Tracing ancient cyanobacteria reveals early origins of circadian clocks
Tokyo, Japan (SPX) May 21, 2025 To shed light on the evolutionary roots of the cyanobacterial circadian clock, a Japanese research team has traced the development of timekeeping proteins from ancient bacterial ancestors. Their study focused on the oscillatory behavior of KaiA, KaiB, and KaiC proteins, comparing the mechanisms in modern cyanobacteria to those of ancestral versions. "Extant cyanobacteria utilize a circadian clock to predict the light-dark environmental cycle by Earth's rotation in order to achieve efficient photos ... read more |

Astronomers detect exoplanet on rare perpendicular path around binary brown dwarfs
London, UK (SPX) Apr 22, 2025 Astronomers have identified an unusual exoplanet, 2M1510 (AB) b, which travels on a polar orbit around a unique pair of brown dwarfs. This marks the first confirmed case of a planet circling two stars at a 90-degree angle relative to their orbit, offering fresh insights into planetary dynamics in binary systems. The host objects, both classified as brown dwarfs, lie in a rare category of substellar binaries that eclipse one another as seen from Earth. Brown dwarfs occupy the mass range between lar ... read more
