Explaining a supernova's 'string of pearls'      (via sciencedaily.com)     Original source 

Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research suggests. It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A.

Spiral wrappers switch nanotubes from conductors to semiconductors and back      (via sciencedaily.com)     Original source 

By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.

GPS nanoparticle platform precisely delivers therapeutic payload to cancer cells      (via sciencedaily.com)     Original source 

A newly developed 'GPS nanoparticle' injected intravenously can home in on cancer cells to deliver a genetic punch to the protein implicated in tumor growth and spread, according to researchers. They tested their approach in human cell lines and in mice to effectively knock down a cancer-causing gene, reporting that the technique may potentially offer a more precise and effective treatment for notoriously hard-to-treat basal-like breast cancers.

Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists      (via sciencedaily.com)     Original source 

When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.

Combined microscopy technique catches light-driven polymers in the act      (via sciencedaily.com)     Original source 

Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.

Discovery tests theory on cooling of white dwarf stars      (via sciencedaily.com)     Original source 

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
