For many people, sitting back in the dentist's chair can already be a terrifying experience. But now a trip to the dentist could get a whole lot scarier as an AI-powered robot completes its first unsupervised procedure on a live human. The robot, developed by US-based company Perspective, successfully carried out a crown replacement in just 15 minutes - eight times faster than a human specialist. To carry out the procedure, the patient's mouth was first mapped with a 3D scanner before an AI planned and carried out the operation autonomously. Dr Chris Ciriello, CEO and founder of Perceptive, says: 'This medical breakthrough enhances precision and efficiency of dental procedures, and democratizes access to better dental care, for improved patient experience and clinical outcomes.'

As the era of COVID-19 persists, healthcare systems are facing a daunting range of challenges. Healthcare faculties thrive for a sustainable emergency management framework to look beyond COVID-19 and future contingency. The scientific perception of COVID-19 has been ceaselessly expanding since its outbreak. Worldwide contamination and disease progression rates, successful treatment, and speculation over potential antidote are continually fluctuating. The combination of unpredictable patterns and inadequate insight means that preparing for and executing both an instant and viable long-term pandemic response is baffling--yet undoubtedly critical for the care of patients, employees, and organizational survival. Researchers and provider organizations have increasingly embraced artificial intelligence (AI) and machine learning (ML) tools to reduce and track the spread of COVID-19 and to improve their surveillance efforts.

Driving in a busy city, you have to get good at scrutinizing the body language of pedestrians. Your foot hovers somewhere between the gas and the brake, waiting for your brain to triangulate their intent: Is that one trying to cross the street, or just waiting for the bus? Still, a whole lot of the time you hit the brakes for nothing, ending up in a kind of dance with the pedestrian (you go, no you go, no YOU go). If you think that's frustrating, then you've never been a self-driving car. As human drivers slowly go extinct (and human pedestrians don't), autonomous vehicles will have to get better at decoding those unspoken intersection interactions.
