The former Nasa scientist criticizes the talks, intended to reach a new global deal on cutting carbon emissions beyond 2020, as ‘no action, just promises’Mere mention of the Paris climate talks is enough to make James Hansen grumpy. The former Nasa scientist, considered the father of global awareness of climate change, is a soft-spoken, almost diffident Iowan. But when he talks about the gathering of nearly 200 nations, his demeanor changes.

New research shows that unhappy and stressed people are no more likely to succumb to ill-health or premature death than their cheerier counterpartsThe happiness industry – now contracted to consult with everyone from corporate America to the US military – thinks your well-being is a matter of individual effort and personal responsibility. This is the American dream applied to the soul: the faith that if we put in enough emotional elbow grease, if we read enough self-help books and practice mindfulness and think positive and meditate and keep a gratitude journal, then we can pull ourselves up by our bootstraps from misery to joy.A thousand inspirational virtual photo-cards declare that ‘happiness is a choice.’ Even the dictionary agrees. Although the word happiness originally came from the Middle English word “hap”, meaning chance or good luck (think ‘happenstance’ or ‘perhaps’), any idea that our own wellbeing may be outside of our direct control has been firmly squashed. Merriam Webster’s online dictionary now declares that the old definition of the word happiness as “good fortune” has become obsolete.

We search for science fact in the world’s most popular science fictionObi-Wan Kenobi called it an “elegant weapon for a more civilised age”, but it’s more like a humming glowstick that’s also lethal. “Lightsabers appear to work like superheated swords, able to slice through metal, human or alien tissue,” says Dr Iain Beardsell FRCEM, a consultant in emergency medicine. “So any victim would probably be taken to the nearest UK major trauma centre, possibly by air ambulance.” Even a glancing blow would likely cause so much trauma, the doctor-paramedic team would place the patient into a drug-induced coma using a “rapid sequence induction of anaesthesia and intubation”. But it’s not all bad news. “There is a chance a patient with these injuries may well survive,” says Beardsell. “One advantage of being struck by a lightsaber rather than a conventional blade might be the immediate cauterisation of the wound from the associated heat, stopping bleeding instantly.” So if a Sith Lord scythed your hand off, it could be reattached? “Possibly,” he says. “Hours of plastic surgery would be required, but the clean edges would actually aid the procedure. It would preserve the limb beautifully.” GV Continue reading...

Non-profit research company OpenAI to seek ‘a good outcome for all over its own self-interest’, say Tesla boss and others donating a combined $1bnSome of the most prominent executives in the technology industry including the Tesla and SpaceX boss Elon Musk are backing a non-profit artificial intelligence research company with funding of $1bn.

Duration of day has lengthened by a millisecond over the past 100 years as water from shrinking glaciers slows Earth’s rotation and shifts position of polesThe impact of climate change may appear to be overwhelmingly negative but there is a bright spot for those who struggle to find enough time in the day: melting glaciers are causing the rotation of the Earth to slow thereby lengthening our days, new research has found.Harvard University researchers have provided an answer to a long-held conundrum over how shrinking glaciers are affecting the rotation and axis of the Earth, calculating that the duration of a day has lengthened by a millisecond over the past 100 years.

Archaeologists claim carbon dating of ancient weapons found in Kessel proves Roman emperor led massacre of Germanic tribes on Dutch soilArchaeologists claim to have proved that Julius Caesar set foot on what is now Dutch soil, destroying two Germanic tribes in a battle that left about 150,000 people dead.The tribes were massacred in the fighting with the Roman emperor in 55BC, on a battle site now in Kessel, in the southern province of Brabant.

Anticipation builds for COP21 to deliver a groundbreaking deal as experts welcome draft statement to keep warming to well below 2CThere’s a cafe next door to the thronging media centre at the UN global climate talks in Paris where the constant clang of the door to the chill air outside can barely be heard above the buzz.Veteran climate scientist and biologist Prof Lesley Hughes has taken a seat with me close by and is struggling to hear herself think.

The Force Awakens is in UK cinemas next week, which should give you enough time to brush up on your physics and make yourself some appropriate kit ...This piece was originally published on The Conversation.As even casual Star Wars fans will know, lightsabers are probably the coolest weapon ever to make an appearance on the big screen. Lightsaber fights are so elegant that they are almost hypnotic and, even though not all of us might have a strong enough flow of Force running through our veins, a lightsaber in the right hand is by far the deadliest weapon to be found in the universe.

The former helicopter test pilot is used to danger, but on Tuesday the British astronaut will face new challenges aboard the Soyuz rocket, bound for the ISSThe area cleared around the Soyuz rocket at Baikonur Cosmodrome in Kazakhstan extends for more than a mile before reaching the observation area where family and colleagues gather on launch day. To watch from afar has several advantages. It is easier on the neck, for one. The roar of the 26 million horsepower engines is bearable that far out, too. The main reason, though, is more sobering. At such distance, the crowd should be safe if the Soyuz, a machine that burns 270 tonnes of fuel and oxygen in nine minutes, explodes.On Tuesday, Tim Peake, the first Briton admitted to the European astronaut corps, will ride a coach into the heart of Baikonur’s exclusion zone. After a short stop to urinate on the coach’s rear right wheel, a tradition embraced since Yuri Gagarin did the same more than 50 years ago, Peake will take his seat in the capsule on top of the rocket. At 11.03am UK time, the engines are due to light up, blasting Peake and his two crewmates into the sky. He is not expected back until June.

Douglas Walker, who has died aged 87, was the longest-serving managing director of the agricultural and grounds care equipment company John Deere.Doug, as he was known, was a key figure in the company’s establishment and growth in the UK and Ireland after it started trading from headquarters at Langar, near Nottingham, in January 1966. In the 25 years under his leadership it developed into a strong, well-known organisation. Continue reading...

Coins and other items buried in the late 870s and found by hobby metal detectorist in farmer’s field in Oxfordshire may be worth a small fortuneA hoard of Viking silver that casts new light on Alfred the Great and the one-time ally he virtually obliterated from history has been found by a metal detectorist in a field in Oxfordshire.The hoard, described when it arrived at the British Museum as “a greasy haggis with bits of treasure sticking out at the corners”, was buried in the late 870s, the period in which the hit television series Last Kingdom is set. It may have been the hastily concealed wealth of a Viking conscious of imminent regime change after the defeat of the invaders by Alfred the Great at the battle of Edington in 878.

Jenny Rohn: Despite years of effort, women remain under-represented in science. But are there really any neat solutions?Another week, and another attempt to engage girls in the sciences being widely ridiculed on Twitter. This time it was IBM, whose hastily withdrawn campaign joins the ranks of other criticised efforts, including the European Commission’s “Science: It’s A Girl Thing” video, and EDF Energy’s “Pretty Curious” initiative.One can’t help feeling a bit sorry for IBM and other corporations whose well-meaning efforts fall flat. I personally found nothing offensive about the IBM video, which invited aspiring female engineers to subvert a so-called “girly” household object into something more interesting (examples included a hot air-driven clock). In fact, the video explicitly challenged the stereotype that women are only interested in body image. Unfortunately, the territory of “pinkification” is so sensitive and fraught that it seems to be off-limits as a hook – even one that subverts the stereotypes instead of feeding them.

With cities and regions behind more than 70% of climate change reduction measures, it is crucial they’re included as partners in the Paris agreementCompared with previous UN conferences, there seems to be a far greater sense of optimism at the Paris climate talks. Before the start of the negotiations more than 146 countries, representing 86% of global emissions, submitted their plans to cut them. Yet this was deemed not enough: it would have only, according to the UNFCCC , limit temperature rises to 2.7C by 2100 – not the 2C scientists consider to be the maximum the world can tolerate.Related: World will pass crucial 2C global warming limit, experts warn Continue reading...

A professor from Cornell University College of Veterinary Medicine, Alexander J. Travis, explains the conservation benefits behind the first litter of puppies born through IVF. The healthy delivery of the dogs by caesarean section on 10 July marks a success that has eluded scientists since efforts began in the mid-1970s. The procedure could transform attempts to save endangered dog species, and potentially help prevent the genetic disorders that afflict so many breeds Continue reading...

Nineteen embryos, seven pregnancies, one female beagle ... scientists say procedure could save endangered species and prevent genetic disordersFrom the paint on their toes and the tips of their tails, the puppies stand out as unusual. But the litter of seven will go down in history for more than the colours that tell them apart. Now five months old and doing well, the dogs are the first to be born through IVF.The healthy delivery of the dogs by caesarean section on 10 July marks a success that has eluded scientists for 40 years since efforts began in the mid-1970s. The procedure could transform attempts to save endangered dog species, and potentially help prevent the genetic disorders that afflict so many breeds.

Fresh images from Nasa’s probe reveal sparkly patches on dwarf planet likely to be water vapour emanating from subsurface iceWhen Nasa’s Dawn spacecraft reached the largest object in the asteroid belt earlier this year, mission scientists were baffled to find that the alien terrain gleamed with giant bright spots.The glinting patches on the surface of Ceres sparked an intense debate among astronomers who could not work out if the shiny material was frozen water, reflective salt deposits, or even geysers blasting water vapour into space.

The author’s radio quest to unlock the scientific genius of James Clerk Maxwell ends in frustration, but the journey is revelatoryThere’s a potent antidote to the “Isn’t this amazing?” school of science communication and it’s called Will Self. In Self Drives: Maxwell’s Equations, which was broadcast recently on BBC Radio 4, the curious curmudgeon takes science to task once again as he goes in search of the mathematical and physical genius behind James Clerk Maxwell. In the 19th century, Maxwell’s electromagnetic theory unified electricity, magnetism and light in four compact, if redoubtable, equations, which celebrate their 150th anniversary this year.Over five short episodes, Self’s querulous quest takes him from Maxwell’s birthplace in Edinburgh to his family home in Glenlair, to the radio telescope at Jodrell Bank and the Diamond synchrotron near Oxford, and finally to Cambridge, where Maxwell studied mathematics in his youth and returned in his latter years as one of the nation’s most accomplished scientists to head the university’s Cavendish physics laboratory. Accompanying Self along the way is Akram Khan, the same physics professor who joined the errant writer on his earlier orbit of the Large Hadron Collider at CERN. I would have dubbed Khan Sancho Panza to Self’s Don Quixote but for this particular expedition the characters are reversed. It is Khan who wishes to see the poetry of science, while Self is happier to be grounded in prosaic and flawed reality. At CERN he refused truculently to worship in the cathedral of particle physics, stymied in equal measure by the difficulty of the subject matter and the boosterism of its scientific proponents. Here again the journey is mostly one of disappointment and frustration. Continue reading...

SSRIs may not be for everyone, but when anxiety dominated my life, they brought me into a world of reliefI think of it as the warm chord. I was sitting in the front room, alone. My parents had gone to bed, but I wanted to listen to a CD I’d bought. I turned the light out, to immerse myself. That in itself was strange. When you’re anxious, immersing yourself in a feeling seems like a bad idea – your skin is so thin anything might penetrate it and overwhelm you, a song or a smell or a mood. But I took the risk, and instead of fear – the heartbeat stoking, paralysing fear I’d experienced for much of the past year – there was something else. Fear had left a space, one I was invited to explore. It said: you can come out now.But alongside that, there was a positive presence, a low thrum of safety. A warm chord. Nothing to do with the music; it was more elemental than that. I sat and the world turned, but without the familiar promise of danger. A stillness settled over everything. I no longer had to hold all of existence in my hands, as if super-human vigilance could protect me from harm. Continue reading...

It’s so easy to scoff at pseudo-profound sayings, but in my dark times I have found them comfortingIf you’re offended by swearing, apologies, because I’m about to use the word bullshit quite a lot. It’s not my fault. It’s because researchers who recently published a paper about the intelligence of people who believe in the wisdom of inspirational quotes were awfully fond of the word bullshit. It appears in the title, On the Reception and Detection of Pseudo-profound Bullshit; it’s there five times in the abstract alone; and the first keyword is – well, you can probably guess.The researchers were extremely keen to know whether certain people were more likely to believe in pseudo-profound statements, and whether that had anything to do with intelligence. You know the kind of thing: phrases such as “You can’t start on the next chapter of your life if you keep rereading the last one” or “If opportunity doesn’t knock, build a door.” Continue reading...

Sting operation uncovers two prominent climate sceptics available for hire by the hour to write reports on the benefits of rising CO2 levels and coalAn undercover sting by Greenpeace has revealed that two prominent climate sceptics were available for hire by the hour to write reports casting doubt on the dangers posed by global warming.Posing as consultants to fossil fuel companies, Greenpeace approached professors at leading US universities to commission reports touting the benefits of rising carbon dioxide levels and the benefits of coal. The views of both academics are well outside mainstream climate science. Continue reading...

Last Wednesday BBC2 Scotland gave us an excellent hour-long programme on James Clerk Maxwell: The Man Who Changed the World – recognised as the greatest scientist between Newton and Einstein. When Einstein was asked if he stood on the shoulders of Newton, he replied “No, on the shoulders of Maxwell”; he gave Maxwell’s photo pride of place on his study wall (100 years on, is this Einstein’s greatest gift to humanity?, 7 December). BBC2 viewers outside Scotland were treated to the Tottenham MP’s advice surgery. Whether or not the BBC shows Maxwell more widely in future, such programmes surely justify simultaneous transmission throughout Britain. Scottish ignorance of our home-grown genius is sad enough; it’s probably even worse elsewhere.

Tests show compound, similar to that found in energy drinks, clears amyloid beta plaques, which build up in the brain in early stages of Alzheimer’sScientists have discovered a chemical that destroys toxic plaques which build up in the brain in the early stages of Alzheimer’s disease.Preliminary tests found that when added to drinking water, the compound cleared amyloid beta plaques from the brains of mice with Alzheimer’s-like symptoms, and restored their cognitive function to normal.

Charisma must be stopped, if any quick-witted person with nice teeth has it. No new kid on the block should be able to Farage us all with a devastating bon motFinally, researchers have figured out the deep truth of what charisma is, and it’s basically “just being quick”. Yeah, George Clooney: I’m on to you, buddy. According to a University of Queensland study, the ability to think and act quickly is a key column around which the most intangible of personality traits is built. They backed up their findings with a do-it-as-quick-as-you-can general knowledge quiz, and found that those who completed it quickly were viewed as more charismatic by their friends. The study also looked at the most likeable musicians, leaders and celebrities. “When we looked at charismatic leaders, musicians and other public figures, one thing that stood out is that they are quick on their feet,” research leader William von Hippel said. “Our findings show that social intelligence is more than just knowing the right thing to do. Social intelligence also requires an ability to execute, and the quickness of our mind is an important component of that ability.”Related: If bacon-sandwich charisma defines political leadership, only Nigel Farage wins | Stefan Stern Continue reading...

It may have been ill-conceived, but it doesn’t take a rocket scientist to know that IBM’s ‘hack a hairdryer’ campaign wasn’t actually aimed at women already doing great thingsIBM promoted the video on Friday. The internet got vexed on Saturday. Things got even more heated on Sunday. IBM apologised profusely on Monday. Someone probably got sacked on Tuesday. No, this isn’t a Craig David song gone horribly wrong. It’s the timeline of an IBM marketing initiative gone horribly wrong.The tech company has just axed a campaign that asked young women to “hack a hairdryer”. The point of this “hacking”, by the way, was to encourage more women to pursue Stem (science, technology, engineering and mathematics) careers – not to increase the incidences of electrocution in the bathtub.

Going feet first into evolutionary theory, the race to crack the genetic code and a memorable journey around the coast of Britain

After two ecstasy deaths at the Stereosonic festivals, it’s imperative that we get our facts straight about the drug, or more young people will die, say two leading experts on drug use and policyThe recent tragic deaths of two young people after taking ecstasy at the Stereosonic music events in Sydney and Adelaide prompted much media comment. Unfortunately, much of it was misinformed.Unless we can agree on the basic issues and realistic options, sadly more young people will continue to die. Ecstasy is very different from and a much less dangerous drug than “ice”, the subject of prime minister Malcolm Turnbull’s announcement of a National Ice Action Plan on Sunday. Continue reading...

Review on antimicrobial resistance warns that antibiotic use on animals outweighs that on humans in many countries, posing great health riskThe use of antibiotics in agriculture is fuelling drug resistance and must be cut back or even banned where they are important for humans, a report commissioned by David Cameron has warned.The Review on Antimicrobial Resistance said global use of antimicrobials in food production at least matched that by humans, extending even to the widespread application in some areas of “last resort” antibiotics for humans – which cannot be replaced when ineffective – to animals.

The notion that scientists are easy prey to jihadism is scurrilous because of the false assertion that scientific education is uncritical (Paul Vallely, Opinion, 4 December). Putting aside the issue of whether 18 British Muslims make up a reliable sample, it can be hypothesised that it is more likely that jihadism might be a reaction against the critical scientific approach that denies the veracity of many of the events in the religious texts. What is equally disturbing is that Martin Rose of the British Council fails to understand that science is the very essence of British culture – a culture that has produced, or encouraged, scientists and philosophers of science such as Roger Bacon, Francis Bacon, Newton, Hooke, Boyle, Wallace, Darwin, Rutherford, Crick, Popper and Sanger (to name just a few). Our success in this area comes about because British scientists are critical and question authority.

The singer is planning an experiment at Monkey World in Dorset to see if chimps can use videoconferencing to chat to each other – or even to usWhat if the internet that humans currently use could be extended to other species?This is the kind of idea that the musician Peter Gabriel has long been interested in. As part of the Interspecies Internet project, which he has been working on with pioneers such as Vint Cerf, one of the architects of the internet, and academics such as Neil Gershenfeld, professor at the Massachusetts Institute of Technology (MIT), Gabriel is planning to run an experiment at Monkey World, the Dorset-based chimp rescue centre.

Palaeontologists re-examine a 200-million-year-old fossil from Greenland, reigniting debate about the origins of mammalsHow old are you? What if, when someone asked you this question, you answered with the age of all humans? 2.3 million years, you would say. What about all primates? Around 80 million years old. If you wanted to answer for the whole of mammal-kind, you’d find the answer depends who you ask.

From Republican presidential candidates to hard-core Corbyn supporters, we’re used to hearing extreme views from all over the political spectrum and beyond. Why?As a British person with liberal leanings, the ongoing coverage of the US Republican race to select a presidential candidate is often baffling. Much of this is due to Donald Trump, of course. Donald Trump, the ungodly offspring of a retired golfer and a beligerent tangerine. Donald Trump, a man who once heard the word “unspeakable” and thought “challenge accepted!” Just when you think he couldn’t possibly be more openly offensive towards large groups of people, he reliably proves you wrong a few days later.Despite this, it seems a large number of people still think he’s the best person to be President, where he can bring about nuclear Armageddon by openly mocking Vladimir Putin’s height at some international summit.

The detection of gravitational waves will open up a new spectrum of the universe – finally demonstrating a theory presented a century agoHistory may judge 2015 as the year when mankind opened up a completely new window on the universe, exactly a century after Albert Einstein laid the scientific foundations for it. The excitement concerns the possibility of detecting one of nature’s most elusive phenomena – gravitational waves – which could pave the way for a much better understanding of black holes, neutron stars and other violent astronomical systems.Several new projects have been launched in the past few months to make gravitational waves the Next Big Thing in astronomy. Rumours have it that one of these – the US’s Advanced Laser Interferometer Gravitational-Wave Observatory (Advanced Ligo) – already “detected something” in September, but the scientists involved remain tight-lipped. Time will tell. Continue reading...
