As discussed: it’s time to break the hateful passive-aggressive email chain | André Spicer
Phrases like ‘sorry for the double email’ or ‘please advise’ only serve to enrage – why use them?Remember the last time you were scrolling through an email and saw phrases like “Reattached for your convenience”, “sorry for the double email” or “please advise”? You’re not alone if you felt enraged by reading them. According to a recent survey by the software company Adobe, 25% of us loathe the phrase “not sure if you saw my last email”. The No 2 most hated phrase was “as per my email”. In fact, the nine most loathed phrases in emails all had one thing in common: passive aggression.Passive aggressive behaviour is a frequent complaint in the workplace. It was coined by William Menninger, a colonel in the US army in 1945. Writing in a technical bulletin, he described soldiers as passive aggressive when they would wilfully shirk duties by not carrying them out competently. They expressed their hatred of assigned tasks by “passive measures such as pouting, stubbornness, procrastination, inefficiency and passive obstructionism”. Menninger thought such behaviour was a sign of immaturity and a reaction to “routine military stress”. Continue reading...
A no-deal Brexit will betray British science
With more than £500m a year at stake, the scale of losses to UK research from a no-deal Brexit are becoming clearOn 14 June 2016, just over a week before the EU referendum, Vote Leave were keen to calm the fears of British scientists, farmers and others who relied on European funds. The thirteen Vote Leave ministers signed a pledge, still standing on Vote Leave’s website, that “If the public votes to leave on 23 June, we will continue to fund EU programmes in the UK until 2020.” One of those thirteen signatories was Dominic Raab.How ironic then, that one of the first things Dominic Raab did as the newly-appointed Brexit Secretary was to suggest, on 21 July 2018, that the UK might not honour the hard-wrangled withdrawal agreement that guarantees continued funding of EU programmes until 2020.

The case against Mars colonisation
Plans are being made to colonise Mars. Zahaan Bharmal unpicks the arguments against the ideaEarlier this month, a group of 60 prominent scientists and engineers met behind closed doors at the University of Boulder Colorado. Their agenda: Mars colonisation.Organised by Elon Musk’s SpaceX and attended by members of Nasa’s Mars exploration programme, the goal of this inaugural “Mars workshop” was to begin formulating concrete plans for landing, building and sustaining a human colony on Mars within the next 40 to 100 years.

How to be human: the man who was raised by wolves
Abandoned as a child, Marcos Rodríguez Pantoja survived alone in the wild for 15 years. But living with people proved to be even more difficult.By Matthew BremnerThe first time Marcos Rodríguez Pantoja ever heard voices on the radio, he panicked. “Fuck,” he remembers thinking, “those people have been inside there a long time!” It was 1966, and Rodríguez woke from a nap to the sound of voices. There was nobody else in the room, but the sounds of a conversation were coming from a small wooden box. Rodríguez got out of bed and crept towards the device. When he got closer, he couldn’t see a door, a hatch, or even a small crack in the box’s surface. Nothing. The people were trapped.Rodríguez had a plan. “Don’t worry, if you all move to one side, I’ll get you out of there,” he yelled at the radio. He ran towards the wall at the other end of the room, the device in his hand. There, breathless and red in the face, he held it high above his head and brought it down hard against the brick wall, in one violent swing. The wood splintered, the speaker popped out of its casing, and the voices fell silent. Rodríguez dropped the radio on to the floor. Continue reading...
Anaemia drugs could also aid recovery after heart attack, says study
Findings suggest trial drugs may reduce chance of heart failure for diabetic patientsHopes have been raised that drugs being trialled to treat anaemia could also be used to aid recovery after a heart attack and help decrease the chance of future heart failure.Initial results suggest the drugs could be given to people with Type 2 diabetes immediately after a heart attack, according to research funded by the British Heart Foundation (BHF) and Diabetes UK.

Climate change will make hundreds of millions more people nutrient deficient
Crops grown in a high CO2 atmosphere are less nutritious, containing less protein, zinc and ironRising levels of carbon dioxide could make crops less nutritious and damage the health of hundreds of millions of people, research has revealed, with those living in some of the world’s poorest regions likely to be hardest hit.Previous research has shown that many food crops become less nutritious when grown under the CO levels expected by 2050, with reductions of protein, iron and zinc estimated at 3–17%.

The Consolations of Physics by Tim Radford – review
This stellar ‘love letter to physics’ looks at the wonders of the universe – and asks if they can make you a happier personThe space probe Voyager 1 was launched on 5 September 1977. Its identical twin, Voyager 2, had a 16-day head start on their grand tour of the outer planets. Each had a computing system with about one-millionth of the capacity and capability of a modern smartphone. The Voyager missions were designed to take advantage of a planetary conjunction that happens once every 175 years when Jupiter, Saturn, Uranus and Neptune are on the same side of the sun. A spacecraft launched at the right time could visit all of them in turn, using the gravity of each planet as a slingshot to make it to the next.Travelling at a million miles a day, the duo completed the grand tour in 1989. Voyager 1 became the first human-made object to leave the solar system and enter interstellar space in August 2012 and is heading towards a star called AC+79 3888. Some 17.6 light years from Earth, Voyager 1 should swing past it in about 40,000 years. Continue reading...

Weight-loss pill hailed as 'holy grail' in fight against obesity
US study of 12,000 people shows drug lorcaserin does not increase risk of serious heart problemsA weight-loss pill has been hailed as a potential “holy grail” in the fight against obesity after a major study showed it did not increase the risk of serious heart problems.Researchers say lorcaserin is the first weight-loss drug to be deemed safe for heart health with long-term use. Taken twice a day, the drug is an appetite suppressant which works by stimulating brain chemicals to induce a feeling of fullness. Continue reading...
Starwatch: the Swan soars across the midnight sky
The constellation Cygnus rises in the east this week and is high in the sky by the middle of the nightThis week look out for the glorious constellation Cygnus, the Swan. It is one of the finest constellations that the northern hemisphere has to offer. It rises in the east as the night draws in, and by midnight is soaring high across the sky. Cygnus is shaped like a cross. Its great neck stretches out towards the star Albireo and back towards the tail star: Deneb (which is Arabic for tail). The wings of the swan are longer, and stretch out along a line of fainter stars. Although it cannot be seen by eye, roughly halfway between Albireo and Deneb lies Cygnus X-1, the first black hole to be identified by astronomers. The body and neck of Cygnus lie right along the Milky Way. This misty band of light can be seen from rural locations and is the combined light from the millions of stars that make up our Galaxy. In 1612, Italian astronomer Galileo Galilei described raising his telescope to the Milky Way and seeing it was composed of myriad faint stars. Deneb forms the Summer Triangle, with the bright stars Vega in Lyra and Altair in Aquila. Continue reading...
Roman coins found in Yorkshire revealed after years of secrecy
Detectorists who found silver treasure led archaeologists to high-status site in 2015One of the earliest Roman settlements ever to be discovered in the Yorkshire region has been unearthed by a group of crowdfunded archaeologists.The exact location of the high-status settlement has been kept a secret to protect it from night hawkers (illegal metal-detectorists) and looters, but archaeologists have described it as astounding.

Six to eight hours of sleep best for the heart, says study
Research shows sleep deprivation or excessive hours in bed increase risk of coronary artery disease or strokeSix to eight hours of sleep a night is most beneficial for the heart, while more or less than that could increase the risk of coronary artery disease or a stroke, researchers have suggested.The study, presented at the European Society of Cardiology Congress in Munich, indicates sleep deprivation and excessive hours in bed should be avoided for optimum heart health.

Natural History Museum evolves into theatre to stage Darwin puppet show
Australian writer persuaded museum to convert gallery for run of acclaimed productionAn Australian writer has persuaded London’s Natural History Museum to turn one of its galleries into a theatre to stage his acclaimed puppet show for grownups about the early adventures of Charles Darwin.Following a sellout run in Brisbane, where the show was commissioned, David Morton’s The Wider Earth went on to play at the Sydney Opera House. Now it will be performed in the London museum’s Jerwood Gallery, not far from its Darwin centre, where many of the original specimens brought back by the naturalist are on display.

How walking – and then a pilgrimage – lifted Guy Stagg’s depression
A 60-mile trek brought deep calm. So the author headed for Jerusalem, 5,500 kms awayIn the summer of 2012, on a whim and with no experience of long-distance walking, Guy Stagg decided to trek the 60 or so miles from his home in London to Canterbury. Three years out of university, where he had battled against depression and alcoholism, he’d recently sought medical help to overcome his problems, and wondered whether walking might be beneficial.Canterbury appealed to him, for its role “at the beginning of English literature” – he had been an English student at Cambridge. He set off having done virtually no planning, and arrived in Chaucer’s city two days later. He had walked under baking sun and driving rain with little protection, his heels bruised and his socks clotted with the blood from burst blisters. Continue reading...
Believe in change – for the better | Observer letters
We must exploit the power of positive thinking if we are to curb the effects of dangerous movements in our climateIn 1982, when I was having a bit of an existential crisis while campaigning for nuclear disarmament and heavily pregnant, my father-in-law related the story of a neighbour who’d shot dead his wife, children and himself during the Cuba crisis because he couldn’t face the prospect of inevitable nuclear war. “He could have been enjoying his grandchildren now.”Climate change (It’s the end of the Earth as we know it, Comment) appears to momentous, and not withstanding the depressing (and logical) thoughts that it’s too late, too complex, too difficult and so forth, I still reckon it’s a good strategy to act as if changes in human behaviour, individual and collective, on any scale – massive and radical would be good options – might make a difference. A growing body of scientific researchers, journalists, activists, politicians, ethical lifestylers and eco-warriors keeps going “despite”. Continue reading...
Buildings made from fungi? Meet London’s pop-up bio-lab innovators
A shipping container complex in a Shepherd’s Bush market is the unlikely home to a community of startup research projectsIf there’s one place you wouldn’t expect a new biotech research lab to be built, it’s slap bang in the middle of a busy London market.Yet navigate through stalls selling fish, fabric and phone cases in west London’s Shepherd’s Bush market and you’ll find a brightly painted courtyard and a small A4 sign that reads: “THIS AREA MAY LOOK EXCITING, BUT IT’S REALLY NOT, SO PLEASE DON’T GO THROUGH! THANKS.” Continue reading...
Skim reading is the new normal. The effect on society is profound | Maryanne Wolf

Experience: I can't picture things in my mind
I have a condition called aphantasia where I can’t visualise things. When I try to picture my daughter when she’s not there, I see nothingI was seven when, in hindsight, I first questioned my imagination. I remember watching the first Harry Potter film and my friend, who was a huge fan, was complaining that the characters weren’t how she imagined them to be. I couldn’t understand what she meant because, in my mind, they had never been images at all, just concepts. When I shut my eyes, I see nothing. It is black. I have no visual imagination.I thought everyone’s minds worked this way until about two years ago, when I stumbled across a blog post about aphantasia; a condition where you lack a functioning mind’s eye. I was 23, and it blew my mind to learn that others could visualise things. I’d never known any different but it was clear I had aphantasia, too, and a lot of things started to make more sense.

Spacewatch: Aeolus to track the winds
A satellite launched by rocket from French Guiana this week will be the first to directly measure winds around the globeThe European Space Agency launched the Aeolus mission at 10.20pm BST (18:20 local time) on 22 August from its spaceport in Kourou, French Guiana. It took 55 minutes for the Vega rocket to place the spacecraft into a 320km (198-mile) high orbit. Contact was then established through the Troll ground station in Queen Maud Land, Antarctica at 11.30pm.The mission carries revolutionary ultraviolet laser technology to measure the winds around the globe. It will be the first satellite to provide wind profiles that begin at the surface of the Earth and extend upwards to 30km. When fully operation the satellite will supply 64,000 profiles a day.

Russian trolls 'spreading discord' over vaccine safety online
Study discovered several accounts, now known to belong to the same Russian trolls who interfered in the US election, tweeting about vaccinesBots and Russian trolls spread misinformation about vaccines on Twitter to sow division and distribute malicious content before and during the American presidential election, according to a new study.Scientists at George Washington University, in Washington DC, made the discovery while trying to improve social media communications for public health workers, researchers said. Instead, they found trolls and bots skewing online debate and upending consensus about vaccine safety. Continue reading...

Plant roots evolved at least twice, and step by step | Susannah Lydon
The discover of a unique rooting anatomy from 407m years ago supports theory roots evolved at least twice, and step by stepMost of us do not spend much time contemplating plant roots. Not only do they suffer from the wider issue of plant blindness, but they are also the bit of the plant that is not visible. In terms of getting people excited about plant science, it’s a tough gig. This is a shame, because plant roots are critical to all of our lives: no roots means no food. Roots provide anchorage, and allow plants to gain water and nutrients from the soil. They also form a key symbiotic relationship with mycorrhizal fungi, which provide minerals from the soil in return for a steady supply of carbs from the plant.In the modern world, we can easily divide plants into the ones that have roots and the ones that don’t. The flowering plants (angiosperms) and the other vascular plant groups (conifers and other seed plants, ferns, horsetails and clubmosses) all have a recognisable root, defined by having a meristem of rapidly-dividing, undifferentiated cells, and by having a root cap, which protects the apex of the growing root and which is where the plant perceives gravity.

Open science is now the only way forward for psychology
Next week the Guardian will be closing the Science Blog Network. We take a final look at the journey psychology has made toward becoming a robust and mature scienceWhen we launched Head Quarters five years ago, psychology was in a pretty dark place. The field was still reeling from the impact of the Diederik Stapel fraud case – the largest perpetrated in psychology and one of the greatest ever uncovered in science. At the same time, a cascade of failures to replicate major findings was just beginning, and as if to add insult to injury, one of psychology’s most prestigious journals published a study claiming to confirm, of all things, the existence of psychic powers.Psychologists were faced with one inescapable conclusion: that the research culture in the field was fundamentally flawed and needed urgent attention. Five years later, the field has taken some big steps forward toward righting the ship. Let’s take a look at some of those improvements. Continue reading...

Survival of the slackest: now that’s what I call an evolved theory | Larry Ryan
Fellow captains of indolence, rejoice. A study of molluscs holds out hope for those of us of the laid-back persuasionBack when I was at university in Dublin, I once gave blood at a nearby donation clinic. They gave you a free sandwich beforehand to prevent blood-depleted fainting so it was a good deal in straitened, student times (I had the chicken). Post-lunch, a nurse hooked up my arm to get the blood; after a while a doctor came over to observe, and asked how it was going. “There’s not much coming out,” the nurse complained. “His blood is pumping too slow.”I can’t claim there is a direct medical correlation between this incident and a general sense of idleness and languor that I often feel, but it gives me comfort. Even when most of the world persists with the silly idea that sloth is a sin, there are plenty of us out there who are content with being lazy, laid-back or whatever ... It is with mild joy, then, that I receive recent news that researchers are hailing “the survival of the sluggish”. Analysing 300 forms of mollusc that lived and died in the Atlantic over a 5m-year period, scientists found the creatures that burned the most energy daily were more likely to die out than those that took it easy. “The lower the metabolic rate, the more likely the species you belong to will survive,” said Bruce Lieberman, the University of Kansas professor who led the study.

Michael Gove’s puppy-farm ban shows he gets the politics of pets | Anne Perkins
Is the environment secretary pandering to sentimentality – or on to the fact that our understanding of animals is changing?Ever since Michael Gove inadvertently found himself on the wrong side of a row over animal sentience at the end of last year, he has been all over animal welfare with the uninhibited enthusiasm of a python preparing its dinner. His latest move is a bid to stamp out the hideous cruelty of puppy farming by introducing a ban on the sale of kittens and puppies in pet shops. In future, would-be pet owners will have to go direct to the breeder or (so much better) to a pet-homing charity.The Mirror, which has run an energetic campaign calling for the ban, is thrilled. Earlier this year, Battersea Dogs Home was equally chuffed when the environment secretary promised tougher sentences for animal cruelty, and the Express has only just got its breath back from cheering Gove on after he posed with Finn, the police dog who nearly died protecting its handler, and pledged tougher sanctions against anyone who attacked service dogs or horses. True, he has been persuaded that a total ban on electric collars for dogs and cats, used for restraint and training, might have the unintended consequence of leading to more pets dying on the road, but the direction of travel is unmistakable: in a world polarised by Brexit, pets can be the new politics.

Lack of sleep makes people pile on the pounds
Disrupted sleep alters metabolism and boosts body’s ability to store fat, data showsLack of sleep has long been linked to obesity, but a new study suggests late night snacking may not be the primary culprit. The latest findings provide the most compelling evidence to date that disrupted sleep alters the metabolism and boosts the body’s ability to store fat.The findings add to mounting scientific evidence on how disrupted sleep influences the usual rhythms of the body clock, raising the risk of a wide range of health problems from heart disease to diabetes.

Offspring of Neanderthal and Denisovan identified for first time
Discovery suggests that distinct ancient human species may have mingled and interbred happilyA small piece of bone found in a cave in Siberia has been identified as the remnant of a child whose mother was a Neanderthal and father was a Denisovan, a mysterious human ancestor that lived in the region.Researchers made the discovery when they examined DNA extracted from the bone and found that it contained chromosomes from a Neanderthal female and a Denisovan male. It is the first time that the offspring of such a coupling has been identified. Continue reading...

Lost Worlds wrapping up: dead birds, island hopping and the value of museum collections
With the Science Blog Network closing, Hanneke Meijer reflects on her contributions to the Guardian’s Lost Worlds RevisitedDespite all the splendid fossils we have covered here on Lost Worlds Revisited, nothing lasts forever (apart from the cold November rain here in Norway). In my time on here, I have covered a range of topics, from Darwin’s finches, the peculiar nature of island faunas, and penguin feet, to chickens, the evolution of feathers, and Club Med. Although they may seem rather arbitrary at first, they reflect my main interests in island paleobiogeography and avian evolution.Lost Worlds Revisited allowed me to rave on about research and fossils I felt the world needed to hear more about. For instance, dodos were not dumb sitting ducks, but exquisitely well adapted to their environment (a hill I’m willing to die on), Komodo dragons may be dwarfs instead of giants, and precious baby birds in amber. But it also gave me the opportunity to delve into topics and ideas that I felt I needed to learn more about, such as the evolution of feathers, how bird eggs get their colours, and even frogs.

A dying patient asks could I have done more to save her – she is right to need an answer | Ranjana Srivastava
To doubt one’s every move as a doctor would compromise patient care but to never question it at all would be follyAfter many years of a firm and faithful association, the predictable has occurred. Her cancer has progressed, and she has gone from being a robust mother and devoted wife to a mere shadow of her former self, confined to her bed, in turn lamenting over and bewildered by how it has come to this. In hospital, my hand reaches out to her in sympathy and she clutches it as tears stream down her face. “Why, why, why?” The conclusions of scientific research whisper in my ears, “because it’s bad biology” but the consolation falls flat amid the visible devastation of illness. Our journey together has been difficult with the wins competing with the setbacks.Related: To treat or not to treat: find out what really matters to the patient | Ranjana Srivastava Continue reading...
Forget 'survival of the fittest' – the laziest will inherit the earth
Species which use the most energy in their daily lives die out quicker than less energetic animals, say evolutionary biologistsIt is the perfect comeback for those who are admonished for not pulling their weight. Never mind that work is piling up, being lazy is a winning evolutionary strategy that postpones the extinction of the species.That, at least, is one interpretation. Researchers who studied nearly 300 forms of mollusc that lived and died in the Atlantic over the past five million years found that a high metabolism predicted which species had gone the way of the dodo.

Worrying about robots stealing our jobs? How silly | Simon Jenkins
The digital age will free us up not only for leisure activities but also to take on caring roles that can only be filled by humansSo we are doomed. Robots will steal our jobs. Algorithms will capture our children. Artificial intelligence will corrupt our free will. We are to be slaves to machines.The Bank of England economist Andy Haldane warns today that “large swathes” of current labour will disappear as AI takes over. For a man who lives and breathes statistics, large swathes is a poor percentage. These jeremiads attended the invention of computers, combine harvesters, spinning jennies and probably iron-age axes. But no one gets on the Today programme for predicting that AI might be good news. Continue reading...
Summer weather is getting 'stuck' due to Arctic warming
Rising arctic temperatures mean we face a future of ‘extreme extremes’ where sunny days become heatwaves and rain becomes floods, study saysSummer weather patterns are increasingly likely to stall in Europe, North America and parts of Asia, according to a new climate study that explains why Arctic warming is making heatwaves elsewhere more persistent and dangerous.Rising temperatures in the Arctic have slowed the circulation of the jet stream and other giant planetary winds, says the paper, which means high and low pressure fronts are getting stuck and weather is less able to moderate itself.

Turnbull just showed what happens when 'ideology and idiocy take charge of energy policy' | Erwin Jackson
The PM had seemed to recognise that you can’t have an energy policy without a plan to cut emissions. No longerA note to our prime minister: you can’t have an energy policy that assumes that climate change does not exist. By dumping the commitment to take emissions targets to the federal parliament the PM is signalling climate change is not real. This leaves the rest of us paying the price for another political capitulation on cleaning up our power sector.Some parts of the government don’t believe in climate change. Their ideological ties to the coal-based power systems built 40 to 50 years ago has scuttled every attempt to develop credible climate change energy policy over the past 10 years, leaving us where we are now.

Modern myths about cancer – from ‘chemicals’ in food to wifi
The idea that lifestyle changes have made the disease more common is a gross exaggeration – but increasingly prevalent. We separate fact from fictionCancer is not up there with the most likely explanations for what caused the mass extinction 66m years ago of the T rex and the triceratops. That said, at least one species of dinosaur suffered from blood-vessel tumours – and a 1.7m-year-old toe with bone cancer was discovered in 2016 at a South African world heritage site.Cancer may have been more common in ancient times than we will ever know, because fossilisation will have obliterated most evidence of the disease. However, misinterpretations of some small studies and claims by self-styled wellness gurus that cancer is “a man-made disease” have fed the belief that cancer is modern. While that does not mean anyone concerned about cancer should visit their local natural history museum for information, thinking of cancer as a result of modern life causes unnecessary fear. Here are some modern myths about cancer. Continue reading...
Politicians must set aside blinkered ideologies in the climate end-game | David Spratt and Ian Dunlop
The rapidly disintegrating ‘agreement’ to the Neg yet again sees the Coalition refusing to face up to the threat of climate changeHumanity has a big decision to make very soon about its future on warming planet, but the federal Coalition is still in denial that human-induced climate change even exists, let alone that the climate end-game is upon us.The national energy guarantee (Neg) is the latest manifestation of that denial. A third-rate complex, over-engineered policy that will most likely fail to contribute to meeting all three of its main objectives, namely increased reliability of electricity supply, lower energy prices and a long way third, reducing carbon emissions. A compromise upon compromise designed to placate the scientifically and economically-illiterate Coalition rightwing, which ignores the first priority of any government, to ensure the security of the people. For climate change is now the greatest threat to that security. Continue reading...

Starwatch: Sagittarius plays host to Saturn and the moon
Find both Saturn and the moon above the “teapot”, the most familiar asterism in the the constellation of the ArcherThis Tuesday, keep an eye open for a nice conjunction of Saturn and the moon. They will be visible in the southern sky as twilight turns into night. Saturn was at its closest approach to the earth in June but remains a bright yellowish light in the sky.
