Does watching Fast and Furious turn drivers into speed merchants?
A survey has observed a spike in the average speeds of those who had just seen one of the franchise’s films. But it might be best to cover the brakes before leaping to any hasty conclusionsThe next time you get a speeding ticket, it might be worth arguing that the movies are to blame. A research paper by Dr Anupam Jena of Harvard medical school has suggested films in the Fast and Furious franchise may be responsible for drivers hitting the accelerator too hard.Jena unearthed details from 200,000 US speeding tickets that had been posted online, and studied those issued in the week following the release of films in the franchise. The research didn’t find any increase in the number of tickets issued, but did find that the average speed listed on the tickets increased markedly. Continue reading...

Gill Gorell Barnes: ‘Fathers are no less important than mothers’ | David Brindle
When families split, men get left behind emotionally and lose out on bonding with their children to the detriment of both, says the renowned family therapistFrom the age of seven Gill Gorell Barnes found herself mixing with a louche 1950s crowd in a cafe run by her father in London’s Soho. The experience left her entirely non-judgmental, she reflects, teaching her to respect actors, musicians and prostitutes alike as she served them tea and toast and, later, the exotic new offering of frothy coffee. Her father was bisexual and her mother frequently absent, as an editor in the film industry, making her childhood less traditional. Summers were spent with a grandmother in Margate, where she spent long hours alone on the beach. Nothing much she has encountered since in a distinguished career as one of the UK’s leading child and family social workers and therapists has come as a great surprise.Gorell Barnes, now 74, has specialised in fractured and reformed families, learning to see divorce and repartnering from the child’s point of view. In a new book, Staying Attached: Fathers and Children in Troubled Times, she focuses on men and children who live apart, their relations often complicated further by mental health difficulties – an issue largely neglected in family therapy, she argues.

E-cigarettes should be on sale in hospital shops, health body says
More could be done to get people to switch to products that are safer than smoking cigarettes, say Public Health EnglandVaping should be widely encouraged as a way to help people quit smoking, and e-cigarettes should even be offered for sale in hospital shops, the government’s public health body has said.At least 20,000 people a year could be giving up cigarettes thanks to vaping, according to Public Health England’s (PHE) latest review, which said more could be done to get people to switch to products that are far safer than smoking.

Why communication from a ‘locked-in’ child is a miracle we must question
If Jonathan Bryan can communicate we should celebrate, but hard evidence is needed before we change how severely disabled children are cared forThere has been much coverage lately – including in the Times, the Mirror, the Daily Mail, and tonight’s CBBC documentary special – of the story of 11-year-old Jonathan Bryan and his remarkable ability to write poetry, keep a regular blog, and communicate with his parents, in spite of his severe and debilitating cerebral palsy. Now Jonathan – who communicates via a spelling board with the help of a facilitator who carefully watches the movement of his eyes – is campaigning for other severely disabled children to be taken out of special educational needs classes and taught in regular classes, just as he is.
Xanax misuse: doctors warn of 'emerging crisis' as UK sales rise

Could ketamine help treat alcohol dependence?
Current treatments for alcohol dependence often fail. So researchers are investigating more unusual interventionsJanuary 2018 has come to an end and with it the month that people increasingly use to abstain from alcohol. It is still unknown whether Dry January has a lasting effect on drinking behaviours, and people with an alcohol dependency problem should always seek support from their GP before going through detox. Nonetheless, Dry January undoubtedly drives a critical conversation about alcohol use and provides an opportunity for us to reconsider our relationship with alcohol (one of the main goals of the charity Alcohol Concern, who support the challenge).While overall alcohol consumption in the UK is falling, alcohol abuse still represents the fifth biggest risk factor for illness, death and disability across all ages. With current treatments often failing to prevent relapse in the long term, researchers are investigating the possibility of using ketamine combined with psychological therapy to help people stay dry, and not just for January. Despite its often cited use as a recreational drug and “horse-tranquilizer” ketamine is also the most widely used anaesthetic in humans. Administered appropriately in a controlled and safe medical environment, ketamine may also have benefits in the treatment of drug problems. Continue reading...
'Dangerous gaming': is the WHO right to class excessive video game play as a health disorder?
Industry figures question research that ‘pathologises’ compulsive gaming, while scientist involved defends move to address addictionThe World Health Organization (WHO) has included “gaming disorder” in its draft for the next edition of its diagnostic manual, the International Classification of Diseases (ICD-11), which is due for final release this year. The disorder is characterised by behaviours such as impaired control of time spent playing video games and prioritisation of gaming above other activities, in a way that negatively affects other areas of a person’s life such as their education, occupation and relationships.Games industry bodies the US Entertainment Software Association (ESA) and UK Interactive Entertainment (Ukie) have expressed doubts about the classification. “We are very concerned about the inconclusive nature of the research and the evidence that WHO is using to base this potential classification on,” says Ukie’s chief executive, Jo Twist.

Starwatch: distant encounter between the red planet and a red giant
Mars and Antares will be close together in our skies this week, but are separated in space by hundreds of light yearsAll week, the planet Mars will be close to the bright star Antares in the constellation Scorpius. Both will appear to the naked eye as red dots of approximately the same brightness in the pre-dawn sky. Mars gets its colour from the dust on its surface that reflects sunlight. Antares on the other hand is a red giant star, 700 times the diameter of the Sun and vastly further away. Whereas the light from Mars takes just over 13 minutes to cross the space between us, from Antares it takes around 604 years. This means Mars appears as it did just a quarter of an hour ago, whereas the light from Antares began its journey across space in the year 1414. At the end of the week, early risers are in for a special treat. The chart shows the situation at 05:00 GMT on 9 February, when Mars and Antares will be joined low in the southern sky by a waning crescent moon. Continue reading...

So men are dying because they don’t have women’s brains? Show me the evidence
Mortality rates for prostate cancer are rising, but not because of any neurological determinismIt is the crossover moment. For the first time, more men are dying of prostate cancer than women are from breast cancer. Any GP surgery will offer a blood test to check a man’s prostate-specific antigen (PSA) indicating cancer. All men have to do is ask.The trouble is that, as we all know, men are from Mars. They don’t go to GPs, don’t talk about illness and believe in their own invincibility. Men with their compartmentalised brains are inherently greater risk-takers and believe they will beat the odds. In any case, to concede the threat of illness is an acknowledgement of weakness – very unmasculine. Continue reading...
The DNA database that is key to beating our rarest diseases
The future now holds hope for children like Sam Ward, and doctors say many other people are set to benefitJillian Hastings Ward gave birth to her second child, Sam, almost four years ago. For the first few months of his life, the boy appeared to be in good health. “Then we realised that he was not making proper visual contact, and discovered he was blind,” Hastings Ward recalls. Subsequent diagnosis also revealed that Sam was not progressing intellectually. “His brain just couldn’t join the dots,” she says. Today Sam has the mental development of a six-month-old child.At the time of his diagnosis, it was not apparent what was affecting him. Then Hastings Ward and her husband Nick, who live in Bristol, were told about a pioneering scheme launched by the Department of Health. The 100,000 Genomes Project involves several teams of scientists, all of whom have been working towards a remarkably ambitious goal: the sequencing of 100,000 genomes of individuals affected by rare disorders and cancers. Later this month, the project – which was given the go-ahead by prime minister David Cameron in 2012 – will reveal that it has reached its halfway point and has sequenced its 50,000th genome. This news will be followed with the announcement later this year of major initiatives aimed at ensuring that the UK becomes a world leader in genomics medicine. Continue reading...

Lab notes: So long and thanks for all the fish?
Orcas talk! Well, one has, anyway: a study involving a killer whale called Wikie has revealed that orcas can imitate human speech. Researchers have shown that killer whales able to copy words such as “hello”, “one, two” and ‘bye bye’ as well as sounds from other orcas. A great leap for our species, however, is the news that doctors in Newcastle have selected the first patients to undergo treatment which will result in ‘three-person babies’. Both women chosen for the radical therapy carry mutations that cause rare and devastating genetic disease. Another promising advance is the creation of a nasal spray filled soluble nanoparticles of natural painkiller, which could replace addictive opioids. After a successful lab trial, the team are now fundraising for human clinical trials. And finally, two pieces of archaeological excellence. Firstly, a beautiful 1,300-year-old Anglo-Saxon gold and garnet cross – found, intriguingly, on the body of a teenager buried in her own bed – has been given to a Cambridge museum. Secondly (and, indeed, finally) archaeologists believe they may have found a campsite that was home to the architects of Stonehenge. Continue reading...

Astronaut Thomas Pesquet: ‘Earth is just a big spaceship with a crew. It needs looking after’
A stint in space showed the ESA astronaut Earth’s fragility – and convinced him international cooperation is urgently neededAs divisions between them widen on Earth, space must be where countries show they can work together for a common good, France’s best-known astronaut has said in a powerful plea for international cooperation beyond the final frontier.“From up there, the Earth seems so small, so tiny, so … the same,” said Thomas Pesquet, who spent 196 days, 17 hours and 49 minutes in space on the 50th and 51st expeditions to the International Space Station (ISS), returning in June last year.
'Ultra-processed' products now half of all UK family food purchases

We need to do more to close the gap in cancer outcomes | Sanchia Aranda
Money, cultural background and geographic location are crucial in determining survival ratesThis week Cancer Council released new data forecasting cancer survival trends into the future. The statistics, outlining an expected 72% increase in the number of Australians living with cancer or in remission by the year 2040, were startling – but even more concerning are the trends that show the gap between the haves and have-nots when it comes to cancer survival.

So killer whales can talk. Welcome to a brave new world of cross-species chat | Jules Howard
Wikie the orca is more mimic than raconteur, but the potential is awesome. Imagine dolphins tackling politicians on pollutionA bridge in cultures has occurred. A cognitive chasm between intelligent creatures has been crossed. Of all the spectacular times for you to be alive, you happen to have been born in an age when killer whales started talking to the damn dirty apes who were willing to listen. Though this sounds like some sort of sci-fi dream/nightmare, I am here to assure you that this is real. Remain calm, but stay vigilant around all marine mammals at this time. We may be in for a rocky time, as you shall discover.Let us begin by examining the facts. First, it’s true. As you may have heard by now, a captive killer whale called Wikie, housed at Marineland in Antibes, France, is uttering noises that mimic the human sounds “Hello” and “Bye-bye” as well as “One, two, three” plus, apparently, the haunting word “Amy” – the name of its trainer. Predictably, within hours of the release of the scientific paper, Wikie has become something of an online celebrity. Continue reading...

How do outbreaks of seasonal flu differ from pandemics of the past? And how can science help us fight back? Continue reading...
Cultural taboos around food are powerful – could vegans change ours?
As campaigns such as Veganuary become more popular could the way westerners categorise what’s edible start to shift?Yesterday marked the end of “Veganuary”, the campaign to encourage people to try a vegan lifestyle for a month. Year on year the trend has grown. Might those one-month vegans change the habits of the rest of us - by changing what an animal is?Vegans shun all animal-derived products – meat, fish and leather obviously, but also eggs, dairy products, honey and wool. Beers refined using isinglass (derived from fish guts) are out, as would the new UK £5 and £10 notes, if they could be. The term itself was coined back in 1944, bringing together the start and end of the word VEGetariAN, as the next step on. Continue reading...
Super blue blood moon 2018 - gallery
Many parts of the globe caught a glimpse of the moon as a giant crimson globe, thanks to a rare lunar trifecta that combines a total eclipse with a blue moon and super moon. The spectacle, which Nasa has coined a “super blue blood moon,” will grace the pre-dawn skies in the western US as the moon crosses into the shadow of the Earth and turns blood red.

1,300-year-old Anglo-Saxon cross presented to Cambridge museum
Garnet and gold cross discovered in 2011 on the body of a teenage girl buried lying in her own bedA beautiful gold and garnet cross, found on the breast of a teenage girl buried lying on her own bed about 1,300 years ago, has been presented to the Museum of Archaeology and Anthropology in Cambridge.The girl’s grave was found in 2011 by University of Cambridge archaeologists only a few miles from the museum, on land at Trumpington being developed for housing. The bed on which she lay – probably her own – had rotted into the soil centuries ago leaving only the iron supports, but the cross stitched onto the dress which became her shroud was still gleaming.

Palaeontologists on the books and toys that inspired a lifelong love of dinosaurs
Playthings or formative figures? A closer look at the children’s books, films and plastic tat that kickstarted palaeontology careersI remember watching an episode of Noel’s House Party, a Saturday night prime time family friendly TV show with an elaborate set based in the fictional village of Crinkley Bottom. Part variety show, pantomime, talk show, game show with puppets and candid camera skits that aired on British television in the 1990s. One segment of the show involved children undertaking a challenge to win some sort of 90s prize – probably a PlayStation or a lifetime supply of Sunny Delight or something.The challenge in the episode that sticks in the mind is one where a boy who was really into dinosaurs had to identify a bunch of dinosaur models correctly to win. Each dinosaur was under a cover on a plinth and were unveiled in turn for the boy to have a go at identifying. As a precocious young dinosaur fan myself I was glued to the TV under the expectant gaze of my family, waiting for me to deliver the right answers at home. As each one of the dinosaur models was unveiled I knew the correct identifications, as did the hopeful young contestant. He won the prize and everyone on the set proclaimed him as some kind of child genius (as I remember it). Continue reading...
The Beautiful Cure by Daniel M Davis review – how our immune system has shaped world history
A terrific book by a consummate storyteller and scientific expert considers the past and future of the body’s ability to fight disease and heal itselfNature wants to destroy you. Evolution has been driven by aggressive forces in which organisms will enact their livelihood at the expense of yours. Any top 10 list of the greatest killers in human history will not include war or famine, or guns or drugs. Of the voracious beasts that might feed off your flesh, lions and tigers and bears (oh my!) wouldn’t even scrape into the top 20. It is the smallest things in the living world that have had the biggest impact on humankind: malaria, plague, Spanish flu, cholera, tuberculosis, HIV/Aids and smallpox. These diseases are all caused by entities unseen until modern history. From smallest to largest, Aids, smallpox and flu are triggered by viruses, which are tiny compared with the bacteria that cause cholera, plague and tuberculosis, which themselves are dwarfed by the single celled Plasmodium organisms that give us malaria – probably the single most lethal agent in our history.These instruments of death have in effect directed the development of one of the most underappreciated parts of human biology: our immune system. Daniel Davis’s terrific book attempts to redress this understandable oversight. There’s no gentle way of saying this: immunology is hard. Among the many ways we scientifically scrutinise ourselves, it doesn’t have the visceral and artistic merit of anatomy, the mysteries of the mind of psychology or the scientific sex appeal of genetics. The study of the immune system is complex, intricate, meticulous and fiddly. A couple of years of immunology at university was painful enough, and as a grown-up science writer and broadcaster, I confess that I have quietly avoided immunity-related research as much as is polite.

Stronger cannabis linked to rise in demand for drug treatment programmes
