IT NEVER WAS ABOUT THE FETUS IT WAS ABOUT SEX

Women can say no to sex if Roe falls, says architect of Texas abortion ban

The legal architect of the Texas abortion ban has argued in a supreme court brief that overturning Roe v Wade, the landmark decision which guarantees a right to abortion in the US, could cause women to practice abstinence from sexual intercourse as a way to “control their reproductive lives”.

Former Texas solicitor general Jonathan Mitchell, who played a pivotal role in designing the legal framework of the state’s near-total abortion ban, also argued on behalf of anti-abortion group Texas Right to Life that women would still be able to terminate pregnancies if Roe was overturned by traveling to “wealthy pro-abortion” states like California and New York with the help of “taxpayer subsidies”.

“Women can ‘control their reproductive lives’ without access to abortion; they can do so by refraining from sexual intercourse,” Mitchell wrote in the brief. “One can imagine a scenario in which a woman has chosen to engage in unprotected (or insufficiently protected) sexual intercourse on the assumption that an abortion will be available to her later. But when this court announces the overruling of Roe, that individual can simply change their behavior in response to the court’s decision if she no longer wants to take the risk of an unwanted pregnancy.”

The supreme court is due to hear a Mississippi case this term that experts say could lead to the reversal of the Roe decision by the court’s conservative majority. The argument was made in an amicus, or “friend of the court”, brief in which outside parties can present arguments on cases before the court. The brief was filed on 29 July, about four weeks before Texas’s abortion ban went into effect.

In the same brief, which calls for Roe to be overturned, Mitchell and co-counsel Adam Mortara, an anti-abortion activist and lawyer who clerked for the supreme court justice Clarence Thomas, said such a decision could open the door for other “lawless” rights and protections to be reversed, including the right to have gay sex and the right to same-sex marriage.

The lawyers argued that while it was not necessary for the high court to immediately overrule the legal cases that enshrine those rights, “neither should the court hesitate to write an opinion that leaves those decisions hanging by a thread”.

Those cases (Lawrence, which outlawed criminal sanctions against people who engaged in gay sex, and Obergefell, which legalized same-sex marriage) were “far less hazardous to human life”, they said, but just “as lawless as Roe”.

It is common for high-profile cases such as the Mississippi abortion case to elicit amicus briefs by activists and lawyers who are seeking to weigh in on the legal debate.

But Mitchell and Mortara’s brief is significant because conservatives on the high court recently ruled in a controversial 5-4 decision to allow a Texas law to stand that was designed by Mitchell and in effect bans abortions after about six weeks, before most people know they are pregnant.

While the majority of the justices stressed that they had not yet ruled on the constitutionality of the Texas law itself, the ruling showed that the majority was receptive to Mitchell’s legal strategy.

The abortion case the supreme court will hear this term centers on the legality of a Mississippi law that can ban abortion at 15 weeks gestation. Roe gives pregnant women the right to an abortion up to roughly 24 weeks, or the point at which a fetus can live outside the womb.

The court’s decision to hear the case has alarmed reproductive rights advocates because it blatantly violates the standard set by Roe. Now, in the wake of Texas’s near-total abortion ban, the possibility that the court could overturn the constitutional right to abortion has come into sharp focus. Such a ruling could come in spite of polls that show most Americans believe abortion should be legal in most circumstances.

At the heart of Mitchell and Mortara’s argument in the Mississippi case lies the view that overturning Roe would not outlaw all abortion in the US, but would “merely” return the issue to individual states, which could individually decide whether to ban or restrict terminations. More than half of US states are hostile to abortion rights.

“But women who reside in those states can travel to pro-abortion states to get their abortions – and there is no shortage of ‘abortion funds’ throughout the country that are eager to pay the travel costs and abortion-related costs for indigent women who are seeking to abort their pregnancies,” they said.

Mitchell has been the subject of media attention since it became clear that he had helped devise the Texas law, which allows private citizens to sue anyone “aiding or abetting” a pregnant woman in obtaining an abortion past roughly six weeks.

This structure, which one legal expert called a “fig leaf” for the state, led to the supreme court’s refusal to block the law, with a 6-3 majority describing the law as presenting “complex antecedent procedural questions” that needed to be litigated.

Mitchell has been portrayed in some media accounts as an outsider in the conservative judicial network that has led the drive to seat anti-abortion judges and justices in the past decades. But an examination of Mitchell’s record has found that the former clerk for Antonin Scalia, the late conservative supreme court justice, has ties to groups and organizations that are at the heart of the conservative movement. Those organizations, in turn, have direct links to conservative members of the court.

In 2016, in emails that were released after a Freedom of Information Act request, Mitchell’s name was raised by Henry Butler, the then dean of the George Mason Law School, as a person that he and Leonard Leo, the head of the conservative Federalist Society, would consider hiring.

Leo, who is known to have selected a short list of potential supreme court nominees for Donald Trump when he entered office, has been credited by conservatives for building a court that would – someday – overturn Roe.


Texas’s largest companies stay silent on state abortion ban despite outrage

Friends and colleagues of Mitchell say that Mitchell and Leo do not have an especially close relationship.

In 2019 the powerful, conservative religious law group Alliance Defending Freedom (ADF) began paying Mitchell’s private law firm for services listed as “religious freedom”. The more than $36,517 payment came as Mitchell was simultaneously building case law on his unusual legal theory, the very same provision that would come to define Texas’s six-week abortion ban called SB8.

In an email, Mitchell declined to respond to the Guardian’s questions about the nature of his work for ADF.

ADF was in the spotlight in 2020 after it emerged that Trump’s final nominee to serve on the court, Amy Coney Barrett, was a paid speaker for a program run by ADF, which was established to inspire a “distinctly Christian worldview in every area of law”. The head of the organization, Michael Farris, attended the infamous Rose Garden event in which Barrett was nominated to replace Ruth Bader Ginsburg. The event would later emerge as a super spreader event in which multiple individuals, including possibly Trump, contracted Covid-19.

Texas anti-abortion law shows ‘terrifying’ fragility of women’s rights, say activists

The new anti-abortion law in Texas is a “terrifying” reminder of the fragility of hard-won rights, pro-choice activists have said, as they warn of a “more aggressive, much better organised [and] better funded” global opposition movement.

Pro-choice campaigners have seen several victories in recent years, including in Ireland, Argentina and, most recently, Mexico, where the supreme court ruled last week that criminalising abortion was unconstitutional. Another is hoped for later this month when the tiny enclave of San Marino, landlocked within Italy, holds a highly charged referendum.


But Texas’s law, which bans abortions after about six weeks, once embryonic cardiac activity is detected, and does not make exceptions for incest or rape, has sent shock waves around the world, making pro-choice activists realise they can take nothing for granted.


Mexico activists celebrate abortion ruling as a sign of culture change


Sarah Shaw, head of advocacy at MSI Reproductive Choices, said: “Even though we have seen little gains here and there, in some places, we can never, ever be complacent because we’re only ever really hanging on to these rights by the skin of our teeth.”

She said the Texas law was “really terrifying” because of the emboldening message it sent to other anti-choice governments and organisations, with the fact it had happened in the US giving it “a huge weight and legitimacy”.

“This is all happening in the context of a rising, much more aggressive, much better organised, better funded and much more legitimised opposition movement than we’ve ever seen before,” Shaw said.

Pro-choice campaigners say they have faced increasingly vocal opposition from organisations that started on the US religious right but have spread to other countries, such as 40 Days for Life, a group that distributes graphic and misleading leaflets to women outside UK abortion clinics.

Heartbeat International, a conservative US Christian federation, funds and coordinates a network of anti-abortion “pregnancy resource” centres, many of them in sub-Saharan Africa, to provide women with what it calls “true reproductive help”.

“It’s a transnational movement now,” said Shaw. “What we’re seeing is them [US organisations] exporting their playbooks and their money overseas.”

Attacks on abortion rights usually happen in countries where other human rights are under threat, according to analysts. Last year, more than 30 countries, many of them led by authoritarian strongmen or rightwing populists, including Belarus, Uganda, Hungary, Egypt and Donald Trump’s US administration, signed a non-binding anti-abortion document known as the Geneva consensus declaration. The text was also seen as being anti-LGBTQ, as most of the signatories had not legalised same-sex marriage and several prosecute their LGBTQ+ citizens.

In one of his first acts as president, Joe Biden removed the US from the declaration in January, as well as ending the Mexico City policy, known as the “global gag rule”.

Among the signatories was Poland, which is one of only three countries to have significantly rolled back abortion rights since 2000, according to the Guttmacher Institute. The other two are Nicaragua and the US.

In October last year, Poland’s constitutional tribunal ruled that terminations due to foetal defects were unconstitutional. Three months later, a near-total ban on abortions was imposed. Abortion is now only legal in the case of rape, incest or a threat to the mother’s health.

Meanwhile, human rights observers have said that a Nicaraguan law punishing abortion without any exceptions, passed in 2006, has simply forced women to seek unsafe backstreet terminations.

Marge Berer, coordinator of the International Campaign for Women’s Right to Safe Abortion, said setbacks were all too common, with breakthrough moments often followed by backlashes.

“My experience of this is one step forward, two steps forward, or one step back, 10 steps back,” she said. “And much of it, if not all of it, depends on who is the head of the government of the day.”

Berer, who has been involved in the pro-choice movement for almost 40 years, said the overall picture was brighter than it had been then: fewer deaths from unsafe abortions, and many more countries where terminations are legal.

But, she added, she was not hugely optimistic about the future. “There’s so much misogyny in the world. And I don’t know how anybody is going to make that go away,” she said. “For me, that’s the real problem. It’s that when misogyny takes over on a policy level, it’s very nasty.”

However, there is more hope among activists in Latin America, where the marea verde, or green wave, has swept through first Argentina and, last week, Mexico, where the supreme court struck down a state law that imposed prison terms for having an abortion. While it did not automatically legalise abortion, the decision is thought to set a binding precedent for the country’s judges.

Eugenia López Uribe, regional director of the International Planned Parenthood Federation, said the legal change was the result of “40 years of hard work” by campaigners, with mass demonstrations, backroom lobbying and “a mainstreaming” of women’s rights in public discourse.

She said the ability of the Catholic church to tell people what to do when it came to abortion and contraception had been greatly reduced. “What we know from different surveys … is that in reality Catholics … feel that this is a private decision that you have to do with your own conscience.”


‘Treating us like criminals’: Texas abortion ban creates chilling effect across state

As women in Texas bear the brunt of the law brought in by the governor, Greg Abbott, their Mexican allies across the border were planning to take the fight north, she added.

“The ‘green wave’ hasn’t reached the United States so this is a very good opportunity for [it] to cross the border of the Rio Grande and go to the United States. We can make it go even further. We’ve been used to thinking about it in Latin America. Now is the time for North America.”

90% of global farm subsidies damage people and planet, says UN

Almost half a trillion dollars of support a year harms people’s health, the climate and drives inequality

Almost 90% of the $540bn in global subsidies given to farmers every year are “harmful”, a startling UN report has found.

This agricultural support damages people’s health, fuels the climate crisis, destroys nature and drives inequality by excluding smallholder farmers, many of whom are women, according to the UN agencies.

The biggest sources of greenhouse gas emissions, such as beef and milk, received the biggest subsidies, the report said. These are often produced by large industrialised groups that are best placed to gain access to subsidies.

Without reform, the level of subsidies was on track to soar to $1.8tn (£1.3tn) a year by 2030, further harming human wellbeing and worsening the planetary crisis, the UN said.

Support for the “outsized” meat and dairy industry in rich countries must be reduced, while subsidies for polluting chemical fertilisers and pesticides must fall in lower-income countries, the analysis said.

The report, published before a UN food systems summit on 23 September, said repurposing the subsidies to beneficial activities could “be a game changer” and help to end poverty, eradicate hunger, improve nutrition, reduce global heating and restore nature. Good uses of public money could include supporting healthy food, such as vegetables and fruit, improving the environment and supporting small farmers.

Numerous analyses in recent years have concluded the global food system is broken, with more than 800 million people experiencing chronic hunger in 2020 and 3 billion unable to afford a healthy diet, while 2 billion people are obese or overweight, and a third of food is wasted. The total damage caused has been estimated at $12tn a year, more than the value of the food produced.


$1m a minute: the farming subsidies destroying the world - report

The report was published by the UN Food and Agriculture Organization (FAO), the UN Development Programme (UNDP) and the UN Environment Programme (UNEP) and is an underestimate of the total subsidies in the food system, as it only includes those for which reliable data is available in 88 countries.

“This report is a wake-up call for governments around the world to rethink agricultural support schemes to make them fit for purpose to transform our agri-food systems and contribute to the four betters: better nutrition, better production, better environment and a better life,” said Qu Dongyu, the FAO director general.

The UNDP head, Achim Steiner, said redirecting the subsidies would also boost the livelihoods of the 500 million smallholder farmers worldwide by ensuring a more level playing field with industrial agriculture.

Marco Sánchez, the FAO deputy director and an author of the report, said: “Current support to farms needs transforming for today’s realities. For instance, the US is now aligning to the Paris climate agreement, which is very welcome, but there is no way they can achieve those climate goals if they don’t tackle the food industries.”

Joy Kim, at UNEP, said: “Agriculture contributes a quarter of greenhouse gas emissions, 70% of biodiversity loss and 80% of deforestation.” She said international finance pledges for climate change were $100bn a year and $5bn a year for deforestation. “But governments are providing $470bn [in farm support] that has a huge damaging impact on climate and nature.”

The report found that between 2013 and 2018, support to farmers totalled an average of $540bn a year, of which 87% ($470bn) was “harmful”. This included price incentives for specific livestock and crops, subsidies for fertilisers and pesticides, and distorting export subsidies and import tariffs.

These damage health by promoting the overconsumption of meat in rich countries and overconsumption of low-nutrition staples in poorer ones. “If you are not promoting fruits and vegetables, then in relative terms it is very expensive for the consumer to eat healthily,” said Sánchez. “That’s why 2 billion people in the world cannot afford a healthy diet.”

The report highlighted some cases of positive action, such as moves in China to cut chemical fertiliser and pesticide use, and the zero budget natural farming policy in the Indian state of Andhra Pradesh.

The UK is also shifting its £3bn-a-year subsidy scheme towards environmental goals. Some subsidies should also be redirected to help farmers cope with the increasing extreme weather impacts of the climate crisis, the report said.

The EU is to pay €387bn (£330bn) in farm subsidies from 2021 to 2027, but last Thursday green MEPs in Brussels said a planned overhaul failed to align agriculture with EU climate change targets.

Overhauling farm support in the face of vested interests was hard, said Sánchez, but could be done by spelling out the costs to governments, by consumers demanding better and by financial institutions stopping lending to damaging activities.

“The true costs of our food system have been hidden for too long,” said Morgan Gillespy, the programme director at the Food and Land Use Coalition. The damage caused to nature by subsidy regimes was $4tn to $6tn, according to a recent review, she said.

“Changes in subsidy regimes are likely to be politically controversial and could spark protests among farmers and other groups,” Gillespy said. “But just because it is hard, doesn’t mean it shouldn’t happen. The facts are now clear.”

Consultation with farmers was vital, she said. Copa-Cogeca, the largest interest group for Europe’s farmers did not respond to a request for comment.

A separate report, published by the World Resources Institute in August, said without reform, farm subsidies “will render vast expanses of healthy land useless”.

It said: “Given that the world will have 10 billion people by 2050, the loss of this land will make it impossible to feed the global population.”

Instead, farmers should be supported to restore their land through techniques such as agroforestry, it said.

Empty shelves in supermarkets have reminded us that our food supply is rather more fragile than we thought. Indeed, who would have believed that in 2021 we need a cabinet minister responsible for the supply of food? Whatever the reasons for the situation, this might be a sign of the future. Ensuring food security in the long term could prove much more challenging than our short-term problems. Even amid the pandemic, it is hard to ignore the floods, wildfires and hurricanes occurring with ever-increasing ferocity. The climate emergency now feels very real and doing nothing is no longer an option.

I study plant diseases, many of which are serious threats to humankind. The rice blast fungus, my main obsession, destroys enough rice each year to feed 60 million people. We are already seeing the effects of climate change with new plant diseases moving rapidly around the world and need new disease-resistant crops to combat these threats.

Conventionally, we have created these through plant breeding. However, this is a long process, requiring skill and patience. We must act more quickly given the magnitude of the climate emergency. The predicted increase in the human population and greater urbanisation mean we will also need to grow much more food on much less land, in a way that does not damage the planet.

However, we are still struggling to find sustainable solutions to plant diseases that have plagued us for centuries. One example that is relevant to the history of the British Isles is potato late blight, which causes about $5bn (£3.6bn) in losses worldwide each year. This is the disease that caused the Irish potato famine in the 1840s from which the Irish population has yet to fully recover. The warm and humid late summers of these islands mean that late blight is a constant threat for potato farmers. Currently, we spray 15 to 20 times a year with fungicides to control the disease. These agrochemicals are not only expensive, but entirely fossil-fuel based.

It has been reported that the government is looking to relax the rules on genome editing following departure from the EU. In a consultation earlier this year, the Department for Environment, Food and Rural Affairs recently asked whether genome editing should be treated in the same way as genetic modification (GM) is regulated under EU law. With genome editing, very small and specific changes are made to a plant gene that can have a significant impact on that plant’s resilience to its environment and ability to grow with fewer inputs, such as lower nitrogen levels. We can thereby achieve the outcomes of plant breeding, which has been so successful in improving crop yields, but in a much more precise manner. Genome editing has considerable promise in accelerating plant breeding and the decision to proceed would be very welcome, but where does this leave the debate on GM crops?

Take, for instance, the situation with potato blight. Research at the Sainsbury Laboratory, led by my colleague Professor Jonathan Jones, has already discovered many resistance genes from close relatives of commercial potatoes. We know that, if introduced through genetic modification, these genes enable potatoes to detect the disease and activate natural defences. This works in the field. If British farmers could access these resistant potato varieties, it would immediately lead to a substantial reduction in the carbon footprint of agriculture.

The perception that GM is more disruptive and less safe than genome editing is not based in scientific evidence

GM therefore enables innovation in ways that cannot be achieved just through genome editing; by moving genes from one plant to another we can achieve a blight-resistant potato. The perception that genetic modification is more disruptive, and therefore less safe, than genome editing is not based in scientific evidence. These crops have been subject to more than 4,400 risk assessments by regulatory experts in 71 countries and no increased risk to humans or the environment has been revealed. They have been consumed by more than 350 million people for more than 25 years with no recorded ill-effects. Both methods offer potential solutions to different aspects of our food security problems.

These genetic technologies could be vital in achieving net-zero carbon agriculture within the critical timeframe. Yet they are only one of a set of tools that we will need – there is no single “magic bullet” solution. Many facets of our farming methods need to change, in addition to crop breeding methods. Organic farming has provided us with creative and powerful alternatives for how we grow food. By combining the benefits of ecologically sensitive organic production with innovation in crop improvement, we could develop powerful holistic solutions for sustainable agriculture. For this to happen, however, we need to focus on the shared objectives of the proponents of genetic technologies and those environmental groups who oppose these methods. Both sides want to neutralise the pressure of farming on our ecosystems by reducing chemical inputs.

We need a robust, transparent regulatory framework for genetic technologies in crop development. This is vital for public confidence in these methods, but also needs to be part of a national debate about the innovations necessary to change agriculture and to provide clear consumer benefits.

Regulations should focus on novel crop varieties being safe, healthy, nutritious and environmentally beneficial, rather than the technologies used to produce them. We have an opportunity to make British agriculture world-leading in sustainability, rather than having innovations crippled by excessively stringent regulations based on outdated knowledge and media-driven fears.

There is a real opportunity for these technologies to underpin the changes to our agricultural system that we so desperately need, and to do it relatively quickly. A good starting point would be to shift the conversation away from where we disagree to where we definitely agree – a future in which we can grow more healthy and nutritious food on less land and finally get off the chemical treadmill.

NASA Selects Five U.S. Companies – Including SpaceX and Blue Origin – for Artemis Lunar Lander Concepts

By NASA SEPTEMBER 18, 2021

NASA has selected five U.S. companies to help the agency enable a steady pace of crewed trips to the lunar surface under the agency’s Artemis program. These companies will make advancements toward sustainable human landing system concepts, conduct risk-reduction activities, and provide feedback on NASA’s requirements to cultivate industry capabilities for crewed lunar landing missions.

The awards under the Next Space Technologies for Exploration Partnerships (NextSTEP-2) Appendix N broad agency announcement are firm fixed-price, milestone-based contracts. The total combined value for the awards is $146 million, and the work will be conducted over the next 15 months. The companies that received awards and their award values are:  

• Blue Origin Federation of Kent, Washington, $25.6 million. 
• Dynetics (a Leidos company) of Huntsville, Alabama, $40.8 million.
• Lockheed Martin of Littleton, Colorado, $35.2 million.
• Northrop Grumman of Dulles, Virginia, $34.8 million.
• SpaceX of Hawthorne, California, $9.4 million.

“Establishing a long-term human presence on the Moon through recurring services using lunar landers is a major Artemis goal,” said Kathy Lueders, NASA’s associate administrator for Human Exploration and Operations at Headquarters in Washington. “This critical step lays the foundation for U.S. leadership in learning more about the Moon and for learning how to live and work in deep space for future missions farther into the solar system.”

The selected companies will develop lander design concepts, evaluating their performance, design, construction standards, mission assurance requirements, interfaces, safety, crew health accommodations, and medical capabilities. The companies will also mitigate lunar lander risks by conducting critical component tests and advancing the maturity of key technologies.

The work from these companies will ultimately help shape the strategy and requirements for a future NASA’s solicitation to provide regular astronaut transportation from lunar orbit to the surface of the Moon.

“Collaboration with our partners is critical to achieving NASA’s long-term Artemis lunar exploration goals,” said Lisa Watson-Morgan, Human Landing System Program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “By partnering with innovative U.S. companies, we will establish a robust lunar economy while exploring new areas of the Moon for generations to come.”

This opportunity is distinct from the initial crewed lunar landing demonstration mission awarded under the NextSTEP-2 Appendix H procurement, which will serve as the proof of concept for the Artemis architecture.

NASA’s goals under Artemis include enabling a safe and cost-efficient long-term approach to accessing the lunar surface and becoming one of multiple customers purchasing services in a lunar transportation market. Much of what the agency develops for the Moon will be applied to future exploration at Mars.

NASA’s Artemis missions include landing the first woman and first person of color on the lunar surface, sending a suite of new science instruments and technology demonstrations to study the Moon, and establishing a long-term presence there.

Australian scholar hails success of China's crewed mission for space station construction

2021-09-18 15:48:22XinhuaEditor : Xue Lingqiao

The success of China's first manned flight during the construction of its space station showed the country's ambition and space capability, said an Australian scholar in astrophysics.

Brad Tucker, an astrophysicist and cosmologist at the Australian National University (ANU), told Xinhua on Saturday that the task was a great step to getting the Tiangong space station ready.

"The taikonauts did a lot of work in establishing the Tiangong space station for full operation, with multiple spacewalks and upgrades," he said. "This is exactly the work they needed to accomplish to progress the building of Tiangong to full operations."

He noted that as the International Space Station started to show its age, "it is also important that this (Tiangong) is operating and can perform science into the future, which was what their 90-day mission was working towards."

"It means that in the future, not just the International Space Station hosts experiments from around the world, so can the Tiangong space station," Tucker said.

Three Chinese astronauts, the first sent to orbit for China's space station construction, have completed their three-month mission and returned to Earth safely on Friday.

The success of the Shenzhou-12 manned spaceflight mission laid a solid foundation for the continued construction and operation of the country's space station, said the China Manned Space Agency.

Do the northern lights make sounds that you can hear?

September 16, 2021 10.17am EDT


It’s a question that has puzzled observers for centuries: do the fantastic green and crimson light displays of the aurora borealis produce any discernible sound?

Conjured by the interaction of solar particles with gas molecules in Earth’s atmosphere, the aurora generally occurs near Earth’s poles, where the magnetic field is strongest. Reports of the aurora making a noise, however, are rare – and were historically dismissed by scientists.

But a Finnish study in 2016 claimed to have finally confirmed that the northern lights really do produce sound audible to the human ear. A recording made by one of the researchers involved in the study even claimed to have captured the sound made by the captivating lights 70 metres above ground level.



Still, the mechanism behind the sound remains somewhat mysterious, as are the conditions that must be met for the sound to be heard. My recent research takes a look over historic reports of auroral sound to understand the methods of investigating this elusive phenomenon and the process of establishing whether reported sounds were objective, illusory of imaginary.

Historic claims

Auroral noise was the subject of particularly lively debate in the first decades of the 20th century, when accounts from settlements across northern latitudes reported that sound sometimes accompanied the mesmerising light displays in their skies.

Witnesses told of a quiet, almost imperceptible crackling, whooshing or whizzing noise during particularly violent northern lights displays. In the early 1930s, for instance, personal testimonies started flooding into The Shetland News, the weekly newspaper of the subarctic Shetland Islands, likening the sound of the northern lights to “rustling silk” or “two planks meeting flat ways”.

These tales were corroborated by similar testimony from northern Canada and Norway. Yet the scientific community was less than convinced, especially considering very few western explorers claimed to have heard the elusive noises themselves.

The credibility of auroral noise reports from this time was intimately tied to altitude measurements of the northern lights. It was considered that only those displays that descended low into the Earth’s atmosphere would be able to transmit sound which could be heard by the human ear.

The problem here was that results recorded during the Second International Polar Year of 1932-3 found aurorae most commonly took place 100km above Earth, and very rarely below 80km. This suggested it would be impossible for discernible sound from the lights to be transmitted to the Earth’s surface.

Auditory illusions?

Given these findings, eminent physicists and meteorologists remained sceptical, dismissing accounts of auroral sound and very low aurorae as folkloric stories or auditory illusions.

Sir Oliver Lodge, the British physicist involved in the development of radio technology, commented that auroral sound might be a psychological phenomenon due to the vividness of the aurora’s appearance – just as meteors sometimes conjure a whooshing sound in the brain. Similarly, the meteorologist George Clark Simpson argued that the appearance of low aurorae was likely an optical illusion caused by the interference of low clouds.

Nevertheless, the leading auroral scientist of the 20th century, Carl Størmer, published accounts written by two of his assistants who claimed to have heard the aurora, adding some legitimacy to the large volume of personal reports.

Størmer’s assistant Hans Jelstrup said he had heard a “very curious faint whistling sound, distinctly undulatory, which seemed to follow exactly the vibrations of the aurora”, while Mr Tjönn experienced a sound like “burning grass or spray”. As convincing as these two last testimonies may have been, they still didn’t propose a mechanism by which auroral sound could operate.

Sound and light

The answer to this enduring mystery which has subsequently garnered the most support was first tentatively suggested in 1923 by Clarence Chant, a well-known Canadian astronomer. He argued that the motion of the northern lights alters Earth’s magnetic field, inducing changes in the electrification of the atmosphere, even at a significant distance.

This electrification produces a crackling sound much closer to Earth’s surface when it meets objects on the ground, much like the sound of static. This could take place on the observer’s clothes or spectacles, or possibly in surrounding objects including fir trees or the cladding of buildings.

Chant’s theory correlates well with many accounts of auroral sound, and is also supported by occasional reports of the smell of ozone – which reportedly carries a metallic odour similar to an electrical spark – during northern lights displays.

Yet Chant’s paper went largely unnoticed in the 1920s, only receiving recognition in the 1970s when two auroral physicists revisited the historical evidence. Chant’s theory is largely accepted by scientists today, although there’s still debate as to how exactly the mechanism for producing the sound operates.

What is clear is that the aurora does, on rare occasions, make sounds audible to the human ear. The eerie reports of crackling, whizzing and buzzing noises accompanying the lights describe an objective audible experience – not something illusory or imagined.

Sampling the sound

If you want to hear the northern lights for yourself, you may have to spend a considerable amount of time in the Polar regions, considering the aural phenomenon only presents itself in 5% of violent auroral displays. It’s also most commonly heard on the top of mountains, surrounded by only a few buildings – so it’s not an especially accessible experience.

In recent years, the sound of the aurora has nonetheless been explored for its aesthetic value, inspiring musical compositions and laying the foundation for novel ways of interacting with its electromagnetic signals.

The Latvian composer Ēriks Ešenvalds has used journal extracts from the American explorer Charles Hall and the Norwegian statesman Fridjtof Nansen, both of whom claimed to have heard the northern lights, in his music. His composition, Northern Lights, interweaves these reports with the only known Latvian folksong recounting the auroral sound phenomenon, sung by a tenor solo.

Or you can also listen to the radio signals of the northern lights at home. In 2020, a BBC 3 radio programme remapped very low frequency radio recordings of the aurora onto the audible spectrum. Although not the same as perceiving audible noises produced by the the northern lights in person on a snowy mountaintop, these radio frequencies give an awesome sense of the aurora’s transitory, fleeting and dynamic nature.

What role for small modular nuclear reactors in combating climate change?

Time, a steep ‘learning curve,’ and, of course, costs pose daunting challenges for those backing small modular nuclear reactors.

by PETER SINCLAIR

SEPTEMBER 14, 2021


Does the potential of small modular nuclear reactor technology make it a viable approach to helping solve climate change challenges not fully met by renewable energy sources such as wind and solar?

Experts interviewed in this Yale Climate Connections “This is Not Cool” original video in some cases hold out hope. But they also confront timing, economic, and communications obstacles that could be prohibitive.

Other Lab Chief Executive Officer Saul Griffith voices what he characterizes as “an extraordinary position … but hopefully not too extraordinary a postilion.” Nuclear energy, Griffith says, “has been pretty reliable and very safe and compared to other energy sources, all told, reasonably priced …. and good.” But he backtracks some: He readily acknowledges “huge political headwinds” and concerns about availability of adequate cooling water supplies, a view expressed also by water resources expert Peter Gleick. Griffith points to what many – among them proponents of nuclear energy – fear may be an Achilles heel: “It’s unclear if safe and reliable nuclear energy can compete with just where solar and wind are going …. That’s the reality.”

University of California Berkeley nuclear engineering professor Daniel Kammen says he’s hoping nuclear energy can fill some needs that renewables may not resolve. But he points to a stiff “learning curve.” In addition, Kammen says “There’s more work to be done on nuclear than on any other area for it to be a competitor.”

Less optimistic on the new nuclear technology is Arjun Makhijani of the Institute for Energy and Environmental Research. He says small modular reactors are attracting a lot of interest in part because “big ones have failed.” He is concerned by projections that the reality of small modular nuclear reactors may be close to a decade away. Too long a wait, Makhijani says: “We must have overwhelming momentum to zero carbon energy by that time.”

In the other corner, as one might say of a prize fight, is Microsoft founder Bill Gates, a bit more optimistic – or at a minimum more hopeful – than the others: “Nuclear power can be done in a way so that none of those nuclear failures of the past would recur because of just the physics” of small modular nuclear design.

“Convincing people of that may be just as hard as actually building it,” Gates tells CNN’s Anderson Cooper. But nuclear power “may be necessary because of climate change, so we shouldn’t give up.”

Mysterious results in an experiment may be due to dark energy

Shane McGlaun - Sep 16, 2021, 

One of the most mysterious subjects that scientists around the world are studying is called dark energy. Scientists believe dark energy is the mysterious force that leads to acceleration in the universe. A team of researchers from the University of Cambridge has published a study that suggests unexplained results obtained from an experiment conducted in Italy called XENON1T could have been caused by dark energy.

Interestingly, the experiment was designed to detect dark matter, but Cambridge scientists believe dark energy could account for the mysterious and unexplained results from the experiment. In the study, physical models were constructed in an attempt to explain the experiment results. Study researchers believe the experiment results could have been caused by dark energy particles in a region of the sun dominated by strong magnetic fields.

Unfortunately, additional experiments will be required to confirm their theory. Nevertheless, scientists are excited at the possibility of the discovery of dark energy. Currently, estimates predict that everything we can see with our eyes in the universe accounts for less than five percent of what’s there. Most of the material in the universe is dark, and theories suggest 27 percent of the entire universe is dark matter.

Dark matter is described as a force that holds galaxies and the cosmos itself together. Scientists also believe that 68 percent of the universe is made up of dark energy causing the universe to expand and accelerate. Since both dark matter and dark energy are invisible, little is known about them.

The presence of dark matter was first theorized in the 1920s, but dark energy wasn’t discovered until 1998. Scientists say that while the experiment was intended to detect dark matter, detecting dark energy is even more difficult. The study comes after the XEON1T experiment discovered an unexpected signal about a year ago that was higher than the expected background. Researchers on this study decided to explore a model where the unexpected signal was attributed to dark energy rather than dark matter. Scientists admit they are still far from understanding dark energy, and additional experiments are needed.

Have we detected dark energy? Scientists say it's a possibility

A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, and not the dark matter the experiment was designed to detect.

They constructed a physical model to help explain the results, which may have originated from dark energy particles produced in a region of the Sun with strong magnetic fields, although future experiments will be required to confirm this explanation. The researchers say their study could be an important step toward the direct detection of dark energy.

Everything our eyes can see in the skies and in our everyday world—from tiny moons to massive galaxies, from ants to blue whales—makes up less than five percent of the universe. The rest is dark. About 27% is dark matter—the invisible force holding galaxies and the cosmic web together—while 68% is dark energy, which causes the universe to expand at an accelerated rate.

"Despite both components being invisible, we know a lot more about dark matter, since its existence was suggested as early as the 1920s, while dark energy wasn't discovered until 1998," said Dr. Sunny Vagnozzi from Cambridge's Kavli Institute for Cosmology, the paper's first author. "Large-scale experiments like XENON1T have been designed to directly detect dark matter, by searching for signs of dark matter 'hitting' ordinary matter, but dark energy is even more elusive."

To detect dark energy, scientists generally look for gravitational interactions: the way gravity pulls objects around. And on the largest scales, the gravitational effect of dark energy is repulsive, pulling things away from each other and making the Universe's expansion accelerate.

About a year ago, the XENON1T experiment reported an unexpected signal, or excess, over the expected background. "These sorts of excesses are often flukes, but once in a while they can also lead to fundamental discoveries," said Dr. Luca Visinelli, a researcher at Frascati National Laboratories in Italy, a co-author of the study. "We explored a model in which this signal could be attributable to dark energy, rather than the dark matter the experiment was originally devised to detect."

At the time, the most popular explanation for the excess were axions—hypothetical, extremely light particles—produced in the Sun. However, this explanation does not stand up to observations, since the amount of axions that would be required to explain the XENON1T signal would drastically alter the evolution of stars much heavier than the Sun, in conflict with what we observe.

We are far from fully understanding what dark energy is, but most physical models for dark energy would lead to the existence of a so-called fifth force. There are four fundamental forces in the universe, and anything that can't be explained by one of these forces is sometimes referred to as the result of an unknown fifth force.

However, we know that Einstein's theory of gravity works extremely well in the local universe. Therefore, any fifth force associated to dark energy is unwanted and must be 'hidden' or 'screened' when it comes to small scales, and can only operate on the largest scales where Einstein's theory of gravity fails to explain the acceleration of the Universe. To hide the fifth force, many models for dark energy are equipped with so-called screening mechanisms, which dynamically hide the fifth force.

Vagnozzi and his co-authors constructed a physical model, which used a type of screening mechanism known as chameleon screening, to show that dark energy particles produced in the Sun's strong magnetic fields could explain the XENON1T excess.

"Our chameleon screening shuts down the production of dark energy particles in very dense objects, avoiding the problems faced by solar axions," said Vagnozzi. "It also allows us to decouple what happens in the local very dense Universe from what happens on the largest scales, where the density is extremely low."

The researchers used their model to show what would happen in the detector if the dark energy was produced in a particular region of the Sun, called the tachocline, where the magnetic fields are particularly strong.

"It was really surprising that this excess could in principle have been caused by dark energy rather than dark matter," said Vagnozzi. "When things click together like that, it's really special."

Their calculations suggest that experiments like XENON1T, which are designed to detect dark matter, could also be used to detect dark energy. However, the original excess still needs to be convincingly confirmed. "We first need to know that this wasn't simply a fluke," said Visinelli. "If XENON1T actually saw something, you'd expect to see a similar excess again in future experiments, but this time with a much stronger signal."

If the excess was the result of dark energy, upcoming upgrades to the XENON1T experiment, as well as experiments pursuing similar goals such as LUX-Zeplin and PandaX-xT, mean that it could be possible to directly detect dark energy within the next decade.

Dark Energy Could Be Responsible for Mysterious Experiment Signals, Researchers Say

What if a bunch of liquid xenon under the Apennine Mountains found 68% of the universe?

A team of physicists at the University of Cambridge suspects that dark energy may have muddled results from the XENON1T experiment, a series of underground vats of xenon that are being used to search for dark matter.


Dark matter and dark energy are two of the most discussed quandaries of contemporary physics. The two darks are placeholder names for mysterious somethings that seem to be affecting the behavior of the universe and the stuff in it. Dark matter refers to the seemingly invisible mass that only makes itself known through its gravitational effects. Dark energy refers to the as-yet unexplained reason for the universe’s accelerating expansion. Dark matter is thought to make up about 27% of the universe, while dark energy is 68%, according to NASA.

Physicists have some ideas to explain dark matter: axions, WIMPs, SIMPs, and primordial black holes, to name a few. But dark energy is a lot more enigmatic, and now a group of researchers working on XENON1T data says an unexpected excess of activity could be due to that unknown force, rather than any dark matter candidate. The team’s research was published this week in Physical Review D.

The XENON1T experiment, buried below Italy’s Apennine Mountains, is set up to be as far away from any noise as possible. It consists of vats of liquid xenon that will light up if interacted with by a passing particle. As previously reported by Gizmodo, in June 2020 the XENON1T team reported that the project was seeing more interactions than it ought to be under the Standard Model of physics, meaning that it could be detecting theorized subatomic particles like axions—or something could be screwy with the experiment.

“These sorts of excesses are often flukes, but once in a while they can also lead to fundamental discoveries,” said Luca Visinelli, a researcher at Frascati National Laboratories in Italy and a co-author of the study, in a University of Cambridge release. “We explored a model in which this signal could be attributable to dark energy, rather than the dark matter the experiment was originally devised to detect.”

“We first need to know that this wasn’t simply a fluke,” Visinelli added. “If XENON1T actually saw something, you’d expect to see a similar excess again in future experiments, but this time with a much stronger signal.”


Despite constituting so much of the universe, dark energy has not yet been identified. Many models suggest that there may be some fifth force besides the known four known fundamental forces in the universe, one that is hidden until you get to some of the largest-scale phenomena, like the universe’s ever-faster expansion.

Axions shooting out of the Sun seemed a possible explanation for the excess signal, but there were holes in that idea, as it would require a re-think of what we know about stars. “Even our Sun would not agree with the best theoretical models and experiments as well as it does now,” one researcher told Gizmodo last year.

Part of the problem with looking for dark energy are “chameleon particles” (also known as solar axions or solar chameleons), so-called for their theorized ability to vary in mass based on the amount of matter around them. That would make the particles’ mass larger when passing through a dense object like Earth and would make their force on surrounding masses smaller, as New Atlas explained in 2019. The recent research team built a model that uses chameleon screening to probe how dark energy behaves on scales well beyond that of the dense local universe.

“Our chameleon screening shuts down the production of dark energy particles in very dense objects, avoiding the problems faced by solar axions,” said lead author Sunny Vagnozzi, a cosmologist at Cambridge’s Kavli Institute for Cosmology, in a university release. “It also allows us to decouple what happens in the local very dense Universe from what happens on the largest scales, where the density is extremely low.”

The model allowed the team to understand how XENON1T would behave if the dark energy were produced in a magnetically strong region of the Sun. Their calculations indicated that dark energy could be detected with XENON1T.

Since the excess was first discovered, ​​the XENON1T team “tried in any way to destroy it,” as one researcher told The New York Times. The signal’s obstinacy is as perplexing as it is thrilling.

“The authors propose an exciting and interesting possibility to expand the scope of the dark matter detection experiments towards the direct detection of dark energy,” Zara Bagdasarian, a physicist at UC Berkeley who was unaffiliated with the recent paper, told Gizmodo in an email. “The case study of XENON1T excess is definitely not conclusive, and we have to wait for more data from more experiments to test the validity of the solar chameleons idea.”

The next generation of XENON1T, called XENONnT, is slated to have its first experimental runs later this year. Upgrades to the experiment will hopefully seal out any noise and help physicists home in on what exactly is messing with the subterranean detector.
