Isotopic analysis of a bone from the 40,000 year old Tianyuan Cave skeleton (Zhoukoudian region of China near Beijing) by an international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, the Graduate University of Chinese Academy of Sciences and the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, the University of British Columbia in Vancouver and Washington University in Saint Louis has shown that this individual was a regular fish eater.

NEW YORK (JULY 7, 2009) -- The Wildlife Conservation Society (WCS) announced today the discovery of a new monkey in a remote region of the Amazon in Brazil.
The monkey is related to saddleback tamarins, which include several species of monkeys known for their distinctively marked backs. The newly described distinct subspecies was first seen by scientists on a 2007 expedition into the state of Amazonas in northwestern Brazil.
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions.
As the world celebrates Charles Darwin, who was born 200 years ago, physicists can be forgiven a certain jealousy at the spotlight being placed on his profound legacy. But physicists have in fact had a huge impact on biology – no more so than in helping to discover the structure of DNA and in developing medical-imaging techniques like MRI. The July issue of Physics World marks those achievements and examines at some of the ways in which current ideas in physics are still changing biology.
Giving a local anaesthetic during a Caesarean section helps manage pain after the operation and can reduce consumption of painkillers, according to Cochrane Researchers. The researchers recommend local anaesthetics as part of integrated pain management strategies for Caesarean section operations, provided that consideration is given to the cost.
Though New Orleans residents were told to evacuate days before the arrival of Hurricane Katrina, no one could have predicted the real extent of the devastation.
Now researchers from Tel Aviv University say they have found a novel and reliable way to help predict the intensity of the next big flood, using common cell phone towers across the United States. Their model, which analyzes cell phone signals, adds a critical component to weather forecasting never before available.
Leiden theoretical physicists have now, for the first time, used string theory to describe a physical phenomenon. Their discovery has been reported in Science Express, and is the first time that a calculation based on string theory has been published in Science,
'This is superb. I have never experienced such euphoria.' Jan Zaanen says enthusiastically. Together with Mihailo Cubrovic and Koenraad Schalm, he has successfully managed to shed light on a previously unexplained natural phenomenon using the mathematics of string theory.
Planck is equipped with a passive cooling system that brings its temperature down to about -230°C by radiating heat into space. Three active coolers take over from there, and bring the temperature down further to an amazing low of -273.05°C, only 0.1°C above absolute zero - the coldest temperature theoretically possible in our Universe.Such low temperatures are necessary for Planck’s detectors to study the Cosmic Microwave Background (CMB), the first light released by the universe only 380 000 yrs after the Big Bang, by measuring its temperature across the sky.
MINNEAPOLIS / ST. PAUL (July 1, 2009) — University of Minnesota Medical School researcher Michael Mauer, M.D., has found a treatment that significantly slows the progression of eye injury in people with type 1 diabetes, a common complication caused by this disease. By administering an antihypertensive, medication commonly prescribed to treat high blood pressure, Mauer and colleagues were able to slow progression of diabetic eye damage in more than 65 percent of participants involved in the study.
Researchers from the National Oceanography Centre, Southampton, have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant – the king crab. The results, published this week in the Journal of Biogeography, reveal temperature as a driving force behind the speciation and radiation of a major seafloor predator; globally, and over tens of millions of years of Earth's history.

Palo Alto, CA— When glaciers advanced over much of the Earth's surface during the last ice age, what kept the planet from freezing over entirely? This has been a puzzle to climate scientists because leading models have indicated that over the past 24 million years geological conditions should have caused carbon dioxide levels in the atmosphere to plummet, possibly leading to runaway "icehouse" conditions. Now researchers writing in the July 2, 2009, Nature report on the missing piece of the puzzle – plants.
New Haven, Conn. — Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers at Yale University, the Carnegie Institution of Washington and the University of Sheffield now show that land plants saved the Earth from a deep frozen fate by buffering the removal of atmospheric CO2 over the past 24 million years.
Pittsburgh, PA…According to new research published online in the Proceedings of the Royal Society B (Biological Sciences) on July 1, 2009, a new fossil primate from Myanmar (previously known as Burma) suggests that the common ancestor of humans, monkeys and apes evolved from primates in Asia, not Africa as many researchers believe.
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. The new processor is far from conventional, however, in that it uses the potent power of quantum mechanics to bring the dream of quantum computing a small but significant step closer to reality.
