Published AI 'brain' created from core materials for OLED TVs
(via sciencedaily.com) 
A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Paper written using ChatGPT demonstrates opportunities and challenges of AI in academia
(via sciencedaily.com) 
In an innovative new study, researchers used a series of prompts and questions to encourage ChatGPT to produce the type of content commonly seen in academic publications. Researchers say in their paper's discussion section -- which was written without the software's influence -- that it demonstrates the new levels of sophistication which AI now offers and also the opportunities and challenges it poses for the academic community.
Published Uracil found in Ryugu samples
(via sciencedaily.com) 
Samples from the asteroid Ryugu collected by the Hayabusa2 mission contain nitrogenous organic compounds, including the nucleobase uracil, which is a part of RNA.
Published 'Inkable' nanomaterial promises big benefits for bendable electronics
(via sciencedaily.com) 
An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published 3D-printed revolving devices can sense how they are moving
(via sciencedaily.com) 
Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.
Published Notre-Dame de Paris Cathedral was historical first in using iron reinforcements in the 12th century
(via sciencedaily.com) 
The Notre-Dame de Paris is the first known cathedral of Gothic-style architecture to be initially constructed with extensive use of iron to bind stones together. The 2019 fire that significantly damaged the cathedral enabled analyses leading to this discovery.
Published Resilient bug-sized robots keep flying even after wing damage
(via sciencedaily.com) 
Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.
Published Neolithic ceramics reveal dairy processing from milk of multiple species
(via sciencedaily.com) 
A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) 
The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
Published Virtual reality games can be used as a tool in personnel assessment
(via sciencedaily.com) 
Fast gamers are more intelligent: Intelligence can be predicted through virtual reality games.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) 
Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Researchers unveil smart contact lens, capable of implementing AR-based navigation
(via sciencedaily.com) 
A research team has introduced core technology for smart contact lenses that can implement AR-based navigation through a 3D printing process.
Published Viable superconducting material created, say researchers
(via sciencedaily.com) 
Researchers report the creation of a superconducting material at both a temperature and pressure low enough for practical applications. In a new paper, the researchers describe a nitrogen-doped lutetium hydride that exhibits superconductivity at 69 degrees Fahrenheit and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.
Published New breakthrough enables perfectly secure digital communications
(via sciencedaily.com) 
Researchers have achieved a breakthrough to enable 'perfectly secure' hidden communications for the first time. The method uses new advances in information theory methods to conceal one piece of content inside another in a way that cannot be detected. This may have strong implications for information security, besides further applications in data compression and storage.
Published Can artificial intelligence help find life on Mars or icy worlds?
(via sciencedaily.com) 
Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published Edible electronics: How a seaweed second skin could transform health and fitness sensor tech
(via sciencedaily.com) 
Scientists have developed biodegradable algae-based hydrogels for strain sensing devices -- such as those used in health monitors worn by runners and hospital patients to track heart rate -- using natural elements like rock salt, water and seaweed, combined with graphene. As well as being more environmentally friendly than polymer-based hydrogels, commonly used in health sensor technology, the graphene algae sensors perform strongly in terms of sensitivity.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond
(via sciencedaily.com) 
Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published Quantum chemistry: Molecules caught tunneling
(via sciencedaily.com) 
Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in theory. The scientists provide an important reference for this fundamental effect in chemistry. It is the slowest reaction with charged particles ever observed.
