GAINESVILLE, Fla. — University of Florida researchers are collecting marine invertebrates on the French Polynesian island of Moorea as part of a massive effort to inventory the DNA sequence of every living species there.

The genetic information collected by scientists from UF's Florida Museum of Natural History is part of a whole-system approach that will be used to study ecological processes in depth across the entire island. Moorea's coral reefs in particular are considered crucial indicators of how natural systems respond to climate change.

In spite of their genetic similarity to humans, chimpanzees and great apes have maximum lifespans that rarely exceed 50 years. The difference, explains USC Davis School of Gerontology Professor Caleb Finch, is that as humans evolved genes that enabled them to better adjust to levels of infection and inflammation and to the high cholesterol levels of their meat rich diets.

Blacksburg, Va. ¬¬ –– Although states are not required to report fetal deaths in accident data, between 300 and 1,000 unborn babies die in car accidents each year. This accident fatality rate is about four times the rate for victims between infancy and four years old, said Stefan Duma, head of the Virginia Tech ¬¬- Wake Forest University School of Biomedical Engineering and Science (SBES). http://www.sbes.vt.edu/

"There is no silver bullet to solving these problems," Duma added.

Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests.

Yale University researchers have found very large RNA structures within previously unstudied bacteria that appear crucial to basic biological functions such as helping viruses infect cells or allowing genes to "jump" to different parts of the chromosome.

An important Brandeis study appearing in the December 3 issue of Nature raises the curtain on the hidden lives of proteins at the atomic level. The study reports that for the first time, researchers used x-ray crystallography and nuclear magnetic resonance (NMR) techniques to directly visualize protein structures essential for catalysis at the rare high-energy state. The study also showed how the motions of these rare, or hidden, structures collectively, directly contribute to enzyme catalysis.

PASADENA, Calif.—Researchers from the California Institute of Technology (Caltech) have been able to view in detail, and for the first time, the previously mysterious process by which long chains of a protein called ubiquitin are added by enzymes called ubiquitin ligases to proteins that control the cell cycle. Ubiquitin chains tag target proteins for destruction by protein-degrading complexes in the cell.

A new study reveals how molecular motors that power important subcellular movements can generate cyclical motion. The research, published by Cell Press in the December issue of the Biophysical Journal, opens a new door to understanding motor molecules by using a computer program that faithfully simulates movement of hair-like cellular projections.

Prostate cancer patients who have a prostate-specific antigen (PSA) value of less than or equal to 1.5 at two years after external beam radiation therapy (EBRT) are less likely to have a cancer recurrence and cancer-related death, according to a study in the December 1 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO).

Researchers from the University of Georgia College of Veterinary Medicine have made an "unexpected" dual discovery that could open new avenues for treating Ichthyophthirius multifiliis, or "Ich", a devastating single-celled protozoan parasite that commonly attacks freshwater fish.

With the aid of whole-genome sequencing, researchers found that Ich harbors two apparently symbiotic intracellular bacteria: Bacteroides, which are usually found free-living, and Rickettsia, which are obligate intracellular bacteria. The two bacteria represent new species.

URBANA - For many people "rural" is synonymous with low incomes, limited economic opportunity, and poor schools. However, a recent study at the University of Illinois found that much of rural America is actually prosperous, particularly in the Midwest and Plains.

Waltham, MA—Joseph Balboni loves sports. An avid tennis player and golfer, as well as baseball fan, the 46-year-old insurance agent became increasingly frustrated over time as his eyesight dimmed due to keratoconus, a degenerative eye disorder. Unable to return the tennis ball or see the pitch at Red Sox games, he faced the prospect of a corneal transplant to restore his vision and eye comfort.

WEST LAFAYETTE, Ind. ╤ A Smoky Mountain forest's woodland herb population has shown that climate may play a role in how forest understories recover from logging, according to Purdue University research.

Despite heavy logging in portions of the forest nearly 80 years ago, the distribution of trillium plants on the secondary forest floor was similar to that of undisturbed areas. Michael Jenkins, a Purdue assistant professor of forestry and natural resources, said that contrasts with a study by other researchers of an Oregon forest in which trillium didn't recover after logging.

Scientists may not be able to tell a good book by its cover, but they now can tell the condition of an old book by its smell. In a report in ACS' Analytical Chemistry, a semi-monthly journal, they describe development of a new test that can measure the degradation of old books and precious historical documents based on their smell. The nondestructive "sniff" test could help libraries and museums preserve a range of prized paper-based objects, some of which are degrading rapidly due to advancing age, the scientists say.

SALT LAKE CITY—How do fruit flies get high cholesterol and become obese? The same way as people do – by eating a diet that's too rich in fats.
