Meet the Titan supercomputer

post from Top stories on 30 October 2012 09:23:35 PM. © Top stories

The U.S. Department of Energy's (DOE) Oak Ridge National Laboratory launched a new era of scientific supercomputing today with Titan, a system capable of churning through more than 20,000 trillion calculations each second?or 20 petaflops?by employing a family of processors called graphic processing units first created for computer gaming. Titan will be 10 times more powerful than ORNL's last world-leading system, Jaguar, while overcoming power and space limitations inherent in the previous generation of high-performance computers.

New hope for prostate cancer patients

post from Top stories on 30 October 2012 09:19:57 PM. © Top stories

Scientists have discovered a molecular 'tell' in laboratory experiments that could help doctors determine the severity of a patient's prostate cancer.

Cancer of the prostate ? the most common male cancer in the UK ? presents in two distinct ways: a low-risk type, which may never cause any symptoms, and a high-risk form that needs treatment to prevent it spreading to other parts of the body.

Knowing which type of prostate cancer each patient has ? some 40,000 British men per year ? is therefore essential to ensuring they receive the correct treatment.

Animals learn to fine-tune their sniffs

post from Top stories on 30 October 2012 09:17:00 PM. © Top stories

Animals use their noses to focus their sense of smell, much the same way that humans focus their eyes, new research at the University of Chicago shows.

A research team studying rats found that animals adjust their sense of smell through sniffing techniques that bring scents to receptors in different parts of the nose. The sniffing patterns changed according to what kind of substance the rats were attempting to detect.

Schrödingers Quran a 2012 thought experiment

post from Top stories on 30 October 2012 09:13:44 PM. © Top stories

Whenever I see angry mobs reacting to the destruction of religious books it makes me think of Schrödinger, iPads and how we should interpret fundamentalist religious teachings in the digital era.

The brilliant Austrian physicist Erwin Schrödinger won the 1933 Nobel Prize for Physics for his contributions to quantum theory.

Purple shag Sun

The great astrophotographer Andre van der Hoeven sent me a shot he took of the Sun a few days ago. Looks like either Barney or the Grape Nehi folks paid it a visit:[Click to envioletenate.]Pretty cool. First, of course, the purple color is not real.[...]

NCBI ROFL: Hotspots for aggression in licensed
drinking venues.

post from Discoblog » NCBI ROFL on 30 October 2012 07:00:09 PM. © Discoblog » NCBI ROFL

“INTRODUCTION AND AIMS: In order to better understand the social context of barroom aggression, the aim was to identify common locations (‘hotspots’) for aggression in bars and examine the association of hotspots with aggression severity and environmental characteristics. DESIGN AND METHODS: Aggression hotspots were identified using narrative descriptions and data recorded on premises’ floor plans for 1057 incidents of aggression collected in the Safer Bars evaluation. Hierarchical Linear Modelling was used to identify bar-level and night-level characteristics associated with each hotspot. RESULTS: The most common location for aggression was the dance floor (20.0% of incidents) or near the dance floor (11.5%), followed by near the serving bar (15.7%), at tables (13.1%), aisles, hallways and other areas of movement (6.2%), entrance (4.5%) and the pool playing area (4.1%). Hotspots were predicted mainly by bar-level characteristics, with dance floor aggression associated with crowded bars, a high proportion of female and young patrons, lots of sexual activity, a large number of patrons and staff, security staff present, better monitoring and coordination by staff, and people hanging around at closing. Incidents at tables and pool tables tended to occur in bars with the opposite characteristics. Nightly variations in ...
