The search for a truly room-temperature superconducting material has been one of the great Holy Grails in engineering and physics. The ability to move electricity from Point A to B with zero resistance and hence no losses would be a game-changer for human civilization.

Unfortunately, until today, every known superconductor still required very cold temperatures. Today, scientists announced they’ve achieved superconducting at 59 degrees Fahrenheit/15 Celsius. While this is still a bit chilly, you can hit 59F in a well air-conditioned building. This is a genuine breakthrough, but it doesn’t immediately clear the path towards easy deployment of the technology.

At extremely low temperatures, the behavior of electrons through a material changes. At temperatures approaching absolute zero, electrons passing through a material form what are known as Cooper pairs. Normally, single electrons essentially ping-pong through the ionic lattice of the material they are passing through. Each time an electron collides with an ion in the lattice, it loses a tiny amount of energy. This loss is what we call resistance. When cooled to a low enough temperature, electrons behave dramatically differently. Cooper pairs behave like a superfluid, meaning they can flow through material without any underlying energy loss. Tests have demonstrated that current stored inside a superconductor will remain there for as long as the material remains in a superconductive state with zero loss of energy.

There are two problems yet standing between us and a more effective exploitation of this discovery. First, we aren’t sure exactly why this combination of elements works in the first place. The research team used sulfur and carbon, then added hydrogen, forming hydrogen sulfide(H2S) and methane (CH4). These chemicals were placed on a diamond anvil and compressed, then exposed to a green laser for several hours to break sulfur-sulfur bonds. This much is known. Unfortunately, determining the exact composition of the material has proven impossible thus far. The diamond anvil prevents the use of X-rays, and existing technologies that can work around that problem aren’t capable of locating hydrogen atoms in a lattice. The team’s efforts to characterize and understand its own discovery are still ongoing.

It Was His Day Off. Then the Space Station Went for a Spin.
LinkedIn
A new Russian module, named Nauka, suddenly fired its thrusters after docking at the International Space Station on Thursday.

The International Space Station, with a mass of more than 900,000 pounds and spanning an area as large as a football field, is not designed to do back flips like an Olympic gymnast.

But when a newly attached Russian compartment suddenly fired its thrusters on Thursday, NASA said on Twitter that the station tipped by 45 degrees. Actually, it was much more than 45 degrees. “That’s been a little incorrectly reported,” said Zebulon Scoville, the flight director who was in charge at NASA’s mission control center in Houston during Thursday’s tumbling incident. In an interview, Mr. Scoville described how the International Space Station spun one-and-a-half revolutions — about 540 degrees — before coming to a stop upside down. The space station then did a 180-degree forward flip to get back to its original orientation.

The seven astronauts aboard were never in danger, Mr. Scoville said, and the situation did not spiral out of control. Still, in seven years as a NASA flight director, this was the first time that Mr. Scoville had declared a “spacecraft emergency.”

Mr. Scoville was not even scheduled to work on Thursday. Another flight director, Gregory Whitney, led the operations on NASA’s side during the docking of the 23-ton Russian module named Nauka — “science” in Russian.

But Mr. Scoville had led earlier preparations for Nauka’s arrival, and he was curious. “So I decided to put on a tie and just go and watch it from the viewing gallery behind the control room,” he said. “And I was there with Holly Ridings, who’s the chief flight director, and Reid Wiseman, the chief of the astronaut office.”

After the docking, Mr. Whitney had some meetings to attend, so Ms. Ridings asked Mr. Scoville to take over the second half of Mr. Whitney’s shift. “And I’m like, ‘I’d be happy to. The docking — the hard part — is over. Let me go get a handover from him,’” Mr. Scoville said. “And so kind of impromptu, I went in and took the shift from him. He unplugged, I plugged in, and I turned around, and the caution warning board lit up.”

It was 11:34 a.m. Houston time.

“We had two messages — just two lines of code — saying that something was wrong,” Mr. Scoville said.

The messages said the space station had lost “attitude control” — that is, it had begun to tip. Usually, four large, heavy gyroscopes spinning at 6,000 revolutions a minute keep the space station steady, but some force appeared to be overpowering them.

“And so at first I was like, ‘Oh, is this a false indication?’” Mr. Scoville said. “And then I looked up at the video monitors and saw all the ice and thruster firings. This is no kidding. A real event. So let’s get to it. You get about half a breath of ‘Oh, geez, what now?’ and then you kind of push that down and just work the problem.”

Nauka’s thrusters had started firing, trying to pull away from a space station it was securely docked to.

Worse, there was no way to turn them off.

His counterparts at the mission control in Russia told him that Nauka was configured so that it could receive commands directly only from a ground station in Russia. The next pass over Russia was 70 minutes away.

The new Russian module is docked on the underside of the space station. When Nauka tried to move, it pulled down the rear of the space station, and the front pitched upward. “It’s exactly like doing a back flip,” Mr. Scoville said.

The rate of rotation reached a maximum of 0.56 degrees a second, Mr. Scoville said. That spinning is not nearly fast enough to generate significant artificial gravity — he said the astronauts reported almost no noticeable change in conditions within the station.

However, a spinning space station imparts stresses on the structure, and antennas are no longer pointing where they are supposed to. Mission controllers quickly informed the astronauts what was going on and gave them instructions.

“We knew we had a limited amount of time,” Mr. Scoville said.

Declaring a spacecraft emergency activated additional antennas in the United States that could communicate with the space station. But still, the connection between the ground and space was lost twice, once for four minutes, the other time for seven minutes.

Commands from the ground stowed and locked the station’s solar arrays. The astronauts took care of locking down the radiators, which emit heat from the station to space.

Google’s time crystal discovery is so big, we can’t fully comprehend it
LinkedIn
Google corporate office. Google recently found time crystals that can change the computer world

By , BGR

Forget Google Search and Fuchsia. Researchers from Google, Stanford, Princeton, and other universities might have made a computer discovery so big we can’t fully comprehend it yet. Even Google researchers aren’t entirely sure that their time crystal discovery is valid. But if it turns out to be accurate, then Google might be one of the first companies to give the world a crucial technological advancement for the future. Time crystals will be an essential building block in quantum computers, the kind of computers that can solve complex problems with incredible speed and power technologies that aren’t even invented.

What is a quantum computer?
Google isn’t the only company building quantum computers, and these types of machines keep popping up in the news with regularity. Quantum computers won’t reach your phone, and they’re not going to play games. Even if they did, Nintendo will totally ignore the latest computer technology when designing future consoles.

As The Next Web explains, we plan on using quantum computers for challenging problems. Examples include warp drives that could make fast interstellar travel possible. And medical technology that could cure virtually any disease.

But quantum computers are really hard to build, maintain, and even use. That’s where Google’s time crystals might come into play. As it stands now, quantum computers feature qubits, computer bits in the quantum world. These qubits act differently when someone observes them than when they’re left alone. That’s what makes it difficult to measure qubit states. And that instability makes using a quantum computer problematic. That’s where time crystals come in.

Google’s time crystals
Theorized in 2012, the time crystal concept is a new phase of matter. The Next Web explains that time crystals contradict one of Sir Isaac Newton’s famous laws. The first law of motion says that “an object at rest tends to stay at rest and an object in motion tends to stay in motion.”

In our universe, there’s something called high entropy (disorder). Something always happens thanks to energy exchanges. Entropy remains the same if there are no processes but increases in their presence. But that’s not valid for time crystals. They can maintain entropy even when they’re used in a process.

To understand Google’s time crystals, The Next Web offers a great analogy with snowflakes. They have unique designs, as the atoms are arranged in specific ways. Snow falls, melts, water evaporates, and then it’ll eventually become snow again. All these processes involve energy exchanges. A time crystal would be like having a snowflake that can change between two configurations back and forth with no energy usage or energy loss. Time crystals can have their cake and eat it too, and they can do it perpetually.

Visual representation of darker skin is key
LinkedIn

MNT spoke with Dr. Nada Elbuluk, a dermatologist specializing in skin of color, about education, trust, and the underrepresentation of People of Color in research.

Disparities and inequities pervade every area of health, and dermatology is no exception. In fact, insufficient visual representation of conditions that affect darker skin, coupled with many other inequities in healthcare, has led to particularly stark disparities in health outcomes for People of Color.

Although skin cancer tends to affect more non-Hispanic white people than non-Hispanic Black or Asian people, when it does affect People of Color, doctors tend to diagnose it at a much later stage.

For example, doctors diagnose around one-quarter of melanoma cases in African American people when the cancer has already spread to nearby lymph nodes. This is according to the American Academy of Dermatology.

The condition is harder to treat at these later stages, resulting in poorer outcomes for People of Color. The 5-year survival rate for people with skin cancer that has not spread to the lymph nodes is 99%, but this drops to 66% if it does spread.

According to the most recent statistics from the American Cancer Society, white adults in the United States with melanoma have a 5-year survival rate of 92%, while this rate drops to just 67% for African American people.

Systemic discrimination and the bias that the medical community displays toward white skin also mean that white people are twice as likely to see a dermatologist, for example, than Black and Hispanic individuals. This is according to a study from 2018.

Furthermore, the current pandemic has made cancer screenings even more infrequent, which could exacerbate these disparities. For instance, diagnoses of melanoma dropped by more than 67% in 2020 as a result of COVID-19.

In this context, Medical News Today spoke with Dr. Nada Elbuluk — a skin of color expert, practicing dermatologist, and dermatology professor at the Keck School of Medicine at the University of Southern California in Los Angeles — about the causes of health disparities in dermatology and how to remedy them.

We also spoke with Dr. Elbuluk about Project IMPACT. This is a global initiative that she helped launch to reduce racial disparities and bias in dermatology education and medical practice. Dr. Elbuluk is Project IMPACT’s director of clinical impact.

Animals Emerged 350 Million Years Earlier Than Previously Thought, Fossil Discovery Suggests
LinkedIn
A fragment of the spongin skeleton from a modern keratose sponge—literally a bath sponge from Greece.

By George Dvorsky, Gizmodo

Ancient rocks from northwestern Canada have been found to contain structures consistent with sea sponges. At 890 million years old, they could be the oldest known animal fossils on Earth.

Simple, single-celled life forms first appeared on Earth about 3.4 billion years ago, but it took a while for more complex animal life to emerge. The Cambrian Explosion of complex lifeforms happened around 540 million years ago, which coincides with the oldest undisputed sponge fossils on record.

In 2018, the discovery of steroids—a known biomarker—in rocks dated to between 660 million and 635 million years ago pushed the emergence of sponges to the Neoproterozoic, which is at least 100 million years before the Cambrian. Genetic analyses of modern sponges likewise suggests an early origin for these sea creatures, further reinforcing the notion that sponges were the first animals to appear on Earth.

Paco Cardenas, a biologist at Uppsala University in Sweden who wasn’t involved in the new study but is an expert on sponges, said this discrepancy between the fossil record and the chemical and DNA evidence “has been highly debated these past years.” Hence the importance of the newly reported discovery, which has implications for how we understand the origin of all animal life on Earth.

Elizabeth Turner from Laurentian University in Sudbury, Canada, is the sole author of the new Nature paper, and she reports on the discovery of fossil-like structures found in rocks pulled from the 890-million-year-old Little Dal reefs in the Stone Knife Formation of Canada’s Northwest Territories.

“If these fossils are confirmed to be sponge fossils, they would definitely be the first fossils of animals in the fossil record, thus pushing back the emergence of animals to 350 million years before the Cambrian,” Cardenas explained in an email. This recent discovery “may finally reconcile those [previous] lines of evidence,” but it “also raises new questions,” he added.

Peering at the rocks with a microscope, Turner noticed tube-shaped structures covered by mineral calcite crystals. These features bore a striking resemblance to the fibrous skeletons of horny sponges, and they formed from the decay of these ancient creatures, she argues. Horny sponges are still around today, and you might even be using one as a bath sponge (so yeah, humans might actually be descended from bath sponges, and as a dedicated fan of Spongebob Squarepants, I’m actually very cool with that).

Turner was able to rule out other interpretations of the microstructures owing to the configuration of the fossil material.

“It consists of little tubes that branch divergently and then rejoin to form a complex, three-dimensional meshwork,” she said in an email. “Of the branching organisms that could be considered as alternative interpretations, none of them have that kind of three-dimensional meshwork—not true algae, not bacteria, and not fungi.”

50 Years Ago, NASA Put a Car on the Moon
LinkedIn
The lunar rovers of Apollo 15, 16 and 17 parked American automotive culture on the lunar surface, and expanded the scientific range of the missions’ astronaut explorers.

By Rebecca Boyle, New York Times

Dave Scott was not about to pass by an interesting rock without stopping. It was July 31, 1971, and he and Jim Irwin, his fellow Apollo 15 astronaut, were the first people to drive on the moon. After a 6-hour inaugural jaunt in the new lunar rover, the two were heading back to their lander, the Falcon, when Mr. Scott made an unscheduled pit stop.

West of a crater called Rhysling, Mr. Scott scrambled out of the rover and quickly picked up a black lava rock, full of holes formed by escaping gas. Mr. Scott and Mr. Irwin had been trained in geology and knew the specimen, a vesicular rock, would be valuable to scientists on Earth. They also knew that if they asked for permission to stop and get it, clock-watching mission managers would say no. So Mr. Scott made up a story that they stopped the rover because he was fidgeting with his seatbelt. The sample was discovered when the astronauts returned to Earth, Mr. Scott described what he’d done, and “Seatbelt Rock” became one of the most prized geologic finds from Apollo 15.

Like many lunar samples returned to Earth by the final Apollo missions, Seatbelt Rock never would have been collected if the astronauts had not brought a car with them. Apollo 11 and Apollo 13 are the NASA lunar missions that tend to be remembered most vividly. But at the 50th anniversary of Apollo 15, which launched on July 26, 1971, some space enthusiasts, historians and authors are giving the lunar rover its due as one of the most enduring symbols of the American moon exploration program.

Foldable, durable, battery-powered and built by Boeing and General Motors, the vehicle is seen by some as making the last three missions into the crowning achievement of the Apollo era.

“Every mission in the crewed space program, dating back to Alan Shepard’s first flight, had been laying the groundwork for the last three Apollo missions,” said Earl Swift, author of a new book about the lunar rover, “Across the Airless Wilds: The Lunar Rover and the Triumph of the Final Moon Landings.”

“You see NASA take all of that collected wisdom, gleaned over the previous decade in space, and apply it,” Mr. Swift said. “It’s a much more swashbuckling kind of science.”

Once Neil Armstrong’s small step satisfied Project Apollo’s geopolitical goals, NASA emphasized science, said Teasel Muir-Harmony, curator of the Apollo collections at the Smithsonian Institution’s National Air and Space Museum in Washington. While the first moon-walkers retrieved samples near their landing sites, scientists had long hoped for a lunar road trip that promised rare rocks. Plans for a lunar rover were finally given the green light just two months before Armstrong and Buzz Aldrin became the first humans on the moon.

Though moon buggies had been imagined for years, driving a car on the moon is more complicated than it sounds. Throughout the 1960s, engineers studied a variety of concepts: tank-like tracked vehicles, flying cars, even a rotund monstrosity shaped, as Mr. Swift describes it, “like an overgrown Tootsie Pop, with its spherical cabin up top of a single long leg, which in turn was mounted on a caterpillar-tread foot.” Ultimately, a carlike buggy came out on top.

“There were other outlandish ideas, like a pogo stick, or a motorcycle — things that I am glad they didn’t pursue,” Dr. Muir-Harmony said. “The lunar rover is, in some ways, relatively practical.”

The moon car was also quintessentially American. The rover’s exposed chassis, umbrella-like antenna and wire wheels meant it looked like no car on Earth, yet its connection to the American auto industry and the nation’s love affair with the automobile captivated public attention like nothing since Apollo 11, Dr. Muir-Harmony said.

Starting with Project Mercury in the 1960s, a Florida car dealer allowed astronauts to lease Chevrolet cars for $1, which were later sold to the public. The Apollo 15 crew chose red, white and blue Corvettes. A photo spread in Life magazine showed the astronauts posing with their iconic American muscle cars alongside the moon buggy, making the lunar rover look cool by association, Dr. Muir-Harmony said. “There’s a lot to unpack in that picture,” she added.

Scientists Are Using a Balloon to Launch a Telescope
LinkedIn
An image of the Rotten Egg Nebula captured by the Hubble Space Telescope and released by NASA in August 2001.

By Jake Dean, Slate

Exploring space requires scientists to get a little creative. One of my professors at Arizona State University once proposed a mission to smash a copper ball into Mars to examine the ejecta and subsurface of the planet. (ASU is a partner with Slate and New America in Future Tense.) Sometimes, the simplest and cheapest solutions are best in a field where high-tech offerings can pose a significant chance of failure.

Cheap solutions like, say, launching a telescope via a stadium-sized high-tech helium balloon instead of a rocket. That’s the idea behind the Super-Pressure Balloon-borne Imaging Telescope—or SuperBIT, which is expected to make its operational debut in April 2022. On June 21, at the Royal Astronomical Society’s annual National Astronomy Meeting, the team (consisting of scientists from NASA, the Canadian Space Agency, and universities in Canada, the U.S., and England) shared results from testing. This balloon will soon provide telescope imagery to rival (and possibly surpass) that of the Hubble Space Telescope—along with reducing the backlog of imagery requests. As useful as Hubble is, it simply can’t meet the demand of every scientist who wants to task it for a scientific query. It is just one telescope, after all.

So, this telescope isn’t exactly going to space; it will work at an altitude of roughly 25 miles above the surface, according to a Royal Astronomical Society press release. That’s above 99.5 percent of Earth’s atmosphere—so, as you may have recently learned from Bezos and Branson’s childish spat, it’s technically not in space. But unlike Bezos and Branson, it’s actually going to produce useful science. This balloon setup will get the telescope above the atmospheric interference that is critical to ensure good imagery. The atmosphere protects Earth from the harmful effects of various electromagnetic radiation, but it can also blur the images telescopes capture.

Now you may be wondering: How long will this helium balloon stay aloft? We’ve all seen birthday balloons slowly drop to the floor after a few days of clinging to our ceiling. Well, that’s where NASA’s ingenuity comes in. The super-pressure balloon maintains enough internal pressure to stay aloft day or night and should stay airborne for weeks, possibly even months if it needs to. This is quite an improvement when compared with NASA’s past attempt at this design: In late 2014 it planned to keep an Antarctic telescope aloft for 100 days. But the balloon quickly sprung a leak and was forced to land just two days into the mission.

So, given the technical issues NASA has faced in the past, why use a balloon? Three key reasons. First, the cost. The construction and operation budget for the SuperBIT’s first telescope was roughly $5 million, which is insanely cheap by space standards. For context, the Royal Astronomical Society estimated that this is .1 percent of the cost of a similar satellite mission. Second, the ability to bring the balloon back to the surface for repairs and upgrades makes this telescope system uniquely flexible. Given this, the SuperBIT setup isn’t married to one set of hardware forever once launched. As Mohamed Shaaban, a Ph.D. student at the University of Toronto and a central member of the project, explained for Space.com, “SuperBIT can be continually reconfigured and upgraded.” When Hubble becomes obsolete, well, Hubble is no longer useful. And as we recently learned, it’s quite a bother to repair its 1980s technology when it breaks. If a telescope aboard SuperBIT becomes obsolete or runs into technical issues, you just bring the balloon back to the surface and put a new telescope on it. Finally, the use of balloon removes the necessity of burning rocket fuel to launch a telescope. (Rocket fuel is predictably terrible for the environment.)

Lyft ditches Google Maps for Here, partners with Argo AI
LinkedIn
Argo AI's fourth-generation autonomous vehicle, built using the Ford Escape Hybrid.

By , Ars Technica,

The ride-hailing company Lyft is changing up its search data and places provider, which until now have been powered by Google. Lyft will now use Here instead. Lyft says the switch will mean a better search database for places and addresses as well as more accurate predicted arrival times—two important things for a ride-hailing company to get right.

“Over the past six months, we have worked in collaboration with Lyft to implement and test our robust destination catalog that helps riders get to more destinations in cities across North America. Our services are now enriching the Lyft network, spearheading innovation in the rideshare industry,” said Here CEO Edzard Overbeek.

There may be other motivations for the switch. According to Lyft’s head of rideshare, Ashwin Raj, the switch will “improve the efficiency of our marketplace,” but the press release also explicitly mentions keeping user data private.

Lyft also has a new driverless tech partner. In the past, the company has dabbled in developing an in-house capability, but in April, Lyft sold off its internal self-driving division to a subsidiary of Toyota.

Working with external autonomous driving partners seems to be going better, though, as Lyft provides the necessary ride-hailing component to find people to ride in robotaxis being developed by other companies. Lyft worked with Aptiv and Motional in Las Vegas, with plans to launch a robotaxi service using electric Hyundai Ioniq 5s in the city in 2023. And Lyft has helped Waymo begin actual commercial operations in Arizona.

Humans, Neanderthals share up to 98.5 percent DNA, new study reveals
LinkedIn
Many humans DNA carry genes from Neanderthals, a legacy of past admixture

You’re not much different than a Neanderthal, according to your DNA. At least according to a new study published by Science Advances. The journal found that as little as 1.5 percent of our DNA is unique to modern humans, and not shared with our ancestral species.

“That’s a pretty small percentage,” Nathan Schaefer, a University of California scholar and co-author of the report, told The Associated Press. “This kind of finding is why scientists are turning away from thinking that we human are so vastly different from Neanderthals.”

The study compared modern human DNA to that extracted from the fossilized remains of extinct Neanderthals and Denisovans, two pre-human species that died off 35,000 and 50,000 years ago, respectively. Both species are believed to have bred with early humans.

“Many humans carry genes from Neanderthals, a legacy of past admixture,” the study states. “We find that only 1.5 to 7 percent of the modern human genome is uniquely human.”

Tech Education Financing for Black Communities
LinkedIn
diverse students looking at computer screen in a college classroom environment

There are two ways of learning tech skills – one approach is the use of free courses, guides and other online resources and the second is by enrolling in schools that offer tech programs and education.

According to Brookings, members of the black and hispanic communities are still underrepresented in the tech sector despite increasing numbers. This means that if you want the numbers to continue to change, you’ll have to step up to the challenge.

If you do decide to learn tech skills alone, you won’t get a degree or a certificate, but this very much still a viable option to get your foot in the door. Know that employers are willing to hire someone without a tech degree if you can prove your worth but getting a diploma, certificate or degree can greatly boost your chance of being hired.

If acquiring certification is the path you’re willing to take, consider enrolling in a course hosted by reputable education companies. Know that tech education can be expensive, up to $25,000 even for certificates, but it is worth it. These schools often offer financing options and post-graduation employment support benefits.

With that in mind, here some aspects we should consider in order to get financing for tech education.

Apply for ‘Academy’ Organization Jobs

Tech skills are highly demanded these days, and employers know it. For that reason, if you are already in the tech field and you want to get additional education, you can get it by applying for jobs where companies can pay for your professional growth.

By doing so, you will be able to update your skills to stay current. An excellent example is Google. The company helps its employees get the education they need to take the company to the next level. Google invests vast amounts of money in new technologies like machine learning to provide better services and develop better products for customers.

So, if you are looking to learn machine learning skills, you should consider applying for Google’s vacancies. At Google, you will not only be able to learn new skills but also will be able to earn a good salary and have great benefits.

There are also companies like Facebook that are investing huge amounts of money in web development as they know that websites are revolutionizing the market. In effect, websites are increasing company brand recognition as well as customers’ reach. Through websites, companies can interact with customers all around the world. For that reason, eCommerce is playing a pivotal role in digital marketing. Also, websites help companies to collect valuable data to set new standards and meet new customers’ requirements. Given these points, doubtlessly web development skills are required these days, and for that reason, Facebook is willing to invest money in its employees’ education.

Enroll in Coding Bootcamps with Scholarship Opportunities

Some educational companies think about the future. In effect, they want their tech aspirants to prepare for next world challenges. For that reason, as getting an education can be expensive, they offer several financing options for students who want to join their programs. With this in mind, Flatiron is a company that provides scholarships to students. With the program, students can receive up to $1,500 per month to pay for tuition. The company offers several programs in software engineering, full-stack development, data science, and other in-demand subjects. Also, the company is committed to students’ success, and for that reason, they receive help from a support career team that allows students to receive help from experts in the field.

In like manner, Thinkful is a company that thinks of its students. For that reason, they also offer financing options to students to help them cover education costs. It is vital to mention that the company offers a tuition guarantee to students. Given that, students will receive their money back if they don’t get a qualifying job within six months after program completion. Also, Thinkful offers other financing options that include living stipends, income-share agreements, and discounts to help reduce students’ financial stress.

As can be seen, there is no doubt that if you want to change careers or you want to start a new tech career joining Thinkful’s team is the right option to take.

NASA predicts a “wobble” in the moon’s orbit may lead to record flooding on Earth
LinkedIn
moon in space

By Sophie Lewis, CBS News

Every coast in the U.S. is facing rapidly increasing high tide floods thanks to a “wobble” in the moon’s orbit working in tandem with climate change-fueled rising sea levels. A new study from NASA and the University of Hawaii, published recently in the journal Nature Climate Change, warns that upcoming changes in the moon’s orbit could lead to record flooding on Earth in the next decade. Through mapping the National Oceanic and Atmospheric Administration’s (NOAA) sea-level rise scenarios, flooding thresholds and astronomical cycles, researchers found flooding in American coastal cities could be several multiples worse in the 2030s, when the next moon “wobble” is expected to begin. They expect the flooding to significantly damage infrastructure and displace communities.

While the study highlights the dire situation facing coastal cities, the lunar wobble is actually a natural occurrence, first reported in 1728. The moon’s orbit is responsible for periods of both higher and lower tides about every 18.6 years, and they aren’t dangerous in their own right.

“In half of the Moon’s 18.6-year cycle, Earth’s regular daily tides are suppressed: High tides are lower than normal, and low tides are higher than normal,” NASA explains. “In the other half of the cycle, tides are amplified: High tides get higher, and low tides get lower. Global sea-level rise pushes high tides in only one direction – higher. So half of the 18.6-year lunar cycle counteracts the effect of sea-level rise on high tides, and the other half increases the effect.”

But this time around, scientists are more concerned. With sea-level rise due to climate change, the next high tide floods are expected to be more intense and more frequent than ever before, exacerbating already grim predictions.

In 2019, NOAA reported more than 600 such floods. Scientists expect three to four times that amount in the mid-2030s, after sea-level rise has another decade to progress.

According to the study, these floods will exceed flooding thresholds around the country more often, and can also occur in clusters lasting more than a month, depending on the positions of the moon, Earth and sun. During certain alignments, floods could happen as frequently as every day or every other day.

“Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse,” said NASA Administrator Bill Nelson. “The combination of the Moon’s gravitational pull, rising sea levels, and climate change will continue to exacerbate coastal flooding on our coastlines and across the world.”
