A robot has built a prototype launch-and-landing pad in Hawaii, potentially helping pave the way for automated construction projects on the moon and Mars.

The robotic rover, named Helelani, assembled the pad on Hawaii’s Big Island late last year, putting together 100 pavers made of locally available material in an effort to prove out technology that could do similar work in space.

“The construction project is really unique. Instead of concrete for the landing pad, we’re using lunar and Mars material, which is exactly like the material we have here on the Big Island — basalt,” Rob Kelso, executive director of the Pacific International Space Center for Exploration (PISCES) in Hawaii, told Hawaiian news outlet Big Island Now. PISCES partnered with NASA on the project, which is part of a larger program called Additive Construction with Mobile Emplacement, or ACME for short. [The Boldest Mars Missions in History].

Paul March also endorsed the technical information and insights of forum member Rodal on the topic of EMdrive. Rodal indicates the differences in dielectric materials and other nuances of interpreting the known results.

A radio frequency (RF) resonant cavity thruster is a proposed new type of electromagnetic thruster. Unlike conventional electromagnetic thrusters, a resonant cavity thruster would use no reaction mass, and emit no directional radiation.

A few variations on such thrusters have been proposed. Aerospace engineer Roger Shawyer designed the EmDrive in 2001, and has persistently promoted the idea since then through his company, Satellite Propulsion Research.

They’re taking over everything.

YES PLEASE.

It’s 7.5 times lighter than air, and a cubic metre of the stuff weighs just 160 grams. It’s 12 percent lighter than the second lightest material in the world – aerographite – and you can balance a few cubic centimetres of the stuff on a dandelion head. Water is about 1,000 times as dense.

Now, we’re hitting Terminator mode with this.

If you’re worried that artificial intelligence will take over the world now that computers are powerful enough to outsmart humans at incredibly complex games, then you’re not going to like the idea that someday computers will be able to simply build their own chips without any help from humans. That’s not the case just yet, but researchers did come up with a way to grow metal wires at a molecular level.

At the same time, this is a remarkable innovation that paves the way for a future where computers are able to create high-end chip solutions just as a plant would grow leaves, rather than having humans develop computer chips using complicated nanoengineering techniques.

“With the operational function that we have proposed in these memory cells, there will be no need for time-consuming magnetization and demagnetization processes. This means that read and write operations will take only a few hundred picoseconds, depending on the materials and the geometry of the particular system, while conventional methods take hundreds or thousands of times longer than this,” said the study author Alexander Golubov, the head of Moscow Institute of Physics and Technology (MIPT)’s Laboratory of Quantum Topological Phenomena in Superconducting Systems.

Golubov and colleagues at Moscow State University have proposed creating basic memory cells based on quantum effects in superconductor “sandwiches.” Superconductors were predicted in the 1960s by the British physicist Brian Josephson. The electrons in these “sandwiches,” called “Josephson junctions,” are able to tunnel from one layer of a superconductor to another, passing through the dielectric like balls passing through a perforated wall.

Today, Josephson junctions are used both in quantum devices and conventional devices. For example, superconducting qubits are used to build the D-wave quantum system, which is capable of finding the minima of complex functions using the quantum annealing algorithm. There are also ultra-fast analogue-to-digital converters, devices to detect consecutive events, and other systems that do not require fast access to large amounts of memory. There have also been attempts to use the Josephson Effect to create ordinary processors. An experimental processor of this type was created in Japan in the late 1980s. In 2014, the research agency IAPRA resumed its attempts to create a prototype of a superconducting computer.

Airless tires.

#Airless_tires are the next generation of tires waiting to take over the world. Recently, #Hankook_iFlex_tire underwent a series of high speed tests and that has helped us take a step closer to a future where tires without air would become a reality. It was company’s fifth attempt at launching #airless_tires into the market. Why is the company trying to do so and that too this religiously? Because of the multiple benefits that this gadget brings in comparison to the traditional tires.

#Hankook’s tire is far more energy efficient and can be recycled as well. The material that has been used by Hankook allows the company to reduce the production steps into half as compared to a conventional tire.

Even if we don’t create a true AI for a thousand years, these algorithms, pared with our exponentially increasing computing power, could have much of the same effect on our civilization as the more traditional, AI-centric type Singularity. Very, very soon.

Replacing inefficient experimentation, UConn researchers have used machine learning to systematically scan millions of theoretical compounds for qualities that would make better materials for solar cells, fibers, and computer chips.

Chinese scientists have developed a nano-sized electric generator that can disappear without a trace inside the human body over time, a breakthrough they claim will bring biodegradable implants on microchips closer to reality.

The technology, reported on the latest issue of Science Advances journal, will have a wide range of applications as it can generate electric pulses to repair damaged neurons and power “brain chip” implants for soldiers in the future, pundits said.

At present, most implants must be surgically removed at the end of their lifespan. To address this issue, a number of small electric devices made from biodegradable materials that can absorbed by the human body after use have been developed around the world.
