VR study: our visual world of color is incorrect
A study finds that people are aware of surprisingly limited color in their peripheral vision; much of our sense of a colorful visual world is likely constructed by our brain.
Using machine learning to estimate COVID-19’s seasonal cycle
Scientists are launching a project to apply machine learning methods to assess the role of climate variables in disease transmission
AI could help stem tide of school violence
Researchers developed an AI system that analyzes linguistic patterns to predict a youth’s risk for committing acts of school violence.
Brain-computer interfaces: AI reduces need for recalibration
Machine learning will drastically improve brain-computer interfaces and their ability to remain stabilized during use, greatly reducing or potentially eliminating the need to recalibrate these devices.
AI enables fast-track review of COVID-19 research proposals
An AI tool to help funders identify specialists to peer-review proposals for emergency COVID-19 research has been developed.
Scientists model heart attack on a chip
The chip is capable of precisely controlling oxygen and nutrient levels, and allowing observation of cell behavior in real time.
Robots uncover connections between mind and walking control
Researchers used robots to study how our brains adjust to changes in our walking strides, gaining insights that could be used to develop better physical rehabilitation programs.
AI outperform doctors: Experts express concerns
Many studies claiming that AI is as good as (or better than) human experts at interpreting medical images are of poor quality and are arguably exaggerated, warn researchers in The BMJ.
An ankle exoskeleton aids running
Researchers find that a motorized device that attaches around the ankle and foot can drastically reduce the energy cost of running.
Re-association of body parts using VR
Researchers report that a re-association of the right thumb with a virtual left arm can be induced by visuo-motor synchronization in a virtual environment.
Smart algorithm analyses whole brain vasculature
Scientists have developed a technique for visualising the structures of all the brain's blood vessels including any pathological changes.
4D printing may speed development of therapeutics
Researchers have created a 4D printer capable of constructing patterned surfaces that recreate the complexity of cell surfaces.
VR for early detection of MS balance problems
The UNC School of Medicine lab of Jason Franz, PhD, created virtual reality experiments to show how a potentially portable and inexpensive test could reduce falls and related injuries in people with multiple sclerosis.
Producing human tissue in space
The University of Zurich has sent adult human stem cells to the International Space Station to explore the production of human tissue in weightlessness.
AI challenge aims to improve mammography accuracy
AI techniques, used in combination with the evaluation of expert radiologists, improve the accuracy in detecting cancer using mammograms.
Robots on the march to walking like humans
A psychological theory could kickstart improvements in the way robots are able to walk, thanks to a study at the University of Manchester.
A precision chip recreates blood-brain barrier
Researchers at Georgia Tech have now developed a chip that accurately replicates its function using the human cells that form this important part of our anatomy.
A 'multitasking' AI tool quickly extracts cancer data
To better leverage cancer data for research, scientists are developing an artificial intelligence-based natural language processing tool to improve information extraction from textual pathology reports.
Human textiles to repair blood vessels
Researchers are developing “human textiles” from collagen in order to repair damaged blood vessels.

A game devised to make players better at spotting fake news and misinformation, has the intended effect in Sweden, Greece, Germany and Poland.
Researchers develops revolutionary reversible 4D printing
Researchers revolutionised 4D printing by making a 3D fabricated material change its shape and back again repeatedly without electrical components.
Children benefit from learning with social robots
Research has shown that explaining aloud what you are learning, whether to yourself or to someone else, leads to a better understanding of the subject.
Is virtual reality not suited to visual memory?
Researchers have found that virtual reality may interfere with visual memory.
Using tumor-on-a-chip to find cancer drugs
Researchers have developed a 'tumor-on-a-chip' that can better mimic the environment inside the body, paving the way for improved screening of potential cancer fighting drugs.
Mindfulness video game changes areas of the brain
Researchers designed a video game to improve mindfulness in middle schoolers and found that when young people played the game, they showed changes in areas of their brains that underlie attention.
Barking up the wrong tree with virtual reality
Researcher used virtual reality to trick 20 patients with with intermittent arterial claudication, and discovered that they could suddenly walk much further.
Virtual “moonwalk” for science
In order to orient ourselves in space, and to find our way around, we form mental maps of our surroundings. Scientists used VR to detect distortions in our spatial memory.
