Hop "luggage that follows you"

Hop suitcase follows you around like a loyal dog

 more details

 

The Hop is a luggage bag that follows your blue tooth signal from your phone. It uses three receivers that triangulate the signals location. A micro-controller does calculations to keep the bag close. The Hop has a security function that locks itself when lost and a vibration on the phone that will alert you. Hop uses a two-track caterpillar system with compressed air to move.  This probably won't work with stairs though. The project is currently at a prototype stage but hopefully soon this thoughtful creation will be done. This bag may annoy but also help the TSA. I think this is a terrific creation because its a bag that follows you like a robot, which I think is very cool.     link to video   

Manmade Gold

                       Researchers create 24k gold in the lab

 Researchers created a 24K gold nugget by feeding large concentrations of toxic gold chloride (also known as liquid gold) to the bacteria Cupriavidus metallidurans. By doing this they made a worthless thing into a very expensive metal. To do this is very expensive in materials and takes about a week to successfully make this. People were said to remark this as reverse engineering natural processes. A portable laboratory made of 24-karat gold-plated hardware, a glass bioreactor, and the Trumpian bacteria stands on display at the Prix Ars Electronica cyber art competition in Austria until October 7.
This is a cross between microbiology and alchemy and the experiment is currently taking place at Michigan State University. I believe this could impact the prices of gold but I don't know how much since the materials do cost a lot more than the gold being made.
