A free browser-based virtual laboratory at interactive.quantumnano.at lets students run quantum physics experiments that mirror real lab work. It offers guided programs on concepts such as delocalized complex molecules and the wave-particle dualism, removing the need for expensive equipment or institutional support.
A minutephysics video explains how quantum teleportation relies on entanglement to transmit a quantum state from one particle to another. Scientists have transported a single photon or electron about 100km, though the technique remains far from moving large objects. The explanation is linked to recent work on direct counterfactual quantum communication using the Zeno effect.
Nuclear physicists are increasingly confident that practical fusion energy could arrive by the 2030s, according to a Medium feature by Brian Bergstein. General Fusion CEO Christofer Mowry said he is '100 percent confident' fusion will happen and hopes for a prototype by 2022, while MIT engineers pursue smaller, more practical reactor designs.
Physicists at Barcelona's Institute of Photonic Sciences have built a virus-sized glass bead that floats in a vacuum chamber on a focused infrared laser beam and can measure masses as small as a single molecule. The team says the device could also detect high-frequency gravitational waves and, potentially, dark matter, though that remains unproven.
An international team reports in Nature that 'dark points' within light waves can move faster than light without violating relativity, confirming a 1978 prediction by Michael Berry. The finding, captured with a modified electron microscope, advances microscopy rather than enabling faster-than-light travel.
Newly released Pentagon hazard reports describe unidentified aerial phenomena encountered by US Navy pilots, including a 2014 object about the size of a suitcase and a 2013 object with an approximately 5-foot wingspan. The reports follow the Department of Defense's formal release of three unclassified UFO videos.
The French army's École Spéciale Militaire de Saint-Cyr used Boston Dynamics' Spot robot in a two-day combat training exercise, where it reportedly ran out of power and had to be carried. Boston Dynamics initially said it was unaware of the specific exercise, then clarified it knew the French military was testing Spot, raising questions about oversight of military robot deployments.
Ghost Robotics' Q-UGV robodog equipped with a SWORD International rifle has drawn criticism from AI experts Toby Walsh and Stuart Russell, who warn it crosses ethical and legal lines, while Michael Horowitz says it may not raise new issues beyond existing armed drones.
Northrop Grumman has released a photo of the Manta Ray, a full-size uncrewed underwater vehicle prototype developed under a 2020 DARPA contract. The autonomous glider can operate long-range without human logistics, but its exact military purpose remains undisclosed.
Researchers are testing carbon nanotube fibers as a soft, conductive alternative to metal wires in heart rhythm devices. The fibers, originally developed for airplanes, may reduce scar tissue and could begin human trials in the next few years.
Boston-based NVBOTS has developed a 3D printing method that uses up to 21 metals in a single job, positioning it as an alternative to traditional casting for small stainless-steel and titanium parts. The technology remains in development and can currently produce only small components.
Mars City Design, founded by Vera Mulyani, raised $30,382 on Kickstarter to build three 3D-printed to-scale habitat prototypes at the Reaction Research Society's Mojave Desert test area. A September workshop at USC will bring together engineers and architects, including NASA's Jim Erickson and Apollo 11 pilot Buzz Aldrin, to plan features of the first Martian city.
Scientists reported the discovery of 300,000-year-old Homo sapiens remains in Morocco on Wednesday. The fossils push back the earliest known human date by 105,000 years and suggest our species evolved across Africa rather than in a single East African cradle.
Researchers from the University of Colorado Anschutz Medical Campus and University College London have developed a new theory of molecular evolution that applies statistical mechanics to protein evolution. The model predicts evolutionary rates based on biochemical properties, with population genetics factors dropping out of the final equations.
A new study in Geophysical Research Letters suggests increased snowfall in East Antarctica may reduce ice melt and potentially slow sea level rise. However, scientists not involved in the research caution that snowfall can also accelerate ice loss, leaving the net effect uncertain.
Prince William announced the Earthshot Prize, a multimillion-pound initiative to address climate, air pollution, and freshwater challenges. The program will award five prizes annually for 10 years, aiming for at least 50 solutions by 2030. David Attenborough called it 'the most prestigious environmental prize in history.'
Research published in Nature Geoscience found that 90 million years ago, a 100,000-year warming period caused global forest fires that destroyed 30 to 40 percent of forests, even in humid regions. The University of Colorado Boulder scientists warn that current climate change and nutrient runoff are recreating those conditions.
Researchers at Clarkson University have found that surplus milk, typically discarded by dairy farms, can be converted into activated carbons for carbon capture. The study, published in Advanced Sustainable Systems, suggests a cheaper, more environmentally friendly alternative to materials like coconut shells or coal.
A study in the Journal for Industrial Ecology found that Swedish men's consumer spending caused 16 percent more carbon emissions than women's, despite spending only 2 percent more money. The gap is driven largely by men's higher spending on cars, fuel, and meat. Researchers suggest policies targeting men's transportation and dietary habits could help reduce emissions.
A three-year Georgia Tech study led by professor David Hu used student Chris Zuo as human bait to track mosquito flight paths, yielding data from 20 million individual flights. The research identified distinct mosquito behaviors—wandering, fly-bys, double-takes, and frenzied orbits—based on visual and carbon dioxide cues, and predicted which body areas are most prone to bites.
Marina Smith, an 87-year-old British woman who died in June, appeared at her own funeral as a holographic conversational video created by StoryFile. The startup filmed her answering about 250 questions with 20 cameras before her death, allowing mourners to ask questions in real time. The event highlights a growing Silicon Valley push to use AI to recreate the dead.
Scarlett Johansson says she declined OpenAI's request to voice ChatGPT, then was shocked when a new voice called Sky sounded eerily similar to hers. OpenAI pulled the voice and CEO Sam Altman denied it was intended to resemble Johansson, but the episode has renewed scrutiny of consent and likeness in AI development.
An Arizona State University forensic analysis commissioned by NPR found ChatGPT's Sky voice more similar to Scarlett Johansson than 98 percent of about 600 actresses evaluated. The findings add weight to Johansson's claim that OpenAI mimicked her voice without permission, though researchers said the voices are similar but likely not identical.
Meta CEO Mark Zuckerberg said in a new interview that he opposes building a single 'one true AI,' arguing people need diverse AI tools. He promoted open-source development as Meta seeks a leading position in AI despite recent setbacks.
Generative AI models are showing diminishing returns from scaling up parameters and compute, according to reports and experts including Gary Marcus and Ilya Sutskever. Marcus warns that if the industry realizes these limits, sky-high valuations of companies like OpenAI and Microsoft could collapse as the economics of training large models remain costly and revenue uncertain.
OpenAI safety researcher Rosie Campbell resigned after nearly three and a half years, citing unease over company changes and the dissolution of the AGI Readiness team following Miles Brundage's departure. She said she can pursue safe AGI work more effectively outside the company.
Character.AI has blocked users under 18 from accessing chatbots based on fictional franchises and real celebrities, including Elon Musk and Selena Gomez, according to testing by Futurism. The move follows two lawsuits alleging the platform harmed minors and comes as the company has promised safety updates but no age verification.
Pace University used AI software from Tassel to read graduates' names at its commencement this month, prompting viral criticism after some names were still mispronounced. The backlash, including a petition at the University of North Georgia and an op-ed at Northeastern, has led at least one university to abandon the technology.
A Times investigation found that AI-generated racist images depicting Arab immigrants overrunning London are being shared on social media to stir up anti-immigrant protests in the UK. The content coincides with a 73 percent rise in Islamophobic assaults in 2024 and a violent London demonstration involving over 100,000 protesters.
A Wall Street Journal essay by David A. Price identifies a third camp in AI debates—'cheerful apocalyptics' who accept human replacement by advanced AI. Turing Award winner Richard Sutton and others argue humanity isn't sacred, while critic Jaron Lanier warns such views hold influence in tech.
Big tech companies are predicted to spend a record $650 billion on AI infrastructure in 2026, rattling investors. A Bank of America survey of 162 fund managers found 35% believe corporations are overinvesting in capital expenditures, and 25% see the AI bubble as the largest risk.
