Fingerprinting proteins with force

What if we could identify proteins as easily as we can sequence DNA and RNA? Perhaps soon we will, thanks to new DNA Nanoswitch Calipers. DNA Calipers create a unique ‘fingerprint’ for peptides (the building blocks of proteins) by repeatedly applying f…

A new Earth bombardment model

A team has updated its asteroid bombardment model of the Earth with the latest geologic evidence of ancient, large collisions. These models have been used to understand how impacts may have affected oxygen levels in the Earth’s atmosphere in the Archea…
