High winds and heavy rains buffeted coastal Louisiana and Mississippi on Friday as a disorganized and unpredictable tropical weather system churned through the Gulf of Mexico, forcing cancellation of Juneteenth celebrations in Mississippi and Alabama and threatening Father's Day tourism.

An international team led by researchers at Princeton University has uncovered a new pattern of ordering of electric charge in a novel superconducting material.

A new paper in Scientific Reports led by researchers at William & Mary's Virginia Institute of Marine Science challenges increased salinity and seawater temperatures as the established explanation for a decades-long increase in the prevalence and deadliness of a major oyster disease in the coastal waters of the mid-Atlantic.

Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study published in the journal Geoscience Frontiers.

Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission of sound energy quanta, or phonons, has been induced. Such devices, called phonon lasers, have wide potential for application in information processing, as well as classical and quantum sensing of materials. The study is published in the journal Optics Express.

Climate warming plays a larger role than plant genes in influencing the number and identity of fungal species on oak leaves, especially in autumn. Recently published in the journal New Phytologist, this research by ecologists sheds light on how warming and tree genes affect the dynamics of fungal communities across the season.

COVID-19 has changed the world in unimaginable ways. Some have even been positive, with new vaccines developed in record time. Even the extraordinary lockdowns, which have had severe effects on movement and commerce, have had beneficial effects on the environment and therefore, ironically, on health. Studies from all around the world, including China, Europe and India, have found major drops in the level of air pollution. However, to fully understand the impact of anthropogenic causes, it is important... Читать дальше...

In October of 2024, NASA's Artemis Program will return astronauts to the surface of the moon for the first time since the Apollo Era. In the years and decades that follow, multiple space agencies and commercial partners plan to build the infrastructure that will allow for a long-term human presence on the moon. An important part of these efforts involves building habitats that can ensure the astronauts' health, safety, and comfort in the extreme lunar environment.

Professor Alexander Szameit and his group of physicists from the University of Rostock, in collaboration with Professor Stefano Longhi from the Polytechnic University of Milan, discovered a novel and paradoxical behavior of light waves: Despite being tightly confined in a microscopic volume, a new kind of disorder allows optical signals to suddenly show up at far away regions. Such abrupt transport had previously been considered impossible, and challenges the current understanding of light waves. Читать дальше...

Light-driven molecular motors have been around for over 20 years. These motors typically take microseconds to nanoseconds for one revolution. Thomas Jansen, associate professor of physics at the University of Groningen, and Master's student Atreya Majumdar have now designed an even faster molecular motor. The new design is driven by light only and can make a full turn in picoseconds using the power of a single photon. Jansen says, "We have developed a new out-of-the-box design for a motor molecule...

Charles Darwin was a careful scientist. In the middle of the 19th century, while he was collecting evidence for his theory that species evolve by natural selection, he noticed it didn't explain the fancy tails of male peacocks, the antlers paraded by male deer, or why some the males of some species are far larger then their female counterparts.

After being developed via a virtual learning experience, more than 70 experiments built by university students across the United States are ready for flight on NASA suborbital flight vehicles.

Many employees have come to prefer working from home after being forced to do so more than a year ago when the pandemic started. By some estimates, at least one-quarter of employees will still be working remotely multiple days a week at the end of 2021.

An Anglia Ruskin University (ARU) expert has warned that the effects of climate change overseas could have a potentially devastating impact on the economy here in the UK.

Alpha-actinin can cross-link actin filaments and anchor them to the Z-disk in sarcomeres. Sarcomeres are a structural unit of myofibril in striated muscle. The FATZ (filamin, α-actinin- and telethonin-binding protein of the Z-disk) protein can interact with α-actinin and other core Z-disk proteins that contribute to myofibril assembly and maintenance. In a new report now on Science Advances, Antonio Sponga and an international research team in Austria, Germany, Russia, Poland and the U.K. detailed... Читать дальше...

The world's largest ice sheets may be in less danger of sudden collapse than previously predicted, according to new findings led by the University of Michigan.

A trio of researchers from Harvard University, Universidad de Navarra and McGill University has found evidence that suggests fewer women receiving biomedical patents means that fewer inventions for devices or drugs to treat women are being developed. In their paper published in the journal Science, Rembrand Koning, Sampsa Samila and John-Paul Ferguson describe their study of patents awarded to inventors and what they found. Fiona Murray, with MIT, has published a commentary in the same journal issue... Читать дальше...

Each year Lake Oroville helps water a quarter of the nation's crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires.

Much of the American West has been blasted with sweltering heat this week as a high pressure dome combines with the worst drought in modern history to launch temperatures into the triple digits, toppling records even before the official start of summer.

Woodlands along streams and rivers are an important part of California's diverse ecology. They are biodiversity hotspots, providing various ecosystem services including carbon sequestration and critical habitat for threatened and endangered species. But our land and water use have significantly impacted these ecosystems, sometimes in unexpected ways.
