 ACS NanoLight-carved 'nano-volcanoes' hold promise for drug delivery Researchers from North Carolina State University have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies.

PLOS ONE'Tailing' spiny lobster larvae to protect them In a new study of spiny lobsters scientists from the University of Miami and Old Dominion studied the larval dispersal of this species in the Caribbean. The goal of the study was to describe the sources, sinks, and routes connecting the Caribbean spiny lobster metapopulation. The results led the team to propose marine resource management strategies that incorporate larval connectivity and "larval lobster credits" to sustain and rebuild exploited marine populations.

Journal of the American Chemical Society'Self-cleaning' pollution-control technology could do more harm than good, study suggests Research by Indiana University environmental scientists shows that air-pollution-removal technology used in "self-cleaning" paints and building surfaces may actually cause more problems than they solve. The study finds that titanium dioxide coatings, seen as promising for their role in breaking down airborne pollutants on contact, are likely in real-world conditions to convert abundant ammonia to nitrogen oxide, the key precursor of harmful ozone pollution.

ScienceStudy: Context crucial when it comes to mutations in genetic evolution New research led by evolutionary biologist Jay Storz of the University of Nebraska-Lincoln has found that whether a given mutation is good or bad is often determined by other mutations associated with it. In other words, genetic evolution is context-dependent.

Nature CommunicationsQuestions rise about seeding for ocean C02 sequestration A study suggests that iron fertilization, the process of putting iron into the ocean to encourage the growth of C02 capturing alga blooms, could backfire.

Proceedings of the Royal Society BResearch shows male guppies reproduce even after death Performing experiments in a river in Trinidad, evolutionary biologist David Reznick at the University of California, Riverside and colleagues have found that male guppies -- small freshwater fish -- continue to reproduce for at least ten months after they die, living on as stored sperm in females, who have much longer lifespans than males. While it is well known that guppies store sperm, Reznick and his team had never before thought of the extent of the storage.

Nature CommunicationsMoving iron in Antarctica Georgia Tech research published online in Nature Communications indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there's not enough iron to go around, and the added iron during fertilization experiments may stimulate less productivity than expected.

Computer Vision and Pattern Recognition ConferenceCarnegie Mellon method uses network of cameras to track people in complex indoor settings Researchers at Carnegie Mellon University have developed a method for tracking the locations of multiple individuals in complex, indoor settings using a network of video cameras, creating something similar to the fictional Marauder's Map used by Harry Potter to track comings and goings at the Hogwarts School. The method was able to automatically follow the movements of 13 people within a nursing home, even though individuals sometimes slipped out of view of the cameras.

Proceedings of the National Academy of SciencesAfrican starlings: Dashing darlings of the bird world in more ways than 1 It's not going to happen while you're peering through your binoculars, but African glossy starlings change color more than 10 times faster than their ancestors and even their modern relatives, say researchers at The University of Akron and Columbia University. The changes have led to new species of birds with color combinations previously unseen, according to a study published today in the Proceedings of the National Academy of Sciences USA.

Proceedings of the National Academy of SciencesFrom hot springs to HIV, same protein complexes are hijacked to promote viruses Biologists from Indiana University and Montana State University have discovered a striking connection between viruses such as HIV and Ebola and viruses that infect organisms called archaea that grow in volcanic hot springs. Despite the huge difference in environments and a two billion year evolutionary time span between archaea and humans, the viruses hijack the same set of proteins to break out of infected cells.

Proceedings of the National Academy of SciencesBridge species drive tropical engine of biodiversity Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear. New research sheds light on how that pattern came about. Furthermore, it confirms that the tropics have been and continue to be the Earth's engine of biodiversity.

Second Joint Conference on Lexical and Computational SemanticsWhen will my computer understand me? For more than 50 years, linguists and computer scientists have tried to get computers to understand human language by programming semantics as software, with mixed results. Enabled by supercomputers at the Texas Advanced Computing Center, University of Texas researchers are using new methods to more accurately represent language so computers can interpret it. Recently, they were awarded a grant from DARPA to combine distributional, high dimensional space representation of word meanings with Markov logic networks to better capture human understanding of language.

Cancer CellUni Basel researchers discover master regulator in cancer metastasis In the process of metastasis, the movement of cancer cells to different parts of the body, a specific master regulator gene plays a central role: a transcription factor named Sox4 activates a sequence of genes and triggers the formidable process. This finding is reported by researchers from the University of Basel and from the Friedrich Miescher Institute in Cancer Cell. Inhibition of Sox4 and subsequent processes may prevent metastasis in cancer patients.

Proceedings of the National Academy of SciencesLarge-scale biodiversity is vital to maintain ecosystem health Over the years ecologists have shown how biological diversity benefits the health of small, natural communities. New analysis by ecologists at UC Santa Cruz demonstrates that even higher levels of biological diversity are necessary to maintain ecosystem health in larger landscapes over long periods of time.

Geophysical Research LettersPollution in Northern Hemisphere helped cause 1980s African drought Air pollution in the Northern Hemisphere in the mid-20th century cooled the upper half of the planet and pushed rain bands south, contributing to the prolonged and worsening drought in Africa's Sahel region. Clean air legislation in the 1980s reversed the trend and the drought lessened.

Their findings, which appear in the Journal of Experimental Social Psychology, suggest that there is a link between political ideology and racial categorization.

Angewandte Chemie International EditionPromising material for lithium-ion batteries Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. The electrode material has a decisive influence on a battery's capacity. So far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. Scientists at the Technische Universitaet Muenchen have now developed a material made of boron and silicon that could smooth the way to systems with higher capacities.
