Spiropyran-functionalized photochromic nylon webbings for long-term ultraviolet light sensing
Webbing structures—from chin straps and parachute material to space habitats—are extensively employed in engineering systems as load-bearing components. They are frequently subjected to extended ultraviolet (UV) light irradiation, which can affec.....»»
An upgrade for magnetic resonance methods with a 1,000-fold amplifier
Researchers determine the structure and dynamics of proteins using NMR (Nuclear Magnetic Resonance) spectroscopy. Until now, however, much higher concentrations were necessary for in-vitro measurements of the biomolecules in solution than found in ou.....»»
How to change mouse DPI on PC
DPI controls the sensitivity associated with a computer mouse. There are numerous reasons why you’d want to change a mouse’s DPI, and we'll show you how......»»
Advanced pure copper 3D printing with sub-micron resolution
High-quality data transmission, high-precision information sensing, and high-sensitivity signal detection are important means to achieve precise perception and effective identification. High-performance chips, terahertz transmission T/R components, a.....»»
Underlying microbial mechanisms driving temperature sensitivity of soil respiration vary by season
The intensity of soil respiration increases with temperature on a global scale. Temperature sensitivity of soil respiration, usually termed as Q10, is defined as the increase in CO2 efflux for a 10°C increase in temperature. In many traditional ecos.....»»
Solar storm to hit Earth"s magnetic field on July 21
Something is happening to the sun. One of the regions of the solar atmosphere currently exhibiting sunspots caught the attention of observatories on July 11, when there was a sudden increase in ultraviolet and X-ray brightness. The next ones to notic.....»»
Typhoid Detection Technique Improves Diagnostic Sensitivity
A team at the University of California Davis Health working with international collaborators have developed a new technique to detect typhoid and estimate its incidence in populations over time. The approach requires only a drop of blood from a finge.....»»
Artificial intelligence folds RNA molecules
For the function of many biomolecules, their three-dimensional structure is crucial. Researchers are therefore not only interested in the sequence of the individual building blocks of biomolecules, but also in their spatial structure. With the help o.....»»
Revealing atomistic structures behind AFM imaging
Atomic force microscopy (AFM) allows us to visualize the dynamics of single biomolecules during their functional activity. All observations are, however, restricted to regions accessible by a fairly big probing tip during scanning. Hence, AFM images.....»»
Photonic synapses with low power consumption and high sensitivity
Neuromorphic photonics/electronics is the future of ultralow energy intelligent computing and artificial intelligence (AI). In recent years, inspired by the human brain, artificial neuromorphic devices have attracted extensive attention, especially i.....»»
Investigating the temperature of large biomolecules in ion-storage rings using jellyfish protein
New research introduces a simple way to determine the temperature of a stored biomolecule and assess how it changes overtime......»»
Scientists map sulfur residue on Jupiter"s icy moon Europa
A Southwest Research Institute-led team used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a "gap" in the various wavelengths used to observe this icy water world. The team's near-global UV maps.....»»
Research finds evidence to suggest Pacific whiting skin has anti-aging properties that prevent wrinkles
The gelatin in the skin of Pacific whiting, an abundant fish on the Pacific Coast of North America, may help prevent skin wrinkling caused by ultraviolet radiation, a new Oregon State University study found......»»
Thousands of galaxies shine in ultraviolet light in new Hubble image
A new image from NASA's Hubble Space Telescope is brimming with distant galaxies in an assortment of shapes. Some are seen face-on and appear oval or as disks or spirals, while others are seen edge-on and look more like cigars. The new image differs.....»»
Determining which wavelengths of UV light work best for COVID-19 virus disinfection
To disinfect a surface, you can illuminate it with a blast of ultraviolet (UV) light, which is bluer than the human eye can see. But to specifically inactivate SARS-CoV-2, the virus that causes COVID-19, which wavelengths are best? And how much radia.....»»
