An Australian cyber regulator on Thursday said it has demanded Twitter explain its handling of online hate as the microblog has become the country's most complained-about platform since new owner Elon Musk lifted bans on a reported 62,000 accounts.

Three US senators are pressing Facebook-parent Meta, Google-parent Alphabet and Twitter about whether their layoffs may have hindered the companies' ability to fight the spread of misinformation ahead of the 2024 elections.

Microsoft has announced plans to build a quantum supercomputer after researchers said the next-generation machines will be able to outperform standard computers within the next two years. Quantum computers have the potential to be orders of magnitude more powerful than today’s leading supercomputers, but have so far failed to compete when it comes to practical tasks. A recent benchmark experiment from quantum computing researchers at IBM suggests that the machines will soon be able to perform useful calculations “at a scale where classical computers will struggle”, opening up a vast number of applications. “These machines are coming,” Sabrina Maniscalco, chief executive of quantum computing startup Algorithmiq, told the scientific journal Nature which published the research this month. Microsoft revealed its roadmap for building its first “quantum supercomputer” on Wednesday, following several years of research and hundreds of millions of dollars of investment into the technology. Quantum computers work by replacing traditional bits – the ‘ones’ and ‘zeros’ used to store and transfer digital data – with quantum bits, called qubits, that make use of a quantum phenomena known as superposition to exist in two states at once. This means they can serve as both a ‘one’ and a ‘zero’ simultaneously, so that each qubit added makes them exponentially more powerful than their traditional counterparts. Microsoft said it made its own breakthrough by engineering a new type of qubit, described in the journal Physical Review B on Wednesday, that is stable enough to work at scale on a quantum supercomputer. Microsoft describes a quantum supercomputer as one that can perform one million quantum operations per second, claiming its construction will be completed within the next decade. “Microsoft has achieved the first milestone towards creating a reliable and practical quantum supercomputer,” the firm wrote in a blog post detailing the roadmap. “Today marks an important moment on our path to engineering a quantum supercomputer and ultimately empowering scientists to solve many of the hardest problems facing our planet.” Microsoft CEO Satya Nadella said it was his company’s goal “to compress the next 250 years of chemistry and materials science into the next 25.” The announcements from IBM and Microsoft follow several major quantum computing breakthroughs in recent years. In 2019, scientists at Google announced that they had achieved something known as quantum supremacy, when their Sycamore quantum computer was able to solve a problem in 200 seconds that would have taken the most powerful supercomputer in the world 10,000 years to solve. The milestone has since been repeated by researchers in China, whose quantum computer is able to perform computations nearly 100 trillion times faster than the world’s most powerful supercomputer. While impressive, neither the Chinese machine nor Google’s Sycamore had any practical use. John Martinis, one of the Google researchers behind the 2019 milestone, said the latest news made him “optimistic that this will work in other systems and more complicated algorithms”.

One of the key building blocks required for human life has been found in the depths of space. Astronomers have been looking out into a region 1,000 light-years from Earth, known as the Perseus Molecular Complex, and they’ve found an amino acid which is essential in human growth. Tryptophan is one of the 20 amino acids required for humans to develop. Babies require it to grow and it’s also important for protein development and muscle function in adults Readings from the Spitzer telescope, which is no longer in use, were crucial to the discovery. Sign up to our free Indy100 weekly newsletter The Perseus Molecular Complex is only visible when viewed through infrared instruments, and tryptophan gives off an identifiable light reading when observed in this way. Dr Susana Iglesias-Groth is from the Instituto de Astrofísica de Canarias and was lead author on the new research. "The evidence for tryptophan in the Perseus molecular complex should encourage additional effort to identify other amino acids in this region, and in other star-forming regions,” Dr Iglesias-Groth said. “It is a very exciting possibility that the building blocks of proteins are widely present in the gas from which stars and planets form – it may be key for the development of life in exoplanetary systems.” The findings were published in the Monthly Notices of the Royal Astronomical Society. It comes after research showed that life forms could potentially be able to survive in the conditions in the clouds above Venus. The key point revolves around the presence of the biosignature gas phosphine, which is often identified as a sign of life. It also posits the idea that potential life forms on the planet could use sulphuric acid the way life forms on Earth use water. Have your say in our news democracy.
