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.....»»
People given "friendly" bacteria in nose drops protected against meningitis, study suggests
A recent trial has shown that nose drops of modified 'friendly' bacteria may protect against meningitis......»»
A novel forensic tool for detecting laundering of critically endangered cockatoos
Ecologists from the Conservation Forensics Laboratory of the Research Division for Ecology and Biodiversity at the University of Hong Kong (HKU) have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-ca.....»»
Could ketogenic diet be helpful with brain cancer?
A modified ketogenic diet may be worth exploring for people with brain tumors, according to a new study. The small study found that the diet was safe and feasible for people with brain tumors called astrocytomas. The study was not designed to determi.....»»
Microscopy technique makes finer images of deeper tissue, more quickly
A team of researchers has developed a modified version of two-photon imaging that can scan deeper within tissue and perform the imaging much faster than previously possible......»»
Dataminr’s first ever acquisition is UK-based geovisualization platform WatchKeeper
When it comes to detecting events transpiring anywhere in the world, few companies hold a candle to Dataminr. Founded in 2009, the company has raised more than $1 billion over the past 12 years (including $475 million at a $4.1 billion valuation just.....»»
Imaging spectroscopy can predict water stress in wild blueberry fields, says study
Imaging spectroscopy can help predict water stress in wild blueberry barrens, according to a University of Maine-led study......»»
New approach can add diversity to crop species without breeding GMOs
Breeding better crops through genetic engineering has been possible for decades, but the use of genetically modified plants has been limited by technical challenges and popular controversies. A new approach potentially solves both of those problems b.....»»
Researchers hone in on the best software for detecting microRNAs in plants
Almost twenty years ago, the process of RNA silencing was discovered in plants, whereby small fragments of RNA inactivate a portion of a gene during protein synthesis. These fragments—called microRNAs (abbreviated as miRNAs)—have since been shown.....»»
Frequent COVID-19 testing key to efficient, early detection, study finds
The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98 percent.....»»
Microfilter device capable of detecting trace amounts of cancer cells in one mL of blood
Researchers have developed a microfilter device that can easily separate and capture trace amounts of cancer cells in blood. The palm-sized device is expected to contribute to the development of new cancer diagnostic technologies based on cancer cell.....»»
Hunting dark energy with gravity resonance spectroscopy
Dark Energy is widely believed to be the driving force behind the universe's accelerating expansion, and several theories have now been proposed to explain its elusive nature. However, these theories predict that its influence on quantum scales must.....»»
Study shows effectiveness of suppressing female fruit flies
Populations of Drosophila suzukii fruit flies—so-called "spotted-wing Drosophila" that devastate soft-skinned fruit in North America, Europe and parts of South America—could be greatly suppressed with the introduction of genetically modified D. s.....»»
Stretching changes the electronic properties of graphene
The electronic properties of graphene can be specifically modified by stretching the material evenly, say researchers at the University of Basel. These results open the door to the development of new types of electronic components......»»
A way to surmount supercooling
Scientists at Osaka University, Panasonic Corporation, and Waseda University used scanning electron microscopy (SEM) and X-ray absorption spectroscopy to determine which additives induce crystallization in supercooled aqueous solutions. This work may.....»»
Attomolar sensing: Fabrication of surface-enhanced Raman scattering substrate
Surface-enhanced Raman scattering (SERS) permits multidisciplinary trace analyses and the potential detection of single molecules. Shi Bai and Koji Sugioka from RIKEN report a comprehensive review of recent progress in strategies for the fabrication.....»»
Every mainland Australian state now allows GMO crops
On July 1, the New South Wales government will lift a ban on genetically modified (GM) crops after an 18-year moratorium. It will mean GM crops can now be grown in every Australian state except Tasmania......»»
Mosquito love songs send mixed message about immunity
As mosquito-borne diseases pose risks for half the world's population, scientists have been releasing sterile or genetically modified male mosquitos in attempts to suppress populations or alter their traits to control human disease......»»
Reducing errors in X-ray photoelectron spectroscopy
X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science. Researchers at Linköping University, Sweden, however, h.....»»
A rapid test for detecting fire blight in plants
RUDN University biotechnologists have created a method for detection of bacterial infection in apple, pear, hawthorn and other plants of the Rosaceae family. The test does not require laboratory equipment, the result is ready in 10 minutes. This will.....»»
Measuring the elimination of plastic particles from the body in mice
The accumulation of micro- and nanoplastics in the environment continues at an alarming rate. A radiolabelling technique developed at the University of Helsinki made it possible to monitor the movement and accumulation of plastics in the mouse body,.....»»
