A new study of gun violence in Chicago, led by Yale sociologist Andrew Papachristos, reveals that a person’s social network is a key predictor in whether an individual will become a victim of gun homicide, even more so than race, age, gender, poverty, or gang affiliation....

Quantum world record smashed

November 14, 2013 4:02 pm | by EurekAlert! | News | Comments

A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. An international team including Stephanie Simmons of Oxford University, UK, report in this week's Science....

Anti-counterfeit regulation (and the pressure on distributors) is intensifying

November 14, 2013 3:44 pm | by Anne Ting, Components Direct | Articles | Comments

The comment period for the proposed revisions to the Defense Federal Acquisition Regulation System (DFARS) ended on July 15, 2013. This important piece of legislation, which is expected to go into effect in the first quarter of 2014, is the culmination of several years of effort by lawmakers to deal with the problem of counterfeit electronic components.

Confronting climate change from the bottom up

November 14, 2013 3:25 pm | by Massachusetts Institute of Technology | News | Comments

As international climate negotiators meet this month for the 19th meeting of the UN Conference of Parties (COP19), there’s an increasing realization that top-down efforts to confront climate change aren’t working — or at least, they’re not working quickly enough. Are there ways that large groups of people — even a global community— could work together to take action now? That was the focus of an MIT climate conference last week, titled “Crowds an...

Nano magnets arise at 2-D boundaries

November 14, 2013 3:14 pm | by EurekAlert! | News | Comments

When you squeeze atoms, you don't get atom juice. You get magnets. According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise.


Distant artificial atoms cooperate by sharing light, international research team shows

November 14, 2013 3:06 pm | by EurekAlert! | News | Comments

An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment.

Photos of the Day: Next generation of biofuels is still years away

November 14, 2013 3:00 pm | by JONATHAN FAHEY, Associated Press | News | Comments

The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply, after years of broken promises and hype promoting a next-generation fuel source cleaner than oil. But as refineries churn out this so-called cellulosic fuel, it has become clear, even to the industry's allies, that the benefits remain, as ever, years away.

This NASA-inspired shower could lessen the global water crisis

November 14, 2013 12:28 pm | by Allegra Sparta, Editorial Intern | Blogs | Comments

Growing up in a rural area I learned to expect cries of “Turn that shower off, you’ll run the well dry!” while getting cleaned up for school. Having a well was the price you’d pay for living in the middle of nowhere, away from a reservoir-supplied water source. But apart from my teenage battles, a real problem lurks, one of global proportions.
