Overfishing Threatens the Survival of Seabirds
From gannets to seagulls, puffins to penguins, all seabirds suffer the same drop in birth rates when the supply of fish drops to less than a third of maximum capacity. That's the result from an international study on the relationships between predators and prey in seven ecosystems around the world, published in the magazine Science and coordinated by Philippe Cury, an IRD researcher. Based on nearly 450 cumulative years of observation, the research team compared the growth in fish supplies and the reproductive patterns of 14 species of coastal birds. These birds mainly feed on sardines, anchovies, herring and prawns, all of which are victims of over fishing. Below the critical level of one third of the fish biomass, the birds -- and the stability of the entire ecosystem -- come under threat.

Winning Makes People More Aggressive Toward the Defeated
In this world, there are winners and losers -- and, for your own safety, it is best to fear the winners. A new study found that winners -- those who outperformed others on a competitive task -- acted more aggressively against the people they beat than the losers did against the victors.

Nanofiber Breakthrough Holds Promise for Medicine and Microprocessors
A new method for creating nanofibers made of proteins, developed by researchers at Polytechnic Institute of New York University (NYU-Poly), promises to greatly improve drug delivery methods for the treatment of cancers, heart disorders and Alzheimer's disease, as well as aid in the regeneration of human tissue, bone and cartilage.

Genetics of Endangered African Monkey Suggest Troubles from Warming Climate
A rare and endangered monkey in an African equatorial rainforest is providing a look into our climatic future through its DNA. Its genes show that wild drills (Mandrillus leucophaeus), already an overhunted species, may see a dramatic population decline if the forest dries out and vegetation becomes sparser amid warming temperatures, researchers report.

Two New Extinct Camel Species Discovered at Panama Canal Excavation
The discovery of two new extinct camel species by University of Florida scientists sheds new light on the history of the tropics, a region containing more than half the world's biodiversity and some of its most important ecosystems.

How Insects 'Remodel' Their Bodies Between Life Stages
It's one of life's special moments: a child finds a fat caterpillar, puts it in a jar with a twig and a few leaves, and awakens one day to find the caterpillar has disappeared and an elegant but apparently lifeless case now hangs from the twig.

Earthworms to Blame for Decline of Ovenbirds in Northern Midwest Forests
A recent decline in ovenbirds (Seiurus aurocapilla), a ground-nesting migratory songbird, in forests in the northern Midwest United States is being linked by scientists to a seemingly unlikely culprit: earthworms.

Bacteria Tend Leafcutter Ants' Gardens
Leafcutter ants, the tiny red dots known for carrying green leaves as they march through tropical forests, are also talented farmers that cultivate gardens of fungi and bacteria. Ants eat fungi from the so-called fungal gardens, but the bacteria's role has been unclear until now.
