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.....»»
Watching SARS-CoV-2 spread in animal models in real time
A version of SARS-CoV-2, the virus that causes COVID-19 disease, has been successfully modified to glow brightly in cells and animal tissues, providing a real-time way to track the spread and intensity of viral infection as it happens in animal model.....»»
Researchers develop new method for detecting superfluid motion
Researchers at Rochester Institute of Technology are part of a new study that could help unlock the potential of superfluids—essentially frictionless special substances capable of unstopped motion once initiated. A team of scientists led by Mishkat.....»»
Ultrasensitive detection of endocrine disruptors via superfine plasmonic spectral combs
The apparent increase in hormone-induced cancers and disorders of the reproductive tract has led to a growing demand for new technologies capable of detecting nanogram per liter level endocrine disruptors. Scientists in China invented an ultracompact.....»»

New way to probe exotic matter aids in the study of atomic and particle physics
Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light shining on a sample over time to reveal details about.....»»
Uncovering fragmentation differences in chiral biomolecules
By combining mass spectroscopy with further analytical and simulation techniques, researchers have revealed key differences in the fragmentation of dipeptide biomolecules with different chiral structures......»»
Buildots raises $30M to put eyes on construction sites
Buildots' technology automatically validates images captured by hardhat-mounted 360-degree cameras, detecting any gaps between the original design and what's actually happening on construction sites. One year after raising $16 million, cons.....»»
Scientists boost gene knockdown in human cells with CRISPR-Cas13 using chemically modified guide RNAs
In the latest of ongoing efforts to expand technologies for modifying genes and their expression, researchers in the lab of Neville Sanjana at New York University (NYU) and the New York Genome Center (NYGC) have developed chemically modified guide RN.....»»
Amplified spontaneous emission source in a co-pumping, single-frequency Raman fiber amplifier
Recently, researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences (CAS) have provided the new idea of co-pumping single-frequency Raman amplifiers. Relevant result was published in Optics Express.....»»
Oova raises $1.2M to develop a better at-home kit for detecting a woman’s best time to conceive
Oova officially launched its Oova Kit that includes an at-home test that quantitatively measures two hormones, informing a woman — and her doctor — of her fertile days and confirming ovulation. Oova officially launched its Oova Kit Tues.....»»
Police Are Telling ShotSpotter To Alter Evidence From Gunshot-Detecting AI
An anonymous reader quotes a report from Motherboard: On May 31 last year, 25-year-old Safarain Herring was shot in the head and dropped off at St. Bernard Hospital in Chicago by a man named Michael Williams. He died two days later. Chicago police ev.....»»
Novel SERS strategy developed for beta-galactosidase activity assay
Recently, a research group led by Prof. Yang Liangbao from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) developed in-situ Surface-enhanced Raman spectroscopy (SERS) readout strategy to improve the reliabil.....»»
Mycoplasma mobile moves into overdrive: Twin motor modified from ATP synthase discovered
For more than 20 years, Makoto Miyata from Osaka City University has been studying the gliding motility of the parasitic bacterium Mycoplasma mobile (M. mobile). It is a mechanism consisting of an external "grabbing" structure and internal "motor"—.....»»
Amazon Asked Apple To Remove an App That Spots Fake Reviews, and Apple Agreed
Apple has removed Fakespot, a well-known app for detecting fake product reviews, from its App Store after Amazon complained the app provided misleading information and potential security risks. From a report: Fakespot's app works by analyzing the cre.....»»
A bug"s life: Millimeter-tall mountains on neutron stars
New models of neutron stars show that their tallest mountains may be only fractions of millimeters high, due to the huge gravity on the ultra-dense objects. The research is presented today at the National Astronomy Meeting 2021......»»
Modified yeast inhibits fungal growth in plants
About 70–80% of crop losses due to microbial diseases are caused by fungi. Fungicides are key weapons in agriculture's arsenal, but they pose environmental risks. Over time, fungi also develop a resistance to fungicides, leading growers on an endle.....»»
Detecting wildlife illness and death with new early alert system
