The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report in Current Biology. In a global-scale study, the researchers found some of the first evidence that the health of the deep sea, as measured by the rate of critical ecosystem processes, increases exponentially with the diversity of species living there.

“For the first time, we have demonstrated that deep-sea ecosystem functioning is closely dependent upon the number of species inhabiting the ocean floor,” said Roberto Danovaro of the Polytechnic University of Marche, in Italy. “This shows that we need to preserve biodiversity, and especially deep-sea biodiversity, because otherwise the negative consequences could be unprecedented.

A team of biologists have developed a model mapping the control circuit governing a whole free living organism. This is an important milestone for the new field of systems biology and will allow the researchers to model how the organism adapts over time in response to its environment.

This study marks the first time researchers have accurately predicted a cell’s dynamics at the genome scale (for most of the thousands of components in the cell). The findings, which are based on a study of Halobacterium salinarum, a free-living microbe that lives in hyper-extreme environments, appear in the latest issue of the journal Cell.

The researchers focused on a little studied organism that can survive high salt, radiation, and other stresses that would be deadly to most other organisms.

Over the course of the 20th Century, doctors waged war against infectious bacterial illness with the best new weapon they had: antibiotics.

But the emergence of dangerous, multi-drug resistant strains of tuberculosis and other killer infections means that in the 21st century antibiotics are losing ground against bacterial disease.

Now, researchers from Weill Cornell Medical College in New York City say exciting new molecular targets -- so-called "virulence factors" that bacteria use to thrive once they are in the host -- present an alternative, potent means of stopping TB, leprosy and other bacterial illness.

When it comes to choosing a place to live, male chimpanzees in the wild don’t stray far from home, according to a new report in the Dec. 27th Current Biology, a publication of Cell Press. The researchers found that adult male chimps out on their own tend to follow in their mother’s footsteps, spending their days in the same familiar haunts where they grew up. Male chimpanzees are generally very social, but how they use space when they are alone might be critical to their survival, the researchers said.

“We have found that, like females, male chimpanzees have distinct core areas in which they forage alone and to which they show levels of site fidelity equal to those of females,” said Anne Pusey of the University of Minnesota.

Many studies have been published that link specific “biomarkers” − genes, mRNA or proteins − with an aspect of cancer development or treatment, and the results often appear to be statistically valid, said the lead author of an article in Nature Reviews Cancer. Robert Clarke, Ph.D., D.Sc., is professor of oncology and physiology & biophysics at the Lombardi Comprehensive Cancer Center at GUMC, where he co-directs the Breast Cancer Program.

“But it is not clear that that solution is complete or is necessarily correct. It may be partly right and may be intuitively pleasing because you are getting what you expected to see from an experiment.

WeatherBill (www.weatherbill.com), the world's only online service that allows businesses to protect revenue and control costs from the impact of bad weather, today announced the release of a new study analyzing the impact of weather on film box office revenue. The study found that top ten box office films earn significantly less -- up to a third lower -- on warmer weekends than on average or dry ones. The full study can be downloaded at http://www.weatherbill.com/reports/boxofficeweather and a summary is available at http://www.weatherbill.com/reports/boxofficeweather-summary.

The annual America’s Most Literate Cities ranking, published today in “USA Today,” measures the cultural resources for reading in America’s largest cities. It names Minneapolis, Seattle, St. Paul, Denver, Washington, DC, St. Louis, San Francisco, Atlanta, Pittsburgh, and Boston as the most literate US cities, in that order.

The survey ranks cities (population of 250,000 and above) based on 6 key indicators of literacy: newspaper circulation, number of bookstores, library resources, periodical publishing resources, educational attainment, and internet resources.

This is the fifth year the study has been conducted, and its author, Central Connecticut State University President Dr.
