Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a University of Wisconsin–Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.
A new study, “Reassessment of Pre-Industrial Fire Emissions Strongly Affects Anthropogenic Aerosol Forcing,” by a Cornell University postdoctoral researcher, published in August in Nature Communications, finds that emissions from fire activity were significantly greater in the preindustrial era, which began around 1750, than previously thought. As a result, scientists have underestimated the cooling effect the aerosol particles produced by these fires had on the past climate.
Congenital muscular torticollis (CMT) is a common postural deformity in infants, and one that can be effectively treated by physical therapy. A set of updated, evidence-based recommendations for physical therapy management of CMT is presented in the October issue of Pediatric Physical Therapy. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Analyzing data from more than 400,000 people, researchers at Washington University School of Medicine in St. Louis have found that consuming one to two drinks four or more times per week — an amount deemed healthy by current guidelines — increases the risk of premature death by 20 percent.
Both the National Institute of Alcohol Abuse and Alcoholism and the Centers for Disease Control have concluded that up to one drink daily for women, and up to two drinks daily for men, fall within U.S. dietary guidelines. Several studies have reported that consuming one to two drinks on occasion – called low-level drinking – is protective against cardiovascular disease. However, other research has shown that any alcohol use appears to increase the risk of some types of cancer. This study used large-scale databases to analyze the association between alcohol use and risk of death.
When voters go to the polls, they aren't just voting for the candidate who best represents their views--they're also voting strategically to shape the balance of power between parties in the legislature.
Observation could help scientists find the universal key ingredient in the recipe for high-temperature superconductivity.
Treatment outcomes of psychological therapies and CBT in particular have not changed over several decades.
Computers in the future could be more energy-efficient, thanks to new research from Binghamton University, State University at New York.
Elementary-school students who participated in a comprehensive support intervention in the Boston public school district had about half the odds of dropping out of high school as students not in the intervention, according to a new study published online today in AERA Open, a peer-reviewed journal published by the American Educational Research Association.
Crop breeders are developing a biofortified wheat that could make proper nutrition easier.
Researchers from NYU School of Medicine, along with a national group of researchers, clinicians, policymakers, payers, patients, caregivers and healthcare system representatives designed and piloted Patient Priorities Care (PPC).
Columbia Engineers have created the first flat lens capable of correctly focusing a large range of colors of any polarization to the same focal spot without the need for any additional elements. Only a micron thick, their revolutionary "flat" lens is much thinner than a sheet of paper and offers performance comparable to top-of-the-line compound lens systems. UPenn nanophotonics expert Nader Engheta, who was not involved with this study, notes: "This…is an exciting development in the field of flat optics.”
Sea lettuce, a fast-growing seaweed that spawns massive “green tides,” is a prolific thief, according to research that for the first time sequenced the genome of a green seaweed
Leaf fossils discovered high in Australia’s Snowy Mountains have revealed a past history of warmer rainforest vegetation and a lack of snow, in contrast with the alpine vegetation and winter snow-covered slopes of today.
A study led by researchers at CHU Sainte-Justine in Montreal confirms that cannabis use is related to impaired and lasting effects on adolescent cognitive development.
a team of researchers has used an X-ray laser to measure, for the first time, how a plasma created by a laser blast expands in the hundreds of femtoseconds (quadrillionths of a second) after it’s created. Their technique could eventually reveal tiny instabilities in the plasma that swirl like cream in a cup of coffee.
Los investigadores de Mayo Clinic crearon un recurso genético para pronóstico del síndrome mielodisplásico (SMD). Los resultados se publican en la edición impresa correspondiente al mes de octubre de Mayo Clinic Proceedings.
A technique using umbilical cord blood stem cells could be a promising new approach for repair of cleft palate in infants, reports a paper in The Journal of Craniofacial Surgery, published in the Lippincott portfolio by Wolters Kluwer.
Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions.
