AlphaFold 2 is here: what’s behind the structure prediction miracle
Nature has now released that AlphaFold 2 paper , after eight long months of waiting. The main text reports more or less what we have known for nearly a year, with some added tidbits, although it is accompanied by a painstaking description of the architecture in the supplementary information . Perhaps more importantly…

Team from ETH Zurich make high quality quantum swap gate using a geometric phase
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.

Graph Networks for Materials Exploration
We share the discovery of 2.2 million new crystals – equivalent to nearly 800 years’ worth of knowledge. We introduce Graph Networks for Materials Exploration (GNoME), our new deep learning tool that dramatically increases the speed and efficiency of discovery by predicting the stability of new materials.

Study identifies reasons for soaring nuclear plant cost overruns in the U.S.
MIT researchers have analyzed the causes of many cost overruns on new nuclear power plants in the U.S., which have soared in the past 50 years. The findings may help designers of new plants build in resilience to prevent such added costs.

Quench of LHC inner triplet magnet causes a small leak with major consequences
At 1.00 a.m. + 17 seconds on Monday, 17 July, the LHC beams were dumped after only 9 minutes in collision due to a radiofrequency interlock caused by an electrical perturbation. Approximately 300 milliseconds after the beams were cleanly dumped, several superconducting magnets around the LHC quenched – i.e. they lost…

Ozone hole goes large again
Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil.
