No we’re not writing about ourselves as some hardened readers may have already guessed. Because we couldn’t achieve what the researchers in these two stories, both from Nature Briefing, have indeed achieved. Sorry guv- we don’t have their intellectual bandwidth . Cognitive intricacy. Brains, in good old fashioned English But we know intelligence when we see it, and we know you do too.
Algorithms design remarkable enzymes Researchers have used computer algorithms to design highly efficient synthetic enzymes from scratch, reducing the number of tedious hands-on experiments needed to perfect them. The products facilitate a chemical reaction that no known natural protein can, with an efficiency similar to that typically achieved by naturally occurring enzymes. One design was also 100 times more efficient than similar enzymes previously crafted using artificial intelligence. In comparison to enzymes that occur in nature, the algorithm’s creations are less complex and can’t grapple with multi-step chemical reactions, but they’re proof that the approach has promise.Nature | 4 min read

The medical potential of designer enzymes will not be lost on readers as intelligent as our own. Yet some discoveries are to be relished not for their use, but for what they tell us about the world and our real place in it Try this for size
Dragon Man was a Denisovan Ancient proteins and mitochondrial DNA extracted from the ‘Dragon Man’ fossil — a cranium found in northeastern China that is at least 146,000 years old — have confirmed that it belonged to a Denisovan, an archaic human group. The fossil is the first skull to be definitively linked to the group, which sheds light on what the ancient people looked like, putting an end to decade-long speculation.Nature | 5 min read

Learning. Reason. Curiosity. Handy, aren’t they? Their absence can lead to different outcomes indeed. As the inhabitants of certain regions of the globe know only too well.
