The birth of topological spintronics

The discovery of a new material combination that could lead to a more efficient approach to computer memory and logic is the first promising indication that it may be possible to build a practical technology with a novel material known as a 'topological insulator'. The research team's results show that such a scheme can be 10 times more efficient for controlling magnetic memory or logic than any other combination of materials measured to date.

The electric slide dance of DNA knots

DNA has the nasty habit of getting tangled and forming knots. Scientists study these knots to understand their function and learn how to disentangle them. Researchers have now devised and tested a method based on the application of electric fields and optical tweezers.

Microscopy charges ahead

Polarization charges in ferroelectric materials are screened by equal amounts of surface charges with opposite polarity under ambient conditions. Researchers have shown that scraping, collecting, and quantifying surface screen charges reveals the underlying polarization domain structure at high speed, a technique dubbed charge gradient microscopy (CGM).
