Why Alfred Hitchcock grabs your attention
2015-07-27
The movies of Alfred Hitchcock have made palms sweat and pulses race for more than 65 years. Georgia Institute of Technology researchers have now learned how the Master of Suspense affects audiences' brains. Their study measured brain activity while people watched clips from Hitchcock and other suspenseful films. During high suspense moments, the brain narrows what people see and focuses their attention on the story. During less suspenseful moments of the film clips, viewers devote more attention to their surroundings.
"Many people have a feeling that we get lost in ...
Sleep makes our memories more accessible, study shows
2015-07-27
Sleeping not only protects memories from being forgotten, it also makes them easier to access, according to new research from the University of Exeter and the Basque Centre for Cognition, Brain and Language. The findings suggest that after sleep we are more likely to recall facts which we could not remember while still awake.
In two situations where subjects forgot information over the course of 12 hours of wakefulness, a night's sleep was shown to promote access to memory traces that had initially been too weak to be retrieved.
The research, published today in the ...
New scoring system may help identify surgical patients at risk for pulmonary complications
2015-07-27
CHICAGO: Physicians at Thomas Jefferson University Hospital, Philadelphia, Penn., have developed an analytical tool to identify surgical patients at risk for costly respiratory complications. This tool may help hospitals avoid those complications and their related costs as Medicare and commercial payers exert increasing pressure on them by eliminating payment for patient complications that occur after operations and may extend hospital stays.
The investigators developed a scoring system to identify risk factors for ventilator dependence after major operations by using ...

2015-07-24
Lincoln, Neb., July 24th, 2015 --
If you've lived between the year 1560 and the present day, more power to you. Literally.
That's one of several conclusions reached by University of Nebraska-Lincoln ecologist John DeLong, who has co-authored the first study to quantify the relationship between human population growth and energy use on an international scale.
The study compiled several centuries' worth of data from Great Britain, the United States and Sweden to profile the dynamics between a skyrocketing population and its consumption of energy from fossil fuels and ...
Spines of boys and girls differ at birth
2015-07-24
Looking at measurements of the vertebrae - the series of small bones that make up the spinal column - in newborn children, investigators at Children's Hospital Los Angeles found that differences between the sexes are present at birth. Results of the study, now online in advance of publication in the August issue of the Journal of Pediatrics, suggest that this difference is evolutionary, allowing the female spine to adapt to the fetal load during pregnancy.
Using magnetic resonance imagining (MRI), the researchers found that vertebral cross-sectional dimensions, a key ...
Rice disease-resistance discovery closes the loop for scientific integrity
2015-07-24
When disease-resistant rice is invaded by disease-causing bacteria, a small protein produced by the bacteria betrays the invader. Upon recognizing that protein, the rice plants sense that a microbial attack is underway and are able to mount an immune response to fend off bacterial infection, reports a research team led by the University of California, Davis.
Identification of the tiny protein, called RaxX, holds promise for developing more disease-resistant crop varieties and therapeutic treatments for blocking microbial infections in both plants and animals, said the ...
TOPLESS plants provide clues to human molecular interactions
2015-07-24
Grand Rapids, Michigan (July 24, 2015)--Scientists at Van Andel Research Institute (VARI) have revealed an important molecular mechanism in plants that has significant similarities to certain signaling mechanisms in humans, which are closely linked to early embryonic development and to diseases such as cancer.
In plants as in animals and humans, intricate molecular networks regulate key biological functions, such as development and stress responses. The system can be likened to a massive switchboard--when the wrong switches are flipped, genes can be inappropriately turned ...
Seaworld's killer whales live as long as their wild counterparts
2015-07-24
ORLANDO, Fla. (July 21, 2015) - A new peer-reviewed study published in the Journal of Mammalogy by the Oxford University Press adds important insights to the debate over how long killer whales in human care live. The study found no difference in life expectancy between killer whales born at SeaWorld and a well-studied population of wild killer whales.
The study, "Comparisons of life-history parameters between free-ranging and captive killer whale (Orcinus orca) populations for application toward species management," compares current published data for survival and ...
Know it's a placebo? CU-Boulder study shows the 'medicine' could still work
2015-07-24
You don't think you're hungry, then a friend mentions how hungry he is or you smell some freshly baked pizza and whoaaa, you suddenly feel really hungry. Or, you've had surgery and need a bit of morphine for pain. As soon as you hit that button you feel relief even though the medicine hasn't even hit your bloodstream.
These are two examples of the oft-studied placebo effect that demonstrate the amazing and still somewhat confounding powers of the human brain.
Now, CU-Boulder graduate student Scott Schafer, who works in Associate Professor Tor Wager's Cognitive and Affective ...
Inbreeding not to blame for Colorado's bighorn sheep population decline
2015-07-24
The health of Colorado's bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has found that inbreeding--a common hypothesis for a recent decline--likely isn't to blame.
Bighorn herds tend to be small and isolated in their mountain ecosystems, putting the animals at high risk for a genetic "bottleneck," said Catherine Driscoll, a graduate student in the Department of Ecology and Evolutionary Biology at CU-Boulder and lead author of the study. Previous research ...
Prostate cancer not caused by shift work
2015-07-24
As well as the daily strain of their working lives, shift workers are probably also more likely than other people to develop cancer. While this has been well described for breast cancer, few studies had examined the correlation between shift work and prostate cancer. In a recent original article in Deutsches Ärzteblatt International (Dtsch Arztbl Int 112: 463-70), Gael P. Hammer et al. show that shift workers do not develop prostate cancer more frequently than their colleagues who work during the day.
Shift work is widespread: between approximately one in five and ...
Object recognition for robots
2015-07-24
CAMBRIDGE, Mass. -- John Leonard's group in the MIT Department of Mechanical Engineering specializes in SLAM, or simultaneous localization and mapping, the technique whereby mobile autonomous robots map their environments and determine their locations.
Last week, at the Robotics Science and Systems conference, members of Leonard's group presented a new paper demonstrating how SLAM can be used to improve object-recognition systems, which will be a vital component of future robots that have to manipulate the objects around them in arbitrary ways.
The system uses SLAM ...

Temple-led research analyzes impact of case volume on outcomes for DVT treatment
2015-07-24
(Philadelphia, PA) - Patients who have lower extremity proximal deep vein thrombosis (LE-DVT), or a blood clot in their leg, are increasingly undergoing minimally invasive catheter-based blood clot removal - also referred to as catheter-directed thrombolysis (CDT) - rather than solely being treated with traditional blood-thinning medications (anticoagulation alone). This trend is due to recent literature showing reductions in lifestyle-limiting post-thrombotic complications of acute DVT in patients who undergo CDT compared to those that are treated with anticoagulation ...

For prostate cancer patients, risk-specific therapies now more the norm
2015-07-24
After decades of overtreatment for low-risk prostate cancer and inadequate management of its more aggressive forms, patients are now more likely to receive medical care matched to level of risk, according to a study by researchers at UC San Francisco.
In the first study to document updated treatment trends, researchers found that from 2010 to 2013, 40 percent of men with low-risk prostate cancer opted for active surveillance, in which the disease is monitored closely with blood tests, imaging studies and biopsies. Treatment is deferred unless these tests show evidence ...
Astronomers discover Earth's bigger cousin
2015-07-24
Today an international team of astronomers from NASA's Kepler mission have announced the discovery of a near-Earth-sized planet in the habitable zone of a Sun-like star.
Dr Daniel Huber from the University of Sydney's School of Physics is part of the team which made the discovery with NASA's Kepler Space Telescope.
The planet named Kepler-452b is 60 per cent larger than Earth and orbits a Sun-like star with an orbital period of 385 days.
The mere 20 day difference between the planet's orbital period and that of Earth's makes it the closest analogue to Earth ever ...
