  • EPA Flags Microplastics, Pharmaceuticals As Contaminants In Drinking Water
    by BeauHD on 03/04/2026 at 3:30 am

    An anonymous reader quotes a report from NPR: Responding to public health concerns about microplastics and pharmaceuticals in the nation's drinking water, the Trump administration for the first time has placed them on a draft list of contaminants maintained by the Environmental Protection Agency. The EPA announced the move Thursday, touting it as a "historic step" for the Make America Healthy Again, or MAHA, movement, which often raises concerns about toxic chemicals and plastic pollution in our food and environment. Also Thursday, the Department of Health and Human Services announced a $144 million initiative, called STOMP, to develop tools to measure and monitor microplastics in drinking water and in a later stage, to remove them. The Safe Drinking Water Act requires the EPA to publish an updated version of its Contaminant Candidate List every five years. This is the sixth iteration of the list. Microplastics and pharmaceuticals appear in the draft of the upcoming list, alongside per- and polyfluoroalkyl substances, or PFAS, and dozens of other chemicals and microbes. Their inclusion on the list gives local regulators a tool to evaluate risks in their water supply, the EPA says, and it can set the stage for more research and regulatory action -- but doesn't actually guarantee that will happen.

  • Mount Everest Climbers 'Poisoned' By Guides In Insurance Fraud Scheme
    by BeauHD on 02/04/2026 at 11:00 pm

    schwit1 shares a report from the Kathmandu Post: In Nepal, helicopter rescue on high altitude is, by any measure, a genuine lifesaving operation. At high altitude, where oxygen thins and weather changes without warning, the ability to airlift a stricken trekker to Kathmandu within hours has saved countless lives. But threaded through that legitimate system, exploiting its urgency, its opacity, and its distance from oversight, is one of the most sophisticated insurance fraud networks in the world. Nepal's fake rescue scam is not new. The Kathmandu Post first exposed it in 2018. Months later, the government convened a fact-finding committee, produced a 700-page report, and announced reforms. In February 2019, The Kathmandu Post published a long investigative report. Last year, Nepal Police's Central Investigation Bureau reopened the file, and what they found is that the fraud did not stop -- instead it was growing. The mechanics of the fake rescue racket are straightforward: stage a medical emergency, call in a helicopter, check a tourist into a hospital, and file an insurance claim that bears little resemblance to what actually happened. But the sophistication lies in how each link in the chain is compensated, and how difficult it is for a foreign insurer -- operating from Australia and the United Kingdom -- to verify events that occurred at 3,000 metres in a remote Himalayan valley. The CIB investigation identifies two primary methods for manufacturing an "emergency." The first involves tourists who simply don't want to walk back. After completing a demanding trek -- an Everest Base Camp trek, for instance, can take up to two weeks on foot -- guides offer an alternative: pretend to be sick, and a helicopter will come. The guide handles the rest. The second method is more troubling. At altitudes above 3,000 meters, mild symptoms of altitude sickness are common. Blood oxygen saturation can drop, hands and feet tingle, headaches develop. In most cases, rest, hydration or a gradual descent is all that is needed. But guides and hotel staff, according to the CIB investigation, have been trained to terrify trekkers at precisely this moment. They tell them they are at risk of dying, that only immediate evacuation will save them. In some cases, investigators found that Diamox (Acetazolamide) tablets, used to prevent altitude sickness, were administered alongside excessive water intake to induce the very symptoms that would justify a rescue call. In at least one case cited in the investigation, baking powder was mixed into food to make tourists physically unwell. Once a "rescue" is called, the financial choreography begins. A single helicopter carries multiple passengers. But separate, full-price invoices are submitted to each passenger's insurance company, as if each had their own dedicated flight. A $4,000 charter becomes a $12,000 claim. Fake flight manifests and load sheets are fabricated. At the hospital, medical officers prepare discharge summaries using the digital signatures of senior doctors who were never involved in the case. In some cases, these are done without those doctors' knowledge. Fake admission records are created for tourists who were, in some documented instances, drinking beer in the hospital cafeteria at the time they were supposedly receiving treatment. In one case, an office assistant at Shreedhi Hospital admitted that he had provided his own X-ray report taken about a year ago at a different hospital, to be used as a case for treatment of foreign trekkers to claim insurance. The commission structure that holds the network together was described in detail during police interrogations. Hospitals pay 20 to 25 percent of the insurance payment to trekking companies and a further 20 to 25 percent to helicopter rescue operators in exchange for patient referrals. Trekking guides and their companies benefit from inflated invoices. In some cases, tourists themselves are offered cash incentives to participate. Read more of this story at Slashdot.

  • OpenAI Acquires Popular Tech-Industry Talk Show TBPN
    by BeauHD on 02/04/2026 at 10:00 pm

    OpenAI is acquiring tech news podcast TBPN, a fast-growing daily show hosted by John Coogan and Jordi Hays. OpenAI says TBPN will keep its editorial independence, even though the acquisition is widely viewed as part of a broader effort to influence public discourse around AI. CNBC reports: In the announcement, OpenAI CEO of AGI Deployment Fidji Simo wrote that their mission of bringing artificial general intelligence comes with a responsibility to have a space for "constructive conversation about the changes AI creates." Altman has appeared on TBPN multiple times and is a frequent presence across media and podcasts, even hitting NBC's "Tonight Show Starring Jimmy Fallon" in December. The announcement says TBPN will maintain editorial independence and continue to choose its own guests. "TBPN is my favorite tech show. We want them to keep that going and for them to do what they do so well," Altman wrote in a post on X. "I don't expect them to go any easier on us, am sure I'll do my part to help enable that with occasional stupid decisions." OpenAI did not disclose the terms of the deal but said TBPN will be housed within its strategy organization. "While we've been critical of the industry at times, after getting to know Sam and the OpenAI team, what stood out most was their openness to feedback and commitment to getting this right," wrote Hays in a statement. "Moving from commentary to real impact in how this technology is distributed and understood globally is incredibly important to us." Read more of this story at Slashdot.

  • Amazon Imposes 3.5% Fuel Surcharge For Many Online Merchants
    by BeauHD on 02/04/2026 at 9:00 pm

    An anonymous reader quotes a report from Bloomberg: Amazon will start charging sellers who use its shipping services a 3.5% "fuel and logistics" surcharge later this month, joining the ranks of shipping companies raising prices as the war in Iran pushes oil prices higher. The fees take effect on April 17 for customers of the company's Fulfillment by Amazon service -- which is used by many of the independent sellers who list their products on Amazon's retail sites -- in the US and Canada. Items shipped by Amazon on behalf of merchants who sell on their own sites or at other retailers will carry the surcharge beginning May 2. "Elevated costs in fuel and logistics have increased the cost of operating across the industry," Ashley Vanicek, an Amazon spokesperson, said on Thursday. "We have absorbed these increases so far, but similar to other major carriers, when costs remain elevated we implement temporary surcharges to partially recover these costs." Vanicek notes that the fee will apply to the sum Amazon charges to ship an item, not the product's sale price. Last month, USPS announced that it would impose its first-ever fuel surcharge on packages. Read more of this story at Slashdot.

  • IBM Teams Up With Arm To Run Arm Workloads On IBM Z Mainframes
    by BeauHD on 02/04/2026 at 8:00 pm

    IBM and Arm are teaming up to let Arm-based software run on IBM Z mainframes. Network World reports: The two companies plan to work on three things: building virtualization tools so Arm software can run on IBM platforms; making sure Arm applications meet the security and data residency rules that regulated industries must follow; and creating common technology layers so enterprises have more software options across both platforms, IBM said in a statement. IBM has not said whether the virtualization work will happen at the hypervisor level, through its existing PR/SM partitioning technology, or via containers -- a question enterprise architects will need answered before they can assess the collaboration's practical value. IBM described the effort as serving enterprises that run regulated workloads and cannot simply move them to the cloud, the statement said. IBM mainframe customers have largely missed out on the efficiency and price-performance gains Arm has already delivered in the cloud. "Arm says close to half of all compute shipped to top hyperscalers in 2025 runs on Arm chips, with AWS, Google, and Microsoft deploying their own Arm silicon through Graviton, Axion, and Cobalt, respectively," reports Network World. That gap is precisely what IBM and Arm's collaboration intends to address. "This is a mainframe adjacency play," says Rachita Rao, senior analyst at Everest Group. "The intent is to extend IBM Z and LinuxONE environments by enabling Arm-compatible workloads to run closer to systems of record. While hyperscalers use Arm to lower their own internal power costs and pass savings to cloud-native tenants, IBM is targeting the sovereign and air-gapped market."

  • Raspberry Pi 4 3GB Launches, Raspberry Pi Prices Go Up Again Due To RAM
    by BeauHD on 02/04/2026 at 7:00 pm

    AmiMoJo shares a report from Phoronix: Raspberry Pi prices are going up yet again due to the continued memory squeeze on the industry. To help offset the memory prices for some use-cases, Raspberry Pi also announced the introduction of the Raspberry Pi 4 3GB model at $83 to help fill the void between the 2GB and 4GB options. The 3GB Raspberry Pi 4 was announced at $83.75 USD for those not needing quite 4GB of RAM and looking to save some memory given the ongoing price increases. The Raspberry Pi 4 and Raspberry Pi 5 4GB models are seeing new $25 price increases, the 8GB models seeing $50 price increases, and the 16GB Raspberry Pi 5 is going up by $100. The Raspberry Pi 500+ is seeing a $150 price increase. The Raspberry Pi Compute Modules are also seeing increases from $11.25 to $100 USD. Read more of this story at Slashdot.
