Fire might seem like one of the most elemental things in the natural world, but it’s never been found anywhere other than Earth. It’s because the creation of fire relies on very specific circumstances. In fact, if fire was ever found on another planet, it would be a good indicator of the possible existence of life. Oxygen is key to fire, and while it’s particularly prevalent in the universe, Earth’s atmosphere features an abundance of the element in the right molecular form for it to form. Even then, the way the Earth’s atmosphere has changed over its lifespan is also crucial to conditions being fostered where fire can form [via IFLScience]. For millions of years, in fact, there wasn’t enough oxygen in the atmosphere to create fire. Before the Middle Ordovician period, when there was far less oxygen, there’s no evidence of fire whatsoever. Most of the fuel that fire needs is also directly related to life existing on the planet – think wood, oil and coal. Without life, there isn’t an awful lot of fuel going around, which just shows why the existence of fire on another planet would be a very promising sign when it comes to exploring the universe for life. Despite fire being much rarer in the universe than most might think, it was previously confirmed that humans in Europe may have mastered fire long before we previously thought. According to a study published in Scientific Reports, humans made the discovery around 245,000 years ago, up to 50,000 years earlier than scientists believed, Researchers studied samples from the Valdocarros II, a huge archaeological site found east of Madrid, Spain. Using chemical analysis, they found certain compounds that show things were burnt by fire in "organised" social events, rather than through accidents or wildfires.

Apple has revealed the iPhone 15 and 15 Plus, its new cheaper phones. The new handsets borrow a host of features from last year’s more expensive, Pro models. It gets the “Dynamic Island” at the top of the screen, its predecessor’s processor, and upgraded cameras. But it packs that into a cheaper and brighter design. Apple said it is the first time that anyone has made the colour run all the way through the glass, and that it has used “metallic ions” to build colour into the material itself. It comes in five different colours: pink, yellow, green, blue and black. The design is changed ever so slightly, too. Apple said that it should feel “even nicer in your hand” because of a “new contoured edge” on the side of the phone. But the main upgrades from the iPhone 14 appeared to be in the camera. That will now be 48 megapixels – compared with 12 in the previous model – and new machine learning tools that will improve those pictures. The iPhone 15 also comes with a new ultra-wide band chip for finding other devices. That can be used to find other people: using the Find My app, the phone will show precise directions for finding people in busy places, for instance. Phone calls are also due to improve, Apple said. That should filter out distracting noises from the background to make them clearer. That was part of a host of connectivity improvements, which also added new features to Apple’s satellite features. If drivers have trouble with their car, they can use that extra satellite connectivity to get in touch with roadside service, for instance.
