Duke wins $15 million renewal to study nanotech safety
A pioneering, multi-institution research center headquartered at Duke's Pratt School of Engineering has just won a $15-million grant renewal from the National Science Foundation and the US Environmental Protection Agency to continue learning more about where nanoparticles accumulate, how they interact with other chemicals and how they affect the environment.

Penn and Drexel team demonstrates new paradigm for solar cell construction
Researchers from the University of Pennsylvania and Drexel University have experimentally demonstrated a new paradigm for solar cell construction which may ultimately make them less expensive, easier to manufacture and more efficient at harvesting energy from the sun.

Researchers at Penn add another tool in their directed assembly toolkit
An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles. Now, the Penn team has added another tool to this directed assembly toolkit.

Penn team elucidates evolution of bitter taste sensitivity
People often have strong negative reactions to bitter substances, which, though found in healthful foods like vegetables, can also signify toxicity. For this reason, the ability to sense bitterness likely played an important role in human evolution. A new study by University of Pennsylvania scientists suggests that a genetic mutation that makes certain people sensitive to the taste of a bitter compound appears to have been advantageous for certain human populations in Africa.

Feast and famine on the abyssal plain
Marine biologists have long been puzzled by the fact that marine snow does not supply enough food to support all the animals and microbes living in deep-sea sediments. A new paper by MBARI researcher Ken Smith and his colleagues shows that blooms of algae or animals near the sea surface can deliver as much food to deep-sea organisms as would normally arrive over years or even decades.

Bacteria may allow animals to send quick, voluminous messages
Twitter clips human thoughts to a mere 140 characters. Animals' scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them. In the current issue of the Proceedings of the National Academies of Science, a Michigan State University researcher shows that the detailed scent posts of hyenas are, in part, products of symbiotic bacteria, microbes that have a mutually beneficial relationship with their hosts.

Methane-munching microorganisms meddle with metals
A pair of microbes on the ocean floor "eats" methane in a unique way, and a new study provides insights into their surprising nutritional requirements. Learning how these methane-munching organisms make a living in these extreme environments could provide clues about how the deep-sea environment might change in a warming world.

Levitating foam liquid under the spell of magnetic fields
Foams fascinate, partly due to their short lifespan. Foams change as fluid drains out of their structure over time. It is precisely their ephemeral nature which has, until now, prevented scientists from experimentally probing their characteristic dynamics further. Instead, foams have often been studied theoretically. Now, researchers have devised a method of keeping foams in shape using a magnet, which allows their dynamics to be investigated experimentally, as recently described in EPJ E.

Single-cell genome sequencing gets better
Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. Preliminary data suggest that individual neurons from the same brain have different genetic compositions. The breakthrough, published in Nature Biotechnology, comes from a new single-cell genome sequencing technique that confines genome amplification to fluid-filled wells with a volume of just 12 nanoliters.

'Tiger stripes' underneath Antarctic glaciers slow the flow
Researchers at Princeton University and the British Antarctic Survey have discovered that most resistance to the movement of glaciers over the underlying bedrock comes from narrow, high-friction stripes that lie within large, extremely slippery areas underneath the glacier. These stripes are thought to govern the speed at which Antarctic glaciers are moving.

Cost-effective method accurately orders DNA sequencing along entire chromosomes
A new computational method has been shown to quickly assign, order and orient DNA sequencing information along entire chromosomes. The method may help overcome a major obstacle that has delayed progress in designing rapid, low-cost -- but still accurate -- ways to assemble genomes from scratch. Data gleaned through this new method can also validate certain types of chromosomal abnormalities in cancer.

UNH, UC Davis launch network to study environmental microbes
A grant to the University of New Hampshire and the University of California, Davis, will help biologists identify an abundant yet largely unknown category of organisms, leading to better understanding of the vital environmental functions they play. The National Science Foundation awarded the universities $500,000 to develop a Research Coordination Network on eukaryotic biodiversity. The work will apply new genome sequencing technology to study and classify microscopic eukaryote species like nematodes, fungi, and single-celled animals.

Carnegie Mellon researchers use inkblots to improve security of online passwords
Carnegie Mellon University computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA (Generating panOptic Turing Tests to Tell Computers and Humans Apart), would be suitable for protecting high-value accounts, such as bank accounts, medical records and other sensitive information.

NSF awards Chicago Botanic Garden $1.54 million Dimensions in Biodiversity grant
Chicago Botanic Garden researchers have received a $1.54 million NSF Dimensions in Biodiversity grant to study the role floral scent, pollinators and flower predators play in driving plant evolution. The grant program is a "race against time" to grasp the scope and role of life on earth, according to the NSF. The research will focus on evening primroses in the western United States; their pollinators, hawkmoths; and their predators, Mompha moths.

Arizona State University is teaming up with seven other research universities to establish a new Science and Technology Center, sponsored by the National Science Foundation with an initial five-year, $25-million grant (extendable for another five years). The center will be based at the University at Buffalo. It is expected to transform the field of structural and dynamic molecular biology, including drug development, by using X-ray lasers to peer into biological molecules.

From 1 collapsing star, 2 black holes form and fuse
Over billions of years, small black holes can slowly grow into supermassive black holes by taking on mass from their surroundings, and also by merging with other black holes. But this slow process can't explain how supermassive black holes existing in the early universe would have formed less than one billion years after the Big Bang. New findings from a group of Caltech researchers help to test a model that solves this problem.
