Seeing the action
Researchers develop a novel device to image the minute forces and actions involved in cell membrane hemifusion.

A chip placed under the skin for more precise medicine
It's only a centimeter long, it's placed under your skin, it's powered by a patch on the surface of your skin and it communicates with your mobile phone. The new biosensor chip developed at EPFL is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs.

Changing diagnosis codes will challenge emergency medicine
Emergency medicine faces special challenges during this fall's changeover in how medical diagnoses are coded. Nearly a quarter of all ER clinical encounters could pose difficulties.

Cocaine addiction, craving and relapse
One of the major challenges of cocaine addiction is the high rate of relapse after periods of withdrawal and abstinence. But new research reveals that changes in our DNA during drug withdrawal may offer promising ways of developing more effective treatments for addiction. Withdrawal from drug use results in reprogramming of the genes in the brain that lead to addictive personality, say researchers from McGill University and Bar Ilan University in a new study published in the Journal of Neuroscience.

Possible overuse of anticoagulants, PCI outcomes studied using registry data
The American College of Cardiology's National Cardiovascular Data Registry was the source of data for seven studies published in the first four months of 2015, including a study that identified possible overuse of anticoagulants in low-risk atrial fibrillation patients and research that found a relationship between operator experience and outcomes in certain patients after percutaneous coronary intervention or angioplasty.

Breakthrough measures Parkinson's progression in the brain
University of Florida researchers have identified a biomarker that shows the progression of Parkinson's disease in the brain, opening the door to better diagnosis and treatment of the degenerative disease.

Supernovas help 'clean' galaxies
Recent research, led by Michigan State University astronomers, finds that the black holes located at the cores of galaxies launch fountains of charged particles, which can stir up gas throughout the galaxy and temporarily interrupt star formation. But unless something intervenes, the gas will eventually cool and start forming stars again.

Study connects credit default swaps to mortgage delinquencies
Researchers at The University of Texas at Dallas recently published the first empirical investigation connecting credit default swaps to mortgage defaults that helped lead to the 2007-2008 financial crisis.

How racial stereotypes impact the way we communicate
Racial stereotypes and expectations can impact the way we communicate and understand others, according to UBC research.The new study, published in the Journal of the Acoustical Society of America, highlights how non-verbal'"social cues' -- such as photographs of Chinese Canadians - can affect how we comprehend speech.

Better fine motor skills with delayed cord clamping
The importance of the umbilical cord not only for the foetus but for newborn infants too was shown by Swedish researchers several years ago, in a study that received great international acclaim. In a follow-up study in the journal JAMA Pediatrics they have now been able to show an association between delayed cord clamping (DCC) and children's fine motor skills at the age of four years, especially in boys.
