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.....»»
AMD adaptive computing technology enables next-gen Denso LiDAR system
AMD announced recently that its adaptive computing technology is powering Denso's next-generation LiDAR platform to deliver over 20X improvement in resolution with extremely low latency for increased precision in detecting pedestrians, vehicles, free.....»»
Instrument on JWST has gone offline
The JWST is having a problem. One of its instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS), has gone offline. The NIRISS performs spectroscopy on exoplanet atmospheres, among other things......»»
Colorado lawmakers look to AI to detect wildfires early
A year after the most destructive wildfire in the state's history scorched nearly 1,100 homes, Colorado lawmakers are considering joining other Western states by adopting artificial intelligence in hopes of detecting blazes before they burn out of co.....»»
Were galaxies much different in the early universe?
An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting "cosmic dawn"—the era after the Big Bang when stars first ignited and galaxies began to bloom......»»
Researchers create a low-cost sensor that detects heavy metals in sweat
Heavy metals such as lead and cadmium are present in batteries, cosmetics, food and other things that are part of everyday life. They are toxic when they accumulate in the human organism, potentially causing several health problems, but detecting the.....»»
Modified CRISPR-based enzymes improve the prospect of inserting entire genes into the genome
Many genetic diseases are caused by diverse mutations spread across an entire gene, and designing genome editing approaches for each patient's mutation would be impractical and costly......»»
Genetically modified rice could be key to tackling food shortages caused by climate change
As sea levels rise as a result of climate change, more and more places around the world are struggling with seawater inundation—where salt water from the sea is flooding further inland and destroying crops which can't cope with the increased salini.....»»
Raman spectroscopy method for rapid identification of beer spoilage bacteria
In a study published in Analytical Methods, a research group led by Li Bei from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) proposed the rapid detection of beer spoilage bacteria base.....»»
Radiation build-up and dissipation in Raman random fiber laser
Raman random fiber lasers (RRFL) have attractive features, such as their simple structure, excellent wavelength-tunability and high optical-optical conversion efficiency. They show great potential for long-distance fiber sensing, speckle-free imaging.....»»
Dridex banking malware modified to spread using macOS
A variant of the Dridex banking malware is using macOS to spread to others, by using email attachments that look like regular documents.Dridex targets MacsSecurity researchers at Trend Micro said on Thursday that the malware previously targeted Windo.....»»
Nanoplastics unexpectedly produce reactive oxidizing species when exposed to light
Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make their way into the oceans, where they take up to hundreds of years to break down i.....»»
Study creates new open-access database to better identify plastic pollution sources
Research led by the Monterey Bay Aquarium and MBARI (Monterey Bay Aquarium Research Institute) provides a new open-access Raman spectral library that can be used to detect molecular "fingerprints" of particles and better trace sources of ocean plasti.....»»
New spectroscopy technique improves trace element detection in liquid
Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis technology that has been well developed for trace element analyses in gases, liquids, and solids. It uses a high-power laser pulse to elicit short-lived, high-temperature plasma.....»»

OtterBox is taking on PopSockets with an innovative new case with a built-in grip that retains support for MagSafe.OtterGrip cases by OtterBoxThe new OtterGrip case debuted at CES 2023 and is a modified version of the popular OtterBox Symmetry line......»»
New measurements of galaxy rotation lean toward modified gravity as an explanation for dark matter
Although dark matter is a central part of the standard cosmological model, it's not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that scientists have found no direct particle evidence.....»»
New York governor signs modified right-to-repair bill at the last minute
Bill passed the state legislature with overwhelming majorities over the summer. Enlarge (credit: Getty) New York state governor Kathy Hochul has signed the Digital Fair Repair Act into law, months after it had passed bot.....»»
India"s switch to GM food crops hinges on court verdict
Whether India—the world's second-largest producer of staples like rice and wheat as well as fruits and vegetables—finally switches to genetically modified (GM) food crops hinges on litigation currently being fought in the country's supreme court.....»»
Deep learning can predict tsunami impacts in less than a second
Detailed predictions about how an approaching tsunami will impact the northeastern coastline in Japan can be made in fractions of a second rather than half an hour or so—buying precious time for people to take appropriate action. This potentially l.....»»
Male wasps use genitalia to sting their predators
Female bees and wasps use modified ovipositors, formerly used in egg laying, to sting their attackers, including people. Now, a study in Current Biology on December 19 shows that male mason wasps use sharp genital spines to attack and sting predatory.....»»
Study uncovers existing limitations in the detection of entanglement
Quantum entanglement is a process through which two particles become entangled and remain connected over time, even when separated by large distances. Detecting this phenomenon is of crucial importance for both the development of quantum technology a.....»»
