A new drug to manage resistant chronic pain

Neuropathic pain is the culprit behind many cases of chronic pain, resistant to common drugs. A new drug inhibits the transmission of pain signals throughout the body, protecting against not only neuropathic pain but also epileptic seizures, new study suggests.

Neurodevelopmental disorders: How human cells ‘hold hands’

Biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex — the outermost layer of the brain where language, thought and other higher functions take place — disrupts the formation of neural circuitry.

Mutltitasking hurts performance but makes you feel better

People aren’t very good at media multitasking – like reading a book while watching TV – but do it anyway because it makes them feel good, a new study suggests. The findings provide clues as to why multitasking is so popular, even though many studies show it is not productive.

Video games can teach how to shoot guns more accurately and aim for the head

Just 20 minutes of playing a violent shooting video game made players more accurate when firing a realistic gun at a mannequin — and more likely to aim for and hit the head, a new study found.

Global warming refuge discovered near at-risk Pacific island nation of Kiribati

Scientists predict ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a way that mitigates warming near a handful of islands right on the equator.

Halting an enzyme can slow multiple sclerosis in mice

An antibody that neutralizes Kallikrein 6 is capable of staving off MS in mice, new research suggests.

Cost study shows timing crucial in appendectomies

Removing a child’s ruptured appendix sooner rather than later significantly lowers hospital costs and charges, according to a recently published study.

Enzyme could slow part of the aging process in astronauts — and the elderly

New research suggests that an enzyme, called 5-lipoxygenase, plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight. Additionally, since space conditions initiate health problems that mimic aging on Earth, this discovery may lead to therapeutics that extend lives by bolstering the immune systems of the elderly.

Vitamin D may protect against viral infections during the winter

Vitamin D may be known as the sunshine vitamin, but a new research report shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.

Light weights are just as good for building muscle, getting stronger, researchers find

Lifting less weight more times is just as effective at building muscle as training with heavy weights, a finding that turns conventional wisdom on its head. The key to muscle gain, say the researchers, is working to the point of fatigue.
