Looks like there is another way to use plastic bottles.

Why not use your old plastic bottles as the joining material?

Scientists have created a super white paint that is the yin to Vantablack’s yang.

While ultra black materials can today absorb more than 99.96 percent of sunlight, this new super white coat can reflect 95.5 percent of all the photons that hit it.

Instead of warming up under direct light, objects painted with this new acrylic material can remain cooler than their surrounding temperature even under the Sun, which could allow for a new energy-efficient way to control temperature inside buildings.

“Frustration” plus a pulse of laser light resulted in a stable “supercrystal” created by a team of researchers led by Penn State and Argonne National Laboratory, together with University of California, Berkeley, and two other national laboratories.

This is one of the first examples of a new state of matter with long-term stability transfigured by the energy from a sub-pico-second laser pulse. The team’s goal, supported by the Department of Energy, is to discover interesting states of matter with unusual properties that do not exist in equilibrium in nature.

Photos of touching down on an asteroid.

On Tuesday, October 20th, NASA made history when the OSIRIS-REx mission successfully completed a “touch-and-go” sample collection maneuver with asteroid 101955 Bennu over 200 million miles away from Earth. And now, we have the timelapse to prove it.

The human eye does not work like a camera, contrary to common belief. Consider the following key factors:

1) Both the cornea and the lens COMBINE to give the focusing effect. Thus it is TWO lenses, not one that allow human vision. In fact the cornea is responsible for two-thirds or more of the focusing effect. The lens compounds that focusing, projecting it from past the pupil onto the curved retina at the back of the eye.

2) The eye corrects for CHROMATIC ABERATION by having a central pit, the FOVEA, where the blue cells are concentrated along the outer rim and the red cells concentrated in the center. Blue light focusses slightly closer to an objective lens and red light slightly further. Thus the red cells are concentrated further back, at the base of the pit, so that the human eye has a natural color correction without the need for complex color corrected lenses.

New technology could deliver “clean, limitless, low-voltage power for small devices”.

The rippling thermal motion of a tiny piece of graphene has been harnessed by a special circuit that delivers low-voltage electrical energy. The system was created by researchers in US and Spain, who say that if it could be duplicated enough times on a chip, it could deliver “clean, limitless, low-voltage power for small devices”.

Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The halo also may be where matter unaccounted for since the birth of the universe may reside. Photo courtesy of Christien Nielsen/Unsplash.

ETH researchers are making chocolates shimmer in rainbow colors without the addition of colorants. They have found a way to imprint a special structure on the surface of the chocolate to create a targeted color effect.

Traditional methods for coloring chocolate have been around for a long time. But the ETH researchers are able to create the rainbow effect without artificial colorants. The effect is achieved simply through a surface imprint that produces what the scientists refer to as a structural color. The process is similar to a chameleon, whose skin surface modulates and disperses light to display specific colors.

Researchers have designed a material that can act as a superconductor in a room heated to close to 60 degrees Fahrenheit — the warmest temperature yet.
