3D printing has come a long way since the first “rapid prototyping” patent was rejected in 1980. Still, there’s a big issue: once objects are printed, they’re final. But imagine if, for example, you could recolor your iPhone case or earrings to match whatever outfit you’re wearing. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have gotten closer to making that a reality. In a new paper, they present “ColorFab,” a method for repeatedly changing the colors of 3D printed objects after fabrication.

Using their own 3D printable ink that changes color when exposed to UV light, the team can recolor a multi-colored object in just over 20 minutes – and they say they...

Nanoscale chiral valley-photon interface through optical spin-orbit coupling. Researchers from TU Delft combine spintronics and nanophotonics in 2D material Delft University of Technology

Spintronics is an emerging field in which the spin of electrons, rather than the charge, is used to process data. Unfortunately, the spin only lasts for a very short time, making it difficult to exploit in electronics. Researchers from the Kavli Institute of Nanoscience at TU Delft, working with the Netherlands Organisation for Scientific Research’s AMOLF institute, have now found a way to convert spin information into a predictable light signal at room temperature...

A team has succeeded in developing world’s first stretchable aqueous Li-ion batteries that may power the next generation of wearable devices. A recent study, affiliated with UNIST has presented a bioinspired Jabuticaba-like hybrid carbon/polymer (HCP) composite that was developed into a stretchable current collector using a simple and cost-effective solution process. Using the HCP composite as a stretchable current collector, the research team has, for the first time, developed a highly stretchable rechargeable lithium-ion battery (ARLB) based on aqueous electrolytes.

Stretchable electronic devices have recently attracted tremendous attention as next-generation devices due to their immense flexibility...

Blue Waters numerical relativity simulation of two colliding black holes with the open source, numerical relativity software, the Einstein Toolkit. Authors: R. Haas and E. Huerta (NCSA/University of Illinois); Visualization: R. Haas.

Scientists at the National Center for Supercomputing Applications (NCSA), at the University of Illinois at Urbana-Champaign, have pioneered the use of GPU-accelerated deep learning for rapid detection and characterization of gravitational waves. This new approach will enable astronomers to study gravitational waves using minimal computational resources, reducing time to discovery and increasing the scientific reach of gravitational wave astrophysics. This innovative research was recently published in Physics Letters B.
