The NASA/ESA/CSA James Webb Space Telescope has resolved roughly 16.5 million stars in the edge-on spiral galaxy Messier 82 (M82, NGC 3034 or the Cigar Galaxy), offering astronomers an unprecedented look inside a galaxy undergoing an intense burst of star formation. This Webb image shows the edge-on spiral galaxy Messier 82. Image credit: NASA / ESA / CSA / Adam Smercina, STScI, Tufts / Thomas Williams,...
Zircon crystals and impact-altered minerals show that a massive asteroid slammed into what is now the Pilbara region of Western Australia about 3 billion years ago. The North Pole Dome crater: (A) simplified map of the East Pilbara Terrane (EPT, Western Australia), showing Paleoarchean granite domes (pink) and greenstone belts (greens and blues); the North Pole Dome (NPD) lies near the terrane center;...
Scientists have uncovered compelling new evidence that early human ancestors, likely Homo erectus, were deliberately bringing fire into Wonderwerk Cave in South Africa as far back as 1.79 million years ago.

Paleontologists working in Brazil have identified a previously unknown species of archosauriform that lived about 240 million years ago and may belong to a poorly understood group of ancient reptiles that closely resembled the ancestors of crocodiles and dinosaurs.

The way humans laugh — in rapid, rhythmically timed bursts — is not uniquely ours. New research by the University of Warwick and the University of Portsmouth shows that all great apes, from orangutans to gorillas to chimpanzees, share the same fundamental timing structure in their laughter, suggesting that the common ancestor of all living great apes was already laughing in a recognizable...
Physicists with LHCb Collaboration at CERN’s Large Hadron Collider (LHC) have detected the elusive Ωcc⁺ baryon, a particle containing two charm quarks and one strange quark, completing a long-sought family of doubly charmed baryons first predicted over half a century ago. An artist’s impression of the doubly charmed Ωcc⁺ baryon. Image credit: Daniel Dominguez / CERN. “Quarks are basic...
Researchers at Guangzhou Medical University tracked nearly 88,000 people for over eight years, finding a significant link between daytime light exposure and reduced dementia rates. Zheng et al. uncovered a link between higher levels of daytime light exposure and a lower risk of dementia.

Scientists have generated genetic data from 27 Neanderthals who lived in Belgium and France less than approximately 52,500 years ago, painting a richer and more surprising portrait of how our closest hominin cousins organized their lives before their disappearance. Reconstruction of a Neanderthal. Image credit: Neanderthal Museum. Neanderthals lived in Europe and western Asia from at least around...
