Once you get to mach 5+ hypersonic speed, then a scramjet works and it is by far the most efficient type of engine for hypersonic speeds. A scramjet needs some other form of propulsion to get it to Mach 5. As a result, scramjets have become something of a well-studied technology in search of a practical application.

To reach these hypersonic speeds, Michael Smart, professor of hypersonics at the University of Queensland in Brisbane plans to combine an uncrewed scramjet with conventional rockets. He believes his Spartan launch system could radically reduce the costs of blasting satellites into orbit.

“All conventional satellite launch systems use different stages,” says Smart. “There’ll be a first stage rocket that normally gets up to Mach 5 or 6, you’ll have a second scramjet stage that goes two thirds of the way to space and you’ll have a final upper stage that takes the satellite into orbit.”

Today, SpaceX filed with the FCC to obtain the rights to operate 4,400 satellites to offer internet services from orbit, a plan that was announced last year.

Elon Musk’s trust currently owns 54% of the outstanding stock of SpaceX and has voting control of 78% of the outstanding stock of SpaceX.

Controlling artificial intelligence devices by voice will come soon said AI expert Neil Jacobstein.

Artificial intelligence is set to transform the world, the audience at a Christchurch conference on the future was told.

Artificial intelligence (AI) “allows us to expand the range of the possible, to do things we never thought we could do before,” said Neil Jacobstein who chairs the artificial intelligence and robotics track at Singularity University, a think tank based in California.

Luv it! Wait until we make the marriage of QC meets Synbio — QC for the infrastructure and communications, and Synbio makes us all connected.

Cambridge, MA (Scicasts) — Synthetic biology allows scientists to design genetic circuits that can be placed in cells, giving them new functions such as producing drugs or other useful molecules. However, as these circuits become more complex, the genetic components can interfere with each other, making it difficult to achieve more complicated functions.

MIT researchers have now demonstrated that these circuits can be isolated within individual synthetic “cells,” preventing them from disrupting each other. The researchers can also control communication between these cells, allowing for circuits or their products to be combined at specific times.

DALLAS — AT&T is experimenting with artificial intelligence (AI) and combining it with software-defined networking (SDN) and network functions virtualization (NFV) to figure out a better way to run its network.

Speaking on a panel at the 5G North America conference, Brian Daly, director of core network and government regulatory for AT&T, said that the company is looking at AI as a way to operate its network more efficiently by using it to make decisions that currently might require human interaction today. “We see AI combined with SDN and NFV as a way to provide us with efficiencies that may not exist today,” Daly said.

Scientists have discovered an antibody produced by an HIV-positive patient that neutralises 98 percent of all HIV strains tested — including most of the strains that are resistant to other antibodies of the same class.

Due to HIV’s ability to rapidly respond to the body’s immune defences, an antibody that can block a wide range of strains has been very hard to come by. But now that we’ve found one, it could form the basis of a new vaccine against the virus.

Researchers from the US National Institutes of Health (NIH) found that the antibody, called NG, was able to maintain its ability to recognise the HIV virus, even as the virus morphed and broke away from it.

Lenses with a surface accuracy in the nanometer range are behind ever more accurate laser and optical systems. Manufacturers depend on ultra-precise optical and mechanical ablation processes, innovative coating processes and extremely accurate measuring technology to venture into these nano-worlds. The latest trends in optical manufacturing will be showcased by the world’s leading trade fair LASER World of PHOTONICS, from June 26–29, 2017 in Munich.

The diversity of lenses, their shapes, sizes and materials is growing all the time. Applications in non-visible wavelengths from x-rays and ultraviolet to the far infrared also require special optics, such as material processing using short pulse and ultrashort pulse lasers or imaging techniques in the medical and research fields and industrial quality control.
