The bitcoin boom spawned new billionaires and videos of beach parties and Lamborghinis. The crypto crash brought devastation for small investors and bankruptcy for many companies. Blockchain technology underpins crypto and has been hailed as a world-changing innovation, but does it have any use beyond creating speculative financial instruments? AFP asked crypto critic Stephen Diehl, author of recently published "Popping the Crypto Bubble", to run the rule over some of the most popular claims made for blockchain technology.

Forced to start picking grapes much earlier than normal because of torrid temperatures, winemakers across France are worrying that grape quality will suffer from the climate-induced stress. The exceptionally dry conditions spread from the rugged hills of Herault along the Mediterranean, where picking is already underway, to the normally verdant Alsace in the northeast. Waves of extreme heat this summer accelerated grape maturation, meaning harvests had to begin one to three weeks early or more -- in Languedoc-Roussillon, some growers even started in late July. "We were all a bit surprised, the...

The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, a ski resort said Thursday. Following a dry winter, the summer heatwaves hitting Europe have been catastrophic for the Alpine glaciers, which have been melting at an accelerated rate. The pass between Scex Rouge and Tsanfleuron has been iced over since at least the Roman era. But as both glaciers have retreated, the bare rock of the ridge between the two is beginning to emerge -- and will be completely ice-free before the summer is out. "The pass will be entirely in ...

The drought that has left a large part of Europe's soils dry since the beginning of the summer serves as a reminder that water is a precious and exhaustible commodity. The restrictions imposed on farmers lead to serious considerations about the food of tomorrow. One solution could come from West African countries, which, for thousands of years, have been cultivating a cereal that needs almost no water to grow. That grain is fonio. It's not wheat, it's not barley, and it's not quinoa either. But, it looks quite similar to these grains. Available in white and black varieties, although the latter...

By 2029, the meat substitute market is expected to grow by more than 11% to $12 billion. And hardly a day goes by without the food industry coming up with a new animal-protein-free alternative. However, the success of this market may not be quite what you think... Plant-based alternatives are still far from winning over all consumers Consumers born after World War II and up to 1965 -- those typically referred to as "boomers" -- are not the category most attracted to this type of food. Gen Z, those born in the late 1990s, but also Millennials, consumers born between the early 1980s and mid-1990...

US teens have left Facebook in droves over the past seven years, preferring to spend time at video-sharing venues YouTube and TikTok, according to a Pew Research Center survey data out Wednesday. TikTok has "emerged as a top social media platform for US teens" while Google-run YouTube "stands out as the most common platform used by teens," the report's authors wrote. Pew's data comes as Facebook-owner Meta is in a battle with TikTok for social media primacy, trying to keep the maximum number of users as part of its multi-billion dollar ad-driven business. The report said some 95 percent of the...

Vienna, a city known for its Christmas markets and its New Year concert, is cutting back on public lighting in the face of soaring energy prices. "There will be no Christmas illuminations this year on the Ring," the famous boulevard that encircles the center of the Austrian capital, city spokeswoman Roberta Kraft told AFP. And the lights at the Christmas market in the square in front of the city hall would only be switched on at night and not at dusk, as in previous years, "which is to say about an hour later, on average, every day," she said. The city authorities said they had not calculated ...

Artist and musician Zach Katz virtually transforms the streets of the world's major cities in order to show how the space could be made more hospitable to pedestrians. Every day, he posts new creations on his Twitter account and, in the space of a few weeks, has become something of a star among internet users, city planners and politicians. How do we imagine the downtown zones of the future?

Here, fountains, green space, rails or even roads res...

The menu at The Canteen in southwest England doesn't just let diners know how much a dish costs. They can also check its carbon footprint. The carrot and beetroot pakora with yoghurt sauce is responsible for just 16 grams of CO2 emissions. The aubergines with a miso and harissa sauce with tabbouleh and Zaatar toast caused 675 grams of carbon dioxide. As customers weigh their options, the menu at the vegetarian restaurant in Bristol includes a comparison with a dish that it does not serve: the emissions from a UK-produced hamburger. "Three kilos for a burger, wow! I can't believe it," exclaimed...

Marking a new departure in the era of environmentally conscious air travel, Lufthansa is making carbon offsetting easily available to travelers at the time of choosing and booking their tickets. Indeed, the German carrier has decided to make it a full-fledged fare category. Passengers can offset the carbon footprint of a flight by donating to reforestation projects. They can invest in the deployment of biofuels, calculate precisely the amount of carbon dioxide generated by a particular journey, and convert the amount into donations for environmental programs. For several years now, airlines ha...
