The ‘impossible’ EM Drive is about to be tested in space

Posted by in categories: physics, space travel

An actual EM Drive is about to be launched into space for the first time, so scientists can finally figure out — once and for all — if it really is possible for a rocket engine to generate thrust without any kind of exhaust or propellant.

Built by American inventor and chemical engineer, Guido Fetta, the EM Drive is as controversial as it gets, because while certain experiments have suggested that such an engine could work, it also goes against one of the most fundamental laws of physics we have.

As Newton’s Third Law states, “To each action there’s an equal and opposite reaction,” and many physicists say the EM Drive categorically violates that law.

OMEGA Laser Could Produce Nuclear Fusion at 5 Times Current Levels

Posted by in category: nuclear energy

Researchers from the University of Rochester have detailed conditions where the National Ignition Facility at Lawrence Livermore can create five times more nuclear fusion yield than the current records.

Nuclear fusion is one of the Holy Grails of energy research. However, developments in this particular field have been more like baby steps rather than great strides.

But now, one study is significantly accelerating our (unfortunately) small steps towards nuclear fusion. Researchers working on the OMEGA laser at the Rochester University’s Laboratory of Laser Energetics (LLE) have found optimal conditions that could produce a fusion yield that’s five times higher than the current record.

Scientists Created a Substance that Transforms Infrared into Visible Light

Posted by in category: futurism

A team of scientists from Germany were able to create a substance that converts infrared light into visible light. This development is a big step in the advancement of illumination technology.

Light is one of the primary things that allows humans to function effectively and efficiently. Indeed, without it, we are basically hopeless; however, a lot of it is…well, missing. Perhaps a better way of articulating it is by noting that a lot of light is invisible to us.

Light, or electromagnetic radiation, is actually a really wide spectrum, but only a small portion can be seen by humans. The region that we can see is called the visible spectrum because (duh) it is visible to us.

Biotech startup says it has nearly perfected making wine in a lab

Posted by in categories: biotech/medical, food

Ava Winery’s first public taste test didn’t exactly go well. Two reporters on camera at New Scientist compared the biotech startup’s artificial wine with a glass of the Moscato D’Asti that it was based on. They complained that the fake wine had too little color, too little viscosity, and an unpleasant plastic smell.

But that was May, and this is September, and Ava is already bragging about making huge improvements in its product, to the point where it is all but indistinguishable from fermented grape juice, and looking ahead to how it’s going to change the world.

“What we have done since then is leaps and bounds beyond what they were able to taste back in May,” co-founder Alec Lee says. “Now we’re at the point where about 90% of people fail out blind taste test.”

Ray Kurzweil: Accelerating Tech Is Making Old Intellectual Property Laws Obsolete

Posted by in categories: law, Ray Kurzweil, singularity

As technology and innovation move faster and faster, concerns over ownership and access continue to increase. In answer to a question at a Singularity University event, Ray Kurzweil suggested we need to rethink intellectual property laws to more realistically match today’s pace.

Intellectual property laws from the 19th century were envisioned with roughly 20-year cycles, he said, which was enough to give you a head-start on a new idea or invention and attract funding to see it through. But how relevant is a 20-year cycle today when a generation of technology can come and go in a year—and even that is set to speed up?

Drones armed with anti-laser lasers that trick controls of enemy lasers into missing the drone

Posted by in categories: drones, energy, military

To defend against military lasers, Adsys Controls of Irvine, California, has created Helios, which can be carried on drones. To do much damage, an offensive laser needs to remain focused on its target for several seconds. Helios stops a laser from doing this by disrupting the systems controlling the beam – the Achilles’ heel for all such weapons. “Beam control is a critical function of high-energy lasers,” says Adsys CEO Brian Goldberg.

Helios can detect an incoming laser beam and identify its key characteristics, such as power, wavelength, pulse frequency and its source. Helios then interferes with the beam control – possibly by firing back a low-power laser of its own – so the attacking laser cannot fix on the target. “It provides permanent protection,” says Goldberg. “It’s not just buying time.”

He will not say exactly how the interference is done, but it may involve fooling the control system into thinking it is hitting its target despite the laser actually pointing a few metres to the side. A direct hit would have produced a big burst of reflected light, so a pulse sent back by an anti-laser laser could make it look like the original laser was on target.
