Increasing production and declining consumption of oil and gas have unexpectedly brought the United States markedly closer to a goal that has tantalized presidents since Richard Nixon: independence from foreign energy sources, a milestone that could reconfigure American foreign policy, the economy and more. In 2011, the country imported just 45 percent of the liquid…
In public forums about the drastic changes that higher ed may undergo in the coming years, one question inevitably gets asked of those advocating market disruption: Would the alternatives to the traditional degree pathway be good enough for their own children? The underlying concern in the question, of course, is that disruption in academe could…
Information security experts believe the blurring of the boundaries between computer and biological viruses is not too far-fetched—and could have very real consequences. The origins of each virus are strikingly different: A computer virus is designed, whereas a biological virus evolves under pressure from natural selection. But what would happen if these origins are switched?…
Every election year, political candidates of all stripes are called “knuckle-dragging Neanderthals.” In a recent column, Washington Post pundit Kathleen Parker asks if it’s fair that many U.S. women see the Republican party in precisely those terms. Barbara King’s question: Is that fair to the Neanderthals? King explains why Neanderthals weren’t at all the cartoonish,…
A layer of partially molten rock about 22 to 75 miles underground can’t be the only mechanism that allows continents to gradually shift their position over millions of years, according to a NASA-sponsored researcher. The result gives insight into what allows plate tectonics – the movement of the Earth’s crustal plates – to occur. Our…
Even if you think your voting decisions emerge from thoughtful considerations about each candidate’s strengths, studies show that superficial traits have powerful influences on us, too. From their height to the attractiveness of their facial features to the pitch of their voices, according to accumulating evidence, candidates win or lose based on far more than…
One giant step towards ‘creating a miniature star on Earth’
Mercury is even weirder than expected, NASA’s MESSENGER probe is showing. For starters, the planet’s interior is built differently than anything else scientists have blueprints for. Unlike Earth’s, Mercury’s core — which gobbles up 85 percent of the planet’s radius — consists of three layers instead of two. At the planet’s heart lies a probable…
In the 1940s, neurosurgeon Wilder Penfield found his patients would recall seemingly random information – the smell of cookies for instance – when he stimulated different brain areas with electric shocks. Two studies have now found evidence to support the memory storage theory that Penfield stumbled across. The research, in mice, even demonstrates that it…
Einstein’s theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale is so remote from current experimental capabilities that tests of quantum gravity are widely believed to be nearly impossible. Now an international…
