Scientists have identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. NASA’s Parker Solar Probe is venturing closer to the Sun than any previous probe. Scientists are probing the enigmatic features of the Sun to answer many questions, including how to protect space travelers and technology…

Researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer…

Black holes and neutron stars are some of the most extreme objects in the Universe, ripping up neighboring stars. But they are messy eaters and much of they take in gets flung back into space. Scientists have now observed a neutron star blasting out warm and cold wind as it devoured another star. The findings…

This shirt harvests and stores energy from the human body to power small electronics. UC San Diego nanoengineers call it a »wearable microgrid»— it combines energy from the wearer’s sweat and movement to provide sustainable power for wearable devices. The technology, reported in a paper published Mar. 9 in Nature Communications, draws inspiration from community…

Researchers have developed a new approach in which robotic exosuit assistance can be calibrated to an individual and adapt to a variety of real-world walking tasks in a matter of seconds. The bioinspired system uses ultrasound measurements of muscle dynamics to develop a personalized and activity-specific assistance profile for users of the exosuit. This human…

Virtual reality avatar-based coaching shows promise to increase access to and extend the reach of nutrition education programs to children at risk for obesity, according to a new study. Researchers introduced 15 adult-child dyads to a virtual avatar-based coaching program that incorporated age-specific information on growth; physical, social, and emotional development; healthy lifestyles; common nutrition…

A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD). «Dogs share many similarities with humans, including physiological traits and the same environment. In addition, ADHD-like behaviour naturally occurs…

A team of researchers working with data collected by an Incoherent Scatter Radar (ISR) have examined the simultaneous impacts of thunderstorms and solar flares on the ionospheric D-region (often referred to as the edge of space). A team of researchers working with data collected by the Incoherent Scatter Radar (ISR) at the Arecibo Observatory, satellites,…

The behaviour of one of nature’s humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe. In shaping the Universe, gravity builds a vast cobweb-like structure of filaments tying galaxies and clusters of galaxies together along invisible bridges of gas and dark matter hundreds…

Archaeologists have provided important new evidence to answer the question ‘who exactly were the Anglo-Saxons?’ New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe. New findings based on studying skeletal remains clearly…
