Researcher develops new methods to measure "forever chemicals" in both the atmosphere and in aerosol particles
From regulators to researchers and most industries in between, all eyes are on PFAS. PFAS, per-and polyfluoroalkyl substances, are a class of highly fluorinated human-made compounds that have been used for decades in everything from nonstick cookware.....»»
We must stop evictions to end chronic homelessness, says researcher
Homelessness, a crisis that affects about 11% of Canadians in their lifetime, often begins with eviction. Once a person or family is evicted, they are set on a trajectory that can lead to chronic homelessness as they try to find affordable housing in.....»»

New methods to shape RNA molecules into circles could lead to more effective and long-lasting therapies, shows a study by researchers at the University of California San Diego. The advance holds promise for a range of diseases, offering a more enduri.....»»
Using machine learning to speed up simulations of irregularly shaped particles
Simulating particles is a relatively simple task when those particles are spherical. In the real world, however, most particles are not perfect spheres, but take on irregular and varying shapes and sizes. Simulating these particles becomes a much mor.....»»
US grid adds batteries at 10x the rate of natural gas in first half of 2024
By year's end, 96 percent of the US's grid additions won't add carbon to the atmosphere. (credit: DOE) While solar power is growing at an extremely rapid clip, in absolute terms, the use of natural gas for electricity pr.....»»
Chinese Gaofen-7 satellite enhances precision in forest height measurement
Scientists have developed a method to measure forest heights using advanced satellite technology, significantly reducing the need for labor-intensive fieldwork. A study published on July 29 in the Journal of Remote Sensing by a team of international.....»»
Hybrid imaging approach reveals microbes in 3D
Caltech researchers have developed a new method to create three-dimensional images of complex communities of bacteria and plant roots. The technology synthesizes two traditional methods of imaging: visualizing microbes with fluorescence and a noninva.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Rebrand, regroup, ransomware, repeat
Changes witnessed over the last few years have led to larger ransomware groups breaking into smaller units, posing more considerable challenges for law enforcement. Ransomware actors are evading arrest more easily and adapting methods with innovative.....»»
Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles......»»
What exactly are "forever chemicals"—and can we move beyond them?
The Australian parliament will conduct a national inquiry into the dangers of "forever chemicals.".....»»
Researcher explores how you can stretch your mind to grasp quantum entanglement
My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-pe.....»»
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequenc.....»»
Breaking down the indestructible: New technologies target PFAS environmental menace
PFAS are synthetic chemicals widely used in products such as non-stick cookware and waterproof clothing due to their water and grease-resistant properties. However, their persistence in the environment has led to widespread contamination and signific.....»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
The detection of individual particles and molecules has opened new horizons in analytical chemistry, cellular imaging, nanomaterials, and biomedical diagnostics. Traditional single-molecule detection methods rely heavily on fluorescence techniques, w.....»»
Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere. But a unique experiment led by Peter Reich of the University of Michigan is showi.....»»
