Jellyfish-like robots could one day clean up the world’s oceans

Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.

A model that uses human prompts and sketches to generate realistic fashion images

Artificial intelligence (AI) recently started making its way into many creative industries, for instance, in the form of tools for digital artists, architects, interior designers and image editors. In these contexts, AI can automate processes that are tedious or time consuming, while also potentially inspiring artists and facilitating their creative process.

Cryo-imaging lifts the lid on fuel cell catalyst layers

Proton-exchange membrane fuel cells (PEMFC), which are being developed for use in electric vehicles, rely on nanoparticles called catalysts to trigger electricity-producing reactions between hydrogen and oxygen. Most PEMFC catalysts contain platinum—a scarce and precious metal. There is therefore a pressing global need to develop catalysts that can generate the most power while minimizing platinum …
