10 revolutionary technologies of 2016

science-1

Last post of the year and it would not be any fun if I didn’t do a roundup of mind blowing discoveries of 2016. These are things that provided solutions to big problems or opened doors for future research. In no particular order but with a bit of bias…

  1. Precise gene editing – If you haven’t picked up anything on science past few years then let it be CRISPR (pronounced crisper). CRISPR involves targeted gene modification at very specific points of chromosomes by crafted molecules.         Besides medical interventions, it could be used to increase food security by increasing crop yield and disease resistance. It also does not fall under GMO regulation as foreign DNA is not detectable in products.

Pack a printer on your next trip

If you do not identify with minimalist packing like yours truly, then airport luggage checks sit at the very top of your nightmare list. With a few hundred dollars, you can acquire your own 3-D printer and print your own clothes as fashion designer Danit Peleg does. If you have an extra nerdy friend, you may gift them a 3-D tie from 3dtie.com.

At its most basic, 3D printing is exactly as stated – creating a 3-dimensional object from a digital file. Unlike your usual ink jet that produces a single paper, these printers create objects by successively laying down several layers. A virtual model is first created using the modelling programs available or a 3D scanner if you are copying an existing object. Therefore, the possibility of using your smart phone as a 3D scanner in the future can’t be nullified. The modelling software ‘wedges’ the model into horizontal layers that the 3D printer reads and uses to seamlessly create the final object. So instead of ink, we have any of the other possible materials being dispersed from the nozzles onto a platform. There are several methods used to fuse the material together.
