Phys.org / Female meiosis in plants can be directly observed with new method

A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis thaliana. The FeM-ID ...

Phys.org / Chemistry-powered 'breathing' membrane opens and closes tiny pores on its own

Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales. The narrowest regions ...

Tech Xplore / What does 'flexibility' actually look like? New findings suggest speed limits for wearable devices

Flexible electronics are often sold on a simple promise: bendable screens, lightweight solar cells or wearable devices that can bend and flex without breaking. But what does that "flexibility" actually look like at the molecular ...

Phys.org / World's smallest QR code, read via electron microscope, earns Guinness recognition

Just how small can a QR code be? Small enough that it can only be recognized with an electron microscope. A research team at TU Wien, working together with the data storage technology company Cerabyte, has now demonstrated ...
