A new study warns that glaciers in the European Alps will hit their peak extinction rate within eight years, with global glacier loss accelerating toward thousands per year unless emissions are rapidly cut. "Glaciers in the western US and Canada are forecast to reach their peak year of loss less than a decade later, with more than 800 disappearing each year by then," adds the Guardian. From the report: About 200,000 glaciers remain worldwide, with about 750 disappearing each year. However, the research indicates this pace will accelerate rapidly as emissions from burning fossil fuels continue to be released into the atmosphere. Current climate action plans from governments are forecast to push global temperatures to about 2.7C above preindustrial levels, supercharging extreme weather. Under this scenario, glacier losses would peak at about 3,000 a year in 2040 and plateau at that rate until 2060. By the end of the century, 80% of today's glaciers will have gone. By contrast, rapid cuts to carbon emissions to keep global temperature rise to 1.5C would cap annual losses at about 2,000 a year in 2040, after which the rate would decline. [...]
The new study, published in Nature Climate Change, analyzed more than 200,000 glaciers from a database of outlines derived from satellite images. The researchers used three global glacier models to assess their fate under different heating scenarios. Regions with the smallest and fastest-melting glaciers were found to be the most vulnerable. The study estimates the 3,200 glaciers in central Europe would shrink by 87% by 2100 -- even if global temperature rise is limited to 1.5C, rising to 97% under 2.7C of heating.
In the western US and Canada, including Alaska, about 70% of today's 45,000 glaciers are projected to vanish under 1.5C of heating, and more than 90% under 2.7C. The Caucasus and southern Andes are also expected to face devastating losses. Larger glaciers take longer to melt, with those in Greenland reaching their peak extinction rate in about 2063 -- losing 40% by 2100 under 1.5C of heating and 59% under 2.7C. However, the melting is forecast to continue beyond 2100. The researchers said the peak loss dates represent more than a numerical milestone. "They mark turning points with profound implications for ecosystems, water resources and cultural heritage," they wrote. "[It is] a human story of vanishing landscapes, fading traditions and disrupted daily routines."

An anonymous reader quotes a report from Ars Technica: Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years following more than a decade of devastating hacks that exploited it and recently faced blistering criticism from a prominent US senator. When the software maker rolled out Active Directory in 2000, it made RC4 a sole means of securing the Windows component, which administrators use to configure and provision fellow administrator and user accounts inside large organizations. RC4, short for Rivist Cipher 4, is a nod to mathematician and cryptographer Ron Rivest of RSA Security, who developed the stream cipher in 1987. Within days of the trade-secret-protected algorithm being leaked in 1994, a researcher demonstrated a cryptographic attack that significantly weakened the security it had been believed to provide. Despite the known susceptibility, RC4 remained a staple in encryption protocols, including SSL and its successor TLS, until about a decade ago. [...]
Last week, Microsoft said it was finally deprecating RC4 and cited its susceptibility to Kerberoasting, the form of attack, known since 2014, that was the root cause of the initial intrusion into Ascension's network. "By mid-2026, we will be updating domain controller defaults for the Kerberos Key Distribution Center (KDC) on Windows Server 2008 and later to only allow AES-SHA1 encryption," Matthew Palko, a Microsoft principal program manager, wrote. "RC4 will be disabled by default and only used if a domain administrator explicitly configures an account or the KDC to use it." [...] Following next year's change, RC4 authentication will no longer function unless administrators perform the extra work to allow it. In the meantime, Palko said, it's crucial that admins identify any systems inside their networks that rely on the cipher. Despite the known vulnerabilities, RC4 remains the sole means of some third-party legacy systems for authenticating to Windows networks. These systems can often go overlooked in networks even though they are required for crucial functions.
To streamline the identification of such systems, Microsoft is making several tools available. One is an update to KDC logs that will track both requests and responses that systems make using RC4 when performing requests through Kerberos. Kerberos is an industry-wide authentication protocol for verifying the identities of users and services over a non-secure network. It's the sole means for mutual authentication to Active Directory, which hackers attacking Windows networks widely consider a Holy Grail because of the control they gain once it has been compromised. Microsoft is also introducing new PowerShell scripts to sift through security event logs to more easily pinpoint problematic RC4 usage. Microsoft said it has steadily worked over the past decade to deprecate RC4, but that the task wasn't easy. "The problem though is that it's hard to kill off a cryptographic algorithm that is present in every OS that's shipped for the last 25 years and was the default algorithm for so long, Steve Syfuhs, who runs Microsoft's Windows Authentication team, wrote on Bluesky. "See," he continued, "the problem is not that the algorithm exists. The problem is how the algorithm is chosen, and the rules governing that spanned 20 years of code changes."

Once a star of the self-driving hype cycle, lidar maker Luminar has filed for bankruptcy amid legal turmoil, layoffs, and a cooling autonomous-vehicle market. It plans to sell off its assets before shutting down entirely. The Verge reports: As part of its bankruptcy, Luminar is seeking permission to sell both its lidar and semiconductor businesses, the latter of which it has already agreed to sell to Quantum Computing for $110 million. The company plans to continue to operate during the bankruptcy proceedings "to minimize disruptions and maintain delivery of its LiDAR hardware and software." That said, Luminar will cease to exist once the process is complete. "As we navigate this process, our top priority is to continue delivering the same quality, reliability and service our customers have come to expect from us," CEO Paul Ricci said in a statement.
After launching in 2017, Luminar muscled its way to the front of the autonomous vehicle industry as a top maker of lidar systems, a key technology that driverless cars use to sense the shapes and distances of objects around them. Luminar has sold sensors to Mercedes-Benz, Volvo, Audi, Toyota Research Institute, Caterpillar, and even Tesla, which has dismissed lidar sensors in favor of traditional cameras. The company was valued at nearly $3 billion when it went public through a reverse merger with a SPAC in 2020.

A critical React vulnerability (CVE-2025-55182) is being actively exploited at scale by Chinese, Iranian, North Korean, and criminal groups to gain remote code execution, deploy backdoors, and mine crypto. The Register reports: React maintainers disclosed the critical bug on December 3, and exploitation began almost immediately. According to Amazon's threat intel team, Chinese government crews, including Earth Lamia and Jackpot Panda, started battering the security hole within hours of its disclosure. Palo Alto Networks' Unit 42 responders have put the victim count at more than 50 organizations across multiple sectors, with attackers from North Korea also abusing the flaw.
Google, in a late Friday report, said at least five other suspected PRC spy groups also exploited React2Shell, along with criminals who deployed XMRig for illicit cryptocurrency mining, and "Iran-nexus actors," although the report doesn't provide any additional details about who the Iran-linked groups are and what they are doing after exploitation. "GTIG has also observed numerous discussions regarding CVE-2025-55182 in underground forums, including threads in which threat actors have shared links to scanning tools, proof-of-concept (PoC) code, and their experiences using these tools," the researchers wrote.

Merriam-Webster crowned "slop" its 2025 Word of the Year, reflecting growing public awareness and and fatigue around low-quality, AI-generated content flooding the internet. "It's such an illustrative word," said Greg Barlow, Merriam-Webster's president. "It's part of a transformative technology, AI, and it's something that people have found fascinating, annoying and a little bit ridiculous." The Associated Press reports: "Slop" was first used in the 1700s to mean soft mud, but it evolved more generally to mean something of little value. The definition has since expanded to mean "digital content of low quality that is produced usually in quantity by means of artificial intelligence." In other words, "you know, absurd videos, weird advertising images, cheesy propaganda, fake news that looks real, junky AI-written digital books," Barlow said. "Words like 'ubiquitous,' 'paradigm,' 'albeit,' 'irregardless,' these are always top lookups because they're words that are on the edge of our lexicon," Barlow said. "'Irregardless' is a word in the dictionary for one reason: It's used. It's been used for decades to mean 'regardless.'"
