Optogenetic Induction of Colonic Motility in Mice - Gastroenterology
Short version, blue LED's in the intestines relive constipation. So future laxatives might be a blue LED studded pill.

f.lux: software to make your life better
Software for red shifting computer interfaces at night to make it easier to transition to sleep. Apparently blue light tends to make us more alert (as a component of a full spectrum white light trying to emulate the sun), sun reducing the amount of blue, or the alternative being wearing blue filter sunglasses at night (which apparently is a thing and seems to also work if worn the hour before bed)

Sonardyne announces collaboration with WHOI engineers to launch a unique subsea optical communication technology – BlueComm
No company website yet, but Lumasys will be fielding commercial versions of BlueComm, a 200m range underwater blue LED optical communications platform, capable of 20Mbps. Matching this up with both TCP/IP, and delay tolerant networking (DTN) would make this really useful for underwater ROV teleoperation. Unfortunately, probably still defeated by a container full of tape in the bandwidth department, but beats the pants off acoustic systems (if you can tolerate the range limit or can employ a relay mesh network).

Single-cell biological lasers : Nature Photonics : Nature Publishing Group
Externally pumped laser using external blue light, with external micromirrors, using the cell as a lasing medium of sorts. So the next issue is producing blue light to pump the GFP, and biologically secreted mirrors, and pretty soon the laser shark meme will become real.

The Edgefighter | An open dialogue on innovation in the defense industry.
funny blog by the guys doing the system integration for the Air Force's Blue Devil surveillance airship/intelligence data server in the sky platform. Blue Devil is a conventional airship promoted by the Air Force, as opposed to LEMV, a hybrid airship being pushed by the Army that does similar persistent surveillance.

These guys will be building the blue devil surveillance blimp for use in Afghanistan, which will be a super eye in the sky, coupled with an onboard server cluster to process data in realtime, and a wireless intelligence server onboard to feed only selected data to requests from the ground and in the air, rather than pumping everything offboard via a firehose data link.
