China Tests Low-Cost Catalyst to Turn Plastic Waste Into Jet Fuel
Researchers in China have demonstrated a chemical process that converts polyolefin plastic waste into aviation-grade fuel using a cobalt-nickel catalyst, but the method remains at the laboratory stage and faces significant engineering hurdles
Nuclear-Powered Container Ship Design Receives Initial Safety Approval
A 15,000 TEU container ship concept using small modular reactors has received Approval in Principle from the American Bureau of Shipping, marking a step toward nuclear propulsion in commercial shipping but raising new safety and engineering questions
UCLA Team Integrates Terahertz Generation and Detection on One Chip
A UCLA research group has demonstrated a semiconductor chip that combines terahertz signal generation and detection, using quantum-well photodiodes and standard fabrication methods, potentially enabling scalable terahertz systems for communications and sensing
AI System Tested in Remotely Piloted F-16 Without Core Software Rewrite
A modified F-16 fighter jet was flown under AI control in a supervised test by DARPA and the US Air Force, using the VENOM Autonomy Kit to enable remote operation without altering the aircraft's core flight software
Cypriot Gold Ornaments Reveal Ancient Mediterranean Connections
Archaeologists have analyzed a cache of 3,400-year-old gold ornaments from chamber tombs at Hala Sultan Tekke, Cyprus, uncovering evidence of local craftsmanship influenced by Egyptian, Mycenaean, Minoan, and Near Eastern traditions
Atmosphere detected on rocky exoplanet in habitable zone
Astronomers have identified helium escaping from LHS 1140 b, a super-Earth orbiting in its star's habitable zone, using infrared spectroscopy. The finding offers the strongest evidence yet that a rocky exoplanet can retain an atmosphere for billions of years
Webb Telescope Maps Gas Feeding a Supermassive Black Hole
Astronomers using the James Webb Space Telescope have mapped gas flows around a supermassive black hole, revealing a self-regulating cycle that may explain rapid black hole growth in the early universe
Hayabusa2's Risky Asteroid Flyby Yields Unprecedented Close-Up Data
Japan's Hayabusa2 spacecraft has captured detailed images and thermal data of the near-Earth asteroid Torifune after a high-speed flyby, following intense debate over the mission's safety and scientific value
Webb Telescope Uses Gravitational Lensing to Reveal Ancient Galaxies
The James Webb Space Telescope has captured a detailed image of the galaxy cluster MACS J0553.4-3342, using gravitational lensing to magnify galaxies from the universe's first billion years
Bronze Age Sword Recovered from Protected Wreck off Devon Coast
A 3,000-year-old Bronze Age sword has been recovered by volunteer divers from the Salcombe Cannon and Moor Sand sites off south Devon, offering new evidence for prehistoric maritime activity and trade in the region
Roman Female Farm Managers Oversaw Wine and Oil Production
A new analysis of Roman-era texts and archaeological evidence reveals that women known as vilicae managed large-scale wine and olive oil production, challenging the long-held view that their roles were limited to domestic tasks
Hybrid Photon-Atom Quantum Blueprint Targets Error Correction Limits
Quantum Source Alpha Labs has released a detailed hardware proposal for a hybrid photon-atom quantum computing architecture, aiming to address scaling and error correction challenges that limit current quantum processors
Digital Survey Reveals Medieval Bridge Remains at Chester Castle
Archaeologists using advanced digital scanning have identified the remains of a 13th-century bridge beneath Chester Castle in England, challenging previous assumptions about the site's medieval architecture and preservation
NASA Develops VTE Risk Algorithm for Astronauts on ISS Missions
NASA's medical office has established a new risk assessment algorithm for venous thromboembolism (VTE) in astronauts, following updated case reviews and in-flight blood flow data from International Space Station missions
Large Hadron Collider Detects Particle Wake Predicted After Big Bang
Researchers at CERN's Large Hadron Collider have observed a long-sought wake effect in quark-gluon plasma, offering new insight into the behavior of matter under extreme conditions similar to those just after the Big Bang
Asteroid Apophis to Make Exceptionally Close Approach in 2029
Researchers have mapped the 2029 flyby of asteroid Apophis, predicting that up to 90% of Earth's population could see the object with the naked eye as it passes closer than many satellites, offering a rare opportunity for direct observation
Dark Energy Camera Reveals Star Formation in Corona Australis Cloud
The Dark Energy Camera has imaged the Corona Australis Molecular Cloud, capturing intricate details of a nearby star-forming region and highlighting the interplay of gas, dust, and young stars in one of the closest stellar nurseries to Earth
Reverse Sprinkler Experiments Reveal Angular Momentum Mechanism
Researchers at New York University have built custom rotary sprinklers to investigate the reverse sprinkler problem, measuring how angular momentum and device geometry affect rotation when water is drawn in rather than expelled
Extreme Solar Storms May Exceed Previous Impact Estimates
A new analysis of solar wind data suggests that the most powerful solar storms could cause greater geomagnetic disturbances on Earth than previously calculated, with implications for satellites and power grids
Quantum entanglement measured in heavy-fermion strange metal
