New technology gives intricate 3D scans of insects

Insects in incredible detail; climate change and the law; new missions to Venus; masks with sensors that can detect SARS-Cov2

The Natural History Museum in London holds a massive collection of insects. It asked researchers at the Diamond light source, a facility near Oxford, to develop a high throughput X-ray microscope to take 3D scans of them all. Roland Pease has been to see the new technology in action.

Many people seeking compensation for the impacts of climate change are turning to the law courts. Successes so far have been few. Oxford University’s Friederike Otto, who specialises in connecting weather extremes to the greenhouse effect, has just published a paper looking at the challenge in bringing successful climate lawsuits. 

Spacecraft will be returning to Venus in the next decade with the recent approval of two NASA missions to the planet, and one from the European Space Agency, ESA. Philippa Mason of Imperial College is a planetary geologist on that mission, Envision. She plans to use radar to peer through that dense and interesting atmosphere to follow up evidence of volcanic activity and tectonics on the surface beneath.  

A few years ago synthetic biologist Jim Collins of Harvard found a way to spill the contents of biological cells onto … basically … blotting paper, in a way that meant by just adding water, all the biochemical circuitry could be brought back to life. With a bit of genetic engineering, it could be turned into a sensor to detect Ebola and Nipah viruses. His team have kept developing the idea, and this week they report success in a smart face mask that can detect SARS-CoV-2 in your breath.
