Nielsen’s new Connected Devices study is out:
- Social Media — 44% of 18-24 year olds and close to 50% of 25-34 year olds are visiting social networking sites on their smartphones during both commercials and programs while watching TV.
- Seeking Information — 36% of people 35-54 and 44% of people 55-64 use their tablets to dive deeper into the TV program they are currently watching.
So the older folks are relying on search to make their experience of TV richer, while the youths are relying on each other.
So you know, how to make invisible ink. Complement with the grown-up history of invisible ink and pre-Internet privacy hacking.

“California once again finds itself on the cutting edge of technological advances, at a legislative level. Only this time, it’s with education: Governor Jerry Brown has signed a proposal into law that allows students to download digital…
If someone told you that the shallow seabeds of Northern Europe were full of buried electrical wiring, you might say “Yeah, internet and phone and stuff. So what?” But what if that person told you that the wiring was alive?
Don’t worry. They aren’t crazy. Danish scientists have described a bacterium that can assemble itself into filaments many centimeters long (which is cool by itself), and use those filaments to conduct electrical currents! One square meter of seabed can have kilometers of bacterial cable beneath it!! So how does it work?
Decomposing materials deep in the mud are digested by all kinds of microorganisms and create “sulphide” compounds. These sulphides transfer electrons to one buried end of the bacterial chain, who then transfer it up to the water-exposed end where those electrons can be used to harvest oxygen for metabolism. Just like we do in our cells!
Only they do it via a way cooler method than we do. I really don’t know what’s more interesting, that these are multicellular bacteria (for all intents and purposes), or that they are basically living electrical wires.
Here’s the paper in Nature, if you have access.
