Lab grown skin

Yes, it’s for real. The Indian institute of technology has been able to print for the first time 3D skin. The model has been made using a 3 D printer and it mimics the exact structure and function of the human skin. This could…

Liquid 3 D printing

“Rapid Liquid Printing” uses gel to suspend its creations. MIT collaborated with furniture firm Steelcase to create it. Rapid Liquid Printing physically draws in 3D space within a gel suspension, and enables the creation of large scale, customized products made of real-world materials. Compared…

Physicists create Star Wars-style 3D projections — just don’t call them holograms

They may not technically be holograms, but they’re pretty impressive: Researchers have created moving 3D images that are viewable from any angle. The technique, called volumetric display, comes from the lab of Daniel Smalley at Brigham Young University. Smalley’s team uses two sets of…

Volumes

“Volumes” is an experimental art film by Maxim Zhestkov using physics-based particle animation. Waves and unseen forces send billions of color-changing particles aloft in the film. The motions – especially the way the particles seem to tear themselves – are reminiscent of a complex…

Positron

August 2 is reserved to the positron On this day in 1932, Caltech physicist Carl Anderson discovered the positron, the first particle of antimatter to be identified. Anderson had not set out to hunt antimatter. He had built a cloud chamber to determine the…

Pavo

In the image, taken by the Hubble Space Telescope and processed by Judy Schmidt (https://twitter.com/SpaceGeck), you can see the sparkly irregular galaxy IC 4710 in the constellation of Pavo (The Peacock, https://goo.gl/6GQKNp), about 34 million light-years away from Earth. The image is also showing…
