Nasa’s James Webb telescope’s most recent image of a distant star system has thrown up more questions than answers – literally. The image is of the star system Herbig Haro 46/47, and includes a cosmic object that is shaped like an actual question mark. Scientists think the entity could be a distant galaxy, or two galaxies interacting with one another. One larger galaxy could be distorting the cosmic cloud and gas of the other, for example, forming a shape similar to a question mark.

Additional follow-up would be required to figure out what it is with any certainty. Webb is showing us many new, distant galaxies – so there’s a lot of new science to be done,” the US’s Space Telescope Science Institute, which manages Webb’s science operations, told Space.com. The star system in the foreground, dubbed Herbig-Haro 46/47, was captured by the Webb telescope’s powerful infrared cameras and consists of two young stars pulled to each other by gravity as they spin. An image reveals the stars as buried deeply, appearing as an orange-white splotch, surrounded by a disk of gas and dust that continued to add to their mass. JWST Finds a Cosmic Question Mark and a Starry Fountain www.youtube.com “Herbig-Haro 46/47 is an important object to study because it is relatively young – only a few thousand years old,” Nasa said in a statement. The pair of actively forming stars have two-sided orange lobes which were created by earlier ejections from these stars. Scientists said the two young stars could give more insight into how stars gather mass over time, given the fact that the process usually takes millions of years. Have your say in our news democracy.

Illicit free streams for Barbie, Oppenheimer and other summer blockbuster movies pose a risk to people attempting to watch them online, cyber security experts have warned. Searches for how to watch the films for free were tracked by security firm NordVPN, revealing links leading to sites containing malware and other malicious software. The worst impacted movie was Guardians of the Galaxy: Vol. 3, according to the researchers, with links shared on Twitter containing the most number of phishing warnings, malicious links and malware concerns. The Super Mario Bros. Movie had the second-most security threats linked to it, followed by Barbie, Indiana Jones and the Dial of Destiny, John Wick: Chapter 4, Transformers: Rise of the Beasts, The Little Mermaid, Oppenheimer, Mission Impossible - Dead Reckoning Part One, and Killers of the Flower Moon. Illegal online streams that allow people to watch films for free have become a popular way for cyber criminals to exploit web users in recent years. Several illicit platforms that mimic the functionality of Netflix and other legitimate streaming services offer ways to watch films and TV shows with little cyber security risk to users, however links shared on social media sites like Twitter and Reddit can often lead to fake websites that attempt to steal financial or other sensitive information. “Trying to watch films this way is like searching for a needle in a haystack, with few of the links providing a watchable movie,” said Adrianus Warmenhovem, a cyber security advisor at NordVPN. “Most of these blockbusters will soon be available on reputable streaming platforms like Netflix, Disney+ and Amazon Prime Video, so we suggest film fans be patient and enjoy these movies safely. Always stay cautious when clicking on a link, even on a trustworthy website, and use anti-malware tools.” Major sporting events are particularly vulnerable to cyber attack attempts, with searches for free live streams surging in the build up to big fights, football matches and races. The most popular form of piracy is websites hosting free streams of films and TV, accounting for more than 80 per cent of all piracy, according to figures published earlier this year. Piracy research firm Muso revealed that illegal streaming of films grew 38.6 per cent between 2021 and 2022, while visits to free streaming sites rose by nearly 9 per cent. This trend is expected to continue in 2023, early data suggests. Read More World Cup plagued by 'industrial-scale' piracy Premier League caught up in 'world's biggest piracy operation'

A paralysed man has regained feeling in his limbs after an AI-enabled implant was placed in his brain. The first-of-its-kind clinical trial used novel stimulation technology to restore the sense of touch and movement to 45-year-old Keith Thomas, who was paralysed from the chest down in 2020 after diving into a swimming pool. After living as a quadriplegic for more than a year, Mr Thomas was approached by the Feinstein Institutes for Medical Research in the US to take part in a study that proposed a double neural bypass to re-route signals from the brain in order to restore movement and sensation. Artificial intelligence was able to re-link his brain to his body through microchips implanted into his brain during a 15-hour surgical procedure. “This is the first time the brain, body and spinal cord have been linked together electronically in a paralysed human to restore lasting movement and sensation,” said Chad Bouton, a professor at the Institute of Bioelectronic Medicine at the Feinstein Institutes, who led the clinical trial. “When the study participant thinks about moving his arm or hand, we ‘supercharge’ his spinal cord and stimulate his brain and muscles to help rebuild connections, provide sensory feedback, and promote recovery. This type of thought-driven therapy is a game-changer.” Over 100 million people around the world currently live with some form of paralysis or movement impairment, with the scientists hopeful that the new method could provide new pathways toward improving the condition of many of them. Mr Thomas has already regained more than double his arm strength since enrolling in the clinical trial, and also reported feeling sensations in his forearm even when the system was switched off. “There was a time that I didn’t know if I was even going to live, or if I wanted to, frankly,” said Mr Thomas. “Now I can feel the touch of someone holding my hand. It’s overwhelming.” Read More Paralysed man communicates first words in months using brain implant: ‘I want a beer’

Scientists have revealed why people should head to sleep at the same time every night. A study by Kings College London which involved 1,000 adults, aimed to find whether "social jetlag" (the shift between sleep patterns on work days and free days) can have an impact on health. In doing so, researchers discovered that sleeping at the same time and a healthy diet could decrease the risk of disease. They found that even a 90-minute difference in the mid-point of sleep could impact the types of bacteria in the gut. They analysed participants' sleep, blood and stool samples, and logged everything they consumed in a food diary. Those with "social jetlag" (16 per cent) appeared to have a diet filled with potatoes, crisps, chips and sugary drinks. Other studies have suggested that social jetlag is linked to weight gain, illness and mental fatigue. Sign up for our free Indy100 weekly newsletter Dr Wendy Hall, senior author from King’s College London, said: "We know that major disruptions in sleep, such as shift work, can have a profound impact on your health. "This is the first study to show that even small differences in sleep timings across the week seems to be linked to differences in gut bacterial species. "Some of these associations were linked to dietary differences but our data also indicates that other, as yet unknown, factors may be involved. "We need intervention trials to find out whether improving sleep time consistency can lead to beneficial changes in the gut microbiome and related health outcomes." Kate Bermingham, study author and senior nutrition scientist at ZOE, said: "Sleep is a key pillar of health, and this research is particularly timely given the growing interest in circadian rhythms and the gut microbiome. "[Social jetlag] can encourage microbiota species which have unfavourable associations with your health," she continued. Have your say in our news democracy.
