Researchers say they now know that offspring are inheriting dysfunction in their mitochondria as a result of their parents' substance abuse. This dysfunction causes these individuals to show early signs of age-related disease when they're still considered young, usually in their 40s.

There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.

Researchers have developed an inexpensive bandage that uses an electric field to promote healing in chronic wounds. In animal testing, wounds that were treated with these electric bandages healed 30% faster than wounds treated with conventional bandages.

In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.

Cocaine binds to a specific transporter in the brain that is responsible for regulating dopamine levels. Researchers have studied and described the process, producing new knowledge that may bring us a step closer to designing a drug for cocaine abuse.

New research has found a surprising link between grooming and physiological stress in wild baboons. While grooming often calms, this study suggests it can sometimes elevate stress levels. This gives us an intriguing look into primate behavior and social dynamics.

Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.

Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.

Whether dangerous staphylococci survive in the nose depends on what other bacteria are present -- and how they obtain iron.

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
