What paths do quantum particles, such as atoms or photons, follow through quantum state space? Kater Murch of Washington University in St. Louis has used an "artificial atom" to continuously and repeatedly record the paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings.
While surveying a series of binary stars with the ALMA telescope, astronomers uncovered a striking pair of wildly misaligned planet-forming disks in the young binary star system HK Tau.

Blueberries pack a powerful antioxidant punch, whether eaten fresh or from the freezer, according to South Dakota State University graduate Marin Plumb. Anthocyanins, a group of antioxidant compounds, are responsible for the color in blueberries, she explains. Since most of the color is in the skin, freezing the blueberries actually improves the availability of the antioxidants.
In a study published online today by The American Journal of Sports Medicine and available in an upcoming print issue, researchers from the Center for Injury Research and Policy at Nationwide Children’s Hospital and the Colorado School of Public Health found that high school players experienced 1,406 injuries over the 4 academic years from 2008 through 2012. The overall injury rate was 20 per 10,000 lacrosse competitions and practices.
The latest work from a Kansas State University philosopher appears in the scientific journal Proceedings of the National Academy of Sciences of the United States of America, which is a rarity for philosophy research.
Woodrats lost their ability to eat toxic creosote bushes after antibiotics killed their gut microbes. Woodrats that never ate the plants were able to do so after receiving fecal transplants with microbes from creosote-eaters, University of Utah biologists found.
Researchers at the Howard Hughes Medical Institute’s Janelia Research Campus have developed a new computational method that can rapidly track the three-dimensional movements of cells in such data-rich images. Using the method, the Janelia scientists can essentially automate much of the time-consuming process of reconstructing an animal's developmental building plan cell by cell.
Omega-3 fish oil might help protect against alcohol-related neurodamage and the risk of eventual dementia, according to a study published in the journal PLOS ONE.
A new study by University of Chicago researchers suggests the difference between love and lust might be in the eyes. Specifically, where your date looks at you could indicate whether love or lust is in the cards. The new study found that eye patterns concentrate on a stranger’s face if the viewer sees that person as a potential partner in romantic love, but the viewer gazes more at the other person’s body if he or she is feeling sexual desire.
Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.

Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers at Washington University School of Medicine in St. Louis report July 16 in Nature.
Heart disease and stroke are the leading causes of death and disability among people with Type 2 diabetes. In fact, at least 65 percent of people with diabetes die from some form of heart disease or stroke, according to the American Heart Association. However, a new study by researchers at Wake Forest Baptist Medical Center suggests that the use of cholesterol-lowering statins may help prolong the lives of people with diabetic cardiovascular disease.
Columbia researchers used Brookhaven Lab supercomputer simulations to discover unexpected transitions in graphene and other promising super materials under strain.
Cigarette smokers are more likely to commit suicide than people who don’t smoke, a relationship that has been attributed to the fact that numerous people with psychiatric disorders, who have higher suicide rates, also tend to smoke. But a new study by researchers at Washington University School of Medicine in St. Louis finds that smoking itself may increase suicide risk and that policies to limit smoking reduce suicide rates.
Research findings from an international team of scientists uncovers details on how a new species of a feathered raptorial dinosaur found in China provides evidence on how large-bodied dinosaurs took to the air.
Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world's largest and most powerful "atom smasher," report the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles.
University of Washington research in 7- and 11-month-old infants shows that speech sounds stimulate areas of the brain that coordinate and plan motor movements for speech. The study suggests that baby brains start laying down the groundwork of how to form words long before they actually begin to speak.
If you consider your friends family, you may be on to something. A study from the University of California, San Diego, and Yale University finds that friends who are not biologically related still resemble each other genetically.
A rugged peninsula in Argentina’s Patagonia region teeming with wildlife has been declared a Biosphere Reserve by the United Nations Environmental, Scientific, and Cultural Organization (UNESCO).
Ithaca College professor Iann Woods researches how genetics influence responses to stimuli that can trigger anxiety, and he’s using zebrafish — a tropical member of the minnow family named for the black stripes on their bodies — to do so. He and his team of student researchers examine how fish with tweaked genes respond to different triggers compared to unmodified fish. The work could someday lead to better, more nuanced medications for anxiety disorders.
SLU Researchers find higher expectations and lack of empathy toward children trigger abuse and neglect.
More than 140 years ago, Charles Darwin noticed something peculiar about domesticated mammals. Compared to their wild ancestors, domestic species are more tame, and they also tend to display a suite of other characteristic features, including floppier ears, patches of white fur, and more juvenile faces with smaller jaws. Since Darwin’s observations, the explanation for this pattern has proved elusive, but now, in a Perspectives article published in the journal GENETICS, a new hypothesis has been proposed that could explain why breeding for tameness causes changes in such diverse traits.
A marketing researcher at the University of Arkansas found that consumers are more likely to forget information within advertisements in the same magazine that show a celebrity endorsing a neutral product.
