Published Clinicians could be fooled by biased AI, despite explanations
(via sciencedaily.com) Original source A new study finds that clinicians were fooled by biased AI models, even with provided explanations for how the model generated its diagnosis.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Interactive screen use reduces sleep time in kids
(via sciencedaily.com) Original source While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watching television -- especially for teens.
Published The solar forest
(via sciencedaily.com) Original source What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.
Published Saving endangered species: New AI method counts manatee clusters in real time
(via sciencedaily.com) Original source Accurately counting manatee aggregations within a region is crucial yet challenging. Harnessing the power of AI, researchers are using a deep learning-based crowd counting approach to automatically count the number of manatees in a designated region, using images captured from CCTV cameras, which are readily available, as input. The pioneering study not only addresses the technical challenges of counting in complex outdoor environments but also offers potential ways to aid endangered species.
Published Free electric vehicle charging at work? It's possible with optimum solar
(via sciencedaily.com) Original source The global surge in electric vehicle sales has prompted an Australian university to explore how it could offer free or nominal EV charging facilities to staff and students by optimizing its solar PV system and minimizing workplace electricity costs.
Published 'Energy droughts' in wind and solar can last nearly a week
(via sciencedaily.com) Original source Understanding the risk of compound energy droughts -- times when the sun doesn't shine and the wind doesn't blow -- will help grid planners understand where energy storage is needed most.
Published Made-to-order diagnostic tests may be on the horizon
(via sciencedaily.com) Original source Researchers have made a breakthrough in diagnostic technology, inventing a 'lab on a chip' that can be 3D-printed in just 30 minutes. The chip has the potential to make on-the-spot testing widely accessible.
Published Researchers safely integrate fragile 2D materials into devices
(via sciencedaily.com) Original source A new technique integrates 2D materials into devices and systems in a single step, while keeping surfaces and interfaces free from defects. This method could enable devices like those in computer chips to achieve better performance than those made with conventional fabrication techniques.
Published Polyethylene waste could be a thing of the past
(via sciencedaily.com) Original source Experts have developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis. PE is the most widely used plastic in the world including for daily food packaging, shopping bags and reagent bottles, and the researchers say that while recycling of PE is still in early development, it could be an untapped resource for re-use.
Published Immersive VR goggles for mice unlock new potential for brain science
(via sciencedaily.com) Original source New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published World's first logical quantum processor
(via sciencedaily.com) Original source A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.
Published ChatGPT often won't defend its answers -- even when it is right
(via sciencedaily.com) Original source ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong.
Published Magnetization by laser pulse
(via sciencedaily.com) Original source To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team has discovered some time ago that a certain iron alloy can be magnetized with ultrashort laser pulses.
Published Diamonds and rust help unveil 'impossible' quasi-particles
(via sciencedaily.com) Original source Researchers have discovered magnetic monopoles -- isolated magnetic charges -- in a material closely related to rust, a result that could be used to power greener and faster computing technologies.
Published Harvesting more solar energy with supercrystals
(via sciencedaily.com) Original source Hydrogen is a building block for the energy transition. To obtain it with the help of solar energy, researchers have developed new high-performance nanostructures. The material holds a world record for green hydrogen production with sunlight.
Published 2D material reshapes 3D electronics for AI hardware
(via sciencedaily.com) Original source Researchers demonstrated monolithic 3D integration of layered 2D material into novel processing hardware for artificial intelligence computing. The new approach provides a material-level solution for fully integrating many functions into a single, small electronic chip -- and paves the way for advanced AI computing.
Published Smart microgrids can restore power more efficiently and reliably in an outage
(via sciencedaily.com) Original source A new AI model that optimizes the use of renewables and other energy sources outperforms traditional power restoration techniques for islanded microgrids, a new paper shows.
Published Straining memory leads to new computing possibilities
(via sciencedaily.com) Original source A team of researchers developed a new form of computing memory that is fast, dense, and low-power by strategically straining materials that are as thin as a single layer of atoms.
