UNL researchers discovered a new chromium/titanium carbide MXene with p-type properties, enhancing conductivity under light, which could create complex electronic structures when combined with n-type MXenes, expanding...
Advanced scientific techniques revealed the world's oldest ochre mine in Eswatini, dating back 40,000 years, showing how ancient humans mined, processed, and distributed ochre, offering insights into early cognition, social...
The next president must balance funding constraints, security concerns, and global competition while fostering international collaboration and attracting talent to maintain U.S. scientific leadership, especially in critical areas...
Deep Atomic, a Swiss startup, plans to build a 60-megawatt small modular reactor called MK60 for data centers. The reactor will provide both electricity and cooling, supporting energy-intensive AI applications and cloud services...
NASA astronaut Don Pettit, 69, has begun his third long-duration stay on the International Space Station. Known for his curiosity and science communication skills, Pettit performs both official NASA research and personal...
Apple has unveiled its 2024 iMac, featuring the new M4 chip for improved performance. The computer boasts up to 2.1 times faster speeds for demanding tasks compared to the M1 model. While maintaining its 24-inch 4.5K Retina...
Apple's new USB-C Magic Mouse maintains its criticized bottom-charging design, forcing users to flip it over and pause use during charging, despite the availability of alternative solutions and continued user feedback.
A fleet of 903 robotic floats measured global phytoplankton biomass at 314 teragrams, equivalent to 250 million elephants. Half of this biomass exists at depths undetectable by satellites, impacting climate change monitoring and...
The European Space Agency's Hera spacecraft has launched to investigate the site of NASA's DART mission impact on asteroid moonlet Dimorphos in 2022. Hera will survey the crater and gather data to improve planetary defense...
A recent proof demonstrates that Dijkstra's algorithm, developed in 1956, is the optimal method for finding the fastest route on any street grid under worst-case traffic conditions. The algorithm solves the single-source...
A new version of the Hall effect, discovered by Penn State researchers, operates without a magnetic field and exhibits non-reciprocal charge transport. This breakthrough could enable faster terahertz communication technologies,...
A new study reveals that daylight saving time changes significantly impact sleep duration, but only briefly. People sleep about an hour less when clocks spring forward, but gain only 30 minutes when they fall back, with different...
UNLV researchers created a solar-powered system using a hydrogel membrane, inspired by tree frogs and air plants, to extract drinking water from air in dry climates, producing a gallon daily from a 3x3 foot area in Las Vegas.
Saturn's moon Titan has a unique methane clathrate ice crust up to six miles thick, according to a new study by University of Hawaii researchers. This crust warms Titan's interior, causing rapid crater shallowing and potentially...
