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.....»»
Photoacoustic sensor achieves high-sensitivity detection of multiple greenhouse gases
Recently, Prof. Gao Xiaoming's team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a novel photoacoustic spectroscopy (PAS)-based sensor that enabled simultaneous, high-sensitive detection of CO2, CH4, and.....»»
Could you find what a lunar crater is made of by shooting it?
Americans are famously fond of their guns. So it should come as no surprise that a team of NASA scientists has devised a way to "shoot" a modified type of sensor into the soil of an otherworldly body and determine what it is made out of. That is prec.....»»
Apple Watch Series 10 review: Ultra inspired, mainstream desired, equilibrium acquired
For the last week, I’ve been testing the new Apple Watch — mostly by sleeping. That’s because Apple Watch Series 10 is capable of detecting signs of sleep apnea. I’ll need a few more weeks of sleep before possible sleep apnea can be flagge.....»»
Bridging large riverine ecosystems for inter-basin exchanges
Many of the world's large rivers have been modified to support food security, hydropower production, navigation and trade. While these developments are necessary to support a growing human population, they also pose substantial risks to the structure.....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Three Apple Watches get FDA approval for sleep apnea detection, from today
Three Apple Watches have received approval for detecting sleep apnea, just in time for today’s launch of the feature in watchOS 11. The Federal Drug Administration approval was able to be granted swiftly on the basis that the way Apple is doing.....»»
Researchers develop novel covalent organic frameworks for precise cancer treatment delivery
A team of researchers at NYU Abu Dhabi (NYUAD), led by Program Head of Chemistry Ali Trabolsi, have developed nanoscale covalent organic frameworks (nCOFs), crystalline organic polymers that have been modified with peptides to treat the most aggressi.....»»
Toyota has repair for Grand Highlander, Lexus TX after lengthy stop-sale
A costly and disruptive stop-sale to Toyota's large three-row crossovers is expected to end in late October after Toyota determined that modified side-curtain airbags will bring the vehicles back into compliance......»»
Neural network improves tunable diode laser absorption spectroscopy quantification accuracy
A research group from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences recently developed a neural network-based absorbance recovery method to improve the accuracy of single path tunable diode laser absorption spect.....»»
NMR spectroscopy method provides faster way to determine chiral structure of molecules
Researchers from Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH have developed a new method that allows, for the first time, the elucidation of the chiral structure of molecules—the exact spatial arrangement of the atoms—by nuclear ma.....»»
How human-led threat hunting complements automation in detecting cyber threats
In this Help Net Security interview, Shane Cox, Director, Cyber Fusion Center at MorganFranklin Consulting, discusses the evolving methodologies and strategies in threat hunting and explains how human-led approaches complement each other to form a ro.....»»
Alien Spaceships Could Be Detected Using Gravitational Waves
The concept of space-time makes Star Trek-style warp drives theoretically possible, and researchers have proposed a way of detecting their use......»»
3D imaging allows researchers to observe degradation of micro- and nanoplastics with unprecedented detail
In a global first, University of Waterloo researchers have used 3D imaging technology to understand the fine details of microplastics, paving the way for more effective methods of plastic waste recycling......»»
Researchers develop molecular biosensors that only light up upon binding to their targets
Biosensors—devices that use biological molecules to detect the presence of a target substance—have enormous potential for detecting disease biomarkers, molecules-in-action in diverse biological processes, or toxins and other harmful substances in.....»»
Saturday Citations: Corn sweat! Nanoplastics! Plus: Massive objects in your area are dragging spacetime
It's the last day of August, which means that in the Northern Hemisphere, tomorrow will be 50 degrees and cloudy; conditions are expected to be hot and humid south of the equator. In science news this week, we reported on nanoplastic contamination, s.....»»
Nanoplastics put stress on trees and impair photosynthesis
It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro- and nano-sized particles. It remains unclear how and to what extent they are able to enter living org.....»»
Spectroscopy study reveals electrons in cocatalyst periphery drive photocatalytic hydrogen evolution
Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT–IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydroge.....»»
Researchers develop near-infrared spectroscopy models to analyze corn kernels and biomass
In the agricultural and food industry, determining the chemical composition of raw materials is important for production efficiency, application, and price. Traditional laboratory testing is time-consuming, complicated, and expensive. New research fr.....»»
