Switching water sources improved hygiene of Pompeii’s public baths

Switching water sources improved hygiene of Pompeii’s public baths

The eruption of Mount Vesuvius in 79 CE released thermal energy roughly equivalent to 100,000 times the atomic bombs dropped on Hiroshima and Nagasaki at the end of World War II, spewing molten rock, pumice, and hot ash over Pompeii. Pompeii's public baths, aqueduct, and water towers were among the preserved structures frozen in time. A new paper published in the Proceedings of the National Academy of Sciences analyzed calcium carbonate deposits from those structures to learn more about the city's water supply and how it changed over time.

Pompeii was founded in the sixth century BCE. Prior research revealed that, early on, the city relied on rainwater stored in cisterns and wells for its water supply. The public baths used weight-lifting machinery to lift water up well shafts that were as deep as 40 meters. As the city developed, so did the complexity of its water supply system, most notably with the construction of an aqueduct between 27 BCE and 14 CE.

The authors of this latest paper were interested in the calcium carbonate deposits left by water in well shafts as well as the baths and aqueduct. The different layers have "different chemical and isotope composition, calcite crystal size, and shape," which in turn could reveal information about seasonal changes in temperature, as well as changes over time in the chemical composition of the water. Analyzing those properties would enable them to "reconstruct the history of such systems—particularly public baths—revealing aspects of their maintenance and the adaptations made during their period of use," the authors wrote.

UK probes X over Grok CSAM scandal; Elon Musk cries censorship

UK probes X over Grok CSAM scandal; Elon Musk cries censorship

fivenewscrypto    janvier 13, 2026   

Elon Musk's X is currently under investigation in the United Kingdom after failing to stop the platform's chatbot, Grok, from generating thousands of sexualized images of women and children.

On Monday, UK media regulator Ofcom confirmed that X may have violated the UK's Online Safety Act, which requires platforms to block illegal content. The proliferation of "undressed images of people" by X users may amount to intimate image abuse, pornography, and child sexual abuse material (CSAM), the regulator said. And X may also have neglected its duty to stop kids from seeing porn.

"Reports of Grok being used to create and share illegal non-consensual intimate images and child sexual abuse material on X have been deeply concerning," an Ofcom spokesperson said. "Platforms must protect people in the UK from content that’s illegal in the UK, and we won’t hesitate to investigate where we suspect companies are failing in their duties, especially where there’s a risk of harm to children."

NASA topples towers used to test Saturn rockets, space shuttle

NASA topples towers used to test Saturn rockets, space shuttle

fivenewscrypto    janvier 13, 2026   

Two historic NASA test facilities used in the development of the Saturn V and space shuttle launch vehicles have been demolished after towering over the Marshall Space Flight Center in Alabama since the start of the Space Age.

The Propulsion and Structural Test Facility, which was erected in 1957—the same year the first artificial satellite entered Earth orbit—and the Dynamic Test Facility, which has stood since 1964, were brought down by a coordinated series of implosions on Saturday, January 10. Located in Marshall's East Test Area on the US Army's Redstone Arsenal in Huntsville, the two structures were no longer in use and, according to NASA, had a backlog of $25 million in needed repairs.

"This work reflects smart stewardship of taxpayer resources," Jared Isaacman, NASA administrator, said in a statement. "Clearing outdated infrastructure allows NASA to safely modernize, streamline operations and fully leverage the infrastructure investments signed into law by President Trump to keep Marshall positioned at the forefront of aerospace innovation."

The most fascinating monitors at CES 2026

The most fascinating monitors at CES 2026

CES 2026 took place in Las Vegas last week, and as usual, we're looking at the most interesting monitors from the show. Not every display is a monitor in the strictest sense, but they all provide a display for computers and have a unique twist that make them worth exploring.

It was a pretty safe bet that Dell would announce new UltraSharp monitors at CES. The displays are a solid recommendation for reliable USB-C monitors, including for Mac users and people needing something polished for professional or creative work. In recent years, UltraSharp monitors have also boasted more modern features, including integrated web cameras and IPS Black tech.

This year, the strategy was clear: Bigger is better.

That time Will Smith helped discover new species of anaconda

That time Will Smith helped discover new species of anaconda

fivenewscrypto    janvier 12, 2026   

In 2024, scientists announced the discovery of a new species of giant anaconda in South America. A National Geographic camera crew was on hand for the 2022 expedition that documented the new species—and so was actor Will Smith, since they were filming for NatGeo's new documentary series, Pole to Pole with Will Smith. Now we can all share in Smith's Amazon experience, courtesy of the three-minute clip above.

Along with venom expert Bryan Fry, we follow Smith's journey by boat with a team of indigenous Waorani guides, scouring the river banks for anacondas. And they find one: a female green anaconda about 16 to 17 feet long, "pure muscle." The Waorani secure the giant snake—anacondas aren't venomous but they do bite—so that Fry (with Smith's understandably reluctant help) can collect a scale sample for further analysis. Fry says that this will enable him to determine the accumulation of pollutants in the water.

That and other collected samples also enabled scientists to conduct the genetic analysis that resulted in the declaration of a new species: the northern green anaconda (Eunectes akayama, which roughly translates to "the great snake"). It is genetically distinct from the southern green anaconda (Eunectes murinus); the two species likely diverged some 10 million years ago. The northern green anaconda's turf includes Venezuela, Colombia, Suriname, French Guyana, and the northern part of Brazil.

The oceans just keep getting hotter

The oceans just keep getting hotter

fivenewscrypto    janvier 12, 2026   

Since 2018, a group of researchers from around the world has crunched the numbers on how much heat the world’s oceans are absorbing each year. In 2025, their measurements broke records once again, making this the eighth year in a row that the world’s oceans have absorbed more heat than in the years before.

The study, which was published Friday in the journal Advances in Atmospheric Science, found that the world’s oceans absorbed an additional 23 zettajoules’ worth of heat in 2025, the most in any year since modern measurements began in the 1960s. That’s significantly higher than the 16 additional zettajoules they absorbed in 2024. The research comes from a team of more than 50 scientists across the United States, Europe, and China.

A joule is a common way to measure energy. A single joule is a relatively small unit of measurement—it’s about enough to power a tiny lightbulb for a second, or slightly heat a gram of water. But a zettajoule is one sextillion joules; numerically, the 23 zettajoules the oceans absorbed this year can be written out as 23,000,000,000,000,000,000,000.

Google: Don’t make “bite-sized” content for LLMs if you care about search rank

Google: Don’t make “bite-sized” content for LLMs if you care about search rank

fivenewscrypto    janvier 12, 2026   

Search engine optimization, or SEO, is a big business. While some SEO practices are useful, much of the day-to-day SEO wisdom you see online amounts to superstition. An increasingly popular approach geared toward LLMs called "content chunking" may fall into that category. In the latest installment of Google's Search Off the Record podcast, John Mueller and Danny Sullivan say that breaking content down into bite-sized chunks for LLMs like Gemini is a bad idea.

You've probably seen websites engaging in content chunking and scratched your head, and for good reason—this content isn't made for you. The idea is that if you split information into smaller paragraphs and sections, it is more likely to be ingested and cited by generative AI bots like Gemini. So you end up with short paragraphs, sometimes with just one or two sentences, and lots of subheds formatted like questions one might ask a chatbot.

According to Sullivan, this is a misconception, and Google doesn't use such signals to improve ranking. "One of the things I keep seeing over and over in some of the advice and guidance and people are trying to figure out what do we do with the LLMs or whatever, is that turn your content into bite-sized chunks, because LLMs like things that are really bite size, right?" said Sullivan. "So... we don't want you to do that."
