Standard method to evaluate emerging flat lens technologies

Perhaps you are wearing glasses while reading this or have a cell phone, binoculars, a virtual reality headset or telescope. All of them rely on high-quality lenses, which are bulky, expensive and heavy—especially when ...

Cellular tornadoes sculpt organs

How are the different shapes of our organs and tissues generated? To answer this question, a team from the University of Geneva (UNIGE), Switzerland, forced muscle cells to spontaneously reproduce simple shapes in vitro. ...

The tiny structures that mimic a cell's natural environment

When biologists study cells under a microscope, they look at them on flat surfaces that are nothing like the environment inside the human body. Now, researchers at NTNU have found a way to mimic some aspects of a cell's native ...

Watch how cells squeeze through channels

Observations of cells moving through small channels shed new light on cell migration in 3-D environments, researchers report October 6 in Biophysical Journal. The findings also reveal how cancer cells may penetrate tissues ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Puzzling shapes: Unlocking the mysteries of plant cell morphology

The discovery of the mechanics and molecular mechanism that dictate cell shape formation in plants by a team of McGill researchers offers new clues about the fundamental processes governing tissue formation in multicellular ...

All-in-one transparent transistors

Small tweaks in component ratios generate electronically different layers from the same material to create transparent transistors.

Why Elon Musk is wrong about nanotechnology

You might expect Elon Musk, the business magnate, engineer and serial entrepreneur would be a fan of all things techy. After all, his radical enterprises are built on pushing science to its limit. He's behind a raft of visionary ...
