The roots of human altruism

August 27, 2014 10:38 am | by EurekAlert! | News | Comments

Scientists have long been searching for the factor that determines why humans often behave so selflessly. It was known that humans share this tendency with species of small Latin American primates of the family Callitrichidae (tamarins and marmosets), leading some to suggest that cooperative care for the young, which is ubiquitous in this family, was responsible for spontaneous helping behavior....

DTU researchers film protein quake for the first time

August 27, 2014 10:21 am | by EurekAlert! | News | Comments

One of nature's mysteries is how plants survive impact by the huge amounts of energy contained in the sun's rays, while using this energy for photosynthesis. The hypothesis is that the light-absorbing proteins in the plant's blades quickly dissipate the energy throughout the entire protein molecule through so-called protein quakes....

Museum specimens, modern cities show how an insect pest will respond to climate change

August 27, 2014 9:49 am | by EurekAlert! | News | Comments

Researchers from North Carolina State University have found that century-old museum specimens hold clues to how global climate change will affect a common insect pest that can weaken and kill trees – and the news is not good. "Recent studies found that scale insect populations increase on oak and maple trees in warmer urban areas, which raises the possibility that these pests may also increase with global warming,"....
