Researchers from North Carolina State University and University of North Carolina at Chapel Hill have developed a new technique that uses sound waves to rapidly separate selected collections of cells for use in biomedical research.

University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.
Children living with attention deficit hyperactivity disorder (ADHD) tend to feel that they benefit from medication to treat the condition and do not feel that the medication turns them into 'robots', according to a report published today. In fact, they report feeling that medication helps them to control their behaviour and make better decisions. The study, which gives a voice to the children themselves, provides valuable insights into their experiences and the stigma they face.
Exploring the evolutionary tree of life is now as easy as navigating an online map, thanks to a new interactive website called OneZoom, which went live today.
PITTSBURGH—Crude oil extraction could be improved significantly and accessible domestic oil reserves could be expanded with an economical CO2 thickener being developed by University of Pittsburgh engineers, thanks to a $1.3 million grant from the U.S. Department of Energy.
Volcanic eruptions vary from common, small eruptions that have little impact on humans and the environment to rare, large-to-gigantic eruptions so massive they can threaten civilizations.
Are there more tropical cyclones now than in the past? – or is it just something we believe because we now hear more about them through media coverage and are better able detect them with satellites? New research from the Niels Bohr Institute clearly shows that there is an increasing tendency for cyclones when the climate is warmer, as it has been in recent years. The results are published in the scientific journal PNAS.
PHILADELPHIA — The colors of a butterfly's wings are unusually bright and beautiful and are the result of an unusual trait; the way they reflect light is fundamentally different from how color works most of the time.
A team of researchers at the University of Pennsylvania has found a way to generate this kind of "structural color" that has the added benefit of another trait of butterfly wings: super-hydrophobicity, or the ability to strongly repel water.
PROVIDENCE, R.I. [Brown University] — Computer-delivered and face-to-face interventions both can help curb problematic college drinking for a little while, but only in-person encounters produce results that last beyond a few months, according to a new analysis of the techniques schools use to counsel students on alcohol consumption.
Ylva Sommerland, from the University of Gothenburg, Sweden, has studied the tomboy in manga, a girl manoeuvring in masculine situations. The study concerns sports manga and fantasy manga for teens – genres that offer plenty of tomboy stories.
The study focuses on a tomboy found in Mitsuru Adachi's sports manga Cross Game. Sports manga is immensely popular in Japan, and Mitsuru Adachi is one of the most well-known artists in this genre. He has been active since the 1970s.
Spintronic technology, in which data is processed on the basis of electron "spin" rather than charge, promises to revolutionize the computing industry with smaller, faster and more energy efficient data storage and processing. Materials drawing a lot of attention for spintronic applications are dilute magnetic semiconductors – normal semiconductors to which a small amount of magnetic atoms is added to make them ferromagnetic. Understanding the source of ferromagnetism in dilute magnetic semiconductors has been a major road-block impeding their further development and use in spintronics.
When we read a text, we hear a voice talking to us. Yet the voice changes over time. In his new book titled Poesins röster, Mats Malm, professor in comparative literature at the University of Gothenburg, Sweden, shows that when reading older literature, we may hear completely different voices than contemporary readers did – or not hear any voices at all.
CINCINNATI—A joint study by University of Cincinnati Department of Emergency Medicine and Cincinnati Children's Hospital Medical Center researchers has found that, in contrast to popular opinion, major holidays are associated with a lower number of suicide attempts by poisoning.
The study found that holidays like Christmas and Thanksgiving may actually be protective against suicide attempts, possibly due to the increased family or social support structures present around those times. In contrast, New Year's Day had significantly higher numbers of suicide attempts by overdose.
An experiment carried out on rodents exposed to fuel similar to that of the Prestige tanker oil spill – which took place nearly a decade ago – shows that inhalation of the fuel causes damage to genetic material. According to the study, led by the University of A Coruña, the results could be used in relation to people who carry out the industrial cleaning of coasts.
