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.

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.

Neuroscientists reach major milestone in whole-brain circuit mapping project

Posted: 01 Jun 2012 06:37 AM PDT

Neuroscientists have just reached an important milestone, publicly releasing the first installment out of 500 terabytes of data so far collected in their pathbreaking project to construct the first whole-brain wiring diagram of a vertebrate brain, that of the mouse.

Non-invasive brain stimulation shown to impact walking patterns

Kennedy Krieger researchers believe tool has potential to help patients relearn to walk after brain injury.

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.
