American inquisition: Training teachers to extract confessions from their students

decay14bw

Douglas Starr writes: About a year and a half ago, Jessica Schneider was handed a flyer by one of her colleagues in the child-advocacy community. It advertised a training session, offered under the auspices of the Illinois Principals Association (I.P.A.), in how to interrogate students. Specifically, teachers and school administrators would be taught an abbreviated version of the Reid Technique, which is used across the country by police officers, private-security personnel, insurance-fraud investigators, and other people for whom getting at the truth is part of the job. Schneider, who is a staff attorney at the Chicago Lawyers’ Committee for Civil Rights Under Law, was alarmed. She knew that some psychologists and jurists have characterized the technique as coercive and liable to produce false confessions — especially when used with juveniles, who are highly suggestible. When she expressed her concerns to Brian Schwartz, the I.P.A.’s general counsel, he said that the association had been offering Reid training for many years and found it both popular and benign. To prove it, he invited Schneider to attend a session in January of 2015.

The training was led by Joseph Buckley, the president of John E. Reid and Associates, which is based in Chicago. Like the adult version of the Reid Technique, the school version involves three basic parts: an investigative component, in which you gather evidence; a behavioral analysis, in which you interview a suspect to determine whether he or she is lying; and a nine-step interrogation, a nonviolent but psychologically rigorous process that is designed, according to Reid’s workbook, “to obtain an admission of guilt.” Most of the I.P.A. session, Schneider told me, focussed on behavioral analysis. Buckley described to trainees how patterns of body language — including slumping, failing to look directly at the interviewer, offering “evasive” responses, and showing generally “guarded” behaviors — could supposedly reveal whether a suspect was lying. (Some of the cues were downright mythological — like, for instance, the idea that individuals look left when recalling the truth and right when trying to fabricate.) Several times during the session, Buckley showed videos of interrogations involving serious crimes, such as murder, theft, and rape. None of the videos portrayed young people being questioned for typical school misbehavior, nor did any of the Reid teaching materials refer to “students” or “kids.” They were always “suspects” or “subjects.”

Laura Nirider, a professor of law at Northwestern University and the project director of the Center on Wrongful Convictions of Youth, attended the same session as Schneider. She told me that about sixty people were there. “Everybody was on the edge of their seat: ‘So this is how we can learn to get the drop on little Billy for writing graffiti on the underside of the lunchroom table,’” she said. One vice-principal told Nirider that the first thing he does when he interrogates students is take away their cell phones, “so they can’t call their mothers.” [Continue reading…]

Human influence on the planet is so profound – and terrifying – it will leave its legacy for millennia

decay1

Robert Macfarlane writes: In 2003 the Australian philosopher Glenn Albrecht coined the term solastalgia to mean a “form of psychic or existential distress caused by environmental change”. Albrecht was studying the effects of long-term drought and large-scale mining activity on communities in New South Wales, when he realised that no word existed to describe the unhappiness of people whose landscapes were being transformed about them by forces beyond their control. He proposed his new term to describe this distinctive kind of homesickness.

Where the pain of nostalgia arises from moving away, the pain of solastalgia arises from staying put. Where the pain of nostalgia can be mitigated by return, the pain of solastalgia tends to be irreversible. Solastalgia is not a malady specific to the present – we might think of John Clare as a solastalgic poet, witnessing his native Northamptonshire countryside disrupted by enclosure in the 1810s – but it has flourished recently. “A worldwide increase in ecosystem distress syndromes,” wrote Albrecht, is “matched by a corresponding increase in human distress syndromes”. Solastalgia speaks of a modern uncanny, in which a familiar place is rendered unrecognisable by climate change or corporate action: the home become suddenly unhomely around its inhabitants.

Albrecht’s coinage is part of an emerging lexis for what we are increasingly calling the “Anthropocene”: the new epoch of geological time in which human activity is considered such a powerful influence on the environment, climate and ecology of the planet that it will leave a long-term signature in the strata record. And what a signature it will be. We have bored 50m kilometres of holes in our search for oil. We remove mountain tops to get at the coal they contain. The oceans dance with billions of tiny plastic beads. Weaponry tests have dispersed artificial radionuclides globally. The burning of rainforests for monoculture production sends out killing smog-palls that settle into the sediment across entire countries. We have become titanic geological agents, our legacy legible for millennia to come. [Continue reading…]

Junk food is bad for plants, too

Anne Biklé and David R. Montgomery write: Most of us are familiar with the much-maligned Western diet and its mainstay of processed food products found in the middle aisles of the grocery store. Some of us beeline for the salty chips and others for the sugar-packed cereals. But we are not the only ones eating junk food. An awful lot of crops grown in the developed world eat a botanical version of this diet—main courses of conventional fertilizers with pesticide sides.

It’s undeniable that crops raised on fertilizers have produced historical yields. After all, the key ingredients of most fertilizers — nitrogen (N), phosphorus (P), and potassium (K) — make plants grow faster and bigger. And popular insecticides and herbicides knock back plant enemies. From 1960 to 2000, a time when the world’s population doubled, global grain production rose even more quickly. It tripled.

But there is a trade-off. High-yielding crops raised on a steady diet of fertilizers appear to have lower levels of certain minerals and nutrients. The diet our crops eat influences what gets into our food, and what we get — or don’t get — out of these foods when we eat them. [Continue reading…]

Technology, the faux equalizer

structure3

Adrienne LaFrance writes: Just over a century ago, an electric company in Minnesota took out a full-page newspaper advertisement and listed 1,000 uses for electricity.

Bakers could get ice-cream freezers and waffle irons! Hat makers could put up electric signs! Paper-box manufacturers could use glue pots and fans! Then there were the at-home uses: decorative lights, corn poppers, curling irons, foot warmers, massage machines, carpet sweepers, sewing machines, and milk warmers all made the list. “Make electricity cut your housework in two,” the advertisement said.

This has long been the promise of new technology: That it will make your work easier, which will make your life better. The idea is that the arc of technology bends toward social progress. This is practically the mantra of Silicon Valley, so it’s not surprising that Google’s CEO, Sundar Pichai, seems similarly teleological in his views. [Continue reading…]

Why ‘natural selection’ became Darwin’s fittest metaphor

lichen7

Kensy Cooperrider writes: ome metaphors end up forgotten by all but the most dedicated historians, while others lead long, productive lives. It’s only a select few, though, that become so entwined with how we understand the world that we barely even recognize them as metaphors, seeing them instead as something real. Of course, why some fizzle and others flourish can be tricky to account for, but their career in science provides some clues.

Metaphors, as we all by now know, aren’t just ornamental linguistic flourishes — they’re basic building blocks of everyday reasoning. And they’re at their most potent when they recast a difficult-to-understand phenomenon as something familiar: The brain becomes a computer; the atom, a tiny solar system; space-time, a fabric. Metaphors that tap into something familiar are the ones that generally gain traction.

Charles Darwin gave us both kinds, big winners and total flops. Natural selection, his best-known metaphor, is still a fixture of evolutionary biology. Though it’s not always recognized as a metaphor today, that’s exactly what it was to Darwin and his contemporaries. After all, evolution was a foreign and unwieldy concept. So Darwin set out to make it accessible by comparing it to a method employed in farmyards around the world.

For years, Darwin — a fancy pigeon breeder — obsessed over what he called artificial selection, what cattle-breeders, gardeners, and crop-growers did to create new varieties of plant and animal: allowing just the ones with desirable traits to reproduce. Darwin’s first-hand experience with breeding set the stage for his now-famous metaphoric leap. [Continue reading…]

‘Hobbits’ may have died out before the arrival of humans

Science News reports: Hobbits disappeared from their island home nearly 40,000 years earlier than previously thought, new evidence suggests.

This revised timeline doesn’t erase uncertainty about the evolutionary origins of these controversial Indonesian hominids. Nor will the new evidence resolve a dispute about whether hobbits represent a new species, Homo floresiensis, or were small-bodied Homo sapiens.

Hobbits vanished about 50,000 years ago at Liang Bua Cave on Flores, an island situated between Borneo and Australia’s northern coast, say archaeologist Thomas Sutikna of the University of Wollongong, Australia, and his colleagues.

Cave sediment dating to about 12,000 years ago, which lies just above soil that yielded H. floresiensis remains, provided an initial estimate of when these diminutive hominids with chimp-sized brains died out. But that sediment washed into the cave long after H. floresiensis was gone, covering much older, hobbit-bearing soil, the researchers report in the March 31 Nature. [Continue reading…]

Islam’s forgotten bohemians

Nile Green writes: Every year, thousands of festivals around the tombs of Sufi saints in India, Pakistan and Bangladesh demonstrate the vitality of Sufi poetry. Dotted throughout town and countryside, the shrines where these saints are buried still form the focus for the spiritual lives of tens of millions of Muslims. Their doors and rituals are open to people of any religious background; as a result, Sufi shrines in India still play an important role in the religious life of many Hindus and Sikhs. The work of the great Baba Farid, a 13th-century Punjab Sufi poet, also exemplifies this long history of religious co-existence, as his poems form the oldest parts of the Sikh scriptures.

Farid’s poems are still recited in Sikh temples around the world. In one of the verses from his Adi Granth (the sacred scripture or ‘First Book’ of Sikhism), Farid declares in rustic and homely Punjabi:

Ap li-ay lar la-ay dar darves say.

Translation: Those tied to Truth’s robe are true tramps on the doorstep.

The seeker after Truth must become a wandering beggar. The word Farid uses is darves, or ‘dervish’ – literally, a vagrant who goes from door to door. Read again that alliterative line of Punjabi: Ap li-ay lar la-ay dar darves say. It has the simple rhythm of repetition, the call of love’s beggar traipsing from house to house.

What the German philosopher Max Weber described as the disenchantment of the world, modernity’s discrediting of the supernatural and magical, has not been good for these beggars, these mystical troubadours, especially among the Muslim middle classes. Their pilgrimage places, however, retain mass appeal, especially among the large populations of poor and uneducated people. That is why fundamentalists, whether the Pakistani Taliban, the Saudi government or ISIS, have destroyed so many Sufi shrines and places of pilgrimage. The poetry sung at those places celebrates and advances an Islam that rejects political power, an Islam incompatible with the ambitions of religious fundamentalism. It is an Islam antithetical to political Islam, which sees political power as the foundation of religion. Although not all forms of Sufi Islam are non-political, the Sufism of the dervishes renounced political power as the most significant impediment on the long road to their divine beloved. It is a spirit of Islam still very much alive. [Continue reading…]

An American in Istanbul: Molly Crabapple on art and activism

Pacific Standard: “To draw is to objectify, to go momentarily to a place where aesthetics mean more than morality,” Molly Crabapple writes in her memoir, Drawing Blood, an addictive volume that I devoured a few weeks ago during a flight from Rome to Istanbul, the city that stands at the center of Crabapple’s fascination with what was once called “the Orient.” With her artwork already placed in the permanent collection of the Museum of Modern Art, her essays and illustrations published in venues like Vanity Fair and Vice, the 33-year-old artist is a curious composite of entrepreneur, revolutionary, and bohemian artist. The book is an account of Crabapple’s formation as an artist and political dissident, from her childhood in Long Island to teenage travels in Europe and the Middle East, to her mature return to New York in the heart of Occupy protests at Zuccotti Park.

Drawing Blood is designed as a notebook, where Crabapple sketches her life story in both words and lines — 30 short chapters featuring snappy episodes from the artist’s life crammed together with illustrations done in the style of a courtroom sketch. The book’s central characters and places, meanwhile — a group of intellectuals, artists, sex workers, refugees, dissidents, bookstores, and streets who have helped shape Crabapple’s conscience — come to life in the book’s sketches, wherein Crabapple seems to have painted each at the moment she first came into contact with them.

Why science and religion aren’t as opposed as you might think

By Stephen Jones, Newman University and Carola Leicht, University of Kent

The debate about science and religion is usually viewed as a competition between worldviews. Differing opinions on whether the two subjects can comfortably co-exist – even among scientists – are pitted against each other in a battle for supremacy.

For some, like the late paleontologist Stephen Jay Gould, science and religion represent two separate areas of enquiry, asking and answering different questions without overlap. Others, such as the biologist Richard Dawkins – and perhaps the majority of the public – see the two as fundamentally opposed belief systems.

But another way to look at the subject is to consider why people believe what they do. When we do this, we discover that the supposed conflict between science and religion is nowhere near as clear cut as some might assume.

Slaughter at the bridge: Uncovering a colossal Bronze Age battle

Andrew Curry reports: About 3200 years ago, two armies clashed at a river crossing near the Baltic Sea. The confrontation can’t be found in any history books — the written word didn’t become common in these parts for another 2000 years — but this was no skirmish between local clans. Thousands of warriors came together in a brutal struggle, perhaps fought on a single day, using weapons crafted from wood, flint, and bronze, a metal that was then the height of military technology.

Struggling to find solid footing on the banks of the Tollense River, a narrow ribbon of water that flows through the marshes of northern Germany toward the Baltic Sea, the armies fought hand-to-hand, maiming and killing with war clubs, spears, swords, and knives. Bronze- and flint-tipped arrows were loosed at close range, piercing skulls and lodging deep into the bones of young men. Horses belonging to high-ranking warriors crumpled into the muck, fatally speared. Not everyone stood their ground in the melee: Some warriors broke and ran, and were struck down from behind.

When the fighting was through, hundreds lay dead, littering the swampy valley. Some bodies were stripped of their valuables and left bobbing in shallow ponds; others sank to the bottom, protected from plundering by a meter or two of water. Peat slowly settled over the bones. Within centuries, the entire battle was forgotten. [Continue reading…]

The microbes that make us who we are

microbiome

Most people, however strongly they might hold to what they regard as a scientific view of life — that we are biological organisms, products of evolution, not destined for a supernatural afterlife — nevertheless most likely have a sense of identity that does not easily accommodate the idea that our thoughts and feelings are influenced by bacteria. Indeed, such an idea might sound delusional.

Yet this is what is increasingly clearly understood: that the body is not the abode of an elusive self; nor that human experience can be reduced to the aggregation of cascades of action potentials producing a neural symphony; but that this seemingly unitary being is in fact a community in which what we are and what lives inside our body cannot be separated.

Science magazine reports: The 22 men took the same pill for four weeks. When interviewed, they said they felt less daily stress and their memories were sharper. The brain benefits were subtle, but the results, reported at last year’s annual meeting of the Society for Neuroscience, got attention. That’s because the pills were not a precise chemical formula synthesized by the pharmaceutical industry.

The capsules were brimming with bacteria.

In the ultimate PR turnaround, once-dreaded bacteria are being welcomed as health heroes. People gobble them up in probiotic yogurts, swallow pills packed with billions of bugs and recoil from hand sanitizers. Helping us nurture the microbial gardens in and on our bodies has become big business, judging by grocery store shelves.

These bacteria are possibly working at more than just keeping our bodies healthy: They may be changing our minds. Recent studies have begun turning up tantalizing hints about how the bacteria living in the gut can alter the way the brain works. These findings raise a question with profound implications for mental health: Can we soothe our brains by cultivating our bacteria?

By tinkering with the gut’s bacterial residents, scientists have changed the behavior of lab animals and small numbers of people. Microbial meddling has turned anxious mice bold and shy mice social. Rats inoculated with bacteria from depressed people develop signs of depression themselves. And small studies of people suggest that eating specific kinds of bacteria may change brain activity and ease anxiety. Because gut bacteria can make the very chemicals that brain cells use to communicate, the idea makes a certain amount of sense.

Though preliminary, such results suggest that the right bacteria in your gut could brighten mood and perhaps even combat pernicious mental disorders including anxiety and depression. The wrong microbes, however, might lead in a darker direction.

This perspective might sound a little too much like our minds are being controlled by our bacterial overlords. But consider this: Microbes have been with us since even before we were humans. Human and bacterial cells evolved together, like a pair of entwined trees, growing and adapting into a (mostly) harmonious ecosystem.

Our microbes (known collectively as the microbiome) are “so innate in who we are,” says gastroenterologist Kirsten Tillisch of UCLA. It’s easy to imagine that “they’re controlling us, or we’re controlling them.” But it’s becoming increasingly clear that no one is in charge. Instead, “it’s a conversation that our bodies are having with our microbiome,” Tillisch says. [Continue reading…]

Dramatic change in the moon’s tilt may help us trace the origin of water on Earth

By Mahesh Anand, The Open University

Astronomers have found evidence that the axis that the moon spins around shifted billions of years ago due to changes in the moon’s internal structure. The research could help explain the strange distribution of water ice near the lunar poles – the tilt would have caused some of the ice to melt by suddenly exposing it to the sun while shadowing other areas. It could also help us pinpoint craters that have been shadowed for so long that they contain water ice from early in the solar system.

Identifying recent and ancient water ice in specific craters will help scientists map the history of water on the moon. And as the moon likely formed from the Earth colliding with a planet 4.5 billion years ago, it may also help explain how the Earth got its water – a longstanding puzzle.

Are we to be a nation of such barbarous temper?

The Guardian reports: The last surviving play script handwritten by William Shakespeare, in which he imagines Sir Thomas More making an impassioned plea for the humane treatment of refugees, is to be made available online by the British Library.

The manuscript is one of 300 newly digitised treasures shining a light on the wider society and culture that helped shape Shakespeare’s imagination. All will be available to view on a new website before an extensive exhibition on the playwright at the library next month.

The Book of Sir Thomas More script is particularly poignant given the current European migration crisis.

The powerful scene, featuring More challenging anti-immigration rioters in London, was written at a time when there were heightened tensions over the number of French Protestants (Huguenots) seeking asylum in the capital.

“It is a really stirring piece of rhetoric,” said the library’s curator, Zoe Wilcox. “At its heart it is really about empathy. More is calling on the crowds to empathise with the immigrants or strangers as they are called in the text. He is asking them to imagine what it would be like if they went to Europe, if they went to Spain or Portugal, they would then be strangers. He is pleading with them against what he calls their ‘mountainous inhumanity’.

“It is striking and sad just how relevant it seems to us now considering what is happening in Europe.” [Continue reading…]

You’ll put down strangers,
Kill them, cut their throats, possess their houses,
And lead the majesty of law in line,
To slip him like a hound. Say now the king
(As he is clement, if th’ offender mourn)
Should so much come to short of your great trespass
As but to banish you, whether would you go?
What country, by the nature of your error,
Should give you harbor? Go you to France or Flanders,
To any German province, to Spain or Portugal,
Nay, any where that not adheres to England,—
Why, you must needs be strangers. Would you be pleased
To find a nation of such barbarous temper,
That, breaking out in hideous violence,
Would not afford you an abode on earth,
Whet their detested knives against your throats,
Spurn you like dogs, and like as if that God
Owed not nor made not you, nor that the claimants
Were not all appropriate to your comforts,
But chartered unto them, what would you think
To be thus used? This is the strangers’ case;
And this your mountanish inhumanity. [Source]

Refugees and riots in Shakespeare’s England

By Andrew Hadfield, University of Sussex

How many refugees should a country take? Between 1535 and 1550 citizenship was granted to 5,000 Flemish and Walloon refugees from the Low Countries to settle in Britain. They were fleeing the wars of religion that ravaged Europe throughout the 16th and 17th centuries after Martin Luther’s 1517 demand for reformation of the church.

Henry VIII, a monarch not normally known for his open-minded tolerance, started the process, and welcomed Protestant refugees after his break with Rome. The king of Spain, Charles V, Henry’s principal ally and niece of his queen, Catherine of Aragon, was outraged but Henry stuck to his principles and continued to grant religious asylum. The population of England in 1517 was around 3m people; today it is more than 53m. David Cameron has pledged that Britain will take 20,000 Syrian refugees by 2020, a considerably smaller figure in real terms than Henry managed 500 years ago.

There was sometimes ill feeling towards foreigners. The most significant outbreak of xenophobia was the “Evil May Day” riot of 1517. Angered by the presence of wealthy German merchants in London, a mob of more than a thousand gathered in Cheapside, attacking foreigners and freeing prisoners convicted of rioting. They refused to listen to the pleas of the under-sheriff of London, Thomas More, but were eventually dispersed by the king’s troops. Thirteen were executed and many more would have been but for the intervention of the queen, who pleaded for mercy to spare the suffering of the wives and children of the convicted.

How language is shaped by geography

wet-rock

Susie Neilson writes: To Hawaiian speakers, vowels reign supreme. Only eight consonants exist in the language’s 13-letter alphabet, so most of its meaning is derived from oohs and aahs, ohs and eehs. One might say Hawaiian sounds a lot like the sea that surrounds it; the bulk of its words are simple and spare, flowing smoothly from vowel to vowel. Mahalo.

On the opposite end of the spectrum, we have German. With its 30-letter alphabet, clipped consonants, and “uvulars”—sounds made by constricting the tongue against the back wall of the throat—German is famously harsh and guttural. Auf Wiedehrsen! One might say — if one weren’t German, that is — that the language is cold and craggy, just like the country.

What accounts for how discrepant these languages sound? Ian Maddieson, a linguist at the University of New Mexico, had a hunch that the differences were not purely coincidental. He and a colleague, Christophe Coupe, analyzed more than 600 regional dialects around the world by topography, weather, and climate. Their findings, presented last November at the 170th Meeting of the Acoustical Society of America (ASA), claimed that the variations among the dialects exhibited a phenomenon previously only seen in birdcalls and other animal noises—acoustic adaptation. Put simply, acoustic adaptation maintains that the land where a language is born is also instrumental to how it evolves. [Continue reading…]

How we forgot how to feed ourselves

Karen Coates writes: Late in January, I boarded a long-haul flight, 27 hours and 5 minutes, 9,405 miles, three connections. I packed emergency Larabars (food for quick energy), ordered gluten-free meals (a topic for discussion another day), and thought about my meeting with the king of Boti.

Boti is a small kingdom in the Indonesian state of East Nusa Tenggara on the island of Timor. Centuries ago, this region was populated by dozens of small indigenous kingdoms, but most no longer exist in this vast and multicultural republic now united under the flag of Indonesia. Still, the villagers of Boti hold tight to their traditional customs and life from the land: They weave clothes from cotton they grow, and they never wear shoes. They make dishes from coconut shells, bags from banyan roots, candles from nuts, and tools from wood.

In 2002, my husband and I trekked 6 miles through parched, deforested hills, toward the secluded village, to meet the king, who was 96 at the time. He greeted us on his front porch. There, at his home, we were served coffee alongside bananas and sweet potatoes grown on site. The bananas were plump and juicy, not at all mealy or dull. There is a complexity to the flavor of a great banana—plucked fresh—that is experienced only in the tropics, eaten at the origins. So many wonderful bananas never make it to stores in the West.

The king, Ama Nune Benu, sat on a painted wooden chair on his porch, twisting a long root into a rope, as he told us about his way of life. “We are close with the nature,” he said. City folk are not. City folk do not work the land and grow their own food, he told us. “I have 10 fingers. If I use these 10 fingers to get something to eat, I feel better.” Processed, store-bought foods are humanity’s downfall, according to the king. [Continue reading…]

Pluto defies all expectations

pluto

Space.com reports: Pluto, known for more than eight decades as just a faint, fuzzy and faraway point of light, is shaping up to be one of the most complex and diverse worlds in the solar system.

Pluto’s frigid surface varies tremendously from place to place, featuring provinces dominated by different types of ices — methane in one place, nitrogen in another and water in yet another, newly analyzed photos and measurements from NASA’s New Horizons mission reveal.

“That is unprecedented,” said New Horizons principal investigator Alan Stern, who’s based at the Southwest Research Institute in Boulder, Colorado.

“I don’t know any other place in the entirety of the outer solar system where you see anything like this,” Stern told Space.com. “The closest analogy is the Earth, where we see water-rich surfaces and rock-rich surfaces that are completely different.”

That’s just one of the new Pluto results, which are presented in a set of five New Horizons papers published online on Thursday in the journal Science. Taken together, the five studies paint the Pluto system in sharp detail, shedding new light on the dwarf planet’s composition, geology and evolution over the past 4.6 billion years.

In warm, greasy puddles, the spark of life?

Emily Singer writes: For the past 40 years, David Deamer has been obsessed with membranes. Specifically, he is fascinated by cell membranes, the fatty envelopes that encase our cells. They may seem unremarkable, but Deamer, a biochemist at the University of California, Santa Cruz, is convinced that membranes like these sparked the emergence of life. As he envisions it, they corralled the chemicals of the early Earth, serving as an incubator for the reactions that created the first biological molecules.

One of the great initial challenges in the emergence of life was for simple, common molecules to develop greater complexity. This process resulted, most notably, in the appearance of RNA, long theorized to have been the first biological molecule. RNA is a polymer — a chemical chain made up of repeating subunits — that has proved extremely difficult to make under conditions similar to those on the early Earth.

Deamer’s team has shown not only that a membrane would serve as a cocoon for this chemical metamorphosis, but that it might also actively push the process along. Membranes are made up of lipids, fatty molecules that don’t dissolve in water and can spontaneously form tiny packages. In the 1980s, Deamer showed that the ingredients for making these packages would have been readily available on the early Earth; he isolated membrane-forming compounds from the Murchison meteorite, which exploded over Australia in 1969. Later, he found that lipids can help form RNA polymers and then enclose them in a protective coating, creating a primitive cell. [Continue reading…]
