Tuning a Fundamental Material Property with an Electronic Coating
Researchers have discovered a way to tune some semiconductors to reduce the amount of energy needed to eject electrons. The approach works by placing a bilayer coating of an insulator and graphene on top of the semiconductor then applying a voltage between the semiconductor and graphene. This bilayer approach could improve the efficiency of electromechanical devices and electron accelerators. Tue, 10 Oct 2023 16:05:10 EST

FDA Establishes New Medical Device Category: FDA Authorization Now Required to Market UV Robots to Healthcare Facilities
The FDA has announced a new medical device product classification "whole room microbial reduction device" which establishes FDA regulation of UV robots intended to reduce the number of pathogens in unoccupied patient rooms, operating rooms and other areas in healthcare facilities where non-critical medical devices are present.

Pingpong Balls Score Big as Sound Absorbers
In Journal of Applied Physics, researchers describe an acoustic metasurface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation. The coupling between two resonators led to two resonance frequencies, and more resonant frequencies meant the device was able to absorb more sound. At the success of two coupled resonators, the researchers added more, until their device resembled a square sheet of punctured pingpong balls, multiplying the number of resonant frequencies that could be absorbed.

Sweet Victory: Sensor Detects Adulteration in Honey
In Review of Scientific Instruments, scientists developed a microwave microstrip line planar resonator sensor tool to detect water adulteration in honey. The tool is compact, cost-effective, and easily fabricated. The microstrip line resonator sensor is fabricated on a dielectric substrate, which is an insulator that can efficiently support electrostatic fields, such as ceramic or glass. The team tested honey samples with varying water content and found that the sensor's resonance frequency consistently decreases with increased added water content. Tue, 10 Oct 2023 11:00:00 EST

NASA's Webb Captures an Ethereal View of NGC 346
Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth - NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely by a variety of telescopes. NASA's Hubble Space Telescope showed a visible-light view filled with thousands of stars. More recently, NASA's James Webb Space Telescope offered a near-infrared vista highlighting both cool and warm dust. Now, Webb has turned its mid-infrared gaze to NGC 346, revealing streamers of gas and dust studded with bright patches filled with young protostars. Tue, 10 Oct 2023 10:05:57 EST

Study: Wild pig populations in U.S. can be managed
Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research from the University of Georgia's Savannah River Ecology Laboratory and Warnell School of Forestry and Natural Resources. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.

Wireless, battery-free electronic 'stickers' gauge forces between touching objects
UC San Diego engineers developed electronic "stickers" that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces, making them versatile for a wide range of applications, from surgical robots to smart implants and inventory tracking.

Сoconut shell made concrete more durable
Scientists have found that concrete's compressive strength can be increased by 4,1% and its flexural strength by 3,4% by adding a small amount of coconut shell (only 5%). In doing so, the material's performance increased by 6,1% compared to clear concrete. Tue, 10 Oct 2023 03:05:38 EST

Scientists have described molecular composition of connective tissue of echinoderms.
Biologists have analyzed about 200 articles dedicated to composition of connective tissue (Extracellular Matrix) of echinoderms. That has enabled them for the first time to compare the composition of extracellular matrix of echinoderms and vertebrates. Tue, 10 Oct 2023 02:05:39 EST

Climate-driven extreme heat may make parts of Earth too hot for humans
If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves. Mon, 09 Oct 2023 18:05:57 EST

Newly-discovered "margarita snails" from the Florida Keys are bright lemon-yellow
The "Margaritaville" in Jimmy Buffett's famous song isn't a real place, but it's long been associated with the Florida Keys. This string of tropical islands is home to the only living coral barrier reef in the continental US, along with many animals found nowhere else in the world. Mon, 09 Oct 2023 18:05:51 EST

Tropical ecosystems more reliant on emerging aquatic insects, study finds, potentially putting them at greater risk
A team of researchers from Queen Mary University of London and the University of Campinas in Brazil has found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems and are therefore more vulnerable to disruptions to the links between land and water.

Plate tectonic surprise: Utrecht geologist unexpectedly finds remnants of a lost mega-plate
Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. Her colleagues in Utrecht had predicted its existence over 10 years ago based on fragments of old tectonic plates found deep in the Earth's mantle. Mon, 09 Oct 2023 18:05:36 EST
