The effect of aging on cognitive processes such as learning, memory and logical reasoning have so far been studied almost exclusively in people. Using a series of touchscreen tests, Lisa Wallis and Friederike Range of the Messerli Research Institute at Vetmeduni Vienna have now studied these domains in pet dogs of varying ages.
A Drexel University materials scientist has discovered a way to grow a crystal ball in a lab. Not the kind that soothsayers use to predict the future, but a microscopic version that could be used to encapsulate medication in a way that would allow it to deliver its curative payload more effectively inside the body.
People who have self-reported penicillin allergy may have a three times greater chance of suffering from chronic hives. And people who have chronic hives tend to self-report penicillin allergy at a three times greater rate than the general population. Authors of a new study think it's not coincidence.
While academic awareness of African peoples' hunting with poison-tipped arrows extends back for centuries, knowledge of the ingenious practice has been scattered among chemistry, entomology and anthropology texts.
When an endangered orca is in hot pursuit of an endangered salmon, sending out clicks and listening for their echoes in the murky ocean near Seattle, does the noise from the nearby shipping lane interfere with them catching dinner? To find out scientists measured underwater noise as ships passed their study site 3,000 times. This unprecedented characterization of ship noise will aid in the understanding of the potential effects on marine life, and help with possible mitigation strategies.
A multi-institution team of researchers has successfully mapped the genome of Cimex lectularius, the common bed bug. Among the findings, scientists discovered more than 800 instances of genes being transferred from bacteria to the bed bug’s chromosomes.
An international group of physicists led by the University of Arkansas has created an artificial material with a structure comparable to graphene.
Researchers at Case Western Reserve University School of Medicine, UCSF School of Medicine and other institutions have recently uncovered abnormalities in embryonic brain development in mice, including transient embryonic brain enlargement during neuron formation, that are responsible for abnormal adult brain structures and behavioral abnormalities.
A newly upgraded camera that incorporates light sensors developed at Berkeley Lab is now one of the best cameras on the planet for studying outer space at red wavelengths that are too red for the human eye to see.
A faculty member in the University of Georgia’s College of Family and Consumer Sciences found that adults going on a one- to three-week vacation gained an average of nearly 1 pound during their trips. With the average American reportedly gaining 1-2 pounds a year, the study’s findings suggest an alarming trend.
An estimated 1 in 68 children in the United States has autism. The neurodevelopmental disorder, which impairs communication and social interaction skills, can be treated with medications and behavioral therapies, though there is no cure. Now, University of Missouri researchers have found that a medication commonly used to treat high blood pressure and irregular heartbeats may have the potential to improve some social functions of individuals with autism.
A new UCLA study demonstrates that BPS, a common replacement for BPA, speeds up embryonic development and disrupts the reproductive system. The research is the first to examine the effects of BPA and BPS on key brain cells and genes that control organs involved in reproduction.
Researchers assumed that tiny objects would instantly blow up when hit by extremely intense light from the world’s most powerful X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory. But to their astonishment, these nanoparticles initially shrank instead – a finding that provides a glimpse of the unusual world of superheated nanomaterials that could eventually also help scientists further develop X-ray techniques for taking atomic images of individual molecules.
Promising new calibration tools, called laser frequency combs, could allow astronomers to take a major step in discovering and characterizing earthlike planets around other stars. These devices generate evenly spaced lines of light, much like the teeth on a comb for styling hair or the tick marks on a ruler—hence their nickname of "optical rulers."
Building on nearly two decades’ worth of research, a multidisciplinary team at Cornell has blazed a new trail by creating a self-assembled, three-dimensional gyroidal superconductor.
The finding by Stony Brook University researchers, published in Structure, may be a foundation to better understanding the cellular process and age-related disease.
Some of the most widely used commercial chemicals to kill bedbugs are not effective because the pesky insects have built up a tolerance to them, according to a team of researchers from Virginia Tech and New Mexico State University.
Children born to obese women with diabetes are more than four times as likely to be diagnosed with autism spectrum disorder than children of healthy weight mothers without diabetes, new Johns Hopkins Bloomberg School of Public Health research suggests.
University of Notre Dame astrophysicist Nicolas Lehner and his collaborators have now determined that the Smith Cloud, a giant gas cloud plummeting toward the Milky Way, contains elements similar to our sun, which means the cloud originated in the Milky Way’s outer edges and not in intergalactic space as some have speculated.
Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can contract and expand the way muscles do. These functions require polymers with both rigid and soft nano-sized compartments with extremely different properties. Northwestern University researchers have developed a hybrid polymer of this type that might one day be used in artificial muscles; for delivery of drugs or biomolecules; in self-repairing materials; and for replaceable energy sources.
An estimated 15 million Americans suffer from food allergies, many of them children. These are non-trivial concerns, as food allergy or intolerance can cause symptoms ranging from a harmless skin rash to a potentially lethal anaphylactic shock. The good news is that many affected children outgrow their allergy, presumably as the immune system learns to tolerate food initially mistaken as “foreign”.
Understanding and integrating patients’ cultural beliefs into cancer treatment plans may help improve their acceptance of and adherence to treatment in multicultural settings. Researchers examined traditional Maya healers’ understanding of cancer and published their findings online today in the Journal of Global Oncology.
NASA satellites obtained a number of different views of the great winter storm that left many snowfall records from Virginia to New York City from January 22 to 24, 2016. RapidScat provided a look at the strong winds that led to flooding in southern New Jersey, while NASA's Aqua satellite and NASA/USGS's Landsat satellite provided images of the post-storm snowy blanket.
When fast-rising employees quit their jobs for better pay or more responsibility at another organization, the knee-jerk reaction may be to blame their leaving on a bad boss. Although the common perception is that workers join companies but leave managers, new research by a University of Illinois business professor shows that workers leave good bosses, too -- and for companies, there may be a silver lining to their departure.
Using observations by the Hubble Space Telescope, an international research team, including astronomers from the Kavli Institute for Astronomy and Astrophysics and Northwestern University, has for the first time found young populations of stars within globular clusters that have apparently developed courtesy of star-forming gas flowing in from outside of the clusters themselves. This method stands in contrast to the conventional idea of the clusters’ initial stars shedding gas as they age in order to spark future rounds of star birth.
WCS announced today that a team of scientists discovered a new species of chameleon in Tanzania.
Obesity is associated with epigenetic changes that dysregulate memory-associated genes, and a particular enzyme in brain neurons of the hippocampus appears to be a link between chronic obesity and cognitive decline.
A new analysis of ice-core climate data, archeological evidence and ancient pollen samples strongly suggests that agriculture by humans 7,000 years ago likely slowed a natural cooling process of the global climate, playing a role in the relatively warmer climate we experience today.
Contrary to current clinical belief, regular caffeine consumption does not lead to extra heartbeats, which, while common, can lead in rare cases to heart- or stroke-related morbidity and mortality, according to UC San Francisco researchers.
When scientists from McGill University learned that some fish were proliferating in water polluted by oil extraction in Southern Trinidad, they thought they had found a rare example of a species able to adapt to crude oil pollution. But when they tested them, these guppies were actually less adapted to pollution than similar fish from non-polluted areas.
A new study suggests that current ‘hotspots’ of shark activity are at risk of overfishing, and that the introduction of catch quotas might be necessary to protect oceanic sharks.
University at Buffalo engineers are developing hardware and software tools to help underwater telecommunication catch up to its over-the-air counterpart.
Black holes sound too strange to be real. But they are actually pretty common in space. There are dozens known and probably millions more in the Milky Way and a billion times that lurking outside. The makings and dynamics of these monstrous warpings of spacetime have been confounding scientists for centuries.
Nearly 15 percent of patients diagnosed with colorectal cancer were younger than 50, the age at which screening recommendations begin.
A team of researchers has observed the brightest ultra metal-poor star ever discovered. The star is a rare relic from the Milky Way’s formative years. As such, it offers astronomers a precious opportunity to explore the origin of the first stars that sprung to life within our galaxy and the universe.
Research recently published in the journal Plos One is part of a study to measure the psychological predictors of tolerance for tigers in the Bangladesh Sundarbans, where the large carnivores have a rocky and sometimes violent relationship with local communities.
A diet rich in fiber may not only protect against diabetes and heart disease, it may reduce the risk of developing lung disease, according to new research published online, ahead of print in the Annals of the American Thoracic Society.
Life on other planets would probably go extinct soon after its origin, due to runaway heating or cooling on their fledgling planets.
Having the wrong coat color during shorter winters is deadly for snowshoe hares and could lead to a steep population decline by mid-century. However, wide variance in molting times could enable natural selection to work.
A thick blanket of snow covering streets, walkways and rooftops can cause some major stress, but it can also be calming. The world seems quieter and it's not just because people are hibernating inside.
Resembling an opulent diamond tapestry, this Hubble image of Trumpler 14 located 8,000 light-years away in the Carina Nebula, shows a glittering star cluster that contains a collection of some of the brightest stars seen in our Milky Way galaxy.
College students whose parents lay on the guilt or try to manipulate them may translate feelings of stress into similar mean behavior with their own friends, a new study by a University of Vermont psychologist has found. The students’ physical response to stress, which the researchers measured in a laboratory test, influenced the way they carry out that hostility – either immediately and impulsively or in a cold, calculated way.
Juvenile theropod possibly oldest known Jurassic dinosaur from UK.
Researchers at Duke Health are fine-tuning a test that can determine whether a respiratory illness is caused by infection from a virus or bacteria so that antibiotics can be more precisely prescribed.

A new study published in Nature Climate Change pinpoints the temperature increases caused by CO¬2 emissions in different regions around the world.
Adults with long-term exposure to ozone (O3) face an increased risk of dying from respiratory and cardiovascular diseases, according to the study “Long-Term Ozone Exposure and Mortality in a Large Prospective Study” published online ahead of print in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
Latest research reveals why geckos are the largest animals able to scale smooth vertical walls - even larger climbers would require unmanageably large sticky footpads.
Jackie Goordial, a post-doctoral fellow in the Department of Natural Resource Sciences at McGill University has spent the past four years looking for signs of active microbial life in permafrost soil taken from one of the coldest, oldest and driest places on Earth: in University Valley, located in the high elevation McMurdo Dry Valleys of Antarctica, where extremely cold and dry conditions have persisted for over 150,000 years. The reason that scientists are looking for life in this area is that it is thought to be the place on Earth that most closely resembles the permafrost found in the northern polar region of Mars at the Phoenix landing site.
When a child comes home from preschool with a stomach bug that threatens to sideline the whole family for days, why do some members of the family get sick while others are unscathed? According to a Duke Health study published January 19 in the Journal of Infectious Diseases, a person’s resistance to certain germs, specifically E. coli bacteria, could come down to their very DNA.
