A huge bubble of galaxies that is one billion lightyears across could be a remnant of the ripples caused by the Big Bang, according to astronomers who have mapped the structure. The structure, named Hoʻoleilana by University of Hawaii scientists, is thought to have been caused by so-called Baryon Acoustic Oscillations (BAOs). These were ripples in the particles of the early Universe in the period following the Big Bang, when planets, solar systems and galaxies were not yet fully formed. As the ripples went outward, they created areas of density in the particles, causing bubble-like structures in which galaxies eventually coalesced. Until now, the BAOs were just a prediction – part of the wider Big Bang theory. No specific structures in the Universe had been found which mimicked their patterns. But Hoʻoleilana fits the description of these huge cosmic bubbles perfectly, according to Brent Tully, who led the study at the University of Hawaii’s Institute for Astronomy. “We were not looking for it. It is so huge that it spills to the edges of the sector of the sky that we were analyzing,” he said. “As an enhancement in the density of galaxies it is a much stronger feature than expected. The very large diameter of 1bn light years is beyond theoretical expectations. “If its formation and evolution are in accordance with theory, this BAO is closer than anticipated, implying a high value for the expansion rate of the universe.” The bubble is absolutely huge. It is made up of several superclusters, structures which themselves are thought to be among the Universe’s largest arrangements of matter. This includes the Hercules Supercluster, the Corona Borealis Supercluster and the Sloan Great Wall. All of these structures contain thousands of galaxies. In the middle of Hoʻoleilana sits the Bootes Supercluster and the Bootes Void, an immense space of nothingness which is an incredible 330m lightyears across. Daniel Pomarede, from the CEA Paris-Saclay University, who contributed to the research, said: “It was an amazing process to construct this map and see how the giant shell structure of Ho’oleilana is composed of elements that were identified in the past as being themselves some of the largest structures of the universe.” The research was published on 5 September in The Astrophysical Journal.

A wind turbine in China has set a new world record for the most amount of electricity generated in a single day, after operating during typhoon conditions. The Goldwind GWH252-16MW turbine, which was installed at an offshore wind farm in Fujian Province in June, produced 384.1 megawatt hours in a single day – enough to power roughly 170,000 homes. The record was achieved on 1 September, according to state-owned power company China Three Gorges (CTG), surpassing the previous record set by Danish company Vestas in August. The turbine’s rotor has a diameter of 252 metres – more than double the diameter of the London Eye – and at full speed each blade can reach up to 70 per cent of the speed of sound. The record-breaking wind turbine features an innovative design that allows it to adjust its blades in real time when winds reach high speeds. This allowed it to continue operating during Typhoon Haikui last week, during which conventional turbines were forced to shut down. “We are closely monitoring critical components like the main control programme, pitch system and generators to gradually lift power restrictions while ensuring operational safety,” a spokesperson for Goldwind told the South China Morning Post. Figures from the Chinese Wind Energy Association show that China installed more than 11,000 wind turbines last year, 90 per cent of which were at onshore wind farms. Separate figures from the International Energy Agency (IEA) suggest that China added nearly three times as much wind capacity in 2022 compared to the European Union, and accounts for more than a third of all of the world’s installed wind capacity. Projections from the agency indicate that electricity from wind and solar will double over the next five years, providing almost 20 per cent of global power generation by 2027. “China is forecast to install almost half of new global renewable power capacity over 2022-27, as growth accelerates in the next fice years,” a recent IEA report noted. “Very ambitious new renewable energy targets, market reforms and strong provincial government support provide long-term revenue certainty for renewables. In most Chinese provinces, utility-scale renewables are cheaper than regulated coal electricity prices, driving rapid adoption. In the main forecast, China is expected to reach its 2030 target of [renewable] capacity five years in advance.” Read More How tech could turn our homes into renewable energy power stations World’s first solar powered hybrid truck tested on public roads Period and fertility tracking apps scrutinised over data security concerns AI can help generate synthetic viruses and spark pandemics, warns ex-Google executive Google boss says he wants to make people ‘shrug’

As the biggest YouTuber out there, MrBeast is known for his eye-catching thumbnails. However, he recently noted one change that is causing even more people to view his videos. The 25-year-old - whose real name is Jimmy Donaldson - has over 181m subscribers and so knows what causes viewers to click on his latest piece of elaborate content. Often, MrBeast - like many other YouTubers - can be seen pulling a shocked face to attract and intrigue viewers to watch in his thumbnail images. But after testing out different versions for his videos, he shared how the classic pose isn't as effective as he thought, explaining that thumbnails with his mouth shut do better. “I closed my mouth on all my thumbnails and the watch time went up on every video lol,” MrBeast said on Twitter/X. “My mouth is now closed in all my thumbnails but the war has just begun. We must not rest until mouths are closed in everyone’s thumbnails." In the tweet, he shared a screenshot of the different combinations where YouTube declared the thumbnails of him flashing a smile were a "winner," compared to the traditional shocked face. "Now all YouTubers will shut their mouths," one user jokingly tweeted, to which the MrBeast replied: "Thank god." When someone asked the YouTuber if the shocked face thumbnail era was over, he answered: "Seems like it, here’s more results. Now that I can actually A/B test thumbnails I don’t have to guess and I just test and see what people want." The YouTuber admitted: "My mouth would have closed years ago if I had this tool."

The UK’s data protection regulator is to review period and fertility tracking apps over concerns around the data security of such platforms. The Information Commissioner’s Office (ICO) said the review was in response to figures it had obtained from its own research, which found that more than half of women using these apps had concerns over how their data was being used. The data protection watchdog’s research showed a third of women have used apps to track their periods or fertility, and more than half of those who have used an app believed they had noticed an increase in baby or fertility-related adverts since signing up, with 17% said they had found this distressing. The ICO said its poll showed concerns around data use and how secure their data was were named as bigger fears among women than the cost of these apps or ease of use. We want to make sure women can use these services with confidence, so we’re calling for people to share their experiences Emily Keaney, ICO The regulator is now urging users to come forward and report their own experiences using tracking apps as part of a call for evidence. It said it had also contacted companies who provide period and fertility tracking apps to find out how they are processing users’ personal information. The ICO said the focus of its work would be to identify if there was the potential for harm and negative impact on users. “These statistics suggest data security is a significant concern for women when it comes to choosing an app to track their periods or plan or prevent pregnancy,” Emily Keaney, ICO deputy commissioner of regulatory policy, said. “That’s not surprising, given the incredibly sensitive and personal information involved. “We want to make sure women can use these services with confidence, so we’re calling for people to share their experiences. “This will help us understand whether there are areas that need improvement – from how easy it is to navigate privacy policies to whether people have experienced upsetting and unexpected targeted advertising. “We also know some users feel these apps bring many benefits and we’d like to hear about these too. “As with all health apps, we would expect organisations to safeguard their users’ privacy and have transparent policies in place. “This review is intended to establish both the good and bad of how the apps are working currently. “Once we have more information, we will explore next steps, but we will not hesitate to take regulatory action to protect the public if necessary.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Russian cyber-attacks ‘relentless’ as threat of WW3 grows, expert warns Warner Music sign first digital character Noonoouri and release debut single Met should thoroughly investigate cyber security practices, say experts

SUNNYVALE, Calif.--(BUSINESS WIRE)--Sep 7, 2023--

India’s Vikram lunar lander has recorded movement below the surface of the Moon – but it’s probably not aliens. Experts think the movement is seismic activity – the lunar equivalent of earthquakes. It is the first time humans have detected the so-called moonquakes since the 1970s. The new activity was recorded by the Vikram lander’s onboard instrument for lunar seismic activity, a piece of kit designed “to measure ground vibrations generated by natural quakes, impacts, and artificial events,” the Indian Space Research Organization (ISRO) said. India’s Chandrayaan-3 mission saw it land the Vikram and its sister craft, the Pragyan rover, last month, becoming the first nation to land near the Moon’s little-explored South Pole. It also makes India just the fourth nation to land on the Moon, alongside the US, the former USSR and China. The seismic activity is the first recorded since the US Apollo programme, which ended in 1977. Those recordings yielded valuable data about the Moon’s makeup. Scientists have been able to theorise that the Moon has an inner core which is much less dense than the Earth’s and which is about 500km across. On Earth, seismic activity is caused by the shifting of the planet’s tectonic plates. But on the Moon, things are a bit different. The quake could be caused by thermal activity from the Sun, or by tidal stresses caused by Earth’s gravity, cracking the planet and causing the pieces to rub together. The team noted that the event is currently under investigation. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
