Nature is the ultimate quantum computer.
A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid.
University of Waterloo professor Michael Tam and his Ph.D. students Yi Wang and Weinan Zhao have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment. In the journal Nature Water Tam and his team discuss several promising new water collection and purification technologies.
Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.
Joint lead researcher and Ph.D. student, Vanessa Olaya Agudelo, said, It is by understanding these basic processes inside and between molecules that we can open up a new world of possibilities in materials science, drug design, or solar energy harvesting.
It could also help improve other processes that rely on molecules interacting with light, such as how smog is created or how the ozone layer is damaged.

In June, Chanos — who won big bets on the downfall of US energy group Enron and the German payments company Wirecard — announced that his eponymous investment firm is raising several hundred million dollars for a fund that will take short positions in US-listed data centre groups.

Today’s cars can contain over 100 computers and millions of lines of software code, which are all networked together and can operate all aspects of your vehicle. It is only logical that following this shift, car theft has gone high-tech.
According to Techxplore, the computers in a vehicle can be divided into four categories; The majority are dedicated to operating the vehicle’s drive train-controlling the fuel, the battery, monitoring emissions, and operating cruise control. The second category is for safety-collecting data from in and around the vehicle for functions like lane correction, automatic braking, and backup monitoring. The third category is information-entertainment systems that provide music and video and can interface with personal devices through Bluetooth. The last category is the navigation system.
The Human Brain Project wraps up in September after a decade. It had notable achievements and a troubled past.
Using natural quantum interactions allows faster, more robust computation for Grover’s algorithm and many others.
Los Alamos National Laboratory scientists have developed a groundbreaking quantum computing.
Performing computation using quantum-mechanical phenomena such as superposition and entanglement.

Quantum computing is still really, really hard. But the rise of a powerful class of error-correcting codes suggests that the task might be slightly more feasible than many feared.
How looks life with na implant in brain.
Brain-computer interface technology is a fast-growing field but how does it feel to live with an implant inside of you?
In 2014, Ian Burkhart looked down at his hand and imagined closing it. To his astonishment, his hand did just that.
This was the first time a paraplegic person had regained the ability to move his arm by the sheer force of his thought, assisted by an implant in his brain.
In their 1982 paper, Fredkin and Toffoli had begun developing their work on reversible computation in a rather different direction. It started with a seemingly frivolous analogy: a billiard table. They showed how mathematical computations could be represented by fully reversible billiard-ball interactions, assuming a frictionless table and balls interacting without friction.
This physical manifestation of the reversible concept grew from Toffoli’s idea that computational concepts could be a better way to encapsulate physics than the differential equations conventionally used to describe motion and change. Fredkin took things even further, concluding that the whole Universe could actually be seen as a kind of computer. In his view, it was a ‘cellular automaton’: a collection of computational bits, or cells, that can flip states according to a defined set of rules determined by the states of the cells around them. Over time, these simple rules can give rise to all the complexities of the cosmos — even life.
He wasn’t the first to play with such ideas. Konrad Zuse — a German civil engineer who, before the Second World War, had developed one of the first programmable computers — suggested in his 1969 book Calculating Space that the Universe could be viewed as a classical digital cellular automaton. Fredkin and his associates developed the concept with intense focus, spending years searching for examples of how simple computational rules could generate all the phenomena associated with subatomic particles and forces3.
That early experience drove his professional interest in helping people communicate.
Now, Henderson’s an author on one of two papers published Wednesday showing substantial advances toward enabling speech in people injured by stroke, accident or disease.
Although still very early in development, these so-called brain-computer interfaces are five times better than previous generations of the technology at “reading” brainwaves and translating them into synthesized speech. The successes suggest it will someday be possible to restore nearly normal communication ability to people like Henderson’s late father.
