Minor genetic change creates unattractive female moths

Sex pheromones are chemical compounds released by an organism to attract potential mates. For moths in particular these sex pheromones are very important for mate recognition, as they rely completely on scent signal rather ...

Bacteria can survive starvation in zombie mode

Bacteria that are exposed to a hostile environment, for example with antibiotics or very few nutrients, can sometimes survive by 'going to sleep." Biologists from the University of Amsterdam (UvA) have discovered an unknown, ...

Discovering new particles using black holes

Some theories that go beyond the Standard Model of particle physics predict the existence of new ultralight particles, with masses far below the lightest known particles in nature. These particles have such very weak interactions ...

Nucleation of liquids visualised

Researchers from the UvA's Institute of Physics (IoP) and Leiden University have found a new way to visualise and measure the nucleation process responsible for the formation of liquid droplets in vapour. Their findings, ...

Efficient light conversion with perovskite nanocrystals

Perovskites are a family of crystals that show promising properties for applications in nanotechnology. However, a property called carrier multiplication, an effect that makes materials much more efficient in converting light ...

A new era in the quest for dark matter

Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much ...

Mountains create biodiversity

Mountains are among the most biodiverse places on Earth, but scientists have struggled to fully understand why they are so important in creating high species richness. An international research team, including four scientists ...

Quantum LEGO—building ultracold molecules

Cooling matter is not easy. Atoms and molecules have the tendency to jump around, to rotate and to vibrate. Freezing these particles by slowing them down is a complicated process. For individual atoms, physicists have figured ...
