Believe it or not, scientists aren't yet finished discovering new ways to 3D print body parts. A team at the Feinstein Institute for Medical Research has developed a 3D printing technique that lets them produce cartilage for repairing damaged tracheas, better known to you and I as windpipes.
IBM quit making PCs in 2005, and it quit making servers last year. But it looks like Big Blue will keep pumping out its mainframes forever.
Researchers at Northwestern University and the University of Illinois at Urbana-Champaign have developed a simple new fabrication technique to create beautiful, complex 3D micro- and nanostructures with advantages over 3D printing for a variety of uses.
The 3-D printer being used by astronauts on the International Space Station recently reached its second big milestone—it was employed to print a usable tool after a data file was uploaded from Earth that gave the printer the specifications and directions for how to produce the tool.
2014 brought more attention to 4K and curved displays than on 3D and active glasses. Toshiba launched a 4K laptop in April, LG sells a 4K curved TV, and recently Samsung introduced a 4K curved PC monitor. Apple took it a step further and released a 5K iMac refresh, followed by Dell with a 5K "smart desk", and Samsung promised to release a phone with a foldable display in 2015. Toshiba is also following the 'retina' trend and is looking to bring smooth 8K broadcasts by 2020.
