This exhibition celebrates the addition of nine masterpieces to the French national collections – six paintings, two sculptures and a sketchbook – via the country’s gifts-in-lieu scheme, which was introduced on 31 December 1968, allowing inheritance tax to be paid in kind. This unique acquisition mode is key to the very identity of Musée Picasso, which was founded in 1979 specifically to house the donation made by Pablo Picasso under this system.
Pablo Ruiz Picasso was a Spanish painter, sculptor, printmaker, ceramicist and theatre designer who spent most of his adult life in France.
On this week’s show: How physicists are using quantum sensors to suss out dark matter, how rabies thwarts canine vaccination campaigns, and a kickoff for our new series with authors of books on food, land management, and nutrition science
Dark matter hunters have turned to quantum sensors to find elusive subatomic particles that may exist outside physicists’ standard model. Adrian Cho, a staff writer for Science, joins host Sarah Crespi to give a tour of the latest dark matter particle candidates—and the traps that physicists are setting for them.
Next, we hear from Katie Hampson, a professor in the Institute of Biodiversity, Animal Health & Comparative Medicine at the University of Glasgow, about her work contact tracing rabies in Tanzania. Her group was able to track rabies in a population of 50,000 dogs over 14 years. The massive study gives new insight into how to stop a virus that circulates at superlow levels but keeps popping up, despite vaccine campaigns.
Finally, we launch our 2022 books series on food and agriculture. In six interviews, which will be released monthly for the rest of the year, host and science journalist Angela Saini will speak to authors of recent books on topics from Indigenous land management to foods that are going extinct. This month, Angela talks with Lenore Newman, director of the Food and Agriculture Institute at the University of the Fraser Valley, who helped select the books for the series.
This week The World Economic Forum are highlighting 4 top stories – how Ukraine’s economy is predicted to shrink, a new solar energy storage chip, the reason behind sinking cities and a transformative toilet design.
Timeline: 00:16 Ukraine economy to shrink 01:34 Solar energy storage chip 03:02 Sinking cities 04:25 Transformative toilet
We hear from Beijing about the city’s fears of a Shanghai-style lockdown and ask how the country’s “zero-Covid” policy affects the ruling Chinese Communist Party. Plus: the escalation of Hungary’s rule-of-law spat with the EU, the latest TV news and an interview with South Korea’s only astronaut.
So far, the invasion of Ukraine has been a disaster for Russia’s armed forces. About 15,000 troops have been killed in two months of fighting, according to Britain’s government. At least 1,600 armoured vehicles have been destroyed, along with dozens of aircraft and the flagship of the Black Sea fleet.
The cover shows an artist’s impression of the pterosaur Tupandactylus imperator. Although feathered pterosaurs have been reported, these claims have been controversial and it has not been clear whether these leathery-winged flying reptiles had feathers of different colours like modern-day birds.
In this week’s issue, Aude Cincotta and her colleagues present evidence that not only did pterosaurs have feathers but that the feathers probably had varied coloration. The researchers analysed a partial skull of Tupandactylus, found in Brazil and dated to around 113 million years ago. They identified two types of feather along the base of the crest, one of which featured branched structures very similar to modern feathers. They also found pigment-producing organelles in both types of feather and the skin on the head crest. The team suggests that these coloured feathers would have been used in visual communication and that their presence in Tupandactylus indicates the ability to manipulate feather colour stretches back farther than was previously realized.
