How can you reliably spot a fake smile? Ask a computer

Real and fake smiles can be tricky to tell apart, but researchers at the University of Bradford have now developed computer software that can spot false facial expressions. By analysing the movement of the smile across a person’s face, the software can determine whether or not the expression is genuine. The most significant movements detected

‘Alexa, monitor my heart’: Researchers develop first contactless cardiac arrest AI system for smart speakers

Almost 500,000 Americans die each year from cardiac arrest, when the heart suddenly stops beating. People experiencing cardiac arrest will suddenly become unresponsive and either stop breathing or gasp for air, a sign known as agonal breathing. Immediate CPR can double or triple someone’s chance of survival, but that requires a bystander to be present.

Artificial intelligence tool vastly scales up Alzheimer’s research: Machine learning tool automates pathologists’ work to identify disease markers

Researchers at UC Davis and UC San Francisco have found a way to teach a computer to precisely detect one of the hallmarks of Alzheimer’s disease in human brain tissue, delivering a proof of concept for a machine-learning approach to distinguishing critical markers of the disease. Amyloid plaques are clumps of protein fragments in the

Hidden control architecture of brain networks unveiled

A KAIST research team identified the intrinsic control architecture of brain networks. The control properties will contribute to providing a fundamental basis for the exogenous control of brain networks and, therefore, has broad implications in cognitive and clinical neuroscience. Although efficiency and robustness are often regarded as having a trade-off relationship, the human brain usually

E- textiles control home appliances with the swipe of a finger

Electronic textiles could allow a person to control household appliances or computers from a distance simply by touching a wristband or other item of clothing — something that could be particularly helpful for those with limited mobility. Now researchers, reporting in ACS Nano, have developed a new type of e-textile that is self-powered, highly sensitive

Synthetic ’tissues’ build themselves: Biologists program cells to self-organize into 3D-structures in a first step towards tissues that regrow and self-repair

How do complex biological structures — an eye, a hand, a brain — emerge from a single fertilized egg? This is the fundamental question of developmental biology, and a mystery still being grappled with by scientists who hope to one day apply the same principles to heal damaged tissues or regrow ailing organs. Now, in
