3-D sketching with air scaffolding

People often use their hands when describing an object, while pens are great tools for describing objects in detail. Taking this idea, a KAIST team introduced a new 3-D sketching workflow, combining the strengths of hand ...

Team creates high-fidelity images of Sun's atmosphere

In 1610, Galileo redesigned the telescope and discovered Jupiter's four largest moons. Nearly 400 years later, NASA's Hubble Space Telescope used its powerful optics to look deep into space—enabling scientists to pin down ...

Slow motion playback makes football referees harsher

Football referees penalize situations more severely when watching them in slow motion compared to real time, according to a study published in the open access journal of the Psychonomic Society, Cognitive Research: Principles ...

New tools reveal prelude to chaos

Picture a herd of sheep or cattle emerging from a shed or barn to graze a field. They head straight out of their digs to the pleasure of the pasture pretty much as one entity, but as the land opens up and the "grass gets ...

Supersonic waves may help electronics beat the heat

Researchers at the Department of Energy's Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice—a discovery ...

Wiggling atoms switch the electric polarization of crystals

Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale that originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is ...

IBM scientists demo rocking Brownian motors for nanoparticles

Today, our IBM Research team published the first real world demonstration of a rocking Brownian motor for nanoparticles in the peer-review journal Science. The motors propel nanoscale particles along predefined racetracks ...
