The Earth is home to truly stunning natural features, but sometimes you need a new perspective to appreciate it all over again. Thankfully, the experts at NASA are on hand to remind us just how incredible our planet is with the release of new photos showing the “blood of Earth”. The incredible images seem to show it bleeding, with dramatic red liquid appearing to cascade over the surface. However, it’s nothing at all to do with blood – which is probably just as well. Instead, the first picture shows the Laguna Colorada in the Bolivian Andes in South America from space. Remarkably, the image was taken by an astronaut onboard the International Space Station (ISS) using just a Nikon digital camera. The fact that it was taken more than 400 kilometres away from Earth on a handheld device is pretty staggering, and it offers a look at a natural phenomenon which we’d never otherwise get to see. The first picture shows the impact of red algae flourishing in the shallow water of the laguna, while the second shows the Betsiboka River Delta in Madagascar. This time, the red colour comes as a result of the iron-rich sediment. It’s pretty awe-inspiring stuff, and it’s not the first time that red “blood” has been seen running from our planet, either. Antarctica’s Blood Falls is a bizarre geographical feature in the McMurdo Dry Valleys region of the continent, and it’s one of the strangest natural phenomena you're likely to see. It features a flow of water the colour of blood that can be seen seeping out from a glacier into the ocean. The mystery behind it has fascinated members of the scientific community for decades, but a solution has now been found.

Elon Musk has launched a new AI company that aims to “understand reality” and unlock the secrets of the universe. The formation of xAI brings together researchers from leading artificial intelligence firms, including Google’s DeepMind, OpenAI and Microsoft Research, who collectively have contributed to major advances in AI in recent years. Announcing the launch on Twitter on Wednesday, Mr Musk gave further details about what he hoped to achieve with his latest venture. “I often wonder where consciousness starts, as we progress from one cell to ~35 trillion cells,” Mr Musk wrote. “If the Standard Model is correct, then quarks and leptons become ‘conscious’ no later than ~13.8B years from start, assuming there are no sentient aliens. Btw, where are the aliens!?” Mr Musk has warned for months about AI’s potential for “civilizational destruction,” arguing that a race among companies such as Google and Microsoft to develop the technology should be halted to allow time for drafting regulation for the sector. The reason for the launch of xAI is “to understand the true nature of the universe,” said Mr Musk, who also co-founded OpenAI but later left the startup credited with sparking the generative AI frenzy through its launch of the ChatGPT chatbot. Dan Hendrycks, who serves as the director of the Center for AI Safety, a nonprofit that aims to reduce the risks posed by the technology, will be an adviser to xAI. The startup’s team includes several former engineers and scientists from Alphabet-owned Google, Microsoft and OpenAI. “We have worked on and led the development of some of the largest breakthroughs in the field including AlphaStar ... GPT-3.5, and GPT-4,” the startup said on its website. The company, which is looking for experienced engineers and researchers to join its team as technical staff in the Bay Area, will hold a Twitter Spaces event on 14 July. Mr Musk’s startup will work closely with his other companies including Twitter and Tesla, according to the website. Tesla shares showed little reaction to the news and were trading 1.5 per cent higher, a sign that investors were not worried the startup will be a potential distraction for Mr Musk. The billionaire in March registered a firm named X.AI Corp, incorporated in Nevada, according to a state filing. The firm lists Musk as the sole director and Jared Birchall, the managing director of Musk’s family office, as a secretary. Mr Musk has previously warned of the existential risk posed by advanced AI, claiming that it is one of the most serious threats to the future of humanity. Earlier this year, he joined more than 1,000 tech leaders and researchers in signing an open letter urging a moratorium on the development of powerful AI.
