Fungi are living below your feet. Roughly 110 quadrillion kilometers of living fungal threads are woven through the world’s soils. Stretched end-to-end they would cover a distance nearly a billion times that from Earth to the sun. Now, scientists have mapped where those networks are, how dense they are, and what threatens them. Last year, researchers published global analyses in Nature about the diversity patterns of underground mycorrhizal fungal communities along with the Underground Atlas to help decision makers visualize where to prioritize conservation. Now, they ask the question: How much fungal infrastructure exists, and where? A new study published in Science by researchers with the Society for the Protection of Underground Networks (SPUN) and collaborators produced the first global maps of arbuscular mycorrhizal (AM) fungal network density and biomass. “There could be up to 10 meters (32 feet) of mycorrhizal network in just a teaspoon of soil,” lead author Justin Stewart of SPUN said in a press statement. Nearly all land plants live in partnership with arbuscular mycorrhizal fungi. The fungi exchange water and nutrients for carbon made from sunlight. These underground networks act as a living circulatory system for the planet, and the new study found they move an estimated 4 billion tons of CO2 equivalent into soils annually, roughly 11% of global human-related emissions. To build the density maps, the team drew on data from more than 16,000 soil cores collected across nine biomes referenced in 322 published studies. They developed machine-learning models to predict network density…This article was originally published on Mongabay
Google is removing Chrome's last remaining workarounds for Manifest V2 extensions, effectively ending support for legacy ad blockers such as the original uBlock Origin. 9to5Google reports: CyberNews points out a Chromium commit that removes support for the "kExtensionManifestV2Disabled" flag, which is referred to as "dead code" seeing as Chrome no longer supports Manifest V2 extensions. This removal acts as the final stop for many Manifest V2-based ad blocker extensions that were still in use today -- the flag was effectively a loophole to continue using these extensions.
A Googler on the commit explains: "MV2 extensions are no longer allowed in any supported version of Chrome, and we are removing support for them and the associated functionality. We won't be able to provide / maintain this functionality indefinitely due to the complexity and tech debt, as well as the security risks it entails (we've actually found a number of bugs that are specific to MV2 lately). Of course, other browsers can continue supporting these if they so desire."
This will also impact other Chromium-based browsers, though the comment notes that "other browsers can continue supporting these if they so desire." Neowin points out that Microsoft Edge and Opera are likely to follow suit. Chrome 150, set to be released later this month, will remove this flag, while other leftover bits of Manifest V2 will be removed in the v151 release.

An anonymous reader quotes a report from Ars Technica: A decade ago, AMD added a protection to its high-end CPUs to protect them against cold boot attacks and other types of physical exploits that siphon sensitive data out of the connected memory chips. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to physical attackers. Over time, AMD added TSME to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips have gotten used to the added security. Recently and without warning or notice, this lower-end line of AMD chips suddenly dropped the protection, and did so in a way that was impossible to detect on Windows machines and required a fair amount of technical work when using Linux.
AMD has yet to say why TSME worked on these CPUs, or even to confirm the change. AMD declined to answer questions sent by email other than to say TSME "is a security feature only applied to PRO CPUs as part of AMD PRO Technologies." The statement is the first known time the chipmaker has explicitly made this restriction public. [...] There's no indication that AMD ever advertised or marketed TSME as being available in consumer CPUs. AMD has long said that a related memory protection, Secure Memory Encryption (SME), is available only in the Pro and Epyc CPU tiers. SME is OS-managed. It uses a single key and allows the OS to selectively encrypt individual memory pages. TSME is firmware-managed. It encrypts all RAM with no OS involvement. When active, it provides protection against physical attacks, including cold boot exploits, DRAM interface snooping, and memory module removal. It activates silently when enabled in the BIOS, making it the more practically useful of the two protections. Ben Kilpatrick, a self-described "privacy-conscious Linux hobbyist," discovered that TSME had stopped working on his consumer Ryzen processor despite remaining enabled in the BIOS. He spent months investigating, persuaded MSI engineers to test multiple CPUs, motherboards, and firmware versions, and filed a public AMD bug report that traced the change to newer AGESA firmware apparently disabling TSME on consumer chips while retaining it on Pro and EPYC models.
"AMD engineers' comments, such as those mentioned above, and the years of TSME working just fine in the lower-cost tier processors, have understandably conditioned Kilpatrick and other users to reasonably regard it as an expected part of the chip package," reports Ars Technica. "AMD quietly removing it and providing no acknowledgment or explanation strikes these users as something of a betrayal."
Joe Fitzgerald, an expert in silicon-level security, said in an interview: "They could have not realized they did it leading to their cagey responses, or they could have done it intentionally and tried to get away with it, leading to the same cagey responses. But I really feel like an explanation should be in order, even if it was 'TSME was never supposed to be supported. We did ship some firmwares that erroneously enabled it, but you shouldn't use them since we can't guarantee it'll work properly.'"
SEATTLE (AP) — Lawmakers are demanding the National Science Foundation stop dismantling the Ocean Observatories Initiative, a $386 million ocean monitoring network being wound down under President Donald Trump’s administration. House Democrats on two committees call the action illegal. Democratic Sen. Jeff Merkley says he’s drafting legislation to freeze the removal of instruments until a full scientific review is completed. The National Science Foundation directed the removal of most of the system’s instruments from waters off Oregon, Washington, Alaska, North Carolina and Greenland by 2027. Monday’s pushback against the Republican administration’s actions comes as scientists are set to remove instruments from the Pacific and as an El Niño event is predicted to arrive this summer.

Longtime Slashdot reader necro81 writes: The heavily promoted, $499 T1 "Trump Phone" was originally said to be "Made in the USA" and ship in September 2025. Later, that was downgraded to "Assembled in the USA." Given the Trump Organization's lack of engineering or supply chain expertise, many assumed the "T1" would just be a private-label phone made by someone else. After a number of delays, the first phones are finally shipping.
iFixit has performed a teardown and concluded that the T1 is a just gold-painted 2024 HTC U24 Pro -- a device from a Taiwanese company, probably using mainland China design and supply chains. In collaboration with NBC News, the iFixit team examined both phones using CT scans, side-by-side teardowns, and even reassembled a working T1 using a U24 Pro main board. As for "assembled in the USA," that may be true, in the same sense that your phone's repairman can "assemble" a phone from a handful of subassemblies sourced from someone else. Or it may have been assembled in Guangdong, China like the other U24 Pros.
iFixit sums it up: "What you have is not an 'American-Proud Design,' but a phone designed in China, made in China, with the vast majority of parts sourced from China. I'm failing to find any stirring of American pride within me. I've certainly felt it before, so I can confirm that it is absent at this time." Quinn Nelson of Snazzy Labs on YouTube also published a comprehensive video of his experience ordering, unboxing, and tearing down the phone. "From pre-order emails landing in Gmail spam thanks to botched DMARC records, to paying for the $47.45 Trump Mobile 47 Plan over the phone, the entire buying experience was a disaster worthy of its own review," writes Nelson.
Longtime Slashdot reader schwit1 shares a report from NBC News: British Prime Minister Keir Starmer has announced a sweeping ban on social media use for those under 16, joining other countries around the world seeking to protect children online. "It's a big step for our country," Starmer said in a recorded video message released Monday. "Social media is making our children unhappy and unsafe, and as a parent, as much as a Prime Minister, I just can't let that go on anymore," he added.
The ban will include social platforms like Snapchat, TikTok, YouTube, Instagram, Facebook and X, while there is no intention for messaging services like WhatsApp and Signal to be included, the government said in a release. [...] Starmer's government called Monday's announcement a "landmark" move, saying the new measures would be brought to Parliament before Christmas, with protections expected to come into force next spring. Beyond the blanket social media ban, the restrictions will also include blocks on functions such as livestreaming and stranger communication with children for under-16s, it added. "It's not an easy thing to do. I'll be honest about that," Starmer said. "We haven't rushed into it. We've looked carefully at the evidence, and we'll have to adapt our approach as technology changes, learn from other countries which are taking similar steps."
He went on to say that it will face resistance from some of the most powerful companies in the world. "But we will take them on, and we will win, because the need for action could not be any clearer."
Fox is buying Roku for $22 billion, combining Fox's sports, news, entertainment, Tubi, and Fox One offerings with a streaming platform that reaches about 100 million people. The companies say the merger would create the "third-largest player in US television by share of viewing," while Fox insists Roku will remain open to competing apps after the deal closes. CNN reports: Fox has dabbled in streaming over the past few years -- finally launching its Fox One competitor last August -- but has lacked a serious streaming business with the ability to compete in a space dominated by YouTube, Netflix, Amazon, Disney+, HBO Max, Paramount+ and Peacock. With CNN parent company Warner Bros. Discovery receiving initial US regulatory approval to combine with Paramount, Fox's purchase of Roku became more urgent. [...] The deal is expected to close in the first half of 2027 with the companies forecasting $400 million in savings. "This is a defining moment for Fox, and a natural extension of the deliberate and focused strategy we have been executing for nearly a decade," said Fox CEO Lachlan Murdoch. "Today, we take the next step: bringing together the most valuable live content portfolio in video consumption with the preeminent streaming platform through which America watches it."
Murdoch said Roku will continue to offer competing apps. "It's essential that Roku remain open and partner-friendly business. We don't see that changing at all."
