    Care About Food Waste? In Massachusetts, You Can Be a Compost Consultant.

    America has a food waste problem: Rotten tomatoes and pizza boxes end up in trash dumps and produce a potent planet-heating gas called methane.Massachusetts has a fix: A state regulation requires businesses to keep food out of dumpsters. To help them comply, the state offers a carrot, in the form of a chatty, practical, 63-year-old hand-holding food-waste-reduction consultant named Heather Billings.Which is how, on a frigid Wednesday morning, Ms. Billings found herself poking around the narrow kitchen of the Port Tavern, a sports bar in Newburyport, Mass.An owner of the Port Tavern, Abbie Hannan, left, invited Ms. Billings to look at how the restaurant managed its waste.She quickly spotted a very solvable problem at the prep cook’s station: a 23-gallon trash can into which went tomato tops and other food scraps.Then came the dumpster inspection. Could anything in there go to compost?Ms. Billings, a consultant contracted by the state government, took notes, snapped pictures and peered behind the bar to assess where the lemon wedges and plastic olive skewers ended up.She had some easy fixes for Port Tavern’s co-owner Abbie Hannan. She proposed inexpensive, four-gallon plastic buckets to nest inside the bigger trash bins to collect food scraps. She connected Ms. Hannan to compost haulers and a charity that could pick up leftover edible food.Tell Us About Solutions Where You Live

    They’re in Hot Water in Idaho. Here’s Why That’s a Good Thing.

    50 States, 50 FixesThey’re in Hot Water in Idaho. Here’s Why That’s a Good Thing.Nearly 500 buildings in the state capital get their heat from a clean, renewable source located deep in the ground.Kirkham Hot Springs in Boise National Forest.It’s pretty easy to get into hot water in Boise. After all, it’s in Idaho, a state filled with hundreds of hot springs.The city has tapped into that naturally hot water to create the largest municipally run geothermal system in the country.Nearly 500 Boise businesses, government buildings and homes — as well as hospital and university buildings, City Hall and a Y.M.C.A. — are warmed by heat drawn directly from hot water reservoirs, or aquifers, below ground. The Idaho Statehouse, in Boise, is the only one in the United States to use geothermal heat. The heat even warms some sidewalks in the winter, to melt the snow, and raises the temperature in hot tubs.50 States, 50 Fixes is a series about local solutions to environmental problems. More to come this year.Renewable, reliable and relatively free of pollution, geothermal heating is possible in Boise because of fault lines that expose groundwater to hot rocks, heating water to around 170 degrees Fahrenheit, or about 77 degrees Celsius. The water is drawn from wells in nearby foothills into a closed-loop network of pipes that reach into buildings, before going back to the aquifer to be heated again.Tell Us About Solutions Where You Live

    Texas Prosecutors Will No Longer Pursue Death Penalty in El Paso Shooting

    The gunman, who killed 23 people at a Walmart in 2019, was previously sentenced to 90 consecutive life terms after pleading guilty to federal hate crimes.Texas prosecutors will no longer seek the death penalty against the gunman who killed 23 people in a mass shooting at an El Paso Walmart six years ago, the local district attorney announced on Tuesday.The gunman, a self-described white nationalist, had previously been sentenced to 90 consecutive life terms after pleading guilty to federal hate crimes in the attack, one of the deadliest on Latinos in U.S. history. At the time, federal prosecutors also said they would not seek the death penalty.On Tuesday, the El Paso district attorney said his office had changed course after speaking with the families of the victims.“It was very clear as we met with the families, one by one, that there is a strong and overwhelming consensus that just wanted this case over with, that wanted finality in the court process,” said the district attorney, James Montoya, a Democrat.In exchange, the shooter, Patrick Crusius, is expected to plead guilty to capital murder and be sentenced to life in prison without the possibility of parole, Mr. Montoya said. Mr. Crusius will also waive his right to any potential appeals as part of the plea agreement.Mr. Montoya is the fourth prosecutor to have been assigned to the state case. He promised during his campaign last year to seek the death penalty, and said on Tuesday that he still believed the shooter deserved it.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    U.S. Adds Export Restrictions to More Chinese Tech Firms Over Security Concerns

    The additions included companies that are customers of Intel and Nvidia, and one firm that was the focus of a New York Times investigation last year.The Trump administration on Tuesday added 80 companies and organizations to a list of companies that are barred from buying American technology and other exports because of national security concerns.The move, which targeted primarily Chinese firms, cracks down on companies that have been big buyers of American chips from Nvidia, Intel and AMD. It also closed loopholes that Trump administration officials have long criticized as allowing Chinese firms to continue to advance technologically despite U.S. restrictions.One company added to the list, Nettrix Information Industry, was the focus of a 2024 investigation by The New York Times that showed how some Chinese executives had bypassed U.S. restrictions aimed at cutting China off from advanced chips to make artificial intelligence.Nettrix, one of China’s largest makers of computer servers that are used to produce artificial intelligence, was started by a group of former executives from Sugon, a firm that provided advanced computing to the Chinese military and built a system the government used to surveil persecuted minorities in the western Xinjiang region.In 2019, the United States added Sugon to its “entity list,” restricting exports over national security concerns. The Times investigation found that, six months later, the executives formed Nettrix, using Sugon’s technology and inheriting some of its customers. Times reporters also found that Nettrix’s owners shared a complex in eastern China with Sugon and other related companies.After Sugon was singled out and restricted by the United States, its longtime partners — Nvidia, Intel and Microsoft — quickly formed ties with Nettrix, the investigation found.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    After the Signal Leak, How Well Do You Know Your Own Group Chats?

    A journalist’s inclusion in a national security discussion served as a reminder that you might not know every number in the chat — and that could be a big problem.Hey, are you sure you want to send that to your group chat? Like, one thousand percent sure?Just checking. Because it’s been a strange week in the history of the group chat, those seemingly intimate text conversations that ping back and forth among friends and family members and, apparently, national security personnel.On Monday, the editor in chief of The Atlantic, Jeffrey Goldberg, wrote that he had accidentally been added to a group chat on the encrypted messaging app Signal. He followed along as Defense Secretary Pete Hegseth laid out attack plans against Houthi strongholds in Yemen and watched other national security officials post celebratory emoji after the strikes had taken place.As lawmakers on both sides of the aisle condemned the security breach, Americans with their own unruly group chats watched with recognition and disbelief: How had some of the country’s most powerful officials managed to so badly bungle using technology that millions of people rely on every day?“Obviously it’s a very relatable screw-up,” Mr. Goldberg said during an interview with Tim Miller of The Bulwark on Tuesday. “We’ve all sent texts to the wrong people,” he added.Those inadvertent texts, however, don’t typically contain high-stakes national security information that is being shared outside secure government channels.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Trump’s Team Calls Europe ‘Pathetic’ in Leaked Signal Group Chat Messages

    Trump administration officials haven’t kept their disdain for Europe quiet. But the contempt seems to be even louder behind closed doors.Europeans reacted with a mix of exasperation and anger to the publication of parts of a discussion between top-ranking Trump administration officials, carried out on the messaging app Signal. The discussion, about a planned strike on Yemen, was replete with comments that painted Europeans as geopolitical parasites, and was revealed on Monday in The Atlantic, whose editor was inadvertently included in the conversation.“I just hate bailing out the Europeans again,” wrote Vice President JD Vance, asserting that the strikes would benefit Europe far more than the United States.“I fully share your loathing of European freeloading,” Pete Hegseth, the secretary of defense, later replied. “It’s PATHETIC.”The exchange seemed to show real feelings and judgments — that the Europeans are mooching and that any American military action, no matter how clearly in American interests as well, should be somehow paid for by other beneficiaries.A member of the chat identified as “SM,” and believed to be Stephen Miller, a top aide to President Trump, suggested that both Egypt and “Europe” should compensate the United States for the operation. “If Europe doesn’t remunerate, then what? If the US successfully restores freedom of navigation at great cost there needs to be some further economic gain extracted in return,” SM wrote.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Inside A.I.’s Super Bowl: Nvidia Dreams Of A Robot Future

    The robots were everywhere. Some pedaled around like “Star Wars” droids. Others manipulated hospital surgery equipment. They all provided a glimpse of what a future powered by artificial intelligence could look like.Nvidia, the world’s largest maker of artificial intelligence chips, brought the robots together as part of its annual developer conference in San Jose, Calif. The event, formally known as Nvidia GTC, has become the Super Bowl of A.I.The weeklong showcase of robots, large language models (the systems behind A.I.-powered chatbots) and autonomous cars drew a who’s who of industry leaders and more than 25,000 attendees. They were there to learn about the latest A.I. technologies and hear Jensen Huang, Nvidia’s chief executive, speak about A.I.’s future. Here are some photos and videos from the A.I. extravaganza:Loren Elliott for The New York TimesNvidia’s chief executive, Jensen Huang, who has been nicknamed “A.I.

    Trump’s Crypto Venture Introduces a Stablecoin

    World Liberty Financial, the cryptocurrency company started by Donald J. Trump and his sons, announced on Tuesday that it was planning to sell a digital currency called a stablecoin, deepening the president’s financial ties to crypto as his administration relaxes enforcement of the industry.The stablecoin would be known as USD1, the company wrote in a social media post, without revealing when it would go on sale. Stablecoins, a popular form of cryptocurrency, are designed to maintain a constant value of $1, making them useful for many types of crypto transactions.“No games. No gimmicks. Just real stability,” World Liberty Financial posted on its X account.The stablecoin is the fourth digital currency that Mr. Trump and his business partners have marketed to the public over the last year. World Liberty already offers a cryptocurrency called WLFI. This month, World Liberty announced it had sold $550 million of those digital coins. A business entity linked to Mr. Trump receives a 75 percent cut of the sales.Days before his inauguration, Mr. Trump also started selling a so-called memecoin — a type of digital currency based on an online joke or a celebrity mascot. Melania Trump put her own memecoin on the market that same weekend.Mr. Trump has made aggressive forays into the crypto market as his administration eases enforcement of crypto firms and rolls back regulations. His efforts to profit from an industry he oversees amount to an enormous conflict of interest, with virtually no precedent in American history, government ethics experts have said.World Liberty’s stablecoin adds to that messy knot of business conflicts. Congress is considering legislation to regulate stablecoins that could reach Mr. Trump’s desk before the end of the year. In a speech at a crypto conference this month, Mr. Trump called for “simple, common sense rules” for stablecoins, saying they would “expand the dominance of the U.S. dollar.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
