Published Artificial intelligence: Aim policies at 'hardware' to ensure AI safety, say experts



Chips and datacentres -- the 'compute' power driving the AI revolution -- may be the most effective targets for risk-reducing AI policies as they have to be physically possessed, according to a new report.
Published Fundamental equation for superconducting quantum bits revised



Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are 2 to 7 times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe.
Published Widespread machine learning methods behind 'link prediction' are performing very poorly



New research establishes that the metric used to measure link prediction performance is missing crucial information, and link prediction tasks are performing significantly worse than popular literature indicates.
Published Why insects navigate more efficiently than robots



Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published Innovations in depth from focus/defocus pave the way to more capable computer vision systems



In an image, estimating the distance between objects and the camera by using the blur in the images as clue, also known as depth from focus/defocus, is essential in computer vision. However, model-based methods fail when texture-less surfaces are present, and learning-based methods require the same camera settings during training and testing. Now, researchers have come up with an innovative strategy for depth estimation that combines the best of both the worlds to solve these limitations, extending the applicability of depth from focus/defocus.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts



A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published Combining materials may support unique superconductivity for quantum computing



A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing.
Published Computer-engineered DNA to study cell identities



A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. It will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.
Published A sleeker facial recognition technology tested on Michelangelo's David



Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report on a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo's David just as well as an existing smartphone system.
Published A physical qubit with built-in error correction



Researchers have succeeded in generating a logical qubit from a single light pulse that has the inherent capacity to correct errors.
Published How to run a password update campaign efficiently and with minimal IT costs



Computer scientists found that email notifications to update passwords potentially yielded diminishing returns after three messages. They also found that a prompt to update passwords while users were trying to log in was effective for those who had ignored email reminders. Researchers also found that users whose jobs didn't require much computer use struggled the most with the update.
Published Promising heart drugs ID'd by cutting-edge combo of machine learning, human learning



Scientists have developed a new approach to machine learning -- a form of artificial intelligence -- to identify drugs that help minimize harmful scarring after a heart attack or other injuries.
Published Engineers develop hack to make automotive radar 'hallucinate'



Engineers have demonstrated a system they've dubbed 'MadRadar' for fooling automotive radar sensors into believing almost anything is possible. The technology can hide the approach of an existing car, create a phantom car where none exists or even trick the radar into thinking a real car has quickly deviated from its actual course. And it can achieve this feat in the blink of an eye without having any prior knowledge about the specific settings of the victim's radar, making it the most troublesome threat to radar security to date.
Published Scientists make breakthrough in quantum materials research



Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
Published Bringing together real-world sensors and VR to improve building maintenance



A new system that brings together real-world sensing and virtual reality would make it easier for building maintenance personnel to identify and fix issues in commercial buildings that are in operation.
Published AI-powered app can detect poison ivy



To find poison ivy before it finds you, scientists have published a new study in which they show how they used artificial intelligence to confirm that an app can identify poison ivy. The app is not yet commercially available, nor is there a timetable for it to be available.
Published Researchers craft new way to make high-temperature superconductors -- with a twist



An international team has developed a new method to make and manipulate a widely studied class of high-temperature superconductors. This technique should pave the way for the creation of unusual forms of superconductivity in previously unattainable materials.
Published Utilizing active microparticles for artificial intelligence



Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.
Published A long-lasting neural probe



An interdisciplinary team of researchers has developed a soft implantable device with dozens of sensors that can record single-neuron activity in the brain stably for months.
Published Chats with AI shift attitudes on climate change, Black Lives Matter



People who were more skeptical of human-caused climate change or the Black Lives Matter movement who took part in conversation with a popular AI chatbot were disappointed with the experience but left the conversation more supportive of the scientific consensus on climate change or BLM. This is according to researchers studying how these chatbots handle interactions from people with different cultural backgrounds.
