When renowned explorer Richard E. Byrd returned from the first-ever flight to the North Pole in 1926, he sparked a controversy that remains today: Did he actually reach the pole? By studying Byrd's navigation techniques, a researcher at The Ohio State University has determined that Byrd indeed neared the Pole, but likely only flew within 80 miles of it before turning back.
Restructuring work hours for first-year medical residents to accommodate a 2011 duty hour limit of no more than 16 shift hours substantially increases patient handovers, but doesn’t significantly affect efficiency and quality of care among medical inpatients, a Vanderbilt University Medical Center study has found.
A new study from Wake Forest Baptist Medical Center found that it is nearly impossible for patients to determine the true cause of their migraine episodes without undergoing formal experiments.
A team of researchers led by Associate Professor Maria Kozhevnikov from the Department of Psychology at the National University of Singapore (NUS) Faculty of Arts and Social Sciences showed, for the first time, that it is possible for core body temperature to be controlled by the brain. The scientists found that core body temperature increases can be achieved using certain meditation techniques (g-tummo) which could help in boosting immunity to fight infectious diseases or immunodeficiency.

Joint study by U-M Health System and RAND estimates total dementia care costs at $159- $200 billion a year, expected to nearly double with aging population
Why is it so hard for some people to resist the least little temptation, while others seem to possess incredible patience, passing up immediate gratification for a greater long-term good? The answer, suggests a new study from Washington University in St. Louis, is that patient people focus on future rewards in a way that makes the waiting process seem much more pleasurable.
A new study examines how American families cope with unexpected financial setbacks and how those periods of economic uncertainty draw down financial resources. The report studies families across race and income levels, revealing different experiences resulting from unemployment and the difficult choices many of them face.
By stimulating one part of the brain with laser light, researchers at the National Institutes of Health (NIH) and the Ernest Gallo Clinic and Research Center at UC San Francisco (UCSF) have shown that they can wipe away addictive behavior in rats – or conversely turn non-addicted rats into compulsive cocaine seekers.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Many navigators used this object to make their way across the oceans. A new composite image from three NASA telescopes -- Chandra, Hubble, and Spitzer -- shows this galaxy like Ferdinand Magellan, who lends his name to the SMC, could never have imagined.
A study in mice with genetic mutations seen in human Alzheimer's disease found that the feeling of hunger itself may protect against the disease.

A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease.
Risk prediction tools that estimate future risk of heart disease and stroke may be more useful predictors of future decline in cognitive abilities, or memory and thinking, than a dementia risk scores, according to a new study published in the April 2, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
The largest harmful algae bloom in Lake Erie's recorded history was likely caused by the confluence of changing farming practices and weather conditions that are expected to become more common in the future due to climate change.
Men with an inherited genetic condition called Lynch syndrome face a higher lifetime risk of developing prostate cancer and appear to develop the disease at an earlier age, according to a new study led by researchers at the University of Michigan Comprehensive Cancer Center.
Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
Surveillance is everywhere, from street corner cameras to the subject of books and movies. “We talk a lot about why surveillance is bad, but we don’t really know why,” says Neil Richards, JD, privacy law expert and professor of law at Washington University in St. Louis. “We only have a vague intuition about it, which is why courts don’t protect it. We know we don’t like it, and that it has something to do with privacy, but beyond that, the details can be fuzzy.” Richards’ new article on the topic, “The Danger of Surveillance,” will be published in the next issue of the Harvard Law Review.
Researchers have developed an ultra-compact passive true time delay device that could help reduce the size, complexity, power requirements and cost of phased array designs. The device uses the difference in speed between light and sound to create nanosecond signal delays.

Virginia Tech College of Engineering researchers have unveiled Cyro, a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds.
• The current number of cancer survivors is 13.7 million. • The increase is primarily due to aging of the population. • Survival is not uniform across cancer types.
Stars ten times as massive as the Sun, or more, should not exist: as they grow, they tend to push away the gas they feed on, starving their own growth. Scientists have been struggling to figure out how some stars overcome this hurdle. Now, a group of researchers led by two astronomers at the University of Toronto suggests that baby stars may grow to great mass if they happen to be born within a corral of older stars.
In the latest achievement in efforts to see what may lie underneath the surface of great works of art, scientists today described the first use of an imaging technology like that used in airport whole-body security scanners to detect the face of an ancient Roman man hidden below the surface of a wall painting in the Louvre Museum in Paris.
One of the Crescent City’s time-honored traditions – a steaming bowl of Yak-a-mein Soup, a.k.a., “Old Sober” — after a night of partying in the French Quarter actually does have a basis in scientific fact. That was the word today from an overview of the chemistry of hangovers, presented as part of the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
New evidence from Iowa State researchers demonstrates a link between video games and youth violence and delinquency. The research shows a strong connection even when controlling for a history of violence and psychopathic traits among juvenile offenders.
