Chimpanzees are renowned for their complex tool using behaviors and wide array of tool assemblages. However, the tool using repertoire of these apes in central Africa’s Congo Basin has remained an enigma, based mainly on indirect evidence and fleeting observations.
In this study, a new type of remote video technology was used to study chimpanzee behavior at termite nests in the Goualougo Triangle, Republic of Congo. From six-months of remote video surveillance at termite nests,
Brett Wong is on a mission to help uncover the mechanism that regulates our ability to withstand heat stress. The goal is to help improve survival rates among those who suffer the most during heat waves: the elderly and people with conditions such as diabetes and heart disease.
The award-winning University of Oregon doctoral degree student’s research is the first to identify histamine receptors as contributing to increased blood flow during heat stress. Skin blood flow is a
New protein structure is a first step toward preventing E. coli diseases
Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory and Stony Brook University have determined the two-dimensional crystal structure of a membrane protein involved in the process by which the Escherichia coli (E. coli) bacteria infects a human. This protein structure is a first step to better understanding how an E. coli infection begins, which may lead to information on how to blo
A Johns Hopkins University graduate student may have solved a problem that has been baffling marine biologists and paleontologists for years: Why do coral reefs disappear from the fossil record during the beginning of the Cretaceous period — 120 million years ago — only to reappear after its end 35 million years ago?
The possible answer: Ancient seawater’s low magnesium-to-calcium ratio during this interval made it difficult for the marine animals — which build their sk
In the treatment of coronary artery disease, a sirolimus drug-coated stent causes less inflammation than bare metal stents, according to preliminary research presented at the American Heart Association annual meeting by Loyola University Health System, Maywood, Ill.
“Inflammatory response is a sign of advancing heart disease, so the less inflammation the better,” said lead author Dr. Fred Leya, professor of medicine/cardiology, Loyola University Chicago Stritch School of Medicine.
New ARIC data confirm enzyme’s potential as a target for independent cardiovascular diagnosis and therapy
High levels of an enzyme – lipoprotein-associated phospholipase A2 (Lp-PLA2) – believed to trigger a cascade of inflammatory events in atherosclerosis can independently predict increased risk of stroke, even after accounting for both traditional and novel cardiovascular risk factors, according to a new analysis by investigators from the ongoing Atherosclerosis Risk in
A new study by a New York University professor suggests perceptual maturity in infants develops in the early months after birth as a result of piecing together fragments of the visual scene. The findings, published in the latest issue of Psychological Science, shed new light on our fundamental knowledge of how objects behave, giving weight to the scientific camp that argues such development is a “constructed” rather than an “innate” phenomenon.
Advocates of innate perception h
U of MN study finds dinner table atmosphere is also important
It’s not only the routine of sitting down to dinner as a family, but the importance, structure, and atmosphere of family meals that may help steer adolescent girls from eating disorders. University of Minnesota researchers found that girls who ate regular family meals in a structured and positive environment were less likely to exhibit extreme weight control behaviors such as diet pill use, vomiting, and chronic d
University of Pittsburgh Researchers note particular risk for women with both metabolic cardiovascular and polycystic ovary syndromes
Polycystic ovary syndrome (PCOS), a disorder characterized by metabolic and endocrine abnormalities, affects millions of women in the United States alone and endangers their hearts by causing early buildup of calcium in coronary arteries, researchers at the University of Pittsburgh’s Graduate School of Public Health report in the November is
The World Chiropractic Alliance (WCA) is recommending that people of all ages add chiropractic to their strategy for warding off and fighting the flu and its effects this season.
Spinal adjustments can have a positive effect on immune function, the WCA asserts, citing a growing number of researchers who are exploring the common denominators in disease processes, and the role of the nervous, immune, and hormonal systems in development of immune related illnesses,

New research presented today at the American Heart Association’s Scientific Sessions reveals that plant sterols from soy added to a cocoa-based snack bar can significantly reduce cholesterol levels. This study demonstrates how certain plant nutrients can promote heart health when included in snack foods. Based on this research and decades of research on cocoa, Mars Incorporated has developed a new cocoa-based, sterol-containing snack bar, CocoaVia(tm).

Scientists for the first time have identified a fault in the brain waves of schizophrenics that may explain their hallucinations and disturbed thinking. The study, by a team at the Veterans Affairs (VA) Boston Healthcare System and Harvard Medical School, appears in the Nov. 8 Proceedings of the National Academy of Sciences.
The researchers studied the brain waves of normal and schizophrenic patients as they responded to images. Those with the disorder showed no electrical activ
The pulmonary artery catheter (PAC), a device that measures pressures and flows in the heart, is frequently used to diagnose, monitor, and guide treatment of congestive heart failure and other conditions. However, use of the PAC has been controversial with varying opinions as to its risk and benefits. New findings from a multi-center study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health show that the PAC did not significantly increase or
Delays in emergency angioplasty linked to higher death risk
In a heart attack, the saying goes, “Time is muscle.” The faster a person gets treated, the better his or her chances of survival and recovery. But a new study finds that women who have heart attacks wait longer than men to receive an emergency procedure that can re-open clogged blood vessels and restore blood flow to the heart muscle. The study also finds that the longer any patient waits for this treatment, the higher h
Around 80 per cent of modern thoroughbred racehorses have in their pedigree the 18th century horse Eclipse, which went its entire racing career unbeaten. 200 years later the question of what makes a fast racehorse still perplexes trainers and racing fans but researchers at The Royal Veterinary College may have found the answer to this and other questions on animal locomotion.
The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), has combined d
This synthetic aperture radar image of the surface of Saturn’s moon Titan was taken on 26 October 2004, when the NASA/ESA/ASI Cassini-Huygens spacecraft flew about 2500 kilometres above the surface and acquired radar data for the first time.
The radar illumination was from the south: dark regions may represent areas that are smooth, made of radar-absorbing materials, or are sloped away from the direction of illumination.
A striking bright feature stretches from up
