A face-following robot arm with emotion detection

Researchers at Universitat Autònoma de Barcelona (UAB) have recently developed a face-following robotic arm with emotion detection inspired by Pixar Animation Studios' Luxo Jr. lamp. This robot was presented by Vernon Stanley Albayeros Duarte, a computer science graduate at UAB, in his final thesis.

What do they mean by 'stem cells'? Recommended guidelines for reporting on cell therapies

Cell therapies including so-called "stem cells" are increasingly being marketed and used for the treatment of musculoskeletal disorders - despite questions about these treatments and their effectiveness. A new tool for standardizing communication about cell therapies is presented in the May 15 issue of The Journal of Bone & Joint Surgery.

Preventive measures can reduce foot parasite in children, study says

Tungiasis is a neglected tropical disease caused by penetrated sand fleas which burrow into the skin of the feet. Public health policies such as sealing house and classroom floors and daily feet washing with soap could cut the number of tungiasis cases in school-aged children, researchers now report in PLOS Neglected Tropical Diseases.

CosmoGAN: Training a neural network to study dark matter

As cosmologists and astrophysicists delve deeper into the darkest recesses of the universe, their need for increasingly powerful observational and computational tools has expanded exponentially. From facilities such as the Dark Energy Spectroscopic Instrument to supercomputers like Lawrence Berkeley National Laboratory's Cori system at the National Energy Research Scientific Computing (NERSC) facility, they are on a quest to collect, simulate, and analyze increasing amounts of data that can help explain the nature of things we can't see, as well as those we can.

Designing biological movement on the nanometer scale

Synthetic proteins have been created that move in response to their environment in predictable and tunable ways. These motile molecules were designed from scratch on computers, then produced inside living cells.

Framework improves 'continual learning' for artificial intelligence

Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while "forgetting" less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.

Balancing the beam: Thermomechanical micromachine detects terahertz radiation

Radiation from many parts of the electromagnetic spectrum has been harnessed for extremely beneficial uses, in fields as diverse as medicine, imaging and photography, and astronomy. However, the terahertz (THz) region of the spectrum, situated between microwaves and infrared light, has been relatively underutilized owing to difficulties in generating such radiation artificially and in building devices to detect it.

Drexel-developed safety climate scale helps fire departments reach safety goals

A new safety scale, that effectively measures the safety climate of a fire department, has been developed by researchers from Drexel's Dornsife School of Public Health, according to a paper published today in the journal Safety Science. The tool helps fire departments gauge their management and supervisor support for safety initiatives that prevent burnout, poor engagement and low job satisfaction—all attributes that many previous studies have shown can increase injuries and deaths in the line of duty.

Leveraging information technology to address health disparities

Disparities in health care delivery and health outcomes present distressing challenges to underserved populations, who often experience a greater burden of chronic diseases and are more likely to show signs of poor disease management. Health information technology (IT) tools may serve a vital role in reducing such disparities in the clinical care setting. In the Medical Care June supplement, "Addressing Health Disparities Through the Utilization of Health Information Technology," authors discuss the potential application of health IT in reducing disparities by increasing access to care, improving quality of healthcare and by promoting better patient-clinician communication.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Ex-Tropical Cyclone Ann moving over Australia's Cape York Peninsula

NASA-NOAA's Suomi NPP satellite passed over the Southern Pacific Ocean and captured a visible image of the remnants of Tropical Cyclone Ann moving over Queensland's Cape York Peninsula. Despite the storm weakening below tropical cyclone status, warnings remain active for strong winds and flooding potential.
