Researchers at the University of Illinois at Urbana-Champaign have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. "This method is a first-of-its-kind tool for manipulation and trapping of small nanoparticles in solution," explained Charles M. Schroeder, an assistant professor in the Department of Chemical and Biomolecular Engineering at Illinois. "Using fluid flow in a microfluidic device means that electrical, magnetic, optical, ...

Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this world. Lawrence Livermore scientist Nir Goldman and University of Ontario Institute of Technology colleague Isaac Tamblyn (a former LLNL postdoc) found that icy comets that crashed into Earth millions of years ago could have produced life building organic compounds, including the building blocks of proteins and nucleobases pairs of DNA and RNA. Comets contain a variety of simple molecules, such as water, ammonia, methanol ...

A recent article in the New England Journal of Medicine describes genetic testing of a rare blood cancer called atypical chronic neutrophilic leukemia (CNL) that revealed a new mutation present in most patients with the disease. The mutation also serves as an Achilles heel, allowing doctors at the University of Colorado Cancer Center to prescribe a never-before-used, targeted treatment. The first patient treated describes his best snowboarding season ever. "I'm a crazy sports fan," says the patient. "I go 30 days a season. I may be the oldest guy snowboarding on the mountain, ...

Physicists at the U.S. Department of Energy's Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings, reported in Nature Communications, offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors. "We found that the directions of smallest and largest resistivity within the conducting layers are significantly dependent on the composition of the compounds, and in some compositions, they change sign, or, in other words, electric current flows easier ...

WHAT: Untreated HIV infection destroys a person's immune system by killing infection-fighting cells, but precisely when and how HIV wreaks this destruction has been a mystery until now. New research by scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, reveals how HIV triggers a signal telling an infected immune cell to die. This finding has implications for preserving the immune systems of HIV-infected individuals. HIV replicates inside infection-fighting human immune cells called CD4+ T cells through ...

MOSS LANDING, CA — Surprisingly large amounts of discarded trash end up in the ocean. Plastic bags, aluminum cans, and fishing debris not only clutter our beaches, but accumulate in open-ocean areas such as the "Great Pacific Garbage Patch." Now, a paper by researchers at the Monterey Bay Aquarium Research Institute (MBARI) shows that trash is also accumulating in the deep sea, particularly in Monterey Canyon. Kyra Schlining, lead author on this study, said, "We were inspired by a fisheries study off Southern California that looked at seafloor trash down to 365 meters. ...

WASHINGTON -- A new report from the Institute of Medicine and National Research Council proposes priorities for a research agenda to improve understanding of the public health aspects of gun-related violence, including its causes, health burden, and possible interventions. The committee that wrote the report said significant progress can be achieved in three to five years through a research program that addresses five high-priority areas: the characteristics of gun violence, risk and protective factors, prevention and other interventions, gun safety technology, and the ...

The researchers have been tracking the evolution of Drosophila subobscura, a small fly that is very common all over Europe, since 1976. They are focusing on a specific type of genomic variability known as chromosomal inversion polymorphism. The study has compared how the flies' genomes change from spring to summer, summer to autumn and autumn to spring, over the years. In pre-2011 studies of one of D. subobscura's five chromosome pairs, performed in a population near the town of Santiago de Compostela, the researchers observed that this type of adaptation is related to ...

(SACRAMENTO, Calif.) — Offering flu vaccines at elementary schools could expand vaccination rates and reduce costs, according to a new study reported in the scientific journal Vaccine by researchers from UC Davis Health System; the Monroe County, New York, Department of Public Health; University of Rochester Medical Center; and U.S. Centers for Disease Control and Prevention (CDC). The best protection against flu for children at least 6 months of age is the seasonal vaccine, yet inoculation rates among children are low, according to the CDC. Only about 40 percent of ...

(SACRAMENTO, Calif.) —To attract and maintain a diverse, qualified academic workforce, institutions of higher education should have — and promote — policies to help balance career and family life, according to an article published by UC Davis researchers in the June 2013 issue of Academic Medicine. Policies allowing medical school faculty to care for family while advancing their careers are more available today than ever before, the authors said in the article. Yet these policies are also underused, primarily because faculty members do not know they exist. Based on ...

Scientists at the Department of Energy's Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies that power today's electronics. The ORNL battery design, which uses abundant low-cost elemental sulfur, also addresses flammability concerns experienced by other chemistries. "Our approach is a complete change from the current battery concept of two electrodes joined by a liquid electrolyte, which has been used over the last 150 to 200 years," said ...

WASHINGTON -- The U.S. Bureau of Land Management's (BLM) current practice of removing free-ranging horses from public lands promotes a high population growth rate, and maintaining them in long-term holding facilities is both economically unsustainable and incongruent with public expectations, says a new report by the National Research Council. The report says that tools already exist for BLM to better manage horses and burros on healthy ecosystems, enhance public engagement and confidence, and make the program more financially sustainable. It also provides evidence-based ...

URBANA, Ill. – Phosphorus is a vital nutrient for pig growth, but the majority of the phosphorus in common plant-based feedstuffs is bound to phytate and therefore is unavailable to pigs. Diets fed to pigs can be supplemented with microbial phytase to improve phosphorus digestibility, according to Hans S. Stein, a University of Illinois professor in animal sciences. Stein and his team at the U of I have recently published results indicating that a new microbial phytase derived from the bacterium Aspergillus oryzae is highly effective at releasing phosphorus from the ...

CHAMPAIGN, Ill. — Researchers report that a single, 20-minute session of Hatha yoga significantly improved participants' speed and accuracy on tests of working memory and inhibitory control, two measures of brain function associated with the ability to maintain focus and take in, retain and use new information. Participants performed significantly better immediately after the yoga practice than after moderate to vigorous aerobic exercise for the same amount of time. The 30 study subjects were young, female, undergraduate students. The new findings appear in the Journal ...

SAN FRANCISCO, June 5, 2013 -- As Father's Day draws near, psychologist Jeff Cookston says dads should ask their children for a little more feedback than they might get with the yearly greeting card. Just being a good parent may not be good enough, said Cookston, professor of psychology at San Francisco State University, who has studied fatherhood extensively. "There's a need for fathers to sometimes say to their kids, 'How am I doing? Am I the dad you need me to be?'" "Kids are actively trying to make sense of the parenting they receive," he explained, "and the meaning ...

WEST LAFAYETTE, Ind. - Researchers have demonstrated a method for "temporal cloaking" of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications. "More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the existing telecommunications infrastructure," said Purdue University graduate student Joseph Lukens, working with Andrew Weiner, the Scifres Family Distinguished Professor of Electrical and Computer Engineering. Other ...

WINSTON-SALEM, N.C. – June 5, 2013 – Cancer survivors who live in rural areas aren't as healthy as their urban counterparts, according to new research from Wake Forest Baptist Medical Center. Kathryn E. Weaver, Ph.D., assistant professor of social sciences and health policy at Wake Forest Baptist, said that this study, which builds on previous research showing that rural cancer survivors suffer worse health after cancer, looks at the role of health behaviors, such as smoking and physical inactivity. "It is concerning that we found higher rates of health-compromising ...

Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Want to change the song playing on your music system in the other room? Move your hand to the right and flip through the songs. University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality. Researchers have shown it's possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras. By using ...

MRI may be an effective way to diagnose mental illnesses such as bipolar disorder, according to experts from the Icahn School of Medicine at Mount Sinai. In a landmark study using advanced techniques, the researchers were able to correctly distinguish bipolar patients from healthy individuals based on their brain scans alone. The data are published in the journal Psychological Medicine. Currently, most mental illnesses are diagnosed based on symptoms only, creating an urgent need for new approaches to diagnosis. In bipolar disorder, there may be a significant delay in ...

PORTLAND, Ore. — The surgeon who more than two decades ago pioneered deep brain stimulation surgery in the United States to treat people with Parkinson's disease and other movement disorders has now developed a new way to perform the surgery — which allows for more accurate placement of the brain electrodes and likely is safer for patients. The success and safety of the new surgical technique could have broad implications for deep brain stimulation, or DBS, surgery into the future, as it may increasingly be used to help with a wide range of medical issues beyond Parkinson's ...

NASA's Aqua satellite passed over low pressure System 91L in the Gulf of Mexico and captured infrared imagery that revealed a lot of uplift and strong thunderstorms in the eastern part of the storm despite a poorly organized circulation. NOAA's GOES-East satellite showed the large extent of the low pressure area stretching from Mexico's Yucatan Peninsula to Florida. System 91L is a tropical low pressure area that has been lingering in the northwestern Caribbean Sea and the Gulf of Mexico for several days. The low pressure area is located in the central Gulf of Mexico ...

By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe. Using data from NASA's Chandra X-ray Observatory and NASA's Spitzer Space Telescope, which observes in the infrared, researchers have concluded one of every five sources contributing to the infrared signal is a black hole. "Our results indicate black holes are responsible for at least 20 percent of the cosmic infrared background, which ...

A NASA team delivered in May a sophisticated microwave radiometer specifically designed to overcome the pitfalls that have plagued similar Earth-observing instruments in the past. Literally years in the making, the new radiometer, which is designed to measure the intensity of electromagnetic radiation, specifically microwaves, is equipped with one of the most sophisticated signal-processing systems ever developed for an Earth science satellite mission. Its developers at NASA's Goddard Space Flight Center in Greenbelt, Md., shipped the instrument to NASA's Jet Propulsion ...

Research from the University of Alberta shows CFL players are more likely to value medical tests after concussions compared to university-level players. But the professional athletes were more apt to incorrectly believe it's OK to return to the sport within 24 to 48 hours if they had no symptoms. The study looked at how CFL athletes fared against their university-level peers when it came to concussion knowledge, and whether a one-hour concussion education program improved the two groups' knowledge. All of the CFL players realized the importance of seeking medical tests ...

Cincinnati, OH, June 6, 2013 -- Sports-related concussion has been referred to as an "epidemic" by the Centers for Disease Control and Prevention. Emergency department visits for concussions have increased 62% between 2001 and 2009. Despite the lack of data regarding the rates of concussions in youth football (children aged 8-12 years), concerns have been raised about the sport being dangerous for this age group. In a new study scheduled for publication in The Journal of Pediatrics, researchers analyzed the incidence rates of concussion in youth football players in this ...
