Predicting what someone is about to do next based on their body language comes naturally to humans but not so for computers. When we meet another person, they might greet us with a hello, handshake, or even a fist bump. We may not know which gesture will be used, but we can read the situation and respond appropriately. In a new study, Columbia Engineering researchers unveil a … [Read more...] about AI learns to predict human behavior from videos

‘Edge of chaos’ opens pathway to artificial intelligence discoveries: Nanowire network trained to solve simple problem mimicking neural pathways
Scientists at the University of Sydney and Japan's National Institute for Material Science (NIMS) have discovered that an artificial network of nanowires can be tuned to respond in a brain-like way when electrically stimulated. The international team, led by Joel Hochstetter with Professor Zdenka Kuncic and Professor Tomonobu Nakayama, found that by keeping the network of … [Read more...] about ‘Edge of chaos’ opens pathway to artificial intelligence discoveries: Nanowire network trained to solve simple problem mimicking neural pathways
Stretching changes the electronic properties of graphene
The electronic properties of graphene can be specifically modified by stretching the material evenly, say researchers at the University of Basel. These results open the door to the development of new types of electronic components. Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice. The material is very flexible and has excellent electronic … [Read more...] about Stretching changes the electronic properties of graphene
RAMBO speeds searches on huge DNA databases: Method cuts indexing times from weeks to hours, search times from hours to minutes
Rice University computer scientists are sending RAMBO to rescue genomic researchers who sometimes wait days or weeks for search results from enormous DNA databases. DNA sequencing is so popular, genomic datasets are doubling in size every two years, and the tools to search the data haven't kept pace. Researchers who compare DNA across genomes or study the evolution of organisms … [Read more...] about RAMBO speeds searches on huge DNA databases: Method cuts indexing times from weeks to hours, search times from hours to minutes
AI used to predict unknown links between viruses and mammals
A new University of Liverpool study could help scientists mitigate the future spread of zoonotic and livestock diseases caused by existing viruses. Researchers have used a form or artificial intelligence (AI) called machine-learning to predict more than 20,000 unknown associations between known viruses and susceptible mammalian species. The findings, which are published in … [Read more...] about AI used to predict unknown links between viruses and mammals
Nanotech OLED electrode liberates 20% more light, could slash display power consumption: A five-nanometer-thick layer of silver and copper outperforms conventional indium tin oxide without adding cost
A new electrode that could free up 20% more light from organic light-emitting diodes has been developed at the University of Michigan. It could help extend the battery life of smartphones and laptops, or make next-gen televisions and displays much more energy efficient. The approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to … [Read more...] about Nanotech OLED electrode liberates 20% more light, could slash display power consumption: A five-nanometer-thick layer of silver and copper outperforms conventional indium tin oxide without adding cost
Backscatter breakthrough runs near-zero-power IoT communicators at 5G speeds everywhere: Low-cost, low-power devices work over mmWave and use a single transistor to transfer high-volume data anywhere
The promise of 5G Internet of Things (IoT) networks requires more scalable and robust communication systems -- ones that deliver drastically higher data rates and lower power consumption per device. Backscatter radios -- passive sensors that reflect rather than radiate energy -- are known for their low-cost, low-complexity, and battery-free operation, making them a potential … [Read more...] about Backscatter breakthrough runs near-zero-power IoT communicators at 5G speeds everywhere: Low-cost, low-power devices work over mmWave and use a single transistor to transfer high-volume data anywhere
Unbroken: New soft electronics don’t break, even when punctured
A team of Virginia Tech researchers from the Department of Mechanical Engineering and the Macromolecules Innovation Institute has created a new type of soft electronics, paving the way for devices that are self-healing, reconfigurable, and recyclable. These skin-like circuits are soft and stretchy, sustain numerous damage events under load without losing electrical … [Read more...] about Unbroken: New soft electronics don’t break, even when punctured
Fast IR imaging-based AI identifies tumor type in lung cancer
The examined tissue does not need to be marked for this. The analysis only takes around half an hour. "This is a major step that shows that infrared imaging can be a promising methodology in future diagnostic testing and treatment prediction," says Professor Klaus Gerwert, director of PRODI. The study is published in the American Journal of Pathology on 1 July 2021. Treatment … [Read more...] about Fast IR imaging-based AI identifies tumor type in lung cancer
Deep machine learning completes information about the bioactivity of one million molecules
A tool developed by the Structural Bioinformatics and Network Biology lab at IRB Barcelona predicts the biological activity of chemical compounds, key information to evaluate their therapeutic potential. Using artificial neural networks, scientists have inferred experimental data for a million compounds and have developed a package of programs to make estimates for any type of … [Read more...] about Deep machine learning completes information about the bioactivity of one million molecules
