  • Citibank is working on its own digital currency called Citicoin. Citigroup is looking seriously into the new technology and has built its own digital currency based on Bitcoin and the blockchain.

  • A new company is using the power of hemp to build homes. After the devastating Hurricane Katrina wiped out entire communities, James Savage, then a Wall Street analyst living on Central Park West, started looking for a better, quicker solution to rebuild homes quickly. He started a company that derives building materials from cannabis. Hempcrete is made by combining the woody, balsa-like interior of the Cannabis sativa plant with lime and water. It provides natural insulation that is airtight yet breathable and flexible; free from toxins, mold, and pests; and virtually fireproof. — The New York Times
     
  • Ghost tech lets you pull objects out of the screenEmerge lets you pull data out of a bar chart with your fingers and move it around, while Morphees are flexible devices that can change shape automatically according to your needs, stretching to shield your fingers when you type in a pin code, for example. This revolutionary technology could be just five years away. — Tech Radar
     
  • Australian researchers have designed a zebra-striped wetsuit to scare sharks away.

  • A new study reveals the impact that violent video games actually have on your brain. Stetson University psychology professor Christopher J. Ferguson conducted three studies on 12- to 18-year-old gamers and found no correlation between shooting fake people on a computer monitor or TV screen and real-world aggression. But playing games all day isn't exactly good for you either. These sedentary activities can lead to an increase in anxiety. — Upworthy
