Kodiak brown bears are abandoning salmon-their iconic prey-due to climate change, according to a new study.
NASA's Aqua satellite passed over Typhoon Hato just hours after it made landfall in southeastern China.
Satellite imagery revealed that wind shear and cooler sea surface temperatures have taken their toll on the once hurricane Kenneth. Kenneth has now weakened to a tropical storm and continues to be torn apart as seen in imagery from NOAA's GOES-West satellite.
An estimated 17.6 million Americans live within one mile of an active oil or gas well, according to a study published today in Environmental Health Perspectives, a peer-reviewed journal published by the National Institute of Environmental Health Sciences. The study, by researchers at PSE Healthy Energy, a nonprofit research institute, is the first peer-reviewed nationwide measurement of the number of people living in close proximity to actively producing oil and gas wells.
A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.
By performing detailed dissections and corresponding examinations of embryological development, researchers at Midwestern University, led by Margaret Hall, Ph.D. and Jeffrey Plochocki, Ph.D., show that the muscles that control the unique mammalian perineal structures follow a surprisingly ancient pattern.
Though modern horses now have a single toe, their earliest ancestors had three on their front legs, and four on the back. Harvard scientists are shedding new light on what drove those changes, and in a new study show that the dual pressures of increasing body weight and shrinking side toes prompted early horses' middle toes to become dramatically stronger and better able to resist forces.
Mitochondria, the tiny structures inside our cells that generate energy, may play a key role in autism spectrum disorders (ASD). A provocative new study by Children's Hospital of Philadelphia (CHOP)'s pioneering mitochondrial medicine team suggests that variations in mitochondrial DNA (mtDNA) originating during ancient human migrations may be an important contributor to ASD predisposition.
ISCA Technologies, a California-based biotech firm, is working on several innovations to stop outbreaks of malaria-spreading mosquitos before they occur by using pheromones and other naturally occurring attractants.
The vulnerability and conservation value of sub-tropical reefs south of the Great Barrier Reef -- regarded as climate change refuges -- has been highlighted in a new study. University of Queensland School of Biological Sciences researcher Dr Brigitte Sommer said the study of Eastern Australian reefs revealed coral species would likely shift their distribution southward in response to climate change.
