EAST LANSING, Mich. — The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by Michigan State University researchers to understand how molecules move energy around following the absorption of light. (more…)
ANN ARBOR, Mich.—They shook light from darkness. They coaxed something out of what we normally think of as nothing—the vacuum of space. And now their work has been named one of the top 10 breakthroughs of the year by Physics World, the international magazine announced today.
University of Michigan physics researcher Franco Nori is involved in the work, which was published in Nature in November.
The physicists directly observed, for the first time, light particles that flicker in and out of existence in the vacuum. They witnessed the long-predicted quantum mechanical phenomenon known as the dynamical Casimir effect. (more…)
Early close-ups of a Type Ia supernova allow Berkeley Lab scientists and their colleagues to picture its progenitor and infer how it exploded
Type Ia supernovae (SN Ia’s) are the extraordinarily bright and remarkably similar “standard candles” astronomers use to measure cosmic growth, a technique that in 1998 led to the discovery of dark energy – and 13 years later to a Nobel Prize, “for the discovery of the accelerating expansion of the universe.” The light from thousands of SN Ia’s has been studied, but until now their physics – how they detonate and what the star systems that produce them actually look like before they explode – has been educated guesswork.

*New “iLab” will allow undergraduate students to design projects in a 3-D environment*
COLUMBIA, Mo. – One of the most difficult tasks architects and interior designers face when designing buildings and rooms is visualizing exactly what their projects will look like when they are finished. Now, the University of Missouri architectural studies department has developed the Immersive Visualization Lab (iLab) to help students visualize their designs more accurately. Bimal Balakrishnan, an assistant professor of architectural studies in MU College of Human Environmental Sciences, says the iLab will be one of few labs in the country to allow undergraduate students to get hands-on experience using immersive 3-D technology to complete and test their designs as part of their design studio curriculum.
“Most university immersion labs are reserved primarily for graduate students to use for research purposes,” Balakrishnan said. “While the MU iLab will be used for research, it will also serve as an excellent teaching and experiential tool for undergraduate students.” (more…)
PASADENA, Calif. — NASA’s Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet’s surface, but they are the smallest exoplanets ever confirmed around a star like our sun.

Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA.
When a meteorite careens toward the dusty surface of the Red Planet, it kicks up dust and can cause avalanching even before the rock from outer space hits the ground, a research team led by an undergraduate student at the University of Arizona has discovered.
“We expected that some of the streaks of dust that we see on slopes are caused by seismic shaking during impact,” said Kaylan Burleigh, who led the research project. “We were surprised to find that it rather looks like shockwaves in the air trigger the avalanches even before the impact.” (more…)
Suppressing a newly identified protein involved in regulating cell division could be a novel strategy for fighting certain cancers because it stops the malignant cells from dividing and causes them to die quickly, according to a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center.
During the five-year study, designed to seek new targets for anti-cancer therapies, researchers discovered that depleting the protein, called STARD9, also helped the commonly used chemotherapy drug Taxol work more effectively against certain cancers. (more…)
AUSTIN, Texas — The efficiency of conventional solar cells could be significantly increased, according to new research on the mechanisms of solar energy conversion led by chemist Xiaoyang Zhu at The University of Texas at Austin. (more…)
