A supermassive black hole 6 billion times the mass of the Sun lurks in MRG-M0138, a gravitationally lensed quiescent galaxy seen when the Universe was just 3 billion years old, according to an analysis of data collected by the NIRSpec Integral Field Spectrograph onboard the NASA/ESA/CSA James Webb Space Telescope. This Webb image shows the highly distorted red galaxy MRG-M0138 seen through a foreground...

The Northwest Africa (NWA) 12774, an angrite meteorite discovered in the Sahara Desert, likely in Mauritania, appears to be a fragment of a vanished protoplanet, offering the strongest evidence yet that a large planetary body formed and was later destroyed during the Solar System’s chaotic infancy. This is an artist impression of the protoplanetary disk around HD 107146. Image credit: A. Angelich...

Neolithic people, not glaciers, moved the Altar Stone — the six-ton central sandstone megalith at Stonehenge — from northeast Scotland to Salisbury Plain, according to a new study led by archaeologists from Curtin University and Sheffield Hallam University.

Near-complete bovine skeletons unearthed the Early Pliocene site of Camp dels Ninots in northeastern Spain reveal that the ancestors of today’s buffalo and cattle were already growing to impressive sizes long before humans arrived on the continent.

Euplotes gigatrox, a new species of ciliate collected from a seawater filtration system on the Caribbean Island of Curaçao, can transform into a cannibalistic ‘supergiant,’ raising new questions about the complexity of life at the microscopic scale.

Mathematicians from University College London and the University of California, Davis, have published a mathematical proof that the Universe’s accelerating expansion can be explained without dark energy, dealing a serious blow to the Lambda-cold dark matter model — the standard cosmological model that has stood for nearly 30 years. Alexander et al. provide a mathematical proof that instabilities...

In a small randomized trial in the United Kingdom, adults who added a serving of 100% fruit juice or a smoothie to a healthier diet reported lower depression scores after four weeks. People who drink a glass of 100% fruit juice or a smoothie each day as part of the UK’s 5-a-day healthy eating guidance see improvements in their mental wellbeing.

Scientists have extracted and analyzed proteins from the tooth enamel of six Homo erectus individuals who lived in China roughly 400,000 years ago, offering an unprecedented glimpse into the genetic makeup of one of humanity’s most successful and far-ranging ancestors. Their results suggest that Homo erectus may have carried genetic variants that were later passed to Denisovans and eventually...

Unusual gases rising from geothermal springs within the Kafue Rift of Zambia suggest a deep fracture in Earth’s crust could mark the early stages of a new tectonic boundary. Location map of the extensional zone within the Central African Plateau of Zambia. The Kafue Rift is connected to the Luano and Luangwa rifts to the NE, and the Western branch of the EARS at the Rukwa rift (RRB) and Rungwe...

Chemical traces preserved in ancient rocks indicate that marine environments were deteriorating long before the catastrophe that wiped out vast numbers of species at the end of the Triassic period, around 201 million years ago.
