Interesting point. But really it seems to me you're saying the slaves are the logistical support, not the fighting arm.
 
We already have robots doing logistical support.

Slaves were not the logistical support but the cornerstone of their entire economy.
States like ancient Rome/Sparta or more recently southern US states pre-civil war have become utterly dependent on slave labor and were unable to let it go.

And to get back on topic:

Fracking apparently causes earthquakes.

I don't care. Britain recently found out we have a squintilion tonnes of gas under us. It's in the hard to break rock but the upside is it's more stable.

 

Yay! Energy security!

Until the eco-freaks start screaming about an endangered wort living above the gas deposit and use the courts to render access to said deposit fiscally marginal because of all of the safeguards and regulatory excrement, Walsingham. Don't doubt me on this. Some people just seem to hate prosperity.

BBC News - Nasa tests 3D-printed rocket engine fuel injector



Nasa has announced it has successfully tested a 3D-printed rocket engine part.

The US space agency said that the injector component could be made more quickly and cheaply using the technique.

The part is used to deliver liquid oxygen and hydrogen gas to an engine's combustion chamber.

The news follows General Electric's revelation that it planned to use 3D printing technology to make fuel nozzles for its jet engines.

Nasa said that California-based Aerojet Rocketdyne had made the injector using a method called selective laser melting (SLM).

The technique involves turning a computer-designed object into a real-world part by controlling a high-powered laser beam which melts and fuses thin layers of metallic powders into the preordained shape.

The test part was smaller than would be used in a full-size rocket, but large enough to test it could withstand the heat and pressure involved.

Nasa said the component would normally have taken a year to make because of the exact measurements involved, but by using SLM the manufacturing time was cut to less than four months and the price reduced by more than 70%.

"Nasa recognises that on Earth and potentially in space, additive manufacturing can be game-changing for new mission opportunities, significantly reducing production time and cost by 'printing' tools, engine parts or even entire spacecraft," said Michael Gazarik, Nasa's associate administrator for space technology.

SLM is not the only unusual manufacturing technique being explored by Nasa.

The agency has also asked researchers at Washington State University to see whether it would be possible to 3D-print objects out of powder made from lunar rocks.

It is also testing a process called electron beam freeform fabrication (EBF3) which uses a computer-controlled electron beam gun placed in a vacuum that welds metal wires into complex shapes and patterns.

It has suggested the process could be used by astronauts to make spare parts in space.

Marijuana May Make Us Thinner, Even with the Munchies

 

 

It sounds counter-intuitive, but marijuana may help people be thinner. The illegal drug known for causing the munchies was at the heart of a recent study (published in May's Journal of American Medicine) that examined its effect on metabolic processes. The results, though certainly not conclusive, show a correlation between smaller waist circumference and marijuana use. Not only were users thinner, but they also appeared to be healthier overall than those who have never used marijuana.

Up next Marijuana cures cancer and ED.
They are seriously making it sound like it's a wonder drug even when the evidence its indiscernible.
Although marijuana helping stay thin may be why Shaggy was so skinny even though he ate like a horse.

Giant Virus Opens Pandora's Box!

 

Apart from the headline reading as if Nature has hired a Daily Mail sub editor it's interesting stuff. Very large viruses with (for one at least) very low number of previously identified genes.

io9 - Scientists Freeze Light for an Entire Minute
 
The Actual Science Paper: Physical Review Letters - Stopped Light and Image Storage by Electromagnetically Induced Transparency up to the Regime of One Minute


In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute.
It sounds weird and it is. The reason for wanting to hold light in its place (aside from the sheer awesomeness of it) is to ensure that it retains its quantum coherence properties (i.e. its information state), thus making it possible to build light-based quantum memory. And the longer that light can be held, the better as far as computation is concerned. Accordingly, it could allow for more secure quantum communications over longer distances.

Needless to say, halting light is not easy — you can't just put in the freezer. Light is electromagnetic radiation that moves at 300 million meters per second. Over the course of a one minute span, it can travel about 11 million miles (18 million km), or 20 round trips to the moon. So it's a rather wily and slippery medium, to say the least.

But light can be slowed down and even halted altogether. And in fact, researchers once kept it still for 16 seconds by using cold atoms.

For this particular experiment, researcher Georg Heinze and his team converted light coherence into atomic coherences. They did so by using a quantum interference effect that makes an opaque medium — in this case a crystal — transparent over a narrow range of light spectra (a process called electromagnetically induced transparency (EIT)). The researchers shot a laser through this crystal (a source of light), which sent its atoms into a quantum superposition of two states. A second beam then switched off the first laser, and as a consequence, the transparency. Thus, the researchers collapsed the superposition — and trapped the second laser beam inside.

And they proved the accomplishment by storing — and then successfully retrieving — information in the form of a 100-micrometer-long picture with three horizontal stripes on it.

"The result outperforms earlier demonstrations in atomic gases by about six orders of magnitude and offers exciting possibilities of long-storage-time quantum memories that are spatially multiplexed, i.e., can store different quantum bits as different pixels," notes physicist Hugues de Riedmatten in an associated Physics Review article.

In future, the researchers will try to use different substances to increase the duration of information storage even further.

As I understand you, Raithe. They stopped light. But light is a constant universe wide. So they effectively shunted part of the universe out of kilter _with the entire rest of creation_. Meaning we as a species just divided the universe into two parts, one part slightly less old than the other.

 

I actually feel a bit dizzy just thinking about that.

I see some intelligence and security applications for that as well, if they can indeed turn opaque materials transparent in a nondestructive way. No need to drill holes for spy cams anymore ;)

The real future of intelligence is inductive/deductive 'creative' intelligence. Direct observation is always going to be too resource intensive.
