Optimizing Neural Networks on a Brain-Inspired Computer

Many computational properties are maximized when the dynamics of a network are at a "critical point", a state where systems can quickly change their overall characteristics in fundamental ways, transitioning e.g. between order and chaos or stability and instability. Therefore, the critical state is widely assumed to be optimal for any computation in recurrent neural networks, which are used in many AI applications.

World's Smallest Imaging Device has Heart Disease in Focus

A team of researchers led by the University of Adelaide and University of Stuttgart has used 3D micro-printing to develop the world's smallest, flexible scope for looking inside blood vessels. The camera-like imaging device can be inserted into blood vessels to provide high quality 3D images to help scientists better understand the causes of heart attack and heart disease progression, and could lead to improved treatment and prevention.

Clinical-Grade Wearables Offer Continuous Monitoring for COVID-19

Although it might be tempting to rely on your fitness tracker to catch early signs of COVID-19, Northwestern University researchers caution that consumer wearables are not sophisticated enough to monitor the complicated illness.

Social Media and Radiology - The Good, the Bad, and the Ugly

Bradley Spieler, MD, Vice Chairman of Radiology Research at LSU Health New Orleans School of Medicine, is the lead author of a Radiology Research Alliance paper examining the usefulness of social media in Radiology. It is published online as an Article in Press online in Academic Radiology.

The New Tattoo: Drawing Electronics on Skin

One day, people could monitor their own health conditions by simply picking up a pencil and drawing a bioelectronic device on their skin. In a new study, University of Missouri engineers demonstrated that the simple combination of pencils and paper could be used to create devices that might be used to monitor personal health.

Chatbots can Ease Medical Providers' Burden, Offer Guidance to Those with COVID-19 Symptoms

COVID-19 has placed tremendous pressure on health care systems, not only for critical care but also from an anxious public looking for answers. Research from the Indiana University Kelley School of Business found that chatbots - software applications that conduct online chats via text or text-to-speech - working for reputable organizations can ease the burden on medical providers and offer trusted guidance to those with symptoms.

Towards an AI Diagnosis Like the Doctor's

Artificial intelligence (AI) is an important innovation in diagnostics, because it can quickly learn to recognize abnormalities that a doctor would also label as a disease. But the way that these systems work is often opaque, and doctors do have a better "overall picture" when they make the diagnosis.
