World's top theoretical physicists converge to consider 'future of physics'

...ade of the only material for such purpose that can resist the weathering of the outdoor environment--Vermont slate. Next to those real slate blackboards are niches for chalk and erasers. The idea, of course, is that the physicists can continue to work via their preferred medium--the blackboard--in the cou...

ASPB opposes proposed ban of GMOs in Humboldt county ballot measure M

...enetically engineered plants that more effectively resist pests have also led to improved crop yields. Furthermore, there are instances in which genetic engineering can produce healthier and safer foods than can be accomplished using traditional plant breeding technologies. Researchers based i...

Passage of GMO ban in San Luis Obispo would encourage use of harsh pesticides

Calorie restriction leads to some brain benefits but not others in mice

... calorie restriction helps animals live longer and resist some effects of aging, scientists still do not know why. One theory suggests a restrictive diet decreases the effect of free radical damage. Free radicals are chemically reactive molecules produced either as byproducts of the body's natural processe...

With the new sensor and control system in place, NOx emissions could be remediated with catalysts, traps or selective catalytic reduction. The pr...

...y touch. His work on how shelled animals evolve to resist predators or attack their prey led him initially to questions about the "arms race" between groups of humans, and then to a wider perspective on how societies change and grow. "Whether our field is natural history, human history, evolutionary bi...

Acid-resistant bug doesn't give in to alcohol either

... "Important enzymes in this bug resist acid in a way almost all organisms cannot, and we're trying to answer the question: 'How is this enzyme different?'" That answer, Kappock said, could reveal many new important insights.Kappock discussed his research at th...

Heart protein could be used to repair damage caused by heart attack

The next step, Dr. Srivastava said, is to determine the most effective dose, the optimal time to administer Thymosin beta-4 and how long after an attack the protein can be given to be effective...

Differences in gene usage dramatically change bacteria's 'lifestyles'

...D into E. coli, the bacteria gained the ability to resist polymyxin B in low magnesium environments. Based on data still to be published, Groisman suspects that many other aspects of microbial lifestyle are affected by differences in regulation of identical genes. He notes that the idea of different organis...

USC-led team of scientists recreates DNA-mending pathway in test-tube

If we could inhibit the pathway regionally in or around the tumor, we could really make radiation dramatically more effective." In order for the team to reconstitute the NHEJ pathway, which is found in all cells that are evolutionarily...

Scientists uncover clues to the mystery of 'gene deserts'

... that the stable desert regions, which are able to resist genomic rearrangement and fend off infringement by repetitive segments of junk DNA, are home to a surprisingly large fraction of the genome's non-coding regulatory elements. "There are many indications that stable gene deserts represent treasu...

DNA breaks and genomic instability: Broken ends stick together

...ry after a double-strand break is to help DNA ends resist the pulling forces of the mitotic spindle. This keeps the broken ends together as the DNA is repaired and leads to proper chromosome segregation in mitosis....

Loss of fruit fly retina protein delays blinding light damage

...ight-detecting protein rhodopsin was engineered to resist destruction retained their vision twice as long as normal flies, although over time they developed blindness due to delayed decay of rhodopsin. The researchers measured vision damage indirectly by measuring loss of the electrical signals normally ini...

University of Pittsburgh receives award to study new theory of breast cancer development

According to Dr. Donnenberg, this very knowledge may provide a promising new paradigm to understanding the growth and spread of cancer. The project will examine a subset of highly malign...

Enzyme allows B cells to resist death, leading to leukemia
