Seeing electron movement at fastest speed ever could help unlock next-level quantum computing
New technique could enable processing speeds a million to a billion times faster than today's computers and spur progress in many-body physics Study: Attosecond clocking of correlations between Bloch electrons (DOI: 10.1038/s41586'022 -05190-2) (available when embargo lifts) The key to maximizing traditional or quantum computing speeds lies in our ability to understand how electrons behave in solids, and a collaboration between the University of Michigan and the University of Regensburg captured electron movement in attoseconds-the fastest speed yet.

With artificial intelligence to new materials
With artificial intelligence to new materials
In a pilot project, machine learning is helping to develop materials for hydrogen storage, for example. Artificial intelligence is opening up new possibilities in the development of new materials. Particularly in the search for materials for special applications such as high-entropy alloys, which contain several components in roughly equal proportions, machine learning could support research.

MIT system ’sees’ the inner structure of the body during physical rehab
A system for monitoring motion and muscle engagement could aid the elderly and athletes during unsupervised physical rehabilitation for injuries or impaired mobility. A growing number of people are living with conditions that could benefit from physical rehabilitation - but there aren't enough physical therapists (PTs) to go around.

AI-driven ’thermal attack’ system reveals passwords in seconds
Computer security experts have developed a system capable of guessing computer and smartphone users' passwords in seconds by analysing the traces of heat their fingertips leave on keyboards and screens. Researchers from the University of Glasgow developed the system, called ThermoSecure, to demonstrate how falling prices of thermal imaging cameras and rising access to machine learning are creating new risks for 'thermal attacks.' Thermal attacks can occur after users type their passcode on a computer keyboard, smartphone screen or ATM keypad before leaving the device unguarded.

UBC students help NASA find landslides by training computers to read Reddit
UBC students help NASA find landslides by training computers to read Reddit
Science, Health & Technology Alex Walls UBC graduate students trained computers to "read" news articles about landslides on Reddit to bolster a NASA database, which could improve predictions of when and where these natural disasters will occur. For their Master of Data Science in Computational Linguistics capstone project, Badr Jaidi and his team, the Social Landslides group, trained computers to automatically extract useful information from relevant news articles about landslides that were posted to Reddit.

Risks of sharing health care data are low
Greater availability of de-identified patient health data would enable better treatments and diagnostics, the researchers say. In recent years, scientists have made great strides in their ability to develop artificial intelligence algorithms that can analyze patient data and come up with new ways to diagnose disease or predict which treatments work best for different patients.

Climate simulation more realistic with Artificial Intelligence
Climate simulation more realistic with Artificial Intelligence
Machine learning improves climate models Accurately modeling extreme precipitation events remains a major challenge for climate models. These models predict how the earth's climate may change over the course of decades and even centuries. To improve them especially with regard to extreme events, researchers now use machine learning methods otherwise applied to image generation.

Learning on the edge
Learning on the edge
A new technique enables AI models to continually learn from new data on intelligent edge devices like smartphones and sensors, reducing energy costs and privacy risks. Microcontrollers, miniature computers that can run simple commands, are the basis for billions of connected devices, from internet-of-things (IoT) devices to sensors in automobiles.

Scientific discovery for stockpile stewardship
Scientific discovery for stockpile stewardship
Scientific discovery during the Stockpile Stewardship Program maintains confidence in the nuclear deterrent without testing, brings other benefits The last nuclear test, code-named Divider, took place 30 years ago, on September 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration.

The Future of Classroom Experimentation
With access to some of the best digital tools and learning systems ever seen, it's a wonder that there is currently no easy way for teachers to conduct experiments to see what is working best in their classrooms. Carnegie Mellon University and its partners were recently awarded a nearly $3 million National Science Foundation grant to fund a new framework for adaptive experimentation in classrooms and digital learning spaces like CMU's (OLI) and the Carnegie Learning K-12 platform.

An AI-system that explains its own outcomes can improve heart examination for underserved communities
Explainable AI (XAI) is an exciting new field in computer science. PhD-candidate Ana Lucic developed some new algorithms to make the black box of machine learning more transparant. One of them could help healthcare in underserved communities. Lucic will defend her PhD-thesis on Friday 23 September at the UvA.

In-home wireless device tracks disease progression in Parkinson's patients
In-home wireless device tracks disease progression in Parkinson’s patients
By continuously monitoring a patient's gait speed, the system can assess the condition's severity between visits to the doctor's office. Parkinson's disease is the fastest-growing neurological disease, now affecting more than 10 million people worldwide, yet clinicians still face huge challenges in tracking its severity and progression.

New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
New Software Platform Advances Understanding of the Surface Finish of Manufactured Components
Scientists develop platform that combines measurements of surface topography in a digital twin Scientists from the University of Freiburg, Germany, and the University of Pittsburgh have developed a software platform that facilitates and standardizes the analysis of surfaces. The platform enables users to create a digital twin of a surface and thus to help predict, for example, how quickly it wears out, how well it conducts heat, or how well it adheres to other materials.

Quantum algorithms help computers understand language
PhD candidate uses tools from quantum mechanics to help computers interpret ambiguous language. Words or sentences can often have multiple meanings. This is a concept that is hard to grasp for regular computers. PhD candidate Adriana Duarte Correia used quantum algorithms to make computers understand that a sentence like 'Look at the dog with one eye' can mean two different things at the same time.

A smartphone’s camera and flash could help people measure blood oxygen levels at home
First, pause and take a deep breath. When we breathe in, our lungs fill with oxygen, which is distributed to our red blood cells for transportation throughout our bodies. Our bodies need a lot of oxygen to function, and healthy people have at least 95% oxygen saturation all the time. Conditions like asthma or COVID-19 make it harder for bodies to absorb oxygen from the lungs.

Bird’s’eye view improves safety of autonomous driving
The expectations for autonomous driving are clear: "Cars have to travel safely not only at low speeds, but also in fast-moving traffic," says Jörg Schrepfer, the Head of Driving Advanced Research Germany at Valeo. For example, when objects fall off a truck, the "egocentric" perspective of a car will often be unable to detect the hazardous debris in time.
