Electron microscopy experiments can only use a fraction of the possible information generated, because the microscope’s electron beam interacts with samples. Now, researchers have designed a new kind of electron detector that captures all of the information in these interactions. This new tool captures more images at a faster rate, revealing atomic-scale details across much larger areas than was possible before.

A research team has created a nanoscale “playground” on a chip that simulates the formation of exotic magnetic particles called monopoles. The study could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and next-generation hard drives that employ the power of magnetic spin to store data.

Scientists have developed a user-friendly approach to creating 'theranostics' -- therapy combined with diagnostics -- that target specific tumors and diseases. They have developed a novel method to prepare cell-penetrating nanoparticles called 'metallocorrole/protein nanoparticles.' The theranostics could both survive longer in the body and better snipe disease targets.

Researchers have developed a novel way to entangle two photons -- one with a wavelength suitable for quantum-computing devices and the other for fiber-optics transmissions. To create the entangled pairs, the researchers constructed a specially tailored optical "whispering gallery" -- a nano-sized silicon nitride resonator that steers light around a tiny racetrack.

Scientists at Harvard University are pursuing many novel approaches to fighting cancer, including nanoparticles attached to red blood cells that can escape detection by the body’s liver and spleen, which could pave the way for more effective, less toxic drug delivery.
