Tracking the origin and evolution of molecules in space
How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

How Dutch houses can become almost energy- and CO2-neutral
How much energy and greenhouse gas emissions can Dutch homes save? Xining Yang uses Leiden as an example and shows with his research how enormous the impact can be. At least, if we work harder on becoming more sustainable. Based on the models he developed, Yang will receive his doctorate on 28 June.

Dangerous microbes in lower level safety lab? A new technique could make it possible
Researchers need to work in specialized environments when they work with dangerous bacteria and viruses. These microbes spread easily, so only in labs with a high biosafety levels they can be studied. Unfortunately, to look at the microbes properly, expensive microscopes are needed that are not always…

Dutch researchers uncover hidden supermassive black hole
An international team of astronomers led by Violeta Gámez Rosas (Leiden University) has observed a supermassive black hole hidden in a ring of dust. This discovery fits the idea that the so-called active centers of galaxies are much more similar than observations show, because the viewing angle from…

Life cycle of comets near other star resembles that of our solar system
The life cycle of comets near the star Beta Pictoris is similar to that of comets in our own solar system. This is the conclusion of a team of astronomers from the Netherlands, France and Brazil. It seems that, just like in our own solar system, there are fewer comets as the star gets older. The researchers,…

What Darwin couldn’t see: Expedition to uncover invisible life in Galápagos
An international research team is to search for invisible life in the Galápagos Islands. The diversity of bacteria and other microscopic organisms may not be evident to the naked eye, but it is essential to nature. To the islands' giant daisies, for instance: unique endemic plants that are currently…
