The emphasis on a good night's sleep is nothing new. But now, neuroscientist, Dr Andrew Huberman, has shared one routine that he suggested can make you "better at everything." In a YouTube talk on After Skool, Dr Huberman said he immediately starts his day with a sunrise walk at 6.30am. "Getting outside for a 10-minute walk or a 15-minute walk is absolutely vital to mental and physical health," he shared. Despite coffee being the get-up-and-go drink for most, Huberman says the first beverage he consumes is salty water, as he claims it helps improve bodily functions. "There are certain foundational behaviours - certain dos and don'ts that set the stage for you to be better at everything," he continued. "It always comes back to two elements - that's sleep and what I call non-sleep deep rest. Sleep is the fundamental practice or part of our 24-hour cycle where if you don't get it on a consistent basis, you are down-regulating your ability to do everything." He went on to discuss a "90-minute bout of work," in which he says he turns his phone off to fully optimise this time. "You'd be amazed how much you can get done in 90 minutes if you are focused," he said. Huberman then ensures he gets in an hour's worth of exercise before exposing himself to cold temperatures such as an ice bath. The NHS states that there are no official guidelines regarding how much sleep a person should get each night as everyone is different. "On average, a 'normal' amount of sleep for an adult is considered to be around seven to nine hours a night. Children and babies may sleep for much longer than this, whereas older adults may sleep less," they wrote. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Elon Musk formally renamed Twitter “X” in July, cementing the rebrand by bolting the symbol to the top of the social network’s San Francisco headquarters and replacing Larry the Bird, its mascot since 2012, with a grungy black logo soon afterwards. Linda Yaccarino, X’s new CEO, declared at the time of the rebrand: “X is the future state of unlimited interactivity – centered in audio, video, messaging, payments/banking – creating a global marketplace for ideas, goods, services, and opportunities. Powered by AI, X will connect us all in ways we’re just beginning to imagine.” Mr Musk had already renamed the company itself X Corp in March, six months after acquiring it for $44m, a purchase he described at the time as “an accelerant to creating X, the everything app”, his vision for a multipurpose competitor to China’s WeChat. The decision was just the latest example of the entrepreneur’s preoccupation with the 24th letter of the alphabet: his first business venture was X.com, he shortened the name of Space Exploration Technologies Corp to SpaceX, he launched the Tesla Model X and has a new artificial intelligence startup named xAI. He even calls his son X Æ A-12 just X for short. So what is the obsession about and where did it begin? His first venture, X.com, was an online banking and financial services platform launched in Palo Alto, California, in 1999 that would ultimately be merged with Confinity to become PayPal, which was in turn then sold to eBay for $1.5bn in 2002, Mr Musk using some of the capital he earned as its largest shareholder to found SpaceX. Julie Anderson Ankenbrandt, a former PayPal executive, explained how Mr Musk’s platform got its name in a Quora post in 2016. “Elon, the other founders of the company that was X.com… and I sat around a backroom table at a long-defunct bar called the Blue Chalk in Palo Alto, trying decide what the name of the company should be… and the question at hand was whether to be Q, X or Z dot com,” she wrote. “Finally, when the waitress/female server brought the next round of drinks Elon asked her what she thought, and she said she like[d] X.com. Elon pounded the table and said ‘That’s it then!’ and everyone laughed, but in the end that was pretty much how it was decided.” Not everyone was happy with the decision, according to Mr Musk’s biographer Ashlee Vance, who told NPR: “Everyone tried to talk him out of naming the company that back then because of the sexual innuendos, but he really liked it and stuck with it.” He liked the name so much he bought the X.com domain back from PayPal in 2017 and thanked the company in a tweet, explaining that it had “great sentimental value” to him. The domain now redirects to the social network that has since taken on its old moniker. Elsewhere, the Tesla Model X – a midsize luxury crossover SUV with falcon wing doors – was named so that, with three other models, the range would spell out “S3XY”, giving you an insight into Mr Musk’s gawky sense of humour. As for his son, the boy’s mother Grimes explained in a tweet of her own that the symbol is used in algebra to denote any unknown variable, perhaps suggesting the child is free to grow up to be whatever they choose to be. The rebranding of Twitter to X sparked a great deal of musing about the letter’s possible significance (or lack thereof), with Lora Kelly of The Atlantic writing: “The letter is associated with such varied contexts as Christian symbolism, middle-school-math equations, gender neutrality, pornography, a kiss.” In Psychology Today, Leon F Selzer discussed its “nihilistic” values, noting that it has associations with everything from the Nazi swastika to a skull-and-crossbones danger warning on a bottle of poison to Roman numerals, voting and Christmas (at least when abbreviated to “Xmas”) and therefore can mean everything and nothing. Meanwhile, in The New York Times, Stella Bugbee suggested the choice was arguably a bit dated and perhaps represented a case of Mr Musk showing his age as a member of, appropriately enough, Generation X. “For marketing purposes in the 1990s, X had a certain cool,” she explained. “It conferred a rejection of authority.” While that observations rings true of such turn-of-the-millennium cultural detritus as, say, the arrival of Microsoft’s XBox in 2001 or Vin Diesel’s action film XXX (2002), it has also been used in the same way before and since: think of country star Loretta Lynn’s notoriety-courting 1972 single “Rated X” or the cult 1980s Los Angeles punk band X, for instance, or the more recent Ti West horror film X (2022). As Lora Kelly observed: “X both reinforces absence and electrifies objects with meaning. It is sacred and profane.” Read More Elon Musk ‘borrowed $1bn from SpaceX’ at same time as Twitter acquisition SpaceX abandons YouTube for live streams of launches in favour of X/Twitter Elon Musk threatens to sue the Anti-Defamation League over lost revenue on X Elon Musk ‘borrowed $1bn from SpaceX’ at same time as Twitter acquisition Starship ‘ready to launch’, Elon Musk says Elon Musk vows to sue ADL for calling him antisemitic over X campaign

If your relationship is feeling stale, “Alphabet Dating” has been hailed as a great way to inject some fun back into quality time. When in a long-term relationship, it can sometimes be difficult to maintain the fun and spontaneity of the earlier years and to fall back on routines. But content creator Stephanie Booe has shared her tip for getting the spark back with what she has called “alphabet dating”. Alphabet dating involves going through the alphabet and picking a date activity that corresponds to that letter. In one video about the dating trick, Booe revealed that on their A-themed date, she and her partner ate appetisers before going axe-throwing. Sign up to our free Indy100 weekly newsletter She explained: “We went to a new restaurant, ordered a few appetizers instead of entrees and then we went axe throwing for the first time ever! “This was such an easy and simple little way to uproot us from our comfort zone and to do something we wouldn’t normally do.” She also added: “Hear me when I say that this doesn’t have to be big, fancy, or expensive. That’s part of the challenge! You don’t have to go out every week, you can easily find ways to do these themed date nights at home.” One Instagrammer wrote: “I love this idea!” Another said: “I love this idea! Could also easily be turned into a snack + movie-night-in with the coordinating letter if needed.” Booe recommended that partners take turns to plan dates, taking alternate letters in the alphabet. Last year, the theory of alphabet dating went viral on TikTok after users such as Abby Benson-Schwallie shared their list of creative alphabet date ideas. @abbymbenson here are is ur alphabet date list!! ?#alphabetdates #love #couple #fyp #trending #foryoupage On her list, Benson-Schwallie listed ideas such as, “Christmas movie and cider”, “Hot wings and horror” and “Nostalgia”.

Scientists have developed new ultrasound technology that can induce immediate “hibernation”, they say. The system can be aimed at the head and bring on “torpor” a state similar to hibernation where mammals suppress their metabolism, reduce their body temperature and slow down other processes. The researchers behind the new system successfully brought it on in mice and rats, after pointing the ultrasound pulses at the animals’ heads. They suggest that it could work in humans – and might have important applications for long-distance space flight or medicine, they say. While further work is needed to understand how it might work on people, they suggest that it could be used when people have experienced acute emergencies or severe disease, for instance. If someone is in a car accident, for instance, they could essentially be put on ice until their organs are used for transplantation, for instance. It might also be useful in long journeys through space, where it would help reduce the amount of resources that people might stay alive if they are travelling to Mars or other distant locations. Mammals and birds keep high body temperatures and burn through a lot of energy. That characteristic is useful host of ways, but almost means that they require a lot of food and other resources. Some animals are able to limit the drawbacks of that situation by inducing torpor, which turns down many of those processes. It means that they use less energy, but are able to come back to living as normal after, without damage to their body. Humans are not able to do that. But if they were, it would be incredibly useful – which has led to the search for a noninvasive, safe and reliable way of inducing that state. The scientists found that directing ultrasound pulses at mice’s heads for around 10 seconds brought on the same conditions as torpor, with their heart rate slowing, their body temperature cooling and their metabolism slowing. They also built a special system that was able to measure that body temperature and send more of those pulses if a mouse appeared to be coming back to normal. Without that, however, the mice would wake back up again, returning to normal metabolism and body temperature. There are still a host of dangers, however. Experiments have shown that it is dangerous to bring animals back from those deep “torpid” states, and that they might not recover. If the mice were in cold environments, for instance, they did not spontaneously wake up. And any experiments in humans would be at risk of repeating those safety issues for people. The work is described in a new paper, ‘Induction of a torpor-like hypothermic and hypometabolic state in rodents by ultrasound’, published in Nature.
