    Memoria review: A surreal and immersive journey into the human mind

    By Francesca Steele

    Jessica searches every corner of Colombia for the source of the noiseNeon
    Film
    Memoria
    Apichatpong WeerasethakulAdvertisement

    “IN THIS town, there are a lot of people who have hallucinations,” a doctor tells Jessica (Tilda Swinton) at the beginning of Memoria. Then, in a neat encapsulation of the mix of the mystical and the medicinal that runs throughout this strange and heady film, she prescribes the tranquilliser Xanax while advising her patient not to take it in case it inhibits her ability to savour the beauty of the world.
    Jessica is a British botanist in Colombia who wakes one night to a heavy thumping noise that is loud enough to set off car alarms. When it becomes apparent that no one else heard it, it sends her on a downwards spiral into anxiety. She can find no obvious source and continues to hear the noise regularly, while no one else can. Jessica travels from city to jungle to try to work out what it all means, getting caught up in deep and sometimes disturbing questions about the nature of reality.
    The film-maker himself, Apichatpong Weerasethakul, had exploding head syndrome – a rare sleep disorder in which people are woken by the sensation of an (imagined) loud noise. Yet while his experience of this strange and unexplained condition was part of the inspiration for the story, Memoria is defiantly unempirical, more interested in how something might feel than what might have caused it.
    As she investigates the strange noise, Jessica meets and befriends Agnes, an anthropologist who is examining a newly unearthed thousand-year-old skeleton of a young girl with a hole in her skull: probably “a ritual” to release evil spirits, the scientist reasons.
    She also meets a sound engineer called Hernàn, who tries to replicate the sound inside her head with a catalogue of absurd cinema sound effects like “stomach hit wearing hoodie”, while Jessica explains that it is more like “a ball of concrete hitting a metal wall surrounded by seawater” and “a rumble from the core of the Earth”.
    Hernàn puts the sound that comes closest to music with his band, and Jessica listens to it with headphones on and a wry smile. The audience cannot hear the music and it is a typically oblique move from Weerasethakul, who won the Palme d’Or at Cannes in 2010 for the equally enthralling Uncle Boonmee Who Can Recall His Past Lives.
    Memoria is Weerasethakul’s first film set outside his home nation of Thailand, and it is essentially a meditation on interconnectedness. What does the past mean to modern life? Do we carry the memory of it, and of each other, with us somehow? And when things get weird, what should we pathologise and fix and when should we just try to understand ourselves better?
    “What should we pathologise and fix and when should we just try to understand ourselves better?”
    In doing this, Memoria isn’t didactic. Weerasethakul is asking questions, not answering them, and he seems to be aware of how lofty and pretentious it may all appear. Jessica laughs when she hears that Hernàn’s band is called The Depth of Delusion Ensemble, welcome levity that creates an unusual tone, feeling at once preternatural and realistic.
    Memoria pushes people away before pulling them close. Swinton appears frail, nervy but curious. She talks carefully, urgently to Hernàn (whom later she discovers no one else has heard of), to her sister, to Agnes, but the camera always stays far away and static, shots so long, calm and still that the film envelops you instead of talking at you like most do.
    It is a considered exercise in empathy and patience, a commitment between the camera and its audience as much as between people and generations. In its second half, Jessica visits an anthropological dig at Bogotá and there she meets a different Hernàn, a man who claims to remember everything. “I try to limit what I see,” he says, “experiences are harmful.”
    As Jessica and the new Hernàn commune over coffee and pastoral meditations on life and death, memory becomes a fluid thing, a shared thing, as if we are all part of some collective experience. It is surreal and moving.
    An abrupt change of direction in the finale feels like quite a U-turn and won’t be to everybody’s tastes, but overall Memoria is measured and deeply felt. This is slow cinema to see on a big screen and get lost in.

    At your fingertips: The nail art that opens doors to the metaverse

    Feedback is our weekly column of bizarre stories, implausible advertising claims, confusing instructions and more

    Humans

    5 January 2022

    Josie Ford
    Nailed it
    Gazing into the alternative reality featured on the other pages of this magazine, we have mixed feelings. That’s a generally valid statement, but it applies especially to the metaverse that The Company Formerly Known As Facebook and others are building.
    Or it does until we realise it gives our influencer franchise a (glittery) golden opportunity to mention Metaverse Nails™ (patent pending), “the only product in the WORLD that allows you to adorn your digital and physical self with customisable holograms”. “Glam wearable tech” is very much our bag – see our tote? It’s totes virtual – although our community service order still stands after going too far with Gucci’s virtual clothing line in lockdown (3 October 2020). Collectible fashion accessories that interact with a 3D social app to trigger a dazzling range of interactive hologram nail stickers that can be snapped and shared in real time to social networks seem a safer bet.
    As was reported last year, TCFKAF might have agreed: shortly after its metamorphosis in October, it briefly suspended the Instagram account, @metaverse, of the driving force behind Metaverse Nails™ (patent pending), Thea-Mai Baumann, for “pretending to be someone else”. Far be it for us to question motivations, but if being someone else isn’t the point of the metaverse, we aren’t sure what is.Advertisement
    Flipping the bird
    Feedback is relieved to be informed by our man in a hide with a pair of binoculars, Jeff Hecht, that birds are real. For those who hadn’t realised there was any doubt, we urge you to marinate – but not for too long – in the social media conspiracy theory that birds used to be real, but were replaced by US government spy drones. The walls of the metaverse being decidedly porous, this has seen billboards pop up in major US cities and a demonstration outside Twitter’s headquarters in San Francisco demanding that the company change its logo.
    For a while, we had a similar, special theory of avian unreality concerning the implausible, yet undoubtedly ornamental, pelicans of St James’s Park in the heart of London’s government district. We gave it up on the basis we couldn’t work out who ordered the poop. Now, as The New York Times revealed last month, the general theory of unreality has been revealed as a prank dreamed up to demonstrate the absurdity of conspiracy theories.
    This is all pretty, well, meta. We are left pondering the truth value of the statement “this conspiracy theory is false”. While we do so, we offer up the fact that, although birds might exist, fish, reptiles, worms, wasps, jellyfish and a host of other things don’t. That isn’t a conspiracy, it is phylogenetics.
    Look on the buttered side
    Andy Bebington intervenes from Croydon, London, with a philosophical solution to the long-standing scientific puzzle in our Twisteddoodles cartoon on 4 December 2021: why toast always lands butter-side down. It is because we buttered the wrong side. We await explanation of how attaching buttered toast to the back of a falling cat retrocausually flips right side to wrong side. It is probably something to do with quantum theory; it usually is.
    How low can you go?
    Did monkeys really sail the oceans on floating rafts of vegetation? we asked in our super soaraway holiday edition (18/25 December 2021, p 50), answering the question with a firm “yeah but no but yeah”. Brian Horton of the floating raft of vegetation that is Tasmania takes exception, not to that, but to our description of a riverine floating island that “covered an area about the size of two Olympic swimming pools”.
    “Surely everyone knows that area is measured in football pitches and swimming pools are only for volume,” he fumes. “Please ensure that the appropriate units are used in New Scientist articles to maintain standards.”
    We hear you, Brian, while countering with Malcolm Drury of Ottawa’s clipping from a CBC News website article on oil sands tailing ponds in Alberta with a storage capacity “the equivalent volume of more than 560,000 Olympic-sized swimming pools, which would stretch from Edmonton to Melbourne, Australia, and back if placed end-to-end”. Measurement standards are clearly slipping – to lower and lower dimensions.
    In their element again
    Many thanks to those of you who responded to our appeal for elemental names from across the world (11 December 2021). Sergio Frosini from Genoa, Italy, wins the prize of a gram of unobtanium in a virtual tote bag with his list of actors Franca Rame (copper) and Turi Ferro (iron), journalist Tito Stagno (tin) and horror film director Dario Argento (silver).
    Sergio further enriches us by informing us that Stagno’s principal claim to fame is as the first person in the world to announce the Apollo 11 mission’s touchdown on the moon – a full 56 seconds before it happened. Miring ourselves briefly in the nether regions of the Italian-speaking web convinces us that those most liable to bring up this striking instance of retrocausality have well-defined views of the moon landing. Having seen the grainy footage ourselves, we are prepared to accept it was cock-up, not conspiracy. Which is a pretty good guiding principle for life, come to think of it.

    The best science books coming your way in 2022

    By Simon Ings
    If we can’t beat water, perhaps we should learn to go with the flowPete Saloutos/Getty Images
    Explore and protect
    ACROSS the globe, water went wild in 2021. Floods hit everywhere from Afghanistan to New Zealand, and the UK was affected by flash floods in the summer.
    So, as we begin 2022, we should take heed of Erica Gies’s forthcoming book Water Always Wins: Going with the flow to thrive in the age of droughts, floods and climate change. She argues that, as our fields and cities sprawl, it is high time we learned to flow with water’s natural rhythms.
    Chris Armstrong’s A Blue New Deal: Why we need a new politics for the ocean also calls for action. His priorities are the many challenges faced by those whose lives rely on the oceans. From the fate of nations being submerged by sea level rise to the exploitation of people working in fishing, plus the rights of marine animals to a future where they aren’t at risk of extinction, he points out that there is a lot to do.Advertisement
    Along with the growing urgency around climate change, there is a renewed interest in the way we tell the story of life on Earth. In The Sloth Lemur’s Song: Madagascar from the deep past to the uncertain present, environmental researcher Alison Richard traces the history of Earth’s fourth-biggest island, from its origins as a landlocked region of Gondwana to its emergence as an island home to huge, flightless birds and giant tortoises, and on to the modern-day developments that now threaten its biodiversity.
    Palaeobiologist Thomas Halliday embraces a yet more epic timescale in Otherlands: A world in the making, touring the many living worlds that preceded ours, from the mammoth steppe in glaciated Alaska to the lush rainforests of Eocene Antarctica. If you have ever wondered what sound a pterosaur’s wings made in flight, this is the book for you.
    Given that nearly all of the species that have lived on Earth are extinct, it might be an idea to think about what we want to preserve from our current biosphere. In Tickets for the Ark: From wasps to whales – how do we choose what to save?, ecologist Rebecca Nesbit wonders how we might decide the fate of Earth’s estimated 8.7 million species, including ourselves. Are native species more valuable than newcomers? Should some animals be culled to protect others? And is it really our place to decide?
    Feathered friends
    As a species, we tend not to appreciate what we have lost until it is gone – or nearly gone. There are currently around 3 billion fewer birds in our skies than there were in 1970. And, perhaps not coincidentally, 2022 is a bumper year for books about birds.
    Faced with a quite catastrophic decline in bird populations, some writers have focused on what birds mean to our lives. In Birds and Us: A 12,000 year history, from cave art to conservation, ornithologist Tim Birkhead laces his own remarkable travels with the story of humanity’s long fascination with birds. We have worshipped them as gods, worn their feathers and even attempted to emulate their method of flight.
    Even without these cultural efforts, it seems that we share many of our behavioural traits with birds: our longevity, intelligence, monogamous partnerships, child-rearing habits, learning and language all have an avian equivalent, says behavioural ecologist Antone Martinho-Truswell. In The Parrot in the Mirror: How evolving to be like birds made us human, he shows how, from wildly different beginnings, the evolutionary stories of humans and birds have pushed both towards many of the same solutions. Sometimes we could do worse than to think of humans as featherless birds, he argues.
    “Birds not only have a keen sense of smell, they tweak the scents of the oils they use when preening”
    Might this kind of thinking inspire us to better orchestrate our rescue and preservation efforts? Patrick Galbraith’s In Search of One Last Song: Our disappearing birds and the people trying to save them crosses Britain on a journey that may well be his last chance to see some of our vanishing birds. On the way, he meets the people – reed cutters and coppicers, gamekeepers and conservationists – whose efforts sustain vital habitats for some of our rarest birds, but who often fall into misunderstanding and conflict with each other.
    While some focus on saving birds, other books offer a chance to understand them better. Douglas J. Futuyma’s How Birds Evolve: What science reveals about their origin, lives, and diversity traces avian species through deep time to explain how they developed such a rich variety of parenting styles, mating displays and cooperative behaviours.
    Evolutionary biologist Danielle J. Whittaker’s The Secret Perfume of Birds: Uncovering the science of avian scent adds a new feather to their cap with the news that birds not only have a keen sense of smell, but they tweak the scents of the oils they use when preening to attract mates and deter competitors. From tangerine-scented auklets to mossy-smelling juncos, birds are more fragrant than you might think.
    Joys of the cosmos
    Setting the wonders of Earth to one side, let’s examine the mysteries of space. In Black Holes: The key to understanding everything, physicists Brian Cox and Jeff Foreshaw use black holes, the most enigmatic objects in the universe, to explain some very profound physics. What is information? How could gravity and quantum theory one day be unified? And what actually is empty space?
    If that isn’t mind-bending enough, try physicist Nicole Yunger Halpern’s book Quantum Steampunk: The physics of yesterday’s tomorrow. In it, she reimagines 19th-century thermodynamics through a modern, quantum lens, playing with the aesthetics of the 1800s through trains, dirigibles and horseless carriages. It is a physics book, but one that is as likely to attract readers of science fiction as those of popular science.
    If you prefer a more straightforward approach, however, pick up physicist, writer and presenter Jim Al-Khalili’s The Joy of Science. It is a brief guide to leading a more rational existence. A little book of calm that is very welcome in these strange times.
    Fresh thinking
    Perhaps in response to these strange times, this year features several books that look at old notions in an entirely new way. In Am I Normal?: The 200-year search for normal people (and why they don’t exist), historian Sarah Chaney tells the surprisingly recent history of normal people.
    Before the 1830s, says Chaney, the term was hardly ever used to describe human behaviour. But with the advent of IQ tests, sex studies, censuses and data visualisations, we became ever more conscious of, and anxious about, human diversity. Can we ever learn to live with ourselves?
    Learning from the natural world might help in this regard. Lucy Cooke’s Bitch: A revolutionary guide to sex, evolution and the female animal clears away our outdated expectations of female bodies, brains, biology and behaviour and challenges our ideas about sexual identity and sexuality in humans and other animals.
    One aspect of life that seems difficult to argue with is the ageing process. But in Jellyfish Age Backwards: Nature’s secrets to longevity, Nicklas Brendborg asks not just why we grow old and die, but what we can do about it. What can we learn from the Greenland shark that was 286 years old when the Titanic sank and is still going strong; from the many living things that have never evolved to die, and succumb only through unfortunate circumstances; or from one species of jellyfish that can revert back to its polyp stage when threatened and, remarkably, “age again”?
    A related question is how bodies, communities and systems regenerate. This is a pressing issue in regenerative medicine, in developmental biology and in neuroscience. In What Is Regeneration?, philosophers of science Jane Maienschein and Kate MacCord point out that this rapidly growing field of study also promises to transform our ability to understand and repair the damage to ecosystems brought on by climate change.
    In an acid test of our willingness to see clearly and embrace reason, there is Endless Forms: The secret world of wasps, behavioural ecologist Seirian Sumner’s bid to make us love an animal that is older, cleverer and more diverse than its cuddly cousin the bee. Learning that nearly every ecological niche on land is inhabited by a wasp, and that there are wasps that live inside other wasps, may make you fall in love with the things. But then again…
    Observation points
    Another component of great science is, of course, observation – a skill we should all nurture if we want to appreciate our brief time on the planet.
    Rolf Sachsse, a curator based in Bonn, Germany, has gathered together the very best of the remarkable work of English botanist and photographer Anna Atkins (1799-1871) in Anna Atkins: Blue prints. It is a sumptuous celebration of the sort of close observation that contributes so much to both science and art. Atkins used the then recently invented “cyanotype” process to photograph algae and ferns, thereby creating the first photo book in history.
    Barriers to good observation are more often social than practical. History isn’t short of remarkable female astronomers, but before the 1960s, women invariably needed the right relative or the right husband to champion and support their work. The Sky Is for Everyone: Women astronomers in their own words is a testament to the period that all changed. Edited by astronomers Virginia Trimble and David Weintraub, it is an inspiring anthology of writings by trailblazing female astronomers from 1960 to today.
    And finally: close observation, fresh thinking and a concern for the environment all come together in Dust: A history and a future of environmental disaster by Jay Owens – for my money, the most enticing of the books we know are due in 2022.
    “What can we learn from the shark that was 286 years old when the Titanic sank and is still going strong?”
    Owens explores dust as a method for seeing the world anew, from space dust to sandstorms, from the domestic to the digital and from efforts at industrialisation to the latest speculative technologies for cooling the planet. Though dust may often be the harbinger of environmental disaster, Owens, like many of the writers here, still makes room to draw out stories of hope, of salvage and of repair.

    We must capitalise on the public's renewed focus on climate change

    By Adam Corner
    Simone Rotella
    LAST year saw a wave of climate change coverage and record levels of public concern. One poll found that 40 per cent of people in the UK thought climate change was the most important issue facing the country, and a major 30-country study found similar results, with most people in most countries now worried about climate change. They wanted both government and personal action to address the problem. These are uncharted waters for public opinion across the planet.
    This is a welcome development and it is long overdue. But it represents the start, rather than the finish line for public … More

    The best sci-fi TV shows and movies to look forward to in 2022

    By Swapna Krishna
    James Dimmock/CBS
    The best films and TV
    Towards the end of 2021, a glut of movies and shows that had been delayed by covid-19 finally hit the screens. Next year, that trend continues with a plethora of sci-fi offerings.
    Paramount Plus (which is due to launch in the UK in 2022) has a double treat for fans of the Star Trek franchise. Patrick Stewart stars in a new series of Star Trek: Picard, which returns in early 2022. Later in the year, the first season of Star Trek: Strange New Worlds will bring back fan favourites such as Spock, Uhura and Number One.
    Over in the Star Wars universe, Obi-Wan Kenobi starring Ewan McGregor and Hayden Christensen will premiere on Disney+. The streaming service will also bring back Diego Luna as Cassian Andor from Rogue One in Andor.Advertisement
    Back on Paramount Plus, a new show, Halo, based on the hit video game series, will also be released in early 2022. Set in the 26th century, it will focus on a war between humans and aliens, with Pablo Schreiber set to play the legendary Master Chief.
    From Westworld creators Jonathan Nolan and Lisa Joy, comes a new high-concept series for Amazon Prime Video called The Peripheral, based on a book by William Gibson. It focuses on a detective (played by Chloë Grace Moretz) who believes that she witnessed a murder in cyberspace.
    On the big screen, the threats are more tangible. February sees the release of Moonfall, in which Halle Berry stars as a NASA executive and former astronaut who must take action when the moon breaks its orbit and is set to collide with Earth.
    Space thriller 65 is set for release in April. Few details have been released, except that the main character, played by Adam Driver, arrives on another planet to discover he isn’t alone.
    On a lighter note, Disney Pixar’s Lightyear comes to cinemas in June. Set in the Toy Story universe, it traces the origins of Buzz Lightyear — the “real” astronaut that was immortalised as a children’s toy in the cartoons.
    It is also a big year for long-awaited sequels. Avatar 2 finally arrives at the end of the year, more than 10 years after James Cameron introduced us to the world of Pandora. And Jurassic World: Dominion will roar onto big screens in June for one last adventure starring Chris Pratt and Bryce Dallas Howard.
    Whatever else this year brings, we certainly won’t be short of entertainment.

    The mummy of Egyptian pharaoh Amenhotep I has been digitally unwrapped

    Amenhotep I ruled Egypt from around 1525 to 1504 BC and his pristine mummy has never been unwrapped, but CT scans have now allowed us to peer inside

    Humans

    28 December 2021

    By Alex Wilkins
    Face mask of the never-before unwrapped mummy of pharaoh Amenhotep IS. Saleem and Z. Hawass
    One of the last remaining unwrapped royal Egyptian mummies has been scanned in detail for the first time.
    Amenhotep I, who ruled Egypt from around 1525 to 1504 BC in an era known as the New Kingdom, was found in 1881 by a French Egyptologist. But the king’s mummy was left untouched due to a highly preserved wrapping and ornate face mask. It has remained sealed in its sarcophagus ever since.
    Now, Sahar Saleem and Zahi Hawass at the University of Cairo in Egypt have “digitally unwrapped” Amenhotep I’s mummy with computed tomography (CT), using hundreds of high resolution X-ray slices to map out the ancient king’s skeleton and soft tissue.Advertisement
    “Royal mummies of the New Kingdom were the most well-preserved ancient bodies ever found, so these mummies are considered a time capsule,” says Saleem.
    “They can tell us about what the ancient kings and queens looked like, their health, ancient diseases, mummification techniques and manufacturing methods of funerary objects.”
    Amenhotep I’s mummy has been examined using simple X-ray scans in the past, but the detailed CT scan reveals several new facts: his bone structure indicates that he was 35 years old and 168.5 centimetres tall when he died.

    The study also seems to answer a long-standing mystery: previous scans had revealed that Amenhotep I had been embalmed by Egyptian priests for a second time 300 years after he was first entombed, after graverobbers apparently plundered his coffin. Saleem had theorised that the priests used this occasion to pilfer precious jewels placed on the body and in the bandages for themselves before re-embalming him.
    But the plentiful jewellery revealed in the scan  reveals that the priests “lovingly” re-embalmed Amenhotep I, according to Saleem. It was because the priests’ handiwork was so impressive and the mummy’s appearance was so pristine more than 3000 years later that 19th century archaeologists were convinced to leave him permanently unwrapped.
