Heat used to transform antiskyrmions to skyrmions and back


Scientists discover a way to transform antiskyrmions to skyrmions and back using heat and magnetic fields.

Green hydrogen production for fuel cells and fertilizers


A new method of water electrolysis avoids rare metals, making hydrogen production green and sustainable.

Recipe for hydrogen: sprinkle manganese oxide with iridium atoms, add water


A few iridium atoms also go a long way. When sprinkled on manganese oxide, hydrogen is produced with 95% less iridium!

Brain clock ticks differently in autism


A new brain imaging study shows that autistic severity is linked to how long certain regions of the brain store information.
