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.

Practical Application Limits of Fuel Cells and Batteries for Zero Emission Vessels
Uh, they only cover batteries or liquid/gaseous hydrogen PEM fuel cells in the comparison, so kinda incomplete. So no LNG fuel cells, no fuel cell/microturbine hybrids using the microturbine combustor as a topping cycle. Also, the basic conclusion is huge vessels could run a full trip, but on liquid hydrogen only, and short trip ferries should look at batteries instead.

The Microtransat Challenge
Interesting that IMO/COLREGS treats these autonomous sailing boats as either debris, or oceanographic monitoring buoys if equipped with oceanographic sensors. US Coast Guard basically doesn't care as long as they're under 8 feet in length, though there is confusion over whether they are using a 4m or 2.4m ruling.

Kra Canal (Thailand) excavation by nuclear-powered dredges
Considering the current existence of the russian nuclear power barge, a nuclear dredger isn't wholly insane. But, considering it would be operating in foul water due to kicked up sediment, conventional sea cooling probably isn't available, limiting power generation ability. Doubt you want to use an air cooled reactor on a ship either...

OmniTHRUSTER
Basically a jet drive with a single ventral inlet and a choice of side outlet nozzles, with butterfly valves determine which ports don"t get jet power. The idea is that zero force occurs when equal jets are coming out both sides, so that you can have full side force instantaneously but cutting off one side rather than ramping up the pump for the jet.

Lloyd's and Hyperion Power Systems are teaming up to do dev work regarding modern shipping using small modular nuclear reactors as powerplants/engines/steam generators for large ships with a defined high speed need. There was some interesting work recently that a three ship fleet with nuclear power for the transpacific container cargo transport market could seriously beat a 4 ship fuel oil powered fleet on a profit and tons/day or tons/mile basis.
