As COVID-19 surges nationwide, 78% of New York City residents believe it is likely or very likely the city will again experience a resurgence of cases similar to that seen last April. However, the November Presidential election appears to have triggered an optimism among New Yorkers: more than half feel "more hopeful" about the country's economic recovery (55%) and the government's ability to...
People can continue using mineral-based aerosol sunscreens without fear of exposure to dangerous levels of nanoparticles or other respirable particulates, according to Penn State research published in the journal Aerosol Science and Engineering.
Water and air are highly mutable resources that exist in a myriad of physical states and dimensions, and due to their affectivity, these entities participate in a multitude of interactions capable of sustaining life, transforming environments, and shaping human behavior. As air and water circulate between the atmosphere and the landscape through the process of evapotranspiration, humans interact...
The Suzuki cross-coupling reaction is a widely used technique for combining organic compounds and synthesizing complex chemicals for industrial or pharmaceutical applications. The process requires the use of palladium (Pd) catalysts and, as of today, two main types of Pd-based materials are used in practice as heterogeneous catalysts.
Graphene, an atomically thin carbon layer through which electrons can travel virtually unimpeded, has been extensively studied since its first successful isolation more than 15 years ago. Among its many unique properties is the ability to support highly confined electromagnetic waves coupled to oscillations of electronic charge—plasmon polaritons—that have potentially broad applications in...
One Friday evening in 1992, a meteorite ended a more than 150 million-mile journey by smashing into the trunk of a red Chevrolet Malibu in Peekskill, New York. The car's owner reported that the 30-pound remnant of the earliest days of our solar system was still warm and smelled of sulfur.
Fish are thriving and poachers are staying out of marine protected areas around California's Channel Islands, a new population analysis by an Oregon State University researcher shows.

Boris Johnson is set to unveil plans for world-leading emissions UK cuts - but are they enough?
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes.
There would be at least four times as many flightless bird species on Earth today if it were not for human influences, finds a study led by UCL researchers.The study, published in Science Advances, finds that flightlessness evolved much more frequently among birds than would be expected if you only looked at current species.
Electronic tags released in the Ganges river show plastic pollution can travel thousands of kilometres in just a few months.
The chemical composition of glass beads and their morphological characteristics can reveal where they come from. Archaeologists from the University of Geneva analyzed glass beads found at rural sites in Mali and Senegal from between the 7th and 13th centuries AD. The scientists demonstrate that the glass they are made of probably came from Egypt, the Levantine coast and the Middle East. The...
Pathology reports on more than 50 killer whales stranded over nearly a decade in the northeast Pacific and Hawaii show that orcas face a variety of mortal threats—many stemming from human interactions.
Why do leopards have spots and zebras have stripes? Many biologists have tried to answer these questions and have provided interesting hypotheses, including camouflage, thermoregulation, and insect repellent. But how did animals get these skin patterns? It is still difficult to answer this question. Evolutionary mechanisms underlying the diversity of animal colorations, especially complex and...
Brother of former Labour leader spoke at May event in London’s Hyde Park Piers Corbyn, the brother of the former Labour party leader, has been found guilty of breaching emergency health regulations at an anti-lockdown protest in London’s Hyde Park.During the two-day trial in Westminster magistrates court, the 73-year-old weather forecaster and climate change denier argued that his rights to...
