U-M senior’s COVID-19 data model reaches CDC
For Sabrina Corsetti, the pandemic presents an interesting problem-a data problem, that is. Her efforts to model the pandemic's spread using a machine learning algorithm has now been included in those being aggregated for the CDC's weekly projections. Corsetti, a senior majoring in physics and mathematics, had her previous research halted when the University of Michigan suspended in-person classes and labs back in March.

Researchers Train Autonomous Drones Using Cross-Modal Simulated Data
To fly autonomously, drones need to understand what they perceive in the environment and make decisions based on that information. A novel method developed by Carnegie Mellon University researchers allows drones to learn perception and action separately. The two-stage approach overcomes the "simulation-to-reality gap," and creates a way to safely deploy drones trained entirely on simulated data into real-world course navigation.

Contact tracing apps unlikely to contain COVID-19 spread
Contract tracing apps used to reduce the spread of COVID-19 are unlikely to be effective without proper uptake and support from concurrent control measures, finds a new study by UCL researchers. The systematic review*, published in Lancet Digital Health , shows that evidence around the effectiveness of automated contact tracing systems is currently very limited, and large-scale manual contact tracing alongside other public health control measures - such as physical distancing and closure of indoor spaces such as pubs - is likely to be required in conjunction with automated approaches.

AI automatic tuning delivers step forward in Quantum computing | University of Oxford
Researchers at Oxford University, in collaboration with DeepMind, University of Basel and Lancaster University, have created a machine learning algorithm that interfaces with a quantum device and 'tunes' it faster than human experts, without any human input. They are dubbing it 'Minecraft explorer for quantum devices'.

Sounds of Action: Using Ears, Not Just Eyes, Improves Robot Perception
Carnegie Mellon builds dataset capturing interaction of sound, action, vision People rarely use just one sense to understand the world, but robots usually only rely on vision and, increasingly, touch. Carnegie Mellon University researchers find that robot perception could improve markedly by adding another sense: hearing.

New microscopes to unravel the mysteries of brain organization
New microscopes to unravel the mysteries of brain organization
Researchers around the world share their stunning images and insights: The open source mesoSPIM Initiative The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today . The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever before.

Deep learning and metamaterials make the invisible visible
Deep learning and metamaterials make the invisible visible
By combining purpose-built materials and neural networks, researchers at EPFL have shown that sound can be used in high-resolution imagery. Imaging allows us to depict an object through far-field analysis of the lightand sound-waves that it transmits or radiates. The shorter the wave, the higher the image's resolution.

Whiteness of AI erases people of colour from our ’imagined futures’, researchers argue
The overwhelming 'Whiteness' of artificial intelligence - from stock images and cinematic robots to the dialects of virtual assistants - removes people of colour from the way humanity thinks about its technology-enhanced future. If the developer demographic does not diversify, AI stands to exacerbate racial inequality Kanta Dihal This is according to experts at the University of Cambridge, who suggest that current portrayals and stereotypes about AI risk creating a "racially homogenous" workforce of aspiring technologists, building machines with bias baked into their algorithms.

New high-capacity embedded memories use half as much silicon
New high-capacity embedded memories use half as much silicon
Researchers at EPFL and Bar Ilan University have developed a new type of embedded memory that takes up half as much space as traditional memory - and uses less energy - to store a given amount of data. The technology is being marketed through a new spin-off called RAAAM. Embedded memories play a crucial role in running our digital devices, from computers and smartphones all the way to the internet of things and entire telecom networks.

New imaging system creates pictures by measuring time
A radical new method of imaging which harnesses artificial intelligence to turn time into visions of 3D space could help cars, mobile devices and health monitors develop 360-degree awareness. Photos and videos are usually produced by capturing photons - the building blocks of light - with digital sensors.

Trust in data privacy increases during pandemic
COVID-19 has seen Australians become more trusting of organisations and governments when it comes to their personal data and privacy, according to new research. The Australian National University (ANU) study examined more than 3,200 Australians' attitudes toward data privacy and security before and during the coronavirus pandemic, including the use of the COVIDSafe app.

"Giant atoms" enable quantum processing and communication in one
Researchers devise an on-off system that allows high-fidelity operations and interconnection between processors. MIT researchers have introduced a quantum computing architecture thatcan perform low-error quantum computations while also rapidly sharing quantum information between processors. The work represents a key advance toward a complete quantum computing platform.

More effective sharing of research data
National research data infrastructure: TUM involved in three consortia Genome sequencing produces immense quantities of data. The aim of the German Human Genome-Phenome Archive (GHGA) is to make these data available to science without violating the personality rights of patients. The GHGA will focus initially on data collections pertaining to cancer and rare genetic disorders.

Machine learning reveals recipe for building artificial proteins
Proteins are essential to cells, carrying out complex tasks and catalyzing chemical reactions. Scientists and engineers have long sought to harness this power by designing artificial proteins that can perform new tasks, like treat disease, capture carbon or harvest energy, but many of the processes designed to create such proteins are slow and complex, with a high failure rate.

Technology that makes it feel like you're touching virtual objects
Adding to the richness of virtual reality, EPFL researchers have created soft actuators that can simulate the feeling of touching a virtual object with your fingers. In the virtual world, the objects you pick up do not exist: you can see that cup or pen, but it does not feel like you're touching them.

Video Game Teaches Productive Civil Discourse and Overcoming Tribalism
Carnegie Mellon researcher develops instructional tool to combat information bubbles A Carnegie Mellon University researcher is proposing that students can learn to make their civil discourse more productive through an video game powered by artificial intelligence. The educational system targeted toward high schoolers adapts to students' specific values and can be used to measure - and in some cases reduce - the impact of bias.
