Published 'Scientists' warning' on climate and technology
(via sciencedaily.com) Original source Throughout human history, technologies have been used to make peoples' lives richer and more comfortable, but they have also contributed to a global crisis threatening Earth's climate, ecosystems and even our own survival. Researchers have suggested that industrial civilization's best way forward may entail embracing further technological advancements but doing so with greater awareness of their potential drawbacks.
Published Artificial intelligence: Aim policies at 'hardware' to ensure AI safety, say experts
(via sciencedaily.com) Original source 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 Treating liver cancer with microrobots piloted by a magnetic field
(via sciencedaily.com) Original source Researchers have developed a novel approach to treat liver tumors using magnet-guided microrobots in an MRI device.
Published Fundamental equation for superconducting quantum bits revised
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published Why insects navigate more efficiently than robots
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 3D printed nanocellulose upscaled for green architectural applications
(via sciencedaily.com) Original source For the first time, a hydrogel material made of nanocellulose and algae has been tested as an alternative, greener architectural material. The study shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods.
Published GPT-3 transforms chemical research
(via sciencedaily.com) Original source Scientists demonstrate how GPT-3 can transform chemical analysis, making it faster and more user-friendly.
Published One person can supervise 'swarm' of 100 unmanned autonomous vehicles
(via sciencedaily.com) Original source Research involving has shown that a 'swarm' of more than 100 autonomous ground and aerial robots can be supervised by one person without subjecting the individual to an undue workload.
Published Computer-engineered DNA to study cell identities
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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'
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source Researchers describe the discovery of a new method that transforms everyday materials like glass into materials scientists can use to make quantum computers.
