AI-assisted technology detects nanoplastics in water—instantly
A McGill-led research team has developed the first real-time, on-site technology capable of detecting and deciphering nanoplastics from all other particles in water, a capacity akin to being able to find a needle in a haystack within milliseconds......»»
New photonic crystal approach can enable sensitive and affordable detection of biomarkers
Biomarkers are small molecules of interest to researchers, because they can indicate underlying diseases, often even before symptoms even appear. However, detecting these markers can be challenging as they are often present in very low quantities, es.....»»
Scientists develop most sensitive method yet for observing single molecules
Scientists at the University of Wisconsin–Madison have developed the most sensitive method yet for detecting and profiling a single molecule—unlocking a new tool that holds potential for better understanding how the building blocks of matter inte.....»»
New modified CRISPR protein can fit inside virus used for gene therapy
Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells. Hongjian Wang and colleagues a.....»»
Biologists find nanoplastics in developing chicken heart
Nanoplastics can accumulate in developing hearts, according to a study published in Environment International by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a t.....»»
Detecting "Hawking radiation" from black holes using today"s telescopes
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking radiation should be obse.....»»
