The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). Knowing the architecture of this protein, PRC2, for Polycomb Repressive Complex 2, should be a boon to its future use in the development of new and improved therapeutic drugs. (more…)

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.

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…)

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.
