Genome Duplication as Evolutionary Gamble New research highlighted on September 2 details how whole-genome duplication (polyploidy) acts as a high-risk, high-reward mutation. In New Zealand snails (Potamopyrgus antipodarum), recent genome doubling produced three or four chromosome sets instead of the usual two, generating rapid heritable variation that organisms can repurpose. Similar events underlie major innovations … Read more
Roman Space Telescope En Route to L2 NASA’s Nancy Grace Roman Space Telescope launched on 30 August 2026 aboard a SpaceX Falcon Heavy from Kennedy Space Center and is now on a three-month journey to Sun-Earth L2. Early commissioning succeeded: solar arrays, high-gain antenna, sunshade and Coronagraph Instrument powered on by 1 September. The observatory … Read more
Roman Space Telescope Begins Dark Universe Survey NASA’s Nancy Grace Roman Space Telescope launched on 30 August 2026 aboard a SpaceX Falcon Heavy from Kennedy Space Center, beginning a three-month cruise to the Sun-Earth L2 point roughly one million miles away. The observatory pairs Hubble-class infrared resolution with a field of view about 100 times … Read more
IBM Quantum System Demonstrates Advantage with 70 Logical Qubits IBM and University of Chicago researchers reported a quantum computation using 70 error-corrected logical qubits that finished in about 15 minutes. Leading classical methods cannot practically reproduce the result. The team employed a structured circuit design that preserves hardness while enabling error detection and fidelity verification, … Read more
AHR Protein Blocks Nerve Regeneration Researchers at Mount Sinai identified the aryl hydrocarbon receptor (AHR) as a molecular brake that limits axon regrowth after injury. Published in Nature on 28 August, the work shows that blocking AHR in mice with peripheral nerve or spinal cord damage allowed damaged fibers to regenerate and improved movement and … Read more
Betelgeuse’s Long-Sought Companion Imaged Astronomers using ESO’s Very Large Telescope have captured the clearest direct image yet of a stellar companion orbiting Betelgeuse, the red supergiant in Orion. The detection, published 27 August 2026, ends a roughly century-long search and shows the companion is more massive than expected—about two to three solar masses. It stands … Read more
NASA Tests GPS-Free Satellite Navigation Using Orbital Landmarks NASA’s Starling mission has demonstrated FALCON, a system that lets satellites determine their orbits without GPS by treating other spacecraft and debris as optical landmarks. Over three days the payload improved cataloged orbits for more than 200 objects entirely onboard, using star-tracker cameras and an onboard catalog. … Read more
Gravity Holds on Cosmic Scales A new analysis of galaxy-cluster motions using the Atacama Cosmology Telescope shows that gravity weakens with distance almost exactly as Newton’s inverse-square law and Einstein’s general relativity predict, even across hundreds of millions of light-years. The result, published in Physical Review Letters, is the largest-scale test of the gravitational force … Read more
Gravity Holds on Cosmic Scales A new analysis of galaxy-cluster motions using the Atacama Cosmology Telescope has tested gravity across hundreds of millions of light-years and found it follows Newton’s inverse-square law and Einstein’s general relativity almost exactly. The result, published in Physical Review Letters, is the largest-scale test of the gravitational force law to … Read more
