A new way of designing auxetic materials

Imagine pulling on the long ends of a rectangular piece of rubber. It should become narrower and thinner. But what if it instead became wider and fatter? Now, push in on those same ends. What if the rubber became narrower and thinner? Imagine pulling on the long ends of a rectangular piece of rubber. It should…

Glimpses of a volcanic world: New telescope images of Jupiter’s moon Io rival those from spacecraft

New images of Jupiter’s volcano-studded moon Io, taken by the Large Binocular Telescope on Mount Graham in Arizona, offer the highest resolution of Io ever achieved with an Earth-based instrument. The observations were made possible by a new high-contrast optical imaging instrument, dubbed SHARK-VIS, and the telescope’s adaptive optics system, which compensates for the blurring…

TEMPO instrument air quality data now publicly available

Air pollution data on a neighborhood scale are now available in near real-time from the TEMPO instrument (Tropospheric Emissions: Monitoring of Pollution). The mission gathers hourly daytime scans of the atmosphere over North America from the Atlantic Ocean to the Pacific Coast and from roughly Mexico City to central Canada. Air pollution data on a neighborhood…
