In the soils of the world's cereal fields, a family tussle between related species of fungi is underway for control of the crops' roots, with food security threatened if the wrong side wins. Beneficial fungi can help plants ...

Researchers develop module for quantum repeater

Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. This constitutes a basic building block for transmission of quantum ...

How bacteria behave differently in humans compared to the lab

Most of what we know today about deadly bacteria such as Pseudomonas aeruginosa was obtained from studies done in laboratory settings. Research reported May 14 in the journal Proceedings of the National Academy of Sciences ...

Valves for tiny particles

Newly developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine.

Artificial enzyme can activate a gene switch

Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene ...

Scientists develop 3-D scanner for insects

A scanner developed jointly at TU Darmstadt and Darmstadt University of Applied Sciences enables automated digital archiving of preserved insects—in high-resolution and in 3-D. The scientists have published this new and ...

Lessons from Cape Town's water shortage

South Africa has always been a country with problems of water scarcity. The ominous Day Zero narrative in Cape Town has brought water security into our daily lives and has made us pay closer attention to issues of water demand ...
