Small male fish use high aggression strategy Posted: 31 Aug 2012 09:06 PM PDT In the deserts of central Australia lives a tough little fish known as the desert goby, and a new study is shedding light on the aggressive mating behaviour of smaller nest-holding males.

Exposure to common toxic substances could increase asthma symptoms Posted: 31 Aug 2012 05:34 PM PDT Children who are exposed to polychlorinated biphenyls (PCBs), which were commonly used in a range of industrial products, could be at risk of an increase in asthma symptoms, according to new research.

Earthquake hazards map study finds deadly flaws Posted: 31 Aug 2012 11:52 AM PDT Three of the largest and deadliest earthquakes in recent history occurred where earthquake hazard maps didn't predict massive quakes. Scientists have recently studied the reasons for the maps' failure to forecast these quakes. They also explored ways to improve the maps. Developing better hazard maps and alerting people to their limitations could potentially save lives and money in areas such as the New Madrid, Missouri fault zone.

A millimeter-scale, wirelessly powered cardiac device Posted: 31 Aug 2012 11:08 AM PDT Electrical engineers overturn existing models to demonstrate the feasibility of a millimeter-sized, wirelessly powered cardiac device. The findings, say the researchers, could dramatically alter the scale of medical devices implanted in the human body.

Hubble spots a supernova in NGC 5806 Posted: 31 Aug 2012 10:52 AM PDT A new image from the NASA/ESA Hubble Space Telescope shows NGC 5806, a spiral galaxy in the constellation Virgo (the Virgin). It lies around 80 million light years from Earth. Also visible in this image is a supernova explosion called SN 2004dg.

Potential drug for treatement of Alzheimer's disease investigated Posted: 31 Aug 2012 09:37 AM PDT A compound developed to treat neuropathic pain has shown potential as an innovative treatment for Alzheimer's disease, according to a new study.

Affluent people less likely to reach out to others in times of trouble? Posted: 31 Aug 2012 07:42 AM PDT Crises are said to bring people closer together. But a new study suggests that while the have-nots reach out to one another in times of trouble, the wealthy are more apt to find comfort in material possessions.

New, less expensive nanolithography technique developed Posted: 31 Aug 2012 07:41 AM PDT Researchers have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.

Danish scientists solve old blood mystery: New intriguing knowledge on blood hemoglobin Posted: 31 Aug 2012 07:41 AM PDT Scientists in Denmark have solved an old puzzle, which since the 1960s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when hemoglobin is released from red cells and becomes toxic. This toxic release of hemoglobin occurs in many diseases affecting red cell stability, e.g. malaria.

Breathable treatment to help prevent asthma attacks Posted: 31 Aug 2012 07:41 AM PDT Researchers in the UK are presenting details of a treatment that could help asthmatics fight infections that trigger 80 percent of asthma attacks.

The beat goes on: Research yields two 'firsts' regarding protein crucial to human cardiac function Posted: 31 Aug 2012 07:38 AM PDT Researchers have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat. Using an imaging method called atomic force microscopy, scientists have achieved two 'firsts': the first direct imaging of individual alpha-tropomyosin molecules and the first demonstrated examples of a measure of the human cardiac protein's flexibility.

Traumatic childhood may increase the risk of drug addiction Posted: 31 Aug 2012 05:34 AM PDT Previous research has shown that personality traits such as impulsivity or compulsiveness are indicators of an increased risk of addiction. Now, new research suggests that these impulsive and compulsive personality traits are also associated with a traumatic upbringing during childhood.

How gene profiling in emphysema is helping to find a cure Posted: 31 Aug 2012 05:33 AM PDT Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the United States and is thought to affect almost three million people in the UK. New research has identified genes whose activity is altered with increasing lung damage and, using a database of drug effects on gene activity (the Connectivity Map), finds that the compound Gly-His-Lys (GHK) affects the activity of these genes.

No more sneezing: Allergen-free house plants Posted: 31 Aug 2012 05:33 AM PDT New research shows how targeting two bacterial genes into an ornamental plant Pelargonium, can produce long-lived and pollen-free plants. Pelargoniums ('Geraniums' and 'Storkbills') have been cultivated in Europe since the17th century and are now one of the most popular garden and house plants around the world.

Too much protein HUWE1 causes intellectual disability Posted: 31 Aug 2012 05:33 AM PDT Two to three percent of children are born with an intellectual disability. Possibly by a genetic defect, but in 80 percent of these cases, we do not know -- yet -- which genes are responsible. Increased production of the HUWE1 protein is the cause in some patients, new research shows.

Immune system protein could explain pancreatitis Posted: 31 Aug 2012 05:33 AM PDT There is now a clear target for the treatment of acute pancreatitis, according to researchers in Sweden, who have discovered that a well-known protein plays a central role in the development of the disease. It is likely that the protein is also highly significant for other inflammatory diseases.

First implantation of prototype bionic eye with 24 electrodes: 'All of a sudden I could see a little flash of light' Posted: 31 Aug 2012 03:50 AM PDT In a major development, researchers in Australia have successfully performed the first implantation of an early prototype bionic eye with 24 electrodes. A patient with profound vision loss due to retinitis pigmentosa, an inherited condition, has now received the implant that enables her to experience some vision.

More heart problems with two chemo drugs for breast cancer, study suggests Posted: 30 Aug 2012 01:11 PM PDT Women who have breast cancer and are treated with two chemotherapy drugs may experience more cardiac problems like heart failure than shown in previous studies, according to a new study.
