NASA Revealed Google Created World’s Most Powerful Computer … And Then Publication Vanishes 

Google’s new quantum computer reportedly spends mere minutes on the tasks the world’s top supercomputers would need several millennia to perform. The media found out about this after NASA “accidentally” shared the firm’s research.

The software engineers at Google have built the world’s most powerful computer, the Financial Times and Fortune magazine reported on Friday, citing the company’s now-removed research paper. The paper is said to have been posted on a website hosted by NASA, which partners with Google, but later quietly taken down, without explanation.

Google and NASA have refused to comment on the matter. A source within the IT giant, however, told Fortune that NASA had “accidentally” published the paper before its team could verify its findings.

In the research, Google reportedly claimed that it takes their new quantum processor just around 200 seconds to make calculations that existing supercomputers would require around 10,000 years to perform. They also said the processor requires mere 30 seconds to complete a task the Google Cloud server would need 50 trillion hours to do.

Quantum computing allows evaluating multiple possibilities at once and performing complex calculations not possible on normal computers. So, if proven true, Google’s new processor would be a real breakthrough, propelling the firm way ahead of giants like Microsoft, IBM and Intel, all of whom compete in building quantum processors.

Quantum processors will help create new, advanced chemicals and develop next-level artificial intelligence, among other things.

Nikola Tesla patented a Drone in 1898

A little over a century ago, physicist and engineer Nikola Tesla had devised a “machine” with the ability to fly over cities to deter humans from causing conflict. The first drone? Nikola Tesla patented a Drone?

Nikola Tesla patented a Drone

Nikola Tesla was a genius and a man ahead of his time. Not only did he manage to change the world with revolutionary inventions such as alternating current, but his imagination allowed him to anticipate his time by predicting the creation of television or cordless phones.

But he did not stay there, because as the technologist Matthew Schroyer has discovered investigating his patents, the Serbian inventor, engineer and physicist also described the current combat drones.

He spoke of them as machines or ships that could be remotely controlled, and that would sow peace in the world thanks to their destructive power.

In his patent “Method and apparatus for controlling the mechanism of ships or moving vehicles” granted on November 8, 1898, Tesla wrote that his invention would not require cables or electrical conductors.

It was, therefore, a ship or vehicle that could be controlled through waves, impulses or radiations that would be sent to it through land, water or air. A drone.

At that time radio waves were a novelty, were described in 1867, and began to be used for communication in the 1890s.

Tesla saw in them a great potential, and not only to send packages and supplies such as drones that Amazon is designing but also as a combat weapon like UAVs used by some governments.(Nikola Tesla patented a Drone)

In the patent, Tesla wrote that it could be used to “carry letters, packages, supplies, instruments, objects or any type of material, and to establish communication with inaccessible regions or explore the conditions in them.”

To that, I added that it could also be used to “kill or capture whales or other animals of the ocean, and for many other scientific, engineering or commercial purposes.”

“But the greatest value of my invention will be its effect on war and weaponry,” writes Tesla. “Because of its safe and unlimited destructive power, it will tend to provoke and maintain permanent peace among nations.”

The peace we do not know if they will bring it, but the current combat drones have much in common with what the Serbian inventor patented more than a century ago. What do you think?

Relativistic Speeds Could be Reached With ‘Helical engine’

NASA engineer David Burns has developed a concept for a new drive capable of reaching distant solar systems.

Traversing the vast distances between stars is undoubtedly a major problem – even reaching our nearest neighbor with today’s technology would take thousands of years.

But what if it was possible to travel such distances in a fraction of the time ?

Enter David Burns – a NASA engineer with a concept for a new type of propulsion system that can theoretically reach 99% of the speed of light without needing any sort of propellant.

Known as the ‘helical engine’, this exotic drive works by exploiting the change in mass that occurs at relativistic speeds as described in Einstein’s special theory of relativity.

The idea has drawn comparisons to aerospace engineer Roger Shawyer’s controversial EmDrive.

“The engine accelerates ions confined in a loop to moderate relativistic speeds, and then varies their velocity to make slight changes to their mass,” Burns writes. “The engine then moves ions back and forth along the direction of travel to produce thrust.”

“The engine has no moving parts other than ions traveling in a vacuum line, trapped inside electric and magnetic fields.”

While the drive only exists on paper at the moment, the idea behind it is certainly interesting.

Whether it will actually work in practice however remains to be seen.

Brain Size May Increase with Exercise, According to Study

Aerobic exercise can improve memory function and maintain brain health as we age, a new Australian-led study has found.

In a first of its kind international collaboration, researchers from Australia’s National Institute of Complementary Medicine at Western Sydney University and the Division of Psychology and Mental Health at the University of Manchester in the UK examined the effects of aerobic exercise on a region of the brain called the hippocampus, which is critical for memory and other brain functions.

Brain health decreases with age, with the average brain shrinking by approximately five per cent per decade after the age of 40.

Studies in mice and rats have consistently shown that physical exercise increases the size of the hippocampus but until now evidence in humans has been inconsistent.

The researchers systematically reviewed 14 clinical trials which examined the brain scans of 737 people before and after aerobic exercise programs or in control conditions.

The participants included a mix of healthy adults, people with mild cognitive impairment such as Alzheimer’s and people with a clinical diagnosis of mental illness including depression and schizophrenia. Ages ranged from 24 to 76 years with an average age of 66.

The researchers examined effects of aerobic exercise, including stationary cycling, walking, and treadmill running. The length of the interventions ranged from three to 24 months with a range of 2-5 sessions per week.

Overall, the results – published in the journal NeuroImage – showed that, while exercise had no effect on total hippocampal volume, it did significantly increase the size of the left region of the hippocampus in humans.

Lead author, NICM postdoctoral research fellow, Joseph Firth said the study provides some of the most definitive evidence to date on the benefits of exercise for brain health.

“When you exercise you produce a chemical called brain-derived neurotrophic factor (BDNF), which may help to prevent age-related decline by reducing the deterioration of the brain,” Mr. Firth said.

“Our data showed that, rather than actually increasing the size of the hippocampus per se, the main ‘brain benefits’ are due to aerobic exercise slowing down the deterioration in brain size. In other words, exercise can be seen as a maintenance program for the brain.”

Mr. Firth said along with improving regular ‘healthy’ aging, the results have implications for the prevention of aging-related neurodegenerative disorders such as Alzheimer’s and dementia – however further research is needed to establish this.

Interestingly, physical exercise is one of the very few ‘proven’ methods for maintaining brain size and functioning into older age.

The paper, “Effects of aerobic exercise on hippocampal volume in humans: a systematic review and meta-analysis” is available online here.
