A broken cable caused severe damage at Puerto Rico's Arecibo Observatory, causing a suspension of operations for one of the world's largest single-dish radio telescopes, officials said Tuesday.

The optical vortex plays an increasingly important role in optical information processing. As an information carrier, it improves the capacity of channels and offers an independent aspect for analysis—different from polarization, intensity, phase, and path. A new degree of freedom for encoding and encrypting optical information may be provided via nonlinear optics, using vortex beams known as...

According to research led by The University of Texas at Austin, seasonal rainfall is expected to rise significantly in East Africa over the next few decades in response to increased greenhouse gases.

Scientists at the University of Bath have taken an important step towards understanding the interaction between layers of atomically thin materials arranged in stacks. They hope their research will speed up the discovery of new, artificial materials, leading to the design of electronic components that are far tinier and more efficient than anything known today.

Millions of American homes could become unsellable—or could be sold at significant losses to their senior-citizen owners—between now and 2040, according to new research from the University of Arizona.

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of former Typhoon Mekkhala shortly after it made landfall in southeastern China. Wind shear had torn the storm apart.

A study by WCS and partners produced new analyses to pinpoint the most important forests for biodiversity conservation remaining in Central Africa. The results highlight the importance of the Democratic Republic of Congo (DRC), northern Republic of Congo, and much of Gabon as the most important countries in Central Africa for safeguarding biodiversity and intact forests.

A pair of pandas on loan from China to a Canadian zoo are facing a food shortage as their supply of fresh bamboo dries up, officials warned.

Hundreds of thousands across the Midwest remained without power on Tuesday after a powerful storm packing 100 mph winds battered the region a day earlier, causing widespread damage to millions of acres to crops and killing a 73-year-old woman found clutching a young boy in her storm-battered mobile home.

Scientists have discovered that the larynx, or voice box, of primates is significantly larger relative to body size, has greater variation, and is under faster rates of evolution than in other mammals.

There may soon be a new weapon in the centuries-old battle against anthrax in wildlife thanks to groundbreaking work at the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVMBS).

Severe flooding continues to displace thousands of people in Somalia.

A new animation of night-time imagery from NASA-NOAA's Suomi NPP satellite revealed how the Eastern Pacific Ocean's Elida transformed into a hurricane over a three-day period.

Of ever-increasing concern for operating a tactical communications network is the possibility that a sophisticated adversary may detect friendly transmissions. Army researchers developed an analysis framework that enables the rigorous study of the detectability of ultraviolet communication systems, providing the insights needed to deliver the requirements of future, more secure Army networks.

Scientists have been warning about an 'insect apocalypse' in recent years, noting sharp declines in specific areas—particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what's happening to insects on a larger scale.

Northwestern University researchers have uncovered a new vulnerability in the novel coronavirus' infamous spike protein—illuminating a relatively simple, potential treatment pathway.

Ana Losada, from the Spanish National Cancer Research Centre (CNIO), is the scientist who identified cohesin in vertebrates, a protein that is essential in cell division. Losada has studied cohesin since she identified it in vertebrates in 1998, at the Cold Spring Harbor Laboratory in New York. "It is fascinating," she says. "Now we know that cohesin plays a role in several types of cancer, and a...

The Transportation Security Administration (TSA) has reported that it found 4,432 firearms in carry-on baggage at airport security checkpoints in 2019, and more than 20,000 firearms since 2014. New research published in the INFORMS Journal on Applied Analytics suggests that they could have found even more.

On July 4, NASA's Transiting Exoplanet Survey Satellite (TESS) finished its primary mission, imaging about 75% of the starry sky as part of a two-year-long survey. In capturing this giant mosaic, TESS has found 66 new exoplanets, or worlds beyond our solar system, as well as nearly 2,100 candidates astronomers are working to confirm.

To protect humans against infection, a protein called MARCH8 tags the vesicular stomatitis virus (VSV) for destruction while it merely holds HIV hostage, a new study in eLife shows.

Proteins in human cells do not function in isolation and their interactions with other proteins define their cellular functions. Therefore, detailed understanding of protein-protein interactions (PPIs) is the key for deciphering regulation of cellular networks and pathways, in both health and disease.

NASA's Terra satellite revealed that a wispy looking Tropical Depression 06W in the Northwestern Pacific Ocean was being battered by wind shear. That wind shear is not expected to wane and the storm is expected to weaken.

To the naked eye, metal organic frameworks (MOFs) look a little like sand. But if you zoom in, you will see that each grain looks and acts more like a sponge—and serves a similar purpose. MOFs are used to absorb and hold gases, which is useful when trying to filter toxic gases out of the air or as a way to store fuel for natural gas- or hydrogen gas-powered engines.

Drivers and passengers can inhale significantly lower levels of air pollution by setting their vehicle's ventilation systems more effectively and taking a 'cleaner' route to their destination, a new study reveals.
