Samples from the Bennu asteroid, which is currently more than 200 million miles (322 million kilometers) from Earth, and the Murchison meteorite, which fell to Earth in 1969, both contain molecules that build proteins necessary for life. New research has found that the molecules may have formed through the same process but originated far from one another in the solar system.
The suspect allegedly fired at a pursuing state trooper before fleeing on foot and displaying a firearm during a confrontation with Thurston County deputies
A new study published in Nature Materials reports that researchers have developed an aluminum gallium nitride device that combines light detection, memory and basic processing by controlling charge at polarization interfaces. The device can detect light at the nanowatt-per-square-centimeter level and operate stably at temperatures up to 300°C.
For more than 50 years, engineers have described light in optical fiber using a convenient shortcut, one that works so well it is rarely questioned. Engineers at the University of the Witwatersrand (Wits University) in Johannesburg, South Africa, have now shown that this shortcut hides a small but real effect. A magnet placed beside a multimode fiber, rather than along it, can change the light traveling inside.
In a study published in Optics Communications, a research group led by Yu Tao from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences proposed a new analytical phase readout algorithm for deep frequency modulation interferometry (DFMI).

The oldest pair of compact quasars ever observed has been found only 900 million years after the Big Bang. Scientists say there is no theoretical explanation for how the pair of actively feeding black holes grew so massive at such an early time in the history of the universe. The pair of quasars has been given the Hawaiian nickname Nāpōwawāʻenakaulua.
The LISA (Laser Interferometer Space Antenna) observatory, now in development, will detect gravitational waves, the tiny ripples in space-time caused by orbiting masses. Now two studies led by NASA astrophysicists show in new detail how LISA could reveal a new and unique population of exoplanets—worlds beyond our solar system—throughout our galaxy.
The head of Germany’s Isar Aerospace voiced hope Tuesday that the company could one day overtake Elon Musk’s SpaceX to become the world’s premier space launch company.
A shoebox-sized color detection device could enable precise measurements at record resolution, according to new research led by Adelaide University. An international team exploited an integrating sphere—a highly reflective hollow cavity that causes light to bounce around inside many times before exiting—to demonstrate a device that can measure the color (wavelength) composition of light with extreme precision at a resolution of just 6 femtometers.
Prosecutors said Matthew Farwell sexually abused Sandra Birchmore after meeting her through a police youth program, then killed her in 2021 and staged her death as a suicide
An international team of researchers, led by Jonathan Freundlich (University of Strasbourg, Astronomical Observatory), has revealed how a dense cosmic environment depletes galaxies of their gas. By mapping the molecular gas in a galaxy group located 7 billion light-years away, they found that the galaxies in this group harbor, on average, gas reservoirs reduced by more than half compared to similar isolated galaxies. The results of this study are published in the journal Astronomy & Astrophysics.
A new study suggests that most of Earth’s carbon originated in the outer solar system and didn’t arrive here until the late stages of planetary development. The study, led by researchers at Yale and Columbia, is based upon an analysis of magma droplets called “melt inclusions” from historic volcano eruptions in Hawaii, including the Keanakākoʻi eruptions from 1500 to 1840 and the Kīlauea Iki eruption in 1959.
Researchers at the U.S. Department of Energy’s (DOE) Ames National Laboratory have discovered a way to control the handedness of magnons, tiny magnetic waves that can carry information through materials. By changing the material’s magnetic state with an external magnetic field, they were able to switch magnon behavior, a finding with potential applications in quantum information and quantum computing technologies. Their findings are published in Physical Review Letters.
