The leading cause of death in Texas is heart disease, according to the National Center for Health Statistics, accounting for more than 45,000 deaths statewide in 2017. A new wearable technology made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines -- a technology that has changed little in almost a century.
Microscopy just got reinvented - again. Traditionally, scientists have used light, x-rays, and electrons to peer inside tissues and cells. Today, scientists can trace thread-like fibers of nerves throughout the brain and even watch living mouse embryos conjure the beating cells of a rudimentary heart.
Researchers at the University of Maryland have captured the most direct evidence to date of a quantum quirk that allows particles to tunnel through a barrier like it's not even there. The result, featured on the cover of the June 20, 2019 issue of the journal Nature, may enable engineers to design more uniform components for future quantum computers, quantum sensors and other devices.
Katsushika Hokusai (1760 - 1849) is the Titan of Japanese art, as revered in his homeland as Da Vinci, Van Gogh, and Rembrandt Van Rijn are in the West. Of all his famed masterpieces the 'Great Wave' stands out as the ultimate testament to his artistic genius.
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.
A wearable non-invasive device based on near-infrared spectroscopy (NIRS) can be used to investigate blood volume and oxygenation patterns in freely diving marine mammals, according to a study publishing June 18 in the open-access journal PLOS Biology by J. Chris McKnight of the University of St. Andrews, and colleagues.
The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those water droplets are uniform in their size and spacing, bubble formation is typically a much more random process.
A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), report scientists from the Okinawa Institute of Science and Technology Graduate University (OIST). Adding a "self-healing" polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.
A hair-sized probe that can measure key indicators of tissue damage deep in the lung has been developed by scientists. The new technology could pave the way for accurate monitoring of tissue in areas where existing technologies cannot reach.
Most people think of water as existing in only one of three phases: Solid ice, liquid water, or gas vapor. But matter can exist in many different phases--ice, for example, has more than ten known phases, or ways that its atoms can be spatially arranged. The widespread use of piezoelectric materials, such as microphones and ultrasound, is possible thanks to a fundamental understanding of how an external force, like pressure, temperature, or electricity, can lead to phase transitions that imbue materials with new properties.
Using sound vibrations and pulses of near-infrared light, a Rutgers University scientist has developed a new "virtual biopsy" device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.
HOUSTON -- (June 12, 2019) -- Using rare oxygen molecules trapped in air bubbles in old ice and snow, U.S. and French scientists have answered a long-standing question: How much have "bad" ozone levels increased since the start of the Industrial Revolution?
University of Colorado Boulder researchers have developed nano bio-hybrid organisms capable of using airborne carbon dioxide and nitrogen to produce a variety of plastics and fuels, a promising first step toward low-cost carbon sequestration and eco-friendly manufacturing for chemicals.
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and blinking light to the matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
While dark matter abounds in the universe - it is by far the most common form of matter, making up about 85 percent of the universe's total - it also hides in plain sight. We don't yet know what it's made of, though we can witness its gravitational pull on known matter.
