Scientific plagiarism: A growing problem in an era of shrinking research funding
As scientific researchers become evermore competitive for scarce funding, scientific journals are increasing efforts to identify submissions that plagiarize the work of others. Still, it may take years to identify and retract the plagiarized papers and give credit to the actual researchers. -

20:24Human stem cells capable of giving rise to any fetal or adult cell type are known as pluripotent stem cells. It is hoped that such cells, the most well known being human embryonic stem cells (hESCs), can be used to generate cell populations with therapeutic utility. In this context, neural derivatives of hESCs are being tested in clinical trials. However, Natalie Lefort and colleagues, at the Institute for Stem cell Therapy and Exploration of Monogenic diseases, France, have now generated cautionary data that suggest that additional quality controls need to be put in place to ensure that neural derivatives of human pluripotent stem cells are not genomically unstable, a common characteristic of cancer cells.

Brown fat burns calories in adult humans
Brown fat burns calories to generate body heat in rodents and newborn humans. Recently, adult humans have also been found to possess brown fat, leading to the suggestion that increasing the amount of brown fat a person has will make them slimmer. However, it has never been shown definitively that adult human brown fat burns energy. But now, researchers in Canada have provided this evidence.

20:03Researchers have found a genetic variation predisposing children to six-times greater risk of developing metabolic syndrome when taking second-generation anti-psychotic medications. Metabolic syndrome is a cluster of conditions that are risk factors for cardiovascular disease. The study showed a close association with two conditions in particular: high blood pressure and elevated fasting blood sugar levels, which is a precursor to diabetes.

20:03Evidence of cardiovascular disease and diabetes risk is present in the blood of adolescents who consume a lot of fructose, a scenario that worsens in the face of excess belly fat, researchers report.

20:03The many factors that contribute to how cells communicate and function at the most basic level are still not fully understood, but researchers have uncovered a mechanism that helps explain how intracellular membranes fuse, and in the process, created a new physiological membrane fusion model.

20:03Research by chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. They have used metal-organic frameworks to capture and remove volatile radioactive gas from spent nuclear fuel.

20:03In August 2010, an entomologist at the University of California, Riverside discovered a tiny fairyfly wasp in upstate New York that had never been seen in the United States until then. Nearly exactly a year later, he discovered the wasp in Irvine, Calif., strongly suggesting that the wasp is well established in the country. Called Gonatocerus ater, the 1-millimeter-long wasp was accidentally introduced in North America. It lays its eggs inside the eggs of leafhoppers.

New tools remind young internet users to protect privacy
Privacy Commissioner Jennifer Stoddart unveiled three new tools Tuesday to help young internet users protect their privacy online.

19:44They're small, creepy and suck your blood. Every parent dreads it, but it's inevitable -- the "lice letter." Though a lice infestation is about as common as a cold, trying to rid your life of them can be as much of a head-scratcher as those disgusting bugs themselves. A pediatrician now gives tips for dealing with lice.

19:44Every year between 3 and 10 percent of school-age children in this country are diagnosed with attention deficit hyperactivity disorder (ADHD). Increasingly, families are using natural or complementary therapies to improve their child’s attention or behavior, and often seek advice from an integrative pediatrician, according to a new study.

Is there still a chance of seeing the northern lights in Britain?
It could be possible to see the aurora borealis as far south as London. So how do you maximise your chances of seeing the spectacular light show?
The clue, of course, is in the name. Usually, to see the northern lights, or the aurora borealis as they are formally known, you would have to head towards the Arctic, but this week – with a bit of luck and the right conditions – it could be possible to see them as far south as London.
What should you do to maximise your chances? The first thing we need to see the northern lights is a clear night. "The aurora is above cloud levels, which means clear skies are necessary," says Sarah Reay, a geomagnetism scientist with the British Geological Survey.
According to Alison Richards, a spokesperson for the Met Office, "the cloud and rain will clear away on Wednesday evening after which we are expecting broken cloud overnight for the rest of the week."
Reay says the best places to see the aurora borealis are still "Scotland and northern England, going on experience from Sunday.
"Ideally, go somewhere dark, away from street lights. Look to the north because it is usually seen in the north, although this depends on where you are in the UK and as [geomagnetic] activity increases, it moves southwards. So it could appear anywhere. We usually recommend you look out for it around midnight, so from 10pm to 2am would be the best chance, but on Sunday, I think the peak activity was from 8pm to 11pm."
There is still a lot of doubt about how much we will be able to see, says Reay. "It's dependent on magnetic activity, which is highly variable. Sorry to be so vague, but it's difficult to tell how intense the storm will be until it actually arrives."
So wrap up warm and prepare for overwhelming awe – or bitter disappointment.

19:15SPACE.com - A wave of charged particles from an intense solar storm is pummeling the Earth right now, which may trigger stunning aurora displays and cause minor disruptions to satellites over the next two days, NASA scientists say.
