— It's made of what are known as supramolecular polymers, which have reversible bonds that function like sticky notes that can be attached, removed and reattached, according to the team.
— Scientists at the Ulsan National Institute of Science & Technology (UNIST) in South Korea have unveiled a novel diagnostic technique known as fluorescence in situ hybridization (FISH), using artificial polymers — peptide nucleic acid (PNA) — that act as probes to bind to different genetic sequences within bacteria. When the two probe molecules bind to the target, fluorescent signals are emitted, which essentially reveal the fingerprint of different pathogens.
— In the lab, FISH detected seven species of bacteria that commonly infect humans — Klebsiella pneumoniae, Proteus mirabilis, Bacillus subtilis, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus. It proved to be more than 99% accurate for all but S. aureus — a pathogen that infects skin tissue — which had a still-high success rate of 96.3%. Some detections were as high as 99.9%.
— Unlike Geneva's LHC, which uses more than 9,000 superconducting magnets to accelerate particles to nearly the speed of light, the NEA relies on laser beams to excite the tiny pillars inside its structure. While this method is far less powerful, it is significantly more compact and energy-efficient.
— The primary goal of developing miniaturized accelerators is not just high-energy physics but also practical applications in medicine. The high-energy electrons generated by the NEA could be used in precise radiotherapy techniques, potentially reducing the harmful side effects associated with conventional radiation treatments.
