New Milky Way maps help solve stubborn interstellar material mystery
An international team of sky scholars has produced new maps of the material located between the stars in the Milky Way. The results should move astronomers closer to cracking a stardust puzzle that has vexed them for nearly a century.

Study of Chilean quake shows potential for future earthquake
Near real-time analysis of the April 1 earthquake in Iquique, Chile, showed that the 8.2 event occurred in a gap on the fault unruptured since 1877 and that the April event was not what the scientists had expected, according to an international team of geologists.

Molecular engineers record an electron's quantum behavior
A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light both to control the defect's entire quantum state and observe how that single electron state changes over time. The work appears in this week's online Science Express.

Lionfish characteristics make them more 'terminator' than predator
New research on the predatory nature of red lionfish, the invasive species that is decimating native fish populations in parts of the Caribbean Sea and Atlantic Ocean, seems to indicate that lionfish are not just a predator, but more like the 'terminator' of movie fame. In behavior that is called 'alarming,' it appears that in some cases lionfish will continue to hunt until the last fish of a local population is dead.

Inside the cell, an ocean of buffeting waves
Harvard-led researchers put forth a new model of the cytoplasm as a gel, not a liquid, and demonstrate that ATP-driven processes are indirectly responsible for transport within the cell. A measurement of the spectrum of forces exerted on the cytoplasm at any given time can provide a snapshot of the metabolic state of the cell.

Scientists use lasers to control mouse brain switchboard
Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions. The study may be a breakthrough in understanding how a critical part of the brain, called the thalamic reticular nucleus, influences consciousness.

Fukushima's legacy
Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds. A series of articles summarizing these studies has been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage.

Researchers identify a brain 'switchboard' important in attention and sleep
Researchers at NYU Langone Medical Center and elsewhere, using a mouse model, have recorded the activity of individual nerve cells in a small part of the brain that works as a 'switchboard,' directing signals coming from the outside world or internal memories. Because human brain disorders such as schizophrenia, autism, and post-traumatic stress disorder typically show disturbances in that switchboard, the investigators say the work suggests new strategies in understanding and treating them.

Novel chip-based platform could simplify measurements of single molecules
Researchers at UC Santa Cruz have developed a new approach for studying single molecules and nanoparticles by combining electrical and optical measurements on an integrated chip-based platform. In a paper published July 9 in Nano Letters, the researchers reported using the device to distinguish viruses from similarly sized nanoparticles with 100 percent fidelity.

New material could enhance fast and accurate DNA sequencing
Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process. Now, researchers at the University of Illinois at Urbana-Champaign have found that nanopores in the material molybdenum disulfide could sequence DNA more accurately, quickly and inexpensively than anything yet available.

New insights into the survival and transmission strategy of malaria parasites
Malaria parasites exploit the function of the epigenetic regulator HP1 to promote survival and transmission between human hosts, a new study shows. Using HP1 the parasite controls expression of surface antigens to escape immune responses in the infected victim. This prolongs survival of the parasite in the human blood stream and secures its transmission via mosquitoes. The study paves important avenues for new intervention strategies to prevent severe disease and malaria transmission.

Minke whales lunge 100 times/hour to feed under sea ice
Minke whales are one of the most common whales in Antartica, but also one of the most vulnerable. Little was known about how these small whales feed until Ari Friedlaender and colleagues attached tags to two animals that measured their movements showing that the whales do not need to be killed to study their feeding behaviour and that they perform over 100 lunges per hour under the sea ice.

Mouth bacteria can change its diet, supercomputers reveal
Mouth bacteria can change their metabolism in disease versus health. The Stampede and Lonestar supercomputers compared gene expression of 160,000 genes in healthy and diseased periodontal communities. Research paves way for biomarkers to predict illness from wide-ranging diseases such as periodontitis, diabetes, and Crohn's disease. The Stampede supercomputer is funded by the National Science Foundation through award ACI-1134872.
