle. Of the 147 women tested, all those who received flowers responded with a smi...

Maine Researchers Find Exceptions to Old Rules of Genetic Inheritance

... in these phenomena. They used this information to develop transgenic mice that carried the candidate region derived from the wild haplotype. When the transgenic region segregated with the t haplotype, the researchers noted that males carrying two copies of the t haplotype plus the transgenic region were fe...

...hrenheit) since 1950. As showers and thunderstorms develop in the rising air above the warming ocean, says Hurrell, they help lead to sinking air and drought in a surrounding ring that includes southern Africa. "In our models, the Indian Ocean shows very clear and dramatic warming into the future, which mea...

Plant Sacrifices Cells to Fight Invaders

... (NSF) Plant Genome Research program, had to first develop the gene-silencing technique to adequately inactivate the plant genes. The new technique was a success for the field of plant research and is currently being used by several research groups. NSF's Jane Silverthorne said, "This is a great example of h...
