Scientists have measured a significant and potentially pivotal difference between the brains of patients with an inherited form of Alzheimer’s disease and healthy family members who do not carry a mutation for the disease.
Stress felt by dad—whether as a preadolescent or adult—leaves a lasting impression on his sperm that gives sons and daughters a blunted reaction to stress, according to a new preclinical study in the Journal of Neuroscience by researchers at the University of Pennsylvania. The findings point to a never-before-seen epigenetic link to stress-related diseases such as anxiety and depression passed from father to child.
Using hands-free devices to talk, text or send e-mail while driving is distracting and risky, contrary to what many people believe, says a new University of Utah study issued June 12 by the AAA Foundation for Traffic Safety.
University of Washington researchers have demonstrated that when humans use brain-computer interfaces, the brain behaves much like it does when completing simple motor skills such as kicking a ball, typing or waving a hand. Learning to control a robotic arm or a prosthetic limb could become second nature for people who are paralyzed.
People who think they have perfect pitch may not be as in tune as they think, according to a new study in which people failed to notice a gradual change in pitch while listening to music. When tested afterward, people said notes that were in tune at the beginning sounded out of tune.

The study, which used advanced imaging techniques and cognitive tests that assessed memory, published online today in the journal Radiology.
New research sheds light on how the tropics came to be teeming with species while the poles harbor relatively few. Furthermore, it confirms that the tropics have been and continue to be the Earth’s engine of biodiversity.
The reason dark matter, which makes up 85 percent of all the matter in the universe, is invisible could be because it possesses a rare, donut-shaped type of electromagnetism instead of the more exotic forces that have been proposed, according to an analysis of a pair of Vanderbilt theoretic physicists.
Research from North Carolina State University, the Research Triangle Institute (RTI) and the University of South Florida shows that outpatient treatment of mental illness significantly reduces arrest rates for people with mental health problems and saves taxpayers money.
GAINESVILLE, Fla. --- Maybe better call that cab, after all: A new University of Florida study found that 35 percent of designated drivers had quaffed alcohol and most had blood-alcohol levels high enough to impair their driving.
If you think keeping up with what’s happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by 7 billion – and you’ll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system capable of analyzing billions of tweets and other social media messages in just seconds.
A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events.

Between 5 and 10 percent of those older than 70 are frail and at increased risk of death, debilitation and hospitalizations. The medical condition is treatable, writes a Saint Louis University physician in a consensus article from representatives of six international and national medical societies. Doctors need to screen everyone 70 and older for physical frailty.
U.S. paleontologists led by Jason Head of the University of Nebraska-Lincoln announced fossils of giant lizard Barbaturex morrisoni this week. Their analysis shows that it is one of the biggest known lizards ever to have lived on land. They've named the creature after Doors lead singer Jim Morrison.
Scientists, like Buddhist monks and Zen masters, have known for years that meditation can reduce anxiety, but not how. Researchers at Wake Forest Baptist Medical Center, however, have succeeded in identifying the brain functions involved.
A new study by researchers at Wake Forest University shows Bertholdia trigona, a species of tiger moth found in the Arizona desert, can tell if an echo-locating bat is going to attack it well before the predator swoops in for the kill – making the intuitive, tiny-winged insect a master of self-preservation.
Researchers at the University of Adelaide have found that a lake on an island off the coast of Queensland, Australia, has been relatively untouched by changes in climate for the past 7000 years, and has so far also resisted the impact of humans.
New research from McMaster University suggests women can remember faces better than men, in part because they spend more time studying features without even knowing it, and a technique researchers say can help improve anyone’s memories.
Another piece of the puzzle to better understand and treat obsessive compulsive disorder (OCD) has fallen into place with the publication of new research that shows that the structural brain abnormalities of Doberman pinschers afflicted with canine compulsive disorder (CCD) are similar to those of humans with OCD. The research suggests that further study of anxiety disorders in dogs may help find new therapies for OCD and similar conditions in humans.
Most apes eat leaves and fruits from trees and shrubs. New studies spearheaded by the University of Utah show that human ancestors expanded their menu 3.5 million years ago, adding tropical grasses and sedges to an ape-like diet and setting the stage for our modern diet of grains, grasses, and meat and dairy from grazing animals.
Smartphones and tablets can make for sleep-disrupting bedfellows. One cause is believed to be the bright light-emitting diodes that allow the use of mobile devices in dimly lit rooms; the light exposure can interfere with melatonin, a hormone that helps control the natural sleep-wake cycle. But there may be a way to check your mobile device in bed and still get a good night’s sleep. A Mayo Clinic study suggests dimming the smartphone or tablet brightness settings and holding the device at least 14 inches from your face while using it will reduce its potential to interfere with melatonin and impede sleep.
The fate of a species may rest upon a single butterfly captured in late May by University of Florida lepidopterists.
Our Solar System's Milky Way neighborhood just went upscale. We reside between two major spiral arms of our home galaxy, in a structure called the Local Arm. New research using the ultra-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) indicates that the Local Arm, previously thought to be only a small spur, instead is much more like the adjacent major arms, and is likely a significant branch of one of them.
A recent study of physical attractiveness and how it impacts real estate brokers’ pay and productivity shows that the more attractive the real estate agent, the higher the listing price of the home for sale.
Cancer immunotherapy is showing promise in treating patients with a variety of advanced, metastatic tumors, as evidenced by two newly unveiled studies from Yale Cancer Center.

The National Endowment for the Humanities (NEH) has awarded researchers at the University of California, Riverside a $60,000 grant to continue their development of face-recognition software to help identify unknown subjects of portrait art.
Climate is greatly influenced by the flow of heat energy carried by ocean currents. But precisely quantifying the mixing between the ocean and the atmosphere is hampered by a lack of detail in models of the ocean and of the water cycle. And in both models, knowing the salt content of the water is essential.
University of Arkansas researchers conducted a life-cycle analysis of fluid milk that will provide guidance for producers, processors and others throughout the dairy supply chain.
A Facebook profile is an ideal version of self, full of photos and posts curated for the eyes of family, friends and acquaintances. A new study shows that this version of self can provide beneficial psychological effects and influence behavior.
Researchers have found that a 260-million-year-old reptile is the earliest known version of the turtle. The discovery fills a large gap in the turtle fossil record and provide clues on how the turtle's unique shell evolved.
Whether damaged by injury, disease or age, your body can’t create new bone, but maybe science can. Researchers at North Dakota State University, Fargo, are making strides in tissue engineering, designing scaffolds that may lead to ways to regenerate bone. Published in the Journal of Biomedical Materials Research Part A, the research of Dr. Kalpana Katti, Dr. Dinesh Katti and graduate student Avinash Ambre includes a novel method that uses nanosized clays to make scaffolds to mineralize bone minerals such as hydroxyapatite.

UCLA researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy women, they found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function, both while in a resting state and in response to an emotion-recognition task.
People will lie about their sexual behavior to match cultural expectations about how men or women should act – even though they wouldn’t distort other gender-related behaviors, new research suggests.
A large analysis of more than 100 studies from around the world shows that exposure to pesticides, or bug and weed killers, and solvents is likely associated with a higher risk of developing Parkinson’s disease. The research appears in the May 28, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
In the heat of World War II, men who experienced intense combat were more than twice as likely to turn to prayer as those who did not, reports a Cornell University economist in the forthcoming June/July issue of Journal of Religion and Health. And the more that the veterans reported they disliked the war, the more religious they were 50 years after combat.
The Department of Energy's Oak Ridge National Laboratory has begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.
Sugar isn’t always sweet to German cockroaches. In a new NC State study published in Science, researchers show that glucose sets off bitter receptors in roach taste buds, causing roaches to avoid foods that bring on this taste-bud reaction.
Astronomers have resolved a major problem in their understanding of a class of stars that undergo regular outbursts by accurately measuring the distance to a famous example of the type.
Magnetars – the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation – are some of the most extreme objects known in the Universe. A major campaign using NASA's Chandra X-ray Observatory and several other satellites shows magnetars may be more diverse – and common – than previously thought.
