Using a bit of machine learning magic, astrophysicists can now simulate vast, complex universes in a thousandth of the time it takes with conventional methods. The new approach will help usher in a new era in high-resolution cosmological simulations, its creators report in a study published online May 4 in Proceedings of the National Academy of Sciences. "At the moment, … [Read more...] about New application of AI just removed one of the biggest roadblocks in astrophysics

As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field. The enhanced measurement technologies enabled by quantum phenomena, and the possibility of scientific progress using new methods, are of particular interest to researchers around the world. Recently two researchers at Tampere University, … [Read more...] about Complex shapes of photons to boost future quantum technologies

Researchers have developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles. … [Read more...] about New synapse-like phototransistor

With the explosion in digital entertainment options over the past several decades and the more recent restrictions on outdoor and in-person social activities, parents may worry that excessive engagement with digital technology could have long-term effects on their children's mental health. A new study published in the journal Clinical Psychological Science, however, found … [Read more...] about Little to no increase in association between adolescents’ mental health problems and digital tech

Daegu Gyeongbuk Institute of Science and Technology (DGIST) scientists in Korea have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach they used was described in the journal IEEE Transactions on Information Forensics and Security and could reduce the computational complexity … [Read more...] about Algorithms improve how we protect our data: New algorithms are much better at estimating the security level of encrypted data

Artificial intelligence that enhances remote monitoring of water bodies -- highlighting quality shifts due to climate change or pollution -- has been developed by researchers at the University of Stirling. A new algorithm -- known as the 'meta-learning' method -- analyses data directly from satellite sensors, making it easier for coastal zone, environmental and industry … [Read more...] about Artificial intelligence to monitor water quality more effectively

A year into the COVID-19 pandemic, mass vaccinations have begun to raise the tantalizing prospect of herd immunity that eventually curtails or halts the spread of SARS-CoV-2. But what if herd immunity is never fully achieved -- or if the mutating virus gives rise to hyper-virulent variants that diminish the benefits of vaccination? Those questions underscore the need for … [Read more...] about Speeding new treatments: Team creates powerful computational tool to help researchers rapidly screen molecules for anti-COVID properties

Anyone with children knows that while controlling one child can be hard, controlling many at once can be nearly impossible. Getting swarms of robots to work collectively can be equally challenging, unless researchers carefully choreograph their interactions -- like planes in formation -- using increasingly sophisticated components and algorithms. But what can be reliably … [Read more...] about Simple robots, smart algorithms

Scientists from the Theory Department of the Fritz-Haber Institute in Berlin and Technical University of Munich use machine learning to discover suitable molecular materials. To deal with the myriad of possibilities for candidate molecules, the machine decides for itself which data it needs. How can I prepare myself for something I do not yet know? Scientists from the Fritz … [Read more...] about Toward new solar cells with active learning

Researchers from Osaka University, Japan and the University of Adelaide, Australia have worked together to produce the new multiplexer made from pure silicon for terahertz-range communications in the 300-GHz band. "In order to control the great spectral bandwidth of terahertz waves, a multiplexer, which is used to split and join signals, is critical for dividing the information … [Read more...] about Silicon chip will drive next generation communications
