Atrial fibrillation: New management approaches for the 'new epidemic' in cardiovascular disease Posted: 26 Jun 2011 11:54 AM PDT According to the report, improvements in the management of AF can be achieved by several synergistic steps: the detection and better management of risk factors, good clinical use of new antithrombotic therapies, early detection of any new arrhythmia, and timely rhythm control treatment.

Hitting moving RNA drug targets: New way to search for novel drugs Posted: 26 Jun 2011 11:54 AM PDT By accounting for the floppy, fickle nature of RNA, researchers have developed a new way to search for drugs that target this important molecule.

New solar cell: Engineers crack full-spectrum solar challenge Posted: 26 Jun 2011 11:54 AM PDT Engineering researchers report a new solar cell that may pave the way to inexpensive coatings that efficiently convert the sun's rays to electricity.

Genome editing -- a next step in genetic therapy -- corrects hemophilia in animals Posted: 26 Jun 2011 11:53 AM PDT Using an innovative gene therapy technique called genome editing that hones in on the precise location of mutated DNA, scientists have treated the blood clotting disorder hemophilia in mice. This is the first time that genome editing, which precisely targets and repairs a genetic defect, has been done in a living animal and achieved clinically meaningful results.

Scientists pioneer nanoscale nuclear materials testing capability Posted: 26 Jun 2011 11:53 AM PDT A technique for testing irradiated materials on the nanoscale has yielded results on the macroscale. The technique uses electron microscopy with mechanical testing in situ; it could accelerate new materials for nuclear power applications and improve testing of nuclear power plants already in service.

Emissions from energy use in the water sector are poorly understood Posted: 26 Jun 2011 11:53 AM PDT Greater understanding is needed of greenhouse gas emissions from energy use in the water sector if it is to meet sustainability goals, according to researchers.

Ocean currents speed melting of Antarctic ice: A major glacier is undermined from below Posted: 26 Jun 2011 11:53 AM PDT Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study.

Scientists expose cancer cells' universal 'dark matter'; Findings reveal chaos in biochemical alterations of cancer cells Posted: 26 Jun 2011 11:53 AM PDT Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a team of researchers says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.

Genetic study shows that low body fat may not lower risk for heart disease and diabetes Posted: 26 Jun 2011 11:53 AM PDT Having a lower percentage of body fat may not always lower your risk for heart disease and diabetes, according to a new study.

Rogue blood cells may contribute to post-surgery organ damage Posted: 26 Jun 2011 11:53 AM PDT A study sheds new light on why people who experience serious trauma or go through major surgery, can suffer organ damage in parts of the body which are seemingly unconnected to the injury.

Premature aging caused by some HIV drugs, study shows Posted: 26 Jun 2011 11:52 AM PDT A class of anti-retroviral drugs commonly used to treat HIV, particularly in Africa and low income countries, can cause premature aging, according to new research. The study shows that the drugs damage DNA in the patient's mitochondria -- the 'batteries' which power their cells.

Prodigal plankton species makes first known migration from Pacific to Atlantic via Pole Posted: 26 Jun 2011 11:52 AM PDT Scientists say the melting Arctic has opened a Northwest Passage for Pacific species to enter the Atlantic, including a tiny plankton, unseen in the Atlantic for 800,000 years -- a return unwelcome due to its impact on the marine food web.

Promising results of Phase I diabetes trial Posted: 26 Jun 2011 11:52 AM PDT Medical researchers report promising results of the Phase I clinical trial of the generic drug BCG (bacillus Calmette-Guerin) to treat advanced type I diabetes.
