Disks, spikes and clouds: A peek into a black hole's back yard

The first direct detection of gravitational waves in 2015 has opened a new window on the universe, enabling in particular the observation of the merger of pairs of massive black holes. This young field of research has matured ...

Buckle up: A new class of materials is here

Usually, the two characterizations of a material are mutually exclusive: something is either stiff, or it can absorb vibrations well—but rarely both. However, if we could make materials that are both stiff and good at absorbing ...

Microbot toys demonstrate how biological machines move

By connecting small self-propelling toys in a chain, researchers at the UvA Institute of Physics have found the key to studying the movement of microscopic organisms and molecular motors inside our cells.

Novel nanocages for delivery of small interfering RNAs

Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation ...

How to overcome noise in quantum computations

Researchers Ludovico Lami (QuSoft, University of Amsterdam) and Mark M. Wilde (Cornell) have made significant progress in quantum computing by deriving a formula that predicts the effects of environmental noise. This is crucial ...

Biologists develop new record bright red fluorescent protein

To understand why a cell divides, secretes hormones or transmits a signal to another cell, biologists often use a trick. They attach colored lights to the proteins of interest, so that they can follow the movements and interactions ...

Graphene grows—physicists find a way to visualize it

Graphene is one of the strongest materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the ...
