Climate activist Disha Ravi, and India’s shrinking space for dissent

The arrest of a 22-year-old climate activist in India is an example of the disturbing use of legal power to clamp down on dissent in the world’s largest democracy, write Joanna Slater and Niha Masih

As public enemies go, Disha Ravi is an unlikely candidate. The 22-year-old climate change activist works for a vegan food company and likes to join volunteer clean-up drives. Earlier this month, she helped disseminate a list of peaceful ways to support a major protest by farmers against new agricultural laws.

In today’s India, that was enough to make her a target. Over the weekend, Ravi was arrested. Police accused of her of sedition and conspiring to “spread disaffection” against the state.

Ravi’s arrest is the latest example of a disturbing trend in the world’s largest democracy. The government of Prime Minister Narendra Modi is deploying the country’s legal machinery to suppress opponents in a clampdown on dissent not seen in decades, critics say.

India police arrest climate activist linked to Greta Thunberg movement over protests ‘toolkit’

Modi won a landslide re-election victory in 2019 that made him the most powerful Indian leader since the 1970s. But the country's independent institutions – including the judiciary and the media – have rarely appeared weaker, experts say. Researchers who study democracy around the globe recently put India among a group of nations heading towards autocracy.

Freedom of expression is being curtailed. A comedian was recently kept in jail for more than a month for a joke he did not tell as judges repeatedly denied him bail. The use of internet shutdowns to quell protests and disrupt communication has soared under the Modi government. (India now uses the tactic more than any other country, according to Access Now, an international advocacy group that tracks such suspensions.) The Indian government this month ordered Twitter to block hundreds of accounts linked to the farmer protests.

The filing of sedition cases against people who criticise politicians or governments has also jumped, shows a recent analysis by Article 14, a research and reporting website focused on democratic rights. More than 95 per cent of such sedition cases over the past decade were registered after Modi came to power, it found.

Members of the ruling Hindu nationalist Bharatiya Janata Party reject any suggestion that there is a crackdown on dissent. “India is the largest democracy that humankind has ever seen, with an independent judiciary that routinely rules against the government and free media that daily provides a platform to the government's vocal critics,” says Baijayant Panda, national vice president of the BJP. “These allegations are instigated by the losers of elections in order to try and maintain their own relevance.”

Experts say previous Indian governments also targeted their opponents with politically motivated charges. But some warn that what is currently unfolding goes much further and even see parallels to an infamous period in the country's history known as the Emergency, when the then prime minister Indira Gandhi ruled by decree and suspended civil liberties

“It's a kind of smarter Emergency,” says Pratap Bhanu Mehta, one of India’s leading political scientists. There are no mass arrests of Indian politicians, as the country saw in 1975, but the ruling party has a “creeping stranglehold over all institutions” while opposition parties are weak, Mehta says. “In some sense, I think it’s much more insidious.”

Since November, tens of thousands of farmers have blocked roads in opposition to major changes to agricultural policy

Government pressure on journalists has intensified, and the mainstream media seldom criticises the government. Key agencies are headed by personnel considered loyal to Modi. India’s Supreme Court has delayed rulings on the constitutionality of major government policies, including changes to the status of Kashmir, an overhaul of campaign finance laws and a new pathway to citizenship that some believe undermines India’s secular foundations.

Tarunabh Khaitan, vice dean of the faculty of law at Oxford University, recently wrote a paper describing how India’s constitution is under assault from “a thousand cuts.” India risks becoming a democracy in name only, he said, one where elections continue but the opposition has little chance of taking power.



“We are at the precipice,” Khaitan said in an interview. “Do we jump, or can we slowly, cautiously walk back?

One case that is considered a harbinger for where India is headed began in 2018. More than a dozen activists were arrested and accused of plotting to overthrow the government, charges they denied. All of the activists worked with India’s most disadvantaged communities, including tribal people and Dalits, and were vocal critics of Modi and his party.

Last week, an analysis by a digital forensics firm in the United States concluded that key electronic evidence in the case was planted on a laptop by a hacker using malware. The findings of the forensic report help bolster long-held claims by human rights groups and legal experts that the case was unfounded. Defence lawyers have asked judges to dismiss the case against the activists, although it is unclear when the court will rule.

Students, activists, journalists and nongovernmental organisations are among those who have come under increasing pressure from the authorities. In Kashmir, the government engaged in a months-long crackdown, snapping communications and detaining mainstream politicians. Elsewhere in India, when anti-government protests break out, law enforcement authorities repeatedly find alleged conspiracies – and arrests follow.

In December 2019, protests erupted across the country in response to a new citizenship law that critics say discriminates against Muslims. Dozens of people were killed in Uttar Pradesh, India’s largest state, in the ensuing crackdown. In February, riots broke out in Delhi that left more than 50 people dead, most of them Muslim

In the aftermath, the police charged Muslim students and activists who engaged in protests against the citizenship law with conspiracy to commit violence. Among those arrested were a pregnant graduate student who created a WhatsApp group to coordinate protests, an activist who ran a collective to foster interreligious unity and members of a student group working for women’s rights in university settings.

Harsh Mander, 65, is one of the country's most well-known activists who has worked for years on social justice causes, including efforts to bridge divides between Hindus and Muslims. His name has been mentioned in more than a dozen charging documents connected to the Delhi riots, he says, suggesting he could be arrested at any time as part of the alleged conspiracy.

“It’s like a dagger hung over you,” Mander says. “The hope and expectation is that we would be silent.”

The government’s response to farmer protests outside Delhi is the latest litmus test. Since November, tens of thousands of farmers have blocked roads in opposition to major changes to agricultural policy. While Modi has praised farmers, he has insisted the protesters are being misled. He recently told parliament that the country was facing a class of professional agitators, whom he called “parasites”, and warned of the need to protect the nation from “foreign destructive ideology”.

Two other Indian environmental activists with the climate change group Extinction Rebellion are already facing arrest

On 26 January, clashes broke out between farmers and police officers. Authorities shut down the internet at the protest sites and made dozens of arrests. Police later connected the violence to a “toolkit” tweeted by Swedish climate change activist Greta Thunberg, without citing evidence and despite the fact that the document lists only peaceful modes of protest.

(A toolkit is a document created to explain any issue on the social media. It also provides information on what a person must do to address the particular issue, which could include information on petitions, details about protests and mass movements.)

The police alleged that an organisation linked to the document – the nonprofit Poetic Justice Foundation, based in Canada – had promoted a separatist movement in the state of Punjab.

Ravi, the 22-year-old environmental activist, belonged to a group of young people around the world who joined Thunberg’s Fridays for Future environmental movement. She completed a degree in business administration at a prestigious university in Bangalore.

“Countries like India are already experiencing a climate crisis,” she said in an interview with The Guardian last year. “We’re not just fighting for our future, we are fighting for our present.”

Friends describe Ravi as a hard-working young woman with a slightly goofy side who is the only breadwinner in her family. She is passionate about animals and the environment, says Yuvan Aves, 25, a fellow volunteer in the Indian chapter of Fridays for Future. The message from Ravi's arrest is, “if you ask difficult questions or decide to do something for a good cause, you can be sent to jail,” he says. “For something as harmless as a toolkit.”

On 14 February, Ravi reportedly told a judge in Delhi that she had made minor edits to the toolkit document but did not write it. “We wanted to support the farmers,” she said in court, according to New Delhi Television, briefly breaking down in tears. A lawyer for Ravi declined to comment.

Justice Deepak Gupta, who retired from India’s Supreme Court last year, says the contents of the toolkit that are in the public domain are “not seditious in any manner”. The use of sedition cases in recent years is “a straight-up attempt to stifle the voices of dissent”, he says.

The government has also demanded that Twitter take down hundreds of accounts linked to the farmer protests. The social media company blocked many of the accounts but refused to do the same for handles belonging to journalists, media outlets, politicians and activists, saying it did not believe the “actions we have been directed to take are consistent with Indian law”.

Meanwhile, police in Delhi say their investigation of the toolkit will continue. Two other Indian environmental activists with the climate change group Extinction Rebellion are already facing arrest in the probe. Prem Nath, a senior police official in Delhi, told reporters last week that the activists’ intent was “to propagate the toolkit worldwide”, spur protests at Indian embassies and “tarnish India’s image”.


Protesting Indian farmers vow to amass more supporters outside capital Delhi


By Danish Siddiqui



BARNALA, India (Reuters) - More than 100,000 farmers and farm workers gathered in India’s northern Punjab state on Sunday in a show of strength against new farm laws, where union leaders called on supporters to amass outside the capital New Delhi on Feb. 27.

Tens of thousands of Indian growers have already been camped outside Delhi for nearly three months, demanding the repeal of the three reform laws that they say will hurt them and benefit large corporations.

Prime Minister Narendra Modi’s government, which introduced the laws last September, has offered to defer the laws but refused to abandon them, arguing that legislation will help farmers get better prices


Both sides have met for several rounds of negotiations but failed to make any headway, and farmers’ unions have vowed to carry on the protests until the laws are rolled back.

At Sunday’s rally at a grain market in Barnala, a town in Punjab, union leaders outlined plans to mobilise farmers and farm workers from across the northern state and move to a protest site outside Delhi later this month.

“We came here to make Punjab’s farmers aware of the movement in Delhi. We came to tell them what’s happening there and what will happen next,” prominent farmer leader Joginder Ugrahan told Reuters.

A sea of supporters, including tens of thousands of women, began gathering in Barnala early in the day, riding in on buses, tractors, trailers and cars. Local police estimated a crowd of between 120,000 and 130,000 eventually gathered, comprising one of the largest rallies against the laws.

Baljinder Singh, a 52-year-old farmer, said he had travelled 30 kms (18.6 miles) to attend the rally. “Our objective is that the black laws enacted by the Modi government are repealed,” Singh said, tightly grasping a flag of a farmers’ union.

In New Delhi, a senior official from Modi’s ruling Bharatiya Janata Party blamed opposition parties for attempting to prolong the agitation but said the government was open for further talks.


Nevada Senate passes bill to form 'dark sky places' program

UofA DECLARED LAKE MIQUELON IN ALBERTA A DARK SKY ZONE

CARSON CITY, Nev. — Nevada's state Senate took a step toward ensuring stargazers will continue to enjoy picture-perfect constellations on Monday, passing a bill to recognize “dark sky places” with unobstructed views of galaxies hundreds of thousands of light years away.

The Legislature's upper chamber unanimously passed the proposal to create a state program aligned with the International Dark Sky Association to designate the state's stargazing havens and encourage their use for education, preservation and tourism.

“This increase in attention to Nevada and our dark skies really provides us an opportunity, especially during this pandemic, to capitalize on an asset that we have,” Lt. Gov. Kate Marshall said during a committee hearing last week.

Marshall, who is sponsoring the bill, said Nevada is known among stargazers for having some of the darkest skies in the country.

Her office has worked with the rural Nevada communities of Tonopah and Beatty on tourism initiatives to attract visitors to marvel at the celestial views away from the fluorescent glow of street lights, casinos and tall buildings that remain lit-up at night.

The International Dark Sky Association recognizes 14 dark sky sanctuaries in the world and two are in Nevada: Great Basin National Park in eastern Nevada and the Massacre Rim Wilderness Area in western Nevada, near the state line with Oregon.

The bill does not include provisions to protect dark sky places from development that could bring encroaching light pollution. Marshall said the purpose of the designations was to promote tourism and economic activity for rural communities near dark sky places and their small businesses.

Maine, New Hampshire and New Mexico all have laws on their books to encourage the preservation of dark skies.

State Sen. Julia Ratti, D-Sparks, said protecting Nevada’s dark skies would complement projects underway, including the construction of an observatory in Great Basin National Park in eastern Nevada. Ratti, who serves as director on the Great Basin National Park Foundation’s board, said it would be the first facility of its kind built in a national park.

The bill received support from wilderness advocates, business groups and local officials from throughout rural Nevada, including Lincoln County.

Federal agencies control 98% of the county's land, most of which is overseen by the Bureau of Land Management and the Department of Defence, which owns the Nevada Test and Training Range.

Marcia Hurd, the president of the Lincoln County Tourism Authority, said a lack of land for unrestricted commercial activity led to economic struggles in the county and a reliance on tourism. She hopes dark sky designations will bring additional tourists to eastern Nevada.

“Living in an area where you can clearly see the Milky Way just by stepping out your backdoor is something that everyone should have the opportunity to experience,” Hurd wrote in a letter to the Senate Committee on Natural Resources.

The bill now moves to the Assembly and must be signed by Gov. Steve Sisolak, a Democrat, before becoming law.

ARACHNOPHOBIA
University of Michigan says it shut down a campus library for two days after discovering venomous spiders

By Rebekah Riess and Leah Asmelash, CNN 

It's like something straight out of a nightmare -- venomous spiders were found inside a University of Michigan library, causing the building to be shut down for two days last month.
© Susan Montgomery/Shutterstock Spiders were found in the basement of Shapiro Undergraduate Library at the University of Michigan in January.

The "small number" of venomous Mediterranean recluse spiders were uncovered in the basement mechanical room of Shapiro Undergraduate Library in late January during a routine building check, said university spokesperson Kim Broekhuizen.

Closing the library was a misunderstanding, and there haven't been any other spider sightings since then, she said.

"Based on what we all know now, library managers agree that it was a mistake to close the building and they apologize for the inconvenience to the university community," Broekhuizen said in a statement issued Tuesday.

But the spiders have also been identified in basements and remote areas of other buildings on campus due to low occupancy. Broekhuizen said those buildings are also being treated by pest management.

The Mediterranean recluse spider is a cousin to the brown recluse spider, but is even more reclusive.

"As the name implies, they are reclusive and bites are extremely rare," Anne Danielson-Francois, associate professor of biology at the University of Michigan, said. "Mediterranean recluse spiders prefer basement spaces, tunnels and other hideaways where there is a decrease in foot traffic."

Danielson-Francois worked with the school to determine the identity of the spider, after examining samples found in traps, Broekhuizen said.

The University of Michigan has cautioned those working in basement areas to wear a long-sleeved shirt, hat, gloves and shoes that cover the entire foot when handling stored items, cardboard boxes, lumber or rocks.

It is also asking anyone who sees one of the spiders to contact the campus pest management team.


Loxosceles rufescens, the Mediterranean recluse spider, originated in the Mediterranean region as its name implies, but is now found worldwide. Like other species of the genus Loxosceles, bites from the Mediterranean recluse spider can have dangerous effects, causing skin lesions – a condition known as loxoscelism.
Blood-drenched ‘zombies’ swarm Queensland parliament

Extinction Rebellion protesters dressed up as zombies outside Queensland parliament to campaign for action on climate change.

The undead swarmed the perimeter of parliament and Brisbane's George Street.

Blood-drenched zombies have turned Queensland's parliament and a major road into a dead end in a protest for climate change action.

Extinction Rebellion protesters dressed as the undead swarmed the perimeter of parliament and Brisbane's George Street as politicians were turning up for the first sitting day of the year on Tuesday.

The billionaire, worker and scientist-themed zombies chased MPs, blocked their cars from entering the building and even briefly breached the gates before being pushed out by police.

XR spokesperson Rachel said the demonstration highlighted the lack of state government action on climate change.

"They have yet to declare a climate emergency," she said in a statement.

"They continue to invest in destructive industries and prioritise profit over people; the COVID-19 gas-led recovery plan is just one recent devastating example of that".

The protest was the 10th held by XR in central Brisbane since October with the zombies turning to block George St after being shepherded away from parliament's gates by police.

The demonstrators danced to the Michael Jackson hit Thriller or laid down on the road and wiggled, bringing traffic to a halt before they were moved on by police.

"We take roads because Extinction Rebellion will continue a campaign of mass civil-disobedience led by everyday people until we experience real change led by real democracy," Rachel said.

"Other tactics, such as petitioning, door knocking, going to marches and voting are not working for us in a system where the fossil fuel industry provide the largest source of political donations to both major parties.

"Our government is compromised and deadlocked."

…and the zombies have come to get them!

The Zombies of the Climate ApoCOALpse have today swarmed around Queensland’s Parliament House this morning to highlight impending climate chaos.

XR spokesperson Rachel says the Zombies represented undead billionaires, workers, scientists. ‘Everyday people have come back from the future to warn of the environmental perils of inaction during this crisis.’

The group chased politicians around gates to block and disrupt their personal and car entry to the building and swamping them with climate zombies as they went past.

Just after 8.35am (QLD time) people breached the gates of Parliament House briefly before they were ushered out by police and security.

‘The Queensland government has failed to take any meaningful action on the climate crisis that we are facing. They have yet to declare a climate emergency. They continue to invest in destructive industries and prioritise profit over people, the COVID-19 gas led recovery plan if just one recent devastating example of that,’ says Rachel.

The spectacle of zombies lurching around the streets in gruesome blood soaked costumes, depicting an apocalyptic scene of destruction and devastation sent a strong message to politicians. The activists are portraying a future of immense human suffering if we continue to sleepwalk to catastrophe.
The message is act now

The message is: If we don’t act now there will be fires and floods, food and water shortages, mass displacement of people across the world, global health crises and irreversible loss of biodiversity.

At 8.42am the group took the road outside Parliament House at the intersection of Alice and George St, for just under 10 minutes before police threatened to move in an arrest the crowd. Traffic was at a standstill and choked up quickly in the busy peak-hour as the swarm of zombies spilt out on to the road to do the Zombie Dance, a booming rendition of Michael Jackson’s Thriller.

‘We take roads because Extinction Rebellion will continue a campaign of mass civil-disobedience led by everyday people until we experience real change led by real democracy. Other tactics, such as petitioning, door knocking, going to marches and voting are not working for us in a system where the fossil fuel industry provide the largest source of political donations to both major parties. Our government is compromised and deadlocked,’ said Rachel.
There is still time

‘There is still time, if politicians act in the interests of the people – 75% of the population want urgent action on managing the climate crisis.’

Amy MacMahon, MP for the Greens, was the only politician seen to engage with the protestors. She came out filming the protest, and when Zombies told her they were hear to warn politicians, to tell them to listen to the climate science, because they weren’t she agreed: ‘That’s exactly right,’ she said. ‘Most people in there aren’t listing to the people and climate science, and we’ve got politicians inside here who are still defending coal on a daily basis.’

XR are demanding that decision-making on the climate and ecological crisis be led by a binding Citizen’s Assembly – informed by scientific fact, First Nations knowledge of ecosystems care, climate justice advocates and other knowledge holders – in order to formulate a plan so we can halt biodiversity loss and reach net-zero emissions by 2025.

More than $165,000 has been raised for a single mum who was arrested after leaving her children in a motel room so she could go to work.

A GoFundMe page was set up in support of 24-year-old Shaina Bell, of Liberty Township, Ohio, after she was arrested last week and charged with two counts of misdemeanour child endangerment.

Bell told police she usually asks someone to check on her children every hour while she works, and she felt her elder daughter, who is 10, was old enough to stay with her two-year-old sister at the Motel 6 room where they live while she went to work down the street at a Little Caesars fast food restaurant.

The GoFundMe page aims to help Bell find permanent housing, and after members of the public heard her story hundreds of people came forward to donat
At the time of writing, February 22, the fundraiser has now received more than $165,000 in donations from generous strangers looking to help.



Speaking to WKBN, per Fox 5 News, Bell explained that while people are ‘being there for [her] and showing great support,’ she has also been the target of some hurtful comments.

She continued:

I have over $100,000 in a GoFundMe account right now. I didn’t ask for that, but people gave it to me, and I’m just over appreciative to what’s going on.


Bell was released the day after she was arrested, and she has expressed her hopes to use the money raised through GoFundMe to buy a house for herself and her family.

What's in your baby's food? 
Probably dangerous heavy metals like arsenic, lead, mercury.

We assume that companies that make baby foods and baby products want the best for our children. Their own data proves those assumptions wrong.

Raja Krishnamoorthi
Opinion contributor

We assume that anything with “baby” on the label must be safe, gentle and wholesome. Surely companies making baby foods would not knowingly sell products with dangerous levels of toxins, right? The Food and Drug Administration must be checking?

Unfortunately, those assumptions are wrong.

Over the last year, I have been investigating baby food safety by looking at the test results possessed by the manufacturers themselves. What I learned was alarming.

Common baby foods found in grocery stores — made by trusted brands such as HappyBABY (Nurture, Inc.), Earth’s Best Organic (Hain Celestial Group, Inc.), Beech-Nut, and Gerber — contain dangerously high levels of toxic heavy metals like arsenic, lead, cadmium and mercury.

Heavy metals in baby food

Toxic heavy metals are exceptionally harmful to babies’ brains. Exposure can lead to long-term brain damage, causing decreased academic achievement, lost IQ points, learning disabilities, and behavioral disabilities. Babies’ developing brains are at a much higher risk than adults, since babies are small, have other developing organ systems, and absorb more of the heavy metals than adults. The heavy metals accumulate in the body, which means that the more a baby eats tainted baby food, the worse the negative impact on their brain development.

USA TODAY Food:Arsenic, toxic metals found in baby food including Walmart, Gerber, Beech-Nut brands, according to new report

Right now, there are very few federal standards limiting the amount of heavy metals in baby food, and there is no requirement for the companies to tell us how much their products contain. But we do know that many baby foods contain much higher levels of heavy metals than products for which federal standards exist. Bottled water, for instance, may contain no more than 10 parts per billion of inorganic arsenic. In just one disturbing example that I found, apple and broccoli puffs were sold with a lead content of 180 parts per billion. Remember, the company’s own testing proved it.

In the absence of rules, baby food makers have made up their own proprietary standards. But the companies set them dangerously high, often at or above 100 parts per billion of the dangerous metals. And even then, my investigation found that the companies ignore them. If their product contains higher levels of toxic heavy metals than their proprietary standards allow, they sell them anyway. The manufacturer of HappyBABY explained to me that their testing is only intended to monitor their suppliers, not to protect babies. So, “all of the products that were tested were sold into commerce.”

Parents who seek out organic options for their babies will also be disappointed to learn that organic baby foods are just as dangerous as conventional foods in terms of heavy metal content in their foods. 

What else is there to hide?


As concerning as all of this is, there are three companies that could be even worse. Walmart (seller of Parent’s Choice), Sprout Organic Foods, and Campbell (seller of Plum Organics) refused to provide their testing results as part of our congressional investigation. Our investigative body is greatly concerned that their lack of cooperation might obscure the presence of even higher levels of heavy metals in their baby foods, compared to their competitors’ products. Parents beware.

As chairman of the House Oversight Economic and Consumer Policy Subcommittee, I have investigated my share of bad acts by corporations. I find none more disconcerting than companies that make profits by putting our children’s health at risk.

I uncovered that e-cigarette maker, JUUL, was targeting kids as young as eight years old by sponsoring their summer camps. I discovered that the manufacturers of booster seats were falsely advertising their products for children too small to safely use them, putting them at risk of serious injury. However, the bad behavior of baby food manufacturers may take the cake.

Parents confront many unavoidable worries, but the safety of the baby food they give their children should not be one of them. I hope that HappyBABY, Earth’s Best Organic, Beech-Nut, Gerber, Walmart (seller of Parent’s Choice), Sprout Organic Foods and Campbell (seller of Plum Organics) take this opportunity to make their products safer. Just in case they dither, I will introduce legislation that will require them to make their products safe.

Rep. Raja Krishnamoorthi, D-Ill., is chair of the Subcommittee on Economic and Consumer Policy, housed under the House Committee on Oversight and Reform.


The Melting of Large Icebergs is a Key Stage in the Evolution of Ice Ages



A new study, in which the Andalusian Earth Sciences Institute (IACT) (CSIC-UGR) participated, has described for the first time a key stage in the beginning of the great glaciations and indicates that it can happen to our planet in the future.

The study claims to have found a new connection that could explain the beginning of the ice ages on Earth

Antarctic iceberg melt could hold the key to the activation of a series of mechanisms that cause the Earth to suffer prolonged periods of global cooling, according to Francisco J. Jiménez-Espejo, a researcher at the Andalusian Earth Sciences Institute (CSIC-UGR), whose discoveries were recently published in the prestigious journal Nature.

It has long been known that changes in the Earth’s orbit, as it moves around the Sun, trigger the beginning or end of glacial periods by affecting the amount of solar radiation that reaches the planet’s surface. However, until now, the question of how small variations in the solar energy that reaches us can lead to such dramatic shifts in the planet’s climate has remained a mystery.

In this new study, a multinational group of researchers proposes that, when the Earth’s orbit around the sun is just right, the Antarctic icebergs begin to melt further and further away from the continent, moving huge volumes of freshwater from the Antarctic Ocean into the Atlantic.

This process causes the Antarctic Ocean to become increasingly salty, while the Atlantic Ocean becomes fresher, affecting overall ocean circulation patterns, drawing CO2 from the atmosphere and reducing the so-called greenhouse effect. These are the initial stages that mark the beginning of an ice age on the planet.

Within this study, the scientists used several techniques to reconstruct oceanic conditions in the past, including by identifying tiny fragments of rock that had broken away from Antarctic icebergs as they melted into the ocean. These deposits were obtained from marine sediment cores recovered by the International Ocean Discovery Program (IODP) during Expedition 361 off the sea-margins of South Africa. These sediment cores enabled the scientists to reconstruct the history of the icebergs that reached these latitudes in the last million and a half years, this being one of the most continuous records known.

Climate simulations


The study describes how these rocky deposits appear to be consistently associated with variations in deep ocean circulation, which was reconstructed from chemical variations in minute deep-sea fossils known as foraminifera. The team also used new climate simulations to test the proposed hypotheses, finding that huge volumes of fresh water are carried northward by icebergs.

The first author of the article, PhD student Aidan Starr from the University of Cardiff, notes that the researchers are “surprised to have discovered that this teleconnection is present in each of the different ice ages of the last 1.6 million years. This indicates that the Antarctic Ocean plays a major role in the global climate, something that scientists have long sensed, but that we have now clearly demonstrated.”

Francisco J. Jiménez Espejo, a researcher with the IACT, participated in his capacity as a specialist in inorganic geochemistry and physical properties during the IODP 361 expedition aboard the JOIDES Resolution research vessel. For two months, between January and March 2016, the research team sailed between Mauritius and Cape Town, collecting deep-sea sediment cores.

Jiménez Espejo’s main contribution to the study focused on identifying the geochemical variations associated with glacial and interglacial periods, which has made it possible to estimate with greater accuracy the age of the sediment and its sensitivity to the different environmental changes associated with those periods.

Over the course of the last 3 million years, the Earth began to experience periodic glacial cooling. During the most recent episode, about 20,000 years ago, icebergs continuously reached the Atlantic coasts of the Iberian Peninsula from the Arctic. Currently, the Earth is in a warm interglacial period known as the Holocene.

However, the progressive increase in global temperature associated with CO2 emissions from industrial activities could affect the natural rhythm of glacial cycles. Ultimately, the Antarctic Ocean could become too warm for Antarctic icebergs to be able to carry freshwater north, and therefore a fundamental stage in the beginning of the ice ages–the variations in thermohaline circulation–would not take place.

Ian Hall, also of Cardiff University, who co-directed the scientific expedition, indicates that the results may contribute to understanding how the Earth’s climate may respond to anthropic changes. Similarly, Jiménez Espejo, notes that “last year, during an expedition aboard Hespérides, the Spanish Navy research vessel, we were able to observe the immense A-68 iceberg that had just broken into several pieces next to the islands of South Georgia. Ocean warming may cause the trajectories and the melt patterns of these large icebergs to alter in the future, affecting the currents and, therefore, our climate and the validity of the models that scientists use to predict it.”

This First-Ever VIDEO of a Rover Landing on Mars Will Leave You Speechless


(NASA/JPL-Caltech)
SPACE



RAFI LETZTER, LIVE SCIENCE
22 FEBRUARY 2021

For the first time ever, you can watch a rover landing on Mars. And it's epic on many levels.

Human beings have been dropping machines on Mars since the 1970s: landers that parachuted to the surface, rovers that were destroyed during landing, and later rovers that survived their landings inside giant, bouncing cushions of airbags.

Now powerful skycranes lower NASA rovers to the surface. But in all that time, all those spectacular successes and failures have taken place out of sight on another world. That changed with Perseverance.

NASA outfitted the Perseverance rover and its landing vehicle, which arrived on the Red Planet Feb. 18, with a collection of high-quality, high-speed video cameras to capture the 'seven minutes of terror', as engineers refer to the plunge to the Martian surface.

The cameras were set up to offer viewers front-row seats to the final two chapters of the trucklike machine's plunge from solar orbit onto the Martian dirt: the parachute and the skycrane.

As Live Science previously reported, some tricky maneuvering is required to deposit a 10-foot-long (3.1 meter), 2,260-pound (1,025 kilograms) nuclear-powered robot gently within a narrow target on the dangerous, rough surface of another planet.

The video shows the rover's landing vehicle popping off its heat shield so it can "see" the ground during landing to time its parachute deployment. The metal disk falls away, revealing the long drop that still separates the US$2.7 billion, nuclear-powered rover from the ground.



Another camera shows the parachute unfurling, a sheet of fabric tasked with slowing the descent from 940 mph (1,512 km/h) to 190 mph (306 km/h) in two minutes.

Then, the lander drops away from the parachute the robotic pilot took on its toughest challenge: Identifying and maneuvering toward a safe landing site. Finally, the skycrane hovers 65 feet (20 meters) above the Martian surface, kicking up a dust storm as it lowers a gently swaying rover on long cables to the ground before flying away.

None of the video was available to NASA during the entirely robot-controlled landing. (Getting data from Mars takes time, and the uplink bandwidth is far short of streaming speed - though NASA did manage to haul 30 gigabytes of media across interplanetary space in a few days.)

But Perseverance uploaded the material over the weekend in time for NASA to release it Monday (Feb. 22).

NASA said that the video will offer important data that will help future missions and confirmed that just about every stage of the descent went as expected and planned. The closest thing to a problem visible on the video: an apparently harmless loose spring on the back of the heat shield, visible as the protective shroud drops away from the lander.

NASA also released the first sounds recorded with a microphone on Mars.

Extremist Brains Perform Poorly at Complex Mental Tasks, Study Reveals

People with extremist views aren't only identified by their political, religious, or social beliefs, according to new research.

Those ideological convictions run deep, scientists say – so deep, in fact, that they can be recognised in a 'psychological signature' of cognitive traits and aptitudes that typifies the thinking patterns of the extremist mind.

"There appear to be hidden similarities in the minds of those most willing to take extreme measures to support their ideological doctrines," explains psychologist Leor Zmigrod from the University of Cambridge.

"This psychological signature is novel and should inspire further research on the effect of dogmatism on perceptual decision-making processes," she and colleagues write in their newly published study.

Moreover, it's possible those psychological patterns could be what compels some individuals to adopt strong or radical ideological positions in the first instance, the researchers suggest.

"Subtle difficulties with complex mental processing may subconsciously push people towards extreme doctrines that provide clearer, more defined explanations of the world, making them susceptible to toxic forms of dogmatic and authoritarian ideologies," Zmigrod says.

In the new study, Zmigrod and fellow researchers ran an experiment with 334 participants, who provided demographic information and filled out a series of ideological questionnaires about their personal beliefs, including political, social, and religious beliefs.

In a previous, unrelated study involving the same group of people, the participants had performed an extensive set of 'brain games' tests – cognitive and behavioural tasks on a computer, designed to test things like their working memory, information processing, learning, and mindfulness, among others.

When Zmigrod ran the results from the ideological questionnaires against the cognitive tests, she made a surprising discovery.

"We found that individuals with extremist attitudes tended to perform poorly on complex mental tasks," she explains in The Conversation.

"They struggled to complete psychological tests that require intricate mental steps."

Specifically, those with extremist attitudes – such as endorsing violence against specific groups in society – showed poorer working memory, slower perceptual strategies, and impulsive, sensation-seeking tendencies.

However, the tests didn't only spotlight the traits of extremist thinking – other kinds of ideological beliefs also revealed the shape of their psychological signatures.

Participants who showed dogmatic thinking were slower to accumulate evidence in speeded decision-making tasks, the researchers found, but were also more impulsive and prone to taking ethical risks.

Individuals who were politically conservative showed reduced strategic information processing, heightened response caution in perceptual decision-making paradigms, and displayed an aversion to social risk-taking.

In contrast, participants with liberal beliefs were more likely to adopt faster and less precise perceptual strategies, displaying less caution in cognitive tasks.

Similarly to the conservative group, people with religious views reflected heightened caution and reduced strategic information processing in the cognitive domain, along with enhanced agreeableness, risk perception and aversion to social risk-taking.

"Our research shows our brains hold clues – subtle metaphors, perhaps – for the ideologies we choose to live by and the beliefs we rigidly stick to," Zmigrod explains.

"If our mind tends to react to stimuli with caution, it may also be attracted by cautious and conservative ideologies. If we struggle to process and plan complex action sequences, we may be drawn to more extreme ideologies that simplify the world and our role within it."

Of course, the results here are open to a fair degree of interpretation, and there are limitations to what relatively small psychological studies like this can tell us without further replication involving larger samples.

Nonetheless, the methodology here could lay the groundwork for future psychological tests that may be able to identify individuals at risk of radicalisation and adopting extremist beliefs – as well as suggesting what kind of thinking shields others from the same.

"The [analysis] reveals the ways in which perceptual decision-making strategies can percolate into high-level ideological beliefs, suggesting that a dissection of the cognitive anatomy of ideologies is a productive and illuminating endeavour," the authors write in their study.

"It elucidates both the cognitive vulnerabilities to toxic ideologies as well as the traits that make individuals more intellectually humble, receptive to evidence and ultimately resilient to extremist rhetoric."

The findings are reported in Philosophical Transactions of the Royal Society B.
