Five years ago, Stanford postdoctoral scholar Momchil Minkov encountered a puzzle that he was impatient to solve. At the heart of his field of nonlinear optics are devices that change light from one color to another - a process important for many technologies within telecommunications, computing and laser-based equipment and science. But Minkov wanted a device that also traps both colors of light, a complex feat that could vastly improve the efficiency of this light-changing process - and he wanted it to be microscopic.
WINSTON-SALEM, N.C. - Aug. 6, 2019 - The internet can serve as a pathway to diagnosis and care for people who suspect they have a rare condition that has not been identified by their physicians, according to a study by researchers at Wake Forest School of Medicine, part of Wake Forest Baptist Health.
Scandal gone viral has toppled many a leader, and new research shows it may have saved some too.
News and social media seem to thrive on sensationalizing scandal, and prominent CEOs, politicians, world leaders and sports stars often are forced to step down as a result. However, a new study from the University of Notre Dame introduces the role of the "severity gap," showing that when media or public perceptions of a scandal outpace its actual severity, strong-performing leaders are more likely to keep their jobs.
BIRMINGHAM, Ala. - The heart cannot regenerate muscle tissue after a heart attack has killed part of the muscle wall. That dead tissue can strain surrounding muscle, leading to a lethal heart enlargement.
Hamilton, ON (August 8, 2019) - A large international study led by McMaster University shows that low risk pregnant women who intend to give birth at home have no increased chance of the baby's perinatal or neonatal death compared to other low risk women who intend to give birth in a hospital.
The results have been published by The Lancet's EClinicalMedicine journal.
AMHERST, Mass. - Industry figures show the global rate of solar energy installations grew by 30 percent in one recent year, and the average cost of installing solar has fallen from $7 per watt to $2.8 per watt, making rooftop solar attractive to many more homeowners. But the progress of rooftop installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one, say scientists at the University of Massachusetts Amherst.
Australasian palaeontologists have discovered the world's largest parrot, standing up to 1m tall with a massive beak able to crack most food sources.
The new bird has been named Heracles inexpectatus to reflect its Herculean myth-like size and strength - and the unexpected nature of the discovery.
"New Zealand is well known for its giant birds," says Flinders University Associate Professor Trevor Worthy. "Not only moa dominated avifaunas, but giant geese and adzebills shared the forest floor, while a giant eagle ruled the skies.
Dr. Takahiro Yasui (Professor, Nagoya City University) and Dr. Rei Unno (Research fellow, Nagoya City University) in collaboration with Dr. Tsuyoshi Kawabata (Associate Professor, Nagasaki University) have revealed a novel mechanism for kidney stone formation, using the mouse cultured cell, mouse model for kidney stone, and human kidney tissue.
Seeking social status is a central human motivation. Whether it's buying designer clothing, working the way up the job ladder, or making a conspicuous donation to charity, humans often seek and signal social status. Human cooperation and competition aren't mutually exclusive, they are two sides of the same coin.
Staring at seagulls makes them less likely to steal your food, new research shows.
University of Exeter researchers put a bag of chips on the ground and tested how long it took herring gulls to approach when a human was watching them, compared to when the human looked away.
On average, gulls took 21 seconds longer to approach the food with a human staring at them.
