Space and security are the topics this week; from star wars cruises to space submarines and huge password dumps to counter reverse-engineering software.

Now that NASA has got the hang of planetary rovers, the space agency is looking at sending submarines into space around the year 2040. At the recent 2015 NASA Institute for Advanced Concepts (NIAC) Symposium in Cocoa Beach, Florida, NASA scientists and engineers presented a study of the Titan Submarine Phase I Conceptual Design, which outlines a possible mission to Saturn’s largest moon, Titan, where the unmanned submersible would explore the seas of liquid hydrocarbons at the Titanian poles.
Thefts involving smartphones have declined dramatically in three major cities since manufacturers began implementing “kill switches” that allow the phones to be turned off remotely if they are stolen, authorities said on Tuesday.
According to an article in Des Moines Register, the agency is in the early stages of developing mobile
Thync today announced results from a study published via bioRxiv that show electrical neurosignaling delivered by its consumer wearable device reduces the brain’s response to stress in a chemical-free manner.
On earth we only have two energy sources: the Sunshine and thermonuclear1.
Sunshine actually produces all of these:
We have an impressive electric grid that delivers a lot of this to our homes and runs our lives, and electricity is an amazingly useful transportation mechanism, but sometimes it is nice to have non-plugged in sources of power. (Batteries only go so far)
People have spoken a lot about Hydrogen as a fuel. And we can make hydrogen from Electricity, though this is not traditionally very efficient. Also, though compressed Hydrogen has a great energy density (142 MJ/kg) it has some challenges. Additionally we have a lot of technical experience and infrastructure based on combustion. Gasoline (44.4 MJ/kg) is widely used.
Being able to create a combustable fuel from sunlight directly would be great. As we wouldn’t have an electrical middle step which incurs loss.

Their work integrates an “artificial leaf,” which uses a catalyst to make sunlight split water into hydrogen and oxygen, with a bacterium engineered to convert carbon dioxide plus hydrogen into the liquid fuel isopropanol.
1 There are other energy sources available on Earth: geothermic and gravitational sources (hi moon), but we mostly harness thermonuclear, and Sunlight and it’s side effects.
Going forward, unless a phone is connected in some way to an account that owes the carrier money, said carrier will unlock the phone if asked to do so.
At the SyScan conference next month in Singapore, security researcher Jacob Torrey plans to present a new scheme he calls Hardened Anti-Reverse Engineering System, or HARES. Torrey
