The Earth has one less asteroid to worry about thanks to the research of an international team of scientists at the Arecibo Observatory in Puerto Rico.

Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA's MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere.

The MAVEN team was surprised to find that the atmosphere pulsed exactly three times per night, and only during Mars' spring and fall. The new data also revealed unexpected waves and spirals over the winter poles, while also confirming the Mars Express spacecraft results that this nightglow was brightest over the winter polar regions.

A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United States from 2012 to 2018. Researchers examined 11 different animal species to test for 17 different substances in animals found on the shores in North Carolina and Florida.

Every night on Mars, when the sun sets and temperatures fall to minus 80 degrees Fahrenheit and below, an eerie phenomenon spreads across much of the planet's sky: a soft glow created by chemical reactions occurring tens of miles above the surface.

An astronaut standing on Mars couldn't see this "nightglow"--it shows up only as ultraviolet light. But it may one day help scientists to better predict the churn of Mars' surprisingly complex atmosphere.

As the world's most popular shoe, flip-flops account for a troubling percentage of plastic waste that ends up in landfills, on seashores and in our oceans. Scientists at the University of California San Diego have spent years working to resolve this problem, and now they have taken a step farther toward accomplishing this mission.

CHAMPAIGN, Ill. -- Owners of electric multicookers may be able to add another use to its list of functions, a new study suggests: sanitization of N95 respirator masks.

The University of Illinois, Urbana-Champaign study found that 50 minutes of dry heat in an electric cooker, such as a rice cooker or Instant Pot, decontaminated N95 respirators inside and out while maintaining their filtration and fit. This could enable wearers to safely reuse limited supplies of the respirators, originally intended to be one-time-use items.

Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study.

Research led by the University of Leeds, in collaboration with the National Institute of Water and Atmospheric Research (NIWA) in New Zealand, mapped Southern Alps ice loss from the end of the Little Ice Age -- roughly 400 years ago -- to 2019.

Imagine if there were, say, 600 species of giraffes: some the size of a shrew, some three stories tall, some with purple spots. Of course, many giraffes could be found in Africa, but suppose there were reports of rare ones, wandering high in the mountains of the remote tropical island of New Guinea.

TAMPA, Fla. (Aug. 7, 2020) -- Despite frequent news announcing "medical breakthroughs," advancements in biomedical and clinical science typically happen incrementally. Scientists refine our understanding of how the world works by harnessing new tools and data that can challenge conventional thinking - a continual process of revision that elicits new answers to old questions, and often poses different questions.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state. This census helps researchers understand how and when a stellar embryo transforms to a baby star deep inside a gaseous egg. In addition, the team found a bipolar outflow, a pair of gas streams, that could be telltale evidence of a truly newborn star.
