Using a silicon chip coated in nanoantennas, they effectively made a metamaterial mirror for a laser, allowing a 1D laser scanner LIDAR that is solid state. Made using methods similar to LCD manufacturing, which means the beam can be actively scanned at will, so not a fixed scanning cycle either.

Smart Traveler Enrollment Program STEP
Basic safety step, logging travel plans with the state department, if you feel at possible risk for abduction. More generally, if there's a major accident/incident, and state knows you were in the area, they might check on it, and possible check in on you to see if you are okay. They also send updates to you if things start going bad in your general area.

Fully Integrated Hybrid Silicon Two Dimensional Beam Scanner | Bowers
The underlying tech behind Strobe Inc.'s (now GM/Cruise) fancy pants chip LIDAR. Uses optical phased array for one dimensional scanning, and frequency variation through a prism lens to achieve scanning in the other dimension, rather than a full 2D optical phased array (so easier to make?)

Decrease in Nitrate Concentration in Leafy Vegetables Under a Solid-state Illuminator -- Samuoliene et al. 44 (7): 1857 -- HortScience
Interesting research that giving a plant during 10% of it's total light exposure time exposure to a LED light source reduced nitrates, boosted carbohydrates, and appears to have other benefits. 10% exposure means it isn't necessary to build expensive LED lighting for all greenhouse plants (simply rotate their trays through a properly equipped area). This may be applicable to hydroponics.

Diode Pumped Alkali Lasers Could Eventually Enable Practical Airplane Based Laser Anti-Missile Systems
I can faintly hear the "Duh, why didn't I think of that!" resonating amongst a mass of laser scientists. Using a hybrid approach can achieve some goals, but I wonder in terms of overall cost of ownership and applied MJ/$ if this is really better than solid state only lasers. Especially with some of the fiber laser stuff that's been happening.
