Why Native American children have higher rates of disability

The rates of disability among U.S. children are increasing, with the highest rate of disability among Native American children, according to a newly released brief by the U.S. Census Bureau.

More than 3 million children in the U.S. had a disability in 2019, slightly up from data collected more than a decade ago.

But a disproportionate number of Native American children (5.9%) had a disability, followed by children of more than one race (5.2%) and Black children (5.1%). Household income also appeared to play a role, with 6.5% of children living below the poverty line having a disability, as compared to 3.8% of children living in families with incomes above the poverty threshold.

"There are decades of evidence that these particular racial and ethnic groups, especially American Indian, Native American groups and Black Americans, have poor access to care, and also may not have access to the same quality of health care services," said Dr. Regan Bergmark, an otolaryngologist at Boston's Brigham and Women's Hospital with an interest in addressing health care disparities.

Bergmark said screening programs can be an important first step in identifying disabilities that may benefit from early intervention and treatment. A disability includes problems with seeing or hearing, thinking, walking and other disabilities that affect day-to-day living. But these conditions also negatively impact a child's future employment and socialization.

A lack of access to high-quality care can be a major contributor to the higher rates of disability. Native American children and their families have historically had inadequate prenatal care, higher rates of premature birth and exposure to environmental stressors. Some live in rural or remote communities where they may experience difficulty with transportation to appointments and higher wait times. Finding primary care providers and pediatricians who understand the unique cultural needs of these children can also pose a challenge.

For example, some children might benefit from therapy that incorporates their tribes' historical connection to horses.

"In many tribes, horses are connected to the land and to ceremony, and using them to help children with walking, with emotional and social therapy and even mental health therapy has been really effective," said Dr. Shaquita Bell, a pediatrician at Odessa Brown Children's Clinic in Seattle and past chair of the Committee on Native American Child Health, in describing how culturally sensitive therapies can benefit children.

The Indian Health Service, an agency within the U.S. Department of Health and Human Services, aims to promote health at local, regional and national levels for members of more than 500 federally recognized American Indian and Alaska Native tribes and their descendants. However, the IHS remains underfunded, limiting the services it can provide, according to Bell and Bergmark.MORE: To Native Americans, reparations can vary from having sovereignty to just being heard

Experts say that it's important for doctors and other health care providers to learn as much as they can about Native American history and customs, so they can provide culturally competent care.

"You are probably caring for native children; your kids are probably going to school with them; you're probably grocery shopping with folks, so awareness ... of the unique needs of American Indian and Alaskan Native children are really important so that we can help them achieve their health goals," Bell emphasized.

Mining executives warn Ottawa about dependence on China for strategic minerals amid deteriorating relations

4/5/2021

OTTAWA — Mining executives and national security experts are warning the federal government about China’s domination of strategic mineral supplies, saying Ottawa needs to better protect supply chains for modern technology that relies on them like electric vehicles and smart phones.

© Provided by National Post Pierre Gratton, head of the Mining Association of Canada, is urging federal policymakers to create a framework to develop and then protect Canadian supply chains for batteries and other products, and recommended the federal government establish a $250-million program over five years to incentivize investment in demonstration projects.

In testimony before the House of Commons natural resources committee this month, experts described China’s decades-long efforts to control the market for critical minerals — including the 17 rare earth elements — by rapidly expanding its processing capacity or by acquiring foreign assets to dominate supply chains. The minerals, which include magnesium, lithium and scandium, are used to develop such strategic products as solar panels, wind turbines, electric car batteries, mobile phone components and guided missiles.

Canada sits atop an abundance of such minerals, from a large deposit of neodymium in northern Saskatchewan (used in the manufacture of magnets) to the sizeable pockets of lithium found in Quebec. That strategic advantage, experts said, makes it incumbent on Ottawa to help strengthen Canada’s supply chain and protect against China’s coercive foreign policy tactics.

The witnesses are sounding the alarm as Canada-China relations deteriorate over the detention of Canadians Michael Kovrig and Michael Spavor. The impasse has revealed China’s willingness to inflict economic pain by restricting Canadian exports.

Robert Fung, chairman of Canadian mining firm Torngat Metals, said China has over the years amassed around 80 per cent of global processing capacity for strategic minerals, and has used that position to manipulate prices as a way to punish competitors.

“We all know that is not a geopolitically acceptable situation,” he said in testimony earlier this month.

Fung and others stressed that Canada’s abundance of natural deposits of minerals like lithium, nickel and others could give Canada a significant strategic edge in coming years. Minerals used in the manufacture of magnets for electric cars, for example, are almost exclusively located in Canada and in Australia, which has already taken the lead over Canada in their development.

“This is a once-in-a-lifetime shot at being in a position to have a degree of control in a very large market,” Fung said.

Pierre Gratton, head of the Mining Association of Canada, described an “increasingly uncomfortable reliance” on China for commodities, particularly for rare earths and other critical minerals. He said China declines to “play by our rules” in the development of those minerals, effectively undercutting the free market.

“For decades, China has held monopoly-like control over critical minerals production and distribution, rendering the rest of the world reliant on procurement and creating a level of risk that deters investors from entering these markets,” he said.

Gratton urged policymakers to create a framework to develop and then protect Canadian supply chains for batteries and other products, and recommended the federal government establish a $250-million program over five years to incentivize investment in demonstration projects.

“If we can get to it and create the right conditions, we could be in a very, very strong place going forward.”

Industry Minister François-Philippe Champagne last week updated the federal government’s foreign takeover guidelines involving rare earths and critical minerals, effectively lowering the threshold for what would trigger a national security review.

Earlier this month, Natural Resources Canada released a list of 31 minerals now designated as strategic, everything from copper to cobalt to tellurium.

Ottawa more broadly has faced criticism for failing to set out clear national security thresholds to guide proposed takeovers of Canadian natural resource assets, including by state-owned Chinese enterprises.

Those criticisms effectively prompted Ottawa last year to bring “enhanced scrutiny” to proposed takeovers from Chinese and other firms. In December, the Industry Department rejected the proposed $207-million takeover of TMAC Resources, a small company developing an Arctic gold mine, by Shandong Gold Mining, a Chinese state-owned enterprise.

Committee witnesses also warned that competition to secure critical minerals will only intensify as demand for electric vehicles and electronics grows.

Simon Moores, managing director of Benchmark Mineral Intelligence, said China is likely to possess 67 per cent of global capacity to build lithium-ion batteries by 2030, due in large part to significant investments the country has made, including in so-called “mega factories.” North America, by comparison, will have just 12 per cent of the market, according to BMI research.

“We are in the midst of a global battery arms race, where the world’s major economies are building a base to the energy storage revolution,” Moores said.

But developing strategic assets in Canada has proved challenging. Jamie Deith, chief executive of mining firm Eagle Graphite, described to the committee the struggles he has had raising capital to develop his graphite quarry in British Columbia, largely due to China’s stranglehold on the market.

China in the past has flooded markets with supply as a way to lower prices, making it less economically feasible for competitors to develop rare minerals.

“Natural graphite is the poster child for minerals dominated by China and, in the face of a near monopoly wielded by one of the most powerful governments in the world, no combination of attributes could convince prospective sources of capital to invest in required expansion,” Deith said. “Supply chains around the world seemed mostly content with heavy reliance on a single nation.”

The Chinese government has also restricted output in order to hike prices or to cut off foreign countries from strategic supply. China in 2010 cut Japan’s supply of rare earths in response to a dispute over the Diayou Islands, restricting its ability to manufacture hybrid cars and other products.

Witnesses pressed Ottawa to release a national strategy on the development of critical minerals and to deepen ties with Europe, the U.S. and Japan to strengthen its non-Chinese supply chains.

Nancy Concepcion, an executive manager at Vale Canada, proposed that government work with industry to develop “battery hubs” as a way to ensure Canada has a piece of the market through the entire supply chain.

“We will definitely have to expand. Not only do we need to promote the auto industries into making EVs, which means promoting them with consumers, but we also have to support the development of that supply chain,” she said. “The processing of the minerals, the development of the battery cells, the battery materials, all need to be brought together and incentivized.”

'Allergic reaction to US religious right' fueling decline of religion, experts say

Fewer than half of Americans belong to a house of worship, a new study shows, but religion – and Christianity in particular – continues to have an outsize influence in US politics, especially because it is declining faster among Democrats than Republicans.

Just 47% of the US population are members of a church, mosque or synagogue, according to a survey by Gallup, down from 70% two decades ago – in part a result of millennials turning away from religion but also, experts say, a reaction to the swirling mix of rightwing politics and Christianity pursued by the Republican party.

The evidence comes as Republicans in some states have pursued extreme “Christian nationalist” policies, attempting to force their version of Christianity on an increasingly uninterested public.

This week the governor of Arkansas signed a law allowing doctors to refuse to treat LGBTQ people on religious grounds, and other states are exploring similar legislation.

Gallup began asking Americans about their church membership in 1937 – and for decades the number was always above 70%. That began to change in 2000, and the number has steadily dropped ever since.

Some of the decline is attributable to changing generations, with about 66% of people born before 1946 are still members of a church, compared to just 36% of millennials.

Among other groups Gallup reported, the decline in church membership stands out among self-identified Democrats and independents. The number of Democratic church members dropped by 25% over the 20 year period, with independents decreasing by 18%. Republican church members declined too, but only by 12%.

David Campbell, professor and chair of the University of Notre Dame’s political science department and co-author of American Grace: How Religion Divides and Unites Us, said a reason for the decline among those groups is political – an “allergic reaction to the religious right”.

“Many Americans – especially young people – see religion as bound up with political conservatism, and the Republican party specifically,” Campbell said.

“Since that is not their party, or their politics, they do not want to identify as being religious. Young people are especially allergic to the perception that many – but by no means all – American religions are hostile to LGBTQ rights.”

Research by Campbell shows that a growing number of Americans have turned away from religion as politicians – particularly Republicans – have mixed religion with their politics. Campbell says there has always been an ebb and flow in American adherence to religion, but he thinks the current decline is likely to continue.

“I see no sign that the religious right, and Christian nationalism, is fading. Which in turn suggests that the allergic reaction will continue to be seen – and thus more and more Americans will turn away from religion,” he said.

The number of people who identify as non-religious has grown steadily in recent decades, according to Michele Margolis, associate professor of political science at the University of Pennsylvania and author of From Politics to the Pews. More than 20% of all Americans are classed as “nones”, Margolis said, and more than a third of Americans under 30.

“That means non-identification is going to continue becoming a larger share of population over time as cohort replacement continues to occur,” Margolis said. But she agreed another factor is the rightwing’s infusion of politics with theism.

“As religion has been closed linked with conservative politics, we’ve had Democrats opting out of organized religion, or being less involved, and Republicans opting in,” she said.

Christian nationalists – who believe America was established as, and should remain, a Christian country – have pushed a range of measures to thrust their version of religion into American life.

You virtually have to wear religion on your sleeve in order to be electedAnnie Laurie Gaylor

In states including Louisiana, Arkansas and Florida, Republicans have introduced legislation which would variously hack away at LGTBQ rights, reproductive rights, challenge the ability of couples to adopt children, and see religion forced into classrooms.

The governor of Arkansas recently signed into law a bill that allows medical workers to refuse to treat LGBTQ people on religious grounds. Montana is set to pass a law which would allow people or businesses to discriminate, based on religion, against the LGBTQ community.

“Do not make me NOT do what my God tells me I have to do,” said Republican Montana congressman John Fuller, a supporter of the law.

Alison Gill, vice-president for legal and policy at American Atheists, who authored a report into the creep of Christian extremism in the US, warned that the drop-off in religious adherence in America could actually accelerate that effort, rather than slow it down.

“Surveys of those who identify with Christian nationalist beliefs consistently show that this group feels that they are subject to more discrimination and marginalization than any other group in society, including Islamic people, Black people, atheists, [and] Jewish people,” Gill said.

“They are experiencing their loss of prominence in American culture as an unacceptable attack on their beliefs -- and this is driving much of the efforts we are seeing to cling onto power, undermine democracy, and fight for ‘religious freedom’ protections that apply only to them.”

The influence of religion over politics is stark, Gill said.

“America perceives itself to be a predominantly religious society, even if the facts no longer agree. Politicians often feel beholden to pronounce their religious faith – and are attacked for a perceived lack of it,” she said.

While the danger of a right-wing backlash is real, Annie Laurie Gaylor, co-founder of the Freedom From Religion Foundation, said that the Gallup data suggests the US is moving in a positive direction.

“We have this constitutional separation of church and state in America, and our constitution is godless, and it says you can’t have a religious test for public office, and yet you virtually have to wear religion on your sleeve in order to be elected,” Gaylor said.

“There is movement [away from religion], and we’re just delighted to see this. We think it’s great that Americans are finally waking up.”

Satellite images show large Russian military build up in Arctic: report

THEY HAVE A FLOATING NUKE POWER PLANT

Russia is building up military equipment in the Arctic and testing new weapons there as it looks to assert dominance of the region, CNN reported.

Russia is building upon military bases, hardware and underground storage facilities on its Arctic coastline, with bombers, MiG31BM jets and new radar systems close to the Alaskan coast, according to satellite images provided to CNN by space technology company Maxar.

Included in the buildup is the Poseidon 2M39 unmanned stealth torpedo, a so-called super-weapon powered by a nuclear reactor. Russia is quickly developing the armament and tested it in February, with further tests planned this year, according to Russian state media.

Moscow intends for the torpedo to be able to elude U.S. and NATO coastal defenses and is "part of the new type of nuclear deterrent weapons," the head of Norwegian intelligence, Vice Admiral Nils Andreas Stensønes, told CNN.

To counter the buildup, NATO and the U.S. have also moved equipment into the area in the past year, including the U.S. military's stealth Seawolf submarine as well as its B-1 Lancer bombers, which recently flew over the eastern Barents Sea.

"There's clearly a military challenge from the Russians in the Arctic," a senior State Department official told CNN. "That has implications for the United States and its allies, not least because it creates the capacity to project power up to the North Atlantic."

While the increase of Russian military assets has taken place inside Russian territory, U.S. officials are worried Moscow may move use its forces to take over areas of the Arctic outside its borders.

The buildup has been all the more apparent in recent days with Russia holding military flights near Alaskan airspace and submarine activity in the Arctic.

In late March, three Russian nuclear ballistic missile submarines simultaneously broke through several feet of ice in the Arctic in a military drill. And last week, Russia flew jets and bombers near Alaskan airspace, including 10 times on Monday alone.

"I think we've been very clear about the threats that we see from Russia across domains. ... We're taking them very, very seriously," Pentagon press secretary John Kirby said last week.

In addition, Moscow is regularly testing high-tech weapons, including the Poseidon 2M39 and the "Tsirkon" anti-ship hypersonic cruise missile.

Russia also is attempting to influence a shipping lane that runs from between Norway and Alaska known as the "Northern Sea Route." The route cuts in half shipping times to move containers from Europe to Asia.

Amazon illegally fired 2 activist employees, labor board reportedly finds

Amazon illegally fired two employees who had criticized it, the National Labor Relations Board found.

The employees had complained about working conditions and the company's impact on climate change.

Amazon maintains that the employees were fired for violating internal policies.

Amazon acted illegally by firing two employees who publicly criticized it last year, the National Labor Relations Board found, The New York Times reported on Monday.

Emily Cunningham and Maren Costa were fired in April 2020 after discussing their concerns about the company's impact on climate change and its treatment of warehouse workers during the pandemic. At the time, Amazon said they had violated internal policies.

The NLRB, an independent federal agency to protect the rights of private-sector employees in the US, said it would accuse Amazon of unfair labor practices if Amazon did not settle the case with the women, Cunningham told The Times.

Cunningham told the publication that the agency's finding was a "moral victory" that "really shows that we are on the right side of history and the right side of the law."

Amazon again denied that the women were fired for criticizing the company publicly, repeating its statement that they had violated internal policies.

"We support every employee's right to criticize their employer's working conditions, but that does not come with blanket immunity against our internal policies, all of which are lawful," Jaci Anderson, an Amazon spokesperson, told The Times.

"We terminated these employees not for talking publicly about working conditions, safety or sustainability but, rather, for repeatedly violating internal policies," she added.

NLRB complaints about Amazon have more than tripled in the past year, NBC News reported last week. Since the beginning of the COVID-19 pandemic, at least 37 complaints have accused Amazon of infringing on workers' rights to organize, the report said.

Last month, the NLRB accused Amazon of illegally intimidating and threatening a worker in New York City who led a walkout in March 2020.

The nearly 6,000 employees at an Amazon warehouse in Birmingham, Alabama, voted last week on whether to form the firm's first union. The employees have said the vote was prompted by difficult working conditions, long hours, and a lack of job security.

Amazon has publicly opposed the campaign from the beginning with anti-union ads and signs.

The news rounds out a tough week for Amazon, which apologized on Friday for snarky tweets targeted at Rep. Mark Pocan that denied that its workers peed in bottles. After the firm's original tweets, Amazon drivers told journalists - including at Insider - that time pressure meant they peed in bottles, pooped in bags, and struggled to change menstrual pads in their vans.

Representatives for Amazon and the NLRB did not immediately respond to Business Insider's request for comment.

Scientists Discover Weird 'Falgae' in Cornwall That Are Genetically Unique

David Nield 

4/5/2021


The mesmerizing red algal species Phymatolithon calcareum clumps together to form habitats called maerl beds in coastal regions across the northeast Atlantic, but researchers have discovered a pocket of the algae near Cornwall in the UK that's genetically distinct from the rest of the region.

It's been dubbed 'falgae', likely because of its location in the Fal Estuary – a busy waterway used by both commercial and naval ships sailing to and from Falmouth port.

These maerl beds are important habitats for many marine species – like coral reefs – and play an important role in the storage of carbon. The researchers are hoping that the new findings will help in efforts to protect these beds from numerous threats.

"It appears that the unique diversity in the Fal Estuary has likely been shaped over time by geographical isolation of this maerl bed and a lack of genetic exchange with other P. calcareum populations," says marine biologist Tom Jenkins, from the University of Exeter in the UK.

Even the algae at the Manacles reef, just 13 kilometers (8 miles) away, across Falmouth Bay, have a different genetic make-up, the team found. They used a whole-genome genotyping process to study the DNA from 12 separate maerl bed sites stretching from Norway to Portugal.

Genetic variations could be found in different geographical spots, but it was only the Fal Estuary sample that was completely genetically distinct – and it doesn't appear to be a hybrid of other types of algae either, at least based on the samples the research team used.

The researchers suggest that it's the isolation of this batch of red algae that has caused it to be genetically distinct. Algae that form maerl beds grow very slowly, even over thousands of years, and aren't easily dispersed.

"The wider genetic differences we found across north-east Atlantic are probably explained by the low dispersal capacity of this species, which limits connectivity between particular populations separated by large distances," says Jenkins.

Maerl beds can provide safe harbor for thousands of fish and invertebrates, but their existence is threatened by climate change, the dredging required to maintain waterways, and the shipping traffic that travels to and from ports.

The danger from marine pollution is a particular problem for the algae in the Fal Estuary because it is so busy. In many ways, the day-to-day activity on waterways is at odds with the conditions maerl beds need to survive.

Knowing more about the genetics of these maerl beds should help preserve them, the team behind the new study says: knowing how these batches of red algae are different is going to be important for conservation efforts.

"There are several large maerl beds around the coast of south and southwest England, and the genetic differences we identified show that these need to be managed on a site-by-site basis, as separate and distinct populations," says evolutionary biologist Jamie Stevens, from the University of Exeter.

The research has been published in Evolutionary Applications.

Japan just recorded its earliest cherry blossom bloom in 1,200 years. scientists warn it's a symptom of the larger climate crisis

By Jessie Yeung, Selina Wang and Derek Van Dam, CNN 

4/5/2021

Think of Japan in the spring, and the image that comes to mind is likely the country's famous cherry blossoms, also known as "sakura" -- white and pink flowers, bursting across cities and mountains, petals covering the ground.

The flowers, which experience a "peak bloom" that only lasts a few days, have been revered in Japan for more than a thousand years. Crowds celebrate with viewing parties, flocking to the most popular locations to take photos and have picnics underneath the branches.

But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record -- and scientists warn it's a symptom of the larger climate crisis threatening ecosystems everywhere.

Yasuyuki Aono, a researcher at Osaka Prefecture University, has gathered records from Kyoto back to 812 AD from historical documents and diaries. In the central city of Kyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said.

And in the capital Tokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.

"As global temperatures warm, the last spring frosts are occurring earlier and flowering is occurring sooner," said Dr. Lewis Ziska from Columbia Universities Environmental Health Sciences.

The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. In Kyoto, the peak date hovered around mid-April for centuries, according to Aono's data, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.

"Sakura blooms are very temperature sensitive," said Aono. "Flowering and full bloom could be earlier or later depending on the temperature alone," he said. "The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius (6.3 degrees Fahrenheit) to this day."

This year's seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm, so "the buds are completely awake after enough rest."

Their early bloom, however, is just the tip of the iceberg of a worldwide phenomenon that could destabilize natural systems and countries' economies, said Amos Tai, assistant professor of earth science at the Chinese University of Hong Kong.

There are two sources of increased heat, which is the main factor making the flowers bloom earlier: urbanization and climate change. With increased urbanization, cities tend to get warmer than the surrounding rural area, in what is called the heat island effect. But a bigger reason is climate change, which has caused rising temperatures across the region and the world.

And these earlier dates aren't just a matter of tourists scrambling to catch peak bloom before the petals all fall -- it could have a lasting impact on entire ecosystems, and threaten the survival of many species.

For every action there is a reaction

Plants and insects rely heavily on each other, and both use environmental cues to "regulate the timing of different stages of their life cycles," said Tai. For instance, plants sense the temperature around them and if it's warm enough for a consistent period, they start to flower and their leaves start to emerge. Similarly, insects and other animals depend on temperature for their life cycles, meaning higher heat can cause faster growth.

"The relationship between plants and insects and other organisms have developed over many years -- thousands to millions of years," said Tai. "But in the recent century, climate change is really wrecking everything and perturbing all of these relationships."

Different plants and insects may respond to the rise in heat at different paces, throwing their life cycles out of sync. Whereas they once timed their growth simultaneously each spring, now flowers may bloom before insects are ready, and vice versa -- meaning "the insects may not find enough food to eat from the plants, and the plants don't have enough pollinators (to reproduce)," he said.

Over the past decade, some plant and animal populations have already begun shifting to both "higher altitudes" and "higher latitudes" to escape the effects of climate change, according to a 2009 study in Biological Conservation. But it's becoming harder for ecosystems to adapt, with climate change making the weather more and more unpredictable. Though the trend of flowering dates is generally moving earlier, unexpected and extreme weather means that there is still huge variability year-by-year.

"Ecosystems are not accustomed to these kinds of large fluctuations, it causes them a lot of stress," said Tai. "Productivity may be reduced, and ecosystems may even collapse in the future."

Not limited to cherry blossoms

This year's change in flowering dates isn't limited to just Japan; the cherry blossoms that adorn the Tidal Basin in Washington, DC, have also bloomed early. According to the National Park Service, the peak bloom date of the Washington cherry blossoms has advanced forward by nearly a week from April 5th to March 31.

And the effects of climate change aren't just limited to cherry blossoms."Cherry blossoms catch the eye, people love to go see them, but lots of other plants are experiencing changes in their life cycle as well, and may have even stronger influence on the stability of their ecosystems," said Tai.

The same phenomenon is already happening to many crops and economically valuable plants, he said -- posing big problems for food security and farmers' livelihoods. Food supplies in some of the most vulnerable regions in the world are being directly affected by droughts, crop failures and locust swarms.

In some regions, farmers may be forced to change the types of crops they grow. Some climates will become too hot for what they are growing now, while other climates will see more flooding, more snow, more moisture in the air, which will also limit what can be grown.

"(Farmers) have a much harder time predicting when they will have a good year, when they will have a bad year," Tai added. "Agriculture now is more like a gamble, because climate change is randomizing the things happening in our ecological systems."

THAT MIGHT NOT BE SUCH A GOOD IDEA
Elon Musk Could Help Aliens Notice Humans, Study Says
Caroline Delbert 

POPMECH

4/4/2021

Earth could eventually be visible to aliens because of the signature left by Starlink satellites.

Scientists say this will take about 1,000 years.

This research could also help scientists tune our telescopes to better see aliens.

Elon Musk has a grand goal for SpaceX’s Starlink: use an eventual 40,000 satellites to blanket the entire planet in internet coverage, far surpassing any existing satellite internet service. But there may be more to the mission. In a new study, one scientist suggests Musk’s satellite network may also make Earth a major target of alien interest.

➡ You think space is bad***. So do we. Let’s nerd out over it together.

Starlink’s 40,000 satellites in orbit—1,000 of which astronomers have already criticized for obstructing the night sky—will be enough to register as a megastructure that will eventually appear on some faraway civilization’s radar, writes Zaza Osmanov, a professor of astrophysics at the Free University of Tbilisi in Georgia, in a new paper published to the preprint server arXiv.

Osmanov studied how the electrical signature of Starlink will show up via signals to large interferometers in distant alien civilizations. Since Earth’s advanced interferometers would be able to detect this activity from other planets, Osmanov writes, anyone else with the same technology could do the same back to us.

“We consider the possible observational characteristics of a planetary megastructure partially or completely covering an Earth-like planet located in the habitable zone,” Osmanov explains. That means finding the key inflection point at which the Starlink satellite network would become detectable to a faraway observer.

To assess what’s visible from where, Osmanov explored what it would mean to cover Earth with a large amount of literally anything. Is there enough graphene, for example, to blanket the atmosphere and become visible from deep space? It turns out there’s enough carbon available to us to do this many, many times over if we wanted—like an Everlasting Gobstopper of Earth-size graphene layers.

How much time will we need to launch and place that much material, now that we know we have it? Osmanov estimates this will take 1,000 years of launches at regular intervals. At that point, enough material would be in space for humans to become visible to aliens.

And what about Starlink? Musk doesn’t have plans to make a material blanket as part of his satellite network—this would block the sun, and not in the hip Bill Gates way. If people are mad about thousands of tiny satellites, imagine how a giant sky blanket would go over. But the radio signals thrown off by Starlink and other satellites mean the right instrument on a faraway planet could observe the satellite network’s energy and wave signature.

There’s even a third option, speaking of the Gates-funded geoengineering. If Earthlings decide to fill the stratosphere with aerosol particles as a way to reflect away warming solar radiation, it’s feasible to wonder if that level of reflection would be visible as some kind of iridescent shimmer. Will Earth light up like an iconic color-changing‘90s Ford Explorer?

For now, Earth is safely invisible to the faraway telescopes and instruments of any aliens scanning the skies with comparable technology to our own. Of course, that presumes that they’re not already watching us.

430,000 YEARS AGO
Particles were produced when a meteorite EXPLODED in mid-air

Ryan Morrison For Mailonline 

4/1/22021

An ancient meteorite that exploded in mid-air 430,000 years ago left behind unusual particles of matter in the mountains of Antarctica, a new study reveals.

An international team of space scientists, led by the University of Kent, examined 'extra-terrestrial particles' recovered from the summit of mountain Walnumfjellet in the Sør Rondane Mountains of Queen Maud Land, Antarctica.

The pieces of vaporised space rock were deposited after a 330ft asteroid exploded close to the frozen surface of Antarctica hundreds of thousands of years ago.

The findings may help scientists identify past 'airburst' impacts and prepare for future ones, which could wreak severe destruction if they happened in densely populated locations.

IMPACT EVENT: SPACE ROCK EXPLOSIONS RELEASING IMMENSE ENERGY


An impact event is when a space rock collides with the Earth, or explodes in its upper or lower atmosphere.

There can be significant consequences from a crater forming impact.

Including the Chicxulub event 66 million years ago that killed dinosaurs.

The Tunguska event was a massive explosion in Russia in 1908 over a sparsely populated area of Siberia.

It flattened 80 million trees, but left behind no impact crater.

It is thought it disintegrated six miles above the surface.


Large airbursts, which occur when asteroids enter Earth's atmosphere and explode in mid-air, are estimated to occur far more frequently than crater-forming impacts.

However, due to the challenges of identifying and characterising the far-flung residues of exploded meteorites, large airbursts are mostly identified through eyewitness accounts rather than by evidence in the geological record.

To piece together the puzzle of a possible ancient meteorite event that struck Antarctica while barely leaving a trace, study authors looked to tiny particles.

Matthias Van Ginneken and colleagues used microscopy and laser techniques to analyse 17 black, spherical igneous particles gathered from Walnumfjellet.

They determined that the particles, which were mostly between about 100 and 300 micrometers in size, were mainly composed of the minerals olivine and iron spinel, welded together by small amounts of glass.

The chemistry of these particles, including their high nickel content, suggests they originated in outer space.

They also compared the particles with those found in other ice cores, which record meteorite events on Antarctica 430,000 and 480,000 years ago.

The team observed similarities that suggest the particles resulted from a single-asteroid impact about 430,000 years ago.

They used a combination of numerical simulations with the low oxygen-18 isotope content observed in the particles, to identify their origin.

Noting the lack of a crater tied to the event, Ginneken concluded that the particles reached the ice sheet through projectile vapour jets released by the exploded meteorite, which was likely between 330ft and 500ft in diameter.

This type of explosion is described as intermediate, as it is larger than an airburst, exploding at high altitude, but smaller than an impact cratering event.

CHELYABINSK EVENT: THE LARGEST METEOR STRIKE IN A CENTURY


A meteor that blazed across southern Ural Mountain range in February 2013 was the largest recorded meteor strike in more than a century, after the Tunguska event of 1908.

More than 1,600 people were injured by the shock wave from the explosion, estimated to be as strong as 20 Hiroshima atomic bombs, as it landed near the city of Chelyabinsk.

The fireball measuring 18 meters across, screamed into Earth's atmosphere at 41,600 mph.

Much of the meteor landed in a local lake called Chebarkul.

The findings indicate an impact much more hazardous than the Tunguska and Chelyabinsk events over Russia in 1908 and 2013, respectively.

This research, published by Science Advances, guides an important discovery for the geological record where evidence of such events in scarce. .

The study highlights the importance of reassessing the threat of medium-sized asteroids, as it is likely that similar touchdown events will produce similar particles.

Such an event would be entirely destructive over a large area, corresponding to the area of interaction between the hot jet and the ground, the team warned.

Ginneken said: 'To complete asteroid impact record, we recommend that future studies should focus on the identification of similar events on different targets.'

These targets include rocky or shallow oceanic basements, as the Antarctic ice sheet only covers nine per cent of Earth's land surface.

'Our research may also prove useful for the identification of these events in deep sea sediment cores and, if plume expansion reaches landmasses, the sedimentary record,' he added.

While touchdown events may not threaten human activity if occurring over Antarctica, if it was to take place above a densely populated area, it would result in millions of casualties and severe damages over hundreds of miles, they warned.

The findings have been published in the journal Science Advances
