Microplastics From Washing Clothes Could Be Hurting Your Tomatoes
A new study from Cornell and University of Toronto researchers has found that polyester microfibers shed from synthetic clothing during laundry can interfere with cherry tomato plant development [non-paywalled source] when these particles accumulate in agricultural soil. Plants grown in contaminated soil were 11% less likely to emerge, grew smaller and took several days longer to flower and ripen.
Household laundry is a leading source of this contamination. Treated sewage sludge retains roughly 90% of microfibers from washers, and farmers in some countries apply this material to up to 75% of cropland as fertilizer. Some scientists have questioned the methodology.
Willie Peijnenburg, a professor of environmental toxicology at Leiden University, told WaPo the microfiber concentration used was much higher than field observations. His research suggests plants primarily absorb microplastics through airborne particles entering leaf stomata rather than through soil.

PhD Students' Taste For Risk Mirrors Their Supervisors'
A researchers' propensity for risky projects is passed down to their doctoral students -- and stays with trainees after they leave the laboratory, according to an analysis of thousands of current and former PhD students and their mentors. From a report: Science involves taking risks, and some of the most impactful discoveries require taking big bets. However, scientists and policymakers have raised concerns that the current academic system's emphasis on short-term outcomes encourages researchers to play it safe. Studies have shown, for example, that risky research is less likely to be funded. Anders Brostrom, an economist studying science policy at the University of Gothenburg in Sweden, and his colleagues decided to examine the role of doctoral education in shaping risk-related behaviour -- an area that Brostrom says has been largely overlooked.
"We often focus on thinking about how we can change the funding systems to make it more likely for people to take risks, but that's not the only lever we have," says Chiara Franzoni, an economist at the Polytechnic University of Milan in Italy. This study is "refreshing" because "we've discussed policy interventions a lot, but we haven't discussed training," she adds. [...] The team found that students' risk-taking dispositions matched those of their supervisors. This link was stronger when students and their supervisors communicated frequently, and weaker when students were also mentored by scientists outside their lab.

Partly AI-Generated Folk-Pop Hit Barred From Sweden's Official Charts
An anonymous reader shares a report: A hit song has been excluded from Sweden's official chart after it emerged the "artist" behind it was an AI creation. I Know, You're Not Mine -- or Jag Vet, Du Ar Inte Min in Swedish -- by a singer called Jacub has been a streaming success in Sweden, topping the Spotify rankings.
However, the Swedish music trade body has excluded the song from the official chart after learning it was AI-generated. "Jacub's track has been excluded from Sweden's official chart, Sverigetopplistan, which is compiled by IFPI Sweden. While the song appears on Spotify's own charts, it does not qualify for inclusion on the official chart under the current rules," said an IFPI Sweden spokesperson. Ludvig Werber, IFPI Sweden's chief executive, said: "Our rule is that if it is a song that is mainly AI-generated, it does not have the right to be on the top list."

Ads Are Coming To ChatGPT in the Coming Weeks
OpenAI said Friday that it will begin testing ads on ChatGPT in the coming weeks, as the $500 billion startup seeks new revenue streams to fund its continued expansion and compete against rivals Google and Anthropic. The company had previously resisted embedding ads into its chatbot, citing concerns that doing so could undermine the trustworthiness and objectivity of responses.
The ads will appear at the bottom of ChatGPT answers on the free tier and the $8-per-month ChatGPT Go subscription in the U.S., showing only when relevant to the user's query. Pro, Business, and Enterprise subscriptions will remain ad-free. OpenAI expects to generate "low billions" of dollars from advertising in 2026, FT reported, and more in subsequent years. The revenue is intended to help fund roughly $1.4 trillion in computing commitments over the next decade. The company said it will not show ads to users under 18 or near sensitive topics like health, mental health, or politics.

Seattle is Building Light Rail Like It's 1999
Seattle was late to the light rail party -- the city rejected transit ballot measures in 1968 and 1971, missing out on federal funding that built Atlanta's MARTA, and didn't approve a plan including rail until 1996 -- but the Pacific Northwest city is now in the middle of a multibillion-dollar building boom that has produced the highest post-pandemic ridership recovery of any US light rail system.
The Link system opened its first line in 2009, funded largely by voter-approved tax measures from 2008 and 2016. The north-south 1 Line now stretches 41 miles after a $3 billion extension to Lynnwood opened in June 2025 and a $2.5 billion leg to Federal Way debuted in December. Ridership is up 24% since 2019, and 3.4 million people rode Link trains in October 2025.
Test trains have been running since September across the I-90 floating bridge over Lake Washington -- what Sound Transit claims is the world's first light rail on a floating structure -- preparing for a May 31 opening. The Crosslake Connection is part of the 2 Line, a 14-mile, $3.7 billion extension voters approved in 2008 that was originally slated to open in 2020. The expansion hasn't come without problems. Sound Transit faces a roughly $30 billion budget shortfall, and a planned Ballard extension has ballooned to $22 billion, double original estimates.

AI Has Made Salesforce Engineers More Productive, So the Company Has Stopped Hiring Them, CEO Says
Salesforce CEO Marc Benioff said this week that his company's software engineering headcount has remained "mostly flat" over the past year as internal AI tools have delivered substantial productivity gains.
Speaking on TBPN, Benioff said he has about 15,000 engineers who are "more productive than ever." The company has redirected its hiring efforts toward sales and customer engagement roles, hiring 20% more account executives this year as it pushes its Agentforce agentic AI service.
Human salespeople remain essential for explaining the "intricacies and nuances" of agentic AI to skeptical enterprise customers, he argued. Other parts of the business have seen deeper cuts. In a separate appearance on The Logan Bartlett Show, Benioff said that Salesforce had reduced its customer support workforce by roughly 50%.

Ruby on Rails Creator Says AI Coding Tools Still Can't Match Most Junior Programmers
AI still can't produce code as well as most junior programmers he's worked with, David Heinemeier Hansson, the creator of Ruby on Rails and co-founder of 37 Signals, said on a recent podcast [video link], which is why he continues to write most of his code by hand. Hansson compared AI's current coding capabilities to "a flickering light bulb" -- total darkness punctuated by moments of clarity before going pitch black again.
At his company, humans wrote 95% of the code for Fizzy, 37 Signals' Kanban-inspired organization product, he said. The team experimented with AI-powered features, but those ended up on the cutting room floor. "I'm not feeling that we're falling behind at 37 Signals in terms of our ability to produce, in terms of our ability to launch things or improve the products," Hansson said.
Hansson said he remains skeptical of claims that businesses can fire half their programmers and still move faster. Despite his measured skepticism, Hansson said he marvels at the scale of bets the U.S. economy is placing on AI reaching AGI. "The entire American economy right now is one big bet that that's going to happen," he said.

China Clamps Down on High-Speed Traders, Removing Servers
An anonymous reader shares a report: China is pulling the plug on a key advantage held by high-frequency traders, removing servers dedicated to those firms out of local exchanges' data centers, according to people familiar with the matter.
Commodities futures exchanges in Shanghai and Guangzhou are among those that have ordered local brokers to shift servers for their clients out of data centers run by the bourses, according to the people, who said the move was led by regulators. The change doesn't only affect high-frequency firms but they are likely to feel the biggest impact. The Shanghai Futures Exchange has told brokers they need to get equipment for high-speed clients out by the end of next month, while other clients need to do so by April 30, the people said.
The clampdown will hit China's army of domestic high-frequency firms but will also impact a swathe of global firms that are active in the country. Citadel Securities, Jane Street Group and Jump Trading are among the foreign firms whose access to servers is being affected, the people said, asking not to be named as the matter is private.

Hard Drive Prices Have Surged By an Average of 46% Since September
Tom's Hardware: Extensive research into the pricing of some of the best hard drives on the market for large capacity, economical storage indicates that prices are beginning to increase sharply, with some of the most popular models on the market seeing increases upwards of 60%. According to research from ComputerBase, pricing analysis on 12 of the most popular mainstream drives on the market indicates an average price increase of 46% over the last 4 months.
While the research and price checks on these drives track movement based on European prices (ComputerBase is a German outlet), Tom's Hardware checks on similar or identical SKUs in the U.S. indicate that the trends are indeed replicated, or perhaps worse, on the other side of the pond. CB reports that various drives like Seagate's IronWolf NAS line, Toshiba's Cloud Scale Capacity Drives, Western Digital's WD Red, and Seagate's BarraCuda lines are all showing price increases of between 23% and 66%. As noted, the average price increases clock in at 46% since September 2025.
