Wonderbird, the earliest modern bird known to date is identified

The fossil of the “wonderbird” had been found in 2000, near the border between Belgium and the Netherlands. But it was only early this year that a team of researchers named it and published their findings in a Nature journal. The Asteriornis maastrichtensi lived 66,7 million years ago and shared features with both ducks and chickens. This winged bird probably survived the mass extinction event that decimated most dinosaurs and formed the lineage that includes modern birds.

The Nobel Prize in Chemistry 2020

Emmanuelle Charpentier and Jennifer Doudna were awarded this year’s edition of the Nobel Prize in Chemistry for their role in developing the gene-editing tool, CRISP-CAS9. The duo met in the early 2010s and published their groundbreaking paper in Science in 2012. Unlike other gene-editing tools, CRISPR is highly precise and relatively cheap and fast.

Researchers find a new set of human saliva glands

The human body never ceases to amaze. This year, a team of researchers from the Netherlands found a previously unidentified, 3-centimetres-long organ right in the middle of the head, between the nasal cavity and the throat.
