Our shift towards renewable energy relies on battery technology. Governments all over the world have poured money into battery research, which is why science press headlines are filled with new, eye-popping headlines promising a new revolution in battery technology each week. Most of that news is just hype, but science is actually bringing change to the world of batteries. @skdh has a look.

US Military Interested in New Form Of Magnetism

One of the most surprising pieces of science news we've covered in the past years was the discovery of a new form of magnetism, the so-called “altermagnetism”. It was even more surprising to see that the US-military organization DARPA issued a Request for Information on the topic, basically a pre-emptive inquiry for further research. Just why DARPA is interested in the topic is anyone’s guess -- in particular, they might be interested because altermagnetic materials have a potential to improve electronic devices. This is because they store information in magnetic configurations without producing a net magnet field.

Figure: Altermagnetism works by a local correlation of atomic magnetic moments that causes no net magnetisation. It is distinct from the more common types of ferromagnetism and antiferromagnetism.
