Scientists from the University of New Hampshire and colleagues answer the question of why NASA’s Voyager 1, when it became the first probe to enter interstellar space in mid-2012, observed a magnetic field that was inconsistent with that derived from other spacecraft observations, in a study published today in the Astrophysical Journal Letters.
Researchers have developed a brain imaging technique for patients whose epilepsy does not respond to drug treatment and are not candidates for seizure-relieving surgeries. The imaging technique, known as glutamate chemical exchange saturation transfer (GluCEST), images changes in glutamate levels in brain structures that identify the location of seizures not detected with conventional MRI.
Winds of over 2km per second have been discovered flowing around planet outside of the Earth’s solar system, new research has found. The University of Warwick discovery is the first time that a weather system on a planet outside of Earth’s solar system has been directly measured and mapped.
A glacier in northeast Greenland that holds enough water to raise global sea levels by more than 18 inches has come unmoored from a stabilizing sill and is crumbling into the North Atlantic Ocean. Losing mass at a rate of 5 billion tons per year, glacier Zachariae Isstrom entered a phase of accelerated retreat in 2012, according to findings published in the current issue of Science.
>Wild-caught chimpanzees, who were orphaned and imported from Africa in their early infancy, exhibit an impaired social behaviour also as adults. So far long-term effects of early traumatic experiences on social behaviour were known only for humans and socially isolated chimpanzees.
The long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars.
In an eight-hour operation on an adult patient, Dr. Daniel Borsuk carried out facial reconstruction using virtual surgery and 3D models, removing a vascularized piece of pelvic bone and reshaping it to adapt it to the rest of the face before transplanting it through the inside of the mouth, with no scars left at all.
The sensitivity of marine communities to ocean warming rather than rising ocean temperatures will have strong short-term impacts on biodiversity changes associated with global warming, according to new research.
The sight of an asteroid being ripped apart by a dead star and forming a glowing debris ring has been captured in an image for the first time. Comprised of dust particles and debris, the rings are formed by the star’s gravity tearing apart asteroids that came too close. Gas produced by collisions among the debris within the ring is illuminated by ultraviolet rays from the star, causing it to emit a dark red glow which the researchers observed and turned into the image of the ring.
A Stony Brook University-led team of evolutionary biologists has discovered that the oldest known nectar-drinking bat fossil, Palynephyllum antimaster, was probably omnivorous.
94-year-old Wade Gladden came to UAB with only 20 percent heart function, but physicians put a monthslong plan in place to restore function — and the Alabama resident hit every mark along the way.
Two University of Notre Dame anthropologists looked beyond the nuclear family for effects on testosterone levels in men and found that not only spouses, but also other relatives, good friends, colleagues, neighbors and fellow church members can play a role.
In a recent study funded by the U.S. Food and Drug Administration, University of Georgia researchers found produce that contained bacteria would contaminate other produce items through the continued use of knives or graters—the bacteria would latch on to the utensils commonly found in consumers’ homes and spread.
In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester, in a surprise discovery, have found the same formula in quantum mechanical calculations of the energy levels of a hydrogen atom. The researchers report their findings in the Journal of Mathematical Physics.
New research from the University of Southampton has found that copper can effectively help to prevent the spread of respiratory viruses, which are linked to severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

Police are less likely to show up at protests involving religious actors or organizations — unless the protesters are fundamentalist Christians, according to a new study. Notre Dame researchers found fundamentalist Christian groups attracted more police attention than either secular or other Christian groups.
The use of chemical dispersants meant to stimulate microbial crude oil degradation can in some cases inhibit the microorganisms that naturally degrade hydrocarbons, according to a new study led by University of Georgia marine scientists.
University of Wisconsin-Madison researchers have created a molecular structure that attaches to a molecule on highly aggressive brain cancer and causes tumors to light up in a scanning machine. In mouse models of human brain cancer, their tag is easily seen in a PET scanner, which is commonly used to detect cancer.
Patients whose blood pressure target was lowered by medications to reach a systolic goal of 120 mmHg had their risk for heart attack and heart failure reduced by 38 percent, and their risk for death lowered by 27 percent. Aggressive treatment appeared to be as effective for adults age 75 and older as for adults age 50-74, according to results from the Systolic Blood Pressure Intervention Trial (SPRINT) presented at the American Heart Association meeting and published online in the New England Journal of Medicine (NEJM) on Nov. 9, 2015.
The thickness of the cortex in a region of the brain that specializes in facial recognition can predict an individual's ability to recognize faces and other objects.
The blood-brain barrier has been non-invasively opened in a patient for the first time. A team at Sunnybrook Health Sciences Centre in Toronto used focused ultrasound to enable temporary and targeted opening of the blood-brain barrier (BBB), allowing the more effective delivery of chemotherapy into a patient’s malignant brain tumor.
Diets high in meat may lead to an increased risk of developing renal cell carcinoma (RCC) through intake of carcinogenic compounds created by certain cooking techniques, such as barbecuing and pan-frying.
The firsthand accounts of 19 Texas veterans who helped liberate World War II Nazi concentration camps now can be seen and heard on Baylor University’s Institute for Oral History (IOH) website using a new video indexing tool that allows a rare type of access to their compelling stories.
A groundbreaking new study shows that cougars, also known as mountain lions and pumas, are likely to recolonize portions of habitat in the middle part of the United States within the next 25 years. It is the first study to show the potential “when and where” of the repopulation of this controversial large predator.
Using Hubble Space Telescope images, astronomers have conducted a "cosmic archeological dig" of our Milky Way's heart, uncovering the blueprints of our galaxy's early construction phase. The researchers uncovered for the first time a population of ancient white dwarfs -- smoldering remnants of once-vibrant stars that inhabited the Milky Way's core.
A group of scientists have developed a three-point plan to ensure the world’s protected areas meet new biodiversity targets set by the 193 signatory nations of the Convention on Biological Diversity's (CBD).
In the long term, cognitive behavior therapy is more effective at treating seasonal affective disorder that light therapy, considered the gold standard, a study to be published in the American Journal of Psychiatry found. Two winters after the initial treatment, 46 percent of research subjects given light therapy reported a recurrence of depression compared with 27 percent of those who were administered CBT. Depressive symptoms were also more severe for those who received light therapy.
Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and will publish in Nature.
The evolution of male songbirds as the colorful consorts of drab female partners is more complicated than long thought, says a McMaster researcher on a team that looked at nearly 6,000 species for a massive study published in the journal Nature.
Discovery greatly expands the known distribution of the fungus that causes white-nose syndrome, which has decimated bat populations in North America
UC San Diego paper finds young adults are more envious than older adults. They are more envious over looks and for a wider range of other reasons, too. It also appears that both men and women are more likely to envy someone who is of their own gender and approximately their own age
Used alone, a cell phone app that tracks exercise, calories and weight loss goals is, on average, not enough to create meaningful weight loss in young adults, according to new research from Duke Medicine.
Global Temperature Report: October 2015
The highest-resolution radar images of asteroid 2015 TB145's safe flyby of Earth have been processed and yield new information about its surface features.
Diamonds may not be as rare as once believed, but this finding in a new Johns Hopkins University research report won’t mean deep discounts at local jewelry stores.
New research shows that brain responses to written food words differ between lean individuals and those with obesity, and suggests that both stress and genetics could influence excess eating. The pair of studies led by Susan Carnell, PhD, member of The Obesity Society (TOS) and Assistant Professor of Psychiatry and Behavioral Sciences at Johns Hopkins University School of Medicine, reinforces the need to better understand how the external food environment interacts with our biology, and may aid the development of behavioral interventions to help individuals with obesity or those at high risk for the disease. The findings will be unveiled during an oral presentation on Tuesday, Nov. 3, and a poster presentation on Wednesday, Nov. 4, at The Obesity Society Annual Meeting at ObesityWeekSM 2015 in Los Angeles, CA.
Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers at Université Sainte-Anne and the University of Montreal revealed today.
The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
Twenty-five boxes of Velvet Underground material were recently donated to the library’s Division of Rare and Manuscript Collections at Cornell University by collector and author Johan Kugelberg.
A study in the Nov. 2 issue of Proceedings of the National Academy of Sciences is the first to fully document the demographic impacts of West Nile virus on North American bird populations. Data from bird-banding stations shows more species were hit than suspected, and half of those have yet to recover.
In their soon-to-be-published study, two Texas Tech University researchers said some of the venomous contents in the bats’ saliva likely evolved by recruiting ancestral genes to produce new transcript molecules rather than by creating completely new gene sequences.
What people believe they want and what they prefer are not always the same thing. When outperformed as an element of romantic attraction, the difference between affinity and desirability becomes clearer as the distance between people gets smaller.
For centuries, cod were the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks are on the verge of collapse, hovering at 3-4% of sustainable levels. Even cuts to the fishery have failed to slow this rapid decline, surprising both fishermen and fisheries managers.
A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old, may be evidence for the presence of giant, unseen planets.
In the recent sci-fi hit, The Martian, the main character, astronaut Mark Watney (played by Matt Damon), manages to grow potatoes on the planet with a mix of ingenuity, science, and a bit of Hollywood make-believe. Could it work?
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day—from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we’re not sure precisely how.
If you don’t have health insurance, or your insurance coverage still leaves you with big bills, hospitals are supposed to let you know if you qualify for free or reduced-price care, and to charge you fairly even if you don’t. (That is, if they want to keep their tax-free nonprofit status.) But a new study finds many nonprofit hospitals have room to improve.
Chemical changes in brain cells caused by disturbances in the body’s day-night cycle may be a key underlying cause of the learning and memory loss associated with Alzheimer’s disease, according to a University of California, Irvine study.
Recent research on the electric eel by Vanderbilt University biologist Ken Catania has revealed that it is not the primitive creature it has been portrayed. Instead, it has a sophisticated control of the electrical fields it generates that makes it one of the most remarkable predators in the animal kingdom.
