Infrared avalanche photodiodes from bulk to 2D materials

The avalanche multiplication effect can be used to detect low-power optical signals and even single photons due to the amplification mechanism within all main ranges: near- (NIR), short- (SWIR), mid- (MWIR) and long wavelength ...

Searching for dark matter with the world's most sensitive radio

Since the 1960s there has been plenty of evidence to support the existence of dark matter through astrophysical and cosmological observations, and at this point we're very confident that it exists. The question remains, though: ...

Getting protein factories to run—How deubiquitinating enzymes moonlight as Fubi proteases

The small protein ubiquitin is particularly famous for marking proteins for degradation but it has also been shown to regulate virtually all cellular processes. In parallel to the ubiquitin system various other ubiquitin-like ...
