Wonder if it will catch on. A new paper, posted on the database arXiv, introduces a name for a new field of research: proteotronics, or the study and development of electronic circuits with proteins as a plug-in part.
Apparently, proteins have their own unique electrical properties. Run a current through them, and different proteins will react differently. The paper’s authors, a team of three engineers from Italy, demonstrated that one protein is even able to act as a switch, The Physics arXiv Blog reports. The researchers ran a current through a protein called OR-17, which is normally found in rats’ noses and reacts to fruity-smelling chemicals called aldehydes. The researchers found OR-17 has different electrical properties when it senses different concentrations of an aldehyde called octanal. It’s a switch that flips in response to the presence of octanal.
Where you could use a protein switch is still an open question. One obvious answer is in electronic detectors that find things like contaminants in water, pollutants in the air, or chemical signs of illness in people. Find a protein that reacts to the chemical you’re interested in, measure the protein’s electrical changes, and voilà , you’ve got a protein-based electronic detector. This could be another approach to the electronic noses researchers have developed in recent years. Protein-based devices would have one major challenge to overcome, however. They would have to find a way to keep potentially delicate proteins intact and functional inside a silicon gadget.

I used to play this old PC game called USS Ticonderoga. It was a pretty clunky modern naval simulation, but I persisted with it for one reason: it let you explore your ship in first-person. I can’t believe it’s taken this long for another game to realise how awesome that premise is.

Valve announced today that its new in-home streaming feature, which allows you to stream games from a "main" computer to any other rig in your home, is now available to all 75 million Steam users. Previously, the feature was only available to some users in beta.
One of the main benefits of Steam in-home streaming is that you can play your PC games on a lower-spec computer because they are not actually running on that rig, only being streamed to it. Video and audio are streamed from your main computer over your network.
Steam’s in-home streaming service also works across platforms, allowing you to stream from a Windows computer to a computer running OS X, Linux, or SteamOS. In the future, Valve says it will allow OS X, Linux, and SteamOS machines to host streams.
Using Steam’s new in-home streaming, you could also hook up your laptop or low-end PC to your TV and stream games to it using Steam’s Big Picture mode.
The arrival of in-home streaming comes ahead of the official release of Steam Machines and the Steam Controller later this year. You can read more about Steam in-home streaming at Valve’s website.

More than 30,000 miles of decrepit iron pipes carry explosive natural gas in the U.S. But shortages of funds, manpower and materials mean some might not be replaced until 2050.
