This Week in Tech

Robots, 3D Printing and DNA

DNA storage, anyone?

The quest for smaller, larger capacity, low power storage is pretty much never ending. This week news emerged of people finally being able to store data on DNA with 100% accuracy (Motherboard, Engadget). A great long term future trend to mention to the class, though it will probably take 10 - 20 years before this becomes a commercial product. Although capacity is huge (you can fit over 2 TB of data on 1 gram of DNA!) it can take forever to do so - the researchers took 7 hours to write 2 MB of data. Then another 7 hours to read the data.

3D Printing in the spotlight

More for your current and future trends session. 3D printing is continually advancing. Almost every week there is an article on how surgeons succeed with particularly difficult operations because they first use a MRI / CAT scan to generate a 3D image of the persons body and then 3D print the part they will work on - so that they can practice the operation before surgery starts.

South Africa is not being left behind in the 3D printing revolution. The CSIR is about to go operational with the worlds largest 3D printer - capable of printing metal parts 200m long, 6m wide and 6m high. Read about the Aeroswift printer here at 3DPrint.com.

The world has its first printed on site house (Digital Trends) - and it only took 24 hours to print the house. Watch the video (a bit of a sales pitch for Apis Corp, the makers of the printer, but still an interesting watch). Another great current and future trends topic for your classes. 3D printing houses - reduced costs for making the house, huge loss of jobs for construction workers. Which is more important?

The robot revolution

From house printing robots to small, furry pollinators. Check out how a Japanese scientist is trying out a concept of using micro drones to do a bees work (because, scarily enough, bee populations are dying out around the world).

Advances in robotics continue apace, and as always, Boston Robotics is at the forefront. This week they unveiled a new machine called Handle - check out the video below to see what it can do.

For more insight into robots, their place in the workplace and people's relationships with robots there is a long but very interesting read at The New York Times. Good material for you to gain insight into robotics in the real world.

General news:

  • Gmail to allow users to receive 50MB attachments.
  • Get started with your own Ransomware kit - seriously, a maker of ransomware has a 5 minute ad for people wanting to start a life of cyber crime! Watch it at Boing Boing.
  • Body cams are cameras worn on the body of police - a rising trend in the USA. The idea is that the body cam protects both the police and the public by recording interactions - so that the police are less likely to use excessive force and so that the police can justify their actions when they do have to use force. Problem is, due to limits in battery and storage these cameras are not always on.Read about new holster technology that will activate all body cameras in the area when someone removes a gun from the holster.
  • Someone has created a braille smartwatch for the blind. Check it out here.
  • Be careful what you type - computers always take you literally. This week many internet services went offline - because they used Amazon web service and someone typed the wrong instructions into a maintenance command. Read it at Engadget.

That's it for this week. Enjoy!
