The beat goes on with a new model for artificial flagella

(Phys.org) —Eukaryotic flagella, whip-like organelles that elegantly propel microorganisms and pump fluid, seem to embody simplicity on the microscopic scale. But appearances can be deceptive: Flagella are composed of 650 ...

Butterfly inspires new nanotechnology

By mimicking microscopic structures in the wings of a butterfly, an international research team has developed a device smaller than the width of a human hair that could make optical communication faster and more secure.

World's most powerful microscope ready for research

(Phys.org) —The world's most powerful microscope, which resides in a specially constructed room at the University of Victoria, has now been fully assembled and tested, and has a lineup of scientists and businesses eager ...

Elucidating energy shifts in optical tweezers

A small piece of paper sticks to an electrically charged plastic ruler. The principle of this simple classroom physics experiment is applied at the microscopic scale by so-called optical tweezers to get the likes of polystyrene ...

Scientists image nanoparticles in action

(Phys.org) —The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give ...

Close look at iron-based superconductor advances theory

(Phys.org)—Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported in the Feb. ...
