Scientists at Scripps Research have successfully tested a potential new smoking-cessation treatment in rodents.
In a study published online in Science Advances on Oct. 17, 2018, the scientists gave nicotine-dependent rats an engineered enzyme that breaks down nicotine in the bloodstream before it can reach the brain. Treatment quickly reduced the animals' motivation to take nicotine,...
Youngsters learn many important behaviors by imitating adults. But young learners are selective in who they copy, and scientists don't understand how they choose the right teacher.
Young male zebra finches must learn to copy the song of an adult tutor in order to ultimately attract a mate. Researchers already knew that juveniles don't copy songs...
Like people, blue crabs aren't all the same sizes and shapes. Now Rutgers scientists have discovered substantial differences in the body structures of larval crab siblings and among larvae from different mothers. And that can mean the difference between an early death and survival into adulthood for this important commercial and recreational species.
Unlike other crab...
As winter in New England seems to get warmer, fall lingers longer and spring comes into bloom earlier, areas like northern New Hampshire and western Maine are seeing an unusual continued increase in winter ticks which are endangering the moose population. Researchers at the University of New Hampshire have found that the swell of infestations...
Could bats' cave-dwelling nocturnal habits over eons enhanced their echolocation acoustic abilities, but also spurred their loss of vision?
A new study led by Bruno Simões, Emma Teeling and colleagues has examined this question in the evolution of color vision genes across a large and diverse group of bat species.
They show that the popular expression of...
Since the reintroduction of wolves to Yellowstone National Park in 1995, the park's ecosystem has become a deeply complex and heterogeneous system, aided by a strategy of minimal human intervention. The new study is a synthesis of 40 years of research on large mammals in Yellowstone National Park, conducted by University of Alberta ecologist Mark...
