This robot helps you lift objects—by looking at your biceps

We humans are very good at collaboration. For instance, when two people work together to carry a heavy object like a table or a sofa, they tend to instinctively coordinate their motions, constantly recalibrating to make sure their hands are at the same height as the other person's. Our natural ability to make these types of adjustments allows us to collaborate on tasks big and small.

K-Athena: a performance portable magnetohydrodynamics code

Running large-scale simulations is a crucial aspect of modern scientific research, yet it often requires a vast amount of computational resources. As we approach the era of exascale computing, which will be marked by the introduction of highly performing supercomputers, researchers have been trying to develop new architectures and codes to meet the huge computational requirements of our times. An important property to consider when developing codes for the exascale computing era is performance portability, which prevents the repeated, non-trivial refactoring of a code for different architectures.

100% renewables doesn't equal zero-carbon energy, and the difference is growing

While 160 companies around the world have committed to use "100 percent renewable energy," that does not mean "100 percent carbon-free energy." The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study published today in Joule. Entities committed to fighting climate change can and should measure the environmental benefits of their renewable strategies accurately, the authors write.
