The China Manned Space Agency has tentatively approved more than 1,000 experiments for the Tiangong space station, several of which have already been launched. China launched the core of the space station in April and sent three astronauts up in June. The station is likely to be completed in late 2022.
AlphaFold has predicted the structure of nearly the entire human proteome (the full complement of proteins expressed by an organism) and made it available through a public database. The deep-learning neural network, developed by Google’s artificial-intelligence firm DeepMind, predicts the 3D structures of proteins from their amino-acid sequences. AlphaFold has also predicted almost complete proteomes for other organisms, ranging from mice and maize (corn) to the malaria parasite. The more than 350,000 protein structures vary in their accuracy. But researchers say the resource — which is set to grow to 130 million structures by the end of the year — has the potential to revolutionize the life sciences.
Features & opinion
An estimated 8% of scientists who participated in an anonymous survey of research practices at Dutch universities confessed to falsifying and/or fabricating data at least once between 2017 and 2020. More than 10% of medical and life-science researchers admitted to committing this type of fraud, the survey found.

Venus’ flower baskets (Euplectella aspergillum) are marine sponges that live at the bottom of the Pacific Ocean. These sponges have an unusual glass skeleton that helps them gather food, and even appears to control ocean currents.
Today, Leif Penguinson is tucked among the spectacular volcanic tuff of Wheeler Geologic Area in Colorado. Can you find the penguin? Thanks to Briefing reader Donna Singleton for suggesting Leif’s itinerary.
The answer will be in Monday’s e-mail, all thanks to Briefing photo editor and penguin wrangler Tom Houghton.This newsletter is always evolving — tell us what you think! Please send your feedback to firstname.lastname@example.org.
