Optical tweezers help researchers uncover key mechanics in cellular communication Posted: 01 Jun 2012 10:59 AM PDT By using a laser microbeam technology called optical tweezers, researchers have uncovered fundamental properties of the Notch network, a key molecular signaling system involved with development, cancer and cardiovascular disease.

Alcohol may trigger serious palpitations in heart patients Posted: 01 Jun 2012 10:56 AM PDT The term "holiday heart syndrome" was coined in a 1978 study to describe patients with atrial fibrillation who experienced a common and potentially dangerous form of heart palpitation after excessive drinking, which can be common during the winter holiday season. The symptoms usually went away when the revelers stopped drinking. Now new research builds on that finding, establishing a stronger causal link between alcohol consumption and serious palpitations in patients with atrial fibrillation, the most common form of arrhythmia.

How Does Exercise Affect Nerve Pain? Posted: 01 Jun 2012 09:05 AM PDT Exercise helps to alleviate pain related to nerve damage (neuropathic pain) by reducing levels of certain inflammation-promoting factors, suggests an experimental study.

Magnets May Help Prevent Rare Complication of Spinal Anesthesia Posted: 01 Jun 2012 09:05 AM PDT An simple technique using local anesthetic mixed with magnetized "ferrofluids" may provide a new approach to preventing a rare but serious complication of spinal anesthesia.

Open-fire cooking may affect child cognitive development Posted: 01 Jun 2012 07:38 AM PDT Children exposed to open-fire cooking in developing countries experience difficulty with memory, problem-solving and social skills. Research in the past decade has identified numerous health risks to children who are exposed regularly to smoke from open fires used in cooking. But until now, no one has associated smoke from cooking fires with deficits in cognitive development.

New method for picking the 'right' egg in IVF Posted: 01 Jun 2012 07:38 AM PDT Medical researchers have identified the chromosomal make-up of a human egg. This discovery may soon allow them to avoid using abnormal -- or aneuploid -- eggs during infertility treatments, and instead to pick eggs that are healthy enough for a successful in vitro fertilization (IVF) cycle.

Why is it so difficult to trace the origins of food poisoning outbreaks? Posted: 01 Jun 2012 07:38 AM PDT As illustrated by the 2011 E. coli outbreak in Germany, any delay in identifying the source of food poisoning outbreaks can cost lives and cause considerable political and economical damage. Scientists have now shown that difficulties in finding the sources of contamination behind food poisoning cases are inevitable due to the increasing complexity of a global food traffic network where food products are constantly crossing country borders, generating a worldwide network.

All proteins that bind to RNA, including 300 new ones, catalogued Posted: 01 Jun 2012 07:38 AM PDT Scientists have cataloged all proteins that bind to RNA, finding 300 previously unknown to do so. The study could help to explain the role of genes that have been linked to diseases like diabetes and glaucoma.

'Jack Spratt' diabetes gene identified Posted: 01 Jun 2012 07:38 AM PDT It has long been hypothesized that Type 2 diabetes in lean people is more "genetically driven." A new study has for the first time demonstrated that lean Type 2 diabetes patients have a larger genetic disposition to the disease than their obese counterparts. The study has also identified a new genetic factor associated only with lean diabetes sufferers.

Non-invasive brain stimulation shown to impact walking patterns Posted: 01 Jun 2012 06:31 AM PDT Kennedy Krieger researchers believe tool has potential to help patients relearn to walk after brain injury.

Producing artificial bones from fish scales Posted: 01 Jun 2012 06:30 AM PDT Scientists have developed technology for producing artificial bones from fish scales and apatite.

Nanotechnology breakthrough could dramatically improve medical tests Posted: 31 May 2012 01:57 PM PDT A laboratory test used to detect disease and perform biological research could be made more than 3 million times more sensitive, according to researchers who combined standard biological tools with a breakthrough in nanotechnology.

First success of targeted therapyin most common genetic subtype of non-small cell lung cancer Posted: 31 May 2012 10:54 AM PDT A novel compound has become the first targeted therapy to benefit patients with the most common genetic subtype of lung cancer.

Hiding true self at work can result in less job satisfaction, greater turnover Posted: 31 May 2012 08:24 AM PDT Hiding your true social identity -- race and ethnicity, gender, age, religion, sexual orientation or a disability -- at work can result in decreased job satisfaction and increased turnover, according to a new study.
