Liquid crystals are used extensively in flat panel displays, where the light or dark state of each pixel is determined by the orientations of the liquid crystal molecules. Researchers are always looking for new liquid crystal phenomena to exploit, and now a team shows in a series of videos that they can generate traveling waves associated with the rotation of liquid crystal molecules [1]. The experiments demonstrate 3D control over the molecules’ orientations using an applied electric field in only one direction, a level of control that could be useful in future devices.

Jang-Kun Song of Sungkyunkwan University, South Korea, and his colleagues placed a commercial liquid crystal used for displays into the 3.5-micrometer gap between a pair of horizontal glass plates. The team also placed polarizers above and below the plates and oriented the polarizer axes at right angles. This arrangement is opaque when the rod-shaped liquid crystal molecules are oriented vertically or parallel to one of the polarizer axes but transmits light when they are in any other orientation.

The team illuminated the plates from below and filmed the liquid crystal’s response to a voltage applied across the gap. They found that particular repeating voltage patterns—for example, a square wave oscillating between +6 V and −6 V for 10 milliseconds followed by 20 milliseconds with no applied voltage—resulted in light-dark waves moving across the liquid crystal. The researchers varied the parameters for the voltage signal and measured the effects on the wave speed and direction.

The smallest distance in the universe is the unimaginably small Planck length. In this video we will try to imagine it, and explain why it is so significant.

Longtermism is influencing billionaire philanthropy and shaping politics. Should it guide the future of humanity?

Jojo Punnackal from Ernakulam, Kerala has been growing the gac fruit — an exotic and nutritious fruit from Vietnam — for the past four years. He earns around Rs 2 lakh by selling its seeds alone.

Super rich “preppers” are getting ready to survive the apocalypse in fancy, well-equipped bunkers specifically designed for that purpose.

Toxic birds and frogs have evolved a way to avoid harm—but not in the way we thought.

On August 12, the hybrid magnet of the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, generated the world’s highest steady magnetic field by a working magnet measuring 45.22 teslas (T). In comparison, Earth’s magnetic field at 0° latitude and 0° longitude only has a strength of 0.000032 teslas.

It surpassed the 45-tesla prior world record set by a hybrid magnet in 1999 at the National High Magnetic Field Laboratory of the United States.
