Existence of a new quasiparticle demonstrated
How do molecules rotate in a solvent? Answering this question is a complicated task since the rotation is perturbed by a large number of surrounding atoms, requiring large-scale computer simulations which are sometimes infeasible. Now, Mikhail Lemeshko from IST Austria has proven that angulons -- quasiparticles he proposed two years ago -- do in fact form when a molecule is immersed in superfluid helium. This offers a quick and simple description for rotation of molecules in solvents.

OU study clarifies risky decision making during a heart attack
In a recent study to determine why some individuals who experience symptoms for acute coronary syndrome decide to seek medical attention more quickly than others, a University of Oklahoma researcher has identified numeracy -- the ability to understand and apply numerical concepts as the primary decision delay risk factor for individuals experiencing the medical condition. Cardiovascular disease, which includes conditions such as acute coronary syndrome, is the number one killer worldwide responsible for about one in three deaths.

NSF CAREER award for bio-inspired research of burrowing animals
Dr. Junliang (Julian) Tao, assistant professor in civil engineering, has won a NSF CAREER Award. His work will promote the understanding of the highly efficient burrowing mechanisms of animals in the natural world. Burrowing organisms can inhabit a wide range of subsurface soil types, and adopt a variety of strategies facilitated by rhythmically changing their body shape. His findings will guide the design of next-generation, high-efficiency underground construction technologies and versatile small-scale underground robots.

Slower snowmelt in a warming world
As the world warms, mountain snowpack will not only melt earlier, it will also melt more slowly, according to a new study by scientists at the National Center for Atmospheric Research (NCAR).

A traffic cop for the cell surface: Researchers illuminate a basic biological process
A Colorado State University team of single-molecule biophysicists and biochemists have shed light on a long-obscured cellular process: a mammalian cell membrane's relationship with a scaffolding underneath it, the cortical actin cytoskeleton. For the first time, the CSU team has made real-time observations of this cytoskeleton acting as a barrier that organizes proteins on the cell's surface, effectively playing traffic cop on the cell's membrane activities.

Kids want parental help with online risk, but fear parental freak outs
In a study, teens rarely talked to their parents about potentially risky online experiences. Parents and children often have much different perceptions of and reactions to the same online situations. Some of these situations may include cyberbullying, sexual exchanges and viewing inappropriate content online.

Online security apps focus on parental control, not teen self-regulation
Mobile apps designed to keep teens safe online are overwhelmingly focused on parental control, which may be only a short-term solution that hinders a teen's ability to learn coping strategies in the long run. In a study of 74 Android mobile apps designed to promote adolescent online safety, the researchers said that 89 percent of security features on the apps are focused on parental control, while about 11 percent supported teen self-regulation.

Study reveals ways powerful 'master gene' regulates physical differences between sexes
A study by scientists at Indiana University has found that the master gene that regulates differences between males and females plays a complex role in matching the right physical trait to the right sex. The research, published Feb. 27 in the journal Nature Communications, reveals new details about the behavior of the gene called 'doublesex,' or dsx.

Triboelectric nanogenerators boost mass spectrometry performance
Triboelectric nanogenerators (TENG) convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, researchers have harnessed these devices to improve the charging of molecules in a way that dramatically boosts the sensitivity of a widely-used chemical analysis technique.

Super resolution imaging helps determine a stem cell's future
Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible. Understanding a stem cell's fate -- the type of cell it will eventually become -- and how far along it is in the process of development can help scientists better manipulate cells for stem cell therapy.

New pop-up strategy inspired by cuts, not folds
Origami-inspired materials use folds in materials to embed powerful functionality. However, all that folding can be pretty labor intensive. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are drawing material inspiration from another ancient Japanese paper craft -- kirigami.

Interactive health apps may inspire healthy behaviors, but watch the tone
Just like real doctors and nurses, online health tools with good -- but controlled -- communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more likely to follow the health behaviors suggested by the tool.

Colorado School of Mines and Virginia Tech to create minerals industry consortium
Colorado School of Mines is teaming with Virginia Tech to develop an integrated approach to locating, characterizing and visualizing mineral resources. The goal is to advance mining operations and boost exploration success rates while minimizing financial risk and environmental impact. The proposed Center for Advanced Subsurface Earth Resource Models would provide exploration and mining companies worldwide with new 3-D subsurface geological models, informing decision-making and risk management at all stages of the mining life cycle.

New polymer additive could revolutionize plastics recycling
Only 2 percent of the 78 million tons of manufactured plastics are currently recycled into similar products because polyethylene (PE) and polypropylene (PP), which account for two-thirds of the world's plastics, have different chemical structures and cannot be efficiently repurposed together. That could all change with a discovery by a Cornell University research team.

Bored by physical therapy? Focus on citizen science instead
Researchers have devised a method by which patients improved their repetitive rehabilitative exercises by contributing to scientific projects in which massive data collection and analysis is needed. The citizen science activity entailed the environmental mapping of a polluted body of water with a miniature instrumented boat, which was remotely controlled through physical gestures tracked by the Microsoft Kinect, a low-cost motion capture system.
