French President Emmanuel Macron gave an extraordinary interview to The Economist in which he declared, "What we are currently experiencing is the brain death of NATO." The cause of this malaise, he said, is the United States abandoning Europe. He doubts the viability of NATO's mutual-defense clause, saying NATO "only works if the guarantor of last resort functions as such. I'd argue that we shou
Redan 1982, i Murhopparen, formulerade den västtyske författaren Peter Schneider ett problem som lever kvar ännu 30 år efter att muren föll, och 29 år efter att det forna Östtyskland och Västtyskland återförenades. Schneider, vars korta roman handlade om människor som flydde över muren, skrev: "Att riva ner muren i våra tankar kommer att ta längre tid än något rivningsföretag behöver för den synli
From reporting election results to issuing weather forecasts, maps offer a powerful, accessible and visually appealing way to convey complex information. But as a researcher focusing on data visualisation, I'm aware that even the most beautiful maps can introduce some degree of misrepresentation.
A global coalition of 11,000 scientists has come up with a plan for dealing with the climate emergency. Most of these are things scientists have been saying for a while: decarbonise the economy, eliminate pollutants, restore ecosystems and reforest, and reduce meat consumption. However, the last action point is somewhat more controversial. It calls for stabilising the global population.
Det finns flera fördelar med ultraljudsbehandling mot prostatcancer, menar forskare vid Akademiska sjukhuset i Uppsala. En är precisionen, ultraljud riktas enbart mot själva tumörområdet inne i prostata. Målgruppen är män med prostatacancer utan metastaser. Akademiska blir första sjukhuset i Sverige med att införa högintensivt fokuserat ultraljud, HIFU, som potentiellt botande behandling mot pros
"Uitwaaien" is a popular activity around Amsterdam—one believed to have important psychological benefits. Photograph by John Loo / Flickr Recently I was in San Francisco, a city known for its tech companies, steep hills, and fierce winds. Each day I'd run around the neighborhood and up through the park, ending with a spectacular view of the Golden Gate Bridge. Back in my AirBnB, I'd feel energize

It took a little more than a decade for the University of Chicago to reinvent itself , going from a well-regarded but largely regional school to an extremely selective university with national prestige. In 2006, the Hyde Park university admitted more than a third of its freshman applicants. That rate has plummeted so drastically in the years since—to a record-low 5.9 percent in the most recent ap
Anyone who's ever seen a CSI episode, read an Agatha Christie novel, or white-knuckled their way through a thriller in a movie theater understands that the key element of such stories is suspense. At the most basic level, there's a crime, no one knows whodunit, and someone has to crack the case. It's the suspense that keeps readers and watchers engaged, searching for the clinching evidence. This
The year ahead will be no ordinary year. One year from now, barring historically unusual scenarios, we will know the results of the 2020 election, and who will be the next president of the United States. But the election is not all that's at stake. The next 12 months will test the U.S. Constitution and determine the future of the American experiment. Will we manage to keep the republic entrusted
On The Tonight Show last week, the singer FKA Twigs made use of a new kind of stage. She began singing her ballad "Cellophane" while sitting on top of a piano. Her pose was a crumpled one, with the glorious ruffles of her gown—medieval in shape, but more Lil Nas X–like with its bandana-print pattern—splayed about her. Midway through the song, Twigs got up and walked down a catwalk-like extension

When Naya arrived in Belgium in January 2018, she was the first wolf to be tracked in the country for at least 100 years. She'd been followed with a radio collar since she was a cub, so scientists knew when she left her family pack in eastern Germany to start a new life across the border. They also knew when she met another interloper, the male wolf, August, in August 2018.
The world of work is fast changing. As life expectancy lengthens and labour markets shift, our working lives have become more complicated. The old expectations about how we work have become unsustainable—not least the expectation that we religiously travel to and from a fixed location ten times a week during rush hour, with all the knock-on effects that this has for carbon emissions.

Engineers have developed a robot designed to extend a chain-like appendage flexible enough to twist and turn in any necessary configuration, yet rigid enough to support heavy loads or apply torque to assemble parts in tight spaces. When the task is complete, the robot can retract the appendage and extend it again, at a different length and shape, to suit the next task.
Scientists say a failure of Australian management means excessive amounts of harmful chemicals — many now banned in countries such as the EU, USA and Canada — are damaging the country's waterways and the Great Barrier Reef.
All cells in the body contain the same genetic material. The difference between cells therefore depends solely on which genes are expressed or 'turned on'. Now, researchers have gained new insights into how genes are turned on and off and how the cells "forget their past" while developing into a specific cell in the body. This new knowledge will be crucial for stem cell therapy and potentially t
