Criticized for giving into governments' censorship demands, Elon Musk on Sunday claimed that Twitter has "no actual choice" about complying those requests.

Rare footage of an octopus having a 'nightmare' has been captured and it is fascinating scientists who study the creatures. The footage comes courtesy of The Rockefeller University in New York where an octopus named 'Costello' was studied for 24 hours a day in a laboratory. In papers published by bioRxiv, they found that on at least four occasions the octopus woke up abruptly and began flailing its tentacles, changing colour, shooting black ink into the water and displaying "antipredator and predatory behaviors." The experts put this behaviour down to temporary stress which they believe was likely caused by a bad dream or even a memory from a previous traumatic moment.

And then he just got up like nothing had happened, and he resumed his day as normal." Compilation of the four abnormal sleep-associated episodes documented in a male Octopus insularis. www.youtube.com One thing the scientists did note is that when Costello arrived in the lab he appeared to be recovering from several severe injuries having lost the majority of two of his tentacles following an attack. When suggesting that Costello could have been dreaming about the attack the scientists noted: "can result in long-term behavioral and neural hypersensitivity." There has also been suggestions from Robyn Crook an associate professor of biology at San Francisco State University, who was not involved in the study, that Costello's behaviour could be down to something called senescence, which is when an octopus' body begins to break down before their death. Ramos concluded that he could not "exclude that senescence could be one of the drivers of this." This is not the first time footage of this nature has been captured. Back in 2019, PBS shared incredible footage of an octopus changing colour while it appeared to be dreaming. Have your say in our news democracy.

Taylor Swift fans have shared feelings of forgetfulness after seeing the pop-star performing on her highly anticipated Eras Tour. Speaking to Time, Jenna Tocatlian, 25, spoke about her experience seeing Swift at Gillette Stadium in Massachusetts. Speaking about one of Swift’s nightly surprise songs At the concert that Tocatlian attended the song was 'Better Man', but she said: ‘If I didn’t have the 5-minute video that my friend kindly took of me jamming to it, I probably would have told every that it didn’t happen.’ She added that as she waited to leave the stadium, during an hour-long wait, she found it difficult to grasp the reality of a night she had waited so long to experience. ‘It’s hard to put together what you actually witness,’ she told Time. Sign up to our free Indy100 weekly newsletter It seems Tocatlian isn’t the only one experiencing ‘post-concert amnesia’. Taking to social media, many users have shared their inability to recall the events of the show, from small details to even significant parts of the concert. Some described having feelings of guilt after waiting so long to attend the show and leaving without explicit memories. Ewan McNay, an associate professor in the psychology department at the State University of New York in Albany, told Time that the experience may be a result of too much excitement. He explained that ‘this is not a concert-specific phenomenon - it can happen any time you’re in a highly emotional state.’ This is because as a result of feelings of excitement, the body’s stress levels increase, which in turn causes neurons associated with memory to start firing indiscriminately. McNay shared that this makes forming new memories ‘really hard.’ The biological explanation for this occurrence is due to the body seeing excitement as a state of stress. The body then starts pumping out the brain’s favourite molecule for memory: glucose. Because the body thinks it’s stressed, it doesn’t want to waste energy on memory formation. Your vagal nerves, which regulate internal organ functions, also become stimulated as a result of the perceived stress. All this causes the part of your brain responsible for emotional processing - known as your amygdala - to release a neurotransmitter called norepinephrine. This helps to categorise memories as having high emotional content, increasing the likelihood that they’ll be stored vividly in your mind. However, McNay goes on to explain that too much of this chemical release can actually invest the process, especially if caffeine or alcohol are included. Which leads to your brain struggling to create and store new memories. For those who want to try and have a better memory of an important event, whether it’s seeing Taylor Swift, or getting married, McNay shared some helpful techniques. He says to try and achieve a ‘semi-meditative state’ and relaxing. He also adds that physical responses such as screaming at a concert tells the body that you must be scared. If you stand still in a more relaxed state, your brain will know not to get too excited, and aid the formation of new memories. Have your say in our news democracy.

Twitter boss Elon Musk, who has often touted himself as a champion of free speech, said he had no "actual choice" when accused of caving in to censorship demands made by authoritarian governments. Since the billionaire's takeover in October last year, Twitter has approved 83 per cent more censorship requests from governments such as Turkey and India, El Pais reported. The company reportedly received 971 requests from governments, fully acceding to 808 of them and partially acceding to 154. The year prior to Mr Musk taking control, Twitter agreed to 50 per cent of such requests, which was in line with the compliance rate indicated in the company’s last transparency report. The report, shared by Bloomberg columnist Matthew Yglesias, evoked an angry reaction from Mr Musk. Mr Yglesias tweeted the report with the caption "I’m a free speech absolutist", quoting the Twitter boss. The world's second-richest person shot back, writing: "You're such a numbskull. Please point out where we had an actual choice and we will reverse it." The columnist responded: "Look, I’m not the one who bought Twitter amidst a blaze of proclamations about free speech principles. "Obviously you’re within your rights to run your business however you want." Mr Musk has repeatedly reiterated his backing for free speech both before and since the $44bn acquisition of Twitter. The “absolutist” quote refers to a tweet in March 2022 in the wake of Vladimir Putin’s unprovoked invasion of Ukraine. "Starlink has been told by some governments (not Ukraine) to block Russian news sources. We will not do so unless at gunpoint," Mr Musk tweeted. "Sorry to be a free speech absolutist." Yet Twitter has been accused of helping incumbent Turkish president Recep Tayyip Erdogan stifle criticism by blocking several accounts in the two days before the country’s hotly contested general election. “In response to legal process and to ensure Twitter remains available to the people of Turkey, we have taken action to restrict access to some content in Turkey today,” Twitter’s global government affairs announced, without explaining which tweets would be blocked. Following severe criticism, Mr Musk alleged Twitter has “pushed harder for free speech than any other internet company, including Wokipedia”. Earlier this year in India, Twitter complied after Narendra Modi’s government used emergency powers to ban content related to a BBC documentary on social media. The two-part documentary included a previously unpublished report from the UK Foreign Office that held Mr Modi “directly responsible” for the “climate of impunity” that enabled communal violence in Gujarat state. The riots in February 2002 killed over 1,000 people – most of them Muslims – while Mr Modi was chief minister of the state. Justifying the consent Mr Musk said: "The rules in India for what can appear on social media are quite strict, and we can’t go beyond the laws of a country." He said doing so would put his staff at risk. “If we have a choice of either our people going to prison or us complying with the laws, we will comply with the laws.” Read More Elon Musk tweets quote by neo-Nazi wrongly attributed to Voltaire Erdogan declared winner of Turkey presidential run-off – extending his 20 years in power India uses emergency powers to ban anyone from sharing clips of BBC Modi documentary Elon Musk tweets quote by neo-Nazi wrongly attributed to Voltaire Elon Musk’s Neuralink brain chip company gets FDA approval for human testing AOC jokes more people watched her gaming online than listened to DeSantis launch
