One white-faced capuchin monkey sticks its fingers deep into the eye sockets of another capuchin it’s friends with. A capuchin uses her ally’s body parts to whack their common enemy. These behaviors become entrenched in the repertoires of the inventors. But in the first case, the behavior spreads to other group members, and in the second case it does not. (more…)

Wind Farm Design Layout Impacts Species Success
How a wind energy facility is designed can influence the behavior of animal predators and their prey, according to a recent study published in The Journal of Wildlife Management by researchers at the University of California, Davis, and the U.S. Geological Survey. (more…)
MBL scientist studies how aggression fits game theory model of behavior
It sounds like Shakespearean drama: A male fights to protect his mate after a rival steals her away, using all his cunning and strength to win her back. Yet this encounter played out in the sea between three cuttlefish—the first time such behavior has been filmed in the wild. (more…)
Researchers find prenatal infection may create risk for later disorders
The Zika virus now active in numerous countries, and the severe birth defects associated with it, makes it clear that infection in pregnant women can have immediate and devastating effects on the developing baby. (more…)
Think of the Sahara and you will conjure images of a vast desert landscape, with nothing but sand as far as the eye can see. But for a period of about 10,000 years, the Sahara was characterized by lush, green vegetation and a network of lakes, rivers and deltas. (more…)
You wouldn’t hear the mating song of the male fruit fly as you reached for the infested bananas in your kitchen. Yet, the neural activity behind the insect’s amorous call could help scientists understand how you made the quick decision to pull your hand back from the tiny swarm.
Male fruit flies base the pitch and tempo of their mating song on the movement and behavior of their desired female, Princeton University researchers have discovered. In the animal kingdom, lusty warblers such as birds typically have a mating song with a stereotyped pattern. A fruit fly’s song, however, is an unordered series of loud purrs and soft drones made by wing vibrations, the researchers reported in the journal Nature. A male adjusts his song in reaction to his specific environment, which in this case is the distance and speed of a female — the faster and farther away she’s moving, the louder he “sings.” (more…)
ANN ARBOR — What started as a politically liberal Facebook meme in support of health care reform morphed as it spread across the social network into hundreds of thousands of variations—some just a few words from the original, but others centered on taxes, beer, or Star Wars’ villain Jabba the Hutt.
The twists on the original text over time in many ways mirrored the evolution of biological genes, researchers from the University of Michigan and Facebook have found. (more…)
A Yale study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago this month with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. The Yale School of Public Health-led analysis is published in the Journal of the American Medical Association.
The study used mathematical models to calculate the long-term effect of the seminal report, and subsequent anti-smoking measures, over the past half-century. These cumulative efforts have significantly reshaped public attitudes and behaviors concerning cigarettes and other forms of tobacco, note the researchers. (more…)
