 Science{DISSERTATION} A snapshot of pupfish evolution in action Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology.

Nature{DISSERTATION} Faulty behavior In an earthquake, ground motion is the result of waves emitted when the two sides of a fault move rapidly past each other. Not all fault segments move so quickly, however -- some slip slowly and are considered to be "stable." One hypothesis suggests that creeping fault behavior is persistent over time, with stable segments acting as barriers to fast-slipping earthquakes. But a new study by researchers at Caltech shows that this might not be true.

Evolution{DISSERTATION} Low extinction rates made California a refuge for diverse plant species The remarkable diversity of California's plant life is largely the result of low extinction rates over the past 45 million years, according to a new study. Although many new species have evolved in California, the rate at which plant lineages gave rise to new species has not been notably higher in California than elsewhere, researchers found.

BioScience{DISSERTATION} Whales' foraging strategies revealed by new technology Despite the many logistical difficulties of studying large whales, multisensor tags attached to the animals with suction cups are revealing their varied foraging techniques in unprecedented detail. These can be related to the animals' anatomy and to the distribution and behavior of their prey.

Physical Review Letters{DISSERTATION} DNA prefers to dive head first into nanopores A new study from Brown University researchers finds that DNA strands have a natural tendency to be pulled through nanopores headfirst. The research answers some fundamental questions about how DNA interacts with nanopores, which soon may enable lightning fast DNA analysis.

{DISSERTATION} Iowa State computer, electrical engineers working to help biologists cope with big data Iowa State computer and electrical engineers are developing computing tools to help biologists analyze all the data produced by today's research instruments. An initiative launched by the College of Engineering is helping the computer specialists build teams capable of solving the big data problems and competing for mult-million dollar research grants. To date, the initiative has attracted $5.5 million for four major research projects.

221st Meeting of the American Astronomical Society{DISSERTATION} Earth-size planets common in galaxy Last year, astronomers were excited to discover that the number of exoplanets increases towards smaller sizes, which suggests that there are many Earth-size planets in the galaxy. A new UC Berkeley and University of Hawaii analysis of three years of Kepler data shows that this increase stops around twice Earth size and holds for planets one to two times the diameter of Earth. Nevertheless, Earth-size planets occur around at least 17 percent of sun-like stars, they conclude.

Journal of Neuroscience{DISSERTATION} Study shows cognitive benefit of lifelong bilingualism Seniors who have spoken two languages since childhood are faster than single-language speakers at switching from one task to another, according to a study published in the Jan. 9 issue of The Journal of Neuroscience. Compared to their monolingual peers, lifelong bilinguals also show different patterns of brain activity when making the switch, the study found.

221st Meeting of the American Astronomical Society{DISSERTATION} Detecting dusty clouds and stars in our galaxy in a new way Northwestern University's Farhad Zadeh has discovered a new tool for detecting dusty clouds and stars in the center of the Milky Way galaxy: simply take a picture using radio waves. Unlike in the optical, X-ray and infrared wavelengths, it is unusual to see a dark feature with radio waves. Zadeh is the first to identify what he calls radio dark clouds and stars. Knowing details of these clouds is important because the clouds can produce stars.

Geology{DISSERTATION} Penn study shows mountains are only minor contributors to erosion and climate regulation For years, geologists believed that mountains, due to their steep slopes and high rates of erosion, were large contributors to the trapping of carbon in ocean sediment. But a new study led by the University of Pennsylvania's Jane Willenbring suggests that mountains do not play a significant role in this activity, turning a geological paradigm on its head.

221st Meeting of the American Astronomical Society{DISSERTATION} Massive outburst in neighbor galaxy surprises astronomers Astronomers making a long-term study of galaxies see sudden, energetic outburst in one of them. Still under observation, the outburst probably results from messy eating by a supermassive black hole.

Current Biology{DISSERTATION} Waste removal in worms reveals new mechanism to regulate calcium signaling Calcium is so much more than the mineral that makes our bones and teeth strong: It's a ubiquitous signaling molecule that provides crucial information inside of and between cells. Scientists have discovered a new way that calcium signaling may be controlled. In worms, a specific microRNA fine tunes such signaling, a finding that should be of great help to the thousands of scientists who study the important role of calcium signaling in health and disease.

Science{DISSERTATION} First meteorite linked to Martian crust After extensive analyses, researchers have identified a new class of Martian meteorite that likely originated from Mars's crust. It is also the only meteoritic sample dated to 2.1 billion years ago, the early era of the most recent geologic epoch on Mars. The meteorite contains an order of magnitude more water than any other Martian meteorite.

Science{DISSERTATION} Coral records suggest that recent El Nino activity rises above noisy background By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate cycle that affects climate worldwide. The new information will help assess the accuracy of climate model projections for 21st century climate change in the tropical Pacific.
