The story behind COVID-19 vaccinesPHOTO: NATIONAL INSTITUTE OF ALLERGY AND INFECTIOUS DISEASESAmid the staggering amount of suffering and death during this historic pandemic of COVID-19, a remarkable success story stands out. The development of several highly efficacious vaccines against a previously unknown viral pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in less than 1 year from the identification of the virus is unprecedented in the history of vaccinology. A frequently asked question is how such an extraordinary accomplishment could have been realized in such a short time frame, when timelines for other vaccines are measured in years if not decades. In fact, concern about this truncated timeline has contributed in part to the hesitancy in accepting these vac...

Artificial nervous system senses light and learns to catch like humans By Chris Stokel-Walker An artist’s impression of neuronsKTSDESIGN/SCIENCE PHOTO LIBRARY A simple artificial nervous system is able to mimic the way humans respond to light and learn to perform basic tasks. The principle could be used to create more useful robots and prostheses. Humans, when confronted by external stimuli such as heat or light, can react rapidly and automatically – think about how your hand withdraws from a hot surface, or how your leg flicks up when tapped on the knee. These are unconscious responses. But conscious responses, such as catching a ball, must be honed by repeated stimulation. Adv...
