Bolivian rainforest study suggests feeding behavior in monkeys and humans have ancient, shared roots

Behavioural ecologists working in Bolivia have found that wild spider monkeys control their diets in a similar way to humans, contrary to what has been thought up to now. Rather than trying to maximize their daily energy intake, the monkeys tightly regulate their daily protein intake, so that it s...

Babies born to native high-altitude mothers have decreased risk of low birth weight

BETHESDA, Md. (May 18, 2009) Pregnant women who are indigenous to the Andes Mountains deliver more blood and oxygen to their fetuses at high altitude than do women of European descent. The study helps explain why babies of Andean descent born at high altitude weigh more than European babies born a...

Signals from stroking have direct route to brain

Nerve signals that tell the brain that we are being slowly stroked on the skin have their own specialised nerve fibres in the skin. This is shown by a new study from the Sahlgrenska Academy, University of Gothenburg, Sweden. The discovery may explain why touching the skin can relieve pain. The s...

Scientists find climate change to have paradoxical effects in coastal wetlands

Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However, a team of scientists, including two Smithsonian ecologists, have found that this same increase in CO 2 may ironically counterbalance some of its negative effects on one of the p...

MIT: Why we have difficulty recognizing faces in photo negatives

CAMBRIDGE, Mass.--Humans excel at recognizing faces, but how we do this has been an abiding mystery in neuroscience and psychology. In an effort to explain our success in this area, researchers are taking a closer look at how and why we fail. A new study from MIT looks at a particularly striki...

Children who are dissatisfied with their appearance often have problems with their peer group

Being satisfied with one's appearance is one of the most important prerequisites for a positive self image. However, in today's appearance culture it is the rule rather than the exception that children and young people are dissatisfied with their appearance. Those children who are teased or subj...

Rising sea levels set to have major impacts around the world

Research presented today at the International Scientific Congress on Climate Change in Copenhagen shows that the upper range of sea level rise by 2100 could be in the range of about one meter, or possibly more. In the lower end of the spectrum it looks increasingly unlikely that sea level rise wil...

Researchers may have found why women have an edge on salt-sensitive hypertension

AUGUSTA, Ga. Researchers may have found why women have an edge in keeping a healthier balance between the amount of salt they eat and excrete - at least before reaching menopause. Premenopausal women are known to have fewer problems with salt-sensitive hypertension and hypertension in general,...

Tree deaths have doubled across the western US

Tree death rates have more than doubled over the last few decades in old-growth forests of the western United States, and the most probable cause of the worrisome trend is regional warming, according to a U.S. Geological Survey-led (USGS) study published in Science on January 23. The study fo...

Invasions by alien plants have been mapped in European Union

Four, three, two, one . . . pterosaurs have lift off

Pterosaurs have long suffered an identity crisis. Pop culture heedlessly and wrongly lumps these extinct flying lizards in with dinosaurs. Even paleontologists assumed that because the creatures flew, they were birdlike in many ways, such as using only two legs to take flight. Now comes w...

Stronger coastal winds due to climate change may have far-reaching effects

SAN FRANCISCO, CA--Future increases in wind strength along the California coast may have far-reaching effects, including more intense upwelling of cold water along the coast early in the season and increased fire danger in Southern California, according to researchers at the Climate Change and Imp...

Male dinosaurs may have been prehistoric babysitters, study shows
