Immersed in violence: How 3-D gaming affects video game players

Posted: 21 Oct 2014 11:53 AM PDT

Playing violent video games in 3-D makes everything seem more real – and that may have troubling consequences for players, a new study reveals. Researchers found that people who played violent video games in 3-D showed more evidence of anger afterward than did people who played using traditional 2-D systems -- even those with large screens.

Biologists found the could quite accurately predict what type of predator was threatening a squirrel by analyzing its sounds and tail movements.

Kung fu stegosaur: Lethal fighters when necessary

Posted: 21 Oct 2014 08:49 AM PDT

Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound -- in the conical shape of a stegosaur tail spike -- would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life.

Tarantula venom illuminates electrical activity in live cells

Posted: 21 Oct 2014 07:11 AM PDT

A cellular probe that combines a tarantula toxin with a fluorescent compound has been developed to help scientists observe electrical activity in neurons and other cells. This is the first time researchers have been able to visually observe these electrical signaling proteins turn on without genetic modification.

Quantum holograms as atomic scale memory keepsake

A rich vocabulary can protect against cognitive impairment

Posted: 21 Oct 2014 05:55 AM PDT

Some people suffer incipient dementia as they get older. To make up for this loss, the brain's cognitive reserve is put to the test. Researchers have studied what factors can help to improve this ability and they conclude that having a higher level of vocabulary is one such factor. 'Cognitive reserve' is the name given to the brain's capacity to compensate for the loss of its functions. This reserve cannot be measured directly; rather, it is calculated through indicators believed to increase this capacity.
