	An approach that allows robots to learn in changing environments from human feedback and exploration To best assist humans in real-world settings, robots should be able to continuously acquire useful new skills in dynamic and rapidly changing environments. Currently, however, most robots can only tackle tasks that they have been previously trained on and can only acquire new capabilities after further training.
	ChatGPT creates persuasive, phony medical report A common truism among statisticians is that "the data don't lie." However, recent findings by Italian researchers may make those who study data think twice before making such assumptions.
	Improved water electrolysis performance and stability bring commercialization of green hydrogen one step closer A technology has been developed by Professor Youngkook Kwon's team in the School of Chemical Engineering at UNIST, aiming to significantly improve the performance of an electrolyzer used for hydrogen generation. This advancement brings us a step closer to the commercialization of green hydrogen production technology.
	Using large language models to code new tasks for robots You've likely heard that "experience is the best teacher"—but what if learning in the real world is prohibitively expensive? This is the plight of roboticists training their machines on manipulation tasks. Real-world interaction data is costly, so their robots often learn from simulated versions of different activities.
	Researchers engineer a material that can perform different tasks depending on temperature Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.

	Tesla's futuristic Cybertruck finally arrives—here's why the company's success is riding on it In 2019, Tesla was in the happy position of being a high-volume, premium-priced leader in the global electric vehicle (EV) market. Deliveries of 367,500 cars represented 50% growth over 2018.
	Virtual reality training could reduce gender gap in some spatial tasks Finding out why men and women perform differently in some tasks is a matter of controversy with no scientific consensus. One of the areas under study is that of visuospatial abilities, where a number of studies have shown that men are better at certain tasks, such as mental rotation or egocentric spatial cognition, which involves locating elements in space by reference to one's own body rather than other objects.
	Researchers develop large language model for medical knowledge Researchers from EPFL have just released Meditron, the world's best performing open source large language model tailored to the medical field designed to help guide clinical decision-making.
	How AI 'sees' the world: What happened when we trained a deep learning model to identify poverty To most effectively deliver aid to alleviate poverty, you have to know where the people most in need are. In many countries, this is often done with household surveys. But these are usually infrequent and cover limited locations.
	Researchers develop greener building materials using sugar processing waste products If you want to make more sustainable and environmentally friendly concrete, you're going to need some sugar. Sort of.
	EU activists launch legal fight over Meta's 'pay for privacy' scheme An Austrian activist group filed a complaint against tech giant Meta on Tuesday arguing that the firm's scheme allowing Europeans to pay to opt out of data sharing was illegal.
	Virgin pilots first transatlantic flight with low-carbon fuel British airline Virgin Atlantic on Tuesday piloted the first long-haul flight powered entirely by Sustainable Aviation Fuel (SAF), an event environmental groups labeled "greenwashing".
	Algorithm appreciation overcomes algorithm aversion, advertising content study finds Advertising content generated by artificial intelligence (AI) is perceived as being of higher quality than content produced by human experts, according to a new research paper in Judgment and Decision Making.
	Detonation-based device for novel propulsion applications Combustors that drive propulsion systems are often volumetric in nature, typically in the form of cylinders, and convert chemical to thermal and mechanical energy through oxidation of fuels. This deflagrating combustion approach is now beginning to be challenged by detonation-based combustion that utilizes shock waves to accelerate the oxidation of fuel-air mixture.
	No significant link between Industry 4.0 and energy consumption or energy intensity To what extent does the digitalization of industrial and manufacturing processes (Industry 4.0) improve energy efficiency and thus reduce energy intensity? A team from the Research Institute for Sustainability (RIFS) analyzed developments across 10 industrial manufacturing sectors in China between 2006 and 2019. Their findings show that contrary to the claims of many policymakers and industry associations, digitalization may not automatically lead to anticipated energy savings in manufacturing and industry in China.
	Innovative wireless light switch could cut house wiring costs in half A University of Alberta engineering researcher has developed a wireless light switch that could reduce the cost of wiring a house by as much as 50%.
	Unsafe and illegal e-scooter riding linked to lack of rule knowledge E-scooter riders are less likely to ride dangerously or illegally if they know the rules and regulations, according to a new research report by Nottingham Trent University (NTU) that calls for better access to training programs to reduce collisions.
	Organic solar cells show promise for cheap energy production, researcher says A newly published doctoral thesis at Karlstad University shows that organic solar cells are a promising technology, due to its flexibility and vast potential applications.
	Co-learning to improve autonomous driving Self-driving cars are both fascinating and fear-inducing, as they must accurately assess and navigate the rapidly changing environment. Computer vision, which uses computation to extract information from imagery, is an important aspect of autonomous driving, with tasks ranging from low level, such as determining how far away a given location is from the vehicle, to higher level, such as determining if there is a pedestrian in the road.
	Workers suffer when AI gets it wrong, argues professor Amazon thought it had found an efficient way to find the best workers. Recruitment is time consuming and expensive, so why not outsource it to artificial intelligence (AI)?
