ADELPHI, Md. — Last year had its share of science and technology advances from Army researchers. The U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory, the Army’s corporate research laboratory, has the mission to operationalize science for transformational overmatch.

“The COVID-19 pandemic challenged us all this year,” said the lab’s chief scientist, Dr. Alexander Kott. “Despite that, our scientists and researchers made groundbreaking discoveries in 2020 that will strengthen and protect our future Soldiers.”

The lab’s leading scientists picked the coolest advances to showcase how Army scientists and researchers are supporting the Soldier of the future with a top 10 list from 2020. View the Top 10 video on YouTube: https://youtu.be/6sg-4CxNbBk

Number 10: X-ray-like imaging system to see through barriers

How about Superman-like X-ray vision in the form of goggles for Soldiers? New Army-funded research is looking at how to make this a reality.

Researchers created an imaging system to see objects through environmental barriers, like sand. They shine an ultra-fast laser through a barrier and read back the reflected photons, assembling an image of what was behind the barrier in just fractions of a second.

Existing imaging capabilities are limited to relaying back objects in two dimensions, but this new research will show objects in three dimensions, giving Soldiers more accurate situational and threat awareness in degraded visual environments. This could help future pilots fly through sandstorms, and robots navigate through fog.

“Previous efforts were at very small distances, and with very heavy and complex methodology,” said Army researcher Dr. Hamid Krim. “This is more of a macro scale, and it could be used on large or small moving platforms.”

Number 9: Levitating, freezing atoms to further quantum networking

Using laser beams, Army researchers levitate atoms and freeze them to the coldest temperatures on earth, nearly absolute zero. Patterns of quantum information are stored in the frozen atoms, creating quantum holograms that can be retrieved. From this, researchers developed a new way to solve a critical challenge in quantum entanglement.

The resulting holographic quantum memory is a building block for future Army quantum networks with exponentially more powerful capabilities in computing, sensing and communications.

“Quantum networks are completely different than anything that currently exists,” said Army researcher Kevin Cox. “The internet is the network right now, and it possesses certain capabilities. Quantum networks will have completely different capabilities and will access a piece of the universe that we have not been able to access before. It will lead to computing power that will be orders of magnitude more powerful than anything that currently exists.”

Number 8: An ultra-thin, flexible switch to access highest 5G frequencies

A new ultra-thin radio-frequency switch could provide access to the highest 5G frequencies and enable 6G connectivity and beyond.

Building off a material the Army discovered 10 years ago, research partners developed an atomic switch that is capable of connecting to the best available frequencies. It is more than 100 times more energy-efficient than what is used today and can transmit data at speeds up to 100 gigabits per second–speeding up how quickly users can do things like stream high-definition media and increasing average battery life substantially.

“This switches between frequencies, similar to tuning frequencies on a radio,” said Army researcher Dr. Chakrapani Varanasi. “The increased bandwidth and frequency range are unmatched–yet it consumes a fraction of the energy than what is currently used.”

The one-atom-thick switch is a fraction of a nanometer, and flexible, so it is easily integrated onto wearable systems as a laminate on Soldiers’ uniforms with negligible extra weight. This could revolutionize the way the Army communicates, and could be integrated into satellite systems, smart radios and across the Internet of Things.

Number 7: Autonomous sensors configuring mesh radio network

Imagine autonomous, independent sensors could create their own radio network in a remote location. Army scientists are working on technology that will provide Soldiers with situational awareness through a unique autonomous mesh networking solution. Dropped sensors on a battlefield autonomously form their own network to route communications back to a place of interest, whether it is a command post or a lone Soldier.

This radio network created on-the-fly requires little to no user intervention, adapts to local conditions and is more than 20 times more energy efficient than conventional Army radios–meaning Soldiers can carry less and communicate better.

“Soldiers carry so much weight, and radio and batteries comprise a significant amount of that load,” said Army researcher Ron Tobin. “A capability like this could be much more energy-efficient, which could improve communications for longer durations but also lighten the load for Soldiers.”

Number 6: Real-time object detection model

Like autonomous cars are able to detect their surroundings, Soldiers need real-time scene understanding at the tactical edge. Using artificial intelligence and machine learning, Army researchers developed a novel object recognition model to immediately detect objects of interest.

Sensors deployed on platforms such as drones or ground vehicles capture images and video. The model locates and identifies these objects, processing information on the spot–even where computational processing is limited. Soldiers are then alerted to suspicious activities in the surrounding area.

“Our model can process five to six frames per second, which is comparable to the current state-of-the-art,” said Army researcher Dr. Heesung Kwon. “But we use multiple classifiers that can detect objects better than existing models.”

This capability enables rapid decision-making, reducing mission risk, and could be integrated into future Soldier eyewear.

Number 5: Electrical nudge to help brain

Sometimes we could all use a little stimulation to kick-start our brains. Army and academic researchers found how a subtle electrical nudge helps the brain reorganize its activity to rapidly adapt and better make decisions. Inspired by dynamic network techniques, researchers used this nudge to bypass the normal human sensory and cognitive pathways.

“This is changing the information flow through connections in the brain and can help us understand how the brain operates, especially in groups,” said Army researcher Dr. Javier Garcia.

This research lays the groundwork for improved teaming with intelligent agents–with possible future neuro-technologies that could prevent or predict behavioral mistakes or assess individual cognitive performance to keep our Soldiers sharp.

Number 4: AI to predict aircraft damage and failure

Army helicopters perform some of the most daring maneuvers in some of the most dangerous places in the world. Keeping the fleet in peak performing condition is critical.

Army researchers studied 15 years of flight patterns–more than 1.3 million flights from 4,000 UH-60 Black Hawk helicopters–and identified more than 100 different types of maneuvers. They connect which specific aircraft parts undergo the most wear and tear during these maneuvers. The result is a robust AI model predicting with nearly 100% accuracy which critical parts will fail, how and when.

“We know critical parts on an aircraft have finite life,” said Army researcher Dr. Mulugeta Haile. “We can use this data to effectively predict the best time to maintain an aircraft–by looking at how it has been flown rather than how much it has been flown.”

This significantly reduces costs to sustain the existing fleet–and most importantly, also identifies catastrophic damage before failure, improving mission outcomes and protecting our pilots.

Number 3: Intelligent swarming drones

Researchers look to nature to emulate the perfect dynamic flying formation.

Army and academic researchers develop autonomous, omniscient-like, swarming drones that can reason and make the best decisions without human interference. Equipped with cameras, these drones look around and see each other, and independently reason about each other’s size, distance and motion. The agents then communicate with each other. Through a form of machine learning, they imitate each other and decide how to reach the ideal collective goal.

“The agents have to learn how to process what they see, how to talk to each other and how to move, all through imitation,” said Army Senior Research Scientist Dr. Brian Sadler.

This could lead to completely autonomous cohesion and decision-making to assist our Soldiers in the most critical situations.

Number 2: 3D printed munitions

3D printing revolutionized the convenience and speed at which everyday people create everyday objects. Army scientists pioneer the 3D printing frontier with first-of-its-kind polymers for energetics and metals–including the highest-strength steel ever made–to develop the next generation of munitions.

They were first in the world to demonstrate 3D structural circuit manufacturing that will revolutionize munition fusing and sensing, while also saving weight and space.

“We are printing materials no one else has ever printed, and new geometric designs that open up the trade space for munitions,” said Army researcher Dr. Jason Robinette.

But how durable are they? These 3D printed munitions have high-G survivability–withstanding the most extreme accelerations that even current munitions can’t match. This will help soldiers in extreme environments and tomorrow’s battlefield.

Number 1: Intelligent, navigating munitions

Army researchers use the latest technologies to create the most intelligent munitions that navigate to and hit moving targets. With onboard sensors, actuators, and an imager, a munition runs an algorithm on the tip of the artillery piece as it flies to its target.

Current systems rely on GPS to navigate to a specified coordinate. This munition enables moving the flight path–both in initial guidance and mid-flight–improving the munition’s range and speed to hit a moving target.

“This research will enable us to penetrate faster and have more maneuverability so that we can evade threat systems and reach the target,” said Army researcher Dr. Frank Fresconi.

This will be a crucial element to ensure the Army’s dominance on land, on sea, and in the air.

CDC Warns Thousands Of Children Sent To ER After Taking Common Sleep Aid

Authored by Jack Phillips via The Epoch Times (emphasis ours),

A U.S. Centers for Disease Control (CDC) paper released Thursday found that thousands of young children have been taken to the emergency room over the past several years after taking the very common sleep-aid supplement melatonin.

The agency said that melatonin, which can come in gummies that are meant for adults, was implicated in about 7 percent of all emergency room visits for young children and infants “for unsupervised medication ingestions,” adding that many incidents were linked to the ingestion of gummy formulations that were flavored. Those incidents occurred between the years 2019 and 2022.

Melatonin is a hormone produced by the human body to regulate its sleep cycle. Supplements, which are sold in a number of different formulas, are generally taken before falling asleep and are popular among people suffering from insomnia, jet lag, chronic pain, or other problems.

The supplement isn’t regulated by the U.S. Food and Drug Administration and does not require child-resistant packaging. However, a number of supplement companies include caps or lids that are difficult for children to open.

The CDC report said that a significant number of melatonin-ingestion cases among young children were due to the children opening bottles that had not been properly closed or were within their reach. Thursday’s report, the agency said, “highlights the importance of educating parents and other caregivers about keeping all medications and supplements (including gummies) out of children’s reach and sight,” including melatonin.

The approximately 11,000 emergency department visits for unsupervised melatonin ingestions by infants and young children during 2019–2022 highlight the importance of educating parents and other caregivers about keeping all medications and supplements (including gummies) out of children’s reach and sight.

The CDC notes that melatonin use among Americans has increased five-fold over the past 25 years or so. That has coincided with a 530 percent increase in poison center calls for melatonin exposures to children between 2012 and 2021, it said, as well as a 420 percent increase in emergency visits for unsupervised melatonin ingestion by young children or infants between 2009 and 2020.

Some health officials advise that children under the age of 3 should avoid taking melatonin unless a doctor says otherwise. Side effects include drowsiness, headaches, agitation, dizziness, and bed wetting.

Other symptoms of too much melatonin include nausea, diarrhea, joint pain, anxiety, and irritability. The supplement can also impact blood pressure.

However, there is no established threshold for a melatonin overdose, officials have said. Most adult melatonin supplements contain a maximum of 10 milligrams of melatonin per serving, and some contain less.

Many people can tolerate even relatively large doses of melatonin without significant harm, officials say. But there is no antidote for an overdose. In cases of a child accidentally ingesting melatonin, doctors often ask a reliable adult to monitor them at home.

Dr. Cora Collette Breuner, with the Seattle Children’s Hospital at the University of Washington, told CNN that parents should speak with a doctor before giving their children the supplement.

“I also tell families, this is not something your child should take forever. Nobody knows what the long-term effects of taking this is on your child’s growth and development,” she told the outlet. “Taking away blue-light-emitting smartphones, tablets, laptops, and television at least two hours before bed will keep melatonin production humming along, as will reading or listening to bedtime stories in a softly lit room, taking a warm bath, or doing light stretches.”

In 2022, researchers found that in 2021, U.S. poison control centers received more than 52,000 calls about children consuming worrisome amounts of the dietary supplement. That’s a six-fold increase from about a decade earlier. Most such calls are about young children who accidentally got into bottles of melatonin, some of which come in the form of gummies for kids, the report said.

Dr. Karima Lelak, an emergency physician at Children’s Hospital of Michigan and the lead author of the study published in 2022 by the CDC, found that in about 83 percent of those calls, the children did not show any symptoms.

However, other children had vomiting, altered breathing, or other symptoms. Over the 10 years studied, more than 4,000 children were hospitalized, five were put on machines to help them breathe, and two children under the age of two died. Most of the hospitalized children were teenagers, and many of those ingestions were thought to be suicide attempts.

Those researchers also suggested that COVID-19 lockdowns and virtual learning forced more children to be at home all day, meaning there were more opportunities for kids to access melatonin. Also, those restrictions may have caused sleep-disrupting stress and anxiety, leading more families to consider melatonin, they suggested.

Red Candle In The Wind

By Benjamin PIcton of Rabobank

February non-farm payrolls superficially exceeded market expectations on Friday by printing at 275,000 against a consensus call of 200,000. We say superficially, because the downward revisions to prior months totalled 167,000 for December and January, taking the total change in employed persons well below the implied forecast, and helping the unemployment rate to pop two-ticks to 3.9%. The U6 underemployment rate also rose from 7.2% to 7.3%, while average hourly earnings growth fell to 0.2% m-o-m and average weekly hours worked languished at 34.3, equalling pre-pandemic lows.

Undeterred by the devil in the detail, the algos sprang into action once exchanges opened. Market darling NVIDIA hit a new intraday high of $974 before (presumably) the humans took over and sold the stock down more than 10% to close at $875.28. If our suspicions are correct that it was the AIs buying before the humans started selling (no doubt triggering trailing stops on the way down), the irony is not lost on us.

The 1-day chart for NVIDIA now makes for interesting viewing, because the red candle posted on Friday presents quite a strong bearish engulfing signal. Volume traded on the day was almost double the 15-day simple moving average, and similar price action is observable on the 1-day charts for both Intel and AMD. Regular readers will be aware that we have expressed incredulity in the past about the durability the AI thematic melt-up, so it will be interesting to see whether Friday’s sell off is just a profit-taking blip, or a genuine trend reversal.

AI equities aside, this week ought to be important for markets because the BTFP program expires today. That means that the Fed will no longer be loaning cash to the banking system in exchange for collateral pledged at-par. The KBW Regional Banking index has so far taken this in its stride and is trading 30% above the lows established during the mini banking crisis of this time last year, but the Fed’s liquidity facility was effectively an exercise in can-kicking that makes regional banks a sector of the market worth paying attention to in the weeks ahead. Even here in Sydney, regulators are warning of external risks posed to the banking sector from scheduled refinancing of commercial real estate loans following sharp falls in valuations.

Markets are sending signals in other sectors, too. Gold closed at a new record-high of $2178/oz on Friday after trading above $2200/oz briefly. Gold has been going ballistic since the Friday before last, posting gains even on days where 2-year Treasury yields have risen. Gold bugs are buying as real yields fall from the October highs and inflation breakevens creep higher. This is particularly interesting as gold ETFs have been recording net outflows; suggesting that price gains aren’t being driven by a retail pile-in. Are gold buyers now betting on a stagflationary outcome where the Fed cuts without inflation being anchored at the 2% target? The price action around the US CPI release tomorrow ought to be illuminating.

Leaving the day-to-day movements to one side, we are also seeing further signs of structural change at the macro level. The UK budget last week included a provision for the creation of a British ISA. That is, an Individual Savings Account that provides tax breaks to savers who invest their money in the stock of British companies. This follows moves last year to encourage pension funds to head up the risk curve by allocating 5% of their capital to unlisted investments.

As a Hail Mary option for a government cruising toward an electoral drubbing it’s a curious choice, but it’s worth highlighting as cash-strapped governments increasingly see private savings pools as a funding solution for their spending priorities.

Of course, the UK is not alone in making creeping moves towards financial repression. In contrast to announcements today of increased trade liberalisation, Australian Treasurer Jim Chalmers has in the recent past flagged his interest in tapping private pension savings to fund state spending priorities, including defence, public housing and renewable energy projects. Both the UK and Australia appear intent on finding ways to open up the lungs of their economies, but government wants more say in directing private capital flows for state goals.

So, how far is the blurring of the lines between free markets and state planning likely to go? Given the immense and varied budgetary (and security) pressures that governments are facing, could we see a re-up of WWII-era Victory bonds, where private investors are encouraged to do their patriotic duty by directly financing government at negative real rates?

That would really light a fire under the gold market.

Fauci Deputy Warned Him Against Vaccine Mandates: Email

Authored by Zachary Stieber via The Epoch Times (emphasis ours),

Mandating COVID-19 vaccination was a mistake due to ethical and other concerns, a top government doctor warned Dr. Anthony Fauci after Dr. Fauci promoted mass vaccination.

Coercing or forcing people to take a vaccine can have negative consequences from a biological, sociological, psychological, economical, and ethical standpoint and is not worth the cost even if the vaccine is 100% safe,” Dr. Matthew Memoli, director of the Laboratory of Infectious Diseases clinical studies unit at the U.S. National Institute of Allergy and Infectious Diseases (NIAID), told Dr. Fauci in an email.

“A more prudent approach that considers these issues would be to focus our efforts on those at high risk of severe disease and death, such as the elderly and obese, and do not push vaccination on the young and healthy any further.”

Employing that strategy would help prevent loss of public trust and political capital, Dr. Memoli said.

The email was sent on July 30, 2021, after Dr. Fauci, director of the NIAID, claimed that communities would be safer if more people received one of the COVID-19 vaccines and that mass vaccination would lead to the end of the COVID-19 pandemic.

“We’re on a really good track now to really crush this outbreak, and the more people we get vaccinated, the more assuredness that we’re going to have that we’re going to be able to do that,” Dr. Fauci said on CNN the month prior.

Dr. Memoli, who has studied influenza vaccination for years, disagreed, telling Dr. Fauci that research in the field has indicated yearly shots sometimes drive the evolution of influenza.

Vaccinating people who have not been infected with COVID-19, he said, could potentially impact the evolution of the virus that causes COVID-19 in unexpected ways.

“At best what we are doing with mandated mass vaccination does nothing and the variants emerge evading immunity anyway as they would have without the vaccine,” Dr. Memoli wrote. “At worst it drives evolution of the virus in a way that is different from nature and possibly detrimental, prolonging the pandemic or causing more morbidity and mortality than it should.”

The vaccination strategy was flawed because it relied on a single antigen, introducing immunity that only lasted for a certain period of time, Dr. Memoli said. When the immunity weakened, the virus was given an opportunity to evolve.

Some other experts, including virologist Geert Vanden Bossche, have offered similar views. Others in the scientific community, such as U.S. Centers for Disease Control and Prevention scientists, say vaccination prevents virus evolution, though the agency has acknowledged it doesn’t have records supporting its position.

Other Messages

Dr. Memoli sent the email to Dr. Fauci and two other top NIAID officials, Drs. Hugh Auchincloss and Clifford Lane. The message was first reported by the Wall Street Journal, though the publication did not publish the message. The Epoch Times obtained the email and 199 other pages of Dr. Memoli’s emails through a Freedom of Information Act request. There were no indications that Dr. Fauci ever responded to Dr. Memoli.

Later in 2021, the NIAID’s parent agency, the U.S. National Institutes of Health (NIH), and all other federal government agencies began requiring COVID-19 vaccination, under direction from President Joe Biden.

In other messages, Dr. Memoli said the mandates were unethical and that he was hopeful legal cases brought against the mandates would ultimately let people “make their own healthcare decisions.”

“I am certainly doing everything in my power to influence that,” he wrote on Nov. 2, 2021, to an unknown recipient. Dr. Memoli also disclosed that both he and his wife had applied for exemptions from the mandates imposed by the NIH and his wife’s employer. While her request had been granted, his had not as of yet, Dr. Memoli said. It’s not clear if it ever was.

According to Dr. Memoli, officials had not gone over the bioethics of the mandates. He wrote to the NIH’s Department of Bioethics, pointing out that the protection from the vaccines waned over time, that the shots can cause serious health issues such as myocarditis, or heart inflammation, and that vaccinated people were just as likely to spread COVID-19 as unvaccinated people.

He cited multiple studies in his emails, including one that found a resurgence of COVID-19 cases in a California health care system despite a high rate of vaccination and another that showed transmission rates were similar among the vaccinated and unvaccinated.

Dr. Memoli said he was “particularly interested in the bioethics of a mandate when the vaccine doesn’t have the ability to stop spread of the disease, which is the purpose of the mandate.”

The message led to Dr. Memoli speaking during an NIH event in December 2021, several weeks after he went public with his concerns about mandating vaccines.

“Vaccine mandates should be rare and considered only with a strong justification,” Dr. Memoli said in the debate. He suggested that the justification was not there for COVID-19 vaccines, given their fleeting effectiveness.

Julie Ledgerwood, another NIAID official who also spoke at the event, said that the vaccines were highly effective and that the side effects that had been detected were not significant. She did acknowledge that vaccinated people needed boosters after a period of time.

The NIH, and many other government agencies, removed their mandates in 2023 with the end of the COVID-19 public health emergency.

A request for comment from Dr. Fauci was not returned. Dr. Memoli told The Epoch Times in an email he was “happy to answer any questions you have” but that he needed clearance from the NIAID’s media office. That office then refused to give clearance.

Dr. Jay Bhattacharya, a professor of health policy at Stanford University, said that Dr. Memoli showed bravery when he warned Dr. Fauci against mandates.

“Those mandates have done more to demolish public trust in public health than any single action by public health officials in my professional career, including diminishing public trust in all vaccines.” Dr. Bhattacharya, a frequent critic of the U.S. response to COVID-19, told The Epoch Times via email. “It was risky for Dr. Memoli to speak publicly since he works at the NIH, and the culture of the NIH punishes those who cross powerful scientific bureaucrats like Dr. Fauci or his former boss, Dr. Francis Collins.”
