Society tries to shame us for growing old. But we should think of it as a rite of passage when our character comes throughThere is still sex in the city, beyond the age of 50. But it may come at a price that makes you wonder if it’s really worth it. Or at least, according to the writer behind the cult of Carrie, Samantha, Charlotte and Miranda.Candace Bushnell’s latest novel-cum-memoir returns once more to her favourite stamping ground, that tiny and exhausting pool of wealthy New York women who will do absolutely anything to stay in the game. Only now they’re older, spending their money not on cocktails but on face creams and fillers, all while debating the merits of undergoing vaginal laser surgery so that the naturally ageing insides of their bodies don’t give the lie to their artificially preserved exteriors.

During our summer break, we’re revisiting the archives. Today, Wildlife recordist Chris Watson begins a three-part journey into the sonic environment of the ocean, celebrating the sounds and songs of marine life and investigating the threat of noise pollutionFirst released: 03/05/2019Contrary to popular belief, and the writings of Jacques Cousteau, life beneath the ocean surface is not a silent world but a dense and rich sonic environment where sound plays a fundamental role in life.In episode one of this three-part series, pioneering nature sound recordist Chris Watson begins a journey inspired by his fascination with recording the songs and signals of life under the ocean surface. He will meet scientists examining the possible impacts of noise pollution from the likes of shipping noise and seismic explosions used in the search for oil and gas. He will also talk to sound artists trying to raise awareness of the issue through their art. Continue reading...

Extra thrust from reflective sail on tiny craft changed shape of its orbit by about 2km, scientists reportA crowdfunded spacecraft has successfully sailed on sunlight while in orbit around the Earth.LightSail 2 was launched in June by the space advocacy group the Planetary Society as a secondary payload on a SpaceX Falcon Heavy rocket.

In its crucial land and climate report, the IPCC irresponsibly understates the true carbon cost of our meat and dairy habitsIt’s a tragic missed opportunity. The new report on land by the Intergovernmental Panel on Climate Change (IPCC) shies away from the big issues and fails to properly represent the science. As a result, it gives us few clues about how we might survive the century. Has it been nobbled? Was the fear of taking on the farming industry – alongside the oil and coal companies whose paid shills have attacked it so fiercely – too much to bear? At the moment, I have no idea. But what the panel has produced is pathetic.The problem is that it concentrates on just one of the two ways of counting the carbon costs of farming. The first way – the IPCC’s approach – could be described as farming’s current account. How much greenhouse gas does driving tractors, spreading fertiliser and raising livestock produce every year? According to the panel’s report, the answer is around 23% of the planet-heating gases we currently produce. But this fails miserably to capture the overall impact of food production.

Nasa’s first flight director who controlled the Apollo moon landingsThe engineer Chris Kraft, who has died aged 95, was Nasa’s first flight director, the man who shaped the team – and the control centre – at Cape Canaveral in Florida and, from 1963, in Houston, Texas. Kraft’s work spanned the era from Nasa’s first faltering manned missions during the space race of the 1960s to the space shuttle in the 80s.He was director of flight operations at Nasa when Neil Armstrong and Buzz Aldrin made their moon landing in Apollo 11 on 20 July 1969, and signed off with the Apollo 12 mission that November. He returned in 1970 to chair the crisis meeting as the crippled Apollo 13 limped back to Earth. Continue reading...

Previously undiscovered group of molecules found to be behind phenomenonThe secret behind the eerie glow of two shark species has been revealed in a study which sheds light on the origin and possible advantages of their fluorescent green bodies.Chain catsharks and swell sharks are deep-dwelling and live in the western Atlantic and eastern Pacific respectively, where they hide among rocks and rubble. While at first glance they appear to be in various shades of brown, recent studies have shown that under blue light they glow green. Crucially, only blue light penetrates the depths of the ocean.

Potential impacts of rise in vertical shear include longer, bumpier and dearer flightsThe climate crisis could be making transatlantic flights more bumpy, according to research into the impact of global heating on the jet stream.Jet streams are powerful currents of air at the altitudes which planes fly. . They result from the air temperature gradient between the poles and the tropics, and reach speeds of up to 250mph (400kmph). They also sometimes meander. Continue reading...

US study finds link between number of restaurants and higher BMI

Giant bird estimated to have weighed about 7kg has been named Heracles inexpectatusFossils of the largest parrot ever recorded have been found in New Zealand. Estimated to have weighed about 7kg (1.1st), it would have been more than twice as heavy as the kākāpo, previously the largest known parrot.Palaeontologists have named the new species Heracles inexpectatus to reflect its unusual size and strength and the unexpected nature of the discovery.

Scientists have observed up to 10cm of salt falling to sea floor every year since 1979Try swimming in the Dead Sea and you can’t help but float. This salt lake, bordered by Jordan, Israel and the West Bank, is nearly 10 times as salty as the oceans. In recent decades diversion of freshwater streams has made it even saltier, and since 1979 scientists have observed salt crystals “snowing” down, depositing up to 10cm on the sea floor every year. It’s the only place in the world where this happens and now scientists think they know why.During summer the Dead Sea separates into two layers: a warm super-salty layer sitting above a cooler less-salty layer. The research, published in Water Resources Research , shows that when small waves break this boundary they encourage salty fingers to penetrate into the lower layer. Warm water holds more salt than cool water, so as the fingers cool they produce salt crystals which then rain down on the sea floor. Continue reading...

Experts call for urgent action to tackle ‘biggest health crisis of our time’Dementia is the biggest health crisis of our time, experts have said, as statistics show the condition was the primary cause of death in England and Wales last year.Almost one in eight people died from dementia and Alzheimer’s disease in 2018, with the proportion increasing for the fourth consecutive year – up from 12.7% in 2017 to 12.8% in 2018. There were 541,589 deaths registered in England and Wales last year, the highest total since 1999. Continue reading...

Scientists believe the Beresheet’s unusual cargo may be alive and well on the moonThe odds of finding life on the moon have suddenly rocketed skywards. But rather than elusive alien moonlings, the beings in question came from Earth and were spilled across the landscape when a spacecraft crashed into the surface.The Israeli Beresheet probe was meant to be the first private lander to touch down on the moon. And all was going smoothly until mission controllers lost contact in April as the robotic craft made its way down. Beyond all the technology that was lost in the crash, Beresheet had an unusual cargo: a few thousand tiny tardigrades, the toughest animals on Earth. Continue reading...

Daniel Freedman, Peter van Nieuwenhuizen and Sergio Ferrara developed landmark theory in 1970sThe most lucrative prize in science has been awarded to three researchers for a landmark theory that married particle physics with Einstein’s description of gravity, and proposed a candidate for the mysterious cosmic goo known as dark matter to boot.Daniel Freedman, Peter van Nieuwenhuizen and Sergio Ferrara, from the US, the Netherlands and Italy respectively, developed “supergravity” in the 1970s, a mathematical feat that wrapped Einstein’s general relativity into a speculative theory of all the known particles in the universe.

Mindfulness may have become a tool of capitalism, but if it works, does it matter?In a frequently quoted passage, the American professor of medicine Jon Kabat-Zinn defines mindfulness as “a way of being in a wise and purposeful relationship with one’s experience… cultivated by systematically exercising one’s capacity for paying attention, on purpose, in the present moment and non-judgmentally”. It sounds harmless enough. But San Francisco-based academic Ronald Purser thinks not. He has written a strident polemic attacking the secular mindfulness movement.Forty years ago, Kabat-Zinn set about distilling Buddhist wisdom into a framework that could address modern concerns. He originally designed a short course for people suffering from chronic physical pain. These programmes have since been extended to treat a wide range of cases including depression, addiction and workplace stress. They have been adopted in schools, businesses, criminal justice systems, in the US military, the NHS and UK parliament. Unless you’ve been living under a rock, you are likely to have encountered them. Continue reading...

The technology can also be used to identify poisons as well as to monitor riversBeing palmed off with a young whisky when expecting an 18-year-old single malt can be a glass-half-empty moment. But now scientists have developed an “artificial tongue” that might make such skulduggery a thing of the past.The team, based in Scotland, say their device can be used to tell apart a host of single malts – a move they say might help in the fight against counterfeit products.

Researchers find usage boosts positive feelings towards women and LGBT peopleMore than 100 failures litter the battleground that is the hunt for an English gender-neutral singular pronoun. From thon, ip and hiser to hem, ons and lers, the discarded terms have piled up since the mid-19th century.But the quest for the right word is not in vain, a new study suggests. Using a gender-neutral pronoun, it found, reduces mental biases that favour men, and boosts positive feelings towards women and LGBT people. Continue reading...

Scientists say bones formerly identified as Massospondylus are from a different speciesFossil hunters have discovered a new species of dinosaur that has been hidden in plain sight in a South African museum collection for 30 years.The fossilised bones had been misidentified as a peculiar specimen of Massospondylus, one of the first named dinosaurs.

Suffolk site reopens enhanced with 27-metre ship sculpture, seventh-century treasures and immersive exhibitionsEighty years ago this summer, a beautifully situated if unusually lumpy field in Suffolk became, briefly, the site of an archaeological sensation.An immense Anglo-Saxon ship burial had been uncovered, loaded with some of the most astonishing gold and jewelled artefacts ever found. But the looming outbreak of war in July and August 1939 meant that Sutton Hoo’s greatest treasures were hastily dug out of the ground and packed off to anonymous safety in a London tube station, later to become some of the most iconic exhibits of the British Museum.

Our largest planet and the red supergiant are close together in the south-eastern sky, joined on Wednesday evening by the moonThere is an interesting trio of celestial objects to look out for on the evening of 8 August. The mighty planet Jupiter is currently close to the red giant star Antares in the constellation Scorpius. On 8 August, this pair will be joined by the moon. The chart shows the view looking south-south-east at 22:00 BST that evening. The moon will be on the fringes of Libra, the scales, preparing for a very close pass to Jupiter one night later. Giving the close pass an added aspect is the proximity of the beautiful red star Antares, a star so large that if it were to replace the sun in our solar system, its surface would be somewhere between the orbits of Mars and Jupiter. Looking further to the south, pale Saturn will be nestled in Sagittarius, the archer. There is also a dawn treat for early risers. Mercury will reach its further distance from the Sun in the morning sky this week. Watch out for a bright, steady “star” low in the brightening eastern sky. Continue reading...

Cutting carbon from transport and energy ‘not enough’ IPCC findsAttempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week.A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless there is also a transformation in the way the world produces food and manages land.

It’s time to stop being mealy-mouthed about this. No more silent passes to climate science deniersOver the past couple of weeks things have been happening on the climate change front but, unfortunately, little is changing in parliament, where the government’s direct action policy has continued to be an utter failure and a Queensland LNP MP suggested in his first speech in the House of Representatives that schools should teach both sides of the climate change debate in school – to prevent them being “brainwashed with extreme left or right ideologies”.Related: Greta Thunberg hits back at Andrew Bolt for 'deeply disturbing' column Continue reading...

The cardiologist on why we should take heart disease more seriously, advances in treatment and how you really can die from a broken heartHaider Warraich is a cardiologist at Duke University Medical Center in Durham, North Carolina. His medical training began in his native Pakistan, and this autumn he will join the faculty of Brigham and Women’s hospital at Harvard Medical School and the VA Boston (Department of Veterans Affairs medical facilities). In his book State of the Heart, he looks at the history, science and future of cardiac disease, and argues that it has become an overlooked condition.People are more likely to survive a heart attack today, but heart disease is still the biggest killer worldwide. Why is that?

As well as joys, challenges and unusual pets she brought fresh insights to our homeAbout five years ago a friend at my son’s school, a girl of 14 I’d only met once before (and liked very much, with her big eyes and cheeky smile) got herself into something of a crisis, and as a result of a breakdown in her home life, came to live with us. I hadn’t been looking to add another child to the family. We had our son at home, also 14, and my older son, aged 25, from a previous relationship was finally moving out. Suddenly, at 52, right when I thought I was done with mothering, I had a brand new teenage daughter.The social workers asked me the most prying questions Continue reading...

It’s not just his destructive Brexit stance, his values are entirely opposed to oursThe Daily Express is calling it “the Boris effect”. Johnson’s election has reportedly caused a “record jump” in the polls for the Conservative party, with the Telegraph gleefully reporting that its prized former columnist has received the largest bounce of any Conservative leader in the past two decades.Though Tory hopes were dented by the party’s defeat in Thursday’s Brecon and Radnorshire by-election, supporters still believe Johnson is capable of winning a general election – which could happen within months.

Researchers reprogrammed human cells before injecting them in the monkey embryoEfforts to create human-animal chimeras have rebooted an ethical debate after reports emerged that scientists have produced monkey embryos containing human cells.A chimera is an organism whose cells come from two or more “individuals”, with recent work looking at combinations from different species. The word comes from a beast from Greek mythology which was said to be part lion, part goat and part snake. Continue reading...

Castle Howard, North Yorkshire: A trick of the light evokes the prehistoric shaman’s powerWhen the Wild Hunt erupts from the pages of Susan Cooper’s magnificent novel The Dark Is Rising, the throng is led by the towering, antlered figurehead of Herne the Hunter. It’s cacophonous, end-of-days stuff – enough to leave any 10-year-old wild-eyed. I next encountered Herne in shamanic guise, swathed in dry ice mist and spookily backlit in the 1984 TV series Robin of Sherwood. With the words, “Nothing’s forgotten, nothing is ever forgotten,” he took firm root in my teenage psyche.There’s not a whiff of dry ice today. The woods are warm and flickering with butterflies. And yet before my very eyes, an antlered form is emerging, larger than life, from the forest floor, with a metre-long head and a spark of life dancing in the huge dark eye. Continue reading...

Being socially active in 50s and 60s linked to lower risk of illness later in life, researchers say

Pew survey shows rise in confidence that scientists will act in public’s interestScientists have topped a survey of trusted professions, with adults in the US more confident that they act in the public’s best interests than employees from any other line of work studied.The survey found that confidence in scientists has risen markedly since 2016 and more than half of American adults believe the specialists should be actively involved in policy decisions surrounding scientific matters.

Scientists say July at least equalled and may have beaten hottest month on recordThe record-breaking heatwave that roasted Europe last month was a one-in-a-thousand-year event made up to 100 times more likely by human-driven climate change, scientists have calculated.Around the globe, July at least equalled and may have surpassed the hottest month on record, according to data from the World Meteorological Organization. This followed the warmest June on record. Continue reading...

US scientists say their blood test can be 94% effective in spotting those at risk of the illnessA blood test that can detect signs of Alzheimer’s as much as 20 years before the disease begins to have a debilitating effect has been developed by researchers in the US.Scientists at the Washington University School of Medicine in St Louis in Missouri believe the test can identify changes in the brain suggestive of Alzheimer’s with 94% accuracy, while being much cheaper and simpler than a PET brain scan.

The rage inducing, sober reality of it, you could do it but you won’t

Mass extinctions, carbon emissions and freak storms will feature at a festival where artists are finding new ways to raise the alarm‘I no longer think of this as a technological problem. I don’t think of it as a political problem.” Alanna Mitchell is assessing the climate emergency. “I think of it as a cultural problem.” The Canadian journalist and playwright believes the arts play a key role in transforming public opinion. “That’s the way humans understand the world,” insists Mitchell. “We understand it in terms of narrative.”Some of the most successful environmental activism has used theatrical or artistic gestures to capture imaginations. Think of Extinction Rebellion’s dramatic funeral marches, or Liberate Tate’s oil spill installations. At the Edinburgh festival this month, theatre-makers are bringing the crisis to the fore, from drawing the links between colonialism and the changing climate in Kiinalik: These Sharp Tools to Tom Bailey’s meditation on the sixth mass extinction in Vigil.

Langstone, Hampshire: Potential mates can detect the emergence of an adult vapourer moth from miles awayIt was impossible to miss the rusty tussock moth (Orgyia antiqua) caterpillar foraging on my raspberry bush. Its body was dotted with orangey-red pinacula, wart-like growths sprouting clusters of pale lemon hairs. It had two bristly black antler-like protrusions at the front of its head, and a tail-like projection from its rear. Along its back four sulphur-yellow dorsal tufts stood proud, like the bristles of an interdental toothbrush. Measuring it at 25mm in length, I could tell it was a female, as males reach a maximum of about 15mm.These caterpillars are polyphagous, feeding on a wide range of deciduous trees and shrubs, so I potted up a selection of raspberry, blueberry, hazel and birch, and introduced her to a rearing cage. After five days of feasting, she stopped eating and spun a cocoon on the underside of a hazel leaf. Over the course of a week I squinted through the web of silken threads, watching the silhouette of her larval body melting and morphing into adult form. Continue reading...

Our galaxy is like a distorted disc, study based on Cepheid stars confirmsThe most detailed three-dimensional map yet of the Milky Way has been revealed, showing that our galaxy is not a flat disc but has a “warped” shape like a fascinator hat or a vinyl record that has been left in the sun.“The stars 60,000 light years away from the Milky Way’s centre are as far as 4,500 [light years] above or below the galactic plane – this is a big percentage,” said Dr Dorota Skowron of the University of Warsaw, first author of the latest research.

My friend Robert Young, who has died aged 83, was a psychotherapist, writer and academic, the author of influential books on Darwin, psychoanalysis and the history of ideas. A brave man of the left, he founded several journals of radical inquiry into science and psychoanalysis, and became a book publisher.Born and raised in Dallas, Texas, Bob was the son of Harold Young, who worked for a cotton filtering machinery company, and his wife, Suzanne (nee Jamison). At Highland Park high school and in the surrounding community, he rubbed shoulders with oil barons’ offspring, whose social attitudes repelled him. Continue reading...

Record temperatures in Europe and the US have reinforced the danger of global heating for many inhabitants. But others are and will be far worse hitWe tend to learn better from experience than from what we have simply been told. So for many in Europe, sleepless nights and suffocating buses or workplaces have helped to make real the threat posed by global heating. Now statistics are reinforcing the message. Last week the UK had the hottest day on record: 38.7C in Cambridge. New records were set in Germany, Belgium and the Netherlands in July, and June was the hottest month in US history. The Met Office says that the UK’s 10 hottest years on record have all been since 2002.Heatwaves naturally occur in summer, but they did not used to be so hot, or so frequent. Experts say that the UK’s sweltering weather last summer was made 30 times more likely by global heating. That link has sunk in: in a new survey, 77% believed the recent heatwave was partially or wholly caused by the climate crisis. As temperatures reach unprecedented levels, so does public concern about the environment. Continue reading...

We study disaster preparedness, and ‘climate change’ is far too mild to describe the existential threat we face

Researchers say tick-borne disease ‘is everywhere’ with 8,000 diagnoses likely in 2019

Rod Schoonover, who was an intelligence analyst for 10 years, said the Trump administration halted his report on global heatingA former senior government analyst has accused the Trump administration of “undercutting evidence” of the threat to national security from the climate crisis after his report on the issue was blocked by the White House.Rod Schoonover, who worked as an intelligence analyst for the federal government for 10 years before resigning earlier this month, submitted a written testimony on the “wide-ranging implications” of global heating over the next 20 years, for submission to the House intelligence committee last month.

The concept has changed the way we think about everything from autism to homelessness. But it has its drawbacksBlack and white thinking may die hard, yet never has society been quite as comfortable with the concept of the spectrum than the present.According to researchers at Merriam-Webster, use of the word “spectrum”, in a wide range of contexts, has grown dramatically within the current decade. Coined by Isaac Newton in 1672 to describe refractions of light, today referencing a “spectrum” is almost always shorthand for acknowledging a metaphorical range of nuances. Continue reading...
