NASA’s Roman and ESA’s Euclid Will Team Up to Investigate Dark Energy

“The two missions will study this as-yet-unexplained phenomenon in complementary ways. A new space telescope named Euclid, an ESA (European Space Agency) mission with important contributions from NASA, is set to launch in July to explore why the universe’s …

New 3D‑printing method builds structures with two metals

“Taking a cue from the structural complexity of trees and bones, Washington State University engineers have created a way to 3D‑print two types of steel in the same circular layer using two welding machines. The resulting bimetallic material proved …

New Driver for Shapes of Small Quark-Gluon Plasma Drops?

“Results point to importance of internal structure of nucleons—and need for new measurements to disentangle other contributions. New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided …
