Ultrasound-activated microbubbles form high-speed jets for drug delivery

 Physics General News
 21 February 2025
ETH Zurich researchers have investigated how tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles penetrate the cell membrane, enabling the drug uptake....

What can theoretical physics teach us about knitting?

 21 February 2025
The practice of purposely looping thread to create intricate knit garments and blankets has existed for millennia. Though its precise origins have been lost to history, artifacts like a pair of wool socks from ancient Egypt suggest it dates back as early as the third to fifth century CE. Yet, for...

Magnetic 'invisibility cloak' hides obstacles within particle streams

 Physics General News
 21 February 2025
Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a particle stream. Until now, this so-called cloaking had only been studied for waves such as light or sound. They report their results in Nature Communications....

Nickel superconductor works above -233°C threshold at normal pressure

 Physics General News
 21 February 2025
A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold under ambient pressure. In their study published in Nature, the researchers synthesized thin films of...
