CAMBRIDGE, MA -- Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech. Researchers from MIT and several European universities have shown that the human version of a gene called Foxp2 makes it easier to transform new experiences into routine procedures. When they engineered mice to express humanized Foxp2, the mice learned to run a maze much more quickly than normal mice. The findings suggest that Foxp2 may help humans with a key component of learning language ...

Cognitive neuroscience research has shown that certain brain regions are associated with specific cognitive abilities, such as language, naming, and decision-making. How and where these specific abilities are integrated in the brain to support complex cognition is still under investigation. However, researchers at the University of Iowa and Washington University in St. Louis, Missouri, believe that several hub regions may be especially important for the brain to function as an integrated network. In research published online Sept. 15 in the Early Edition of the Proceedings ...

Reproductive cell division has evolved a simple, mechanical solution to avoid chromosome sorting errors, researchers report in the Sept. 11 Science Express. This natural safeguard prevents incorrect chromosome counts and misalignments that lead to infertility, miscarriage, or congenital conditions. "Mistakes during reproductive cell division cause these problems, but what exactly goes wrong is often not understood," said Adele Marston of the Wellcome Trust Center for Cell Biology at the University of Edinburgh in Scotland and lead author of the study. Understanding ...

INDIANAPOLIS -- Adding a common epilepsy drug to a morphine regimen can result in better pain control with fewer side effects. Moreover, the combination can reduce the dosage of the opioid needed to be effective, according to a team of pain researchers at Indiana University. The result could bring significant relief to many patients with neuropathic pain, a difficult-to-treat condition often felt in the arms and legs and associated with nerve tissue damage. "There is a huge unmet need for better treatments for neuropathic pain," said Fletcher A. White, Ph.D., the Vergil ...

The quest to create artificial "squid skin" -- camouflaging metamaterials that can "see" colors and automatically blend into the background -- is one step closer to reality, thanks to a breakthrough color-display technology unveiled this week by Rice University's Laboratory for Nanophotonics (LANP). The new full-color display technology uses aluminum nanoparticles to create the vivid red, blue and green hues found in today's top-of-the-line LCD televisions and monitors. The technology is described in a new study that will be posted online this week in the Early Edition ...

New research has determined that a single group of microorganisms may be responsible for much of the world's vitamin B12 production in the oceans, with implications for the global carbon cycle and climate change. Although vitamin B12 is an essential molecule required by most life on this planet, it is only produced by a relatively small group of microorganisms because it is so large and complex. For humans, vitamin B12 plays a key role in maintaining the brain and nervous systems, as well as DNA synthesis in cells throughout the body. Professors Andew Doxey and Josh ...

Sugar is a vital source of energy for both plants and animals alike. Understanding just how sugar makes its way into the cell could lead to the design of better drugs for diabetes patients and an increase in the amount of fruits and vegetables farmers are able to grow. Stanford University researchers have recently uncovered one of these "pathways" into the cell by piecing together proteins slightly wider than the diameter of a strand of spider silk. To determine the size, shape and orientation of one of the newest (and smallest) of these proteins, the sugar transporter, ...

PITTSBURGH—Molecules containing carbon-halogen bonds are produced naturally across all kingdoms of life and constitute a large family of natural products with a broad range of biological activities. The presence of halogen substituents in many bioactive compounds has a profound influence on their molecular properties. One of the Holy Grails in chemical science has been to find the late-stage, site-specific incorporation of a halogen atom into a complex natural product by replacing an sp³ C-H bond (one of the most inert chemical bonds known in an organic compound) with ...

At 11 p.m. EDT on Sunday, September 14, Tropical Depression 16-E was officially a remnant low pressure area. NOAA's GOES-West satellite showed the clouds associated with the remnants being drawn into the massive circulation of nearby Hurricane Odile. At 5 a.m. on Sunday, September 14, Tropical Depression 16-E (TD 16-E) was still holding together despite being close to the circulation of Hurricane Odile. At that time, the center of tropical depression 16-E was located near latitude 14.9 north and longitude 115.3 west. That's about 655 miles (1,055 km) south-southwest ...

NASA's Aqua satellite observed Typhoon Kalmaegi crossing the South China Sea and a satellite image from the MODIS instrument aboard made it look like a whirlpool of clouds. On Sunday, September 14, Kalmaegi passed over northern Luzon, Philippines and emerged into the South China Sea. Typhoon Kalmaegi's maximum sustained winds were near 65 knots (75 mph) making it a category one hurricane on the Saffir-Simpson scale as it moved over the Philippines. On September 15 at 05:15 UTC (1:15 a.m. EDT) the Moderate Resolution Imaging Spectroradiometer aboard NASA's Aqua satellite ...

Toronto – Calculating the pros and cons of a potential decision is a way of decision-making. But repeated engagement with numbers-focused calculations, especially those involving money, can have unintended negative consequences, including social and moral transgressions, says new study co-authored by a professor at the University of Toronto's Rotman School of Management. Based on several experiments, researchers concluded that people in a "calculative mindset" as a result of number-crunching are more likely to analyze non-numerical problems mathematically and not take ...

Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations. It could also prevent the need for a painful, invasive test given to transplant patients at risk of rejecting their donor organs and replace it with a blood test that reveals traces of donor DNA. In a report in the September issue of The Journal of Molecular Diagnostics, the research team says laboratory tests already show that ...

URBANA, Ill. – Female college freshmen understand the benefits of eating healthy foods and know which foods they should include in their diets. But they lack confidence in their ability to act on that knowledge, especially when it comes to getting enough calcium, says a new University of Illinois study. "The women in our study weren't very confident about their ability to eat a healthful diet, especially if they had to do something physical like chop vegetables or go shopping. The motivation just wasn't strong if they were at a party or in places where there were other ...

Web-based training targeted at college-aged men is an effective tool for reducing the number of sexual assaults on U.S. campuses, according to a researcher in the School of Public Health at Georgia State University. The RealConsent program reduced sexually violent behavior and increased the likelihood a male student would intervene to prevent a sexual assault, said Dr. Laura Salazar, associate professor of health promotion and behavior, who published the findings in the paper, "A Web-Based Sexual Violence Bystander Intervention for Male College Students: Randomized Controlled ...

A published study indicates that lowland tapir populations may continue to drop in French Guiana, despite recent restrictions on hunting. Researchers from the Office National de la Chasse et de la Faune Sauvage in French Guiana and San Diego Zoo Global reviewed data retrieved from camera traps in the Nouragues National Reserve over the last four years and compared this data to current harvest rates in the region. "In 2011, restrictions were placed on hunting tapirs in French Guiana," said Matthias Tobler, a scientist with the San Diego Zoo Institute for Conservation Research. ...

EUGENE, Ore. -- Clinical psychologists are being urged by two University of Oregon researchers to recognize the experiences of institutional betrayal so they can better treat their patients and respond in ways that help avoid or repair damaged trust when it occurs in their own institutions. The call to action for clinicians as well as researchers appears in a paper in the September issue of the American Psychologist, the leading journal of the American Psychological Association. In their paper, UO doctoral student Carly P. Smith and psychology professor Jennifer J. ...

Johns Hopkins University political scientists wanted to know if America's unelected officials have enough in common with the people they govern to understand them. The answer: Not really. Surveying 850 people who either work in the federal government or directly with it, researchers found that the inside-the-Beltway crowd has very little in common with America at large. Washington insiders are more likely to be white. They are more educated. Their salaries are higher, they vote more often and they have more faith in the fairness of elections. They are probably Democrat ...

Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate view of Earth's first geologic eon, called the Hadean, has gained substantial new support from the first detailed comparison of zircon crystals that formed more than 4 billion years ago with those formed contemporaneously in Iceland, which has been proposed as a possible geological analog for early Earth. The study was conducted by a team of geologists directed by Calvin ...

For multicellular life—plants and animals—to thrive in the oceans, there must be enough dissolved oxygen in the water. In certain coastal areas, extreme oxygen-starvation produces "dead zones" that decimate marine fisheries and destroy food web structure. As dissolved oxygen levels decline, energy is increasingly diverted away from multicellular life into microbial community metabolism resulting in impacts on the ecology and biogeochemistry of the ocean. Over the past 50 years, oxygen minimum zones (OMZs) have expanded due to climate change and increased waste run-off ...

PORTLAND, Ore. – A recent guideline for using statins to reduce atherosclerotic cardiovascular disease has wavered too far from the simple cholesterol goals that have saved thousands of lives in the past decade, and doesn't adequately treat patients as individuals, experts said today in a national report. An expert panel coordinated by the National Lipid Association has created its own outline for how to best treat people at risk for cardiovascular disease, which they say focuses on reducing cholesterol to an appropriate level, and puts less emphasis on whether or not ...
