Black squirrels evolved when greys and fox squirrels historically bred, Cambridge researchers find.
Scientists have found that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.
Astronomers are using the intriguing TRAPPIST-1 planetary system as a kind of laboratory to model not the planets themselves, but how the coming James Webb Space Telescope might detect and study their atmospheres, on the path toward looking for life beyond Earth.
Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a study published in Applied and Environmental Microbiology and coauthored by professors at the University of Tennessee, Knoxville.
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati.
Video Length: 4:07"Black Holes" is one of the most highly searched terms about our universe. How much of what we think we know about black holes is actually true? Read this story Video Links: Shedding Light on Black Holes -...
About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay. A team of researchers has obtained drilling samples from the Ocean Drilling Project site 1073 and dated them with the ''uranium-thorium-helium technique'' for the first time.
New research details how two highly lethal viruses have greater pathogenic potential when their proteins are combined.
A new study in The Condor: Ornithological Applications finds that currently-available global positioning system (GPS) tracking devices, previously thought to not alter animal survival rates, can decrease greater sage-grouse survival.

Hand-raising monarch butterflies in the midst of a global extinction crisis, Laura Moore and her neighbors gather round in her suburban Maryland yard to launch a butterfly newly emerged from its chrysalis. Eager to play his part, 3-year-old Thomas Powell flaps his arms and exclaims, "I'm flying! I'm flying!"

About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay, an estuary in Virginia and Maryland. From this impact, the nearby area experienced fires, earthquakes, falling molten glass droplets, an air blast and a devastating tsunami.
A coalition of 22 US states and seven cities on Tuesday sued President Donald Trump's administration to block it from easing restrictions on coal-burning power plants.
Scientists have discovered how diatoms—a type of alga that produce 20 percent of the Earth's oxygen—harness solar energy for photosynthesis.

A low-cost intervention aimed at fostering a growth mindset in students gave the students more confidence in their entrepreneurship abilities and helped them persist when challenges arose.
Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.
Experts agree that paper ballots are needed, but eight American states will use completely paperless machines in the 2020 elections.
Scientists have demonstrated a potentially much brighter electron source based on plasma that could be used in more compact, more powerful particle accelerators.

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.
