Dreaming big isn’t something Jeff Bezos has a problem with.

And true to form, the multi-billionaire’s vision for the world that his great-grandchildren’s great-grandchildren will live in is pretty wild to imagine.

The Amazon and Blue Origin boss says a trillion people will live in space, there will be “a thousand Einsteins and a thousand Mozarts” and we’ll develop other planets, leaving Earth a beautiful place to be.

Some New Yorkers who completed their vaccine series should receive a single lifetime booster shot, health officials said. These individuals include people who might have contact with someone infected or thought to be infected with poliovirus or members of the infected person’s household.

Health care workers should also get a booster if they work in areas where poliovirus has been detected and they might handle specimens or treat patients who may have polio. People who might be exposed to wastewater due to their job should also consider getting a booster, health officials said.

All children should receive four doses of the polio vaccine. The first dose is administered between 6 weeks and 2 months of age, the second dose is given at 4 months, the third at 6 months to 18 months, and the fourth dose at 4 to 6 years old.

Many of us are all too familiar with how strain in work relationships can impact performance, but new research shows that materials in electricity-producing fuel cells may be sensitive to strain on an entirely different level.

Researchers from Kyushu University report that strain caused by just a 2% reduction in the distance between atoms when deposited on a surface leads to a whopping 99.999% decrease in the speed at which the materials conduct , greatly reducing the performance of solid oxide cells.

Developing methods to reduce this strain will help bring high-performance fuel cells for clean energy production to a wider number of households in the future.

A household microwave oven modified by a Cornell engineering professor is helping to cook up the next generation of cellphones, computers and other electronics after the invention was shown to overcome a major challenge faced by the semiconductor industry.

The research is detailed in a paper published in Applied Physics Letters. The lead author is James Hwang, a research professor in the department of materials science and engineering.

As microchips continue to shrink, silicon must be doped, or mixed, with higher concentrations of phosphorus to produce the desired current. Semiconductor manufacturers are now approaching a critical limit in which heating the highly doped materials using traditional methods no longer produces consistently functional semiconductors.

Black holes are astronomical objects with extremely strong gravitational pulls from which not even light can escape. While the idea of bodies that would trap light has been around since the 18th century, the first direct observation of black holes took place in 2015.

Since then, physicists have conducted countless theoretical and experimental studies aimed at better understanding these fascinating cosmological objects. This had led to many discoveries and theories about the unique characteristics, properties, and dynamics of .

Researchers at Ludwig-Maximilians-Universität and Max-Planck-Institut für Physik have recently carried out a theoretical study exploring the possible existence of vortices in black holes. Their paper, published in Physical Review Letters, shows that black holes should theoretically be able to admit structures.

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.
