If you think your daily doses of espresso or Earl Grey sharpen your mind, you just might be right, new science suggests. The New York Times: A large new study provides evidence of cognitive benefits from coffee and tea — if it’s caffeinated and consumed in moderation: two to three cups of coffee or one to two cups of tea daily.

People who drank that amount for decades had lower chances of developing dementia than people who drank little or no caffeine, the researchers reported. They followed 131,821 participants for up to 43 years. “This is a very large, rigorous study conducted long term among men and women that shows that drinking two or three cups of coffee per day is associated with reduced risk of dementia,” said Aladdin Shadyab, an associate professor of public health and medicine at the University of California, San Diego, who wasn’t involved in the study.

The findings, published Monday in JAMA, don’t prove caffeine causes these beneficial effects, and it’s possible other attributes protected caffeine drinkers’ brain health. But independent experts said the study adjusted for many other factors, including health conditions, medication, diet, education, socioeconomic status, family history of dementia, body mass index, smoking and mental illness.

Deepfake fraud has gone “industrial,” an analysis published by AI experts has said. From a report: Tools to create tailored, even personalised, scams — leveraging, for example, deepfake videos of Swedish journalists or the president of Cyprus — are no longer niche, but inexpensive and easy to deploy at scale, said the analysis from the AI Incident Database.

It catalogued more than a dozen recent examples of “impersonation for profit,” including a deepfake video of Western Australia’s premier, Robert Cook, hawking an investment scheme, and deepfake doctors promoting skin creams. These examples are part of a trend in which scammers are using widely available AI tools to perpetuate increasingly targeted heists. Last year, a finance officer at a Singaporean multinational paid out nearly $500,000 to scammers during what he believed was a video call with company leadership. UK consumers are estimated to have lost $12.86bn to fraud in the nine months to November 2025.

“Capabilities have suddenly reached that level where fake content can be produced by pretty much anybody,” said Simon Mylius, an MIT researcher who works on a project linked to the AI Incident Database. He calculates that “frauds, scams and targeted manipulation” have made up the largest proportion of incidents reported to the database in 11 of the past 12 months. He said: “It’s become very accessible to a point where there is really effectively no barrier to entry.”

An anonymous reader shares a report: It turns out that when fewer cars spew exhaust as they drive along, air quality improves. That’s the conclusion of a new study published in The Lancet Planetary Health that looked at the effect of increased numbers of both EVs and plug-in hybrids on air pollution in California. The Golden State has by far the largest number of plug-in vehicles in the United States, and they’ve now reached significant numbers to have a positive impact on air quality.

Between 2019 and 2023, for every 200 EVs or plug-in hybrids added, nitrogen dioxide (NO2) levels dropped 1.1%, according to the study, which used satellite data to track those levels through the unique way NO2 absorbs and reflects sunlight. NO2 can trigger asthma attacks, cause bronchitis, and increase the risk of heart disease and stroke.

A new NBER working paper from researchers at the Federal Reserve, Northwestern’s Kellogg School and Johns Hopkins finds that Kalshi — the largest federally regulated prediction market in the U.S., overseen by the CFTC — produces macroeconomic forecasts that match or beat those of professional forecasters and traditional financial instruments like fed funds futures.

The study compared Kalshi-implied forecasts for the federal funds rate, CPI inflation and unemployment against the New York Fed’s Survey of Market Expectations and Bloomberg consensus. Kalshi’s modal forecast correctly predicted the federal funds rate on the day before every FOMC meeting since 2022, something neither the survey nor fed funds futures achieved. For headline CPI, Kalshi’s median and mode produced a statistically significant improvement over Bloomberg consensus.

Kalshi also fills a gap no other financial market covers: real-time probability distributions for GDP growth, core CPI, unemployment, and payrolls. The paper documented how these distributions shift in response to macro news — positive CPI surprises moved the mean of the fed funds rate distribution four times more than negative ones. Trading volumes on the platform have grown to nearly 100 million contracts for a single FOMC meeting, supported by liquidity from Susquehanna, Citadel, and Two Sigma.

This is a video from the fun/danger-loving crew DD Squad (I’m part of a small B Squad myself) using a custom built rig to launch a human at 50MPH from the rear of a truck traveling at 50MPH so that he can just stand the landing, since 50MPH – 50MPH = 0MPH. It works surprisingly well, and, unlike if I’d been involved, nobody was accidentally launched into the side of a cliff at 200MPH then crushed by an anvil Wile E. Coyote style.

In 2023, we marveled at the sheer mass of Lenovo’s Legion Go, a 1.88-pound, 11.8-inch-wide monstrosity of a Windows gaming handheld. In 2026, though, Ayaneo unveiled details of its Next II handheld, which puts Lenovo’s big boy to shame while also offering heftier specs and a higher price than most other Windows gaming handhelds.

Let’s focus on the bulk first. The Ayaneo Next II weighs in at a truly wrist-straining 3.14 pounds, making it more than twice as heavy in the hands as the Steam Deck OLED (not to mention 2022’s original Ayaneo Next, which weighed a much more reasonable 1.58 pounds). The absolute unit also measures 13.45 inches wide and 10.3 inches tall, according to Ayaneo’s spec sheet, giving it a footprint approximately 60 percent larger than the Switch 2 (with Joy-Cons attached).

Ayaneo packs some seriously powerful portable PC performance into all that bulk, though. The high-end version of the system sports a Ryzen AI Max+ 395 chipset with 16 Zen5 cores alongside a Radeon 8060S with 40 RDNA3.5 compute units. That should give this massive portable performance comparable to a desktop with an RTX 4060 or a gaming laptop like last year’s high-end ROG Flow Z13.

It finally happened. After months of speculation, ChatGPT officially has ads. OpenAI revealed the news on Monday, announcing that ads would roll out in testing for logged-in adult users on Free and Go subscriptions. If you or your organization pays for ChatGPT, such as with a Plus, Pro, Business, Enterprise, or Education account, you won’t see ads with the bot.

OpenAI says that ads do not have an impact on the answers ChatGPT generates, and that these posts are always clearly separated from ChatGPT’s actual responses. In addition, ads are labeled as “Sponsored.” That being said, it’s not exactly a church-and-state situation here. OpenAI says that it decides which ads to show you based on your current and past chats, as well as your past interactions with ChatGPT ads. If you’re asking for help with a dinner recipe, you might get an ad for a meal kit or grocery service.

The company claims it keeps your chats away from advertisers. The idea, according to the company, is strictly funding-based so that OpenAI can expand ChatGPT access to more users. That’s reportedly why ads are starting as a test, not a hardcoded feature: OpenAI says it wants to “learn, listen, and make sure [it gets] the experience right.” As such, advertisers don’t have access to chats, chat histories, memories, or your personal details. They do have access to aggregate information about ad performance, including views and click metrics.

OpenAI will only show ads to adults. If the service detects that you are under 18, it will block ads from populating in your chats. Ads also will not appear if you’re talking to ChatGPT about something related to health, medicine, or politics. You can offer OpenAI feedback on the ads you do see, which should inform the ads you receive in the future. You can also delete your ad data and manage ad personalization, if you want to reset the information OpenAI is using to send you ads.

How to opt out of ChatGPT ads

The thing is, you don’t actually have to deal with ads, even if you use ChatGPT for free. That’s not just by upgrading to a paid ChatGPT plan, though OpenAI does suggest that option in its announcement. In addition, OpenAI is offering Free and Go users a dedicated choice to opt out of ads here. There is, of course, a pretty sizable catch: You have to agree to fewer daily free messages with ChatGPT. OpenAI doesn’t offer specifics here, so it’s not clear how limited the ad-free experience will be. But if you hate ads, or if you simply don’t want to see an ad for something irrelevant to your ChatGPT conversation, it’s an option.

If you like that trade-off, here’s how to opt out of ads. Open ChatGPT, then head to your profile, which opens your profile’s Settings page. Here, scroll down to “Ads controls,” then choose “Change plan to go ad-free.” Select “Reduce message limits,” and ChatGPT will confirm ads are off for your account. You can return to this page at any time to turn ads back on and restore your message limits.
