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.

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.
Researchers uncover secrets of internal cell fine-tuning
New research from scientists at the University of Kent has shown for the first time how the structures inside cells are regulated – a breakthrough that could have a major impact on cancer therapy development.
Largest-ever study of spider genetics shows orb weaver spiders do not share common origins
For decades, the story of spider evolution went like this: As insects became more and more diverse, with some species taking to the skies, spiders evolved new hunting strategies, including the ability to ...
Clone collection: First comprehensive library of master genetic switches in plants
Researchers have created the first comprehensive library of genetic switches in plants, setting the stage for scientists around the globe to better understand how plants adapt to environmental changes and to design more robust ...
Chimpanzee intelligence determined by genes
A chimpanzee's intelligence is largely determined by its genes, while environmental factors may be less important than scientists previously thought, according to a Georgia State University research study.
Why 'whispers' among bees sometimes evolve into 'shouts'
Let's say you're a bee and you've spotted a new and particularly lucrative source of nectar and pollen. What's the best way to communicate the location of this prize cache of food to the rest of your nestmates ...
