    The Elon Musk Show review: Searching for the man who is Elon Musk

    As Elon Musk becomes wealthier and more powerful, we need to know more about the man whose projects are transforming the world. But as a new documentary shows, it is hard grappling with the reality of someone with such disparate labels as hero, villain, or superhuman genius

    In the new BBC2 series The Elon Musk Show, aerospace engineer Jim Cantrell recalls being approached by Elon Musk, then an entrepreneur interested in space, about his “ultimate goal of making humanity a multiplanetary species”.
    At the time, the ex-NASA employee was privately dismissive, as he effectively conveys on camera with an onanist hand gesture. Cantrell recalls, with a rueful chuckle, mishearing his name: “‘Ian Musk’ is what I thought he said.”

    Why I am keen to get my hands on genetically modified purple tomatoes

    The first home-grown genetically modified food may be on the horizon, in the form of purple tomatoes, finds Clare Wilson

    THE end of the tomato season is approaching in the UK, and I am weighing up the performance of the different varieties I grew and deciding which seeds to buy again. Next spring, US gardeners may have a new option to consider: the first genetically modified seeds for home growers could go on sale there, in the form of bright purple tomatoes.
    GM food can be controversial, but the scientific consensus is now that plants with modified genes are no more liable to be unhealthy for us than unmodified ones. Foods containing GM ingredients, such as soybeans and maize, … More

    12,000 genetic variants affect height in people with European ancestry

    Over 12,000 genetic variants play a role in height differences among people with European ancestry, though these variants have a much smaller influence in people with other ancestries

    A study of 5.4 million people has revealed that over 12,000 genetic variants have an influence on height differences among those with European ancestry. The findings could deepen our understanding of medical conditions affecting growth.
    “We have discovered most of the common genetic variants associated with height in European ancestry populations,” says Loic Yengo at the University of Queensland in Australia. “We can predict someone’s height better than using the average height of their biological parents.”
    Yengo and his colleagues used a computational analysis to compare the height and genomes of 5.4 million people, 75 per cent of whom had mainly European ancestry. The team collected data from previous studies or from the DNA testing company 23andMe.Advertisement
    This revealed 12,111 common genetic variants – each found in more than 1 per cent of the population – that could explain 40 per cent of height differences among people with European ancestry. Each genetic variant was a single nucleotide polymorphism, where the specific DNA base at a position in the genome varies across a population.
    The findings support earlier studies which predicted that 40 to 50 per cent of height variation among people could be explained by common genetic variants.
    “Of the remaining 60 per cent in height variation, 40 per cent is [thought to be] from less common genetic variants [that occur in less than 1 per cent of the population] and 20 per cent is from the environment,” says Yengo, meaning due to factors such as poor nutrition.
    The team also found that the common genetic variants associated with height made up about 20 per cent of the genome and were clustered in regions linked to medical conditions affecting skeletal growth.
    “Our study can help us understand the biology of growth. Growth processes are important in human development and can be altered by diseases,” says Yengo. The findings could also shed light on why being taller seems to increase the risk of conditions like coronary heart disease.

    However, the genetic variants in the study could only explain about 10 per cent of the height differences among those with East Asian, Hispanic, African and South Asian ancestry.
    Although the study is the most genetically diverse of its kind, further work is needed to focus more on non-European ancestries, says Yengo.
    “The immense size of this study coupled with the strong genetic basis of height have led to a big breakthrough in genomic research – the first complex human trait where most of the genetic basis has been identified for people of European descent,” says Karoline Kuchenbaecker at University College London.

    Has a recent glut of fantasy shows pushed sci-fi out of the limelight?

    HBO’s Game of Thrones turned fantasy into a cultural phenomenon on the small screen; now, rival platforms are rushing to catch up. Are sci-fi fans being left out in the cold, asks Bethan Ackerley

    THROUGHOUT the history of television, science fiction has fared far better than fantasy. Its place in the mainstream was cemented by Star Trek and Doctor Who, not to mention more recent masterpieces like Battlestar Galactica. It is only in the past decade that we have seen a fantasy series become a true cultural phenomenon, thanks to Game of Thrones. No other show in the genre has had such an impact.

    I am planning my wife's woodland burial, but green funerals are costly

    My late wife was an environmentalist and wanted an eco-friendly funeral. I have seen to her wishes, but a woodland burial isn’t possible for all those who would like one, writes Graham Lawton

    FOLLOWERS of this column may have noticed that I have been absent for a while. I have been caring for my wife, Clare, who fell seriously ill about a year ago. She declined at frightening speed and died in August aged just 53. We were together for 30 years, married for 24 and had three sons together. My grief is immense.
    She developed a rare and not-well-understood condition called nociplastic pain or central sensitisation, which is when the way the brain produces pain goes into overdrive. Even tiny amounts of “normal” pain are experienced as massive, overwhelming agony. Ditto negative emotions, tiredness and illness. Painkillers don’t work, not even intravenous morphine. The condition was only recognised as a separate category of pain about a decade ago and medical science can’t offer very much. Clare got sucked into a vortex of ever-escalating and never-ending pain, which led to anxiety, panic attacks, depression and drug addiction, all of which just served to ratchet up the pain even further. Once nociplastic pain has its claws in there is no easy escape. Clare couldn’t see one, and she ended her own life.
    I am planning her funeral as I write this. She was an environmentalist and wanted to be buried in a biodegradable coffin, preferably in woodland. It turns out that this is possible – our local cemetery in north London has a lovely woodland plot. But it is also phenomenally expensive – the coffin alone is £550. Clare had good life cover, so I have seen to her wishes. But I am sure a woodland burial is beyond the means of many people who want to donate their body to the earth.Advertisement
    The default option is cremation. At present, about 80 per cent of the people who die in the UK are cremated, which is much cheaper, but extremely damaging to the environment. An 80-kilogram body contains approximately 14.4 kilograms of carbon, which is all converted to carbon dioxide when combusted. Crematoriums also use natural gas to burn the body and coffin. According to National Geographic, a single cremation produces 240 kilograms of CO2, about the same as burning 100 litres of petrol.
    Cremations also produce toxic pollutants, principally mercury from dental fillings. Filtration systems can prevent this from venting to the atmosphere, but not all crematoriums have them.
    Traditional burials are less damaging, but don’t get a clean bill of environmental health either. If the body is embalmed, the formaldehyde leaches into the soil as the body decomposes. Coffins usually have metal fittings that also pollute the earth. Making coffins and headstones consumes considerable amounts of energy.
    Clare’s funeral won’t be totally eco-friendly. Her coffin is made of water hyacinth leaves produced by a certified fair-trade grower in Bangladesh, so I guess will rack up a fair amount of coffin miles. We will travel to the cemetery in petrol-powered vehicles. But in other respects, it will be impeccably green. Her body hasn’t been embalmed, the coffin is 100 per cent biodegradable and a woodland grave will quickly turn her into compost. She had excellent teeth, so mercury pollution won’t be a problem.
    As well as being eye-wateringly expensive (my eyes have been doing a lot of watering lately), woodland burials are also in short supply. We are lucky our cemetery has a woodland plot; not all do.
    Indeed, a shortage of burial plots of any kind is becoming a serious problem. In a 2019 article in the Journal of the Royal Society of Medicine, John Ashton warned that England and Wales’s graveyards and cemeteries are filling up. With 100,000 burials annually, there will probably be no room in a few years.
    One solution, according to Ashton, is to take inspiration from the Victorians, who responded to similar pressures on churchyards by creating large urban cemeteries, including London’s so-called magnificent seven. These have served us well, but are almost full. The modern equivalent, says Ashton, is to develop green burial corridors alongside roads, railways and footpaths. I am not sure I would want my loved ones buried by a major road, but if it increases the availability and affordability of eco-burials, I am for it.
    I mentioned that we had three sons together. The first of them died at a very young age and is also buried in the same cemetery. I take a little bit of comfort from the fact he is going to be reunited with his mum and that I can visit their graves at the same time.
    As for other silver linings, I got a BOGOF deal on the plot and will one day have my own eco-funeral and be buried alongside Clare. Farewell my love, we will be reunited in the woods one day.
