As has been predicted for some time, there is a physics train wreck coming at the semiconductor industry - a size and speed where atoms have reached their limits. Quantum computing has remained a dream for 20 years with little progress, which means chips will have to start getting bigger again, to get better performance - or we settle for playing Angry Birds.

The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with phase-change materials, which are capable of reversibly switching between two structural phases with different electrical states – one crystalline and conducting and the other glassy and insulating – in billionths of a second. 

Circular RNA were discovered a few years ago, but their role in our bodies is poorly understood. 

Our genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of our bodies. To express this genetic data, our DNA is copied into RNA molecules, which then translate the instructions into proteins that perform tasks in our cells. Several years ago, scientists discovered a new type of RNA molecule. Unlike all other known RNAs, this molecule is circular, and was labeled circular RNA.

Referrals for genetic testing more than doubled across the UK after actress Angelina Jolie announced in May that she proactively underwent a double mastectomy due to testing positive for a BRCA1 gene mutation.

The rise in referrals continued through to October, long after the announcement was made, according to findings in Breast Cancer Research.

The wage gap between government employees and the private sector is already large and growing. Now there will be a gap in benefits due to the Patient Protection and Affordable Care Act (AKA Obamacare) also.

Employees working for Fortune 500 companies can expect to pay higher employee contributions for their health insurance, according to a survey of chief human resource officer.

Patrick Wright, a professor in strategic human resource management at the University of South Carolina, directs the annual the HR@Moore Survey of Chief HR Officers. The survey is distributed to more than 560 CHROs of Fortune 500 companies and members of HR Policy Association, a professional organization. 

A new study uses tree rings to document arroyo evolution along the lower Rio Puerco and Chaco Wash in northern New Mexico.

Five years ago, it was good luck finding a hotel anywhere near the rural areas where natural gas extraction - fracking - was taking place.

The boom in natural gas meant a boom in employment and a boom in hotel rooms to keep workers. The wealth boosted Pennsylvania and other energy-dense states while most of the country remains mired in economic malaise. But over time people buy homes rather than rent hotel rooms and now there may be too many, says hospitality management scholars at Penn State.

"Demand is still high in many of the counties in the Marcellus Shale region, but the occupancy rate is starting to come down," says associate professor Daniel Mount. "The case could be made that this is a sign that hotels were overbuilt."
