As cases of a new, highly contagious “super flu’” surge across the nation this holiday season, more and more Americans are looking for ways to treat the symptoms, which include everything from fever and chills, to headaches and vomiting. A variant of influenza A H3N2, called subclade K, which is being blamed for an early and severe flu season in the United Kingdom, has hit residents in New York, Rhode Island, Colorado and Louisiana the hardest, according to the Centers for Disease Control and Prevention (CDC). While flu vaccines usually have an efficacy rate of 40% to 60% an early report from the U.K. estimates this “super flu” strain has an efficacy rate of 32% …

Stocks moved slightly lower in midday Friday trading as investors returned from the Christmas holiday. Trading is expected to be light. The S&P 500 index was down 0.1% as of 12:15 p.m. ET, the Dow Jones Industrial Average was down 0.2%, and the Nasdaq composite was down less than 0.1%. Institutional investors are largely closed out of their positions for the year. The S&P 500 has climbed nearly 18% this year, helped by the deregulatory policies of the The President administration as well as investor optimism about the future of artificial intelligence. Gold and silver prices continued to climb, with silver rising more than 7% to $76.88 an ounce. Gold w…

Artificial intelligence is transforming how we cure disease, defend nations, and deliver goods. But the same technology driving this surge of innovation is also testing the limits of the system that supports it. Innovation is moving faster than infrastructure, and our energy strategy has to catch up. It’s time to manage energy as a strategic asset. While AI is fueling demand at historic levels, it also gives us the tools to use power more intelligently, stabilize the grid, and unlock capacity we already have. If we work together, AI can turn today’s energy challenge into tomorrow’s competitive advantage. INNOVATION IS OUTPACING THE GRID AI is reshaping the global …

High-speed rail systems are found all over the globe. Japan’s bullet train began operating in 1964. China will have 31,000 miles (50,000 kilometers) of high-speed track by the end of 2025. The fastest train in Europe goes almost 200 mph (320 kph). Yet high-speed rail remains absent from most of the U.S. Stephen Mattingly, a civil engineering professor at the University of Texas at Arlington, explains why high-speed rail projects in much of the country so often go off track. Dr. Stephen Mattingly discusses the problems that come with implementing high-speed rail in the U.S. The Conversation has collaborated with SciLine to bring you highlights from the d…

A number of airlines are waiving change fees ahead of what is expected to be a major winter storm forecast to hit the Northeast on Friday afternoon, affecting millions of people traveling after Christmas, during one of the busiest times of the year. A winter storm warning from the National Weather Service (NWS) is in effect for New York City, New Jersey, and Connecticut from Friday afternoon through Saturday, for up to 9 inches of snow and freezing temperatures, creating the potential hazardous travel conditions, flight delays, and cancellations. 1-6 inches of snow is expected from northeastern Pennsylvania up into New England; while freezing rain and sleet, are expec…

Nvidia has agreed to license technology from AI startup Groq for use in some of its artificial intelligence chips, marking the chipmaker’s largest deal and underscoring its push to strengthen competitiveness amid surging demand. Here is a list of multi-billion-dollar AI, cloud and chip deals signed recently: OPENAI DEALS Amazon and OpenAI Amazon is considering an investment of around $10 billion in OpenAI, though talks remain “very fluid,” according to a source who requested anonymity due to the private nature of their talks. Disney and OpenAI Walt Disney to invest $1 billion in OpenAI and will let the ChatGPT-parent use characters from Star Wars, P…

AI is no longer the future of healthcare; it’s already reshaping how patients are diagnosed and treated. Some of the most interesting developments involve systems that sense and respond to human emotion. Cedars-Sinai’s Connect platform, for example, adapts care based on patient sentiment; CompanionMx interprets vocal and facial cues to detect anxiety; and Feel Therapeutics uses emotion-sensing wearables to tailor interventions in real time. At the same time, clinical tools are evolving. Hospitals are pairing large language models (LLMs) with AI note-taking apps such as Nabla and Heidi, which can listen, summarize, and respond to the nuances of doctor–patient conversat…

If you’re embarrassed every time you have to hand over that Gmail address you came up with in 2006, you’re in luck. Google is finally allowing users to change their Gmail username without creating an entirely new account. The update will allow you to edit your email address to any that isn’t taken. Until now, Google only offered the option to create an alternate email and forward your mail to a new @gmail.com address. But, if you wanted any of your documents, pictures, or other media, then it required you to transfer all the data over—a process that is far from smooth. Now, Google is offering the ability to keep all of that information, whether you’ve changed y…

For the past three years, AI’s breakout moment has happened almost entirely through text. We type a prompt, get a response, and move to the next task. While this intuitive interaction style turned chatbots into a household tool overnight, it barely scratches the surface of what the most advanced technology of our time can actually do. This disconnect has created a significant gap in how consumers utilize AI. While the underlying models are rapidly becoming multimodal—capable of processing voice, visuals, and video in real time—most consumers are still using them as a search engine. Looking toward 2026, I believe the next wave of adoption won’t be about utility alone, …

A Powerball ticket purchased at a gas station outside Little Rock, Arkansas, won a $1.817 billion jackpot in Wednesday’s Christmas Eve drawing, ending the lottery game’s three-month stretch without a top-prize winner. The winning numbers were 04, 25, 31, 52 and 59, with the Powerball number being 19. The winning ticket was sold at a Murphy USA in Cabot, lottery officials in Arkansas said Thursday. No one answered the phone Thursday at the location, which was closed for Christmas. The community of roughly 27,000 people is 26 miles (42 kilometers) northeast of Little Rock. Final ticket sales pushed the jackpot higher than previous expected, making it the second-largest in…

As 2025 comes to a close, business leaders are inevitably already planning how 2026 will shape up, particularly as the last year proved to be a tumultuous one. The so-called AI boom is still booming, corporate DEI initiatives have shrunk or disappeared altogether, and return-to-office mandates have tightened. No one has a crystal ball to predict emerging technologies, financial headwinds, political hurdles, and market trends for the next year. But that doesn’t mean that companies can sit back—there are steps to take now to help insulate your company against potential turbulence in the coming year, while simultaneously fostering success by focusing on the human aspects…

What’s one thing most Americans likely don’t know? Demand for donor sperm is increasing. Initially established in the 1970s to help men undergoing vasectomies and facing cancer treatments, sperm banks today support people facing a wide range of challenges on their path to pregnancy. Alongside heterosexual couples dealing with infertility issues like azoospermia and young men facing cancer diagnosis, single mothers by choice, and same-sex couples are frequently turning to sperm banks in hopes of building their family. With approximately 1,500 sperm donors serving the entire United States, a new sperm bank, Premier Sperm Bank, is venturing to address modern family build…

California, soaked from days of relentless rain and recovering from mudslides in mountain towns, was hit with another powerful storm Christmas Day that led to evacuation warnings and high surf advisories. The San Bernardino County Sheriff’s Department in Southern California issued an evacuation warning for Wrightwood, a mountain town about 80 miles (130 kilometers) northeast of Los Angeles, a day after rescuing people trapped in cars during a mud slide. The National Weather Service said waves near the San Francisco Bay Area could reach up to 25 feet (7.6 meters) Friday. Statewide, more than 70,000 people were without power Thursday afternoon, according to PowerOutage.u…

The biggest brands pour creativity into being instantly recognizable. A logo you can spot at 20 paces. A color palette that becomes cultural shorthand (think Oreo blue or Coca-Cola red). That visual obsession runs through every corner of marketing. TV, social, out-of-home, retail, and packaging. Millions go into crafting imagery, with every frame revised until it perfectly reinforces the brand. So, of course visuals matter—they always will matter. But the best performing brands aren’t blinded by them. They understand that a cohesive sonic identity that spans campaigns and touchpoints ensures your brand is remembered long after someone closes their phone or wal…

This article is republished with permission from Wonder Tools, a newsletter that helps you discover the most useful sites and apps. I like pushing AI to be less predictable. When AI assistants are less bland and more bold, they challenge my blind spots and nudge me to rethink. So I asked one of the boldest AI experimenters I know, Alexandra Samuel, to share unconventional tips and tactics when she visited New York recently from Vancouver. Alex, who writes about AI for The Wall Street Journal and Harvard Business Review, surprised me with the scale of her AI efforts. She described creating 200-plus automation scripts and building a personal idea database that h…

My working days often unfold in either Zoom minimalist workplaces or glass-walled conference rooms with sleek windows, filled with entrepreneurs pitching ideas. As a marketing executive and startup mentor, I lead strategies for companies of various sizes, guide founders at startup accelerators TechStars and Founder Institute, and serve as an awards jury member. My calendar overflows with executive consultations, brand campaign planning, and deadline sprints. But between Christmas and New Year’s, I trade those sterile spaces for museum halls alive with color and history. It wasn’t easy getting out the door the first time I did this in 2021. I was filled with fears.…

In 2025, AI became officially unavoidable: It had been lurking in the background before, as early adapters experimented with it. But this year, companies invested more than $202 billion in AI, a 75% increase from $114 billion invested in 2024. Major tech companies fought bitterly over AI talent, offering astronomical pay packages. There was a groundswell of demand for talent, and unsurprisingly this spread to the demand for AI, data science, and engineering jobs, which increased 28% compared to 2024, according to data provided to Fast Company by IT staffing company Mondo. The firm also provided data on the top five jobs that took off in 2025, which we’ve listed by vol…

The U.S. auto safety regulator said on Wednesday it has opened a defect investigation into Tesla Model 3 compact sedans over concerns that emergency door release controls may not be easily accessible or clearly identifiable in an emergency. The Office of Defects Investigation said the probe covers an estimated 179,071 model year 2022 vehicles. The investigation was opened on December 23 after the agency received a defect petition alleging that the vehicles’ mechanical door release is hidden, unlabeled, and not intuitive to locate during emergencies. Tesla did not immediately respond to a request for comment. The company’s vehicles rely primarily on electro…

It may be a very Merry Christmas for one lucky Powerball winner. The Christmas Eve Powerball jackpot is accumulating like a snowball tumbling down an epic sledding hill. The total is now so large, it’s a number rarely attainable even for high-stakes gamblers. The prize has continued to grow after five drawings worth at least $1 billion went unclaimed with no ticket matching all six numbers. According to the Powerball website, that makes the current prize of around $1.7 billion the fourth-largest in Powerball history. It’s also the longest the prize has ever gone without a winner. “Much like the holidays, Powerball is a game that brings people together to dream b…
