More efficient vaccine production

Many vaccines contain viruses that are inactivated to prevent them from harming recipients. This is generally achieved by adding chemicals. Now scientists are taking a different approach, using low-energy-electrons to irradiate the pathogens. The advantages of this new method are that it produces no toxic waste and provides a faster and less aggressive way of rendering pathogens inactive.

Protein research: the computer as microscope

Using a combination of infrared spectroscopy and computer simulation, researchers have gained new insights into the workings of protein switches. With high temporal and spatial resolution, they verified that a magnesium atom contributes significantly to switching the so-called G-proteins on and off.

Multiregional brain on a chip

Researchers have developed a multiregional brain-on-a-chip that models the connectivity between three distinct regions of the brain. The in vitro model was used to extensively characterize the differences between neurons from different regions of the brain and to mimic the system's connectivity.
