Sun Experience Seasonal Changes, NCAR Research Finds (Apr 29, 2015)
The Sun undergoes a type of seasonal variability, with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research (NCAR). This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth’s atmosphere.



Bounds on the Quantum Information "Speed Limit" Tightened (Apr 28, 2015)
Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards and Technology (NIST) have narrowed the theoretical limits for where that "speed limit" is. The research implies that quantum processors will work more slowly than some research has suggested. The work offers a better description of how quickly information can travel within a system built of quantum particles such as a group of individual atoms.

Compilers and More: The Past, Present and Future of Parallel Loops (Apr 26, 2015)
In parallel computing, we have been designing, describing, implementing and using parallel loops almost since the beginning. The advantage of parallel loops is that the parallelism scales up with the data set size or loop trip count. So, what exactly is a parallel loop? A sequential loop has a loop body and some kind of loop control: the program typically executes the loop body once, then the control code will determine whether to loop back to the top of the loop body and execute it again. Simil...

Changing the World One Hackathon at a Time (Apr 22, 2015)
Sixty-six teens are taking part in the My Brother's Keeper Hackathon, a group coding competition spearheaded by Qeyno Labs CEO Kalimah Priforce. Priforce notes this hackathon is different because it caters to African-American teens, rather than mostly white and Asian men. He says hackathons can collapse the walls that have isolated high-potential kids with too few opportunities. "Why not put Dr. King, Amelia Earhart and Steve Jobs in one room and see what is it they can do," Priforce says.



USC Team’s DNA Research is Shaping Up (Apr 21, 2015)
Remo Rohs is looking for some deep connections: He’s integrating genomics and structural biology to uncover some significant insights into how proteins recognize DNA. While genomics deciphers DNA by studying the sequences of base pairs that encode genetic information, structural biology explores the impact of the actual 3-D structure of DNA. Rohs, however, aims to unite the two fields into something new — and hopefully more useful.
