Submission + - Companies Are Using Reddit to Manipulate ChatGPT and Google AI Search (404media.co)
alternative_right writes: The moderators of the biohacking subreddit say that peptide and hormone replacement therapy companies have been surreptitiously spamming Reddit in an attempt to get their posts scraped by AI chatbots. The strategy is an effort to systematically manipulate the answers provided by chatbots by manipulating the underlying source material that those chatbots will scrapeâ"in this case, a popular Reddit community.
Submission + - Physicists Just Achieved 'Perfect Randomness' For The First Time Ever (sciencealert.com) 1
alternative_right writes: To try to find a solution to this problem, the researchers turned to a quantum experiment known as the Bell test.
They created a pair of entangled quantum bits, or qubits, separated by 30 meters (98 feet) and cooled to temperatures close to absolute zero.
The ETH Zurich team instead demonstrated something called randomness amplification, deliberately starting with imperfect randomness â" taking randomness that may contain subtle flaws or biases and transforming it into randomness that can be certified as perfectly unpredictable.

Submission + - Something Made Earth's Molten Core Reverse Direction in 2010 (sciencealert.com)
alternative_right writes: In the molten ocean of iron churning in Earth's outer core, a section deep beneath the Pacific Ocean suddenly reversed direction and started moving eastward against the planet's usual westward flow.
This happened in 2010, according to satellite measurements of Earth's magnetic field, and scientists are still trying to figure out what caused it.

Submission + - Ordinary WiFi can now identify people with near perfect accuracy (sciencedaily.com) 1
alternative_right writes: Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively âoeseeâ and recognize individuals â" even if they are not carrying a device and even if their phone is turned off.
Submission + - Brain scans reveal a shocking difference between psychopaths and other people (sciencedaily.com)
alternative_right writes: Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum â" a brain region tied to reward, motivation, and decision-making â" that was about 10% larger on average than those without such traits. Using MRI scans and psychological assessments on 120 participants, researchers connected this enlarged brain region to thrill-seeking, impulsive behavior, and a stronger drive for stimulation.
Submission + - Scientists found the âoeholy grailâ gene that could one day help human (sciencedaily.com)
alternative_right writes: Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful âoeSP genesâ involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mice, marking a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics.
Submission + - How Laboratory Tests Fail in Application (phys.org)
alternative_right writes: Most studies showing that houseplants remove pollutants share a fundamental design feature: small, sealed chambers with artificially high concentrations of pollutants introduced as a single high dose. A plant is placed inside the chamber, concentrations of pollutants are measured over time and a removal rate is calculated. This design works well for comparing plants to each other. It works poorly for predicting what happens in your home.
The critical missing variable is what building scientists call the air exchange rate. This is how quickly outdoor air naturally replaces indoor air through gaps, walls and ventilation systems. In a real building, this constant dilution is already doing the heavy lifting on pollutant concentration. When a 2019 study modeled plant performance against real-world air exchange rates, it found you would need between ten and 1,000 plants per square meter to match what a building's passive ventilation already achieves.
So the scientifically defensible answer is: houseplants can remove some pollutants, but they are not an effective standalone air-cleaning solution for homes. That does not mean the earlier studies were "wrong." It means their results were often overextended into everyday settings where the physics of indoor air are very different.

Submission + - Your DNA may predict your future success more than your upbringing (sciencedaily.com)
alternative_right writes: A new twin study suggests your genes may play a bigger role in your future success than your upbringing. Researchers found that IQ, which is largely genetically influenced, strongly predicts education, career, and income. Even twins raised in the same household diverged based on genetic differences. The findings hint that life outcomes may be more hardwired than many people expect.

Submission + - Physicists just found a tiny flaw in time itself (sciencedaily.com) 1
alternative_right writes: Physicists are rethinking one of quantum mechanicsâ(TM) biggest puzzles: how fuzzy possibilities become definite reality. New research suggests that spontaneous âoecollapseâ processesâ"possibly linked to gravityâ"could subtly blur time itself.

alternative_right writes: A startup south of Austin is using robots to build homes out of clay pulled directly from the ground â" a new approach aimed at lowering costs and changing how houses are built.
Submission + - NASA engineers create ingenious way to save homes from wildfires using noise (nypost.com)
alternative_right writes: Former NASA engineers with California-based Sonic Fire Tech found that using sound waves can snuff out blazes and potentially be used to stop another Pacific Palisades inferno.
In order for flames to burn it needs three things, oxygen, fuel, and heat. The technology works by targeting oxygen molecules using low-frequency sound waves that vibrate them, stopping the fire from growing.
âoeSound waves vibrate the oxygen faster than the fuel can use it, and break the chemical reaction of the flame,â Remington Hotchkis, Chief Commercialization Officer at Sonic Fire Tech told The Post.

alternative_right writes: Researchers working with data from the Internet Archive have discovered that a third of websites created since 2022 are AI-generated. The team of researchersâ"which includes people from Stanford, the Imperial College London, and the Internet Archiveâ"published their findings online in a paper titled âoeThe Impact of AI-Generated Text on the Internet.â The research also found that all this AI-generated text is making the web more cheery and less verbose.
Submission + - Your phone's next speed boost may come from magnetic chips (phys.org)
alternative_right writes: A new technology has been proposed that could fundamentally solve the issue of smartphones overheating during high-spec gaming or extended video streaming. Researchers at KAIST have discovered the principle of processing signals using the minute vibrations of magnets (spin waves) instead of electrons. This method significantly reduces heat generation and power consumption while enabling instantaneous frequency switching within the several GHz range. This breakthrough is expected to pave the way for smart devices with less heat and longer battery life, as well as ultra-low-power, high-speed computing.
