What Happens If We Stop Using Fossil Fuels Overnight vs. Over Decades
A 2021 Nature Climate Change study found that halting all fossil fuel use overnight would paradoxically trigger a short-term warming spike of 0.5–1°C, because reflective industrial aerosols vanish in weeks while CO₂ lingers for centuries. A phased transition to net zero by 2050 avoids that termination shock and limits peak warming to roughly 1.5°C.
PFAS in Great Lakes Food Webs: 42 Years of Forever Chemicals on Your Plate
A University of Notre Dame analysis of 42 years of biological data found PFAS 'forever chemicals' systematically biomagnifying through every tier of the Great Lakes food web, with Lakes Erie and Ontario showing the highest concentrations—posing a public-health concern for tens of millions of people.
Bipedal Crocodile Relative Had Tiny Arms and a Beak—Not a Dinosaur
A newly described Triassic species called Labrujasuchus expectatus was a genuine crocodile relative that walked bipedally, carried a toothless beak, and had markedly reduced forelimbs—a body plan scientists once assumed belonged exclusively to dinosaurs.
How SpaceX’s Falcon 9 Pushes a 15,000-lb Satellite to Geostationary Orbit
On June 28, a SpaceX Falcon 9 carried the 15,000-pound SiriusXM SXM-11 satellite through three distinct orbital phases to reach geostationary orbit — the most energy-intensive standard destination in commercial spaceflight.
NASA’s $5M Bet on Lunar Internet: Can AiRANACULUS Fix Moon Communications?
NASA has awarded Lowell, MA-based AiRANACULUS a $5 million CCRPP contract to develop AI-driven, heterogeneous communications networks for lunar and deep-space missions — a critical step beyond the overloaded Deep Space Network as Artemis ramps up.
The Wow! Signal: 72 Seconds in 1977 That Science Still Can’t Explain
In 1977, a routine sky survey picked up a 72-second radio signal so unusual it matched every theoretical marker of an intentional interstellar transmission. Nearly 50 years later, it has never been explained — or repeated.Load More
