An article published in the journal “Science” describes a research that states the importance of the mechanism called post-translational modification (PTM) in evolution. An international team led by Pedro Beltrao of the European Molecular Biology Laboratory, European Bioinformatics Institute (EMBL-EBI) and by Professor Judit Villen of the University of Washington investigated in particular phosphorylation obtaining information also useful in medical research such as that on cancer.
An article published in the journal “Current Biology” describes a research on a species of reptile that was called Triopticus primus. A group of paleontologists led by Michelle Stocker of Virginia Tech College of Science studied this reptile that lived about 230 million years ago, noting several features similar to those of pachycephalosaur dinosaurs that lived 100 million years later. The research also revealed other similarities between animals contemporary to Triopticus primus and dinosaurs that lived millions of years later.
An article published in the journal “PeerJ” describes the discovery of a new species of pterosaur that was called Allkauren koi from the early Jurassic period. A team of scientists discovered a partial skeleton in the Cañadón Asfalto Formation, in the province of Chubut, Patagonia, Argentina, with a braincase in excellent conditions. For this reason its study can provide new information about the origins and evolution of these flying reptiles.
An article published in the journal “Nature” describes a research on the evolution of from fins to hands. A team of scientists coordinated by paleontologist and developmental biologist Neil Shubin of the University of Chicago, Illinois, used the CRISPR-Cas9 genetic engineering technique to show that the same cells that generate fish fin rays have a central role in the formation of tetrapods fingers and toes.
An article published in the journal “Current Biology” describes a research on an ancient cetacean called Echovenator sandersi that shows how these marine mammals’ ultrasonic hearing is very ancient. A team of scientists led by Morgan Churchill of New York Institute of Technology in Old Westbury, New York, used modern scanning techniques to analyze the very well preserved ear of a fossil dating from the Oligocene period.
