    IF ALL the human cells in your body were to suddenly dematerialise, your outline would briefly persist, in all its exquisite detail, in the form of the billions of bacteria and viruses that colonise your every nook and cranny, still suspended in the shape of the frame your body provided.
    Something analogous happens in Lauren Beukes’s novel Afterland, available in July worldwide and in September in the UK. Over about two years, a pandemic kills nearly every man in the world, leaving its patriarchal systems staffed exclusively by women. Cole, the mother of one of the precious few surviving boys, needs to get him out of the US and back to their home in South Africa. Her sister, meanwhile, wants to sell him. This gives the novel its structure and speed: it is a deceptively simple heist caper, with Cole on the run across the US from both her sister and the Department for the Protection of Males.
    The organisation is charged with imprisoning the few males that remain, probing them to find whatever biological quirk has spared them from the plague and using that knowledge to find a vaccine for the virus. Its aim of jump-starting society “back to normal” will be uncomfortably familiar as we too languish in a pandemic limbo between the Before and the After, hoping for our own vaccine. The misguided waiting game in the novel results in a few temporary accommodations to reality: straight women negotiate awkward first dates with one another, while fake baby bumps become the hottest fashion accessory.
    So who gets to maintain civilisation now, and do women run a better society than men? This is where the book shines as one of the best thought experiments of its kind, in which Beukes has stitched together the surprise matriarchy of The Power, the millenarian despair of Children of Men and the deeply intelligent questions of Ursula Le Guin’s The Left Hand of Darkness.
    The Power – in which women develop the ability to give electric shocks, ending their status as the “weaker sex” once and for all – concludes that women are just as bad as men when in ultimate control.

    Beukes’s take is more ambiguous. Like Le Guin, she seems to conclude that it doesn’t much matter if it is women or men in charge of society, as it is the structures themselves that turn us into monsters. “You have to be bigger and meaner as a woman to claim your turf,” Cole’s sister tells herself, negotiating her nephew’s kidnapping on behalf of the widow of the kingpin she used to work for. The widow has slid into his place, just as easily as the thugs around her have shifted from being vicious beauty queens to vicious enforcers. The Sisters of Sorrow, the religious community in which Cole and her son take refuge, somehow figures out how to make Christianity even more violently misogynistic in a world without men.
    “There is no guarantee that the once-oppressed will wield power any more judiciously than their oppressors”
    Yet it isn’t all nihilism. Beukes seeds the book with hopeful rumours of matriarchal societies that have sprung up in other countries. There are never many details beyond the promise, like mirages just over the horizon. “They say the matriarchal societies have been a lot better about getting rid of the homosexuality laws,” promises an email from a friend trying to help them escape across the Atlantic. It is a promise of a better body politic.
    Afterland is that rare creature, a ripping tale that neither shies away from big questions nor interesting answers. What happens when the powerless get power? There is no guarantee that the previously oppressed will wield it any more judiciously than those who oppressed them. It isn’t about the individuals. It is about the society they need to maintain.

    Humans reached the Americas 15,000 years earlier than thought

    By Michael Marshall
    Tools found in the Chiquihuite cave in Zacatecas, Mexico, suggest humans arrived there early
    Mads Thomsen

    HUMANS seem to have been living in the Americas as early as 33,000 years ago – 15,000 years before the most widely accepted date. The finding implies that people arrived there before the peak of the last glacial period and there is a long American prehistory we are yet to uncover.
    The first American settlers were probably Homo sapiens, but we can’t rule out extinct groups like Neanderthals and Denisovans. The settlers probably entered from north-east Asia across a land bridge linking Asia and Alaska. This was submerged by rising seas when the ice sheets melted at the end of the last glacial period.
    Most archaeologists accept that humans were in the Americas 18,000 years ago. Now two studies bolster the idea that people got there much earlier.

    Ciprian Ardelean at the Autonomous University of Zacatecas in Mexico and his colleagues have spent the past decade excavating Chiquihuite cave in Zacatecas. They have found almost 2000 stone tools buried in sediments in the cave, including blades, points and scrapers. No human remains or DNA have been found.
    The youngest samples of sediment are at least 12,200 years old, and the oldest may be 33,150 years old (Nature, DOI: 10.1038/s41586-020-2509-0). This suggests that people lived in the Americas before a crucial event: the last glacial maximum – the peak of the last glaciation. Between 26,500 and 19,000 years ago, ice sheets extended across much of North America. This was thought to make condition too harsh for people to enter the Americas, but the new findings suggest humans were already present.

    The second study compiles reliably dated archaeological sites to track the spread of people across North America. Lorena Becerra-Valdivia at the University of New South Wales in Australia and Thomas Higham at the University of Oxford, who are also on Ardelean’s team, assembled dates from 42 sites in North America and north-east Asia. Chiquihuite cave was the oldest reliably dated site (Nature, DOI: 10.1038/s41586-020-2491-6).
    During and just after the last glacial maximum, North America seems to have been sparsely populated, with numbers exploding about 14,700 years ago as the ice receded, says Becerra-Valdivia.

    The two studies offer “strong evidence for an earlier presence of humans in North America than has been fully accepted”, says Deborah Bolnick at the University of Connecticut.
    Until now, it has been widely assumed that only modern humans reached the Americas, since groups like Neanderthals died out millennia before anyone was thought to have got there. Ardelean says we shouldn’t assume that any more. “I don’t see why other species wouldn’t have entered America,” he says.
    But Bolnick and Becerra-Valdivia both say the first Americans were most likely to have been modern humans.

    This is the first picture of a sunlike star with multiple exoplanets

    For the first time, an exoplanet family around a sunlike star has had its portrait taken. Astronomers used the Very Large Telescope in Chile to snap a photo of two giant planets orbiting a young star with about the same mass as the sun, researchers report July 22 in The Astrophysical Journal Letters.
    The star, called TYC 8998-760-1, is about 300 light-years away in the constellation Musca. At just 17 million years old, the planetary family is a youngster compared with the 4-billion-year-old solar system.
    Although astronomers have found thousands of exoplanets, most aren’t observed directly. Instead they are spotted as shadows crossing in front of their stars, or inferred as unseen forces tugging at their stars.
    Only a few tens of planets have been photographed around other stars, and just two of those stars have more than one planet. Neither is sunlike, says astronomer Alexander Bohn of Leiden University in the Netherlands — one is more massive than the sun, the other less massive.
    Both of this star’s planets are unlike anything seen in the solar system. The inner planet, a giant weighing 14 times the mass of Jupiter, is 160 times farther from its star than Earth is from the sun. The outer one weighs six times Jupiter’s mass and orbits at twice its sibling’s distance. In comparison, the Voyager 1 spacecraft, which flew past the boundary marking the sun’s magnetic influence and into interstellar space in 2012, is still closer to the sun than either planet is to its star (SN: 9/12/13).
    This exoplanet family could provide new insight into how solar systems can form. “As with many other exoplanet discoveries, this discovery makes us aware of other scenarios that we did not think of,” Bohn says. More

    Pinning down the sun’s birthplace just got more complicated

    The sun could come from a large, loose-knit clan or a small family that’s always fighting.
    New computer simulations of young stars suggest two pathways to forming the solar system. The sun could have formed in a calm, large association of 10,000 stars or more, like NGC 2244 in the present-day Rosette Nebula, an idea that’s consistent with previous research. Or the sun could be from a violent, compact cluster with about 1,000 stars, like the Pleiades, researchers report July 2 in the Astrophysical Journal.Whether a star forms in a tight, rowdy cluster or a loose association can influence its future prospects. If a star is born surrounded by lots of massive siblings that explode as supernovas before a cluster spreads out, for example, that star will have more heavy elements to build planets with (SN: 8/9/19).
    To nail down a stellar birthplace, astronomers have considered the solar system’s chemistry, its shape and many other factors. Most astronomers who study the sun’s birthplace think the gentle, large association scenario is most likely, says astrophysicist Fred Adams of the University of Michigan in Ann Arbor, who was not involved in the new work.
    But most previous studies didn’t include stars’ motions over time. So astrophysicists Susanne Pfalzner and Kirsten Vincke, both of the Max Planck Institute for Radio Astronomy in Bonn, Germany, ran thousands of computer simulations to see how often different kinds of young stellar families produce solar systems like ours.

    The main solar system feature that the pair looked for was the distance to the farthest planet from the star. Planet-forming disks can extend to hundreds of astronomical units, or AU, the distance between the Earth and the sun (SN: 7/16/19). Theoretically, planets should be able to form all the way to the edge. But the sun’s planetary material is mostly packed within the orbit of Neptune.
    “You have a steep drop at 30 AU, where Neptune is,” Pfalzner says. “And this is not what you expect from a disk.”
    In 2018, Pfalzner and her colleagues showed that a passing star could have truncated and warped the solar system’s outer edge long ago. If that’s what happened, it could help point to the sun’s birth environment, Pfalzner reasoned. The key was to simulate groupings dense enough that stellar flybys happen regularly, but not so dense that the encounters happen too often and destroy disks before planets can grow up.
    “We were hoping we’d get one answer,” Pfalzner says. “It turned out there are two possibilities.” And they are wildly different from each other.
    Large associations have more stars, but the stars are more spread out and generally leave each other alone. Those associations can stay together for up to 100 million years. Compact clusters, on the other hand, see more violent encounters between young stars and don’t last as long. The stars shove each other away within a few million years.
    “This paper opens up another channel for what the sun’s birth environment looked like,” Adams says, referring to the violent cluster notion.
    The new study doesn’t cover every aspect of how a tight cluster could have affected the nascent solar system. The findings don’t account for how radiation from other stars in the cluster could erode planet-forming disks, for example, which could have shrunk the sun’s disk or even prevented the solar system from forming. The study also doesn’t explain certain heavy elements found in meteorites, which are thought to come from a nearby supernova and so could require the sun come from a long-lived stellar family.
    “I think [the research] is an interesting addition to the debate,” Adams says. “It remains to be seen how the pieces of the puzzle fit together.”
    Pfalzner thinks that the star cluster would break apart before radiation made a big difference, and there are other explanations for the heavy elements apart from a single supernova. She hopes future studies will be able to use that sort of cosmic chemistry to narrow the sun’s birthplace down even further.
    “For us humans, this is an important question,” Pfalzner says. “It’s part of our history.” More

    The closest images of the sun ever taken reveal ‘campfire’ flares

    Get out the marshmallows and toasting sticks. The closest images yet taken of the sun show tiny flares dubbed “campfires,” astronomers announced in a news conference on July 16.
    The images are the first from Solar Orbiter, a new sun-watching spacecraft that’s a joint project between NASA and the European Space Agency.
    “By looking from close by, we get so much sharper images,” said David Berghmans of the Royal Observatory of Belgium in Brussels in the news conference. The pictures were better than the science team expected. “When the first images came in, the first thought was, ‘This is not possible! It cannot be that good.’”   
    These never-before-seen campfire flares are thought to be little relatives of larger solar flares, powerful magnetic outbursts that shoot bright spurts of radiation into space (SN: 9/11/17). Campfire flares are a million to a billion times as small as typical solar flares. The smallest ones in the Solar Orbiter images are a few hundred kilometers across, “about the size of a European country,” Berghmans said. It’s not clear yet whether the flickers are just scaled-down solar flares, or if the two phenomena have different driving mechanisms.

    Solar physicists think campfires could help explain one of the biggest solar mysteries: why the solar corona, the sun’s wispy outer atmosphere, is millions of degrees hotter than the solar surface (SN: 8/20/17). Together, the small but ubiquitous flares could be a source of energy to the corona that astronomers haven’t accounted for.
    “These campfires are totally insignificant each by themselves, but summing up their effect all over the sun, they might be the dominant contribution to the heating of the solar corona,” said Frédéric Auchère of the Institut d’Astrophysique Spatiale in Orsay, France, in a news release.
    Solar Orbiter captured these pictures of “campfire” flares (indicated with arrows) on the sun in extreme ultraviolet wavelengths of light. The newly spotted flares may help heat the sun’s outer atmosphere.Solar Orbiter/EUI Team/ESA and NASA, CSL, IAS, MPS, PMOD/WRC, ROB, UCL/MSSL
    Solar Orbiter launched February 9 with a suite of scientific instruments to observe the sun and its surroundings (SN: 2/9/20). The new images were taken May 30 with the Extreme Ultraviolet Imager camera when the spacecraft was 77 million kilometers from the sun, about half the distance from Earth. Berghmans and Auchère are the principal investigators for the orbiter’s ultraviolet camera.
    Other spacecraft have swooped closer to the sun. The Parker Solar Probe has gotten as close as 24 million kilometers, collecting data but no direct photos because it gets too close (SN: 12/4/19). It will eventually reach 6 million kilometers from the sun’s surface. Ultimately, Solar Orbiter will come within about 42 million kilometers of the sun, and will be the first spacecraft to fly over the sun’s poles. More

    Alice Ball pioneered leprosy treatment and then had her work stolen

    Short film The Ball Method tells the story of Alice Ball. She helped develop an effective treatment for leprosy, then a senior colleague claimed her work as his own giving her no credit

    IN it declared global elimination on that basis in 2000 I think: 2000, the World Health Organization declared that leprosy had been eliminated as a global public health problem, due to effective multi-drug treatments. It is a disease that has long been stigmatised due to disfiguration it can cause. The story of one unsung hero in the development of a treatment for leprosy is told in the short film The Ball Method.
    The story starts with archive footage of the Hawaiian island of Moloka’i, where thousands of people with leprosy were quarantined from 1866 by the Hawaiian government. Back then, little was known about the disease and people feared it was highly contagious, though we now know it doesn’t spread very easily.
    Countries such as the UK, the US and India exiled people with leprosy to remote locations, where they were left to die. One of the film’s clips shows a child covered in sores on his face and hands.
    By 1915, when the film is set, one remedy was beginning to show promise. We are introduced to Alice Ball (played by Kiersey Clemons), a chemistry professor at the University of Hawaii, as she visits Kalihi Hospital in Honolulu. Ball has been enlisted to help develop a treatment for leprosy by Dr Harry Hollmann (Kyle Secor) using the oil from the seeds of the chaulmoogra tree. Chaulmoogra oil seemed to work in treating some cases of leprosy and had already been used for centuries in China and India for skin ailments.

    Taking the oil orally caused nausea, so it was administered by injection. But this method was flawed. In its unpurified form, chaulmoogra oil isn’t water soluble and doesn’t react well with the body; oil oozes painfully out of the forearm of one patient with leprosy as he is given a shot.
    “Ball was the first woman and first black American at the University of Hawaii to teach chemistry”
    In between teaching students at her university, Ball tries to purify the oil into chemical compounds called ethyl esters so it can be successfully injected. To do this, the oil first needs to be converted into fatty acids. Ball has a eureka moment. She realises the acid needs to be frozen overnight to give enough time for the esters to separate, as well as to stop them degrading at room temperature.
    Her discovery, the Ball method, led to the most effective treatment for leprosy at the time, one that was used until the 1940s, when a full cure was found. Why, then, is Alice Ball not more famous?
    One reason is that credit wasn’t given to her at the time. Ball’s colleague Arthur Dean (played by Wallace Langham), who was president of the University of Hawaii, took her findings as his own, naming the technique the Dean method. There was no mention of Ball in his papers. She didn’t get credit until 1922 when Hollmann published a paper detailing her work.
    Director Dagmawi Abebe says this is why he felt it was so important to make the film. “When I came across Alice’s story and saw all the amazing accomplishments she’s done, and how not a lot of people even knew about her, I really wanted to make that known.”
    There are few historical records about Ball. She didn’t keep a diary that we know of and died in 1916 aged 24, possibly after inhaling chlorine gas in a lab accident.
    So Abebe had to make a lot of choices in how to portray her. He says he wanted to depict her as strong and ambitious given the barriers she is likely to have faced.
    Looking at the facts, that doesn’t seem like much of a stretch. At only 23, Ball was the first woman and first black American to teach chemistry and obtain a master’s degree at the University of Hawaii. But being a black woman in this environment wasn’t easy. In one scene, as Ball takes a class, students (all male and white) snigger as they pass around a picture of a crudely-drawn monkey.
    For Abebe, who is originally from Ethiopia, it was important to highlight this aspect of Ball’s experience. “I’m interested in telling a story where I feel like a lot of minority stories went untold or hidden,” he says. This narrative is at last finding a wider audience.
