Scientists destroy 99% of cancer cells with groundbreaking new method
A special form of molecule has been found to "tear apart" the membranes of cancer cells once activated, a promising new study by scientists at Rice University in Texas has revealed.Known as aminocyanine molecules – and commonly used as synthetic dyes in medical imaging – their atoms can vibrate in u...

Demon Hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle
In 1956, theoretical physicists predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a 'demon.' Since then, it has been speculated to play an important role in the behaviors of a wide variety of metals. Unfortunately, the same properties that make it interesting have allowed it to elude detection since its prediction.
mc ☕> 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"
Background-free four-wave mixing microscopy of small gold nanoparticles inside a multi-cellular organ
The ability to detect small metallic nanoparticles by optical microscopy inside environmentally relevant species may have a wide impact for ecotoxicology studies. Here, we demonstrate four-wave mix...
"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."

Observation of hydrodynamic plasmons and energy waves in graphene - Nature
By using new on-chip terahertz spectroscopy techniques to measure the absorption spectra of a graphene microribbon as well as the energy waves close to charge neutrality, hydrodynamic collective excitations are observed.
