How absorbing your concentration in needlework relieves inner turmoilI grew up in post-war Britain when, saved from German invasion – men returned from war, children from evacuation, families were reunited – the comfort of the home became paramount. Its importance was marked out in sewn domestic niceties: embroidered tray cloths, cheval sets and tea cosies. My home had a sewing machine in the corner, an ever-ready sewing workbox by my mother’s chair and a box that brimmed with buttons for us children to rifle through by way of entertainment. This was my material world.Living in industrial Glasgow, a city grimed with soot, smog and smoke, my landscape was monochrome until the day, when I was about six years old, my mother took me to an Aladdin’s cave in the city centre. There she bought me linen cloths already stamped with floral flourishes, packets of gold-tipped needles and silver scissors with handles shaped like a bird’s wings – and she let me choose loops of embroidery threads from a carousel of colours that dazzled me.

Exclusive: a fifth of 13- to 15-year-olds ‘spend five hours or more a day on social media’Teenagers in Britain may be putting their health and education at risk by spending too much time on social media at bedtime, according to a major study into adolescent sleep habits.More than a third of teenagers spent at least three hours a day on social media, with a fifth devoting at least five hours to the activity, researchers found. Those who were on social media for three hours or more daily were most likely to get to sleep late. Continue reading...

As a teacher, how do I show my pupils the right values when they see so little of it from their adult ‘role models’?The children’s climate strike has become another lightning rod in the never-ending culture war. Those on the left applauded them for their brave moral stand. Jonathan Freedland – not without basis – pointed to the strike as evidence that children were acting more like adults than the adults. But on the right the focus seemed to be on chiding them and telling them to get back to school – from the prime minister’s spokesperson to Toby Young, who saw the children’s behaviour as an argument for raising the voting age to 21.So far, so predictable. And then came the waves of abusive comments and tweets in response. Teachers who “support this strike should have their assets confiscated and [be] sent to work down the salt mines”. “Oh do shut up you total fucking arse” the actor James Purefoy tweeted at Young to his 107,000 followers.

With the Large Hadron Collider reaching its upper limits, scientists around the world are drawing up plans for a new generation of super colliders. Ian Sample weighs up whether or not the potential new discoveries a collider may make will justify the cost of building them.Cern recently announced a proposal to build a machine that would dwarf the Large Hadron Collider.It could cost around $12bn. But Cern isn’t the only lab looking at building such a monster machine.

Pattern seems to confuse flies, researchers who dressed horses up as zebras findThe mystery of how the zebra got its stripes might have been solved: researchers say the pattern appears to confuse flies, discouraging them from touching down for a quick bite.The study, published in the journal Plos One, involved horses, zebras, and horses dressed as zebras. The team said the research not only supported previous work suggesting stripes might act as an insect deterrent, but helped unpick why, revealing the patterns only produced an effect when the flies got close.

Molecular geneticist who was a leading contributor to the Human Genome ProjectIn 2003 the Human Genome Project (HGP) published the complete sequence of human DNA. Sue Povey, who has died aged 76, contributed greatly to this international collaborative project with her team at University College London, her work as a molecular geneticist having started much earlier, in the late 1960s. She was motivated throughout by a strong interest in people and disease.At the outset she exploited newly developed enzyme detection systems that revealed differences between individuals and among species, allowing her to solve a number of longstanding puzzles. One was mapping the chromosomal location of human genes, initially by family studies, which use inheritance patterns across the generations, like Gregor Mendel’s pioneering work, to identify closely linked genes. Later mapping used human-mouse hybrid cell culture. In this approach, genes are assigned to specific human chromosomes by observing their coordinated presence or absence. Continue reading...

After endless guides to self-help, a new wave of books spearheaded by The Little Book of Bad Moods is switching the focus to more realistic hopesAlthough Finnish doesn’t have a direct equivalent of English’s “mustn’t grumble”, Lotta Sonninen admits, it has a few equivalents. “Vali vali” comes from “valittaminen”, meaning complaining: but there is also “marina”, “kitinä” and “jupina” (to complain under your breath or through gritted teeth); “urputtaminen” (to complain to someone about something they did); “nillittäminen” (to complain at length); and “avautuminen” (to complain at length with unnecessary frankness). Sonninen is familiar with them all; she has spent years working in the Finnish publishing industry, poring over positivity handbooks designed to get her countrymen through the long dark winters.“The type of books that crossed my path ask you to find the joy in the little things of life and turn up the silver lining or the bright side,” Sonninen says. “Although one at a time they’re really cute, when there were several of them it started looking a bit comical. So I ended up imagining an antidote.” Continue reading...

‘Centres of decision making’ will be targeted if west deploys new missiles in EuropeVladimir Putin has said that Russia will develop new weapons and aim them at western “centres of decision-making” if the west deploys new short and medium-range missiles in Europe.The threat, which appears to describe Washington and other western capitals, came after the United States and then Russia suspended compliance with the 1987 Intermediate-Range Nuclear Forces treaty.

Attempt to become fourth country to send spacecraft to the surface blasts off this weekA team of Israeli scientists is to launch what will be the first privately funded mission to land on the moon this week, sending a spacecraft to collect data from the lunar surface.Named Beresheet, the Hebrew word for Genesis, the 585kg (1,290lb) robotic lander will blast off from Florida at 01.45 GMT on Friday, propelled by one of Elon Musk’s SpaceX Falcon 9 rockets. Once it touches down, in several weeks, it will measure the magnetic field of the moon to help understand how it formed. Continue reading...

If we want to make progress with FGM, we need to first tackle our outdated, misogynistic views on sexThe first UK conviction for female genital mutilation (FGM) this month was a milestone in the fight for the basic human rights of women and girls. But one of the things that stands out from the news reports of that case is how oddly furtive they were about communicating the key facts – in particular their avoidance of the C-word: clitoris.In reporting such a prominent case, are readers unable to be shown the correct medical terminology? Why do the media carefully avoid mentioning what occurred, using highly generalised anatomical terms before quickly moving on? If this lack of detail was to spare the victim the indignity of having such a personal matter discussed so publicly, I would have sympathy, however I do not think that this is the case here. What I think is at play, is a deep-rooted fear of the clitoris. Continue reading...

Millions of cases could be prevented with high HPV vaccine and screening coverageCervical cancer could be effectively eliminated in most countries around the world by the end of the 21st century, according to research.The HPV (human papilloma virus) vaccine, which protects against the virus that causes most cases, has dramatically reduced incidences of cervical cancer wherever uptake has been high. There are hopes that the jab given to young girls, together with occasional HPV screening, could end the scourge of a disease that kills more than 300,000 women globally every year.

Archaeologists say up to 80 two-ton blocks may have been dragged from Preseli hillsThey are among the most famous and most enigmatic mysteries in all of archaeology: how did neolithic builders, using only stone, wooden and bone tools, carve Stonehenge’s bluestone pillars from the hilltops of western Wales – and how on earth did they transport them more than 230km (143 miles) to Salisbury plain?Now, an excavation has found intriguing new evidence of the method by which the huge stones were chiselled out of the rock face at two craggy outcrops of the Preseli hills in Pembrokeshire.

Once we were pressured to acquire things and do more with our lives. Now, we’re being told to declutter our homes and diaries. What happened to just being ourselves?What brings you joy? It is a question that is hard to avoid these days, as joy seems to be the new buzzword. It is on the cover of two new books, The Joy of No (#Jono) by Debbie Chapman, published at the end of last year, and The Joy of Missing Out, by the philosopher and psychologist Svend Brinkmann, published earlier this month. It is also on Netflix, in the show Tidying Up with Marie Kondo, in which the decluttering guru and author tells us to discard any possessions that do not “spark joy”. Truly, a surfeit of joy!But joy is not the only idea linking these three approaches: Chapman, Brinkmann and Kondo all tap into the same zeitgeisty wish to clean up our cluttered lives. For Kondo, it is about household clutter; for Chapman and Brinkmann, it is life clutter. Continue reading...

Australian Academy of Science panel says urgent steps needed to restore flowsA scientific panel investigating the causes of three mass fish deaths at the Menindee lakes has pointed the finger squarely at those managing the Murray-Darling river system, saying the lack of flows was caused by a combination of drought and over-extraction, leading to the environmental disaster.Up to one million native fish, including hundreds of thousands of small bony bream, Murray cod, up to 20 years old, and silver perch were killed in the three events. While there had been other fish kills during droughts, these were on an unprecedented scale, the report found. Continue reading...

The philosopher Giordano Bruno, burned for heresy in 1600, has become a symbol of free expression and toleranceEvery year on 17 February, a crowd gathers in Rome’s Campo de’ Fiori to place wreaths, poems and candles at the foot of the statue that glowers towards the Vatican from beneath its friar’s cowl. The man it memorialises, the Neapolitan philosopher Giordano Bruno, was burned alive by the Inquisition on that spot in 1600, for heresies including several books in which he advocated the heliocentric cosmology of Copernicus and argued that the universe was infinite and contained multiple other worlds.Related: Cosmos and Giordano Bruno: the problem with scientific heroes | Rebekah Higgitt Continue reading...

It has a sad and misunderstood history, but witchcraft still has a role to playOur fascination with witches has long surpassed witchcraft being a crime punishable by death. They are a cultural obsession, it seems, that is always with us in one guise or another. In recent weeks it’s been Netflix’s reboot of Chilling Adventures of Sabrina and Sky One’s A Discovery of Witches, as well as an episode of Doctor Who focusing on the Pendle witch trials. The only shift has been packaging witchcraft as a more grown-up take on women attempting to take control of their own destinies.As a teenager, my friends and I were self-subscribed members of Wicca, the “white witch” religion. Growing up in a rainy mill town in Lancashire, with little in the way of diversion, our cultural diet consisted of Heathers, The Craft and other moody 90s films. At sleepovers we did Ouija boards and whispered “light as a feather, stiff as a board” as one of us lay corpse-like on laced hands, her arms crossed over her chest. Later, I’d lie awake as the wind and rain battered down from the moor, thinking of the guns my friend’s father kept hanging in the hallway. Continue reading...

As a young doctor in rural South Africa (1975-76), my father, Julian Pratt, questioned the underlying cause of the diseases he was treating and identified how the grossly unequal distribution of land for agriculture was having a devastating effect. As a result, he became passionate about land reform and pursued this interest for the next 40 years.Julian, who has died aged 70, researched, proposed and campaigned for a radical approach to the market economy, replacing private ownership of land with a system he described as stewardship. He built on work by Thomas Paine and Henry George, and advocated that everyone should be entitled to an equal share of the wealth of the natural world. In a stewardship economy, “stewards” would pay a fee (a land tax) for the exclusive right to use land. The fee, gathered by government in place of conventional taxes, would be used to provide a universal basic income and fund public services. He outlined his ideas in a book, Stewardship Economy: Private Property Without Private Ownership (2011) and on his website, www.stewardship.ac. He described how the transition to a stewardship economy could be made, and last year contributed to a Liberal Democrat policy paper, Taxing Land, Not Investments (2018). Continue reading...

I’ve seen how OpenAI’s GPT2 system can produce a column in my style.

Across the country today, children left their classes to protest against climate change. This is my message to themThe Youth Strike 4 Climate gives me more hope than I have felt in 30 years of campaigning. Before this week, I believed it was all over.

Now, for the first time in years, I think we can turn them around.Related: Schoolchildren take to streets in UK-wide climate strike - live Continue reading...

What do attempts to establish a human colony on Mars, a $9bn blood-test startup and the Fyre festival have in common? Sheer chutzpahIf you were hoping to escape Brexit Britain with a one-way ticket to Mars, I am afraid you’re out of luck. Mars One Ventures, the company that wanted to start a permanent human settlement on the red planet in the next few years, has gone bankrupt, although its not-for-profit sister company, the Mars One Foundation, continues to operate. No doubt you are as shocked by this as I am.A quick recap of the space saga: Mars One was launched in 2012, when the Dutch entrepreneur Bas Lansdorp decided that, instead of dealing with his midlife crisis by getting a motorcycle, he would colonise the fourth planet from the sun. How he planned to do this was questionable, as Mars One didn’t make any space technology. It was a bit like the Brexit ferry firm that didn’t own any ferries, but on an interplanetary scale. Also unclear was how he thought Mars One could start a space colony on a budget of just $6bn; Nasa has estimated that a manned mission to Mars would cost between $80bn and $100bn (£62bn and £78bn). Mind you, Nasa clearly wasn’t doing the sort of galaxy-brain thinking Lansdorp was: the entrepreneur had the brilliant idea of making a reality show out of the colonisation process to fund the endeavour. After all, who wouldn’t want to watch a space-based mashup of Love Island and Lord of the Flies? Continue reading...

Simply telling people they are ignorant has failed. We need to find a better way to communicateAfter reading the news that cases of measles have soared by 50% in the last year, I recalled the first time I heard an anti-vaccination conspiracy theory. It wasn’t from a member of Donald Trump’s administration, or part of a frenetic, grammatically challenged Facebook post – it was from a classmate when I was at school. Her family wasn’t waging a crusade against medical science: they simply gave credence to disgraced former doctor Andrew Wakefield’s study that wrongly asserted a link between the MMR vaccine and autism. Back then, the study had not yet been discredited.One only has to stray into anti-vaxxer internet forums for a few minutes to see that they’re stuffed with conspiracy theorists, opportunists, reactionaries, and – worst of all – hubristic idiots. This is the vanguard of the anti-vaxxer movement. But behind that vanguard are a lot of concerned parents who are being convinced of wild and dangerous ideas because we – and by we, I mean those of us who recognise the incontrovertible fact that vaccines are essential – aren’t talking to them properly. A number of the anti-vaxxer vanguard may have started life as concerned parents, but have gradually sunk into increasingly extreme positions because the only communication they’re getting from the other side is that they’re foolish and irresponsible. Almost every week the internet produces another diatribe against anti-vaxxers, or a listicle of their “horrifyingly stupid” social media posts. Continue reading...
