For the first time, researchers have demonstrated that a laser-plasma accelerator can reliably drive a free-electron laser for more than eight hours. Published in Physical Review Accelerators and Beams, the result was achieved ...
The Atlantic current system, or more formally the Atlantic Meridional Overturning Circulation (AMOC), is more likely to weaken than previously thought. That's the conclusion of a new study published in the journal Science ...
The fossil record has given us another new prehistoric species, named Eosphorosuchus lacrimosa (from the Greek personification of the morning star—the planet Venus), a member of the group called Crocodylomorpha, which includes ...
Dramatic droughts linked to the decline of the Classic Maya civilization approximately 800 to 1000 CE may not have required any external trigger, according to a new climate modeling study. Instead, they could have emerged ...
Archaeologists working at the ancient settlement of Stăuceni-"Holm" in northeastern Romania have uncovered a mega-structure measuring 350 square meters dating back about 6,000 years. This is one of the few examples of a massive ...
Because methane has around 80 times the warming potential of CO2 over a 20-year period, it has been a major focus for climate action groups. The Global Methane Pledge, launched at COP26 in November 2021, aims to cut human-caused ...
Sperm whales produce powerful clicks to communicate. To our ears, they sound nothing more than a series of repetitive, mechanical taps. But we could be a step closer to understanding some of their complex communication, as ...
Using observations gathered by the James Webb Space Telescope (JWST), an international team of astronomers have revealed that one supermassive black hole in the early universe must have formed before a galaxy developed around ...
A study published in the Journal of Anthropological Archaeology combined zooarchaeology with multi-isotopic analysis to reveal the diverse life histories of ancient dogs in the Wari Empire (ca. 600–1050 CE). Not only has ...
Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
