Someone could trigger these UAVs to emerge from the ocean depths from thousands of miles away.

Excellent read about future Commerce in Space — could we see an Amazon or a HomeDepot in space?
In space there are no service stations to pull into and get replacement parts for your satellite. Nor is there a towing service if a satellite is in the wrong orbit, a construction contractor to help you build structures, or a “Space Depot” for those who wish to “do-it-themselves” on orbit. In other words, we still operate within a first-generation space industrial enterprise, i.e. all commerce is on Earth, and we only focus on bits (data) coming from monolithic things that go up (i.e., satellites), which eventually die or just come down with no chance of repair or reuse.
Today the commercial space industry focuses exclusively on applications that support launching science, exploration, military, or established earth-bound data communication or delivery services, focusing data to/from space. The lack of technology to support or “markets” to enter has resulted in nebulous, unconsolidated and without-a-critical-mass investment in space-based infrastructure, industrialization, space resources (survey and process maturation) and global utility creation and delivery applications in space. However, all that may finally be changing.
Space applications that are not solely data driven are becoming real. Asteroid mining, fuel depots and commercial space stations are all being actively pursued by companies around the world, as examples of different types of revenue-generating endeavors outside of data-driven end use. These missions and their spacecraft will require greater upkeep, maintenance, repair, and consumable restoration. Consequently, “services” are now being talked about and pursued, executed from one space platform to another. The most talked-about “service” event is providing either consumables (fuel) or failure remediation to satellites on orbit, referred to as “servicing”. However, a handful of companies are seeking to break the shackles that today’s satellites are stuck with at launch, and go well beyond “servicing” into modifying and even constructing new space platforms, on orbit.
Coming clean on the story around the XS-1 Spaceplane. Hmmm; US Government coming clean; really?
ORLANDO, Fla. – Here’s a phrase that’s not repeated everyday in the space community:
“You’ve heard Elon’s comments … we want to go beyond that,” Brad Tousley, the head of the tactical technology office at the Defense Advanced Research Projects Agency, said May 15.
Elon, of course, is Elon Musk, the optimistic, and some say visionary, founder of SpaceX with plans of eventually colonizing Mars. After landing three first-stage rockets, Musk has said SpaceX would inspect the rockets with plans to later re-fly most of them. [DARPA’s XS-1 Military Space Plane Concept in Pictures].
A new form of light which makes fiber optics more secure. Los Alamos has been key player in this space due to their work on the Quantum Internet.
In a breakthrough that has the potential to alter our understanding of the fundamental nature of light, scientists from the Trinity College Dublin School of Physics and the CRANN Institute in Ireland have discovered a never before seen new form of luminescence.
Lead author Paul Eastham attests to how exciting this finding is, saying in a statement that this very fundamental property of light that has always been thought to be constant can, in fact, change.
One of the measurable characteristics of a beam of light is known as angular momentum.
A new form of light has been discovered by physicists from Trinity College Dublin’s School of Physics and the CRANN Institute, Trinity College, which will impact our understanding of the fundamental nature of light.
One of the measurable characteristics of a beam of light is known as angular momentum, The Spectrum reports. Until now, it was thought that in all forms of light the angular momentum would be a multiple of Planck’s constant (the physical constant that sets the scale of quantum effects).
Now, recent PhD graduate Kyle Ballantine and Professor Paul Eastham, both from Trinity College Dublin’s School of Physics, along with Professor John Donegan from CRANN, have demonstrated a new form of light where the angular momentum of each photon (a particle of visible light) takes only half of this value. This difference, though small, is profound. These results were recently published in the online journal Science Advances.

EU betting big on Quantum Technology.
The European Union (EU) aims to embark on an ambitious common strategy on quantum technologies, European Commissioner for digital economy and society Gunther Oettinger said here Tuesday.
At a conference which brought together some of the world’s leading experts in the field of quantum technology, European scientists and entrepreneurs launched a “Quantum Manifesto” laying out future priorities and activities to create a new “knowledge-based industrial ecosystem” in Europe.
“We aim to launch an ambitious large-scale flagship initiative to unlock the full potential of quantum technologies, accelerate their development, and bring commercial products to public and private users,” Oettinger told the conference.

For the first time, scientists at IBM Research have demonstrated reliably storing 3 bits of data per cell using a relatively new memory technology known as phase-change memory (PCM).
The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry’s attention as a potential universal memory technology based on its combination of read/write speed, endurance, non-volatility and density. For example, PCM doesn’t lose data when powered off, unlike DRAM, and the technology can endure at least 10 million write cycles, compared to an average flash USB stick, which tops out at 3,000 write cycles.
This research breakthrough provides fast and easy storage to capture the exponential growth of data from mobile devices and the Internet of Things.

The Collider That Could Save Physics
Posted in physics
Whether these Universes are similar or different to our own, whether they have the same physical laws and properties, whether they have the same fundamental constants, particles and interactions, we do not know.
And at the same time, our very best laws of nature tell us that this is reality: we are a tiny fraction of our observable Universe, which is a tiny bit of the unobservable Universe, which is just one of a tremendous number of Universes in a multiverse that’s constantly generating new ones, and has been for billions of years. And that’s the Multiverse we live in, to the best of our knowledge!
