Nov 02, 2022 (Nanowerk News) A team of Canadian researchers from Université de Montréal has designed and validated a new class of drug transporters made of DNA that are 20,000 times smaller than a human hair and that could improve how cancers and other diseases are treated. Reported in a...
Living bioelectronic sensors made with programmable bacteria sense and report contaminants
Nov 02, 2022 (Nanowerk News) When you hit your finger with a hammer, you feel the pain immediately. And you react immediately. But what if the pain comes 20 minutes after the hit? By then, the injury might be harder to heal. Scientists and engineers at Rice University say the...
Physicists shed new light on unanswered questions about glass-liquid transition
Nov 02, 2022 (Nanowerk News) Glasses are peculiar materials exhibiting excellent and well-known properties, but also some phenomena that are still not fully understood, even though they have been studied for more than a century. In particular, researchers have not yet reached a complete description of the glass formation process,...
Delivering genes into plant mitochondria using polymer-coated carbon nanotubes
Nov 02, 2022 (Nanowerk News) RIKEN biologists have found an effective way to smuggle genetic material into the energy generators of plant cells, opening up the possibility of coaxing plants to produce commercially useful compounds (Nature Communications, "Polymer-coated carbon nanotube hybrids with functional peptides for gene delivery into plant mitochondria")....
Webb reveals the oldest star clusters in the universe
Nov 02, 2022 (Nanowerk News) A team of Canadian astronomers, including experts from the Dunlap Institute for Astronomy & Astrophysics in the University of Toronto's Faculty of Arts & Science, have used the James Webb Telescope (JWST) to identify the most distant globular clusters ever discovered – dense groups of...
Quantum dots form ordered material
Nov 01, 2022 (Nanowerk News) Quantum dots are clusters of some 1,000 atoms which act as one large ‘super-atom’. It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, a large number of dots have to be combined...
A new control system for synthetic genes
Nov 01, 2022 (Nanowerk News) Using an approach based on CRISPR proteins, MIT researchers have developed a new way to precisely control the amount of a particular protein that is produced in mammalian cells. This technique could be used to finely tune the production of useful proteins, such as the...
