• 21:24 Hubble astronomers uncover an overheated early universe

  Read the story at ScienceDaily
  If you think global warming is bad, 11 billion years ago the entire universe underwent, well, universal warming. The consequence was that fierce blasts of radiation from voracious black holes stunted the growth of some small galaxies for a stretch of 500 million years. Astronomers used the Hubble Space Telescope's Cosmic Origins Spectrograph (COS) to identify an era, from 11.7 to 11.3 billion years ago, when the universe burned off a fog of primeval helium. This heated intergalactic gas was inhibited from gravitationally collapsing to form new generations of stars in some small galaxies.

• 07:23 Children, males and blacks are at increased risk for food allergies, study finds

  Read the story at ScienceDaily
  A new study estimates that 2.5 percent of the United States population, or about 7.6 million Americans, have food allergies. Food allergy rates were found to be higher for children, non-Hispanic blacks, and males, according to the researchers. The odds of male black children having food allergies were 4.4 times higher than others in the general population.

• 07:23 First clinical trial of gene therapy for muscular dystrophy lends insight into the disease

  Read the story at ScienceDaily
  A clinical trial designed to replace the genetic defect causing the most common form of muscular dystrophy has uncovered an unexpected aspect of the disease. The trial showed that some patients mount an immune response to the dystrophin protein even before they have received the gene therapy.

• 07:23 Stressed-out mums may worsen their child's asthma

  Read the story at ScienceDaily
  Mums who are often angry or irritated and those who suppress their emotional expressions can worsen the severity of their children's asthma symptoms, especially when the children are younger. Researchers studied 223 mothers for a year, investigating how their stress levels, coping styles and parenting styles were associated with their 2- to 12-year-old children's disease status.

  Read the story at ScienceDaily
  The exploration vessel Nautilus has discovered for the first time an area of reefs with deep-sea corals in the Mediterranean, offshore of Israel. This area apparently stretches over a few kilometers, 700 meters under the surface and some 30-40 km off the coast.

• 07:23 New computer modelling system predicts responses to HIV and AIDS treatments

  Read the story at ScienceDaily
  HIV-TRePS is a new system that predicts how an HIV patient will respond to different drug regimens, with an accuracy of around 80%. It is free to use, accessed over the Internet, and helps physicians choose the optimum combination of drugs for each patient.

• 07:23 BLADE software eliminates 'drive-by downloads' from malicious websites

  Read the story at ScienceDaily
  Researchers have developed a new tool that eliminates drive-by download threats. BLADE is browser-independent and when tested, it blocked all drive-by malware installation attempts from more than 1,900 malicious websites, produced no false positives and required minimal resources from the computer.

• 07:23 Immune system linked with accumulation of toxic tau protein

  Read the story at ScienceDaily
  Cells that help to protect the central nervous system may also contribute to pathological changes in the brain. New research provides mechanistic insight into a link between the immune system and neurodegenerative disorders like Alzheimer's disease that are associated with abnormal accumulation of tau protein.

• 07:23 Nature’s sights and sounds -- but not cityscapes and noise -- ease spinal pain during bone marrow extractions

  Read the story at ScienceDaily
  As the song says, a spoonful of sugar helps the medicine go down, and now researchers have found that the sights and sounds of chirping birds, ribbiting frogs and water trickling downstream can ease the substantial pain of bone marrow extraction in one of five people who must endure it.

• 07:22 Greatest warming is in the north, but biggest impact on life is in the tropics, new research shows

  Read the story at ScienceDaily
  New research adds to growing evidence that, even though the temperature increase associated with a warming climate has been smaller in the tropics, the impact of warming on life could be much greater there than in colder climates.

• 07:22 Fish near coal-fired power plants have lower levels of mercury

  Read the story at ScienceDaily
  Fish located near coal-fired power plants have lower levels of mercury than fish that live much further away. The surprising finding appears to be linked to high levels of another chemical, selenium, found near such facilities, which unfortunately poses problems of its own.

• 07:22 Light drinking during pregnancy: Harmful to child's behavioral or intellectual development?

  Read the story at ScienceDaily
  Light drinking during pregnancy does not harm a young child's behavioral or intellectual development, a new study in the UK suggests. In fact, researchers found that children born to light drinkers (consuming 1 to 2 drinks per week) were 30 percent less likely to have behavioral problems than children whose mothers did not drink during pregnancy.

• 07:22 Vultures use face flushing technique for instant status updates

  Read the story at ScienceDaily
  Tech savvy humans who use social media sites to instantly update their "statuses" may be behaving like vultures who use "face flushing" as a visible way of instantly updating their own status when interacting with peers and rivals. Research reveals how the ability to rapidly change skin color is a key form of interaction for vultures, especially for displays of dominance.

  Read the story at ScienceDaily
  Air pollution has already been linked to a range of health problems. Now, a ground-breaking new study suggests pollution from traffic may put women at risk for another deadly disease. The study links the risk of breast cancer -- the second leading cause of death from cancer in women -- to traffic-related air pollution.

  Read the story at ScienceDaily
  With the help of tiny, see-through fish, researchers are homing in on what happens in the brain while you sleep. In a new study, they show how the circadian clock and sleep affect the scope of neuron-to-neuron connections in a particular region of the brain, and they identified a gene that appears to regulate the number of these connections, called synapses.

  Read the story at ScienceDaily
  The ups and downs of the bacteria in an oil field provide a useful source of information for keeping tabs on the state of the oil field itself. In theory, this process known as 'biomonitoring' can increase the yield from an oil field.
