Artificial brains may need sleep too
Artificial brains may need sleep too
States that resemble sleep-like cycles in simulated neural networks quell the instability that comes with uninterrupted self-learning in artificial analogs of brains LOS ALAMOS, N.M., June 8, 2020-No one can say whether androids will dream of electric sheep, but they will almost certainly need periods of rest that offer benefits similar to those that sleep provides to living brains, according to new research from Los Alamos National Laboratory.

Engineers put tens of thousands of artificial brain synapses on a single chip
Engineers put tens of thousands of artificial brain synapses on a single chip
The design could advance the development of small, portable AI devices. MIT engineers have designed a "brain-on-a-chip," smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors - silicon-based components that mimic the information-transmitting synapses in the human brain.

USB software security tool catches 26 bugs across operating systems
USB software security tool catches 26 bugs across operating systems
EPFL researchers have developed a new tool called USBFuzz, which they have already used to detect 26 vulnerabilities in the USB driver stacks of widely used operating systems including Linux, Windows, and macOS. USB driver stacks are components that help computers communicate with external devices via the Universal Serial Bus (USB) connection.

Search-and-rescue algorithm identifies hidden
Search-and-rescue algorithm identifies hidden "traps" in ocean waters
Method may help quickly identify regions where objects - and missing people - may have converged. The ocean is a messy and turbulent space, where winds and weather kick up waves in all directions. When an object or person goes missing at sea, the complex, constantly changing conditions of the ocean can confound and delay critical search-and-rescue operations.

Complex data workflows contribute to reproducibility crisis
Markedly different conclusions about brain scans reached by 70 independent teams highlight the challenges to data analysis in the modern era of mammoth datasets and highly flexible processing workflows. Scientific research has changed dramatically in the centuries since Galileo, Newton and Darwin. Whereas scientists once often toiled in isolation with homemade experiments and treatises, today collaboration is the norm.

New technique separates industrial noise from natural seismic signals
New technique separates industrial noise from natural seismic signals
A transformative, cloud-computing approach to analyzing data helps researchers better understand seismic activity For the first time, we were able to identify this noise from some large machines as a distinct signal and pull it from the dataset, allowing us to separate natural signals from anthropogenic ones.

AI successfully used to identify different types of brain injuries
AI successfully used to identify different types of brain injuries
Researchers at Imperial College London and Cambridge have developed an AI algorithm that can detect and identify different types of brain injuries. The researchers found that their machine learning algorithm was able to detect, segment, quantify and differentiate between types of brain lesions using images of CT scans.

Safe landings in rough seas
Safe landings in rough seas
Landing a helicopter on the deck of a ship in poor visibility is a big challenge even for the most experienced of pilots. Researchers at the Technical University of Munich (TUM) have developed an assistance system that displays key information in the visor of the pilot's helmet-mounted display. This permits precise landing approaches - even in adverse weather conditions.

3 Questions: The rapidly unfolding future of smart fabrics
3 Questions: The rapidly unfolding future of smart fabrics
Soon, your clothes may be able to monitor your vital signs, analyze the results, and warn you of health risks. In an opinion piece published in the journal Matter, members of the Fibers@MIT research group recently laid out a detailed vision for how the rapidly growing field of  advanced fibers and fabrics could transform many aspects of our lives.

New AI Enables Teachers to Rapidly Develop Intelligent Tutoring Systems
"Teaching computers to teach” is key, say Carnegie Mellon researchers Intelligent tutoring systems have been shown to be effective in helping to teach certain subjects, such as algebra or grammar, but creating these computerized systems is difficult and laborious. Now, researchers at Carnegie Mellon University have shown they can rapidly build them by, in effect, teaching the computer to teach.

A 'veil of darkness' reduces racial bias in traffic stops
A ’veil of darkness’ reduces racial bias in traffic stops
After analyzing 95 million traffic stop records, filed by officers with 21 state patrol agencies and 35 municipal police forces from 2011 to 2018, researchers concluded that "police stops and search decisions suffer from persistent racial bias." The largest-ever study of alleged racial profiling during traffic stops has found that blacks, who are pulled over more frequently than whites by day, are much less likely to be stopped after sunset, when "a veil of darkness" masks their race.

Catching nuclear smugglers: Fast algorithm could enable cost-effective detectors at borders
Catching nuclear smugglers: Fast algorithm could enable cost-effective detectors at borders
A new algorithm could enable faster, less expensive detection of weapons-grade nuclear materials at borders, quickly differentiating between benign and illicit radiation signatures in the same cargo. The development is a collaboration among researchers at the University of Michigan, University of Illinois, Los Alamos National Laboratory, Heriot-Watt University (Edinburgh, Scotland) and University of Edinburgh.

Researchers devise new model to track COVID-19’s spread
Yale University researchers and colleagues in Hong Kong and China have developed an approach for rapidly tracking population flows that could help policymakers worldwide more effectively assess risk of disease spread and allocate limited resources as they combat the COVID-19 pandemic. The approach, described in a study published early online on April 29 , differs from existing epidemiological models by exploiting real-time data about population flows, such as phone use data and other "big data" sources that can accurately quantify the movement of people.
