It used to be that 3D printers were only capable of printing plastic objects that resemble real-world objects minus the functionality. These days, however, 3D printing has revolutionized the way some functional objects are made, whether as a whole or as a part. One great example of this is Amsterdam’s metal footbridge that’s being constructed by torch-wielding robots through 3D printing.
The latest chapter of the evolution of 3D printing involves micro-organs and a new revolutionary technique that will one day allow doctors to simply print out micro-organs for transplant patients who need them. 3D-printed assemblies that are loaded with embryonic stem cells have great potential in making this life-saving concept a reality.
Light is the fastest thing in the known universe. Harnessing this power and integrating it in a piece of chip is a truly remarkable feat with potentially infinite applications. Research scientists have recently discovered a new way of harnessing the speed of light and integrating it in a microchip. Although we’re still a long way away from building starships that can travel faster than the speed of light, the technology behind this recent innovation could lead to a whole new generation of microchips that are light-based, potentially powering superfast and super smart quantum computers.
Theoretically speaking, light in a vacuum can travel at speeds of up to 1.08 billion kilometers per hour. This is the fastest possible speed at which matter, or energy, can travel according to Einstein’s theory of relativity. So, for now, time travel is still a thing of science fiction, at least until we figure out how to break the speed of light.
Almost four years after Professor Harald Haas of Edinburgh University introduced Li-Fi during a Technology, Entertainment and Design (TED) conference last 2011, the super-fast optical wireless communications system boasting of Internet speed of 1 Gbps (gigabits per second) Li-Fi is finally being tested in the real world after an Estonian startup company Velmenni started implementing the technology in offices around Tallinn.
Li-Fi, which utilizes visible spectrum in delivering data, is considered to be 100 times faster than the traditional Wi-Fi. The speed that Li-Fi offers makes downloading high-definition movies in just a few seconds a reality. Unlike Wi-Fi, which uses radio waves to send data, this new optical wireless communications technology uses a light source in delivering information.
