A strongly adhesive hemostatic hydrogel for the repair of arterial and heart bleeds | Nature Communications
UV hardening/gelling hydrogel as a way to sell wounds. Sticky so can be used to seal blood vessels. In the Vietnam War, the US military used superglue in the same capacity, but the skin irritation factor is the reason why the FDA never approved it for civilian use.

Hachimoji DNA and RNA: A genetic system with eight building blocks | Science
SBPZ are the new letters, with potential expansion to 12 total letters. Still need to build up the synthetic biology to actually build stuff from the new base pairs, but now we can code it. Maybe useful as a forensic marker for GMO as it is not natural?

Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.

How Canadian researchers reconstituted an extinct poxvirus for $100,000 using mail-order DNA | Science | AAAS
This is kinda bad, but it was known that this was going to happen eventually. The mail order DNA/protein synthesis companies do screen the orders, but small enough fragments spread out over enough companies would evade detection. Now all it takes is a reasonably well educated individual (read bioengineering grad student), and oh hey, a certain class of extremists tend to originate from engineering backgrounds due to a black/white worldview and then...

So there is apparently a cockroach that births live young, and lactates to feed them. The milk they produce has a special multilayered milk protein crystal structure that acts as a time release complete food as it's processed, with integrated proteins/lipids/sugars. If this can can be reasonably synthesized, it' s a superfood (crystals have 3 times the caloric content of buffalo milk)

Spiber Inc.
Japanese company commercializing mass production artificial spider silk via genetically modified microorganisms (bacteria?). The fibroin biopolymer based fiber will be called QMONOS and is scheduled for 2015 mass production at the pilot plant (100Kg/month). Except there is a swedish company with the same name, and had research in approximately the same time frame, and looking for partners. Yet this japanese company's site seems to artfully mention that this is a japanese technology push. Something smells fishy here...

Unexpected Strength and Toughness in Chitosan-Fibroin Laminates Inspired by Insect Cuticle - Fernandez - 2011 - Advanced Materials - Wiley Online Library
Interesting biomimicry research of beetle shell cuticles, using spider silk proteins mixed with shrimp derived chitin. This creates a thin film laminate with strength/toughness comparable to aluminum alloys but half the weight. Can be molded and the stiffness/elasticity can be controlled by changing the water content during fabrication.
