 Science{DISSERTATION} Astronomers spy 2 planets in tight quarters as they orbit a distant star A research team led the University of Washington and Harvard University has discovered a bigger version of Earth locked in an orbital tug-of-war with a much larger, Neptune-sized planet as they orbit very close to each other around the same star.

Science{DISSERTATION} Arctic climate more vulnerable than thought, maybe linked to Antarctic ice-sheet behavior "The polar regions are much more vulnerable to change than we thought before," say the project's Co-Chief scientists Martin Melles of the University of Cologne, Germany, Julie Brigham-Grette of the University of Massachusetts Amherst, US, and Pavel Minyuk of Russia's North-East Interdisciplinary Scientific Research Institute in Magadan.

{DISSERTATION} NHM entomologist wins grant to investigate mega-diverse insect order This week the NSF awarded a three-year $900,000 grant to co-investigators Drs. Brian Brown (Natural History Museum of Los Angeles County) and Art Borkent (Royal British Columbia Museum, Canada) to determine how many different species of flies live in a cloud forest in Costa Rica. Leading a team of 42 world experts, they will inventory a 100 by 200 meter area, and are estimating they will discover at least 3,000 species, many of them new to science.

Global Change Biology{DISSERTATION} Emperor penguins threatened by Antarctic sea ice loss A decline in the population of emperor penguins appears likely this century as climate change reduces Antarctic sea ice, according to a detailed projection published this week. The study concludes that the number of breeding pairs in a much-observed penguin colony may drop by about 80 percent by 2100.

Professional Geographer{DISSERTATION} Racial diversity increases, but segregation persists says Dartmouth geography professor While census data shows racial diversity is increasing in major cities across the United States, highly diverse neighborhoods are still rare, newly arrived immigrants continue to settle in concentrated residential patterns, and many African Americans remain concentrated in segregated neighborhoods, according to recent research by Richard Wright, professor of geography at Dartmouth College.

Current Biology{DISSERTATION} Out of the mouths of primates, facial mechanics of human speech may have evolved Two recent studies based at Princeton University suggest that the oral-facial component of human speech evolved from lip smacking, a friendly back-and-forth gesture performed by primates such as chimpanzees, baboons and macaques. The studies suggest a separate neural control for facial mechanics in primates that could help illuminate the neurological basis of speech disorders in humans.

Neuron{DISSERTATION} All things big and small: The brain's discerning taste for size Researchers at the MIT Computer Science and Artificial Intelligence Lab and the MIT Department of Brain and Cognitive Sciences have discovered that the brain organizes objects based on their physical size, with a specific region of the brain reserved for recognizing large objects and another reserved for small objects. Their findings could have major implications for fields like robotics, and could lead to a greater understanding of how the brain organizes and maps information.

Nature{DISSERTATION} Graphene is a tunable plasmonic medium With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called plasmons, using a simple electrical circuit. This is the first time anyone has observed plasmons on graphene, sheets of carbon just one atom thick, and an important step toward using plasmons to process and transmit information in spaces too tight to use light.

Science China Physics, Mechanics & Astronomy{DISSERTATION} Variable camber airfoil: New concept, new challenge A variable camber airfoil is an airfoil that changes camber to maximize its performance under radically different flight conditions. Little attention has been paid to the history of flow evolvement due to the camber deformation. In the 42nd issue of SCIENTIA SINICA, a paper distinguished the aerodynamic characteristics of a variable camber airfoil for steady and quasi-steady flow separation behaviors. Such distinction presents a new challenge to aircraft design.

Physical Review Letters{DISSERTATION} In nanotube growth, errors are not an option At the right temperature, with the right catalyst, there's no reason a perfect single-walled carbon nanotube 50,000 times thinner than a human hair can't be grown a meter long. That calculation is one result of a study by collaborators at Rice, Hong Kong Polytechnic and Tsinghua universities who explored the self-healing mechanism that could make such extraordinary growth possible.

{DISSERTATION} Univ. of Miami to lead team on grant for drought, flood prediction A multi-model seasonal climate prediction system can improve NOAA's operational forecasts in predicting severe floods or droughts, especially in south Florida. NOAA, NASA, NSF and the Department of Energy awarded a two-year grant of $1.9 M to a team led by University of Miami Professor Ben Kirtman. This new effort will expand on the group's work, establishing a comprehensive multi-model prediction available in real-time to all sectors of society.

ACS Nano{DISSERTATION} Study improves understanding of surface molecules in controlling size of gold nanoparticles North Carolina State University researchers have shown that the "bulkiness" of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles – with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.

Psychological Science{DISSERTATION} Research team finds knowledge of fractions and long division predicts long-term math success From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy. Yet, over the past 30 years, mathematics achievement of US high school students has remained stagnant -- and significantly behind many other countries, including China, Japan, Finland, the Netherlands and Canada. A research team led by Carnegie Mellon University's Robert Siegler has identified a major source of the gap -- US students' inadequate knowledge of fractions and division.

{DISSERTATION} MU researchers use sensor technologies to remotely monitor aging adults' health Technologies developed by University of Missouri researchers could help aging adults stay in their own homes longer while still being monitored by health care providers. University of Missouri researchers Marjorie Skubic and Marilyn Rantz have used motion-sensing technology to monitor changes in residents' health for several years at TigerPlace, an eldercare facility in Columbia. Now, they have received a grant from the National Science Foundation to expand their work to a facility in Cedar Falls, Iowa.

Thanks to a new microscopy technique, cell biology researchers can heed that same advice. University of Illinois researchers developed a method they call "trolling AFM," which allows them to study soft biological samples in liquid with high resolution and high quality by attaching a long, thin nanoneedle to the tip of the AFM probe, like trolling a fishing line.
