  • Amazon's Drones Will Soon Deliver to Nearly 500 US Cities and Towns
    by BeauHD on 19/08/2026 at 9:00 pm

    Amazon says its Prime Air drone delivery service will expand sixfold to nearly 500 U.S. cities and towns by the end of 2026, including metro areas around Chicago, Syracuse, Cleveland, Atlanta, and Boise. According to Amazon Prime Air vice president David Carbon, the service has already delivered "hundreds of thousands of packages to customers" this year, typically within about an hour. The Verge reports: These will join 11 locations across the US where Amazon already offers drone deliveries, with each Prime Air site serving an area of approximately 175 square miles. The service aims to quickly deliver packages of up to 5 pounds or less [...]. Amazon reiterated its drone safety features alongside these expansion plans, including Prime Air's "industry-leading Detect-and-Avoid system." That's likely an attempt to minimize any concerns raised by the communities where the service is expanding, given these drones have already been scrutinized for crashing into cranes, internet cables, gardens, and an apartment building.

  • Music Publisher Round Hill Files $1 Billion Copyright Infringement Suits Against Suno, Anthropic
    by BeauHD on 19/08/2026 at 8:00 pm

    Independent music publisher Round Hill is suing Suno and Anthropic for allegedly using hundreds of copyrighted songs without permission to train their AI systems. The company says potential damages could exceed $1 billion, arguing there is "nothing fair" about building multibillion-dollar AI businesses on copyrighted material while rights holders receive nothing. From The Hollywood Reporter: Round Hill is a prominent music publisher whose copyrights include the Goo Goo Dolls' "Iris," Bonnie Tyler's "Total Eclipse of the Heart," the Kinks' "Lola" and Dio's "Holy Diver." The company provided a list of 500 songs that the defendants had infringed upon. Round Hill said in the suits that the company plans to "amend to list potentially ten thousand or more of their musical compositions," with those damages potentially exceeding $1 billion. "While in other cases for copyright infringement, Defendant has waxed poetic about the necessity of progress and AI's value to society, there is simply no reason -- other than rote expediency -- to have that progress come at the cost of copyrights holders," prominent music attorney Richard Busch, representing Round Hill, wrote in the suits. Round Hill further argued that the latter "'expediency' arguments completely falter" when taking into account Suno and Anthropic's significant cash valuations they've earned while "exploiting illicit copies of copyrighted works, including the Round Hill Works." "There is simply nothing fair about a company using theft to build for purely commercial purposes a multi-billion dollar business while those from which they steal receive nothing," Round Hill said. Suno also faces a lawsuit from Universal Music Group and Sony Music Group. Read more of this story at Slashdot.

  • CISA: Medusa Ransomware Hit Over 500 Critical Infrastructure Orgs
    by BeauHD on 19/08/2026 at 7:00 pm

    CISA says the Medusa ransomware operation has breached more than 500 U.S. critical infrastructure organizations since 2021, up from more than 300 reported last year. The group has targeted healthcare, government, defense, manufacturing, IT and financial organizations, evolving into a ransomware-as-a-service operation that recruits initial-access brokers and uses stolen data to pressure victims into paying. BleepingComputer reports: The three federal agencies recommended that network defenders secure their networks against the ransomware group's attacks by mitigating security vulnerabilities to protect operating systems, software, and firmware from exploitation attempts. Security teams are also advised to segment networks to block lateral movement after compromise and to block access from untrusted origins to remote services on internal systems. [...] "Medusa developers typically recruit initial access brokers (IABs) in cybercriminal forums and marketplaces to obtain initial access to potential victims," the advisory says. "Potential payments between $100 USD and $1 million USD are offered to these affiliates with the opportunity to work exclusively for Medusa." Read more of this story at Slashdot.

  • Moderna, Merck Say mRNA Vaccine Prevents Melanoma From Returning
    by BeauHD on 19/08/2026 at 6:00 pm

    Moderna and Merck say their personalized mRNA melanoma vaccine significantly reduced both cancer recurrence and spread in a late-stage trial. The treatment could reach patients as soon as next year if regulators approve it. Reuters reports: Moderna developed the vaccine with Merck and tested it together with immunotherapy drug Keytruda, a widely used treatment for melanoma. [...] This is the first positive late-stage trial result for an mRNA cancer vaccine, which trains a patient's immune system to fight tumors by targeting specific mutations in those cells and the first such study to show that adding a treatment to Keytruda worked better than that therapy alone. Similar approaches are being tested against lung, breast and pancreatic cancers. [...] The cancer treatment combines Merck's Keytruda with a made-to-order mRNA vaccine from Moderna that is based on an analysis of mutations found in the patients' own tumors. The trial enrolled 1,137 high-risk patients with stage IIB-IV melanoma that had been surgically removed. Volunteers were randomized to receive up to nine doses of Keytruda plus the personalized vaccine or Keytruda alone for about one year. The companies said no new safety signals have emerged in the trial. In January, the companies announced results of a mid-stage trial of the treatment showing that it reduced the risk of recurrence or death by 49% after five years. Karen Knudsen, CEO of the Parker Institute for Cancer Immunotherapy, said the Moderna results could signal a new era for treating solid-tumor cancers. "The positive hit here leads us into truly this next phase in immunotherapy," Knudsen said. "This is an auspicious start -- this is where things begin." Moderna shares more than doubled on the news, adding about $30 billion to its market value. Read more of this story at Slashdot.

  • X's Algorithm Feeds Off Ragebait and Impacts Democrats More, Study Finds
    by BeauHD on 19/08/2026 at 5:00 pm

    An anonymous reader quotes a report from 404 Media: X's algorithm learns what you hate and shows you more of it, according to a new study just published in the Proceedings of the National Academy of Sciences (PNAS). The paper, titled Value misalignment of X's feed algorithm is a reflection of value tensions in engagement, found that the site's algorithm prioritized engagement above all else when it generated a user's For You Page. It also showed that X serves more ragebait to people who say they are Democrats, although the exact reason for that is unclear. "In 2026 that's maybe not the most surprising headline ever," Ziv Epstein, a postdoctoral researcher at Stanford University, and co-author of the paper, told 404 Media. "So we actually dug in a little deeper to figure out why this is actually happening, and it turns out that X's feed algorithm, like a lot of these social media algorithms, is optimized for engagement [but] it turns out that not all types of engagement are considered equally." The researchers found that X's algorithm can push users toward content that conflicts with their stated values, especially when they reply to posts that anger or provoke them. Although replies accounted for just 6.8% of interactions, they appeared to carry disproportionate weight: "It's this feedback loop of outrage baiting. The algorithm learns that you get outraged and then continues to serve more content in that direction," said Epstein. It's unclear why X seems to serve ragebait to Democrats more often than Republicans. 404 Media speculates that it may be because there's more rightwing content on X overall or that Democrats tend to engage with posts they disagree with more often. "There might be some kind of differential effects on information diets there, or it might be something more psychological about how different you know partisan identities are triggering different kinds of actions and reactions, but ultimately I don't want to speculate too much," said Epstein. X's former product chief Nikita Bier confirmed that the site had been set to favor replies. "This is no longer true," Bier said in a post on X. "The largest contributor of seeing ragebait was the reply predictor and we were aware that angry replies were causing people to see more of that content. So last month, we gave the reply predictor a 15x boost if it's a friend's post -- and it reduced ragebait by [an] order of magnitude." Read more of this story at Slashdot.

  • Army Unit Offers 4-Day Pass to Play GTA VI As Reenlistment Incentive
    by BeauHD on 19/08/2026 at 4:12 pm

    A U.S. Army battalion at Fort Stewart is offering soldiers a four-day pass timed to the release of Grand Theft Auto VI if they reenlist for at least two years. The program is limited to one unit for now, but it fits the Army's broader effort to appeal to gamers as a recruiting and retention pool. CBS News reports: Twenty soldiers at Fort Stewart in Georgia in the Army's 9th Brigade Engineering Battalion, part of the 3rd Infantry Division, have already chosen this incentive as part of their reenlistment, an Army spokesperson told CBS News on Wednesday. "The idea was to have a unique incentives program that connects to what Soldiers are interested in," Lt. Col. Angel Tomko, a spokesperson for the 3rd Infantry Division, said in a statement. "The command team, in conjunction with the career counselor, wanted to get soldiers excited to reenlist." [...] The Army memo, which has circulated online, says any soldier who signs a reenlistment contract between Aug. 1, 2026 and Nov. 14 will be authorized for a special four-day pass designated to coincide with "the highly anticipated release of the video game Grand Theft Auto VI (GTA 6)." About 130 soldiers are currently eligible for the incentive, Tomko said. Eligible soldiers must reenlist for a minimum of two years and up to six years. Read more of this story at Slashdot.
