Researchers have used an electrical current to orchestrate the flow of a group of cells, an achievement that could establish the basis for more controlled forms of tissue engineering and for potential applications such as "smart bandages" that use electrical stimulation to help heal wounds.

In the experiments, the researchers used single layers of epithelial cells, the type of cells that bind together to form robust sheathes in skin, kidneys, cornea and other organs. They found that by applying an electric current of about five volts per centimeter, they could encourage cells to migrate along the direct current field. 

Kids know it is wrong to steal stuff - they also seem to know it's wrong to steal an idea. They just discover it a little later.

University of Washington psychologist Kristina Olson and colleagues discovered that preschoolers often don't view a copycat negatively but by the age of 5 or 6, they do. It holds true even across cultures that typically view intellectual property rights in different ways, like in Germany where they violate international trademarks and hold a Science 2.0 conference and, worse, charge people to attend.

Researchers at the University of California, San Diego School of Medicine have identified a mechanism that explains why people with the hepatitis C virus get liver disease and why the virus is able to persist in the body for so long.

The hard-to-kill pathogen, which infects an estimated 200 million people worldwide, attacks the liver cells' energy centers – the mitochondria – dismantling the cell's innate ability to fight infection. It does this by altering cells mitochondrial dynamics.

The study, published in today's issue of the Proceedings of the National Academy of Sciences, suggests that mitochondrial operations could be a therapeutic target against hepatitis C, the leading cause of liver transplants and a major cause of liver cancer in the U.S.

A research team led by Paolo Macchiarini, MD, PhD at Karolinska Institutet in Sweden has successfully transplanted a regenerated esophagus into a rat using a bioreactor developed by Harvard Apparatus Regenerative Technology (HART), a spin-off of Harvard Bioscience. Macchiarini has previously done several successful regenerated trachea transplants in human patients using a HART bioreactor.

Until university leaders can supply politicians with better approaches to accountability, they're just going to count. In Norway right now, we're in the midst of counting season. And because of the sharp folks at Current Research Information System in Norway, we have detailed numbers. (Disclosure: I'm the head of the board at CRIStin.)

Along with counting, comes comparison. So, here's a little teaser from the high north and, sure, I'd like to know how it stacks up against your university.

In 2013, the 18,709 academic staff members at Norwegian colleges and universities were (co)authors on a total of 17,493 research articles, for an average of just less than one (co)authorship per academic employee.

The 15% fall in dietary salt intake, which is implicated in increased blood pressure, over the past decade in England is likely to have had a key role in the 40% drop in deaths from heart disease and stroke over the same period, according to a paper in BMJ Open.

Average salt intake across the nation is still far too high, the authors warn, and much greater effort is needed to curb the salt content of the foods we eat. 

The authors base their findings on an analysis of data from more than 31,500 people taking part in the Health Survey for England for the years 2003—when initiatives to curb population salt intake began across the UK—2006, 2008, and 2011.

 A meta-analysis that included 14 randomized controlled trials with a total of 626 adult participants found that  whey protein, either as a supplement combined with resistance exercise or as part of a weight-loss or weight-maintenance diet, may provide men and women benefits related to body composition.

A small icy object within the rings of Saturn may be a new moon, according to interpretation of images taken with Cassini's narrow angle camera on April 15, 2013 which show disturbances at the very edge of Saturn's A ring -- the outermost of the planet's large, bright rings.

One of these disturbances is an arc about 20 percent brighter than its surroundings, 750 miles (1,200 kilometers) long and 6 miles (10 kilometers) wide. Scientists also found unusual protuberances in the usually smooth profile at the ring's edge. Scientists believe the arc and protuberances are caused by the gravitational effects of a nearby object. 

PULLMAN, Wash. - Happy is as happy does, apparently—for human beings all over the world. Not only does acting extroverted lead to more positive feelings across several cultures, but people also report more upbeat behavior when they feel free to be themselves.

These findings were among those recently published in the Journal of Research in Personality in a paper by Timothy Church, professor of counseling psychology and associate dean of research in the College of Education at Washington State University. The research was funded by the National Science Foundation.

University of Adelaide research into parasites of cuttlefish, squid and octopus has uncovered details of the parasites' astonishing life cycles, and shown how they may help in investigating populations of their hosts.

Researcher Dr Sarah Catalano has described 10 new parasite species− dicyemid mesozoans −, which live in the kidneys of cephalopods (cuttlefish, squid and octopus). They are the very first dicyemid species to be described from Australian waters.
