Scientists at USC have uncovered evidence that even when hydrothermal sea vents go dormant and their blistering warmth turns to frigid cold, life goes on.
Or rather, it is replaced.
A team led by USC microbiologist Katrina Edwards found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are supplanted, once the vents go cold, by microbes that feed on the solid iron and sulfur that make up the vents themselves.
COLUMBUS, Ohio – On any given weekend, at least 10 percent of students at a single college could be hosting a party, and on average, party hosts who live off campus are drinking more and engaging in more alcohol-related problem behaviors than are the students attending their bashes, research suggests.
In contrast, hosts of parties held on campus tend to drink less than do the students attending their gatherings, according to the study.
RIVERSIDE, Calif. – In August 2010, an entomologist at the University of California, Riverside discovered a tiny fairyfly wasp in upstate New York that had never been seen in the United States until then. Nearly exactly a year later, he discovered the wasp in Irvine, Calif., strongly suggesting that the wasp is well established in the country.
Called Gonatocerus ater, the wasp is about 1 millimeter long and arrived in North America from Europe. It lays its eggs inside the eggs of leafhoppers.
ALBUQUERQUE, N.M. – Research by a team of Sandia National Laboratories chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste.
The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. "This is one of the first attempts to use a MOF for iodine capture," said chemist Tina Nenoff of Sandia's Surface and Interface Sciences Department.
– A pair of studies by The Children's Hospital of Philadelphia (CHOP) and State Farm® identify factors that may lead teens to drive with multiple peer passengers and, then, how those passengers may affect their driver's behavior just before a serious crash. The studies were published today in the Journal of Adolescent Health.
Researchers from North Carolina State University have developed a new method for creating elastic conductors made of carbon nanotubes, which will contribute to large-scale production of the material for use in a new generation of elastic electronic devices.
The skeletal structure of the foot and ankle differs significantly between human sprinters and non-sprinters, according to Penn State researchers. Their findings not only help explain why some people are faster runners than others, but also may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy.
EPFL scientist are among the leaders in the race to develop an industry-ready prototype of a 3D chip as well as a high-performance and reliable manufacturing method. The chip is composed of three or more processors that are stacked vertically and connected together—resulting in increased speed and multitasking, more memory and calculating power, better functionality and wireless connectivity.
Louisville, AZ—Working mothers may be busy, but they like it that way. A recent study of employed moms finds that most would work even if they didn't have to, but they're also looking for new ways to negotiate the demands of mothering and the pressures to be an "ideal" employee.
The Twenty-four Solar Terms are ancient Chinese terms used for about 2000 years. They describe 24 stages or timings associated with seasonal changes in phenology and agricultural activity throughout a year. Qian et al. from the Key Laboratory of Regional Climate-Environment for East Asia, Chinese Academy of Sciences, quantitatively defined the somewhat 'astronomic' term for the first time, based on modern temperature records. This facilitated an investigation of changes in the climatic Solar Terms under global warming over the past half-century.
Troy, N.Y. – Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn't even know it's there.
Engineering researchers at Rensselaer Polytechnic Institute and Rice University coated pieces of gold, copper, and silicon with a single layer of graphene, and then placed a drop of water on the coated surfaces. Surprisingly, the layer of graphene proved to have virtually no impact on the manner in which water spreads on the surfaces.
New University of Illinois sweet corn research shows that higher yield and profitability are possible with greater plant populations of certain hybrids.
Although it's a common practice to study plant populations in field corn, U of I associate professor of crop sciences and USDA-ARS ecologist Marty Williams, said almost no research exists for determining the number of plants needed to optimize yield in processing sweet corn, which accounts for most of the U.S. sweet corn acreage.
Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material! Using lasers, researchers cooled membrane fluctuations to minus 269 degrees C.
BUFFALO, N.Y. -- By tweaking the smallest of parts, a trio of University at Buffalo engineers is hoping to dramatically increase the amount of sunlight that solar cells convert into electricity.
With military colleagues, the UB researchers have shown that embedding charged quantum dots into photovoltaic cells can improve electrical output by enabling the cells to harvest infrared light, and by increasing the lifetime of photoelectrons.
A new study by researchers at the Johns Hopkins Center for Injury Research and Policy and the Centers for Disease Control and Prevention (CDC) documents a need for increased injury prevention efforts in many of the most popular activities for kids (walking, bicycling, swimming, sports and playground use) in the United States. Injury is the leading cause of death for young people in the U.S., yet many public health efforts to promote physical activity in kids do not consider the numerous available strategies to incorporate injury prevention.
