Described in 2000 and hailed as the oldest known octopus in the fossil record, the specimen dated back to the late Carboniferous period, roughly 311 to 306…

Clinical trial shows gene editing works for β-Thalassaemia, too

Almost as soon as researchers started exploring the capabilities of the CRISPR/Cas9 system, they recognized its potential use in targeted gene editing. But the intervening decades have seen slow progress as people worked to determine how to…
