One of the key innovations of the new 3-D-printing technique on skin is that the printer uses computer vision to track and adjust to movements in real-time. Credit: McAlpine group, University of Minnesota

Groundbreaking technology could help soldiers on the battlefield and people with skin disorders. In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.

How researchers are using lasers to recreate the extreme pressures of exoplanet interiors. Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. Scientists have identified more than 2,000 of these “super-Earths,” exoplanets that are larger than Earth but smaller than Neptune, the next-largest planet in our solar system...

A dense flock of 14 galaxies from 1.4 billion years after the Big Bang is destined to become one of the most massive structures in the modern universe. For the 1st time, astronomers have witnessed the birth of a colossal cluster of galaxies. Their observations reveal at least 14 galaxies packed into an area only 4 times the diameter of the Milky Way’s galactic disk. Computer simulations of the galaxies predict that over time the cluster will assemble into one of the most massive structures in the modern universe, the astronomers report in the April 26 issue of Nature.

A: Food materials are pulverized under ultra-low temperature close to -100 degrees Celsius. B: Micro-sized food materials are reconstructed into a porous film-shaped material by jetting bonding an agent under optimized water content and heat conditions. The process to build film-type materials is repeated layer by layer to form to a three-dimensional food block. C: The exterior of foods and internal microstructure of a food block with specific porosity is designed to give texture with controlled human body absorption while eating and ingesting.
