Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
The LIFE telescope passed its first test, detecting biosignatures on Earth
We know that there are thousands of exoplanets out there, with many millions more waiting to be discovered. But the vast majority of exoplanets are simply uninhabitable. For the few that may be habitable, we can only determine if they are by examinin.....»»
Novel method improves Fourier transform infrared spectroscopy detection of ultra-low concentration trace substances
Recently, a research team led by Prof. Gao Minguang and Associate Prof. Li Xiangxian from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) has developed a spectral resolution enhancement method based on linear predictio.....»»
Ultraviolet spectroscopy: A leap in precision and accuracy at extremely low light levels
Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, quantum-electrodynamics theory, determination of fun.....»»
The role of PbrChiA chitinase in ROS regulation and antifungal activity
Pear ring rot, a significant threat to pear production, is caused by Botryosphaeria dothidea, leveraging the complex dynamics of reactive oxygen species (ROS) during infection. Initially, plants employ their innate immune system, detecting pathogens.....»»
A new type of metallacrown ether based on polyoxometalate opens research opportunities
Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit, creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research. Depending on the molecular makeup of the metallacrow.....»»
Scientists improve timing of fog warnings by detecting changes in atmospheric electric field
A foggy day in London town just got even more predictable. Scientists have discovered how to increase early warnings for fog, from around half an hour to up to two hours before it happens, by detecting changes in the atmospheric electric field......»»
New method measures levels of toxic tire particles in rivers
Scientists at the UK Centre for Ecology & Hydrology (UKCEH) have developed a robust method for detecting whether a toxic chemical used in car tires is present in rivers, streams, and lakes and measuring its concentrations......»»
Electrons become fractions of themselves in graphene, study finds
The electron is the basic unit of electricity, as it carries a single negative charge. This is what we're taught in high school physics, and it is overwhelmingly the case in most materials in nature......»»
Detecting atmospheric rivers with satellite observations
Atmospheric rivers (ARs) are filaments of intense moisture transport in the atmosphere. These weather systems drive a large fraction of the extreme precipitation events over coastal regions. Detecting ARs in satellite observations has long been a cha.....»»
Unlocking the full potential of Auger electron spectroscopy
Auger electron spectroscopy (AES) is an incredibly useful technique for probing material samples—but current assumptions about the process ignore some of the key time-dependent effects it involves. So far, this has resulted in overly-simplified cal.....»»
A modified Galaxy Z Fold 2 was used to test the Pixel Fold software
It seems that when developing the Pixel Fold, Google used a modified version of the Samsung Galaxy Z Fold 2 as a testing device. The post A modified Galaxy Z Fold 2 was used to test the Pixel Fold software appeared first on Phandroid. The.....»»
Hugging Face empowers users with deepfake detection tools
Hugging Face released a collection of tools for watermarking and detecting AI-generated content. Hugging Face wants to help users fight back against AI deepfakes. The company that develops machine learning tools and hosts AI projects also offer.....»»
Passing stars altered orbital evolution of Earth and other planets, astronomers find
Stars that pass by our solar system have altered the long-term orbital evolution of planets, including Earth, and, by extension, modified our climate......»»
More references to a new HomePod with a screen found in tvOS 17.4 beta
We’ve been hearing rumors about Apple’s future plans for the HomePod, and 9to5Mac reported last year that the company has been internally running tvOS on a modified iPad mini to see how a new HomePod with a built-in display would work. With tvOS.....»»
Couple credits Apple Watch for detecting silent heart condition requiring medical intervention
Apple Watch added atrial fibrillation detection several years ago, and customers have benefited from the feature ever since. The latest example of making a difference comes from a couple out of Summerville, South Carolina. more….....»»
Meet NASA"s twin spacecraft headed to the ends of the Earth
Two new miniature NASA satellites will start crisscrossing Earth's atmosphere in a few months, detecting heat lost to space. Their observations from the planet's most bone-chilling regions will help predict how our ice, seas, and weather will change.....»»
New research with implications for drug discovery makes it possible to visualize the smallest protein clusters
Penn Engineers have pioneered a new way to visualize the smallest protein clusters, skirting the physical limitations of light-powered microscopes and opening new avenues for detecting the proteins implicated in diseases like Alzheimer's and testing.....»»
When nanoplastics are not what they seem: Release of oligomers from polyester textiles
Plastic household items and clothing made of synthetic fibers release microplastics, particles less than five millimeters in size that can enter the environment unnoticed. A small proportion of these particles are so small that they are measured in n.....»»
New findings from JWST: How black holes switched from creating to quenching stars
Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope's infrared detecting "eyes" have spotted an array of small, red dots, identi.....»»
