Offices nationwide are ditching harsh fluorescent lighting in favor of advanced systems designed to improve cognitive function and entice remote workers back to physical workplaces. Companies are investing in circadian-tuned lighting that adjusts intensity and color temperature throughout the day to mimic natural light patterns, syncing with employees' biological rhythms, according to WSJ. The technology arsenal includes faux skylights displaying virtual suns and moons, AI-controlled self-tinting windows, and customizable lighting zones that can be adjusted via remote control. Research suggests these innovations may improve brain function during tasks requiring sustained attention. "We've known for a long time that natural light is better and makes people feel better," says Peter Cappelli, professor at Wharton School. The innovations stem from discoveries in the early 2000s of photosensitive retinal cells that affect biology independent of vision. Industry specialists report a "huge uptick in requests," though implementation adds 20-30% to project costs, potentially slowing mainstream adoption.

An anonymous reader shares a report: Canada has seen a boom in political books created with generative artificial intelligence, adding to concerns about how new technologies are affecting the information voters receive during the election campaign. Prime Minister Mark Carney was the subject of at least 16 books published in March and listed on Amazon.com, according to a review of the site on April 16. Five of those were published on a single day. In total, some 30 titles were published about Carney this year and made available on Amazon -- but most were taken down from the site after inquiries from Bloomberg News. One author, James A. Powell, put his name to at least three books about the former central banker, who's now leading the Liberal Party and is narrowly favored to win the election. Among the titles that Amazon removed: "Carney's Code: Climate Capitalism, Digital Currencies, and the Technocratic Takeover of the Global Economy -- Inside Mark Carney's Blueprint for the Post-Democratic World."

An anonymous reader shares a report: In a shocking development, Google won't roll out a new standalone prompt for third-party cookies in Chrome. It's a move that amounts to a U-turn on the Chrome team's earlier updated approach to deprecating third-party cookies, announced in July last year, with the latest development bound to cause ructions across the ad tech ecosystem. "We've made the decision to maintain our current approach to offering users third-party cookie choice in Chrome, and will not be rolling out a new standalone prompt for third-party cookies," wrote Anthony Chavez, vp Privacy Sandbox at Google, in a blog post published earlier today (April 22). "Users can continue to choose the best option for themselves in Chrome's Privacy and Security Settings." However, it's not the end of Privacy Sandbox, according to Google, as certain initiatives incubated within the project are set to continue, such as its IP Protection for Chrome Incognito users, which will be rolled out in Q3.

Abstract of a paper on National Bureau of Economic Research: We estimate the effect of social media deactivation on users' emotional state in two large randomized experiments before the 2020 U.S. election. People who deactivated Facebook for the six weeks before the election reported a 0.060 standard deviation improvement in an index of happiness, depression, and anxiety, relative to controls who deactivated for just the first of those six weeks. People who deactivated Instagram for those six weeks reported a 0.041 standard deviation improvement relative to controls. Exploratory analysis suggests the Facebook effect is driven by people over 35, while the Instagram effect is driven by women under 25.

An anonymous reader quotes a report from MIT Technology Review: Arete Glacier Initiative has raised $5 million to improve forecasts of sea-level rise and explore the possibility of refreezing glaciers in place. Off one atoll, just south of the Maldives' capital, Male, researchers are testing one way to capture sand in strategic locations -- to grow islands, rebuild beaches, and protect coastal communities from sea-level rise. Swim 10 minutes out into the En'boodhoofinolhu Lagoon and you'll find the Ramp Ring, an unusual structure made up of six tough-skinned geotextile bladders. These submerged bags, part of a recent effort called the Growing Islands project, form a pair of parentheses separated by 90meters (around 300 feet). The bags, each about two meters tall, were deployed in December 2024, and by February, underwater images showed that sand had climbed about a meter and a half up the surface of each one, demonstrating how passive structures can quickly replenish beaches and, in time, build a solid foundation for new land. "There's just a ton of sand in there. It's really looking good," says Skylar Tibbits, an architect and founder of the MIT Self-Assembly Lab, which is developing the project in partnership with the Male-based climate tech company Invena. The Self-Assembly Lab designs material technologies that can be programmed to transform or "self-assemble" in the air or underwater, exploiting natural forces like gravity, wind, waves, and sunlight. Its creations include sheets of wood fiber that form into three-dimensional structures when splashed with water, which the researchers hope could be used for tool-free flat-pack furniture.Growing Islands is their largest-scale undertaking yet. Since 2017, the project has deployed 10 experiments in the Maldives, testing different materials, locations, and strategies, including inflatable structures and mesh nets. The Ramp Ring is many times larger than previous deployments and aims to overcome their biggest limitation. In the Maldives, the direction of the currents changes with the seasons. Past experiments have been able to capture only one seasonal flow, meaning they lie dormant for months of the year. By contrast, the Ramp Ring is "omnidirectional," capturing sand year-round. "It's basically a big ring, a big loop, and no matter which monsoon season and which wave direction, it accumulates sand in the same area," Tibbits says. The approach points to a more sustainable way to protect the archipelago, whose growing population is supported by an economy that caters to 2 million annual tourists drawn by its white beaches and teeming coral reefs. Most of the country's 187 inhabited islands have already had some form of human intervention to reclaim land or defend against erosion, such as concrete blocks, jetties, and breakwaters.

Researchers have uncovered a new supply chain attack called Slopsquatting, where threat actors exploit hallucinated, non-existent package names generated by AI coding tools like GPT-4 and CodeLlama. These believable yet fake packages, representing almost 20% of the samples tested, can be registered by attackers to distribute malicious code. CSO Online reports: Slopsquatting, as researchers are calling it, is a term first coined by Seth Larson, a security developer-in-residence at Python Software Foundation (PSF), for its resemblance to the typosquatting technique. Instead of relying on a user's mistake, as in typosquats, threat actors rely on an AI model's mistake. A significant number of packages, amounting to 19.7% (205,000 packages), recommended in test samples were found to be fakes. Open-source models -- like DeepSeek and WizardCoder -- hallucinated more frequently, at 21.7% on average, compared to the commercial ones (5.2%) like GPT 4. Researchers found CodeLlama ( hallucinating over a third of the outputs) to be the worst offender, and GPT-4 Turbo ( just 3.59% hallucinations) to be the best performer. These package hallucinations are particularly dangerous as they were found to be persistent, repetitive, and believable. When researchers reran 500 prompts that had previously produced hallucinated packages, 43% of hallucinations reappeared every time in 10 successive re-runs, with 58% of them appearing in more than one run. The study concluded that this persistence indicates "that the majority of hallucinations are not just random noise, but repeatable artifacts of how the models respond to certain prompts." This increases their value to attackers, it added. Additionally, these hallucinated package names were observed to be "semantically convincing." Thirty-eight percent of them had moderate string similarity to real packages, suggesting a similar naming structure. "Only 13% of hallucinations were simple off-by-one typos," Socket added. The research can found be in a paper on arXiv.org (PDF).

Airbnb is rolling out a global update that displays the total cost of a stay upfront in search results. The only fee that won't be included are taxes. The Verge reports: The company first started showing the full price of its listings in some locations in 2019 after facing scrutiny from the European Union over how it displays its fees. It later launched a toggle in the US and hundreds of other countries that shows the total cost of a stay across Airbnb's search results, individual listings pages, and other areas of the platform. Airbnb says nearly 17 million people have used the toggle since its launch in 2022, and now, you won't have to worry about turning the option on when making a search. Instead, you'll now see a banner at the very top of your search results that says, "Prices include all fees."

Microsoft is intensifying performance scrutiny through new policies that target underperforming employees, according to an internal email from Chief People Officer Amy Coleman. The company has introduced a formalized Performance Improvement Plan (PIP) system that gives struggling employees two options: accept improvement targets or exit the company with a Global Voluntary Separation Agreement. The policy establishes a two-year rehire blackout period for employees who leave with low performance ratings (zero to 60% in Microsoft's 0-200 scale) or during a PIP process. These employees are also barred from internal transfers while still at the company. Coming months after Microsoft terminated 2,000 underperformers without severance, the company is also developing AI-supported tools to help managers "prepare for constructive or challenging conversations" through interactive practice environments. "Our focus remains on enabling high performance to achieve our priorities spanning security, quality, and leading AI," Coleman wrote, emphasizing that these changes aim to create "a globally consistent and transparent experience" while fostering "accountability and growth."

CATL has unveiled a second-generation Shenxing battery capable of delivering a 520km range in just five minutes of charging, surpassing BYD's recent breakthrough and positioning both Chinese firms ahead of Western rivals in EV battery tech. The battery manufacturer also introduced a sodium-ion battery called Naxtra, offering up to 500km range for EVs and potential to diversify global energy resources. The Financial Times reports: The claims by the Chinese battery groups would put them ahead of major western rivals. At present, Tesla vehicles can be charged up to 200 miles (321km) in added range in 15 minutes, while Germany's Mercedes-Benz recently launched its all-electric CLA compact sedan, which can be charged for up to 325km within 10 minutes using a fast-charging station. [...] The second generation of the Shenxing battery, which boasts a range of 800km on one charge, can achieve a peak charging speed of 2.5km per second, the company said at a media event ahead of this week's Shanghai auto show. "We look forward to collaborating with more industry leaders to push the limits of supercharging through true innovation," said CATL's chief technology officer Gao Huan, adding that he wanted the new batteries to become "the standard for electric vehicles." Analysts at Bernstein said the latest progress meant that charging speeds had more than doubled in the past year and "increased tenfold over the past 3-4 years." Huan said the new Shenxing battery would be installed in more than 67 EV models this year. He later told reporters that energy density would not be sacrificed as a trade-off for fast charging. During its tech day, CATL also unveiled its new sodium-ion battery, which it said would go into mass production in December. The battery brand called Naxtra is able to give a range of about 200km for a hybrid vehicle and 500km for an electric vehicle, according to Huan. [...] At the event, Huan claimed the new sodium-ion battery would enable the industry's shift from "single resource dependence" to "energy freedom" and reshape the global energy landscape. He added that he was in discussions with several companies about using sodium-ion batteries in their vehicles.
