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.....»»
Future Apple update will allow third parties to replace iPhone 13 screens without breaking Face ID
Apple, long known for its opposition to the right to repair movement, attracted more controversy recently when iFixit confirmed that using an independent repair shop to replace the screen on an iPhone 13 renders Face ID useless. Upon detecting a new.....»»

A modified consumer drone was used in an attack on an electrical substation in the US last year, according to a report from the FBI, Department of Homeland Security and National Counterterrorism Center. New Scientist reports: The report, which is bei.....»»
Study reveals allocation patterns of foliar-P fractions of Alhagi sparsifolia in different P availability soils
Researchers from the Xinjiang Institute of Ecology and Geography (XIEG) of the Chinese Academy of Sciences found that foliar-phosphorus (P) fractions of Alhagi sparsifolia changed with different P availability soils......»»
New study proposes expansion of the universe directly impacts black hole growth
Over the past 6 years, gravitational wave observatories have been detecting black hole mergers, verifying a major prediction of Albert Einstein's theory of gravity. But there is a problem—many of these black holes are unexpectedly large. Now, a tea.....»»
Using neutrons to analyze modified high-entropy metal alloys
Researchers at Oak Ridge National Laboratory have developed a method of adding nanostructures to high-entropy metal alloys, or HEAs, that enhance both strength and ductility, which is the ability to deform or stretch under tensile stress without fail.....»»
New methods for detecting single molecules
Resistance to antibiotics is on the rise worldwide. Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM alongside the Ludwig Maximilian University of Munich have developed a process for rapidly detecting multidrug-resistan.....»»
Nanoplastics found in the Alps were transported by air from Frankfurt, Paris and London
A team of researchers have found nanoplastics at the pristine high-altitude Sonnblick Observatory in the Alps. This is the first time that nanoplastics have been found in this area. The researchers were originally looking for certain organic particle.....»»
A new strategy for detecting non-conformist particles called anyons
A team of Brown University researchers has shown a new method of probing the properties of anyons, strange quasiparticles that could be useful in future quantum computers......»»
One plus one does not equal two: Research team investigates receptors that form pairs on the surface of cells
There are a number of G protein-coupled receptors in human cells. As an important component of the cell membrane, these proteins are responsible for detecting different stimuli in the surroundings of a cell within the body and transferring this infor.....»»
Photon-counting distributed free-space spectroscopy
Remote sensing of atmospheric gas plays an important role in the fields of greenhouse gas monitoring, toxic, harmful, flammable, explosive gasses, and biochemical weapons early warning. With the advent of quantum mechanics and lasers, precise spectra.....»»
NEID spectrometer lights up path to exoplanet exploration
A new NASA instrument will look for planets by detecting subtle wobbles from their parent stars. To prepare, it will study the sun......»»
New MOND theory able to account for cosmic microwave background
A pair of researchers at the Czech Academy of Sciences has been shaking up the astrophysics community with a new modified Newtonian dynamics (MOND) theory that tosses out the concept of dark matter and instead backs up theories that suggest there is.....»»
Scientists develop new sensor to capture calcium activity in cells
A team of researchers at Georgia State University has developed a novel approach for detecting the activity of calcium within cells. The study, led by Regents' Professor of Chemistry Jenny Yang, demonstrates the effectiveness of a red biosensor that.....»»
Uncovering the secrets of ultra-low frequency gravitational waves
New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according to researchers at the University of Birmingham......»»
Surface chemistry reveals corrosive secrets
One can easily see with the naked eye that leaving an old nail out in the rain causes rust. What does require the keen eyes and sensitive nose of microscopy and spectroscopy is observing how iron corrodes and forms new minerals, especially in water w.....»»
Researchers create earthquake system model with better detection capabilities
Two University of Wyoming researchers have developed a machine learning model that improves the accuracy of detecting earthquakes by 14.5 percent compared to the most accurate current existing model......»»
An efficient and low-cost approach to detecting food fraud
Fraudulent practices in food production, especially false claims of geographical origin, cause billions of dollars in economic damage every year. Botanists at the University of Basel have now developed a model that can be used to determine the origin.....»»
