  • Will Maryland's Utility Bills Increase $1.6B to Support Other States' Datacenters?
    by EditorDavid on 09/05/2026 at 10:34 pm

    To upgrade its grid for data centers, PJM Interconnection (which serves 13 states) plans to spend $22 billion — and charge nearly $2 billion of that to customers in Maryland, argues Maryland's Office of People's Counsel. The money "will be recovered in rates for decades" and "drive up Maryland customer bills by $1.6 billion over the next ten years alone," they said Friday, announcing an official complaint filed with America's Federal Energy Regulatory Commission. Extra demand is expected from Ohio, Pennsylvania, and Illinois "where demands driven by data centers are projected to grow substantially by 2036," they explain. But that means that Maryland customers "are subsidizing data center-driven transmission buildout by virtue of geographic proximity..." Tom's Hardware explains: That means an extra $823 million for residential (approx. $345 per customer), $146 million for commercial (approx. $673 per customer), and $629 million for industrial customers (approx. $15,074 per customer)... "Maryland customers have neither caused the need for these billions in new transmission projects nor will they meaningfully benefit from them," [according to Maryland People's Counsel David S. Lapp].... This is one of the biggest reasons why many AI hyperscalers are facing pushback from the communities where they intend to place their data centers. At the moment, around 69 jurisdictions have passed some sort of moratorium on projects like these, and a survey has shown that nearly half of Americans do not want a data center in their neighborhood. Debates around these projects are passionate, with a few cases turning violent and even resulting in shootings (thankfully, without any casualties), especially as many feel that the construction of these power-hungry assets is threatening their lifestyles and quality of life.

  • Rush Rescue Mission for NASA's $500M Space Telescope Passes Key Milestone
    by EditorDavid on 09/05/2026 at 9:34 pm

    NASA's $500 million Neil Gehrels Swift space observatory was launched in 2004. But it's now "at risk of falling back through the atmosphere and burning up without intervention," reports Spaceflight Now. Fortunately, a mission to prevent that "just passed a notable prelaunch testing milestone." On Friday, NASA announced that the Link spacecraft, manufactured by Katalyst Space Technologies to intervene before Swift's fate is sealed, completed its slate of environmental testing at the agency's Goddard Space Flight Center in Greenbelt, Maryland... "Swift will likely re-enter the atmosphere sometime later this year if we don't attempt to lift it to a higher altitude, [said John Van Eepoel, Swift's mission director at NASA Goddard, in a NASA press release]. "Katalyst has gotten to this point in just eight months, and we're glad they were able to use NASA's facilities to test Link and draw on our expertise to help tackle questions that popped up along the way...." "Given how quickly Swift's orbit is decaying, we are in a race against the clock, but by leveraging commercial technologies that are already in development, we are meeting this challenge head-on," said Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters, at the time... Attempting an orbit boost is both more affordable than replacing Swift's capabilities with a new mission, and beneficial to the nation — expanding the use of satellite servicing to a new and broader class of spacecraft...." Swift is in an orbit inclined 20.6 degrees from the equator, which is why Katalyst selected Northrop Grumman's Pegasus XL air-launched rocket in November to fly the mission. "The versatility offered by Pegasus' unique air-launch capability provides customers with a space launch solution that can be rapidly deployed anywhere on Earth to reach any orbit," said Kurt Eberly, Director of Space Launch for Northrop Grumman. The mission is set to launch in June. Read more of this story at Slashdot.

  • The Trump Phone Either Is Or Isn't Closer To Delivery
    by EditorDavid on 09/05/2026 at 8:34 pm

    September 2025? January 2026? Delivery dates keep slipping for the Trump Organization's "Trump Phone" — a gold-coloured Android smartphone priced at $499 (£370). But in March the Verge spotted signs the phone was moving forward: FCC listings for a smartphone with the trade name "T1" show that it was tested late last year, and granted certification by the FCC in January... [T]he phone was submitted for testing by another company entirely: Smart Gadgets Global, LLC... Smart Gadgets Global's website promises "Top Quality Electronics created for 'YOUR' customer!" But in April the Trump phone revised its "Terms and Conditions" for preorders. The new language? A preorder deposit provides only a conditional opportunity if Trump Mobile later elects, in its sole discretion, to offer the Device for sale. A deposit is not a purchase, does not constitute acceptance of an order, does not create a contract for sale, does not transfer ownership or title interest, does not allocate or reserve specific inventory, and does not guarantee that a Device will be produced or made available for purchase.... Estimated ship dates, launch timelines, or anticipated production schedule are non-binding estimates only. Trump Mobile does not guarantee that: the Device will be commercially released... Trump Mobile will not be responsible for delay, modification, or failure to release a Device due to causes beyond its reasonable control, including but not limited to regulatory review, carrier certification delays, component shortages, labor disruptions, governmental orders, acts of God, transportation interruptions, or third-party supplier failures... If Trump Mobile cancels or discontinues the Device offering prior to sale, Trump Mobile will issue a full refund of the deposit amount paid... If Trump Mobile cancels, delays, or does not release the Device, your sole and exclusive remedy is a full refund of the deposit amount actually paid, and you waive any claim for equitable, injunctive, or specific performance relief relating to preorder priority or Device allocation. There was an unconfirmed report on social media that the updated Terms were also emailed to customers (cited by the International Business Times). And the new language also hedges that for the gold T1 phone, "Images, prototypes, beta demonstrations, and marketing renderings are illustrative only and may not reflect final production units...." But then eight days ago The Verge reported that phone "has just passed another milestone on its slow road to release," described as "a requirement for any phone launching in the US..." "The phone has received the little-known PTCRB certification, a first step toward being certified to work on major networks and be issued with IMEI numbers." [A]t least, I think it's been certified. What's actually been certified by the PTCRB is the SGG-06, a smartphone from Smart Gadgets Global, LLC, with support for 5G, 4G, 3G, and 2G networks. Read more of this story at Slashdot.

  • Plant Seeds Do Something Incredible When the Sound of Rain Strikes
    by EditorDavid on 09/05/2026 at 7:34 pm

    "Plant seeds can sense the vibrations generated by falling raindrops," reports ScienceAlert, "and respond by waking from their state of dormancy to welcome the water, new research shows.... to germinate in 'anticipation' of the coming deluge." The finding, discovered by MIT mechanical engineers Nicholas Makris and Cadine Navarro, offers the first direct evidence that seeds and seedlings can sense and respond to sounds in nature... "The energy of the rain sound is enough to accelerate a seed's growth," [explains Markis]. Plants don't have the same aural equipment we do to actually hear sounds, of course. But the study suggests that seeds respond to the same vibrations that can produce a sound experience in our human ears. Across a series of experiments, the researchers submerged nearly 8,000 rice seeds in shallow tubs of water, at a depth of around 3 centimeters (1 inch), and exposed some of them to falling water drops over periods of six days... A hydrophone recorded the acoustic vibrations produced by the drops, confirming that the experiment mimicked the vibrations produced by actual raindrops falling in nature — such as the driving downpours that can sometimes pelt Massachusetts' puddles, ponds, and wetlands... In their study, the researchers observed that seeds exposed to the falling drops germinated up to around 37% faster, compared with seeds that did not receive the simulated rainstorm treatment but were housed in otherwise identical conditions.

  • Cisco Releases Open-Source 'DNA Test for AI Models'
    by EditorDavid on 09/05/2026 at 6:34 pm

    Cisco has released an open-source tool "to trace the origins of AI models," reports SC World, "and compare model similarities for great visibility into the AI supply chain." [Cisco's Model Provenance Kit] is a Python toolkit and command-line interface (CLI) that looks at signals such as metadata and weights to create a "fingerprint" for AI models that can then be compared to other model fingerprints to determine potential shared origins. "Think of Model Provenance Kit as a DNA test for AI models," Cisco researchers wrote. "[...] Much like a DNA test reveals biological origins, the Model Provenance Kit examines both metadata and the actual learned parameters of a model (like a unique genome that comprises a model), to assess whether models share a common origin and identify signs of modification." The tool aims to address gaps in visibility into the AI model supply chain. For example, many organizations utilize open-source models from repositories like HuggingFace, where models could potentially be uploaded with incomplete or deceptive documentation. The Model Provenance Kit provides a way for organizations to verify claims about a model's origins, such as claims that a model is trained from scratch, when in reality it may be copied from another model, Cisco said. This may put organizations at risk of using models with unknown biases, vulnerabilities or manipulations and make it more difficult to resolve any incidents that arise from these risks.

  • Social Media Sites Got Information from Ad Trackers on US State Health Insurance Sites
    by EditorDavid on 09/05/2026 at 5:34 pm

    All 20 of America's state-run healthcare marketplace sites "include advertising trackers that share information with Big Tech companies," reports Gizmodo, citing a report from Bloomberg: Per the report, seven million Americans bought their health insurance through state exchanges in 2026, and many of them may have had personal information shared with companies, including Meta, TikTok, Snap, Google, Nextdoor, and LinkedIn, among others. Some of the data collected and shared with those companies included ZIP codes, a person's sex and citizenship status, and race. In addition to potentially sensitive biographical details about a person, the trackers also may reveal additional details about their life based on the sites they visit. For instance, Bloomberg found trackers on Medicaid-related web pages in Rhode Island, which could reveal information about a person's financial status and need for assistance. In Maryland, a Spanish-language page titled "Good News for Noncitizen Pregnant Marylanders" and a page designed to help DACA recipients navigate their healthcare options were found to be transmitting data to Big Tech firms... Per Bloomberg, several states have already removed some trackers from their exchange websites following the report. Thanks to Slashdot reader JoeyRox for sharing the news.
