Nonhuman Primates Show Sense of Fairness in New Study

Findings shed light on the role of emotion in human economic interactions

In the first experimental demonstration of its kind, researchers led by Sarah Brosnan and Frans de Waal, PhD, at the Yerkes National Primate Research Center of Emory University, and the Living Links Center, have shown nonhuman primates respond negatively to unequal reward distribution, a reaction often seen in humans based on their universal sense of fairness. While researchers have long recognized the sense of

New Approach to Clean Contaminated Aquifers Using Macroemulsion

Environmental engineering researchers have developed a novel two-part approach for cleaning up toxic chlorinated solvents spilled into underground water supplies from former dry cleaning and industrial operations.

The patent-pending technique, which uses a macroemulsion composed of alcohol and food-grade surfactants, simultaneously reduces the density of the pollutant – to keep it from sinking farther into the groundwater – and helps separate it from soil particles so it can be flushed out.

Sandia’s Next-Gen HPC Cluster: Performance Breakthrough Unveiled

Configuration featuring InfiniBand architecture and PCI Express technology delivers performance breakthrough

Sandia National Laboratories today announced at the Intel Developer Forum it will demonstrate an Intel-based next-generation, High Performance Computing (HPC) cluster, the first such cluster to utilize PCI Express visualization systems.

The demonstration will run PCI Express Ethernet and Graphics adapters supplied by ATI on servers supplied by Linux Networx and Celest

’Iron-clad’ evidence for spinning black hole

Telltale X-rays from iron may reveal if black holes are spinning or not, according to astronomers using NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton Observatory. The gas flows and bizarre gravitational effects observed near stellar black holes are similar to those seen around supermassive black holes. Stellar black holes, in effect, are convenient `scale models’ of their much larger cousins.

Black holes come in at least two different sizes. Stellar black holes

How Ocean Plants Evolved: The Shift to Red Phytoplankton

Rutgers marine scientists say phytoplankton changed color 250 million years ago

Green was the dominant color for plants both on land and in the ocean until about 250 million years ago when changes in the ocean’s oxygen content – possibly sparked by a cataclysmic event – helped bring basic ocean plants with a red color to prominence – a status they retain today. That’s the view of a group led by marine scientists from Rutgers, The State University of New Jersey, in a paper, “The Evolu

Astrophysicists Uncover Massive Forming Galaxies in Clusters

A Lawrence Livermore National Laboratory astrophysicist, in collaboration with international researchers, has found evidence for the synchronous formation of massive, luminous elliptical galaxies in young galaxy clusters.

The forming galaxies were detected at sub-millimeter wavelengths. Emission at these wavelengths is due to dust from young stars that is heated by the stars or by active black holes. The galaxies were grouped around high-red shift radio galaxies, the most massive systems kn

Countries find common ground to protect world’s rarest gorilla

The Ministers of the environment from Nigeria and Cameroon have established an agreement to protect the Cross River gorilla, the world’s rarest subspecies of gorilla that totals a mere 280 individuals throughout its entire range, according to the Wildlife Conservation Society (WCS). The Cross River gorilla is only found in Cross River State, Nigeria and western Cameroon and is highly threatened from poaching and habitat fragmentation and loss.

Acidic Runoff Threatens Colorado Ski Areas, Study Finds

The ability of several of Colorado’s prime ski areas to respond to winter drought is threatened by acidic runoff from abandoned mines, according to researchers at the University of Colorado at Boulder and the Northwest Colorado Council of Governments.

Contamination known as acid-rock drainage enters waterways, such as Summit County’s Snake River, that are used for making artificial snow. When the snow melts, the water can run into streams not previously polluted, further spreading

Ancient Relatives of Algae Yield New Insights into Role of CO<sub>2</sub> in Earth&#146;s Early Atmosphere

Awareness of the global warming effects of carbon dioxide (CO2) is relatively recent, but the greenhouse gas has been playing a critical role in warming our planet for billions of years, according to University of Maryland geologist Jay Kaufman and Virginia Polytechnic Institute geologist Shuhai Xiao.

Their results, which provide the best evidence to date of the age of the Calvin cycle—the photosynthetic cycle by which plants convert light energy and CO2 into cellular tissue—will be publishe

Distant Star Bursts Unlock Secrets of Galaxy Formation

Revealing images produced by one of the world’s most sophisticated telescopes are enabling a team of Edinburgh astronomers to see clearly for the first time how distant galaxies were formed 12 billion years ago. Scientists from the UK Astronomy Technology Centre (UK ATC) and the University of Edinburgh have been targeting the biggest and most distant galaxies in the Universe with the world’s most sensitive submillimetre camera, SCUBA. The camera, built in Edinburgh, is operated on the James Clerk Ma

New Ultrasound Technique Enhances Cerebral Palsy Diagnosis

Children with cerebral palsy are set to benefit from the first study of its kind in the UK.

Cerebral Palsy (CP) is notoriously difficult to manage because of the different degrees of severity and clinical difficulties in assessing the results of treatment. One of the answers could be to use ultrasound scanning to visualize the damage to muscles and assess their condition.

Around 200 children, aged three to six years, will undergo tests to explore how ultrasound can be used t

Attack of the crazy ants – invasional &#146;meltdown&#146; on an oceanic island

Biological invasions have well-known direct effects on native ecosystems but may also unleash forces with complex, unexpected consequences. These ecological surprises may be especially common in simple systems, like islands, following introduction of ’megainvaders,’ like tramp ants.

In the September issue of Ecology Letters, O’Dowd, Green, and Lake show that impacts of invasion by the crazy ant Anoplolepis gracilipes ramify through the food web in rainforest on Christmas Isla

High blood pressure, fatty deposits are &#146;bit players&#146; in bulging arteries

Age, gender, body size are better predictors of aortic aneurysm; genetics are likely important

Contrary to long-accepted conventional wisdom and to current theories, high blood pressure and other risk factors for plaque buildup are not major factors in the dangerous ballooning of blood vessels near the heart, according to a Mayo Clinic study published in the Journal of the American College of Cardiology this week.

New Technique Cuts Radiation Dose Calculation Time

Researchers at Washington University in St. Louis have developed a technique that drastically decreases the time a radiologist spends calculating radiation dosages and also provides a more carefully controlled dosage with less damage to nearby healthy tissues.

UCLA Scientists Develop Method to Flush Hidden HIV from Body

UCLA AIDS Institute scientists have devised a new technique to switch on and drive hibernating HIV from its hiding places in the body. Reported in the September issue of Immunity, the research suggests a possible therapeutic strategy to kill the hidden virus so people who are HIV-positive could eventually stop taking antiretroviral medications.

“Our findings show potential for flushing HIV out of its hiding places in the body,” said Dr. Jerome Zack, principal investigator and associate dire

80% of Hip Replacement Patients Fit for Minimally Invasive Surgery

93 Percent Leave Hospital Same Day; Even Seniors Can Have Outpatient Surgery

After analyzing safety and efficacy data from an initial group of 120 minimally invasive hip surgery patients, Chicago’s Rush-Presbyterian-St. Luke’s Medical Center orthopedic surgeon Dr. Richard A. Berger says that 80 percent of hip replacement patients are eligible for minimally invasive hip surgery procedure over the conventional 10-12 inch single incision surgery.
