DNA Nets Capture Sars-CoV-2 for Detection and Inhibition

Medgadget: A team at the University of Illinois at Urbana-Champaign has developed a DNA net system that can ensnare Sars-CoV-2 and bind to the notorious spike protein. The nets contain aptamers that bind the spike protein and emit an intense…

A bionic pancreas could solve one of the biggest challenges of diabetes

Technology Review: In a recent trial, a bionic pancreas that automatically delivers insulin proved more effective than pumps or injections at lowering blood glucose levels in people with type 1…

Wearable sensor tracks tumor growth

Futurity: A small, autonomous device with a stretchable and flexible sensor that adheres to the skin can measure the changing size of tumors below the surface, a new study with mice shows. The non-invasive, battery-operated device is sensitive to one-hundredth of a millimeter (10 micrometers) and can beam results…

E-Skin Sensors Go Chipless and Batteryless

IEEE Spectrum: Wearable sensors now often help keep track of vital signs, but these devices usually rely on bulky microchips and batteries. Now scientists have invented a new microscopically thin “electronic skin” that can wirelessly transmit data about the body’s heart…
