Making electrical contact along 1-D edge of 2-D materials
Dr. Cory Dean, assistant professor of physics at the City College of New York, is the lead author of a paper published today in the journal Science that demonstrates it is possible for an atomically thin two-dimensional material to have electrical contact along its one-dimensional edge. The contact architecture offers a new assembly technique for layered materials that prevents contamination at interfaces.

Cell Reports
Evolution of new species requires few genetic changes
Only a few genetic changes are needed to spur the evolution of new species -- even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately leading to fully genetically isolated species, report scientists from the University of Chicago in the Oct. 31 Cell Reports.

Global warming as viewed from the deep ocean
Yair Rosenthal of Rutgers, Braddock Linsley of Columbia University's Lamont-Doherty Earth Observatory, and Delia W. Oppo of the Woods Hole Oceanographic Institution, used the shells of tiny single-celled, bottom-dwelling foraminifera found in sediment cores to reconstruct the Pacific Ocean's heat content over the last 10,000 years. Their paper has been published in Science.

Racing sperm to boost results of in vitro fertilization
With a three-year, $293,000 award from the National Science Foundation, a research team led by Erkan Tüzel, assistant professor of physics at Worcester Polytechnic Institute, will use computer simulations to optimize the design of a microfluidic sperm-sorting chip developed at Brigham and Women's Hospital that races sperm through a microscopic obstacle course to select those most likely to successfully fertilize an egg -- a technique that may significantly improve the success of in vitro fertilization.

Listen up: Oysters may use sound to select a home
Oysters begin their lives as tiny drifters, but when they mature they settle on reefs. New research from North Carolina State University shows that the sounds of the reef may attract the young oysters, helping them locate their permanent home.

A first step in learning by imitation, baby brains respond to another's actions
Imitation may be the sincerest form of flattery for adults, but for babies it's their foremost tool for learning. Now researchers from the University of Washington and Temple University have found the first evidence revealing a key aspect of the brain processing that occurs in babies to allow this learning by observation.

Sex Roles
Eye tracking technology suggests people 'check out' women at first glance
Eye tracking technology has reconfirmed what women have known all along: that people look at their sexual body parts more and faces less when evaluating their appearance. The study, published today in Springer's journal Sex Roles, was led by Sarah Gervais of the University of Nebraska-Lincoln in the US. It found that especially women with typical hour glass figures or larger breasts, narrower waists, and bigger hips frequently prompted such gazes.

How poverty molds the brain
Groundbreaking research nearly two decades ago linking a mother's educational background to her children's literacy and cognitive abilities stands out among decades of social science studies demonstrating the adverse effects of poverty. Now new research conducted at Northwestern University has taken that finding in a neuroscientific direction: linking poor processing of auditory information in the adolescent brain to a lower maternal educational background.

Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago
A research team led by UC Riverside biogeochemists reports that oxygen-free and hydrogen sulfide-rich waters extended across roughly five percent of the ocean 93.9 million years ago -- far more than the modern ocean's 0.1 percent but much less than previous estimates for this event. Across this event, a major biological extinction in the marine realm took place. The new work shows that only portions of the ocean need to contain sulfide to greatly impact biota.

Crying wolf: Who benefits and when?
A crisis at work can bring out the best in colleagues, often inspiring more cooperation and self-sacrifice. A study from Indiana University and the University of Guelph has found that the benefits are not shared equally, with higher-ranking group members having the most to gain by perceived threats to the group.

Public wants labels for food nanotech -- and they're willing to pay for it
New research finds that people in the United States want labels on food products that use nanotechnology -- whether the nanotechnology is in the food or is used in food packaging. The research also shows that many people are willing to pay more for the labeling.

El Niño is becoming more active
A new approach to analyzing geological and biological clues from the past to reconstruct El Niņo activity during the past 600 years resolves disagreements and reveals that El Niņo has become more active in recent decades. The work, published in Climate of the Past by scientists from the University of New South Wales and the University of Hawaii International Pacific Research Center, may also help yield more accurate El Niņo projections with further global warming.

Scientists eye longer-term forecasts of US heat waves
Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The new research, led by scientists at NCAR, could potentially enable forecasts of the likelihood of US heat waves 15-20 days out, giving society more time to prepare for these often-deadly events.
