Submission + - Converting Semi Trailers into Plug-In Hybrids (ieee.org)

necro81 writes: There are several companies, such as Tesla, trying to make semi trucks fully electric. The capital cost for such a truck, and the MW-scale infrastructure to recharge it, may be a hard sell for some operators. IEEE Spectrum reports that some companies are instead adding batteries and an electric motor to the semi-trailers that trucks haul behind them.

The Nivalis Powered Trailer Kit centers on an electric axle...rated at 50 kilowatts peak, capable of both propulsion assistance and regenerative braking. That axle draws on a 60-kilowatt-hour, 400-volt lithium-ion battery pack charged from three sources: the axle itself during braking and deceleration, a full-rooftop array of photovoltaic panels generating up to 3.7 kilowatts-peak, and a 32-amp, three-phase AC grid connection available during parking stops.

This approach is more akin to a plug-in hybrid: the truck may still be diesel-powered, but the electric assist from the trailer allows the truck to run more efficiently. Replacing diesel with kWh can save operators money while also reducing emissions. This incremental approach may be more accessible and less capital-intensive than replacing the truck itself.

Trailer Dynamics’s modular system offers three configurations ranging from 187 to 551 kilowatt-hours.... The M300 version [a 300-kWh battery] adds approximately four tonnes to the trailer.... Trailer Dynamics argues the weight penalty is largely academic in practice, because more than 90 percent of trailer movements are constrained by cargo volume before they approach legal weight limits.

Trailer Dynamics prices its system between €145,000 and €195,000 and targets a payback period of no more than five years. Nivalis targets five to six years at current costs.... Until someone publishes a full year of results from a trailer running in normal commercial rotation, fleet operators cannot answer the two questions that actually drives adoption: What does this cost, and when does it pay back?

'Knockoff' Browser Extension Hides Sketchy Brands On Amazon (404media.co) 120

alternative_right shares a report from 404 Media: A software developer made a Chrome and Firefox extension called Knockoff that automatically hides, grays out, or filters products from sketchy brands on Amazon, which highlights just how many shady brands are on the platform and how commonly they show up on searches for basic items. In just a few minutes of using the extension, Knockoff dimmed product listings for screwdrivers made by "SUNHZMCKP," spoons made by "SACATR," and a lamp made by "ROTTOGOON."

In a tweet announcing the extension, developer Josh Pigford wrote "Sorry to brands like WNPETHOME, EHEYCIGA, YXYL, LU&MN, JOYIN, TOMY, GODONLIF, YOOJEE, LINGTENG, LANEIGE, VISCOO, BIODANCE, COOFANDY, BALENNZ, TOSY, and LUENX." The extension can also hide all sponsored product listings. The extension quickly went viral as a much-needed filter for people who still use Amazon and, for those who don't use Amazon because of its horrendous labor practices and other concerns, it is evidence of what an incredible wasteland the platform has become.

FCC To End Biden-Era Rule That Forces ISPs To List All Their Fees (arstechnica.com) 123

The FCC plans to roll back broadband label rules that require ISPs to itemize all passthrough fees. Under the proposal, providers could instead list a single "up to" amount for location-based charges. It would also allow ISPs to link to pricing labels rather than display them prominently, while eliminating machine-readable pricing files. Ars Technica reports: ISPs routinely advertise prices much lower than those actually charged to consumers on their monthly bills. One method of raising monthly bill prices above advertised rates is to tack on fees that, ISPs claim, are used to offset charges imposed by local governments. ISPs would be well within their rights to advertise accurate monthly prices and charge those exact prices on monthly bills. But because ISPs rarely do that, the FCC has required them to make specific price disclosures to consumers for the past decade. The Biden-era FCC updated the broadband-label rules to require that ISPs "itemize on the label (PDF) all discretionary monthly fees that the provider passes through to the consumer." The change drew protest from Comcast and other ISPs that complained bitterly about the complexity of listing all the hidden fees they had chosen to charge.

Under Chairman Brendan Carr, the Trump FCC has steadily whittled away at requirements imposed under Democrats. An order (PDF) released in draft form last week would eliminate the requirement to itemize passthrough fees and let ISPs list them in a single "up to" amount. The "up to" amount can include both government fees and fees charged by non-government entities such as owners of utility poles. "Rather than continuing to require providers to itemize 'passthrough fees' that can vary by location, we allow providers to display such fees in the aggregate, either as a maximum or 'up to' amount for the total fees applicable in any location where the service plan is offered, or as the exact total of such fees assessed in a particular location," the FCC draft order said.

The order to be voted on later this month includes a few other changes that will please ISPs and their lobby groups. ISPs will be allowed to provide links to price labels instead of displaying the full labels prominently on ordering pages and account portals, and will be allowed to stop making the price-label information available in machine-readable spreadsheets. The FCC is also relaxing the requirement that price information be available over the phone. The FCC said the change will "allow phone sales representatives to present label information conversationally, as a summary of key label fields, rather than require verbatim recitation."

The changes have been in the works since October 2025, when the FCC issued a Notice of Proposed Rulemaking to let the public submit comments on the proposals. The outcome of that process is the draft order, which will be voted on at the FCC's July 22 meeting and take effect 30 days after it is published in the Federal Register. There are many types of passthrough fees that ISPs will be able to stop listing individually and roll into the "up to" amount. The FCC defined the fees as follows, saying they include just about anything that isn't a tax [...]. Another planned change will eliminate a requirement that providers archive all labels for at least two years after a service plan is no longer available. The Utility Reform Network, an advocacy group, told the FCC that the archived labels provide crucial data about how prices and services change over time, and that machine-readable labels are important for affordability research and information accessibility.

Major Banks In Talks To Exploit Debit Card Loophole (msn.com) 52

JPMorgan, Bank of America, Wells Fargo, PNC, and other major banks have reportedly explored acquiring Fiserv's debit-card networks, STAR and Accel, in a move that could help them bypass federal caps on debit-card transaction fees. A law limits the fees big banks can charge merchants, but only if the transactions are routed through an outside network. There are no caps on these interchange fees over a bank-owned network, however. The Wall Street Journal reports: When Capital One Financial bought Discover Financial in a $50.6 billion deal, it got a network that cut out the need for a middleman in card transactions and allowed it to deal more directly with merchants. Now, big banks are looking on with envy because owning a network can mean exemption from a federal law that caps debit-card fees. Those fees collectively amount to billions of dollars each year across the industry, but banks have long complained the government-defined cap limits their ability to offer customers debit-card rewards and other services. Some have been exploring a small deal that could upend the rules, though they are worried about political backlash if they try.

Big banks including JPMorgan Chase, Bank of America, Wells Fargo and PNC Financial Services Group have in recent months held preliminary and tentative discussions about a deal to acquire a network owned by the financial-technology company Fiserv, according to people familiar with the matter. There is no certainty a deal will happen. Several of the banks that looked at the Fiserv network have already decided it would be unlikely for them to move forward, some of the people said. Some have privately expressed concern that such a deal could prompt backlash from lawmakers, regulators and merchants, the people added.

Microsoft Can Track Users Via a Windows Device ID (pcmag.com) 55

A criminal complaint against alleged Scattered Spider member Peter Stokes revealed that Microsoft can associate Windows activity with a persistent "Global Device ID," which investigators used to link his PC to online activity connected to a hack. While unique device IDs are common, the case has raised privacy concerns because the identifier can apparently persist across updates, has no simple opt-out, and may allow Microsoft to connect a Windows installation to activity on third-party services. PCMag reports: Last week, the U.S. announced it had extradited 19-year-old Peter Stokes from Europe for allegedly being a member of the notorious hacking group Scattered Spider. But the case stands out because Microsoft played a key role in linking Stokes to the suspected hacking crimes, according to an unsealed criminal complaint. Stokes allegedly hacked an unnamed luxury jewelry retailer in May 2025 while using a VPN. The 39-page criminal complaint shows the FBI used Microsoft records to discover that his IP address was associated with a Microsoft device identifier known as Global Device ID (GDID).

"According to a Microsoft representative, a Global Device Identifier in the Windows ecosystem is a persistent, device-level identifier designed to uniquely identify an installation of a Windows operating system on a device, either a physical device (e.g., a mobile phone or laptop) or virtual machine, across certain Microsoft services and scenarios," the complaint explains. The global device ID isn't exactly surprising, given that it's standard practice to assign a unique ID to each account or device so a tech provider can recognize and distinguish between them. But the complaint reveals Microsoft can associate the GDID with third-party services and the timing as well, giving Redmond a way to theoretically track a user's online activity. In other words, Redmond might be able to track the online activity of your Windows PC without third-party browser cookies.

Stokes was discovered exploiting a web development tool called ngrok to bypass the jewelry retailer's network defenses. The complaint says Microsoft had records showing that on May 12, 2025, at 19:21 UTC, the GDID associated with Stokes' computer "accessed, among other ngrok pages, 'https://dashboard[.]ngrok.com/signup,' the ngrok page to set up an ngrok account." The document adds that Microsoft records also showed the GDID accessing "multiple sites" from servers at Tzulo, a web hosting provider, to help pull off the hack. Hence, the fact that federal investigators used the Microsoft identifier to nab a suspected hacker is raising concerns that it could be abused for other surveillance purposes. "Microsoft Windows is surveillance software," cybersecurity expert Matthew Hickey alleged in a tweet.

Learning Another Language Appears To Slow Brain Aging By Up To 13 Years 100

A new study suggests multilingualism may slow brain aging, with bilingual people showing brains that appear about six years younger than monolingual speakers and people who speak four languages showing brains that appear up to 13 years younger. Researchers say earlier language learning and higher proficiency appear to strengthen the effect. The Guardian reports: Our brains are made up of billions of nerve cells that communicate with one another. But as we get older, the connectivity in our brains often deteriorates, causing memory and speed of thought to decline. While previous research had observed that people from European countries with greater language proficiency tended to age more slowly, this study measured the impact of speaking languages on individual brains. Scientists in Spain, Chile, Argentina and Dublin compared people living in the Basque region -- characterized by high levels of multilingualism -- who spoke Spanish, Basque, French and/or English.

To measure neurological age, the scientists used magnetoencephalography to measure the brain activity of 728 people with varying ages and levels of linguistic ability. They then used AI to process the results to calculate a normal level of brain connectivity at any given age. A second unrelated group of 144 people were then scanned and compared, comprising equal numbers of people speaking one, two, three or four languages.

Dr Lucia Amoruso, from the Basque Center on Cognition, Brain and Language in San Sebastian, said: "In simple terms, people who spoke more languages tended to have brains that looked younger than expected for their chronological age. The effect was not only related to the number of languages spoken. Higher language proficiency and earlier acquisition of a second language were also associated with more delayed brain ageing. This suggests that multilingual experience matters as a gradient: it is not simply about being bilingual or not, but about the depth and duration of language experience."

Research Universities Are Admitting Fewer PhDs, a Bad Sign For Science (nytimes.com) 149

An anonymous reader quotes a report from the New York Times: The number of students admitted to Ph.D. programs this fall dropped 15 percent from the previous year, according to data from over 50 top research universities, raising fears that the nation's capacity to produce new science could be diminished. The decline is driven, in part, by a chaotic and unpredictable federal funding environment under the Trump administration, as federal cuts are promised and then reversed, and budgets remain unclear.

A reduction in doctoral students could mean fewer scholars at universities to teach and mentor undergraduates. Higher education leaders also worry that, if the declines continue, there will be fewer researchers to power a rapidly evolving scientific work force. The data showing the decrease comes from 55 universities, all of them members of the Association of American Universities, an invitation-only organization that includes 69 of the most prestigious research institutions in the United States. The data collection was conducted by another group, the Association of American Universities Data Exchange.

Schools in A.A.U. confer half of the nation's research doctorates, according to the association. "We are at risk of losing a whole generation of new talent because of the reduction in the capacity to support those students," said Toby Smith, a senior vice president at the A.A.U. University leaders and research advocates cite many reasons for the declines in new doctoral students. Key federal agencies, such as the National Institutes of Health and the National Science Foundation, have been funding fewer research grants. The wealthiest institutions also face a new federal tax on their endowments.

But the most cited reason in interviews was the unreliable nature of federal funding under the Trump administration. The administration proposed major cuts to federal research agencies last year, but Congress restored the funding. It is again proposing big cuts. While Congress may again reverse the administration's proposed reductions, the uncertainty makes it hard for schools to make multiyear commitments to doctoral students. The administration also abruptly ended thousands of research grants last year, arguing that they did not align with the government's priorities. The administration restored many of the grants after judges deemed the eliminations illegal and arbitrary, but research advocates say the whiplash was damaging.

Small AI Models Gain Traction Around the World 104

locater16 shares a report from IEEE Spectrum: One morning in 2019, Adebayo Alonge was in a Cape Town hotel room, preparing to demonstrate his startup's AI answer to a serious problem in African health care: counterfeit medication, which kills thousands of people across the continent every year. The RxScanner is a handheld spectrometer that scans a pill with infrared light, then sends the item's molecular profile to an AI model equipped with a pharmaceutical database. In seconds, the AI identifies the medication from its molecular profile -- or reports that it's phony.

Pharmacies were using the system in more than a dozen countries, including Ghana, Kenya, Myanmar, and Alonge's native Nigeria. But that morning in South Africa, it didn't work. "I was shocked," Alonge says... So Alonge immediately asked his engineers to shrink the AI model down to a smaller, low-power, unconnected version that could run entirely on his Android phone. They produced it 2 hours later, and that saved the demo. More importantly, the work birthed a new version of his device, which can authenticate a pill in places without broadband, computers, or even reliable electricity. It also turned Alonge into an advocate for this kind of "small AI."
"The article goes on to detail other immediately useful 'small' AI applications without any subscription or billion dollar data centers needed," writes locator16. For example, Bala Murugan and colleagues at Vellore Institute of Technology in India developed a drone-based system that photographs cashew plants and identifies disease-indicating splotches on the plants. The key advantage is that all processing happens on the drone itself, so farmers do not need a computer, broadband connection, or cloud server access.

In a Uruguayan vineyard, researchers developed small-AI systems to identify ant infestations. The article doesn't go deep into the deployment details, but it presents this as another example of a narrow, localized model trained to recognize a specific agricultural threat. Small AI has also been used to detect the presence of malaria-carrying mosquitoes in multiple countries. This is especially useful in regions where public-health teams may lack reliable network access or expensive lab infrastructure, but still need fast, local detection.

In parts of Brazil without access to more complex medical equipment, researchers have used small AI to run electrocardiograms from an Arduino device. The article also describes Marcelo Jose Rovai's work on a TinyML model that generates electrocardiograms in a patient simulator lab. Rovai also describes a newer experiment using an Arduino UNO Q with a Qualcomm chipset. The device runs a language model locally, collects sensor data, and analyzes it to detect tiny pools of water where mosquitoes might breed -- while using only about 3 watts of power.

Supreme Court Allows Texas To Require Age Verification For Mobile Apps (cnn.com) 120

The Supreme Court allowed Texas to enforce a law requiring app stores to verify users' ages and obtain parental consent before minors can download apps. Tech industry groups argue the law broadly restricts young people's access to digital speech, but the court let a 5th Circuit order stand without explanation or noted dissents. CNN notes that the Supreme Court's decision "doesn't resolve the case but rather will allow Texas to enforce the law while the litigation continues to play out." From the report: "A minor child who downloads a software application from an app store agrees to contractual terms of service, including whether the child's location will be tracked, whether the child's privacy will be protected, whether information from the child's phone can be sold by the developer, and whether the child waives the right to sue," Texas told the Supreme Court in urging the court to allow its law to take effect.

But the Computer & Communications Industry Association, a trade group whose members include Apple and Google, said the law would effectively bar young people from accessing a wide range of content, "be it a book by Ernest Hemingway or J.K. Rowling, a Taylor Swift album, or a subscription to National Geographic." Allowing the law to take effect, the group said, would have "profound consequences for the protection of digital speech."

[...] In the new case, involving Texas' age verification for apps, a federal district court blocked the law's enforcement in December -- days before it was set to take effect. But a three-judge panel of the conservative 5th US Circuit Court of Appeals put that decision on hold in early June, allowing the state to enforce it. By declining to take up the emergency appeal from the computer and student groups, the Supreme Court has left the 5th Circuit's decision in place.

Submission + - Scientists Built Cancer Kill Switch That Turns On With Flash of Light (studyfinds.com)

fjo3 writes: Cancer has a dirty trick: it can put itself to sleep. When tumor cells slip into a kind of biological hibernation, they become hard to kill, shrugging off treatment and lying low until conditions improve, then waking up and bringing the disease back. For decades, researchers have struggled to shut down this hiding strategy without causing serious harm elsewhere in the body. A team in Switzerland has now built a molecule that flips on and off with flashes of light, giving scientists a precise new way to probe, and possibly disrupt, the way sleeping cancer cells hide.

Behind this cellular sleep state, at least in certain cancers, sits a protein called the glucocorticoid receptor, a sensor inside cells that reacts to stress hormones. When it switches on, it can push cancer cells, especially in some solid tumors such as lung cancer, into a drug-resistant, dormant state. The obvious fix would be to destroy the receptor outright, but there is a catch: the same receptor does important jobs all over the body, including calming inflammation. Removing it everywhere would cause real damage. What was needed was a way to hit the receptor inside a tumor and leave the rest of the body alone.

Hundreds Support Legal Defense for Engineer Charged with Destroying Flock Surveillance Cameras (futurism.com) 98

"Hundreds of freedom lovers are rallying behind a US Air Force engineer" who's been accused of damaging over a dozen AI-integrated surveillance cameras last year and even knocking down their poles. Long-time Slashdot reader schwit1 shares this article from Futurism: According to local channel WAVY, Virginia-based Air Force engineer and mechanic Jeffrey Sovern is facing 13 counts of destruction of property, as well as six counts of both petit larceny and possession of burglary tools related to the destruction of Flock license plate cameras... [Wavy reports the cameras were sometimes pointed in the wrong direction or thrown to the street.]

Armed with garbage bags, spray paint, and even chainsaws, a not insignificant number of privacy vigilantes have taken the fight to Flock, using any means to free their neighborhoods of the ominous surveillance poles. On a GoFundMe page to raise money for his legal defense, the 41-year-old Sovern explained that this kind of privacy-minded vandalism has far more support than would outwardly appear...

Sovern kicked off the campaign late in December of 2025, where he encouraged his supporters to "reach out to the local governments and demand that these systems are taken down." The Virginia resident initially set his funding goal to $8,500. As news of his case has spread across the web, the amount of support has far outpaced those already-hopeful aspirations. [Two hours ago the legal fund stood at $23,326 from over 680 donors].

Ask Slashdot: Which Apps Aren't Available on Linux? 242

Have you ever needed a Linux application which only exists in the Windows world? Long-time Slashdot reader BrendaEM writes: Windows does have a lot of useful app (but smaller than "power apps"). Some of these are closed source, some are open, but they're not all available in Linux yet.

My list would have to contain Gimp Tookit versions of: IrfanView image manager, which I think is unequaled in Linux (though it does work to some extent under Wine). I also miss the full version of 7-Zip, because of its better compression settings, which File-Roller does not provide, though the Linux port p7zip is available (though unnoticed by common distributions). Lastly, I think that Notepad++ would be a good addition to Linux.

That last one drew some pushback from long-time Slashdot reader jesco. "If there's one area where Linux shines, then it's the availability of high-quality text editors. Last time I looked Kate was still pretty nice, and there's Emacs, Vim and Neovim" if you're partial to command lines. But are there any daily-drive apps you still find yourself needing?

Hobbit-like Humans May Have Scavenged Komodo Dragons' Leftovers to Survive (cnn.com) 19

CNN reports: Prehistoric human relatives, nicknamed "hobbits" due to their short stature, may have been scavengers, rather than skilled hunters capable of taking down big game or building cooking fires, according to new research. The study adds to growing evidence that Homo floresiensis, which had a brain only slightly bigger than that of a chimpanzee, wasn't as advanced as scientists previously believed....

The researchers believe that much like how Komodo dragons hunt water buffaloes today, they were using their venomous bite to take down Stegodons — and after the scene was clear, Homo floresiensis swept in to cleave meat from what remained... The new study reinforces a long-held suspicion that Homo floresiensis is not a dwarfed form of Homo erectus but a descendant of a more primitive Homo habilis-like or Australopithecus-like form that arrived on the island more than1 million years ago, said Dr. Chris Stringer, a research leader specializing in human origins and paleoanthropology at London's Natural History Museum.
