Astronomers using the James Webb Space Telescope (JWST) have produced the clearest look yet at how Uranus’ upper atmosphere behaves, after tracking the planet for about 15 hours, nearly a full Uranian rotation, to capture how its auroras and charged particles change with time and altitude. The observations focused on Uranus’ ionosphere, the high-altitude region where solar-driven particles interact with the planet’s magnetic environment. Using JWST’s Near-Infrared Spectrograph (NIRSpec), the team mapped the temperature and density of ions through the upper atmosphere, creating what researchers described as the first three-dimensional view of key parts of the system. Uranus has long…

Nvidia reported another blowout quarter, extending a run of results that has helped make the chipmaker a key barometer for investor confidence in the artificial intelligence boom. For the fiscal fourth quarter ended Jan. 25, 2026, the Santa Clara, California-based company said revenue rose to $68.1 billion, up 20% from the prior quarter and up 73% from a year earlier. Profit growth was even sharper. Net income climbed to $42.96 billion, and GAAP earnings per diluted share were $1.76, nearly doubling from the year-ago period, according to the company’s earnings release. The latest report was closely watched after a period…

Nicolás Maduro’s U.S. defense team says the American government is blocking the Venezuelan state from paying legal bills that, under Venezuelan practice, would typically be covered for a former head of state facing foreign prosecution. In a message filed into the public record of the Manhattan federal case, attorney Barry Pollack told the judge that the U.S. Treasury Department’s sanctions office first granted permission for the payments and then withdrew it within hours, without an explanation. Pollack’s account centers on the Office of Foreign Assets Control (OFAC), which administers U.S. sanctions. He said OFAC approved a license on January 9…

Gucci has drawn online criticism after publishing a set of promotional images labeled “Created with AI” to advertise its upcoming Primavera presentation during Milan Fashion Week. The posts circulated across the brand’s social platforms and were quickly reposted by users who argued the visuals looked inconsistent with a luxury house that markets itself around craftsmanship and creative production. The campaign points to the show’s timing and format, listing “February 27” and “2 p.m. CET” in the promotional copy shared online. The show is expected to stream, adding to its visibility beyond the Milan runway calendar. Much of the criticism focused…

When Mikaela Shiffrin crossed the line in Cortina d’Ampezzo, Italy, the reaction that followed did not match the scale of the result. Her final run left her 1.5 seconds ahead of the rest of the field, a decisive margin in a discipline where medals often hinge on tiny fractions. Yet she did not leap, shout, or collapse. She stopped, stood still, and looked back up the slope, poles hanging at her sides as the crowd around her erupted. Only after a beat that seemed to stretch did she drop into a crouch and stare at the snow. The scene carried…

A group of three Senate Democrats is introducing legislation that would require the federal government to return an estimated $175 billion in tariff revenue collected under tariff orders that the U.S. Supreme Court recently ruled unlawful. The proposal comes from Sens. Ron Wyden of Oregon, Ed Markey of Massachusetts, and Jeanne Shaheen of New Hampshire. Their bill would direct U.S. Customs and Border Protection to issue refunds within 180 days and pay interest on the returned funds. The measure would also prioritize reimbursements for small businesses, while encouraging importers, wholesalers, and larger companies to pass the refunded money through to…

Barclays has sharply reduced its peak sales estimate for Novo Nordisk’s next-generation obesity treatment CagriSema, cutting the forecast to US$2 billion from US$12 billion, according to a Reuters report published on February 24, 2026. The revision represents a reduction of more than 80% and reflects a rapid reassessment of the drug’s commercial prospects after new late-stage trial data. The downgrade followed results released by Novo Nordisk a day earlier, which analysts viewed as a setback in the company’s effort to defend its position in the fast-growing obesity drug market. CagriSema had been widely seen as a potential follow-on product to…

Delta Air Lines has issued a travel waiver for customers flying to parts of western Mexico after violent unrest disrupted air travel following the killing of a major cartel leader. The waiver remains in effect as security concerns continue to affect operations in and around Jalisco state. According to CBS Atlanta, the airline said the disruption followed the death of Nemesio Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG). The report said cartel members responded by blocking roads and setting vehicles on fire, contributing to widespread violence in the region. Delta’s advisory states…

The U.S. Supreme Court has announced that it will hear a significant legal challenge brought by major oil and gas companies seeking to block climate change-related lawsuits filed by state and local governments across the country. The case, arising from Boulder, Colorado, involves claims that fossil fuel firms misled the public about the environmental impact of their products and seeks financial compensation for climate-related damages. In agreeing to take up the case, the Supreme Court will review an appeal from ExxonMobil and Suncor Energy following a decision last year by the Colorado Supreme Court that allowed Boulder and Boulder County…

The European Union’s attempt to adopt its 20th sanctions package against Russia stalled on February 23, 2026, when Hungary objected to the measures at an EU foreign ministers’ meeting in Brussels. The package, designed to tighten economic pressure on Moscow ahead of the fourth anniversary of Russia’s full-scale invasion of Ukraine, could not secure the unanimous support required from all 27 member states. EU Foreign Policy Chief Kaja Kallas confirmed that there was no agreement on the sanctions, calling the outcome “a setback” and underscoring that the bloc had hoped to finalize the measures in time for the anniversary of…
