Activation of brain region can change a monkey's choice
Artificially stimulating a brain region believed to play a key role in learning, reward and motivation induced monkeys to change which of two images they choose to look at. In experiments reported online ...
Computers see through faked expressions of pain better than people
A joint study by researchers at the University of California San Diego and the University of Toronto has found that a computer system spots real or faked expressions of pain more accurately than people can.
Antarctic moss lives after 1,500 years under ice
Researchers from the British Antarctic Survey and University of Reading report in Current Biology on March 17 that Antarctic mosses can essentially come back to life after 1,500 completely inactive years ...

A whale with a distinctly human-like voice
For the first time, researchers have been able to show by acoustic analysis that whales—or at least one very special white whale—can imitate the voices of humans. That's a surprise, because whales typically ...
Cuttlefish have high definition polarization vision, researchers discover
Cuttlefish have the most acute polarization vision yet found in any animal, researchers at the University of Bristol have discovered by showing them movies on a modified LCD computer screen to test their eyesight.
Genetic analysis shows tortoise species thought to be extinct for 150 years still lives
Dozens of giant tortoises of a species believed extinct for 150 years may still be living at a remote location in the Galapagos Islands, a genetic analysis conducted by Yale University researchers reveals.
Genomic data support early contact between Easter Island and Americas
People may have been making their way from Easter Island to the Americas well before the Dutch commander Jakob Roggeveen arrived with his ships in 1722, according to new genomic evidence showing that the ...
Researchers record sight neurons in jumping spider brain
For the first time, a team of interdisciplinary researchers have made recordings of neurons associated with visual perception inside the poppy seed-sized brain of a jumping spider (Phidippus audax).
Cell architecture: Finding common ground
When it comes to cellular architecture, function follows form. Plant cells contain a dynamic cytoskeleton which is responsible for directing cell growth, development, movement, and division. So over time, changes in the cytoskeleton ...
Are male brains wired to ignore food for sex?
Choosing between two good things can be tough. When animals must decide between feeding and mating, it can get even trickier. In a discovery that might ring true even for some humans, researchers have shown that male brains ...
Amphibian communities collapse in wake of viral outbreak
Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian—the common midwife toad, the common toad, ...
