A new analysis of 89 major geological events over the past 260 million years found evidence that mass extinctions, volcanic eruptions, ocean crises, and other upheavals may cluster around a roughly 27.5-million-year cycle. The cause remains unknown, with possibilities ranging from mantle activity and orbital changes to speculative galactic influences. Slashdot reader alternative_right shares a report from ScienceAlert: One possibility lies deep within Earth itself. The planet's mantle is constantly circulating through convection, albeit at an almost unimaginably slow pace. Periodic changes in mantle convection, or the initiation of mantle plumes, could influence volcanism, plate tectonics, mountain building, and other large-scale geological processes. Because these systems are closely interconnected, disturbances originating deep within Earth could eventually ripple through the planet's surface, oceans, climate, and biosphere. Another hypothesis focuses on interactions between Earth's surface and interior. Long-term orbital variations influence climate and sea level, periodically redistributing enormous amounts of water, ice, and sediment across the planet. [New York University geologist Michael Rampino] discusses the possibility that these changing surface loads subtly modify stresses within Earth's crust and upper mantle, potentially influencing tectonic and volcanic activity over geological timescales. Rampino also considers possible influences beyond Earth, an idea he has been weighing up since the 1980s. As the Solar System orbits the center of the Milky Way, it oscillates above and below the galaxy's mid-plane, with the timing of these passages aligning with that of Earth's major upheavals. These crossings, other researchers have suggested, could also gravitationally perturb comets in the distant Oort Cloud, increasing the likelihood of large asteroid impacts. Another, even more speculative, hypothesis suggests that if dark matter is concentrated near the galactic plane, a fraction of it could occasionally be captured by Earth. Over millions of years, this process could generate small amounts of internal heat, potentially influencing geological activity. At present, however, there is no direct evidence supporting either mechanism, so they remain very controversial. Large asteroid impacts are discussed separately in the paper. Although they were not included in the statistical analysis of the 89 geological events, the timing of several of Earth's largest known impact craters appears broadly consistent with the proposed 27.5-million-year rhythm, as Rampino has discussed in earlier papers. Rampino suggests this correspondence may warrant further investigation, but stops short of claiming a causal relationship.

An anonymous reader quotes a report from Ars Technica: One missing underscore in a Skyrim-themed username put an innocent Nova Scotia man in prison for 18 months. A 2018 child-luring investigation, which began in Madison, Wisconsin, and eventually extended to Halifax, Canada, was based on a false premise. Police were looking for a man using the Kik messaging service under the name "fus__ro_dah" (two underscores after "fus"), but they accidentally requested records for the username "fus_ro_dah" (one underscore after "fus"). This one-character difference led them not to the perpetrator but to a Canadian man named Brandon Klayme. (Ars readers may recognize "fus ro dah" as the Unrelenting Force "dragon shout" from The Elder Scrolls V: Skyrim.) Despite finding no evidence of the crime on his digital devices, Canadian police arrested Klayme in 2020 on child sex abuse charges. He was convicted after a trial in 2023 and sentenced in 2024 to 18 months in prison. He served the full term. Even after release, Klayme continued to fight his conviction. In the process of preparing his appeal, the username mistake that led to all these years of disruption was finally discovered. On Thursday, the Nova Scotia Court of Appeal overturned Klayme's conviction, writing: "Mr. Klayme is factually innocent of the offences. He should never have been charged, let alone convicted." [...] As the court puts it, "Although the information about the usernames was available at the time of the trial, there is no evidence confirming or explaining how it went unnoticed."

YouTube Premium will include Peacock Premium at no extra charge beginning in early 2027. "The deal brings a slew of premium content to the [$15.99 per month] YouTube Premium subscription, including live sports like the NFL, NBA and MLB and entertainment like Law & Order, Saturday Night Live and Love Island," reports The Hollywood Reporter. "It also has the potential to dramatically scale Peacock, which remains smaller than many of its streaming competitors." From the report: Peacock has 48 million subscribers, while YouTube Premium and YouTube Music have a combined 125 million subscribers, though they don't break out how many each of those offerings have. The agreement, which expands on the deal the company inked with YouTube parent company Google last year, will also extend the entertainment company's programming deal with YouTube TV, while bringing some of YouTube's offerings to Comcast Xfinity and Xumo platforms. There's also a notable sports and production element to the deal, with NBC Sports agreeing to stream some live sporting events on its YouTube channels, and with NBC agreeing to serve as the production partner for select live events on YouTube. YouTube will also bundle some of the company's International streaming offerings like Universal+ and Hayu in select markets.
