Researchers from the Institute for Quantum Computing at the University of Waterloo and the National Research Council of Canada (NRC) have, for the first time, converted the colour and bandwidth of ultrafast single photons using a room-temperature quantum memory in diamond.
Using state-of-the-art theoretical methods, UCSB researchers have identified a specific type of defect in the atomic structure of a light-emitting diode (LED) that results in less efficient performance. The characterization of these point defects could result in the fabrication of even more efficient, longer lasting LED lighting.
How our billion-year-old cousin, baker's yeast, can reveal -- more reliably than leading algorithms -- whether a genetic mutation is actually harmful.
Surprise discovery of 17-billion-solar-mass black hole in sparse area of local universe.
While sharing toys and fighting with each other, kindergarten children helped researchers understand the patterns and qualities of interactions in social groups. The results were much more complex than the scientists originally predicted.
Astronomers have uncovered one of the biggest supermassive black holes, with the mass of 17 billion suns, in an unlikely place: the cente of a galaxy that lies in a quiet backwater of the universe. The observations, made with the Hubble Space Telescope and the Gemini telescope in Hawaii, indicate that these monster objects may be more common than once thought. The results of this study are released in the journal Nature. To learn even more, join astronomers and scientists during a live Hubble Hangout discussion at 3pm EDT on Thurs., April 7, at http://hbbl.us/z7j.

Hundreds of athletes around the globe are competing in one-mile ice swims. Performance and human physiological response in water 5 degrees Celsius or less has not been well-studied. Researchers will present new data on how age, gender and environmental factors such as wind chill affect ice swimming performance at Experimental Biology 2016.

A new study offers hope for cold-water species in the face of climate change. The study, published today in the Proceedings of the National Academy of Sciences, addresses a longstanding paradox between predictions of widespread extinctions of cold-water species and a general lack of evidence for those extinctions despite decades of recent climate change.

The mouse model mimics aspects of the infection in humans, with high levels of the virus seen in the mouse brain and spinal cord and in the testes of male mice.
A new study addresses a controversial hypothesis regarding the potential ramming function of the sperm whale’s head. This hypothesis was instrumental in inspiring Herman Melville to write the novel Moby Dick but its mechanical feasibility had never been addressed.
A team of international paleontologists demonstrate that ancient mammal relatives known as therapsids were suited to the drastic climate change by having shorter life expectancies and would have had a better chance of success by breeding at younger ages than their predecessors.
A leading cause of the bone-loss disease osteoporosis is hyperparathyroidism. Doctors commonly treat this using a class of prescription drugs called bisphosphonates, which are supposed to strengthen bones. A UCLA study found those drugs actually increase the risk of fracture, meaning that taking them is worse than doing nothing at all. The research also revealed that patients who have surgery to remove the overactive parathyroid glands have fewer subsequent bone fractures.
New research on coral reefs suggests that existing biodiversity will be essential for the successful adaptation of ecosystems to climate change.
Microbiologists based in the Institute for Global Food Security and School of Biological Sciences at Queen’s University Belfast have recently released results that may have answered one of ancient history’s greatest enigmas: Where did Hannibal cross the Alps?
As Virgin America claimed the top spot for the fourth consecutive year, overall U.S. airline performance improved slightly in 2015, according to the 26th annual Airline Quality Rating (AQR), released today (Monday, April 4) at the National Press Club in Washington.
A shocking new report by the Wildlife Conservation Society (WCS) and Fauna & Flora International documents a catastrophic collapse of the world’s largest great ape– the Grauer’s gorilla – due to a combination of illegal hunting around mining sites and settlements, prior civil unrest, and habitat loss.
"The finding also suggests that rural households may be seeking out farmers’ markets as a travel destination rather than as part of a multi-stop shopping trip, as would often be the case with urban consumers," said Alan Hodges, an Extension scientists in the UF/IFAS department of food and resource economics.
A study by economists at North Carolina State University finds that most people are unwilling to rent vacation homes that have a view of offshore wind turbines – and that those who will rent expect steep rental discounts unless the turbines are more than eight miles offshore.

A new study by researchers from Denmark and Canada's York University, published in Geophysical Research Letters, has found that the climate models commonly used to simulate melting of the Greenland ice sheet tend to underestimate the impact of exceptionally warm weather episodes on the ice sheet.
Epilepsy is a neurological disorder that causes seizures of many different types. Recent research from Japan has found that epileptic seizures can be more easily predicted by using an electrocardiogram to measure fluctuations in the heart rate than by measuring brain activity, because the monitoring device is easier to wear. By making more accurate predictions, it is possible to prevent injury or accident that may result from an epileptic seizure. This is a significant contribution toward the realization of a society where epileptic patients can live without worrying about sustaining injury from an unexpected seizure.
Japanese researchers show how thunderbugs provide hints to a sexual mystery.
Research reveals how to benefit the most from online tutorials.
Like an endlessly repeating video loop, horrible memories plague people with post-traumatic stress disorder. But a new study in veterans shows the promise of mindfulness training for enhancing the ability to manage those thoughts if they come up. It also shows the veterans’ brains changed in ways that could help switch off that endless loop.
Two invasive species of tumbleweed have hybridized to create a new species of tumbleweed that University of California, Riverside researchers found has dramatically expanded its geographic range in California in just a decade.

A study published in today's Nature gives estimates of sea levels rising twice what previous studies have warned. The rapid melting of Antarctic's Ice Sheet could raise the sea level as much as three feet by the end of this century. The newer model suggests that sea levels could rise as much as 13 meters by 2500 should the Antarctic Ice Shelf, roughly the size of Mexico, continue to melt.
