Warm nights could flood the atmosphere with carbon under climate change Posted: 07 Dec 2015 01:57 PM PST A new study suggests that hotter nights may wield more influence than previously thought over the planet's atmosphere as global temperatures rise -- and could eventually lead to more carbon flooding the atmosphere.

Seeing viruses in a new light Posted: 07 Dec 2015 01:57 PM PST If researchers can understand how viruses assemble, they may be able to design drugs that prevent viruses from forming in the first place. Unfortunately, how exactly viruses self-assemble has long remained a mystery because it happens very quickly and at such small length-scales. Now, there is a system to track nanometer-sized viruses at sub-millisecond time scales. The method is the first step towards tracking individual proteins and genomic molecules at high speeds as they assemble to create a virus.

Could hippos be meat eaters? Posted: 07 Dec 2015 01:43 PM PST People often think hippos are herbivores with big smiling faces. Every now and then, reports of a hippo of hunting down prey, eating a carcass, or stealing prey from a crocodile are heard, but they're typically considered 'aberrant' or 'unusual' behavior. Now, however, researchers demonstrate that carnivory, or eating meat, is not uncommon among hippos at all, and that this behavior may increase their susceptibility to mass mortality during anthrax outbreaks.

Contaminants in New York City’s community gardens Posted: 07 Dec 2015 01:43 PM PST While community gardens provide benefits including urban green space, opportunities for recreation, art expression, social gathering, and improved diets, urban gardening may also increase the opportunity for exposure to common urban soil contaminants such as polycyclic aromatic hydrocarbons (PAHs).

Cities support a greater number of threatened species than non-urban areas Posted: 07 Dec 2015 01:43 PM PST The earth is facing a catastrophic species extinction crisis. The dominant approach to conservation has been to focus on protecting pristine environments, but new research from Australia demonstrates that on average, urban environments contain disproportionately more threatened protected species in a given area than non-urban environments. Investigators looked at the distributions of 1,643 protected species in Australia, and counted up the number of these species that occurred in square-kilometer units across the continent.
