| Nanotechnology used to harness power of fireflies Posted: 15 Jun 2012 08:41 AM PDT Scientists have found a new way to harness the natural light produced by fireflies using nanoscience. Their breakthrough produces a system that is 20 to 30 times more efficient than those produced during previous experiments. |
| The boys are bad: Older male ants single out younger rivals for death squad Posted: 15 Jun 2012 07:45 AM PDT Male Cardiocondyla obscurior ants are diphenic (either winged or wingless). New research demonstrates that the dominant wingless (ergatoid) male is able to identify potential rivals before they emerge from their pupae. Constant patrolling of the nest ensures that this male is able to bite or chemically tag rivals as soon as they emerge from their pupae. Chemically tagged ants are quickly destroyed by workers. |
| Neutrons escaping to a parallel world? Posted: 15 Jun 2012 07:43 AM PDT In a new paper, researchers hypothesize the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter had been suggested in various scientific contexts some time ago, including the search for suitable dark matter candidates. |
| Studying soil to predict the future of Earth's atmosphere Posted: 15 Jun 2012 07:39 AM PDT Soil plays an important role in controlling the planet's atmospheric future according to new research. Researchers found that the interaction between plants and soils controls how ecosystems respond to rising levels of CO2 in the atmosphere. |
| Physicists predict success of movies at the box office based solely on advertising costs Posted: 15 Jun 2012 07:37 AM PDT A group of Japanese scientists have surprised themselves by being able to predict the success or failure of blockbuster movies at the box office using a set of mathematical models. The researchers used the effects of advertising and word-of-mouth communication to create a model that turned out to be successful in predicting how each movie fared once it hit the silver screen. The only data the researchers needed to put into the model were the daily advertisement costs of 25 movies that appeared in Japanese cinemas. |
| Breast milk kills HIV and blocks its oral transmission in humanized mouse Posted: 14 Jun 2012 03:27 PM PDT Although breastfeeding is attributed to a significant number of HIV infections in infants, most breastfed babies are not infected with HIV, despite prolonged and repeated exposure. HIV researchers have been left with a conundrum: does breast milk transmit the virus or protect against it? New research explores this paradox in a humanized mouse model, demonstrating that breast milk has a strong virus killing effect and protects against oral transmission of HIV. |

| Fish shed light on human melanoma Posted: 15 Jun 2012 05:46 PM PDT Zebrafish, a transparent member of the minnow family, are providing insight into human melanoma – a form of skin cancer – that may lead to new or repurposed drug treatments, for skin and other cancers. |
| Cancer's next magic bullet may be magic shotgun Posted: 15 Jun 2012 11:17 AM PDT A new approach to drug design promises to help identify future drugs to fight cancer and other diseases that will be more effective and have fewer side effects. |
| New surgery may reverse hand paralysis Posted: 15 Jun 2012 11:16 AM PDT A reconstructive neurosurgeon has pioneered a novel technique to restore hand function in patients with spinal cord injury. In a delicate four-hour procedure, he splices together tiny nerve endings, only one millimeter in width, to help restore hand mobility. |
| Genetic markers hope for new brain tumor treatments Posted: 15 Jun 2012 08:40 AM PDT Researchers have identified three sets of genetic markers that could potentially pave the way for new diagnostic tools for a deadly type of brain tumor that mainly targets children. |
| More to facial perception than meets the eye Posted: 15 Jun 2012 07:43 AM PDT People make complex judgments about a person from looking at their face that are based on a range of factors beyond simply their race and gender, according to new findings. |
| Active ingredient of cannabis has no effect on the progression of multiple sclerosis, study suggests Posted: 15 Jun 2012 07:39 AM PDT The first large non-commercial study to investigate whether the main active constituent of cannabis (tetrahydrocannabinol or THC) is effective in slowing the course of progressive multiple sclerosis shows that there is no evidence to suggest this; Although benefits were noted for those at the lower end of the disability scale. |
| BPA exposure effects may last for generations Posted: 15 Jun 2012 07:35 AM PDT Exposure to low doses of Bisphenol A (BPA) during gestation had immediate and long-lasting, trans-generational effects on the brain and social behaviors in mice, according to a recent study. |
| Persistence is learned from fathers, study suggests Posted: 15 Jun 2012 07:35 AM PDT A longitudinal study found that adolescents learn persistence through fathers who follow good parenting practices. As a result, these adolescents saw higher engagement in school and lower rates of delinquency. |
| Graphic warning labels improve smokers' recall of warning and health risks related to smoking Posted: 15 Jun 2012 07:35 AM PDT In a first of its kind study in the U.S., researchers have shown that the addition of graphic warning labels on cigarette packaging can improve smokers' recall of the warning and health risks associated with smoking. |
| Vitamin D with calcium shown to reduce mortality in elderly Posted: 15 Jun 2012 07:35 AM PDT A recent study suggests that vitamin D —- when taken with calcium —- can reduce the rate of mortality in seniors, therefore providing a possible means of increasing life expectancy. |
| Unexpected discovery highlights new role for cell death regulator Posted: 14 Jun 2012 03:27 PM PDT Scientists have already revealed the mechanism by which high alcohol intake can induce pancreatitis and its progression to pancreatic cancer.
