A team from the National Cancer Research Center (CNIO) led by Manuel Serrano has been the first in the world to make adult cells of a living organism regress in their evolutionary development until they recover characteristics of embryonic stem cells. As the authors of the work explain in the journal Nature, the research has also revealed that these embryonic stem cells obtained directly inside the body have a broader differentiation capacity than those obtained through in vitro culture.
A team of Spanish paleontologists has discovered the most recent dinosaur footprints in Europe on the banks of several Pyrenean rivers. The tracks correspond to the hadrosaurid subspecies known as "duckbill", which would have lived in this place until the end of the Cretaceous, when the impact caused the mass extinction of all non-avian dinosaurs.

Although being thorough in what we do is often considered a virtue, the truth is that perfectionism can become a double-edged sword. Recent studies suggest that the costs of this personality trait outweigh its benefits. These are four scientifically proven drawbacks of being a perfectionist.
OSCAAR is the name of a new NASA program aimed at allowing amateur astronomers to identify new planets outside of our solar system. The search will be based on the observation of bright stars and the record of slight decreases in their brightness caused by the transit of celestial bodies that orbit around them and that are interposed between the observer who is located on Earth and the distant star.

A study released in Cell Metabolism has identified the brain mechanism by which a protein called SIRT1 slows aging and increases longevity. Both effects are also associated with a low-calorie diet, according to the authors, from the University of Washington School of Medicine (USA).
