Science’s weirdest realm may be responsible for photosynthesis, our sense of smell, and even consciousness itself.

Graham Fleming sits down at an L-shaped lab bench, occupying a footprint about the size of two parking spaces. Alongside him, a couple of off-the-shelf lasers spit out pulses of light just millionths of a billionth of a second long. After snaking through a jagged path of mirrors and lenses, these minus­cule flashes disappear into a smoky black box containing proteins from green sulfur bacteria, which ordinarily obtain their energy and nourishment from the sun. Inside the black box, optics manufactured to billionths-of-a-meter precision detect something extraordinary: Within the bacterial proteins, dancing electrons make seemingly impossible leaps and appear to inhabit multiple places at once.

Physics may be the furthest thing from the minds of the presidential candidates right now, but a solid grasp of the science behind some of the latest headlines will be critical for the winner.

Physics has a history of intersecting with politics in ways both large and small, from the creation of the atomic bomb to nuclear meltdowns to terrorist methods. And now, with more specialized, high-tech issues to tackle than ever before, it is increasingly important that world leaders have an understanding of the underlying scientific concepts.

MIT researchers gauge the progress of malaria using a novel imaging technique.

Bridging physics, engineering, and microbiology, researchers at MIT have measured the frequency at which red blood cells vibrate and have shown that those frequencies reflect the health of the cells. The research could lead to better medical diagnostics. [ read more ]

A team of physicists in Vienna has devised experiments that may answer one of the enduring riddles of science: Do we create the world just by looking at it?

To enter the somewhat formidable Neo-Renaissance building at Boltzmanngasse 3 in Vienna, you must pass through a small door sawed from the original cathedrallike entrance. When I first visited this past March, it was chilly and overcast in the late afternoon. Atop several tall stories of scaffolding there were two men who would hardly have been visible from the street were it not for their sunrise-orange jumpsuits. As I was about to pass through the nested entrance, I heard a sudden rush of wind and felt a mist of winter drizzle. I glanced up. The veiled workers were power-washing away the building’s façade, down to the century-old brick underneath. [ read more ]

Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and fantasy buffs, cloaking devices that could render objects invisible to the human eye.
Two breakthroughs in the development of metamaterials - composite materials with extraordinary capabilities to bend electromagnetic waves - are reported separately this week in the Aug. 13 advanced online issue of Nature, and in the Aug. 15 issue of Science. [ read more ]
