Study suggests evolutionary link between diet, brain size in orangutans

... habitats on Sumatra. "The eastern parts of Borneo suffer more from El Niño-related droughts than parts of western Borneo," the scientists wrote. "The effects of El Niño on tropical rain forest composition and diversity are also more marked in eastern compared to western parts." So Taylor and van Schaik u...

A human taste for rarity spells disaster for endangered species

...which individuals of many plant and animal species suffer reduced fitness at low population densities, which increases their extinction risk. The authors' model now shows that humans can trigger an "anthropogenic Allee effect" in rare species through a paradox of value. When rarity acquires value, prices fo...

Stormy days ahead for coral reefs

...del to predict how much damage a reef is likely to suffer when confronted with might of an angry sea. In a paper in the international scientific journal Nature, Dr Joshua Madin and Dr Sean Connolly use mathematical models to calculate the forces that coral is subjected to by wave, storm surge or tsunam...

Finding the right mix: A biomaterial blend library

...an body? Will a patient accept the new material or suffer an inflammatory response? And can that material survive in a human's complex system? To tackle such questions, researchers at the National Institute of Standards and Technology (NIST) and the New Jersey Center for Biomaterials (NJCB) at Rutgers Uni...

Master planners in brain may coordinate other areas' roles in cognitive tasks

...ic mutism, a condition that occurs in patients who suffer a lesion from stroke or surgery that includes the cingulate. To varying degrees, such patients are minimally active. "If you give them a cup of coffee, they'll drink it, but they'd never ask for a cup of coffee," Petersen explains. "If you ask them ...

ABCB6 is key to production of heme in hemoglobin

...mental disorders. "Also, people with porphyria can suffer sudden, acute attacks if they take certain tranquilizers and other drugs that interfere with this system," Schuetz said. "So our work contributes to the overall picture of how disruption of the biochemical pathway of heme production can cause a varie...

Clot-busting drug helps revive cardiac arrest patients

...s. The heart stops beating and the brain starts to suffer permanent damage within four to six minutes. Death quickly follows. The standard treatment for cardiac arrest is Advanced Cardiac Life Support (ACLS) measures, which include cardiopulmonary resuscitation (CPR), drugs such as adrenaline, and defibri...

A surprise about our body clock

...niversity of Toronto. "Each year, 70,000 Canadians suffer from a heart attack and many of them are left with crushing disabilities, mainly because the heart muscle is not able to regenerate after a heart attack. This study identifies the method the body employs to repair the heart and provides new therapies...

Gene linked to rare disease activates fat breakdown

...ome (CDS), who carry a mutant version of the gene, suffer from the widespread buildup of fat in tissues throughout their bodies. The group found that the gene "CGI-58" is a strong activator of one of three lipid-degrading enzymes, or lipases, that disassemble triacylglycerol. Triacylglycerol is perhaps mor...

Large-scale genomics project will hunt genes behind common childhood diseases

To accomplish the large-scale genotyping analysis, the Center for Applied Genomics at Children's Hospital will use the BeadLab, a highly automated laboratory that will be able to process 264 patient samples...

UBC researchers find stroke death channel

...d cell death. Every year, 50,000 Canadians suffer a stroke. Another 300,000 people are living with the consequences of stroke, which is the leading cause of adult disability in Canada. The next step in the investigation will be to determine the cause of the hemichannel malfunction. Scientists can ...

Research offers new hope for preterm babies
