Supercomputers Accelerate Development of Advanced Materials

Berkeley Lab helps develop a Google-like search engine for materials research.

New materials are crucial to building a clean energy economy—for everything from batteries to photovoltaics to lighter weight vehicles—but today the development cycle is too slow: around18 years from conception to commercialization. To speed up this process, a team of researchers from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts Institute of Technology (MIT) teamed up to develop a new tool, called the Materials Project, which launches this month.

Digging Up Clues: Research On Buried Blow Flies Will Help Crime Scene Investigators

When investigating a murder, every clue helps. New research from North Carolina State University sheds light on how – and whether – blow flies survive when buried underground during their development. It’s an advance that will help forensic investigators understand how long a body may have been left above ground before being buried – or possibly whether remains were moved from one grave to another.

“Blow flies are probably the most important insects to forensic entomology,” says Dr. Wes Watson, a professor of entomology at NC State and co-author of a paper describing the research. “They are usually the first insects to arrive after an animal – or a person – has died.” (more…)

Berkeley Lab to Build Cost Model for Fuel Cells

*A $2-million award from DOE will help bring down the cost of next-generation fuel cells.*

Fuel cells seem like an ideal energy source—they’re clean, efficient, silent and don’t require transmission lines. The hitch? They can be costly. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) hope to change that equation by building a sophisticated cost model that will take into account the total cost of ownership.

With a $2-million grant from the U.S. Department of Energy, a team of scientists led by Eric Masanet will perform a detailed assessment of fuel cell design and manufacturing that takes into account both intrinsic and external benefits. The aim is to quantify not only traditional manufacturing costs but also benefits that may previously have been overlooked and may ultimately bring down the cost of fuel cells. (more…)

The Genographic Project Confirms Humans Migrated Out of Africa through Arabia

New analytical method approaches the unstudied 99% of the human genome

WASHINGTON, D.C., – 02 Nov 2011: Evolutionary history shows that human populations likely originated in Africa, and the Genographic Project, the most extensive survey of human population genetic data to date, suggests where they went next. A study by the Project finds that modern humans migrated out of Africa via a southern route through Arabia, rather than a northern route by way of Egypt. These findings will be highlighted today at a conference at the National Geographic Society. (more…)

*Golden Membranes Pave the Way for a Better Understanding of Cancer and the Immune System*

Football has often been called “a game of inches,” but biology is a game of nanometers, where spatial differences of only a few nanometers can determine the fate of a cell – whether it lives or dies, remains normal or turns cancerous. Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new and better way to study the impact of spatial patterns on living cells.

Berkeley Lab chemist Jay Groves led a study in which artificial membranes made up of a fluid bilayer of lipid molecules were embedded with fixed arrays of gold nanoparticles to control the spacing of proteins and other cellular molecules placed on the membranes. This provided the researchers with an unprecedented opportunity to study how the spatial patterns of chemical and physical properties on membrane surfaces influence the behavior of cells. (more…)

NSF Announces Major Awards for Biodiversity Research, WHOI Scientists Selected

The 1977 discovery of deep-sea hydrothermal vent ecosystems that obtain energy through chemosynthesis rather than photosynthesis greatly expanded the perception of life on Earth. However, an understanding of their underlying microbiology and biogeochemistry still remains elusive.

A newly funded project, one of several major awards announced by the National Science Foundation’s (NSF) Dimensions in Biodiversity research program, stands to change that through a multi-disciplinary, international collaborative research effort led by Associate Scientist Stefan Sievert of the Woods Hole Oceanographic Institution.

Babies Understand Thought Process of Others at Ten Months Old, MU Research Finds

COLUMBIA, Mo. – New research from the University of Missouri indicates that at 10 months, babies start to understand another person’s thought process, providing new insights on how humans acquire knowledge and how communication develops.

“Understanding other people is a key factor in successful communication, and humans start to understand this at a very young age,” said Yuyan Luo, associate professor of developmental psychology in the MU College of Arts and Science. “Our study indicates that infants, even before they can verbally communicate, can understand the thought processes of other people – even if the thoughts diverge from what the infants know as truth, a term psychologists call false belief.” (more…)
