Ultrasound is widely used to detect breast cancer early, but misdiagnosis of benign lesions as malignant tumors sometimes leads to unnecessary biopsies. To tackle this problem, scientists conducted a large multi-center study involving 13 hospitals in China to train deep learning models to accurately classify breast masses. Their results, published in Chinese Medical Journal, showcase how artificial intelligence could find use as an assistive tool in ultrasound breast diagnosis and help alleviate workload of doctors.

Despite the continued development and commercialization of various wearable electronic devices, such as smart bands, progress with these devices has been curbed by one major limitation, as they regularly need to be recharged. However, a new technology developed by a South Korean research team has become a hot topic, as it shows significant potential to overcome this limitation for wearable electronic devices.
The Korea Institute of Science and Technology (KIST), or KIST, announced that a research team led by Director Jin-Sang Kim of the Jeonbuk Institute of Advanced Composite Materials has developed a high-efficiency flexible thermoelectric device that is capable of autonomously generating some of the electricity required for its operation from body heat. The device developed by the team features enhanced thermal insulation capabilities, made possible through the fabrication of the flexible silicone compound (PDMS) into a spo

ORLANDO, April 5, 2021 - A new study from the University of Central Florida suggests that masks and a good ventilation system are more important than social distancing for reducing the airborne spread of COVID-19 in classrooms.
The research, published recently in the journal
Physics of Fluids, comes at a critical time when schools and universities are considering returning to more in-person classes in the fall.

Could the next Hollywood blockbuster be written by a computer? Scientists from the University of Granada (UGR) and the University of Cádiz (UCA) have designed the world s first computer system based on artificial intelligence techniques that can help film scriptwriters create storylines with the best chance of box-office success.
The researchers focused their analysis on the tropes of existing films that is, the commonplace, predictable, and even necessary clichés that repeatedly feature in film plots, based on rhetorical figures. These storytelling devices and conventions enable directors to readily convey scenarios that viewers find easy to recognise.

Indoor Air provides design-based solutions on how to best use ultraviolet germicidal irradiation (UVGI) to disinfect occupied rooms without harming individuals. This research was conducted by Dorit Aviv, assistant professor of architecture and director of the Thermal Architecture Lab at the University of Pennsylvania Stuart Weitzman School of Design, Penn visiting scholar Miaomiao Hou, and Jovan Pantelic, an air quality expert at Katholieke Universiteit Leuven.
Ultraviolet germicidal irradiation (UVGI) devices use short-wavelength ultraviolet light to inactivate viruses, bacteria, and other pathogens by destroying their DNA or RNA. UV light is highly effective and has long been used to clean air and surfaces, with increased uptake in settings such as subway cars during the pandemic. However, UV light can also damage skin and eyes and must be used cautiously in occupied spaces.
