There appears to be an upper limit to how big the universe’s most massive black holes can get, according to new research led by Yale University astrophysicist Priyamvada Natarajan and Ezequiel Treister, a postdoctoral fellow at the University of Hawaii.

The University of Southampton is launching the world's largest-ever study of near-death experiences this week.

The AWARE (AWAreness during REsuscitation) study is to be launched by the Human Consciousness Project of the University of Southampton - an international collaboration of scientists and physicians who have joined forces to study the human brain, consciousness and clinical death.

The study is led by Dr Sam Parnia, an expert in the field of consciousness during clinical death, together with Dr Peter Fenwick and Professors Stephen Holgate and Robert Peveler of the University of Southampton. Following a successful 18-month pilot phase at selected hospitals in the UK, the study is now being expanded to include other centres within the UK, mainland Europe and North America.

Yeast, the essential microorganism for fermentation in the brewing of beer, converts carbohydrates into alcohol and other products that influence appearance, aroma, and taste. In a study published online today in Genome Research, researchers have identified the genomic origins of the lager yeast Saccharomyces pastorianus, which could help brewers to better control the brewing process.

For thousands of years, ale-type beers have been brewed with Saccharomyces cerevisiae (brewer's or baker's yeast). In contrast, lager beer, which utilizes fermentations carried out at much lower temperature than for ale, is a more recently developed alcoholic beverage, appearing in Bavaria near the end of the Middle Ages.

Arthroscopic surgery is widely accepted as an effective treatment for osteoarthritis of the knee. It's a minimally invasive surgical procedure involving insertion of an arthroscope and other instruments into the joint through small incisions in order to remove cartilage fragments and smooth the joint surfaces. Osteoarthritis is the most common form of arthritis affecting one in ten Canadians and 27 million Americans.

A landmark study conducted in London, Canada at The University of Western Ontario and Lawson Health Research Institute shows that a routinely practiced knee surgery is ineffective at reducing joint pain or improving joint function for sufferers of osteoarthritis. The study appears in the September 11th New England Journal of Medicine.

Burst Alert! March 19th was an exciting day for NASA. We know “why” it was special, but we don’t know “why why” it was special. They finally explain the why why today, and you can read all about it in Nature tomorrow. There was something amazing about GRB 080319B and the other cosmic bursts that NASA’s Swift satellite detected that day. (See NASA's animation of what they think happened). "Even by the standards of gamma-ray bursts, this burst was a whopper," says Swift lead scientist Neil Gehrels of NASA. "It blows away every gamma ray burst we’ve seen so far."
