Twitter rival Bluesky has been forced to temporarily pause sign-ups after experiencing a surge of interest following Elon Musk’s decision to introduce new limits to his social network. The tech billionaire began limiting the number of tweets people can read on Saturday, claiming that it was necessary to address “extreme levels of data scraping and system manipulation”. The move prevents unverified users from seeing more than 600 Twitter posts a day, while paid subscribers can view up to 6,000. It prompted renewed interest in rival apps, including Mastodon, whose creator said 110,000 new users joined the platform in just one day. Bluesky, which was founded by former Twitter chief executive Jack Dorsey, is currently in private beta, meaning people can only sign up if they have an invite code from another user. “We will temporarily be pausing Bluesky sign-ups while our team continues to resolve the existing performance issues,” the company said over the weekend. “We’ll keep you updated when invite codes will resume functionality. We’re excited to welcome more users to our beta soon!” Among those making the transition from Twitter to Bluesky to Twitter is Paul Cooper, host of the Fall of Civilization podcast. Last month, Mr Musk encouraged the history podcast to “please upload your podcasts” to Twitter, though Mr Cooper replied that he considered the platform “too compromised” to make such a move. “It’s become a safe haven for hate speech, and meanwhile crypto scammers and bots are paying to be boosted to the top of replies,” the podcast host wrote. “Everything that once made Twitter special seems to be leaching away.” Mr Musk said the limits introduced for Twitter users would be temporary, though did not specify when they would be removed. Twitter responded to a request from The Independent for more information with its customary poop emoji. Read More Twitter alternative Bluesky launches as Android app

Chaos at Twitter has seemingly led to a new surge of activity on Mastodon, a rival social network, according to its creator. Mastodon has seen some success since Elon Musk took over at Twitter, as users search for alternatives. Unlike its rival, Mastodon has a decentralised structure that relies on users to support and build the network itself. “Looks like Mastodon‘s active user base has increased by 110K (110,000) over the last day. Not bad,” Eugen Rochko, creator and chief executive of Mastodon, wrote on the platform late on Sunday. “I would prefer it if Elon Musk was destroying his site during the work week. This isn’t the first time,” another post from Rochko read. On Saturday, Twitter boss Elon Musk announced new limits on the number of posts accounts can read in a day. Previously, he had expressed displeasure with artificial intelligence firms like OpenAI, the owner of ChatGPT, for using Twitter’s data to train their large language models. Musk took over Twitter in October 2022. Since then, his erratic management style has prompted some users and advertisers to turn away from the site. Mastodon has similar features to Twitter but rather than being controlled by one company, it is installed on thousands of computer servers, largely run by volunteer administrators who join their systems together in a federation. After Mr Musk’s announcements over the weekend, Twitter is also now requiring people to log on to view tweets and profiles - a change in its long-time practice to allow everyone to peruse the chatter on what Mr Musk has frequently touted as the world’s digital town square. The restrictions could result in users being locked out of Twitter for the day after scrolling through several hundred tweets. Thousands of users complained on Saturday of not being able to access the site. In a tweet on Friday, Mr Musk described the new restrictions as a temporary measure that was taken because “we were getting data pillaged so much that it was degrading service for normal users”.

The universe went in “extreme slow motion” at its beginning, and has dramatically sped up since, scientists have found. The discovery, predicted by Einstein’s general theory of relativity, was finally confirmed after scientists observed the universe soon after the Big Bang. Einstein’s theory suggests that we should be able to see the distant universe, when it was much older than it is today, running much more slowly. But scientists have not been able to actually look that far and confirm the theory. Now scientists have used bright quasars as a sort of space clock, allowing them to measure time when the universe was much older than it is today. “Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower,” said Geraint Lewis from the University of Sydney, lead author on the new research. “If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.” Professor Lewis and other researchers gathered data from 200 quasars for the research. Quasars are very active supermassive black holes that sit in the middle of early galaxies, and hence provide a reliable way to look back at a much younger universe. Previous researchers have done the same using supernovae, or massive exploding stars. Those are useful but they are also difficult to see at the very very long distances of the early universe, meaning that the confirmation was limited only to about half the age of the cosmos. Now by using quasars scientists were able to look much further back, to just a tenth of the age of the universe, when it was only a billion years old. “Thanks to Einstein, we know that time and space are intertwined and, since the dawn of time in the singularity of the Big Bang, the universe has been expanding,” Professor Lewis said. “This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. “In this paper, we have established that back to about a billion years after the Big Bang.” The work is described in a new paper, ‘Detection of the cosmological time dilation of high-redshift quasars’, published in Nature Astronomy.

Days after the US Supreme Court struck down race-conscious university admissions, civil rights groups have filed a federal lawsuit targeting so-called “legacy” admissions at Harvard University. The lawsuit, alleging widespread discrimination at the college in violation of the Civil Rights Act, is the latest challenge to the practice of prioritising university admissions for the children of alumni. “There’s no birthright to Harvard. As the Supreme Court recently noted, ‘eliminating racial discrimination means eliminating all of it.’ There should be no way to identify who your parents are in the college application process,” said Ivan Espinoza-Madrigal, executive director of Boston-based Lawyers for Civil Rights, which filed the complaint on 3 July. “Why are we rewarding children for privileges and advantages accrued by prior generations?” he said in a statement. “Your family’s last name and the size of your bank account are not a measure of merit, and should have no bearing on the college admissions process.” The group filed the lawsuit on behalf of the Chica Project, the African Community Economic Development of New England and the Greater Boston Latino Network. Last week, the conservative supermajority on the nation’s highest court ruled that private and public colleges and universities may not consider race as a factor in admissions, striking down the precedent affirmed in the 2003 ruling in Grutter v Bollinger. Civil rights advocates and justices who supported the decades-long precedent, intended to promote racially diverse college campuses, derided what they argue is the court’s ongoing perversion of the 14th Amendment and the foundational concept of equal protection. The latest lawsuit points to Harvard data finding that 70 per cent of the college’s donor-related and legacy applicants are white. So-called “legacy” applicants have a roughly six times greater chance of admission, according to records, pointing to a “custom, pattern and practice” that is “exclusionary and discriminatory” and “severely disadvantages and harms applicants of color,” plaintiffs argued. The complaint calls on the US Department of Education to initiate a federal investigation into Harvard’s application process and for the federal government to declare such practices illegal. “Harvard’s practice of giving a leg-up to the children of wealthy donors and alumni – who have done nothing to deserve it – must end,” Lawyers for Civil Rights litigation fellow Michael Kippins said in a statement accompanying the complaint. Following the Supreme Court ruling, Democratic lawmakers and President Joe Biden urged universities to reconsider their legacy admissions, which he said “expand privilege instead of opportunity.” The Independent has requested comment from Harvard.

A huge phosphate rock deposit discovered in Norway contains enough minerals to meet the global demand for batteries and solar panels for the next 100 years, according to the mining company that controls it. Norge Mining said up to 70 billion tonnes of the non-renewable resource may have been uncovered in south-western Norway, alongside deposits of other strategic minerals like titanium and vanadium. Phosphate rock contains high concentrates of phosphorus, which is a key component for building green technologies but currently faces significant supply issues. Phosphorus was first discovered in 1669 by German scientist Hennig Brandt, who was searching for the philosopher’s stone. While it proved ineffective in turning ordinary metals into gold, it has become an essential component in lithium-iron phosphate batteries in electric cars, as well as for solar panels and computer chips. Russia previously controlled the world’s largest ultra-pure phosphate rock deposits, with the European Union warning that these “critical raw materials” have a high supply risk. The EU is currently almost entirely dependent on imports of phosphate rock from the rest of the world, according to a report from The Hague Centre for Strategic Studies, with China, Iraq and Syria also home to large deposits. The report, which was published before the discovery of the massive Norwegian deposit, warned that the EU should be “concerned about phosphate rock shortages”. An article in the scientific journal Nature last year warned of imminent supply disruptions of phosphorus, citing Russia’s invasion of Ukraine and the subsequent economic sanctions as a potential cause of market volatility. The global economy consumes an estimated 50 million tonnes of phosphorus each year, with scientists warning earlier this year that the planet could face a “phosphogeddon” if supply trends continue. “The buyers’ market is becoming increasingly crowded by limited trade – due to political instability in several source countries, as well as international sanctions imposed on others,” Norge Mining noted in a June blog post. “This is forcing importers to fear an impending crisis.” Norway’s Minister of Trade and Industry, Jan Christian Vestre, said last month that the government was considering fast-tracking a giant mine in Helleland once analysis is completed on 76 kilometres of drill cores. If approval is given, the first major mine could begin operation by 2028. The politician said Norway’s “obligation” was to develop “the world’s most sustainable mineral industry” following the discovery of the minerals. The mining plans already have the support of the European Raw Materials Alliance, according to local reports, while local consultations continue. A spokesperson for the European Commission described the discovery as “great news” for meeting the objectives of the Commission’s raw material objectives, with Norge Mining telling Euractiv that the projected 4,500-metre-deep ore body would theoretically be capable of meeting global demand for the next century.
