Molecular #jackhammers’ ‘good vibrations’ eradicate #cancer cells https://news.rice.edu/news/2023/molecular-jackhammers-good-vibrations-eradicate-cancer-cells “found that the atoms of a small dye molecule used for medical imaging can vibrate in unison ⎯ forming what is known as a #plasmon ⎯ when stimulated by #NearInfrared light, causing the cell membrane of cancerous cells to rupture….the method had a 99 percent efficiency against lab cultures of human melanoma cells, and half of the mice with melanoma tumors became cancer-free after treatment.”

Bereits 1956 wurde vorhergesagt, dass in manchen Materialien masselose, elektrisch neutrale Quasiteilchen entstehen können. Das könnte die Hochtemperatur-Supraleitung erklären.

> Since Pines' Demon is predicted to play an important role in a wide range of phenomena, such as #transitions in particular kinds of #semimetals and #superconductivity , the work has important implications for material #physics .

> Usually in science, a "demon" is a hypothetical opponent for scientists and philosophers to argue against in a thought experiment, but Pines' Demon is quite different.
It's actually a type of #plasmon – a discrete unit of waves among rippling through a population of electrons . Plasmons have been described as the #quantum analogue of an #acoustic sound in a classical gas.

"After the exposure to food containing 10 nm radius gold #nanoparticles, hepatopancreas tubules were collected, and nanoparticles were imaged by four-wave mixing #microscopy with high contrast, locating them with sub-cellular resolution in the volume.. Notably, the ultrafast dynamics of the four-wave-mixing non-linearity of gold nanoparticles resonantly excited and probed at their localized surface #plasmon allows them to be distinguished from other metal deposits"

"We observe a prominent high-frequency hydrodynamic bipolar-plasmon resonance and a weaker low-frequency energy-wave resonance of the Dirac fluid in ultraclean graphene. The hydrodynamic bipolar plasmon is characterized by the antiphase oscillation of massless electrons and holes in graphene. The hydrodynamic energy wave is an electron-hole sound mode with both charge carriers oscillating in phase and moving together."
