Five years ago, scientists managed to recreate what is known as superionic ice, in lab experiments for the first time. Superionic ice is believed to form within Uranus and Neptune as familiar materials are subjected to extreme pressures and heat, with iron atoms forming hot, black, heavy ice. But just last year researchers at several universities in the United States discovered a new phase of superionic ice. The discovery helps broaden our understanding of why Uranus and Neptune have off-kilter magnetic fields with multiple poles. Different to forms of water on Earth, the oxygen atoms in superionic ice are locked in a solid cubic lattice, while the ionised hydrogen atoms are loose, flowing through the lattice. This gives superionic ice conductive properties as well as raising its melting point, meaning the frozen water remains solid at temperatures up to 4704 Degree Celsius (8500 Fahrenheit). In this latest study, Stanford University's Arianna Gleason and colleagues blasted thin slivers of water, sandwiched between two diamond layers, with some extremely powerful lasers. "Recent discoveries of water-rich Neptune-like exoplanets require a more detailed understanding of the phase diagram of [water] at pressure–temperature conditions relevant to their planetary interiors," Gleason and colleagues explain in their paper, from January 2022 X-Ray diffraction revealed the hot, dense ice's crystal structure, and confirmed the ice crystals were in fact a new phase, distinct from the superionic ice that was observed in 2019. This newly discovered superionic ice, Ice XIX, has increased conductivity compared to its 2019 predecessor. The conductivity is important because it helps us understand why certain off-kilter magnetic fields are generated on planets such as Neptune and Uranus.

Electric car maker Tesla’s profits took a dive in the third quarter, according to an earnings call on Wednesday in which the company’s chief Elon Musk blamed staff working from home for being “detached from reality”. Tesla’s profits in Q3 of 2023 have plunged by over 40 per cent compared to the gains it made in the same period last year after the company slashed its car prices by around 25 per cent in an attempt to compete with other EV makers. The EV manufacturer reported a net profit of about $1.9bn for the time between July through September, which is a 44 percent drop from the $3.3bn it made in the same three-month period last year. While the company has seen a small increase in overall revenue of about $23bn from the $21bn the same time last year, the figures are still lower than Wall Street expectations. Mr Musk also dampened hopes of the company’s anticipated Cybertruck reviving profits in the near future, announcing that it would take at least 18 months for the truck to become profitable as it could go on sale only by the end of November. “There will be enormous challenges in reaching volume production with Cybertruck and making the Cybertruck cash flow positive,” the Tesla titan told investors and analysts in the earnings call. “The blood, sweat and tears that will be required to achieve that is just staggering,” he added. Over the last year, Tesla has slashed the prices of its cars by quarter to boost sales. Growing competition with the introduction of EVs by other car makers in the US, including BMW, Toyota, Mercedes, GM and Hyundai, has also coincided with Tesla’s share of vehicles in the EV market reducing in the last quarter. In the earnings call, Mr Musk also said staff working from home are taking advantage of those who cannot work from home. “Like... what about all the people that have to come to the factory and build the cars?” he asked. “Why did I sleep in the factory so many times? Because it mattered,” the Tesla chief said. Mr Musk echoed the statements he made in an interview with CNN earlier this year in which he called remote work “morally wrong”, arguing that it is unfair to those who cannot have the option. “Get off the goddamn moral high horse with the work-from-home bullshit,” he said. Tesla also pointed fingers at its reduction in production while it upgraded its factories as one of the factors behind the profit slump. It said it has also been making big investments in AI and “commissioned one of the world’s largest supercomputers.” “We have more than doubled the size of our AI training compute, accommodating for both our growing data set & Optimus, which is currently being trained for simple tasks through AI rather than hardcoded software, while its hardware continues to improve,” Tesla said. But all is not gloomy as the company says the first deliveries of its Cybertruck are scheduled for 30 November and Tesla’s Model Y remains the “best-selling vehicle of any kind” in Europe.

Amazon is testing whether humanoid robots that walk around with glowing eyes could help staff its warehouses. The company has in recent years added a host of new technologies as part of its Amazon Robotics arm, primarily using it in its warehouses, including arms and small carts that are able to help pack orders. It now has 750,000 robots working alongside employees, it said. This week it unveiled more of hose robots, including a system named Sequoia that helps pack its itinerary at those warehouses. But the most dramatic new robot was a system named Digit that is now being tested for Amazon’s operations. Amazon calls Digit a “mobile manipulator solution”, and pointed to the fact that they are able to move around and grasp items in ways that other robots aren’t. It does so in an uncannily human form, with glowing eyes in the front of its head and arms and legs that allow it to walk around. The system was built by Agility Robotics, which has a partnership with Amazon. It is 175cm tall, can work for 16 hours out of a day and has the ability to perceive people and crouch and squat, for instance. “Its size and shape are well suited for buildings that are designed for humans, and we believe that there is a big opportunity to scale a mobile manipulator solution, such as Digit, which can work collaboratively with employees,” Amazon said in an announcement. “Our initial use for this technology will be to help employees with tote recycling, a highly repetitive process of picking up and moving empty totes once inventory has been completely picked out of them.” Tye Brady, chief technologist at Amazon Robotics, said that he was more interested in how the humanoid form could allow for new kinds of mobility, such as using legs to walk over varied terrain, rather than having it mimic the look of humans. He also suggested that if the robot’s shape came to be a barrier to adoption then Amazon “can change that”. The robot is still in testing for now, in an attempt to understand how it might be used, and is not deployed in any of Amazon's normal operations. It may never actually be used, it suggested, if the project finds that such robots are not helpful. Amazon also committed to ensure “robotics are collaborative and support employees”. In an apparent attempt to allay concerns about the robots taking jobs and leaving its staff redundant, it pointed to the growth in new jobs that has come even as its investment in robotics has increased, and said that there were 700 new job categories that didn’t exist before that expansion. “From the hardware to the artificial intelligence embedded in our robotics, we are passionate about technology that makes the work experience of our employees safer, easier, and less repetitive,” Amazon committed. It said that the extra time saved with robots would allow employees to “take a step back” and evaluate how orders were being fulfilled, for instance. Amazon is just one of a range of companies looking at humanoid robots for logistical work. Tesla, for instance, has a system called “Optimus” which Elon Musk has suggested could eventually become its biggest business, but which is yet to actually be rolled out.
