More Information As semiconductor architectures evolve beyond classical transistor scaling into heterogeneous integration, chiplet-based design, and true 3D stacking, heat management has shifted from a secondary design consideration to a defining constraint on system performance. At the same time, power densities continue to rise while materials and device layers become thinner, creating thermal pathways that…

But the Swift spacecraft will surely crash back to Earth, likely before the end of this year, without a reboost. That’s where Katalyst comes in. The company’s robotic servicing spacecraft, named Link, will attempt to rendezvous and dock with the Swift satellite, then raise its altitude to give the observatory a new lease on life….

Six decades ago, pioneering oceanographer and conservationist Sylvia Earle made a bittersweet discovery while diving off Chile’s oceanic islands with the US National Science Foundation vessel, the Anton Bruun. She found the remains of a baby fur seal, one of the world’s most isolated aquatic mammals. Endemic to the Juan Fernández archipelago, in the Pacific…
