A fin whale was spotted near Grand Manan, entangled in a navigation buoy. It's something rescuers say they have never seen...
The five main party leaders met for the first and only English debate of this election campaign Thursday night and clashed over the country's most pressing problems, from climate change to fractious foreign...
Researchers have designed new metasurfaces using nanoscale techniques inspired by kirigami that could offer a new chip-based way to achieve nanoscale control of light, which could lead to better optical displays, information encoding and digital light processing.
After 20 years of trying, scientists doped a 1D copper oxide chain and found a surprisingly strong attraction between electrons that may factor into the material's superconducting powers.
Black bears (Ursus americanus) reproduced at a younger age in urban areas and were nearly twice the size of bears in national forests shortly after their first birthdays.
Roadside construction -- be it a detour, a closed lane, or a slow weave past workers and equipment -- work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users.
Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But surrounding this massive ice sheet, which covers 79% of the world's largest island, is Greenland's rugged coastline dotted with ice capped mountainous peaks. These peripheral glaciers and ice caps are now...
Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel.
A small subset of people, known as controllers, are able to suppress HIV naturally, without the need for medication. A small percentage of controllers ultimately lose the ability to suppress the virus. Researchers have found that aborted control is likely due to HIV-specific T cells losing the ability to replicate and kill infected cells, which can happen years before.
The shea tree is best know as a source for a multimillion-dollar ingredient used in cosmetics, personal care products, pharmaceuticals and chocolate. But for hundreds of thousands of African families living in the 'shea belt' it is also a crucial source of nutrition and income. Despite its increasing demand, the slow-growing shea tree is being threatened by other cash crops and its preservation...
Beckman researchers paired microscopy with artificial intelligence to develop a COVID-19 test that's fast, accurate, and cost-effective. All we need to do is say "ahh."
Ohm's law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the material—the negatively charged carriers—move in a disordered fashion and largely independently of each other. Physicists find it far more interesting, however, when the charge carriers influence...
The reusable cloth masks people have been using for the past year or more may look a little worse for the wear. But new research from the University of Colorado Boulder finds that washing and drying them doesn't reduce their ability to filter out viral particles.
The shea tree is a vital social and economic crop that is best known for the popular product shea butter—a multimillion-dollar ingredient used in cosmetics, personal care products, pharmaceuticals and chocolate. For hundreds of thousands of African families living in the "shea belt" it is also a crucial source of nutrition and income. Despite its increasing demand, the slow-growing shea tree is...
Black bears (Ursus americanus) reproduced at a younger age in urban areas and were nearly twice the size of bears in national forests shortly after their first birthday, researchers from North Carolina State University and the N.C. Wildlife Resources Commission found in a new study.

What do shooting stars and astronaut safety have in common?
Previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States as fire activity continues to increase, according to researchers from Penn State and the U.S. Forest Service.
Protected forests are unlikely to be cut down when they are surrounded by intact forests. Conversely, the more degraded the boundaries of a protected area are, the more likely that deforestation will encroach into the protected forest as well.
New research more than doubles the estimated volume of ancient, salty groundwater stored deep within Earth's crust.
High-power laser pulses focused to small spots to reach incredible intensities enable a variety of applications, ranging from scientific research to industry and medicine. At the Berkeley Lab Laser Accelerator (BELLA) Center, for instance, intensity is key to building particle accelerators thousands of times shorter than conventional ones that reach the same energy. However, laser-plasma...
