Bridging the Climate Science/Action Gap Via Agency - Sciences Po

For many decades, scientists assumed that Mars was geologically inactive. While its surface is covered in features that attest to its volcanic past, all evidence seemed to indicate that Mars was geologically dead. This is consistent with the fact that Mars' crust has no tectonic plates and instead consists of a single plate, making it a "Stagnant Lid" planet. However, with the arrival of NASA's InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander, indications that the planet was still "alive" began to accumulate. Beyond "marsquakes" caused by impactors, InSight detected evidence of tectonic activity from within. In a recent study, scientists at Imperial College London and Columbia University presented seismic evidence that a marsquake originated beneath Valles Marineris. According to InSight's data, the event (S0976a) was caused by rocks slipping along fault lines deep within the crust. These findings suggest that faults formed billions of years ago, when Mars was much more active, are unstable enough to rupture under stress.

Once Harmony was installed, the space station grew into something more like a five-bedroom house.

AbstractArtificial intelligence (AI) increasingly supports clinical decisions, but human oversight is protective only if clinicians recognize and resist erroneous output. We systematically reviewed controlled and real-world studies of clinician responses to incorrect automated advice. Forty-six reports represented 41 independent cohort clusters, including 40 core cohorts. Across three adjusted cohorts, clinician correctness was substantially higher with correct than incorrect automated advice (pooled OR 10.19, 95% CI 7.43–13.98; I² = 0%); a ≥ 2020 sensitivity analysis was similar but imprecise (OR 9.22, 95% CI 2.06–41.13). In four heterogeneous real-world computerized ECG studies, 26.6% of erroneous interpretations were not corrected or recognized (95% CI 6.4–65.6%; I² = 95.8%). Contemporary AI and large language model studies also documented harmful reliance but were too heterogeneous for pooling.

The James Webb Space Telescope's (JWST) newest Picture of the Month shows what the European Space Agency (ESA) describes as a "turbulent cauldron of star formation." The star-forming region named LHA 120-N 159, also known as N159, is located 161,000 light-years away in the Large Magellanic Cloud (LMC). [ Read More ]

Engineers introduce a 3D-printed, hybrid aluminum-and-rubber cloaking device that blocks an object’s thermal signature by guiding heat around it, rendering it invisible to infrared cameras. Credit: University of Illinois Urbana-Champaign. An object doesn’t have to be visible to give away its location. Sometimes, the way it disrupts the flow of heat is enough to reveal that something is hiding there, much to the despair of camouflaged soldiers who have to endure thermal vision drones on the battlefield. Now, engineers have developed a device that can make that thermal signature almost disappear (although sadly it won’t work for infantry).
