nature Magazine – June 15, 2023 issue: In this week’s issue, Abhinav Kandala and his colleagues show that it is still possible for a quantum computer to outperform a classical computer, by mitigating, rather  than correcting, the errors. 

DeepMind AI creates algorithms that sort data faster than those built by people

The technology developed by DeepMind that plays Go and chess can also help to write code.

An artificial intelligence (AI) system based on Google DeepMind’s AlphaZero AI created algorithms that, when translated into the standard programming language C++, can sort data up to three times as fast as human-generated versions.

“We were a bit shocked,” said Daniel Mankowitz, a computer scientist at DeepMind who led the work. “We didn’t believe it at first.”

Ukraine dam collapse: what scientists are watching

Extensive flooding could have severe consequences for farming, health and the environment.

The 66-year-old Kakhovka dam on the Dnieper River in south Ukraine collapsed on the morning of 6 June after a suspected explosion, triggering a catastrophic humanitarian and environmental crisis.

nature Magazine – June 8, 2023 issue:  Coral reef fishes, such as the blenny Ecsenius stictus pictured on the cover, are diverse, abundant and grow quickly. In this week’s issue, Alexandre Siqueira and his colleagues investigate the evolutionary history of these fishes to find out how growth has shaped life on coral reefs. 

Camera that could fit on a penny captures vivid colour photos

Optimized phase mask of five-millimetre diameter fabricated using a nanofabrication approach.

A ‘meta-lens’ and corrective algorithms allow a tiny device to produce high-resolution images.

A computational-imaging technique paves the way for ultra-small cameras that could be used in various portable devices.

These hardy ants build their own landmarks in the desert

Tunisian desert ant Cataglyphis fortis.

Ants living on the sprawling salt pans of Tunisia use DIY markers to find their way home.

The desert ant Cataglyphis fortis lives in Tunisia’s arid salt flats, and can travel more than a kilometre from its underground nest in search of food. Now scientists have found that these ants build tall hills on top of their nests that help the insects to find their way home across the vast, featureless landscape1.
