Astronauts aboard the International Space Station continue to work on pioneering studies. Recently they have used the pioneering CRISPR-Cas9 technology to carefully edit the DNA of brewer's yeast.

Op-Ed: Are Humans Evolving? The question is back, with new answers

The "Are humans evolving" question is one of those academic flower arrangements. Everybody takes a position, and not much real thinking happens. The relatively new science of genetics is throwing a lot of very large spanners into those positions.

Colliding lasers lead to cheaper proton therapy

A new method capable of doubling of a proton beam produced via laser-based particle accelerators has been developed in Sweden. This could pave the way for lower-cost medical applications, like proton therapy.

Essential Science: Is anxiety linked to our gut microbiome?

Microbiome research has advanced considerably since the first results from the U.S. National Institutes of Health led Human Microbiome Project were released. One area of interest is the connection between our microorganisms and anxiety symptoms.
