A common message in use to convey the seriousness of climate change to the public is: "Carbon dioxide levels are higher today than they have been for the past one million years!" This new study by Brian Schubert (University of Louisiana at Lafayette) and coauthors Ying Cui and A. Hope Jahren used a novel method to conclude that today's carbon dioxide (CO2) levels are actually higher than they have...

There is a world of life on the backs of loggerhead sea turtles, and it's more abundant and diverse than scientists knew.

The first astronauts launched by SpaceX declared victory Monday in NASA's cosmic capture-the-flag game.

Plant biologists have long sought a deeper understanding of foundational processes involving kinases, enzymes that catalyze key biological activities in proteins. Analyzing the processes underlying kinases in plants takes on greater urgency in today's environment increasingly altered by climate warming.

The notion of conserving climate change refugia—areas relatively buffered from current climate change that shelter valued wildlife, ecosystems, and other natural resources—is only about 10 years old, but the field has matured enough that a leading journal has prepared a special issue on the topic.

Scientists at the Center for Astrophysics | Harvard & Smithsonian, and the Black Hole Initiative (BHI), have shed light on how black holes grow over time by developing a new model to predict if growth by accretion or by mergers is dominant, according to the results of a study presented today at the virtual 236th meeting of the American Astronomical Society and published simultaneously in The...

Researchers from NOAA and the University of Colorado have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that scientists have relied on for decades to date archaeological sites.

Engineering the climate can help lower temperatures and reduce climate change impacts. New research shows that when accounting for human behavior, climate engineering leads to significant economic and social risks. In a first-of-its-kind laboratory experiment, researchers found that both rational and irrational factors in the decision to fix the climate leads to welfare losses and increased...

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering and materials science and engineering, led a team that synthesized three-dimensional fuzzy graphene on a nanowire template to create a superior material for...

In 2015, Stanford biologist Paul Ehrlich coauthored a study declaring the world's sixth mass extinction was underway. Five years later, Ehrlich and colleagues at other institutions have a grim update: the extinction rate is likely much higher than previously thought and is eroding nature's ability to provide vital services to people.

The melting of glaciers and ice caps in places as diverse as the Himalayas and Andes mountain ranges, the Svalbard island group and the Canadian Arctic Archipelago has the dual effect of raising global sea levels and depleting freshwater resources that serve millions of people around the world.

Men participated more in an active learning course in science, technology, engineering and math, while women reported lower perceptions of their scientific abilities, were more aware of gender identity and more likely to feel judged based on gender, a new Cornell-led study has found.

Some of the most essential processes on the planet involves water and energy entering and leaving cells.

A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University, has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical novae, are responsible for most of the lithium in our galaxy and solar system.

Rains from Tropical Storm Amanda left at least 17 dead and seven missing while causing extensive damage across El Salvador and Guatemala that pushed thousands of people into shelters amid the coronavirus pandemic.

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links might suggest that the early universe could have been spinning, according to a Kansas State University study.

Tropical Storm Amanda, the first of the Eastern Pacific Ocean hurricane season, formed on Sunday, May 31, along the coast of Guatemala and quickly moved inland. NASA's Aqua satellite provided a look at the storm as it was developing.

According to a well-studied but controversial principle known as Bergmann's Rule, species tend to be larger in cold climates and smaller in warm ones. As human impacts heat the planet, will animals shrink over time?

Man's best friend may also be man's best bet for figuring out how environmental chemicals could impact our health. Researchers from North Carolina State University and Duke University's Nicholas School of the Environment used silicone dog tags as passive environmental samplers to collect information about everyday chemical exposures, and found that dogs could be an important sentinel species for...

Britain's meteorological service has confirmed what most people cooped up at home during the coronavirus lockdown may have guessed—May was the sunniest month on record.

The 49ers who panned for gold during California's Gold Rush didn't really know where they might strike it rich. They had word of mouth and not much else to go on.

Charities can now begin accessing millions of pounds more in donations thanks to a small shift in how people can donate.

Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new UBC research.

Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal approval milestone prior to startup.
