• 06:00 What's causing life-threatening blood clots in brain surgery patients?

  Read the story at EurekAlert
  One of the most severe complications of brain surgery is a pulmonary embolism. But a study in the Journal of Neurosurgery suggests that screening methods used to access the risk of pulmonary embolisms may fall short.

• 04:22 Strain-gating piezotronics: New class of piezoelectric logic devices created using zinc oxide nanowires

  Read the story at ScienceDaily
  Researchers have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires.

• 04:22 Water in Earth's mantle key to survival of oldest continents

  Read the story at ScienceDaily
  Earth today is one of the most active planets in the Solar System, and was probably even more so during the early stages of its life. Thanks to the plate tectonics that continue to shape our planet's surface, remnants of crust from Earth's formative years are rare, but not impossible to find. A new paper examines how some ancient rocks have resisted being recycled into Earth's convecting interior.

• 04:22 Drugs used to treat osteoporosis not linked with higher risk of esophageal cancer

  Read the story at ScienceDaily
  Although some reports have suggested a link between the use of oral bisphosphonates (drugs that prevent the loss of bone mass) and esophageal cancer, analysis of medical data from more than 80,000 patients in the United Kingdom found that use of these drugs was not significantly associated with new cases of esophageal or gastric cancer, according to a new study.

• 04:22 Cuckoo chicks in Zebra finches: Eggs from other females can be found in every fifth nest

  Read the story at ScienceDaily
  Some female zebra finches foist a part of their eggs on their neighbors. Scientists in Germany have discovered that in every fifth nest there is one egg that is not produced by its social parents. The female birds act in a very well-targeted way: eggs are being placed in “foster-care” shortly before the hosts commence their own egg laying.

• 04:22 Long term use of oral bisphosphonates may double risk of esophageal cancer, study finds

  Read the story at ScienceDaily
  People who take oral bisphosphonates for bone disease over five years may be doubling their risk of developing esophageal cancer (cancer of the gullet), according to a new study.

• 04:22 Value of oxygen therapy in end-of-life care challenged in new study

  Read the story at ScienceDaily
  Millions of patients with advanced disease in palliative care settings receive oxygen therapy to help them breathe more easily. But a new study says roughly half of them don't benefit from the intervention, and among those who do benefit, it doesn't make a bit of difference whether they get pure oxygen or just plain old room air -- both offer equal benefit.

• 04:22 New warning signs may predict kidney transplant failure

  Read the story at ScienceDaily
  Kidney transplants that show a combination of fibrosis (scarring) and inflammation after one year are at higher risk of long-term transplant failure, according to a new study.

• 04:22 Cigarette smoke may contribute to lung inflammation through a new chemical pathway

  Read the story at ScienceDaily
  Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to new findings. Researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation.

• 04:22 Social networks influence health behaviors

  Read the story at ScienceDaily
  Individuals are more likely to acquire new health practices while living in networks with dense clusters of connections -- that is, when in close contact with people they already know well.

• 04:22 Children who eat vended snack foods face chronic health problems, poor diet, study finds

  Read the story at ScienceDaily
  School children who consume foods purchased in vending machines are more likely to develop poor diet quality -- and that may be associated with being overweight, obese or at risk for chronic health problems such as diabetes and coronary artery disease, according to new research.

• 04:22 Experiment records ultrafast chemical reaction with vibrational echoes

  Read the story at ScienceDaily
  To watch a magician transform a vase of flowers into a rabbit, it's best to have a front-row seat. Likewise, for chemical transformations in solution, the best view belongs to the molecular spectators closest to the action. Those special molecules comprise the "first solvation shell," and although it has been known for decades that they can sense and dictate the fate of nearly every chemical reaction, it has been virtually impossible to watch them respond -- until now.

• 04:22 Science's policy clout diminished, but oil risk looms large, study finds

  Read the story at ScienceDaily
  More people are likely to believe scientific studies claiming that oil drilling is riskier, not safer, than was previously thought, according to a new study of attitudes in California. What's more the findings show that scientists' efforts to influence public opinion have a limited effect.

  Read the story at ScienceDaily
  Thousands of people who are partially sighted following stroke or brain injury could gain greater independence from a simple, cheap and accessible training course which could eventually be delivered from their mobile phones or hand-held games consoles, according to a new study.

  Read the story at ScienceDaily
  A research team has shown for the first time that a gene called Myc, which is traditionally thought of as a cancer-causing gene, may be far more important in the development and persistence of stem cells than was known before.
