A study in Nature Communications has mapped how certain cyanobacteria run oxygen-producing photosynthesis on far-red light, a dim glow near the edge of human vision. The research, led by scientists at Imperial College London, identifies where the unusual pigments sit inside the water-splitting machinery and assigns a specific absorbed wavelength to each one. The finding…

Researchers at Johns Hopkins University have identified a set of ancient brainstem neurons that helps mice focus on important visual information while suppressing distractions. The discovery, reported in Nature Communications, points to a deep brain circuit that may shape attention across vertebrates, including humans. The finding gives scientists a fresh way to think about selective…
The ALMA Observatory has announced a finding that could widen the search for the engines behind some of the Universe’s most elusive particles. Using ALMA observations, astronomers studied a dust-hidden galaxy called JCMT0402−0424, nicknamed Shadow Blaster and found that its extreme brightness appears to come from intense star formation in a compact core. The galaxy…
A study in Science has opened a rare window into one of evolution’s deepest mysteries: how complex animals began to take over Earth’s oceans before the famous Cambrian explosion. The fossils, found in southwest China, include evidence for animals linked to deuterostomes, the great branch of life that includes humans and our closest invertebrate relatives.…
