Never learned to play chess and don’t know where to start? Duolingo, the gamified education app most famous for its language learning lessons, is adding chess lessons to the iPhone application later this month. You can learn how each piece moves before eventually moving on to tactics, all in the familiar Duolingo user interface.

A “limited number of learners” on iOS will get the chess feature on Tuesday, April 22; it will roll out to other English-speaking iPhone users “in weeks following.” Other operating systems, along with versions for non-English speakers, are “planned in the months ahead,” according to Duolingo.

This isn’t the first offering outside of language learning offered by the application—the application currently has offered math and music lessons since 2023. The math lessons, which I’ve tried, are a great way to refresh your multiplication tables, while the music lessons go over the basics of music theory while also featuring rhythm-game-link sequences built around actual pop songs.

The chess lessons are a departure, though, by teaching you to play a game instead of a language or academic subject. “Chess is an ideal fit for Duolingo,” Luis von Ahn, co-founder and CEO of Duolingo, said in a press release. “It sharpens your brain, it’s packed with strategy, and like language learning, it’s a skill that gets better with practice.”

The app is intended to make chess more accessible, so it should be no surprise that the lessons themselves are intended for beginners, starting from the mechanics about how each piece moves before moving on to tactics and strategy. The average lesson is built around short puzzles—you may, for example, be asked to checkmate the opposition in a single move. There are also mini-matches, and even full chess games, all played against Oscar (the cartoon mustachioed man with a memorable deep voice, long featured in Duolingo’s language learning courses).

A new study projects that CT scans conducted in 2023 may result in around 103,000 future cancer cases in the U.S. due to low-dose ionizing radiation. “[I]t would put CT scans on par with other significant risk factors for cancer, like alcohol consumption, at least at a population level,” reports ScienceAlert. From the report: At an individual level, the theoretical chance of developing cancer from a CT scan is thought to be very minimal, if it exists at all, and patients should not be scared of undergoing these tests if they are deemed medically necessary. However, the number of CT examinations performed each year in the US has increased by more than 30 percent since 2007, and researchers suggest that unwarranted tests are exposing the population to unnecessary radiation. […]

The anonymous data comes from 143 hospitals and outpatient facilities across the US, catalogued in the UCSF International CT Dose Registry. Using statistics from 2016 to 2022, researchers predicted 93 million CT examinations were carried out in 2023, on roughly 62 million patients. Based on the associated radiation risks, the team estimates that CT scans in 2023 may be tied to 103,000 future cancers. The findings have been published in JAMA Internal Medicine.

An anonymous reader shares a report: Generative AI offers remarkable efficiency gains while presenting a profound challenge for the global IT services industry — a sector concentrated in India and central to its export economy.

For decades, Indian technology firms thrived by deploying their engineering talent to serve primarily Western clients. Now they face a critical question. Will AI’s productivity dividend translate into revenue growth? Or will fierce competition see these gains competed away through price reductions?

Industry soundings suggest the deflationary dynamic may already be taking hold. JPMorgan’s conversations with executives, deal advisors and consultants across India’s technology hubs reveal growing concern — AI-driven efficiencies are fuelling pricing pressures. This threatens to constrain medium-term industry growth to a modest 4-5%, with little prospect of acceleration into fiscal year 2026. This emerging reality challenges the earlier narrative that AI would primarily unlock new revenue streams.

An anonymous reader quotes a report from Forbes: Robotaxi development is speeding at a fast pace in China, but we don’t hear much about it in the USA, where the news focuses mostly on Waymo, with a bit about Zoox, Motional, May, trucking projects and other domestic players. China has 4 main players with robotaxi service, dominated by Baidu (the Chinese Google.) A recent session at last week’s Ride AI conference in Los Angeles revealed some details about the different regulatory regime in China, and featured a report from a Chinese-American YouTuber who has taken on a mission to ride in the different vehicles.

Zion Maffeo, deputy general counsel for Pony.AI, provided some details on regulations in China. While Pony began with U.S. operations, its public operations are entirely in China, and it does only testing in the USA. Famously it was one of the few companies to get a California “no safety driver” test permit, but then lost it after a crash, and later regained it. Chinese authorities at many levels keep a close watch over Chinese robotaxi companies. They must get approval for all levels of operation which control where they can test and operate, and how much supervision is needed. Operation begins with testing with a safety driver behind the wheel (as almost everywhere in the world,) with eventual graduation to having the safety driver in the passenger seat but with an emergency stop. Then they move to having a supervisor in the back seat before they can test with nobody in the vehicle, usually limited to an area with simpler streets.

The big jump can then come to allow testing with nobody in the vehicle, but with full time monitoring by a remote employee who can stop the vehicle. From there they can graduate to taking passengers, and then expanding the service to more complex areas. Later they can go further, and not have full time remote monitoring, though there do need to be remote employees able to monitor and assist part time. Pony has a permit allowing it to have 3 vehicles per remote operator, and has one for 15 vehicles in process, but they declined comment on just how many vehicles they actually have per operator. Baidu also did not respond to queries on this. […] In addition, Chinese jurisdictions require that the system in a car independently log any “interventions” by safety drivers in a sort of “black box” system. These reports are regularly given to regulators, though they are not made public. In California, companies must file an annual disengagement report, but they have considerable leeway on what they consider a disengagement so the numbers can’t be readily compared. Chinese companies have no discretion on what is reported, and they may notify authorities of a specific objection if they wish to declare that an intervention logged in their black box should not be counted. On her first trip, YouTuber Sophia Tung found Baidu’s 5th generation robotaxi to offer a poor experience in ride quality, wait time, and overall service. However, during a return trip she tried Baidu’s 6th generation vehicle in Wuhan and rated it as the best among Chinese robotaxis, approaching the quality of Waymo.

The climate crisis has tripled the length of ocean heatwaves, a study has found, supercharging deadly storms and destroying critical ecosystems such as kelp forests and coral reefs. From a report: Half of the marine heatwaves since 2000 would not have happened without global heating, which is caused by burning fossil fuels. The heatwaves have not only become more frequent but also more intense: 1C warmer on average, but much hotter in some places, the scientists said.

The research is the first comprehensive assessment of the impact of the climate crisis on heatwaves in the world’s oceans, and it reveals profound changes. Hotter oceans also soak up fewer of the carbon dioxide emissions that are driving temperatures up. “Here in the Mediterranean, we have some marine heatwaves that are 5C hotter,” said Dr Marta Marcos at the Mediterranean Institute for Advanced Studies in Mallorca, Spain, who led the study. “It’s horrible when you go swimming. It looks like soup.”

As well as devastating underwater ecosystems such as sea grass meadows, Marcos said: “Warmer oceans provide more energy to the strong storms that affect people at the coast and inland.”

Apple will begin analyzing data on customers’ devices in a bid to improve its AI platform, a move designed to safeguard user information while still helping it catch up with AI rivals. From a report: Today, Apple typically trains AI models using synthetic data — information that’s meant to mimic real-world inputs without any personal details. But that synthetic information isn’t always representative of actual customer data, making it harder for its AI systems to work properly.

The new approach will address that problem while ensuring that user data remains on customers’ devices and isn’t directly used to train AI models. The idea is to help Apple catch up with competitors such as OpenAI and Alphabet, which have fewer privacy restrictions. The technology works like this: It takes the synthetic data that Apple has created and compares it to a recent sample of user emails within the iPhone, iPad and Mac email app. By using actual emails to check the fake inputs, Apple can then determine which items within its synthetic dataset are most in line with real-world messages.

Samsung has paused the global rollout of its One UI 7 update after a serious bug was reported that prevented some Galaxy S24 owners from unlocking their phones. The Verge reports: While the complaints seem to have specifically come from South Korean owners of Galaxy S24 series handsets, Samsung has played it safe and paused the rollout across all models worldwide. While some users will have already downloaded the update to One UI 7, using the app CheckFirm we’ve confirmed that the update is no longer listed on Samsung’s servers as the latest firmware version across several Galaxy devices, with older patches appearing instead. Samsung hasn’t confirmed the pause in the rollout, nor plans to issue a fix for users who have already downloaded the One UI 7 update. We’ve reached out to the company for comment.

Computed tomography scans have become vital, even lifesaving, medical imaging for diagnosing and monitoring health conditions. But they do expose patients to ionizing radiation at levels linked to higher risks of cancer. In a new study in JAMA Internal Medicine, researchers tried to estimate what those higher risks are exactly—and although the estimates come with uncertainty, they may seem startling.

Based on data from 93 million CT scans performed on 62 million people in 2023, the researchers estimated that the CT scans would lead to 103,000 future cancers. To put that in context, those 103,000 cancers would account for about 5 percent of cancers diagnosed each year, based on the current cancer rates and the current usage of CT scans. And the estimate puts CT scans on par with alcohol consumption and obesity in terms of risk factors for developing cancer.

The most common types of cancers estimated to be a result of CT scans were lung cancer and colon cancer—two cancers that are becoming more common in younger people for reasons experts do not fully understand. The types of CT scans linked to the greatest number of cancers were abdomen and pelvis CT scans.

Espresso Displays makes some of our favorite portable monitors, but up until now, it felt like there was a hole in its portfolio. That’s because aside from its flagship model — the $800 Espresso 17 Pro — the other members of the family are slightly more affordable fare like the $469 Espresso Touch 13 and $499 Touch 15. Today, the company is plugging that gap with the Espresso 15 Pro, which packs everything I like about its bigger sibling in a more portable package for $699 (with a stand included).

Design and display

One of the things I appreciate about Espresso is that it doesn’t try to do too much. The 15 Pro features an ultra minimalist design made from simple sheets of matte black aluminum along with glossy glass in front (if you prefer matte displays, you can always add one of the company’s textured screen protectors). Granted, the monitor does have a bit of a chin, but aside from two USB-C ports stashed in the corner, that’s really the 15 Pro’s only defining exterior feature, so I’m not that bothered. All told, the display weighs 1 pound and 11 ounces, which sounds a lot heavier than it feels.

As for its specs, the Espresso 15 Pro’s 4K LCD panel delivers nearly everything you want and then some. Brightness tops out at 550 nits (it was actually 556 nits according to my light meter), which is higher than the 450 nits on the 17-inch model. It also covers 100 percent of the Adobe RGB spectrum with 10-bit color (8-bit + 2-bit frame rate control). The one thing I wish Espresso included was a 120Hz refresh rate instead of being capped at 60Hz. That said, unless you’re gaming or editing videos, that limitation may not be a huge factor.

Setup and special features

Sam Rutherford for Engadget

Getting the 15 Pro up and running couldn’t be easier. Each USB-C port has enough bandwidth to carry power and data over a single cable, so you just need to plug in the included cord, and off you go. The one exception is for laptops that can’t send out much power via USB-C, but I tested the monitor with 4 different laptops (both Mac and PC) and none of them had issues. The display even automatically downloaded the EspressoFlow software, which adds touch support to your Apple notebooks. You also get the new Glide feature that automatically positions the monitor in the right place depending on how you have it arranged next to your laptop. And by some black magic, the 15 Pro nailed it when it correctly laid out the monitor to the left of my notebook’s built-in screen.

As someone who has recently been forced to use a Mac for work, the ability to quickly and easily add touch support to Apple’s laptop is super nice. And while I’m far from a digital Degas, you can even use the display for drawing and sketching as the monitor also works with the company’s optional stylus. This makes the 15 Pro an ideal travel companion for both people who want more screen real estate or a portable way of creating art on the go.

Accessories

In addition to screen protectors and pens, there are also a couple of important stand accessories for the 15 Pro. The first is the $49 Espresso Case, which is more of a magnetic folding cover that protects the screen while in transit that can also flip around back to become a kickstand when you’re working. Like the display itself, it’s a fairly simple affair that does exactly what you expect it to.

However, for those who want something more substantial, the 15 Pro also works with Espresso’s $69 Stand+. It’s more like what you’d see on a traditional desktop monitor, except that it can fold up for improved portability while also packing a really strong magnet that allows you to mount the monitor in a variety of positions. This thing might be too pricey for some, but I’ve quickly grown to appreciate how easy it makes putting the 15 Pro in the perfect position. It’s more well-built than a lot of the desktop monitor stands I have. The obvious drawback is that at 1 pound and 4 ounces, the Stand+ weighs almost as much as the display itself, which is rather hefty.

Wrap-up

Sam Rutherford for Engadget

The Espresso 15 Pro has nearly everything I look for in a premium portable monitor. It features well above average brightness, a sleek but sturdy design and super simple setup. It also comes with a few special features like Glide and added touch support for Macs that help you get more out of the devices you already own. And thanks to a wealth of accessories, it can adapt to almost any use case.

While I’d like a higher refresh rate, not having it is far from a deal-breaker. That would almost certainly increase its price, and considering that the 15 Pro is already somewhat costly, starting at $699 for the monitor and the Stand+, I’m not sure the added expense would be worth it. Regardless, if you want a really portable monitor that’s also more than good enough to use at home, there aren’t many other displays that can match the Espresso 15 Pro.

A new investigation reveals that children as young as five can easily access inappropriate content and interact unsupervised with adults on Roblox, despite the platform’s child-friendly image and recent safety updates. The Guardian reports: Describing itself as “the ultimate virtual universe,” Roblox features millions of games and interactive environments, known collectively as “experiences.” Some of the content is developed by Roblox, but much of it is user-generated. In 2024, the platform had more than 85 million daily active users, an estimated 40% of whom are under 13. While the company said it “deeply sympathized” with parents whose children came to harm on the platform, it said “tens of millions of people have a positive, enriching and safe experience on Roblox every day.”

However, in an investigation shared with the Guardian, the digital-behavior experts Revealing Reality discovered “something deeply disturbing … a troubling disconnect between Roblox’s child-friendly appearance and the reality of what children experience on the platform.” […] Despite new tools launched last week aimed at giving parents more control over their children’s accounts, the researchers concluded: “Safety controls that exist are limited in their effectiveness and there are still significant risks for children on the platform.”

The Trump administration has been using federal research funding as a cudgel. The government has blocked billions of dollars in research funds and threatened to put a hold on even more in order to compel universities to adopt what it presents as essential reforms. In the case of Columbia University, that includes changes in the leadership of individual academic departments.

On Friday, the government sent a list of demands that it presented as necessary to “maintain Harvard’s financial relationship with the federal government.” On Monday, Harvard responded that accepting these demands would “allow itself to be taken over by the federal government.” The university also changed its home page into an extensive tribute to the research that would be eliminated if the funds were withheld.

Diversity, but only the right kind

Harvard posted the letter it received from federal officials, listing their demands. Some of it is what you expect, given the Trump administration’s interests. The admissions and hiring departments would be required to drop all diversity efforts, with data on faculty and students to be handed over to the federal government for auditing. As at other institutions, there are also some demands presented as efforts against antisemitism, such as the defunding of pro-Palestinian groups. More generally, it demands that university officials “prevent admitting students hostile to the American values and institutions.”

Intel will sell a 51% stake in its Altera programmable chip unit to private equity firm Silver Lake for $4.46 billion, aiming to cut costs, raise cash, and streamline the company’s focus as it shifts toward becoming a contract chip manufacturer. CNBC reports: The deal, announced on Monday, values Altera at $8.75 billion, a sharp decline from the $17 billion Intel paid in 2015. […] Since last year, Intel has taken steps to spin Altera out as a separate unit and said it planned to sell a portion of its stake. “Today’s announcement reflects our commitment to sharpening our focus, lowering our expense structure and strengthening our balance sheet,” [CEO Lip-Bu Tan], who took the helm after former top boss Pat Gelsinger’s ouster, said.

Altera makes programmable chips that can be used for various purposes from telecom equipment to military. Reuters had first reported in November that Silver Lake was among potential suitors competing for a minority stake in Altera. The deal is expected to close in the second half of 2025, after which Intel expects to deconsolidate Altera’s financial results from Intel’s financial statements, the company said.
