Researchers stored a photon in an atomic ensemble to enlarge a hybrid entangled state of light, reaching a size metric of 2.4 after correcting for detection loss. Here's what the record covers, how quantumness was verified, and the limits of an unreviewed preprint.
A matter-wave experiment reports a quantum phase of free fall that is consistent with the equivalence principle within the tested regime. However, it is not evidence of a unification between quantum mechanics and gravity, and scientific disputes over the physical origin of the phase remain unresolved.
The LZ detector, located 1,480 meters underground, has observed a single 248 keV nuclear recoil event. While the finding rules out standard WIMP models, its global significance remains at only 2.6σ, and verification continues through unanalyzed data and independent follow-up experiments.
Roughly 15,000 simulations show that irregularities in star streams can arise from the host galaxy's gravity alone, with no dark matter clumps required. The findings challenge the common practice of using optical shape alone to search for dark matter.
Researchers have demonstrated in the lab that static electricity of several thousand volts, generated when water droplets slide down an insulating surface, can electrically break down a metal's protective coating and trigger corrosion. The finding points to a new pathway for rain-induced corrosion distinct from chemical reactions or physical wear.
NASA's Roman Space Telescope has completed its launch and initial deployment. Over the next three months, the mission must still power up its instruments, achieve focus, and validate a ground data network that includes stations in Japan.
An explainer on the optics behind Roman Space Telescope's Hubble-class mirror and wide, repeated sky surveys, its approach to planet-hunting and dark-energy measurement, and what its technology means—and its limits—for future direct-imaging missions.
JWST has discovered a mysterious object in the early universe called "MoM-BH*-1," which turned out to be a "black hole star"—shining like a giant star while harboring a black hole 100,000 times the mass of the Sun at its center. It serves as direct evidence for how supermassive black holes achieved rapid growth in the immediate aftermath of the universe's birth.
