Rosetta data reveals more surprises about comet 67P
As the Rosetta spacecraft orbits comet 67P/Churyumov-Gerasimenko, an international team of scientists have discovered that the comet's atmosphere, or coma, is much less homogenous than expected and comet outgassing varies significantly over time, as reported in a paper published in the Jan. 23, 2015, issue of Science. Dr. Myrtha Hässig is lead author of the paper titled 'Time Variability and Heterogeneity in the Coma of 67P/Churyumov-Gerasimenko' and a postdoctoral researcher at Southwest Research Institute.

Enzymes believed to promote cancer actually suppress tumors
Upending decades-old dogma, a team of scientists at the University of California, San Diego School of Medicine say enzymes long categorized as promoting cancer are, in fact, tumor suppressors and that current clinical efforts to develop inhibitor-based drugs should instead focus on restoring the enzymes' activities.

Most endangered chimpanzees have complex evolutionary past, perilous future
Complementary analyses of population genetics, geographical distribution and habitat use paint a new picture of the evolutionary past and potentially bleak future of the Nigeria-Cameroon Chimpanzee (Pan troglodytes ellioti), already the most endangered chimp subspecies. There are unexpectedly two distinct populations of the Nigeria-Cameroon chimpanzee which have closer ties to their habitats than previously anticipated. And climate change could cause them significant and rapid harm.

Seeing is not remembering
People may have to 'turn on' their memories in order to remember even the simplest details of an experience, according to Penn State psychologists. This finding, which has been named 'attribute amnesia,' indicates that memory is far more selective than previously thought.

Next-generation sequencing offers insight into how species adapt to climate change
Next-generation sequencing allows for the creation and analysis of vast amounts of data about populations and their responses to shifting environmental conditions, including climate change. These data can provide fine-scale information at the genomic level into populations' adaptations to changing circumstances. Despite the potential usefulness of next-generation sequencing for environmental scientists, it is a costly tool, and funding has yet to equal the value that it may provide.

Scientists drilling first deep ice core at the South Pole
The 40,000-year record will be the first deep core from this part of Antarctica, and the first record longer than 3,000 years collected south of 82 degrees latitude. The exceptional cold at the South Pole preserves trace gases better than at other locations.

Greenland Ice: The warmer it gets the faster it melts
Melting of glacial ice will probably raise sea level around the globe, but how fast this melting will happen is uncertain. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster the ice will melt, according to computer model experiments by Penn State geoscientists.

Mapping the maize genome
Maize is one of the most important cereal crops in the world. The complete genome of maize has been sequenced, but its size and complexity presents a challenge to researchers seeking to identify specific genes responsible for traits. Positional cloning has been used successfully in smaller genomes; researchers have applied this mapping technique to the maize genome and have published their protocol -- the first detailed step-by-step protocol on positional cloning -- in Applications in Plant Sciences.

Climate change does not bode well for picky eaters
In a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently. New research published today suggests that how these species have adapted to co-exist with one another might be to blame.

Wearable sensor clears path to long-term EKG, EMG monitoring
Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiographyor electromyography. The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.

New laser for computer chips
Scientists from Forschungszentrum Juelich and the Paul Scherrer Institute in Switzerland in cooperation with international partners have presented the first semiconductor consisting solely of elements of main group IV. As a consequence, the germanium-tin laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.

New high-speed 3-D microscope -- SCAPE -- gives deeper view of living things
Columbia Engineering professor Elizabeth Hillman has developed SCAPE, a new microscope that images living things in 3-D at very high speeds. Her approach uses a simple, single-objective imaging geometry that requires no sample mounting or translation, making it possible to image freely moving living samples. SCAPE's ability to perform real-time 3-D imaging at cellular resolution in behaving organisms could be transformative for biomedical and neuroscience research.

As Austin grows, so does its traffic woes
The Network Modeling Center is a group within The University of Texas at Austin's Center for Transportation Research that is working with city planners in Austin to address traffic issues in the city. The NMC worked with experts at the Texas Advanced Computing Center to create a web visualization tool to display their models and speed up the traffic simulation time. The group uses their information to support city planners and build an informed community in improving existing infrastructure and developing new proposals.

Three nearly Earth-size planets found orbiting nearby star
NASA's Kepler Space Telescope has discovered a star with three planets only slightly larger than Earth. The outermost planet orbits in the 'Goldilocks' zone -- where surface temperatures could be moderate enough for liquid water and perhaps life to exist. The star ranks among the top 10 nearest stars known to have transiting planets. The star's close enough for astronomers to study the planets' atmospheres to determine if they could possibly be conducive to life.

Heart arrhythmias detected in deep-diving marine mammals
A new study of dolphins and seals shows that despite their remarkable adaptations to aquatic life, exercising while holding their breath remains a physiological challenge for marine mammals. The study, published Jan. 15 in Nature Communications, found a surprisingly high frequency of heart arrhythmias in bottlenose dolphins and Weddell seals during the deepest dives.
