CU Mathematicians Show How Shallow Waves May Help Explain Tsunami Power
While wave watching is a favorite pastime of beachgoers, few notice what is happening in the shallowest water. A closer look by two University of Colorado Boulder applied mathematicians has led to the discovery of interacting X- and Y-shaped ocean waves that may help explain why some tsunamis are able to wreak so much havoc.
Professor Mark Ablowitz and doctoral student Douglas Baldwin repeatedly observed such wave interactions in ankle-deep water at both Nuevo Vallarta, Mexico, and Venice Beach, Calif., in the Pacific Ocean — interactions that were thought to be very rare but which actually happen every day near low tide. There they saw single, straight waves interacting with each other to form X- and Y-shaped waves as well as more complex wave structures, all predicted by mathematical equations, said Ablowitz.

Reading the Classics: It’s More than Just for Fun
EAST LANSING, Mich. — Reading a classic novel such as “Pride and Prejudice” can be entertaining, but, according to new research by a Michigan State University professor, it also can provide many other benefits beyond that.
Natalie Phillips, an MSU assistant professor of English, and her team placed study participants in an MRI machine and monitored their brain flow while reading the works of Jane Austen. (more…)
New Website Invites Public to Help Identify Seafloor Life and Habitats
The public is invited to help identify objects they see in images of the seafloor through a new interactive website called “Seafloor Explorer.” The result of a unique collaboration between oceanographers studying seafloor habitats, Web programmers and social scientists, Seafloor Explorer (www.seafloorexplorer.org) launches September 13.
The team has more than 40 million images, but are launching the site with a preliminary set of 100,000 – all of them taken by HabCam, a habitat mapping underwater vehicle. HabCam was developed and built by the HabCam group, which comprises marine biologists and engineers from the Woods Hole Oceanographic Institution (WHOI) as well as fishermen and other scientists. The Seafloor Explorer interactive website was funded by a grant from the Alfred P. Sloan Foundation, and built in collaboration with the HabCam Group by the Citizen Science Alliance (CSA), the developers behind interactive sites found on Zooniverse.org. (more…)
Nuclear Waste-Burning Technology Could Change the Face of Nuclear Energy
AUSTIN, Texas — University of Texas at Austin physicists have been awarded a U.S. patent for an invention that could someday be used to turn nuclear waste into fuel, thus removing the most dangerous forms of waste from the fuel cycle. (more…)
IBM Scientists First to Distinguish Individual Molecular Bonds
Atomic force microscopy helps scientists to reveal the bond order and length of bonds within molecules
Technique can be used to study future devices made from graphene
Zurich, Switzerland – 14 Sep 2012: IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM).
The results push the exploration of using molecules and atoms at the smallest scale and could be important for studying graphene devices, which are currently being explored by both industry and academia for applications including high-bandwidth wireless communication and electronic displays.

Relieving Plant Stress Could Eventually Help Humans Relax
EAST LANSING, Mich. — Humans could learn from how plants handle stress.
Federica Brandizzi, Michigan State University plant biologist, is using a grant from the National Institutes of Health to study how plants overcome stress as they grow. These pathways used to overcome stress are a key to growth. Without them plants, and animals, would die.
“When cells grow, they undergo trauma as growth is quite stressful,” Brandizzi said. “Since it’s very likely that these pathways have much in common between humans and plants, we should be able to gain insights into how plants and animals overcome stress and continue to grow as well.” (more…)
