Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals
Some species have the equivalent of many more than two sexes, but most do not. A new model suggests the reason depends on how often they mate
A new theory may change the debate over evolution and self-interest among ants, bees and other social bugs
The findings add to the longstanding debate over which were the first self-replicating molecules
When it comes to abilities like outwitting foes, younger people are simply better at responding in novel situations
Feelings of affiliation reduce disgust
A new study shows the brain repurposes everyday neural networks to learn high-level scientific concepts
In a chaotic environment people who do not feel in control tend to overeat
A new type of lens adjusts its prescription according to where the user looks
Before learning language, infants distinguish between categories such as green and blue
A new study finds that a key protein implicated in Alzheimer’s may normally protect the brain from infection
Brain structure in emotion-regulation areas—and possibly the risk of mood disorders—is inherited down the female line
Data from failed experiments combines with machine learning to predict successful chemical reactions and form new hypotheses
A study in rats finds that increased sensitivity to ghrelin causes weight gain and increased body fat, but does not augment appetite
Processing high-level math concepts uses the same neural networks as the basic math skills a child is born with
The finding gives researchers insight into dopamine beta-hydroxylase, an enzyme that balances the activity of two key brain-signaling molecules
The Japanese great tit combines two calls in a specific order and does not respond to a recording of the calls combined in reverse order, apparently demonstrating compositional syntax.
A study in mice shows that the normal process by which the brain prunes excess synapses during development may be hijacked early on in the progression of Alzheimer’s and other neurodegenerative diseases...
A new study in mice demonstrates that manipulating the microbiome can influence the extent of brain damage caused by a stroke
A new study in rats could one day benefit people suffering neurological conditions associated with the buildup of unwanted proteins in the brain, including traumatic brain injury and Alzheimer’s...
