Infants and young children have brains with a superpower, of sorts, say neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain's two hemispheres, youngsters use both the right and left hemispheres to do the same task. The finding suggests a possible reason why children appear to recover from neural injury much easier than adults.

Discovery of early bony fish casts doubt on accepted ideas about evolutionary history of vertebratesThe partial skull of an armoured fish that swam in the oceans over 400m years ago could turn the evolutionary history of sharks on its head, researchers have said.Bony fish, such as salmon and tuna, as well as almost all terrestrial vertebrates, from birds to humans, have skeletons that end up made...
The answer to today’s puzzleEarlier today I asked you to construct a triangle whose existence seems to defy reason.Show that there is a triangle, the sum of whose three heights is less than 1mm, that has an area greater than the surface of the Earth (510m km2). Continue...
Plant protein foods -- like lentils, beans, and nuts --c an provide vital nutrients using a small fraction of the land required to produce meat and dairy. By shifting to these foods, much of the remaining land could support ecosystems that absorb CO2, according to a new study.
When acorn woodpeckers inhabiting high-quality territories die, nearby birds begin a battle royal to win the vacant spot. Researchers used radio tags to understand the immense effort woodpecker warriors expend traveling to and fighting in these dangerous battles. They also found spectator woodpeckers go to great lengths to collect social information, coming from kilometers around just to watch...
Recent cancer studies have shown that genomic mutations leading to cancer can occur years, or even decades, before a patient is diagnosed. Researchers have developed a statistical model that analyses genomic data to predict whether a patient has a high or low risk of developing esophageal cancer. The results could enable early detection and improve treatment of oesophageal cancer in future.
Scientists looked at links between the personality profiles of over 3.3m US residents and the 'topography' of 37,227 ZIP codes. Distinct psychological mix associated with mountain populations is consistent with theory that harsh frontiers attracted certain personalities. Researchers argue this may be residual from US frontier expansion during the 19th century, as personality pattern is strongest...
In a significant advance, researchers working towards a brain-controlled prosthetic limb at the UC San Francisco Weill Institute for Neurosciences have shown that machine learning techniques helped a paralyzed individual learn to control a computer cursor using their brain activity without requiring extensive daily retraining, which has been a requirement of all past brain-computer interface (BCI)...

Ocean warming is paradoxically driving bottom-dwelling invertebrates -- including sea scallops, blue mussels, surfclams and quahogs that are valuable to the shellfish industry -- into warmer waters and threatening their survival, a new study shows.
In rodents with type 2 diabetes, a single surgical injection of a protein called fibroblast growth factor 1 can restore blood sugar levels to normal for weeks or months. Yet how this growth factor acts in the brain to generate this lasting benefit has been poorly understood. Clarifying how this occurs might lead to more effective diabetes treatments that tap into the brain's inherent potential to...
