New study of storm generation could improve rainfall prediction in West Africa
A new study of how storms are generated could improve rainfall prediction in dry regions of Africa, where drought and short growing seasons are common.

Bariatric surgery among older, high-risk patients not associated with reduced mortality
The use of bariatric surgery among older, severely obese patients was not associated with a decreased risk of death, according to a study in the June 15 issue of JAMA.

Researchers improve method for finding genetic mistakes that fuel cancer
A dramatically better computer tool for finding the genetic missteps that fuel cancer has been developed by St.

We are all mutants
How many new mutations does a child have and did most of them come from mum or dad?

Heart attack death rates linked to ambulance diversion
Heart attack patients die at a higher rate when their nearest emergency room is so overtaxed that the ambulance transporting them is dispatched to another hospital, according to a new study led by scientists at the University of California, San Francisco.

Single GFP-expressing cell is basis of living laser device
Two investigators at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a device in which a single cell genetically engineered to express green fluorescent protein is used to amplify the light particles called photons into nanosecond-long pulses of laser light.

UCL grows first telecommunications wavelength quantum dot laser on a silicon substrate
A new generation of high speed, silicon-based information technology has been brought a step closer by researchers in the Department of Electronic and Electrical Engineering at UCL and the London Centre for Nanotechnology.

Diversion of ambulances associated with increased risk of death for heart-attack patients
Among Medicare patients with heart attack in 4 California counties, diversion of ambulance traffic by the nearest emergency department for 12 hours or more was associated with an increased risk of death for up to one year, according to a study in the June 15 issue of JAMA.

Important monitoring of heart performance is omitted in two-thirds of high-risk surgical operations
Only 35 percent of anesthesiologists are carrying out a simple procedure during high-risk surgery that can make a significant impact on how well patients recover from their operations, according to new research presented on Sunday, June 12, at the European Anaesthesiology Congress in Amsterdam.

Family genetic research reveals the speed of human mutation
A team of researchers have discovered that, on average, thirty mutations are transmitted from each parent to their child, revising previous estimations and revolutionizing the timescale we use to calculate the number of generations separating us from other species.
