U.S. Cops To Become Brain Scanning Marijuana Detectors

If Mass General Hospital (MGH) has its way, law enforcement officers in the United States will soon be using portable functional near-infrared spectroscopy (fNIRS) scanners on motorists.

A recent Boston Globearticle describes fNIRS as a “breakthrough” in detecting marijuana impairment.

“Boston researchers say they’ve developed a new, noninvasive technique for detecting marijuana highs that can reliably tell the difference between people who are truly impaired by the drug and those who merely used it recently.”

What has happened to so-called Drug Recognition Experts (DRE)? Have the courts finally realized that police officers using pupil dilation charts to determine which type of drugs a motorist is under is junk science?

Nope, because soon, DRE police officers across the country will be using pupil dilation charts and portable fNIRS brain scanners to determine if someone is under the influence of drugs.

“For so long, our model has been alcohol, so there’s been a lot of focus on breath and blood levels,” Dr. Jodi Gilman, who led the research, said. “Our thought was, ‘What about looking directly at the brain?’ “

The MGH study claims that fNIRS scanners are accurate 76 percent of the time.

Quantum leap: Has next-gen computing moved from hype to hope?

Australian scientists believe they have taken a key step towards building a silicon quantum computer – a device that could take quantum computing from hype to mainstream.

Silicon quantum computers marry quantum technology with the same element – silicon – used in existing computer chips, so can hopefully be easily mass-produced. Australia leads the world in the technology, which competes with at least eight other types of quantum computer.

But despite a decade of hype and billions of dollars in investment, quantum computing in general remains a long way off fulfilling its full promise, experts admit. At this stage, there are few uses for such a computer and scientists remain a long way from building a device that could calculate serious equations.

The Australian-led study, published on the front cover of leading journal Nature in January, shows silicon quantum computers can now be operated with better than 99 per cent accuracy.

“This has long been understood as the next big step you needed to take,” says Professor Andrea Morello of the University of NSW, who led the work.

Being 99 per cent-plus accurate seems a small achievement for a computer, but it’s a big deal in quantum because it is considered the threshold at which you could scale quantum processors into an actual computer, he says.

New DARPA Black Hawk A.I. War Machines Set to Take to the Skies

Anyone who has been following Activist Post for any length of time knows that we continue to sound the alarm about how the military has been working on A.I. systems that will increasingly become fully autonomous — it’s part of the Internet of Battlefield Things. The only area seemingly left up for debate is whether these machines will be unleashed without any human input whatsoever in the decision-making process.

Now that we are seeing the rollout of robo-dogs on the border and tests of putting them on American streets, any advancement in A.I. war capabilities should be assumed to eventually trickle down from foreign lands into the United States. Remember, it used to be a conspiracy theory back in the early 2000s that standard drones would ever fly over America.

Now Defense One is reporting that A.I.-infused Black Hawk helicopters have made an advancement to the extent where they can autonomously carry out a directive set by a commanding officer. This also raises the question of how many of these can be commanded by one human. We recently saw a demo of a drone swarm consisting of 130 separate drones being managed by a single human operator utilizing virtual reality.

‘Black Mirror-Like’ Robo-Dogs Patrol US Border, Searching For Illegals

President Biden’s southern border crisis isn’t going away anytime soon as Republicans stress the need to beef up border security amid a flood of illegals crossing into the US. The Department of Homeland Security (DHS) recently adopted quadrupedal machines to patrol the border’s harsh landscape, extreme temperatures, and dangerous obstacles to search for illegals. 

DHS’ research and development team, the Science & Technology Directorate (S&T), released a statement on Tuesday specifying the use of Ghost Robotics’ robot dog ‘Ghost Vision 60’ by the Customs and Border Protection (CBP) on the southern border to test new surveillance methods. The robot dog’s appearance is eerily similar to the rover dogs in the popular dystopian Netflix series “Black Mirror.” 

“The southern border can be an inhospitable place for man and beast, and that is exactly why a machine may excel there,” said S&T program manager, Brenda Long. “This S&T-led initiative focuses on Automated Ground Surveillance Vehicles, or what we call ‘AGSVs.’ Essentially, the AGSV program is all about…robot dogs.”

Researchers regrow frog’s lost leg

For millions of patients who have lost limbs for reasons ranging from diabetes to trauma, the possibility of regaining function through natural regeneration remains out of reach. Regrowth of legs and arms remains the province of salamanders and superheroes.

But in a study published in the journal Science Advances, scientists at Tufts University and Harvard University’s Wyss Institute have brought us a step closer to the goal of regenerative medicine.

On adult frogs, which are naturally unable to regenerate limbs, the researchers were able to trigger regrowth of a lost leg using a five-drug cocktail applied in a silicone wearable bioreactor dome that seals in the elixir over the stump for just 24 hours. That brief treatment sets in motion an 18-month period of regrowth that restores a functional leg.

Many creatures have the capability of full regeneration of at least some limbs, including salamanders, starfish, crabs, and lizards. Flatworms can even be cut up into pieces, with each piece reconstructing an entire organism. Humans are capable of closing wounds with new tissue growth, and our livers have a remarkable, almost flatworm-like capability of regenerating to full size after a 50% loss.

But loss of a large and structurally complex limb—an arm or leg—cannot be restored by any natural process of regeneration in humans or mammals. In fact, we tend to cover major injuries with an amorphous mass of scar tissue, protecting it from further blood loss and infection and preventing further growth.

China Unveils ‘World’s Largest’ Quadruped Military Robot

China has introduced what it claims to be the world’s largest electrically-powered quadruped robot to assist the military on logistics and reconnaissance missions.

With a “yak-like appearance,” the four-legged robot can reportedly carry up to 352 pounds (160 kilograms) of payload and run at six miles (10 kilometers) per hour.

The platform’s structure is designed to withstand challenging off-grid military missions and conquer a wide variety of terrain, including cliffs, trenches, grasslands, fields, deserts, snow, and muddy roads.

Despite being reported as the heaviest and largest quadruped robot, the hi-tech unit can run, jump, turn, and walk diagonally.

According to state broadcaster China Central Television (CCTV), the platform has 12 modules and state-of-the-art sensors, allowing it to collect tactical battlefield information and perform logistics.

Potential military uses include all-weather operations in high-risk combat zones, remote border areas, and complex environments that have proven too challenging for soldiers.

Emirates president calls 5G rollout fiasco the ‘most delinquent mess he’s seen in his entire career’ and blames Pete Buttigieg for doing nothing to stop the chaos after dozens of flights were canceled – and then uncanceled

The president of Emirates has slammed the 5G fiasco as the ‘most delinquent, irresponsible’ mess he has seen in his 50-year aviation career and blamed it on Transport Secretary Pete Buttigieg, who he says knew about the impending chaos but failed to warn anyone in time to stop it. 

AT&T and Verizon launched their 5G network across America on Wednesday morning, switching on 4,500 towers to bring faster wireless to their customers. They had to hold back on ten percent of the towers – 500 – that are near airports because the frequencies the towers emit could interfere with the signal on some planes. 

Eighty-eight airports now have buffers to protect against it but some major airports like Boston and Memphis do not. In the most recent FAA announcement on Wednesday afternoon, the government said ’62 percent’ of flights could operate safely – leaving nearly half to reschedule.

On Wednesday, some airline passengers who were unaware of the fiasco showed up at airports ready to board their flights but were told they had been canceled. Air India, Emirates, BA, Japan Airlines and All Nippon canceled flights on Tuesday, then rushed to bring them back on Wednesday. 

In total, 239 flights to, from and within the US have been canceled so far. It’s unclear if all have been scrapped because of 5G, but the network launch is causing major issues.

It had a detrimental effect on Boeing, whose 777 and 787 planes are the ones affected and which has lucrative contracts with both the government and with the airlines; stocks fell by three percent on Wednesday as a result of the fiasco.

Sir Tim Clark, the president of Emirates, appeared on CNN, Wednesday that American airlines knew about the risks before the rest of the world, and that it forced them to scramble to cancel flights then bring them back once it was safe. 

President Biden, at a rare press conference on Wednesday afternoon, shrugged off responsibility for the fiasco and instead tried to take credit for brokering the deal.

The FBI’s Honeypot Phones Were More Widely Distributed in the U.S. Than Previously Thought

One of the weirder stories from last year involved a gargantuan FBI honeypot operation designed to catch crooks all over the world. According to Motherboard, that operation had a bigger imprint in the U.S. than originally believed.

During “Operation Trojan Shield,” the feds used a secret relationship with an encrypted phone company, called Anom, which sold devices exclusively to career criminals looking for a secure way to communicate with one another. The product’s developer, who had previously been busted for drug trafficking, agreed to act as a high-level federal informant and for at least two years sold devices to criminals while also secretly cooperating with authorities. Meanwhile the FBI, along with its international partners, intercepted all of the communications, which allowed them to capture evidence of widespread criminal malfeasance on a global scale.

It made for one helluva weird story when the bureau finally revealed what it had been up to last June, and “Shield” led to the arrest of hundreds of alleged criminals in countries all around the world—many of which are accused of using the phones to organize drug trafficking and other forms of organized crime. The arrests continue to this day.

China’s $1 trillion ‘artificial sun’ fusion reactor just got five times hotter than the sun

China’s “artificial sun” has set a new world record after superheating a loop of plasma to temperatures five times hotter than the sun for more than 17 minutes, state media reported. 

The EAST (Experimental Advanced Superconducting Tokamak) nuclear fusion reactor maintained a temperature of 158 million degrees Fahrenheit (70 million degrees Celsius) for 1,056 seconds, according to the Xinhua News Agency. The achievement brings scientists a small yet significant step closer to the creation of a source of near-unlimited clean energy.

The Chinese experimental nuclear fusion reactor smashed the previous record, set by France’s Tore Supra tokamak in 2003, where plasma in a coiling loop remained at similar temperatures for 390 seconds. EAST had previously set another record in May 2021 by running for 101 seconds at an unprecedented 216 million F (120 million C). The core of the actual sun, by contrast, reaches temperatures of around 27 million F (15 million C).
