• 22:38 Key to immune cell's 'internal guidance' system discovered

  Read the story at ScienceDaily
  Researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, viruses and bacteria, and lead to more efficient vaccines.

• 22:37 Genetic variant increases risk of common type stroke

  Read the story at ScienceDaily
  A genetic variant that increases the risk of a common type of stroke has been identified by scientists. This is one of the few genetic variants to date to be associated with risk of stroke and the discovery opens up new possibilities for treatment.

• 00:26 Hearing metaphors activates brain regions involved in sensory experience

  Read the story at ScienceDaily
  New brain imaging research reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard.

• 00:26 Whole exome sequencing identifies cause of metabolic disease

  Read the story at ScienceDaily
  Sequencing a patient's entire genome to discover the source of his or her disease is not routine, but geneticists are getting close. A case report shows how researchers can combine a simple blood test with an "executive summary" scan of the genome to diagnose a severe glycosylation disorder.

• 00:09 A lonely heart can make you sick: Middle aged divorced women vulnerable to contracting HIV

  Read the story at ScienceDaily
  Newly divorced middle aged women are more vulnerable to contract HIV and other sexually transmitted diseases, according to new research, because they tend to let their guard down with new sexual partners and avoid using protection since they are not afraid of getting pregnant.

• 00:09 Discovery of extremely long-lived proteins may provide insight into cell aging and neurodegenerative diseases

  Read the story at ScienceDaily
  One of the big mysteries in biology is why cells age. Now scientists report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.

• 20:15 Placebo effect: New study shows how to boost the power of pain relief, without drugs

  Read the story at ScienceDaily
  Placebos reduce pain by creating an expectation of relief. Distraction -- say, doing a puzzle -- relieves it by keeping the brain busy. But do they use the same brain processes? Neuromaging suggests they do. When applying a placebo, scientists see activity in the dorsolateral prefrontal cortex. That's the part of the brain that controls high-level cognitive functions like working memory and attention -- which is what you use to do that distracting puzzle.

• 20:15 Regular use of vitamin and mineral supplements could reduce the risk of colon cancer, study suggests

  Read the story at ScienceDaily
  Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.

• 20:15 Schooling protects refugee children from disease

  Read the story at ScienceDaily
  Refugee children have scant access to medical care and are particularly vulnerable to disease. Fresh research results show that just a few hours of schooling a week may have a pronounced positive impact on their health not only in childhood but later in life when they achieve adulthood.

• 20:15 The complex relationship between memory and silence

  Read the story at ScienceDaily
  People who suffer a traumatic experience often don't talk about it, and many forget it over time. But not talking about something doesn't always mean you'll forget it; if you try to force yourself not to think about white bears, soon you'll be imagining polar bears doing the polka. A group of psychological scientists explore the relationship between silence and memories.

• 20:14 Rare mutations may help explain aneurysm in high-risk families

  Read the story at ScienceDaily
  An innovative approach to genome screening has provided clues about rare mutations that may make people susceptible to brain aneurysms, predisposing them to brain bleeds, according to preliminary research.

• 20:11 Coughing and other respiratory symptoms improve within weeks of smoking cessation

  Read the story at ScienceDaily
  If the proven long-term benefits of smoking cessation are not enough to motivate young adults to stop smoking, a new study shows that 18- to 24-year olds who stop smoking for at least two weeks report substantially fewer respiratory symptoms, especially coughing.

• 17:33 Clopidogrel with aspirin doesn't prevent more small strokes, may increase risk of bleeding and death, researchers report

  Read the story at ScienceDaily
  The anti-blood clot regimen that adds the drug clopidogrel (Plavix) to aspirin treatment is unlikely to prevent recurrent strokes and may increase the risk of bleeding and death in patients with subcortical stroke, according to new research.

  Read the story at ScienceDaily
  Around 250 million years ago, most life on Earth was wiped out in an extinction known as the "Great Dying." Geologists have learned that the end came slowly from thousands of centuries of volcanic activity.
