  • Used EV Prices are Now Going Up in America
    by EditorDavid on 01/08/2026 at 4:00 pm

    Electric vehicles have historically been "notorious" for losing their resale value, reports CNBC. But this year prices for used EVs in the U.S. "are up 5.1% from January to June 2026, according to a Recurrent analysis published this month." The trend continued into the second half of the year: Prices are up 7% year to date through mid-July, it said. Recurrent compared EVs according to the same make and model year across 108 combinations and weighted price growth according to inventory volume. "Used EVs are appreciating, which almost never happens," according to an e-mailed Recurrent statement about the analysis. Other auto analysts found a similar trend... Price growth for used EVs has been broad-based, said Stephanie Valdez Streaty, the director of industry insights at Cox Automotive, a market research firm. Twenty-one of the 25 used EV models with the highest sales volume increased in price between January and June this year, she said... [T]he price growth for used EVs this year has been all the more surprising because it has happened despite a high supply of used EVs hitting the market — which, all else being equal, would generally cause prices to fall, experts said... There are several factors juicing consumer demand for used EVs, experts said. Among them are high gasoline prices due to the Iran war, which have pushed more consumers to consider fuel-efficient options, experts said... Overall affordability is another big factor, against a backdrop of inflation that has remained above policymakers' target of 2% for five or so years, auto experts said. The dynamic has pushed more consumers toward the used car market more broadly. Two interesting statistics from the article: "Used EV sales were up 20% in June versus a year earlier, while sales of new EVs were down about 28%, according to Cox Automotive data." New EVs accounted for 5.4% of total new-vehicle sales in June, while the market share for used EVs was just 2.4%, according to Cox Automotive data. Read more of this story at Slashdot.

  • Google Plans To Exempt Sanctioned Nations From Android Developer Verification
    by BeauHD on 01/08/2026 at 3:00 pm

    An anonymous reader quotes a report from Ars Technica: We are a month away from the initial rollout of Google's Android developer verification system, and the company contends this policy does not impinge on the platform's open nature. Still, the restrictions will be a big change, and there are still some unanswered questions. An issue that has come up repeatedly in the run-up to verification is what will happen to devs who can't verify because of where they live. It turns out that Google has a cryptic answer for that buried in an FAQ. Developer verification will soon block the installation of apps from unverified developers on any Android device running Google services, which is functionally all Android phones outside Russia and China. Developers who want to keep releasing software, even if it's not in the Play Store, have to provide Google with their ID and pay a small fee. But what if you're an Android developer living in a sanctioned nation? Currently, the U.S. sanction list includes Iran, Cuba, North Korea, and occupied areas of Ukraine. Given the current uncertain state of US foreign policy, that list could change in the future. Google doing any business with developers in those places is a thorny issue, and it seems like the company has decided to just leave them hanging. A rather lengthy FAQ a few levels deep on the Google developer site addresses various issues around dev verification. Smack in the middle is this: "How does this program impact developers in sanctioned countries? Devices in sanctioned countries will be excluded from Android developer verification checks. This allows any developer to continue distributing apps in these regions without verification, though users there won't benefit from the enhanced security benefits of the program." [...] A Google spokesperson has expanded on the FAQ and confirmed to Ars that people living in sanctioned nations will not be allowed to go through the verification process. That means they will not be able to effectively distribute software through any channel internationally. Today, someone making an app in, say, Cuba can distribute it freely around the world, as well as at home. Anyone can install it and see their work in action after tapping through a few sideloading alerts. In the coming months, that will no longer be the case. These unverified apps will only be easily installable in the sanctioned countries where verification doesn't exist. Read more of this story at Slashdot.

  • Drones Offer Alternative to Balloons For Weather Research
    by BeauHD on 01/08/2026 at 11:00 am

    The U.S. company Meteomatics has created an automated weather-monitoring system that uses drones to collect atmospheric data at multiple altitudes before returning to recharge and upload their findings. The so-called Meteobase, which consists of a base station on the ground with a drone that can be launched and recovered automatically, "is highly weather resistant and keeps the drone at a comfortable temperature," reports The Guardian. "It can send out one data-gathering mission a day, or multiple flights to monitor fog, icing, an advancing weather front, or other fast-changing conditions." The report says the reusable drones could offer a cheaper, more controllable alternative to helium weather balloons, especially for tracking rapidly changing conditions.

  • Drifting SpaceX Rocket Heading For Accidental Collision With the Moon
    by BeauHD on 01/08/2026 at 7:00 am

    "Space.com and The Guardian are reporting that the Falcon 9 upper stage leftover from the launch of the Firefly Blue Ghost-1 lander on Jan. 15, 2025 is due to impact the Moon on Aug. 5, 2026," writes longtime Slashdot reader fahrbot-bot. From a report: Onboard the same flight was the Hakuto-R Mission 2, called Resilience, a robotic lunar lander developed by the Japanese company ispace. According to a new study by an international team, the resulting impact plume may briefly be bright enough to see against the dark sky near the moon's edge. That means it might be visible to moongazers with sufficiently sensitive telescopes. This head-on collision of the errant stage is expected to occur near the Einstein and Bell craters near the western lunar limb. It may well be visible to ground and space-based assets. Using special physics simulations to model the impact, William Jo, a graduate research assistant at the University of Texas, Austin and colleagues predict the debris plume from the impact will have the central ejecta spike reaching roughly 47 miles to over 60 miles (75 kilometers to 100 kilometers) altitude. "Our calculations suggest the plume should be several orders of magnitude brighter than the dark-sky background for the first few minutes after impact," Jo told Space.com. "So the plume should be visible, though I'd stress this is a single nominal case. The real one will look different, and the numbers are on the optimistic side. But the point worth making is that the flash isn't really the story here." Jo emphasized that there's great slam-dunk science to be had. "Watching this one gives us a rare chance to open up ejecta-plume science and calibrate those models against a real event, which matters for every future thing we deliver to the moon," Jo said.

  • OpenAI Finds Evidence Other AI Agents Escaped Containment
    by BeauHD on 01/08/2026 at 3:30 am

    An anonymous reader quotes a report from Reuters: OpenAI has discovered other instances in which autonomous agents have escaped containment as the company expands its investigation of the hacking incident at tech firm Hugging Face that drew global attention this month, two people familiar with the matter said on Friday. The new breakouts were uncovered during the company's publicly announced investigation into how one of its agents escaped what was meant to be a contained testing environment this month, the two people said, and OpenAI is now looking into those instances as well. One of the sources said that the escapes were limited in nature and that none of the agents were thought to have left OpenAI's network. An OpenAI spokesperson referred to a statement issued by the company on Tuesday that said it was reviewing "broader activity from our models" in addition to the Hugging Face intrusion. The discovery of additional rogue behavior at OpenAI, even if limited in nature, could feed growing appetite for regulation coming out of the White House and elsewhere. The expanded investigation by OpenAI was launched shortly before its primary rival, Anthropic, disclosed that its models were also responsible for a series of break-ins that led to breaches at three other companies dating back to April, according to the two sources and a third source familiar with the matter. The recent discovery of other past breakouts at OpenAI has not previously been reported. AI safety experts said the new disclosures paint a portrait of a group of cutting-edge labs whose ability to develop dangerous autonomous hacking agents outstrips their ability to keep them under control. "We have a whole industry where the people designing, developing and putting out these tools aren't keeping up themselves to responsibly develop these things and keep them safe," said Maurice Chiodo, a mathematician who works at Cambridge University's Center for the Study of Existential Risk. Reuters could not establish exactly how many incidents OpenAI investigators found or the timings or circumstances under which they occurred. The three sources said OpenAI and outside experts were examining log data from earlier in the year in a bid to understand what took place. Read more of this story at Slashdot.

  • The Major Labels Propose Rules to Keep AI Slop Off the Charts
    by BeauHD on 31/07/2026 at 11:00 pm

    Major record labels including Universal, Sony, and Warner have proposed excluding AI-generated songs from official charts unless they are "substantially human made," properly labeled, legally produced, and free from manipulation concerns. The Verge reports: The proposal goes quite a bit further than a labeling proposal put forth by the RIAA, the International Federation of the Phonographic Industry (IFPI), SAG-AFTRA, and others. That would create a set of standardized labels for AI-generated and AI-assisted music. The labels' proposal would require songs be clearly labeled, but it would also keep them off international charts unless they met specific criteria, including being "substantially human made." To be eligible, the songs would also have to respect the terms of service of whatever AI service was used, the model would have to have the rights to any data it was trained on, and "not raise stream or chart manipulation concerns." What sort of concerns and what constitutes "substantially human made" are currently vague. Sony Music, UMG, and Mom+Pop Music did not immediately respond to a request for clarification. The IFPI has thrown its weight behind the labels' proposal, though no charting organization has signaled any immediate plan to adopt the rules [...]. Read more of this story at Slashdot.
