However, new analysis of spacecraft observations in combination with novel laboratory techniques shows that Mars’s red colour is better matched by iron oxides containing water, known as ferrihydrite. Ferrihydrite typically forms quickly in the presence of cool water, and so must have formed when Mars still had water on its surface.

From the Article:

"The Curiosity rover discovered evidence for long-lived ancient lakes in 2014, and now 10 years later Curiosity has discovered ancient lakes that were free of ice, offering an important insight into the planet's early climate."

Even though it's only research and nowhere near silicon in terms of effectiveness, I find the prospect of maybe one day being able to print simple circuits very exciting :)

I attended a sourdough baking course yesterday, and this is the result - hot out of the cast iron pot.

I'm usually on the consuming side of things, so it was nice to get a chance to learn the process and make it along a proper baker (although kneading by hand was a tough workout!).

I'll let it cool off a bit, and then get a slice with some cold salty butter :)
