Genetic 'hitchhikers' can be directed using CRISPR

In a new study, North Carolina State University researchers characterize a range of molecular tools to rewrite—not just edit—large chunks of an organism's DNA, based on CRISPR-Cas systems associated with selfish genetic ...

Force firms to reveal their impact on nature: major businesses

Businesses must be compelled to reveal their impact on nature, more than 300 firms said in an open letter to world leaders published on Wednesday ahead of crunch United Nations negotiations to halt catastrophic biodiversity ...

Detailed insight into friction: How objects start to slide

Chemists and physicists at the University of Amsterdam shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how ...

Health groups call for fossil fuel non-proliferation treaty

Around 200 health organizations and more than 1,400 health professionals on Wednesday called for governments to establish a binding international treaty on phasing out fossil fuels, which they said pose "a grave and escalating ...

Making mini-magnets that induce a quantum anomalous Hall effect

A new device has been fabricated that can demonstrate the quantum anomalous Hall effect, in which tiny, discrete voltage steps are generated by an external magnetic field. This work may enable extremely low-power electronics, ...

Simulating 3D-AFM images for systems not in equilibrium

Researchers at Kanazawa University report in the Journal of Physical Chemistry Letters how to simulate 3D atomic force microscopy images of out-of-equilibrium systems involving biomolecules. The approach makes use of a celebrated ...
