Submission + - How Long Poop Stays in Your Body Could Impact Your Health, Study Finds (sciencealert.com)

Submitted by alternative_right
alternative_right writes: According to a 2023 review that brought together data from dozens of studies, distinct differences can be seen between the gut microbiomes of 'speeders' and 'slowpokes'.

Since the human gut microbiome is intrinsically linked to health, this could have implications that have gone unnoticed before now.

In particular, slow transit times and constipation have been linked with metabolic and inflammatory disorders, as well as neurological disorders such as Parkinson's disease.

Submission + - The internet works thanks to a shared infrastructure that nobody owns (elpais.com) 1

Submitted by alternative_right
alternative_right writes: In the 21st century, every government should understand that ensuring software sovereignty and security is part of its job, not only for themselves but also for businesses, society, and researchers. In the 21st century, software is the invisible infrastructure of our everyday life, like roads and bridges. Everything runs on software, and a significant portion of this is made possible by open source, which is maintained by people selflessly. If this open source breaks down, it’s as if a road or bridge collapses: everything else becomes much more complicated and dangerous.

Submission + - 'Slop Evader' Lets You Surf the Web Like It's 2022 (404media.co)

Submitted by alternative_right
alternative_right writes: AI slop feels inescapable — whether you’re watching TV, reading the news, or trying to find a new apartment.

That is, unless you’re using Slop Evader, a new browser tool that filters your web searches to only include results from before November 30, 2022 — the day that ChatGPT was released to the public.

The tool is available for Firefox and Chrome, and has one simple function: Showing you the web as it was before the deluge of AI-generated garbage. It uses Google search functions to index popular websites and filter results based on publication date, a scorched earth approach that virtually guarantees your searches will be slop-free.

Submission + - Ion-based cooling technique could make computer chips more powerful (phys.org)

Submitted by alternative_right
alternative_right writes: [R]esearchers at The University of Osaka have developed a strategy to enhance cooling by driving the flow of ions through nanoscale channels. This ionothermoelectric strategy is analogous to the Peltier technique, in which passing an electric current through a material results in heating or cooling. This compelling invention is published in ACS Nano.

"We fabricated a nanosized pore in a semiconductor membrane and surrounded the nanopore with a 'gate,' in the form of a nanowire. Applying a voltage to the gate induced the flow of ions through the nanopore," explains lead author, Makusu Tsutsui. "Varying the voltage modulated the surface charge of the nanopore."

A negative applied voltage resulted in a negatively charged nanopore that was only permeable to positively charged ions, or cations. Consequently, each ion drags a certain quantity of heat along with its charge. The team created a concentration gradient in saltwater around the nanopore to drive cation transport in one direction, effectively pumping heat out of the nanopore. Reversing the applied voltage made the nanopore surface positive and permeable only to negative ions, or anions, therefore switching the system from cooling to heating.

Submission + - X Update Shows Foreign Origin for Many Political Accounts (apnews.com)

Submitted by skam240
skam240 writes: Elon Musk’s X unveiled a feature Saturday that lets users see where an account is based. Online sleuths and experts quickly found that many popular accounts posting in support of the MAGA movement to thousands or hundreds of thousands of followers, are based outside the United States — raising concerns about foreign influence on U.S. politics.

Researchers at NewsGuard, a firm that tracks online misinformation, identified several popular accounts — purportedly run by Americans interested in politics – that instead were based in Eastern Europe, Asia or Africa.

The accounts were leading disseminators of some misleading and polarizing claims about U.S. politics, including ones that said Democrats bribed the moderators of a 2024 presidential debate.

Submission + - Crime Rings Enlist Hackers to Hijack Trucks (archive.is)

schwit1 writes: By breaking into carriers’ online systems, cyber-powered criminals are making off with truckloads of electronics, beverages and other goods

In the most recent tactics identified by cybersecurity firm Proofpoint, hackers posed as freight middlemen, posting fake loads to the boards. They slipped links with malicious software into email exchanges with bidders such as trucking companies. By clicking on the links, trucking companies unwittingly downloaded remote-access software that lets the hackers take control of their online systems.

Once inside, the hackers used the truckers’ accounts to bid on real shipments, such as electronics and energy drinks, said Selena Larson, a threat researcher at Proofpoint. “They know the business,” she said. “It’s a very convincing full-scale identity takeover.”

Submission + - Top MAGA Influencers Accidentally Unmasked as Foreign Trolls 4

Submitted by Nicholas Grayhame
Nicholas Grayhame writes: The Daily Beast reports: Elon Musk’s social media site X has rolled out a new feature in an effort to increase transparency—and unwittingly revealed that many of the site’s top MAGA influencers are actually foreign actors. The new “About This Account” feature, which became available to X users on Friday, allows others to see where an account is based, when they joined the platform, how often they have changed their username, and how they downloaded the X app. Upon rollout, rival factions began to inspect just where their online adversaries were really based on the combative social platform—with dozens of major MAGA and right-wing influencer accounts revealed to be based overseas....

Dozens of major accounts masquerading as “America First” or “MAGA” proponents have been identified as originating in places such as Russia, India, and Nigeria. In one example, the account MAGANationX—with nearly 400,000 followers and a bio reading “Patriot Voice for We The People”—is actually based in Eastern Europe. An Ivanka Trump fan account, IvankaNews, has 1 million followers and frequently posts about the dangers of Islam, the threat of illegal immigration and support for Trump. That account is based in Nigeria. ...

Donald Trump and several close associates were investigated for conspiracy or coordination with Russia during the 2016 election. Two of Trump’s campaign members were indicted. Certain content creators are paid for tweets that drive engagement on the site formerly known as Twitter, which gives them a financial incentive to cash in on the divisive nature of U.S. politics. For those in countries like Nigeria or Bangladesh, the American dollars paid by X for their work can make a big difference to their lives. X payouts are calculated on the basis of engagement from verified premium accounts with content on X.

Submission + - U.S. employee well-being hit new low in 2024, survey reveals (phys.org)

Submitted by alternative_right
alternative_right writes: The latest research confirms a decline in general employee well-being since 2020. In 2024, employees reported the lowest well-being scores on record, as opposed to 2020, when employees reported the highest well-being scores.

"In some cases, the lower scores represent a reduction in employee flexibility for either flexible hours or remote work," the latest research states. "In other cases, these scores could be related to challenges associated with greater economic shifts related to inflation or productivity needs."

"What we're seeing is a growing gap between how leaders and their teams experience the workplace," said Smith. "Managers may feel a return to normalcy, but that doesn't mean their employees do. Leaders must be cautious not to assume their own well-being reflects the broader workforce at their organization. The data shows a potential disconnect, and that's a signal for action."

Submission + - Moss spores survive 9 months outside International Space Station (phys.org)

Submitted by alternative_right
alternative_right writes: To find out, Fujita's team subjected Physcomitrium patens, a well-studied moss commonly known as spreading earthmoss, to a simulated a space environment, including high levels of UV radiation, extreme high and low temperatures, and vacuum conditions.

They tested three different structures from the moss—protenemata, or juvenile moss; brood cells, or specialized stem cells that emerge under stress conditions; and sporophytes, or encapsulated spores—to find out which had the best chance of surviving in space.

The researchers found that UV radiation was the toughest element to survive, and the sporophytes were by far the most resilient of the three moss parts. None of the juvenile moss survived high UV levels or extreme temperatures. The brood cells had a higher rate of survival, but the encased spores exhibited ~1,000x more tolerance to UV radiation. The spores were also able to survive and germinate after being exposed to 196C for over a week, as well as after living in 55C heat for a month.

That was my experience before ChatGPT 5. With ChatGPT 5, here comes the qualifier: if you use it within its training data range, it's quite good. Within its training data means, doing what other people have done before and is likely to be found on stackoverflow. For example, setting up training a neural network with torch. If you go outside their comfort zone, I agree with you.

Danger lives when these tools are used in an area where the user even lacks the expertise to factcheck the answer. The responses sound very confident.
