A shrine built more than 3000 years ago in what is now Turkey may be a symbolic representation of the cosmos, according to a new interpretation.
It has now been suggested that the elite of the Hittite society, an empire that dominated what is now Turkey between 1700 and 1100 BC until it was destroyed, created the Yazılıkaya shrine to embody their ideas about how the universe was organised.
Yazılıkaya contains many images in rock relief, and the researchers behind the new interpretation argue that these have symbolic meanings relating to the underworld, earth and sky, as well as to cycles of nature like the seasons.Advertisement
“There are many connotations with the names of the deities and the arrangements and groups, and so in retrospect it’s pretty easy to figure it out,” says Eberhard Zangger, president of Luwian Studies, an international non-profit foundation. “But we worked on it for seven years.”
“They may be onto something,” says Ian Rutherford at the University of Reading in the UK. “I’m not convinced of all the details, but very interested in the whole thing.”

Yazılıkaya is an open-air shrine and was one of the most important sites of the Hittite Empire. The remains of the Hittite capital Ḫattuša can be found near the modern village of Boğazkale in central Turkey. Yazılıkaya is within walking distance of the ancient capital.
At Yazılıkaya, the Hittites carved and modified natural rock outcrops to create two roofless spaces, decorated with rock relief images of their deities. They used the site for centuries; its present form dates from about 1230 BC.
It isn’t clear why the Hittites built Yazılıkaya or what they used it for. Many ideas have been proposed – for instance, that one of the spaces was used in new year ceremonies, and that the other was a mausoleum for a Hittite king.
In 2019, Zangger and his colleague Rita Gautschy at the University of Basel in Switzerland suggested that some of the carvings of gods might be a calendar, able to track both solar years and lunar months. Such a calendar would have been centuries ahead of its time, and the interpretation was greeted with scepticism.
Now, the pair and their colleagues have taken a new tack. Instead of focusing on the possible uses of the carvings, the researchers have considered what these might have meant to the Hittites.

“They had a certain image of how creation happened,” says Zangger. He says the Hittites imagined that the world began in chaos, which became organised into three levels: “the underworld, and then the earth on which we walk, and then the sky”.
As part of this, Zangger says the Hittites would have highlighted the circumpolar stars, which never sink below the horizon. He argues that one prominent group of deities in Yazılıkaya represents the circumpolar stars. “There are images like that in Egypt,” he says, and the Hittites were influenced by many neighbouring societies, including Egypt. Other carvings may have links to the earth and the underworld.
The second aspect of Hittite cosmology was “recurrent renewal of life”, says Zangger – for instance, day following night, the dark moon turning into a full moon and winter becoming summer. The calendar-like carvings reflect this cyclical view of nature, he argues.

“As an idea, it’s not far-fetched,” says Efrosyni Boutsikas at the University of Kent in Canterbury, UK. Other cultures, ranging from nearby Mesopotamia to distant Mesoamerica, used religious monuments to link terrestrial life with the wider universe. “Obviously that makes sense, because that’s exactly what religion does. It addresses universal concerns and the place of the people in the world,” she says.
However, Boutsikas is concerned that many of the team’s interpretations of the images aren’t based on Hittite texts, which say little about astronomy. Instead, the researchers have often used texts from Mesopotamian societies, which influenced the Hittites but were also distinct. She says the evidence would be stronger if similar links between gods and astronomy could be found at other Hittite sites.

The Ants and the Grasshopper
Raj Patel and Zak Piper
Kartemquin FilmsAdvertisement
ANITA CHITAYA is an extremely determined person. A leader in the Malawian village of Bwabwa, she converts men to gender equality, fights to end child hunger and was ready to take on an impossible mission: travelling to the US to persuade then president Donald Trump that climate change is real and a threat to both rich and poor.
Chitaya is at the heart of The Ants and the Grasshopper by directors Raj Patel and Zak Piper, shown at the 2021 Sheffield Docfest this month. The film emerged from work by Patel, a professor in food systems at the University of Texas at Austin. It starts with Chitaya’s life in Bwabwa, moves to her journey across the US in hope of accessing the White House, and ends with a short epilogue after her return.
The opening section makes the origins of Chitaya’s gender work clear. After a tough childhood, she was forced into an “abduction marriage” by her husband-to-be Christopher, his friend Winston and a group of other men. She didn’t feel she could fight because of a strong local belief that refusal to marry might have killed her mother.
Some time later, she met Esther Lupafya, an activist and nurse who co-founded a non-profit organisation called Soils, Food and Healthy Communities (SFHC), and her life changed. SFHC now works with more than 6000 farmers in northern and central Malawi, who exchange knowledge to improve soil fertility, food security and nutrition, and in the process encourage gender equity and resilience against climate change.
Christopher seems to genuinely regret his past deeds and does his best to support Chitaya, but Winston stubbornly refuses to help his wife Jenifa cook, farm, water plants or do other chores seen as women’s work. At SFHC, Chitaya learns more about climate change, convincing her neighbours to build clay stoves and reduce their firewood use. Unsurprisingly, she accepts the directors’ invitation to fly to the US with Lupafya.
“Many in the US don’t fully understand what it means that we in Malawi live on the same planet as them”
During one early visit, to the village of Wonewoc, Wisconsin, Chitaya and Lupafya explain how climate change helped make their soil arid. One young farmworker argues that the world is undergoing a “weather cycle”, refusing to accept the phenomenon’s scale.
As it unfolds, the film shows encounters with farmers and activists both urban and rural, who in turn reflect awareness, advocacy, indifference or mild scepticism, as Patel and Piper struggle to make the links between gender inequality, poverty, racism and environmental issues explicit.
Anita Chitaya wants people to understand the impact of climate changekartemquin films
It is ambitious for a 74-minute film, and the directors take unwarranted shortcuts. We see only individuals on whom their encounter with Chitaya had a positive effect in the long term. In the epilogue, the farmworker from Wisconsin regrets laughing at Chitaya’s concerns. He now runs an organic chicken farm, proving he has changed. We also learn that 18 months after her visit, Democrat senator Jeff Merkley co-sponsored the Green New Deal, although the impact of Chitaya’s efforts is unclear. Merkley’s office is as close as she gets to the White House.
The Ants and the Grasshopper attempts a fresh take on complex issues, but remains on the surface because it draws on too much material. It is the powerful portrait of Chitaya’s courage, however, that makes the film worth watching. In one of the last scenes, Winston pounds maize and joins a cooking demonstration, proving he has finally learned the value of caring.
But shortly after an image of a dead grasshopper borne away by ants, Chitaya says that many in the US don’t fully understand what it means that “we live on the same planet as them”; there are many ants, but only a few lifting the grasshopper. A deeper focus on her fight against climate change and local inequality could have delivered a stronger message, but may not have been as messily truthful.

Georgia King plays failing artist Leena in ParallelShane Harvey
Parallel
Isaac Ezban
DVD and VODAdvertisement

WHAT if you could step through a mirror and visit other versions of the world? Would you explore these alternate Earths? Would you try to find a better home for yourself – in a world, perhaps, where a loved one hasn’t died?
Or, as happens in Parallel, Mexican director Isaac Ezban’s first English-language thriller, would you simply go around stealing?
Of the four young friends who discover a dimensional portal in the attic of their rental, only Devin (Aml Ameen) thinks it might be a means of personal salvation. As a boy, he flew into a rage at his fraudster father, who killed himself the next day. Now Devin is in search of a version of the world where his father lives, and the rift can be healed.
His friends, however, simply want to get rich. The four have been working together on a parking app called Meter Maid: an idea so uninteresting, I wonder if it is meant as an early comment on their lack of real talent.
Behind their mirror, through which they pass, Alice-fashion, into other versions of the world, time runs faster. For a moment, it seems that to get stupidly rich, all they have to do is bring back the winning lottery numbers from alternate realities. But the worlds they visit, though very similar, are different enough that the winning numbers don’t match up.
Is there a way to exploit these little differences? Screenwriter Scott Blaszak’s first feature fizzes with incidental invention as the friends explore the commercial and financial angles of their multiverse. Their solutions are tailored to character. In the end, Josh (Mark O’Brien), the group lightweight, goes chasing women across the multiverse. Meanwhile, failing artist Leena (Georgia King) fills portfolios with plagiarised pictures and Noel (Martin Wallström, effectively reprising his role in Mr Robot) steals the intellectual property of unwitting inventors. No spoilers about the end result of all this, but it is a catastrophe worth waiting for.
“Handed a world of infinite possibility, all the film’s characters can do is play out their failings”
Parallel is no masterpiece. Made on a shoestring, and boasting a silly and intrusive soundtrack, its fairly familiar premise depends on the sharpness of its ideas. Luckily, Blaszak knows what he is doing, and has given us characters who, while engaging enough, aren’t good people. Handed a world of infinite possibility, all they can do is play out their failings.
They aren’t even very curious. Bankrolled with money stolen from their “alt” selves, they consume, but they cannot create. Their cruelty is as devastating as it is casual. By bringing an alt Josh into our world, Noel destroys at least one innocent life. Then the alt Josh begins to mentally disintegrate, tormented by the tiny but ubiquitous differences between his world and ours.
Ezban’s direction is efficient, more than inspired. Those wondering what he could achieve on a bigger budget might not have too long to wait. He has been hired by Sony Pictures to direct the adaptation of Dan Simmons’s horror novel Summer of Night.
Meanwhile, Parallel is a well-constructed calling card. It is a film with heroes that are meant to be likeable, flawed as they are. Pulling its punches in this way gives the enterprise a curiously dated feel. I was reminded in particular of Joel Schumacher’s Flatliners and The Lost Boys. Not every movie has to plummet the depths of despair, of course. But I do wish Parallel‘s cast (Wallström in particular) had been handed more of an opportunity to chew up the set.

AS MOST of the UK recovers from a frigid April and a soggy May, its gardens are starting to perk up. That means so are caterpillars, aphids such as greenflies, and other plant-feeding invertebrates generally seen as the gardener’s foes.
A common reaction to seeing prized plants covered with bugs is to reach for the pesticide spray. But we should temper that instinct, says Andrew Salisbury, principal entomologist at the UK Royal Horticultural Society. Many invertebrate species in the UK and elsewhere are in decline, and gardens can be a haven – the UK’s home gardens collectively add up … More

Behavioural scientists Daniel Kahneman and Olivier Sibony explain why “noise” in professional judgements harms everything from criminal justice to medical treatments

Humans

If you have ever jumped to the wrong conclusion, made a terrible mistake thanks to your inbuilt biases or been subtly nudged back to your senses, then you are (a) human and (b) already on personal terms with the work of Daniel Kahneman, Olivier Sibony and Cass Sunstein. Thanks to their academic and popular writing, the world is now very familiar with what are collectively called “cognitive biases” – systematic errors in human thinking – and ways to correct them.
Sunstein co-wrote the highly influential book Nudge: Improving decisions about health, wealth and happiness with Richard Thaler, while Kahneman popularised the work that won him the Nobel prize in economics in 2002 with his book Thinking, Fast and Slow. Sibony is the author of You’re About to Make a Terrible Mistake: How biases distort decision-making and what you can do to fight them.
You may think that, in no small part thanks to their efforts, the swamp of human fallibility has been well and truly drained by now. But that would be yet another mistake. Kahneman, Sibony and Sunstein say there is an even more important source of warped decision-making. The three have banded together in a behavioural science supergroup to draw attention to what they call “noise” – persistent inconsistencies in professional judgements that lead to bad outcomes in all walks of life.
Kahneman and Sibony spoke to New Scientist about the group’s new book Noise: A flaw in human judgment (Little, Brown Spark in the UK; William Collins in the US). Sunstein was due to join the conversation, but was called away at the last minute by his … More

(L-R) Lucius Hoyos as Noah, Gina Rodriguez as Jill, Ariana Greenblatt as MatildaPeter H. Stranks/NETFLIX
In the dystopian sci-fi movie Awake, everyone on Earth suddenly loses the ability to sleep, plunging the world into hysteria.
As scientists race to find a cure, ex-soldier Jill Adams (Gina Rodriguez) discovers that her young daughter Matilda (Ariana Greenblatt) might just possess the means to save mankind.
 Awake’s compelling premise is enough to make the opening of the film enjoyable. Director Mark Raso slowly cranks up the tension – there are some unsettling set pieces, and the film doesn’t waste time trying to explain the phenomenon. Instead, the slow reveal of information does enough to keep you hooked.Advertisement
Unfortunately, though, Awake soon goes off the rails. Raso is constantly trying to create the same mindset of those who are unable to sleep in the viewers, but it just makes things increasingly confusing.
It also doesn’t help that, by only following Jill’s relationship with Matilda and her son Noah (Lucius Hoyos), Awake is too contained. We learn very little about what’s going on across the world, so when symptoms suddenly escalate and humanity descends into anarchy, it has very little impact.
But what would actually happen if you suddenly couldn’t sleep?

Alastair McLean at Queen’s University in Kingston, Ontario, who specialises in sleep deprivation, says its biggest impact is on interpersonal interactions, as people quickly become quite irritable.
“In terms of performance, one of the most obvious things that happens are microsleeps,” says McLean, in which people fall asleep for up to 30 seconds and can’t remember what happened. “They can occur after 24 hours.”

There is also cognitive slowing, which sees people taking longer to make decisions, and cognitive rigidity, in which individuals can only think about things in one fixed way. Loss of motivation, paranoia, memory and balance issues, mood changes and visual problems can also occur, while some people experience hallucinations and even speech difficulties.
In 1963, 17-year-old Randy Gardner set the record for the longest time a human had gone without sleep, staying awake for 11 days and 25 minutes. Finland’s Toimi Soini and the UK’s Maureen Weston and Tony Wright have allegedly beaten this time, but none of them were studied as closely as Gardner.
Studies of sleep deprivation on animals have also proven to be revealing. “In 1989, Allan Rechtschaffen and his Chicago group studied rats that were sleep deprived. After two to three weeks, they started to die,” says McLean. “You saw the same pattern in all of them. They began to eat more and more as the sleep loss went on. Despite that, they had a fall in body weight.”

A 2020 study by researchers at Harvard Medical School on sleep deprivation in fruit flies also provided the same outcome. The more they didn’t sleep, the greater the increase in a molecule in the gut known as reactive oxidative species.
“If they gave the fruit flies materials to offset the effects of this, they didn’t die,” says McLean. “We’ve been looking for the effects of sleep deprivation in the brain. It looks, though, that it’s the gut that may be critical when it comes to survival.”
Based on the trailer for Awake, McLean agrees that it looks accurate in its use of disorientation and even hallucinations, but says it appears to exaggerate the problems and even speed up the timeframe in which they occur.
By doing just, that Awake strains to repeat the success of thrillers like A Quiet Place and Bird Box. But not only does it lack the ingenuity, tension and star power of these films, it is too aimless, meandering and lacking in heart to come close.
Awake is now available on Netflix .

A Quantum Life: My unlikely journey from the street to the stars

THEY called him “the professor” because, by the age of 10, he was already reading every book he could lay his hands on. In the sixth grade, he scored 162 on an IQ test at school. Still, by the time he was in his teens, the certified genius was dealing weed and carrying a gun for protection.
“If anyone had told me I’d grow up to be an actual professor at MIT, UC Berkeley, and the University of Cape Town, I wouldn’t have believed them,” writes astrophysicist Hakeem Oluseyi in his inspiring memoir A Quantum Life. The book follows his “unlikely journey from the street to the stars”.
Born James Edward Plummer Jr, Oluseyi was often uprooted as a child, and learned to survive in some of the toughest urban neighbourhoods across the US. He also lived in rural Mississippi, a state where older African American people still addressed white people, including children, as “ma’am” and “sir”.
“Albert Einstein and I would have been friends,” he recalls thinking when he read about the scientist. Einstein, too, was told to “stop staring into space”, and his family moved often. He also featured when Oluseyi taught himself to program at high school. He coded concepts of Einstein’s theory of special relativity into a game and won first place in physics in the Mississippi State Science Fair.
To fund college, he joined the navy. But after two years, he was discharged with atopic dermatitis, which barred him from serving on ships. An old friend encouraged him to enrol at Tougaloo College in Jackson, Mississippi. The pair sold drugs there and dropped out, but Oluseyi re-enrolled.
This time, David Teal, a white, Harvard-educated professor in the historically Black college, took an interest in Oluseyi, urging him to attend a meeting of African American physicists at the Massachusetts Institute of Technology. The experience felt like an “alien abduction”, writes Oluseyi, but it gave him a clear goal: to apply to graduate programmes.
“Every year,” he writes, “the Stanford physics department took in one student like me – a diversity admission who wasn’t at the same level of academic preparation as the rest of the class.” It would take a lot more than hard work alone to earn his PhD there, but he was up for the challenge (and later a change of name).
“It would take a lot more than hard work to earn his PhD, but Hakeem Oluseyi was up for the challenge”
Besides, his doctoral adviser was Arthur B. C. Walker. The African American astrophysicist, whose telescopes gave unprecedented views of the sun, had mentored students from under-represented groups in physics. Sally Ride, the first US woman in space, was his first doctoral student.
Walker told Oluseyi that some still believed that while Black scientists could build ingenious gadgets, they weren’t gifted enough to make insights in pure physics or in the analyses of data and observations. While Walker got credit for his novel technology to study the sun, doubters said he had few pure science publications. Oluseyi worked with his mentor to seal his legacy before Walker died in 2001.
Today, Oluseyi is one of a handful of Black astrophysicists, but he has been working to change that. In 2008, he received a grant from the Kellogg Foundation to set up a mentoring programme for Black astronomy students in South Africa. They were brilliant, but felt second-class at university, says Oluseyi. He shared his struggles as he taught the students advanced topics. They passed in the top 20 per cent of the class.
South Africa will eventually co-host the Square Kilometer Array (SKA), the world’s most powerful radio telescope cluster. Four of Oluseyi’s students are in the front row of a SKA team photo. He wasn’t there, but says “believe me, I’m standing tall and proud… next to them”.
