The Great Cosmic Wiggle: Quasars Reveal Gravity’s Hidden Rhythm

『V』πšƒ『B』Casts┋
Gravitational waves are constantly washing over Earth, but an astrophysicist aims to capture them in an entirely new way—by watching distant quasars appear to wiggle due to spacetime distortions. Using data from the Gaia satellite, he’s searching for three-dimensional effects that previous techniques might have missed. Exploring a New Method to Detect Gravitational Waves Astrophysicist [...]

Genomic studies show Papua New Guineans are closely related to Asians, shaped by isolation, adaptation, and Denisovan heritage. Papua New Guineans are living proof of how isolation, ancient genetic mixing, and life on remote islands can preserve a distinct chapter of human history. A group of European scientists has recently clarified their genetic origins, applying [...] http://dlvr.it/TMnnzY

It feels like the price of most things has increased lately — that's the rub with inflation. While many Americans who have experienced the rollercoaster of capitalism before have some familiarity with cost instability around staples like food and gas, inflation, SpaceX claims, is also behind some upcoming changes to its satellite internet provider, Starlink.  "Due to excessive levels of inflation, the price of the Starlink kit is increasing from $499 to $549 for deposit holders, and $599 for all new orders, effective today," an email forwarded to Engadget states. "In addition, the Starlink monthly service price will increase from $99 to $110. The new price will apply to your subscription on 4/22/2022."  The email reminds customers that, within their first year they can cancel and receive "a partial refund of $200," or a full refund if their equipment was received within the last 30 days. Several other customers have posted identical emails on Twitter...

Sydney, Australia (SPX) Jan 01, 2026 A collaboration led by Macquarie University has reconstructed how errors develop and spread inside working quantum computers, revealing that noise can link events across time rather than appearing as isolated random faults. The researchers show that small inaccuracies in quantum processors can linger, evolve and correlate across different computational steps, creating a form of temporal me http://dlvr.it/TQ5nB9
