*Berkeley Lab Researchers Identify Structure of Key Control Element Behind Protein Misfolding That Can Lead to Disease*

The gold standard for nanotechnology is nature’s own proteins. These biomolecular nanomachines – macromolecules forged from peptide chains of amino acids – are able to fold themselves into a dazzling multitude of shapes and forms that enable them to carry out an equally dazzling multitude of functions fundamental to life. As important as protein folding is to virtually all biological systems, the mechanisms behind this process have remained a mystery. The fog, however, is being lifted.

A team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), using the exceptionally bright and powerful x-ray beams of the Advanced Light Source, have determined the crystal structure of a critical control element within chaperonin, the protein complex responsible for the correct folding of other proteins. The incorrect or “misfolding” of proteins has been linked to many diseases, including Alzheimer’s, Parkinson’s and some forms of cancer. (more…)

*ARPA-E funded project aims to produce fuel molecules in plant leaves*

Mention biofuels and most people think of corn ethanol. Some may think of advanced biofuels from switchgrass or miscanthus. But tobacco? Not likely.

That could change. A team of scientists led by a researcher from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is exploring a way to produce gasoline, diesel, and jet fuel from the iconic plant of the South. (more…)

Protecting People From Deadly Floods, Quakes in The Philippines

ANN ARBOR, Mich.— Typhoons thrash the Philippines every year, causing flash flooding and mudslides that often kill hundreds of people in the Southeast Asian nation. Many blame the death and destruction on the wrath of nature. But Gavin Shatkin has a different view.

“Disasters are not natural,” said Shatkin, an associate professor of urban planning at the University of Michigan. “They happen because of social structures.” (more…)

*Evidence Builds for White Shark Factor in Otter Mortality*

SANTA CRUZ, Calif. — The California or southern sea otter (Enhydra lutris nereis) appears to be experiencing an unprecedented increase in mortality from attacks by sharks, according to federal and state scientists.

Since 1968, biologists and veterinarians at the U.S. Geological Survey and California Department of Fish and Game have documented and examined all reported sea otter “strandings” — counting the number of dead, sick or injured sea otters recovered along California’s coast each year. (more…)

Project Aims To Improve HIV/AIDS Prevention Materials For African-American Women

African-American women make up a disproportionate number of HIV/AIDS cases in the United States. Researchers from North Carolina State University are trying to change that, leading a National Science Foundation project aimed at developing HIV/AIDS prevention materials that resonate with African-American female college students.

African-Americans represent approximately 14 percent of the U.S. population, but accounted for an estimated 44 percent of new HIV infections in 2009. The estimated rate of new HIV infections among African-American women was 15 times that of white women and over three times that of Latina women. (more…)

ANN ARBOR, Mich.— The fastest wind ever discovered blowing off a disk around a stellar-mass black hole has been observed by a team of astronomers that includes a University of Michigan doctoral student.

Using NASA’s Chandra X-ray Observatory, an orbiting telescope, they clocked the record-breaking super wind at about 20 million mph, or about 3 percent of the speed of light. This is nearly 10 times faster than astronomers had previously observed from a stellar-mass black hole. (more…)
