With the 2015 Chevrolet Impala Bi-Fuel, drivers can top off their tank with waste byproducts, almost like Dr. Emmett Brown — aka “Doc” — did with his time-traveling DeLorean in the movie “Back to the Future.”

But instead of dumping banana peels and backwash from a beer can directly into the DeLorean’s “Mr. Fusion” reactor (see the video clip below), Impala Bi-Fuel owners simply fill up on natural gas, some of which comes from biogas, Chevy points out in its announcement about the new full-size sedan arriving in dealerships soon.

NASA is already so impressed by the Starship that it has contracted SpaceX to build a lunar-landing version of it to return astronauts to the moon as early as 2024. The selection has enraged Musk’s rivals such as Blue Origin’s Jeff Bezos Jeffrey (Jeff) Preston BezosSeat on Bezos-backed space flight sells for million at auction Researchers: Wealth accumulation at Ivy League presents ‘fundamental threat to our democracy’ Democrats reintroduce bill to create ‘millionaires surtax’ MORE and has perturbed some members of Congress. Both have only themselves to blame — Blue Origin for offering an inferior design and Congress for underfunding the Human Landing System project.

Military technology development has often been defined by the advent of new ways to transport people and cargo. The racing galleon of the 16th century became the frigates and ships of the line that defined naval warfare in the 18th and early 19th centuries. The steam engine and iron and steel armor led to the dreadnoughts of the early 20th century. Modern warships incorporate nuclear power. Air travel has caused the same sort of evolution, from the motorized kites of World War I to modern jets that can deliver destruction and death from thousands of miles away.

Now, space transportation technology is poised to cause a similar revolution in the military’s ability to defend the United States and its allies and to inflict mayhem and death on any enemy that would propose to make war on America. The great irony is that the Starship will be used by a branch of the military that Musk once compared to Starfleet, the fictional service depicted in the “Star Trek” television shows and movies. The thought would likely bring a smile to the face of the franchise’s creator, Gene Roddenberry, in whatever afterlife one envisions him inhabiting.

Tesla halted car purchases with bitcoin in mid-May due to concerns over how mining contributes to climate change.

Scientists have long struggled to understand how common planets form. A new supercomputer simulation shows that the missing ingredient may be magnetism.

“These are novel living machines. They are not a traditional robot or a known species of animals. It is a new class of artifacts: a living and programmable organism,” says Joshua Bongard, an expert in computer science and robotics at the University of Vermont (UVM) and one of the leaders of the find.

As the scientist explains, these living bots do not look like traditional robots : they do not have shiny gears or robotic arms. Rather, they look more like a tiny blob of pink meat in motion, a biological machine that researchers say can accomplish things traditional robots cannot.

Xenobots are synthetic organisms designed automatically by a supercomputer to perform a specific task, using a process of trial and error (an evolutionary algorithm), and are built by a combination of different biological tissues.

Devices can multiplex and herald entanglement.

“Conditional witnessing” technique makes many-body entangled states easier to measure.

Quantum error correction – a crucial ingredient in bringing quantum computers into the mainstream – relies on sharing entanglement between many particles at once. Thanks to researchers in the UK, Spain and Germany, measuring those entangled states just got a lot easier. The new measurement procedure, which the researchers term “conditional witnessing”, is more robust to noise than previous techniques and minimizes the number of measurements required, making it a valuable method for testing imperfect real-life quantum systems.

Quantum computers run their algorithms on quantum bits, or qubits. These physical two-level quantum systems play an analogous role to classical bits, except that instead of being restricted to just “0” or “1” states, a single qubit can be in any combination of the two. This extra information capacity, combined with the ability to manipulate quantum entanglement between qubits (thus allowing multiple calculations to be performed simultaneously), is a key advantage of quantum computers.

Quantum mechanics describes this frustration by suggesting that the orientation of the spins is not rigid. Instead, it constantly changes direction in a fluid-like way to produce an entangled ensemble of spin-ups and spin-downs. Thanks to this behaviour, a spin liquid will remain in a liquid state even at temperatures near absolute zero, where most materials usually freeze solid.
