Have you heard of reptiles that swim? Such animals used to exist back in the Late Cretaceous period (that is, 98–66 million years ago). Mosasaurs were discovered back in 1764; it quickly became clear that they were marine predators, but the debate still continues on how exactly they swam. A part of the scientific community argues they moved like snakes. Bringing robust analysis and proofs, a recent study demonstrates that Mosasaurs were skilled swimmers, achieving swim speed comparable to sharks.

On a different and more to-the-ground note, researchers have identified a better curative approach for acute leukaemia. The latter is the blood cancer that claims hundreds of lives every year. A comparison between more than 1,000 samples revealed that a drug treatment gives much better remission results. It thus improves survival rates than total body irradiation.
