Figuring out the 3D form of just about any protein recognized to science will quickly be so simple as typing in a Google search. Researchers have used the revolutionary artificial-intelligence (AI) community AlphaFold to predict the buildings of some 200 million proteins from a million species, protecting almost each recognized protein on the planet.

The burning of fossil fuels has formally shifted the composition of carbon isotopes within the air of the Northern Hemisphere sufficient to cancel out a helpful sign from nuclear-weapons testing.
