Water-to-land transition in early tetrapods
The water-to-land transition is one of the most important major transitions in vertebrate evolution. However, there is still uncertainty about when the water-land transition took place and how terrestrial early tetrapods really were. A new paper in Nature addresses these questions and shows although these early tetrapods were still tied to water and had aquatic features, they also had adaptations that indicate some ability to move on land.

Lizard skull fossil is new and 'perplexing' extinct species
A new species of extinct lizard, Kopidosaurus perplexus, has been described by a graduate student at The University of Texas at Austin. The first part of the name references the lizard's distinct teeth; a 'kopis' is a curved blade used in ancient Greece. But the second part is a nod to the 'perplexing' matter of just where the extinct lizard should be placed on the tree of life. (2020-11-02)

Chemical scissors snip 2D transition metal dichalcogenides into nanoribbon
One of the biggest challenges in making hydrogen production clean and cheap has been finding an alternative catalyst necessary for the chemical reaction that produces the gas, one that is much cheaper and abundant than the very expensive and rare platinum that is currently used. Researchers in Korea have now found a way to 'snip' into tiny nanoribbons a cheap and plentiful substance that fits the bill, boosting its catalytic efficiency to at least that of platinum.
