Is artificial intelligence faster than brain learning? Study finds

Can the brain, with its limited realization of precise mathematical operations, compete with advanced artificial intelligence systems implemented on fast and parallel computers? From our daily experience we know that for many tasks the answer is yes!

The results potentially provide a new conceptual framework for understanding brain inflammation and its relationship to brain cell loss and neurological deficits after head injury (Shutterstock)

Extinction of elephants could affect atmospheric carbon levels: Study

If the already critically endangered elephants go extinct, the rainforests of Central and West Africa, the world's second largest, will lose between six and nine percent of their ability to capture atmospheric carbon.

Elephants and other megaherbivores affect the abundance of these trees by feeding more heavily on the low carbon density trees. (Shutterstock)

Researchers suggest how brain games predict risk of viral infection

Subtle variations in every day cognitive performance can signal changes in brain states that are known to increase the risk of illness such as stress, fatigue and poor sleep. The team wanted to measure cognitive function and explore whether it was predictive of immune performance after exposure to a respiratory virus.

Cognitive variability, measured with an at-home, digital self-test, turned out to be very predictive.(Reuters)

Study finds important clues to dispersal of giant rhinos across Asia

According to a study published in the journal "Communications Biology," the giant rhino, Paraceratherium, was dispersed across South and Central Asia via the Tibetan Plateau.

Up to the Late Oligocene, the evolution and migration from P. bugtiense to P. linxiaense and P. lepidum show that the "Tibetan Plateau" was not yet a barrier to the movement of the largest land mammal.
