The ascension of Cardinal Robert Francis Prevost to the Papacy marks an extraordinary moment for American leadership on the world scene at a time when President Trump has transformed the reputation of the country abroad and fueled the distrust among the longtime allies.But while two Americans now sit in positions of a huge global influence, Pope Leo XIV can offer the world a different vision of the US values ​​from the first approach of Mr. Trump's America, who has performed through rigid rates, imperialist reflections and vast cuts to foreign aid.When it was presented in the world, the new Pope - who speaks five languages ​​and is a naturalized citizen of Peru - underlined his pluralistic background, making it speak in Italian (which represents his new electoral college) and Spanish (...

On a frigid day in early January, as she worked in her office in the Boston suburb of Billerica, Mass., Siyu Huang received a two-word text message.“Spinning wheels,” it said. Attached was a short video clip showing a car on rollers in an indoor testing center.To the untrained eye there was nothing remarkable in the video. The car could have been getting its emissions tested at a Connecticut auto repair shop (except it had no tailpipe). But to Ms. Huang, the chief executive of Factorial Energy, the video was a milestone in a quest that had already occupied a decade of her life.Ms. Huang, her husband, Alex Yu, and their employees at Factorial had been working on a new kind of electric vehicle battery, known as solid state, that could turn the auto industry on its head in a few years — if a ...

The roads looked like Gaza. Houses reduced to rubble, walls cut by bullet holes, roads torn by Bulldozer. The neighborhood after the neighborhood was deserted.But this was not Gaza, a territory devastated by the war between Israel and the Hamas militant group, where tens of thousands have been killed and hunger chases the population. It was occupied, another Palestinian territory in which the Israeli army unexpected control in the wider repression of the militancy there in a generation.The outlines of the new offensive were taking place during a recent visit of the New York Times journalists in the city of Jenin, among the densely populated neighborhoods that have been eliminated since an operation started in January. In one of those areas, over 10,000 people lived until recently. Now, it ...

Donald Trump is the face of these cuts, but the cruelty of his administration is not the only story. After jumping upwards in the 2000s, global health donations have grown very slowly in 2010. Filantropy culture has also changed in some way, with the age of the pledge to give - in which hundreds of richest people in the world have promised to give more than half of their great fortunes to charity - giving first to the starting movement called effective altruism and then to a new era of extremely wealth. from altruism that from grandeur. After the divorce of the Gates in 2021, Melinda eventually left the Foundation to establish his philanthropy; Warren Buffett, a longtime supporter, recently announced his plans to leave most of his remaining fortune in the hands of a charity trust that his ...

Now that the white smoke is finally floated by the fireplace above the Sistine chapel to report that a new pope has been chosen, there will still be a short wait before the identity of the next pontiff becomes clear.Based on what happened when Pope Francis was elected in 2013, it probably takes at least an hour before the designated cardinal appears on a balcony of the Basilica of San Pietro to announce, in Latin, "Annunio Vobis Gaudium Magnum: Habemus Papam" - "I announce a great joy: we have a Pope."The cardinal (for this reason, Cardinal Dominique Mamberti of France is therefore announced the identity of the chosen Pope and the name he will adopt as a pontiff. The last time, Francis came out on the balcony about 10 minutes after the announcement of his identity.(If Cardinal Mamberti wer...

Openi said last Wednesday that he had hired Fidji Simo, CEO of Instacart, to take on a new role that manages the teams of activities and operations of the artificial intelligence company.In a blog post, Sam Altman, CEO of Openai, said he would remain responsible as head of the company. But the appointment of Mrs. Simo as CEO of applications would have freed him to concentrate on other parts of the organization, including research, computer and security systems, he said."We have become a global product company that serves hundreds of millions of users all over the world and growing very quickly," Altman said in the blog post. He added that Openai had also become a "infrastructure company" which provided artificial intelligence tools on a large scale."Each of these is a huge effort that coul...

At the beginning of the 2000s, a coronavirus that infects bats jumped into procione dogs and other wild mammals in south -western China. Some of those animals were sold in the markets, where the Coronavirus jumped again, in humans. The result was Pandemia Sars, which spread in 33 countries and caused 774 lives. A few months, scientists discovered the crownavirus in mammals known as Palm Wests sold in a market in the center of the epidemic.In a study published on Wednesday, a team of researchers compared Sars' evolutionary history with that of Covid 17 years later. The researchers analyzed the genomes of the two coronavirus who caused the pandemics, together with 248 coronavirus related to bats and other mammals.Jonathan Pekar, an evolutionary virologist of the University of Edinburgh a...

Guesses about who the next Roman Catholic pope will be often prove inaccurate. Before the selection of Pope Francis in 2013, many bookmakers had not even counted him among the front-runners.This time, predictions are further complicated, because Francis made many appointments in a relatively short period during his tenure, diversifying the College of Cardinals and making it harder to identify movements and factions within the group.Still, discussion of potential names began long ago behind the Vatican’s walls and beyond. As the cardinals began meeting in Rome after Pope Francis’ funeral, papal watchers scrutinized snippets of statements emerging from their discussions, trying to discern whether the electors were leaning toward a candidate who would build on Francis’ agenda or one who would...
