Scientists at Washington University School of Medicine in St. Louis have found a way that corrupted, disease-causing proteins spread in the brain, potentially contributing to Alzheimer’s disease, Parkinson’s disease and other brain-damaging disorders.
Astronomers have assembled, from more than 13 years of observations from NASA's Hubble Space Telescope, a series of time-lapse movies showing a jet of superheated gas — 5,000 light-years long — as it is ejected from a supermassive black hole in the giant elliptical galaxy M87.
Researchers found a preliminary link between workaholics and reduced physical and mental well-being.
New research from the Monell Center reveals that bubbles are not necessary to experience the unique ‘bite’ of carbonated beverages, which actually comes from carbonic acid. Bubbles do, however, enhance carbonation’s bite through the light physical feel of the bubbles picked up by our sense of touch.
The international Daya Bay Collaboration has announced new results about the transformations of neutrinos - elusive, ghostlike particles that carry invaluable clues about the makeup of the early universe. The latest findings include the collaboration's first data on how neutrino oscillation varies with neutrino energy, allowing the measurement of a key difference in neutrino masses known as "mass splitting."

An international team of astronomers led by BoMee Lee has established that mature-looking galaxies existed much earlier than previously known, about 11.5 billion years ago. “Finding them this far back in time is a significant discovery,” says lead author Lee. Reported in The Astrophysical Journal.
Newly released research findings from University of Utah neuroscientists assert that there is no evidence within brain imaging that indicates some people are right-brained or left-brained. For years in popular culture, the terms left-brained and right-brained have come to refer to personality types, with an assumption that some people use the right side of their brain more, while some use the left side more. Following a two-year study, University of Utah researchers have debunked that myth through identifying specific networks in the left and right brain that process lateralized functions.
A Sandia National Laboratories team completed acceptance testing on an enormous mobile scanner that makes smuggling radiological materials more difficult, the eighth such unit that Sandia has deployed worldwide.
Observations with NASA’s Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232.
New research from an ice core taken from West Antarctica shows that the warming that ended the last ice age in Antarctica began at least two, and perhaps four, millennia earlier than previously thought.

The study, published in the August issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), found there is an increased risk of ADHD in boys that have a history of allergy or asthma. The study also found an even stronger risk associated with milk intolerance.”
The decline and disappearance of stable, unionized full-time jobs with health insurance and pensions for people who lack a college degree has had profound effects on working-class Americans who now are less likely to get married, stay married and have their children within marriage than those with college degrees, a new University of Virginia and Harvard University study has found.
School lunch consumption and two hours or more of daily TV viewing are linked with obesity for middle school children, but a new study in Pediatrics also reveals gender differences in the habits leading to weight gain for girls and boys.
Pregnant women whose labors are induced or augmented may have an increased risk of bearing children with autism, especially if the baby is male, according to a large, retrospective analysis by researchers at Duke Medicine and the University of Michigan.
About 20 percent of cardiac arrest survivors report having a near death experience with visions and perceptions, but are the experiences real? A University of Michigan study suggests the dying brain is capable of well-organized electrical activity during the early stages of clinical death. The study in PNAS provides the first scientific framework for the near-death experience.
An anonymous stranger you encounter on websites like Yelp or Amazon may seem to be just like you, and a potential friend. But a stranger on a site like eBay is a whole different story.
A team of neuroscientists has identified a modification to a protein in laboratory mice linked to conditions associated with Alzheimer’s Disease. Their findings also point to a potential therapeutic intervention for alleviating memory-related disorders.

Brookhaven Lab scientists discover that critical temperature remains constant across interface superconductors regardless of changes in electron doping levels, challenging leading theories.
A new study by Berkeley-Haas Associate Professor Don Moore finds employment managers tend to ignore the context of past performance.
The digestive tract is home to a vast colony of bacteria, as well as the myriad viruses that prey upon them. Because the bacteria species vary from person to person, so does this viral population, the virome. By closely analyzing the virome of one individual over two-and-a-half years, researchers have uncovered new insights on the virome can change and evolve – and why the virome of one person can vary so greatly from that of another.
