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.
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."
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals its surface gravity, one of the key properties that astronomers use to calculate a star’s physical properties and assess its evolutionary state.
A new study led by the Wildlife Conservation Society says that the American alligator and a dozen other crocodile species enjoy an occasional taste of fruit along with their normal meat-heavy diets of mammals, birds, and fish.
Glucagon, a hormone involved in regulating appetite, loses its ability to help obese people feel full after a meal, but it continues to suppress hunger pangs in people with type 1 diabetes, according to a recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
While observing a newborn star, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope discovered twin jets of matter blasting out into space at record-breaking speed. These surprisingly forceful molecular "winds" could help refine our understanding of how stars impact their cloudy nurseries and shape their emerging solar systems.
On August 20, JoVE, the Journal of Visualized Experiments will publish a technique accommodating two challenges inherent in brain-implantation technology: gauging the property changes that occur during implantation and measuring them on a micro-scale.
Children who have higher levels of Bisphenol A (BPA), a chemical previously used in many products for kids, like baby bottle and plastic toys, had a higher odds of obesity and adverse levels of body fat, according to a new study from University of Michigan researchers.
When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by NCAR shows that three atmospheric patterns drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably.
Virginia Tech researchers integrated a specific type of sensor into a typical construction helmet to allow continuous and noninvasive monitoring of construction workers’ blood gas saturation levels. The results of their study showed that a user of this helmet would be warned of impending carbon monoxide poisoning with a probability of greater than 99 percent, and won them a Best Paper award.

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.
When mice ate a diet of 25 percent extra sugar – the mouse equivalent of a healthy human diet plus three cans of soda daily – females died at twice the normal rate and males were a quarter less likely to hold territory and reproduce, according to a toxicity test developed at the University of Utah.
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.

It's been a long-held belief by many that singing in a foreign language can help you learn that language. A new study provides the first scientific evidence to affirm that claim. The finding is particularly relevant as internationalization increases and the importance and necessity of learning a second language grows.
Researchers at the Georgia Institute of Technology have “painted” the Mona Lisa on a substrate surface approximately 30 microns in width – or one-third the width of a human hair. The team’s creation, the “Mini Lisa,” demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.
The strikingly high prevalence of Type 2 diabetes in the American South can be partially traced to rapid economic growth between 1950 and 1980, new research suggests.
Brookhaven Lab scientists discover that critical temperature remains constant across interface superconductors regardless of changes in electron doping levels, challenging leading theories.
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.
