Fukushima Lesson: Prepare for Unanticipated Nuclear Accidents

ANN ARBOR, Mich.— A year after the crisis at Japan’s Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.

The First Spectroscopic Measurement of an Anti-Atom

*Berkeley Lab scientists helped build and operate the ALPHA antimatter trap at CERN, which has now probed the internal structure of the antihydrogen atom for the first time, taking the first step toward possible new insights into the difference between matter and antimatter*

The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Their results are reported in a forthcoming issue of Nature and are now online.

Ordinary hydrogen atoms are the most plentiful in the universe, and also the simplest – so simple, in fact, that some of the most fundamental physical constants have been discovered by measuring the tiny energy shifts resulting from the magnetic and electric interactions of hydrogen’s proton nucleus with its single orbiting electron.

New Method For Estimating Parameters May Boost Biological Models

Modeling biological systems can provide key insights for scientists and medical researchers, but periodic cycles that repeat themselves – so-called oscillatory systems – pose some key challenges. Researchers at North Carolina State University have developed a new method for estimating the parameters used in such models – which may advance modeling in research areas ranging from cancer to fertility.

NASA Mars Orbiter Catches Twister in Action

An afternoon whirlwind on Mars lofts a twisting column of dust more than half a mile (800 meters) high in an image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.

HiRISE captured the image on Feb. 16, 2012, while the orbiter passed over the Amazonis Planitia region of northern Mars. In the area observed, paths of many previous whirlwinds, or dust devils, are visible as streaks on the dusty surface. (more…)

What Makes Ticks Tick?

Durland Fish has researched ticks and their associated diseases for decades. A professor in the Division of Epidemiology of Microbial Diseases at the Yale School of Public Health, he has, among other things, contributed to the discovery that the bacterium that causes Lyme disease has European ancestry and that the disease, once nearly eradicated in North America, roared back with reforestation. More recently he helped develop a Lyme disease “app” for the iPhone and other Apple devices that provides users with detailed information about tick populations in any given area in the United States and even comes with a video on how to safely remove a tick. He has also worked on mosquito-borne West Nile virus and dengue fever. Students selected Fish as the school’s mentor of the year in 2010. (more…)

Hot Meets Cold at New Deep-Sea Ecosystem: “Hydrothermal Seep”

*Habitats overlap at Jaco Scar in depths off Costa Rica*

Decades ago, marine scientists made a startling discovery in the deep sea. They found environments known as hydrothermal vents, where hot water surges from the seafloor and life thrives without sunlight. (more…)

Cultural “Tightness” Can Hold Back Female Leadership – But not Always, Says University of Toronto Study

Normative support for equality can make the difference

Countries that more strictly uphold their cultural norms are less likely to promote women as leaders, unless those norms support equal opportunity for both sexes, shows a new paper from the University of Toronto’s Rotman School of Management.

“Cultural tightness can prevent the emergence of women leaders because tighter cultures may make a society’s people more resistant to changing the traditionally-held practice that placed men in leadership roles,” said Professor Soo Min Toh, who is cross-appointed to the Rotman School and the University of Toronto Mississauga, and co-wrote the paper with Professor Geoffrey Leonardelli at the Rotman School and U of T’s Department of Psychology.
