New game to raise awareness of energy Posted: 11 Dec 2011 07:19 PM PST An energy quiz which tests people's knowledge of the amount of energy used by various devices and processes, such as leaving the lights switched on the Christmas tree, has now been developed.

Gene therapy achieves early success against hereditary bleeding disorder, study suggests Posted: 11 Dec 2011 10:44 AM PST Symptoms improved significantly in adults with the bleeding disorder hemophilia B following a single treatment with gene therapy.

B cell receptor inhibitor causes chronic lymphocytic leukemia remission Posted: 11 Dec 2011 10:40 AM PST A new, targeted approach to treating chronic lymphocytic leukemia has produced durable remissions in a Phase I/II clinical trial for patients with relapsed or resistant disease, researchers report.

Study may help physicians determine how patients will respond to immunomodulator therapy for multiple myeloma Posted: 11 Dec 2011 10:40 AM PST Research on the same protein that was a primary mediator of the birth defects caused by thalidomide now holds hope in the battle against multiple myeloma, new research suggests.

Multi-purpose photonic chip paves the way to programmable quantum processors Posted: 11 Dec 2011 10:40 AM PST A multi-purpose optical chip which generates, manipulates and measures entanglement and mixture -- two quantum phenomena which are essential driving forces for tomorrow's quantum computers -- has now been developed. This work represents an important step forward in the race to develop a quantum computer.

World's smallest steam engine: Heat engine measuring only a few micrometers works as well as its larger counterpart, although it sputters Posted: 11 Dec 2011 10:40 AM PST What would be a case for the repair shop for a car engine is completely normal for a micro engine. If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running. Researchers have now observed this with a heat engine on the micrometer scale. They have also determined that the machine does actually perform work, all things considered. Although this cannot be used as yet, the experiment shows that an engine does basically work, even if it is on the microscale. This means that there is nothing, in principle, to prevent the construction of highly efficient, small heat engines.

Breast cancer patients face increasing number of imaging visits before surgery Posted: 09 Dec 2011 04:39 PM PST Breast cancer patients frequently undergo imaging like mammograms or ultrasounds between their first breast cancer-related doctor visit and surgery to remove the tumor. Evaluations of these scans help physicians understand a person's disease and determine the best course of action. In recent years, however, imaging has increased in dramatic and significant ways, say researchers. More patients have repeat visits for imaging than they did 20 years ago.

Comprehensive view of the status of Atlantic bluefin tuna Posted: 09 Dec 2011 02:19 PM PST Bluefin populations on both sides of the Atlantic Ocean have declined precipitously since 1950, according to a new study. The model estimates the number of Atlantic bluefin tuna remaining in the ocean and projects future population sizes based on alternative management scenarios. The new model is revolutionary in its ability to account for population overlap (mixing) of this highly migratory animal on the North Atlantic foraging grounds.

Biker's warning! EPO hits blood vessels to raise blood pressure in the brain Posted: 09 Dec 2011 02:19 PM PST Erythropoietin might be considered a "performance enhancing" substance for athletes, but new research shows these enhancements cause increased risk of vascular problems in the brain. According to the study, short- or long-term use of EPO raises blood pressure by constricting arteries, which reduces the flow of blood to the brain. This finding also contradicts earlier evidence suggesting that EPO may be a viable early treatment for stroke victims.

Why women quit breast cancer drugs early: Side effects are so bad women end treatment and risk return of cancer, study finds Posted: 09 Dec 2011 02:19 PM PST Why do so many postmenopausal women who are treated for estrogen-sensitive breast cancer quit using drugs that help prevent the disease from recurring? The first study to ask the women themselves reports 36 percent of women quit early because of the medications' side effects, which are more severe and widespread than previously known. The research also reveals a big gap between what women tell their doctors about side effects and what they actually experience.

New solar-powered classroom brings science to schools in developing countries Posted: 09 Dec 2011 09:31 AM PST An innovative project is using solar generators to provide IT resources and 'hands-on' science for students in developing countries.

People with DFNA2 hearing loss show increased touch sensitivity, study shows Posted: 09 Dec 2011 07:57 AM PST People with a certain form of inherited hearing loss have increased sensitivity to low frequency vibration, according to a new study. The research findings reveal previously unknown relationships between hearing loss and touch sensitivity.

Ready-to-bake cookie dough not ready-to-eat, study of E. coli outbreak finds Posted: 09 Dec 2011 07:53 AM PST The investigation of a 2009 multistate outbreak of Shiga toxin-producing Escherichia coli, an important cause of bacterial gastrointestinal illness, led to a new culprit: ready-to-bake commercial prepackaged cookie dough.

Chronic pain in children and adolescents becoming more common Posted: 09 Dec 2011 07:51 AM PST Children who suffer from persistent or recurring chronic pain may miss school, withdraw from social activities, and are at risk of developing internalizing symptoms such as anxiety, in response to their pain. In the first comprehensive review of chronic pain in children and adolescents in 20 years, a group of researchers found that more children now are suffering from chronic pain and that girls suffer more frequently from chronic pain than boys.
