The internet has been obsessed with Greta Gerwig’s Barbie for what seems like centuries now – but some people on social media have picked a rival team. Sindy was a British doll manufactured just four years later than her American counterpart. A little less glamorous and, perhaps, more realistic, Sindy still holds a place in the hearts of many in the UK. The toy even marks its 60th anniversary this year, after its original 1963 launch. Now, people are calling for the rivalry to get a reboot – and some even want a Sindy movie. Sign up to our free Indy100 weekly newsletter One Twitter user said: “There should simultaneously be a slightly less polished and expensive Sindy movie.” Another said: “Despite all the hullabaloo this weekend, I wish to re-pledge my loyalty and devotion to the one true queen, #TeamSindy.” One person referenced the filmmaker Ken Loach, whose work has often focused on social issues prevalent in working class Britain, adding: “Looking forward to the Ken Loach directed film about Sindy.” It comes as Barbie celebrates the biggest opening weekend for a film by a female director, grossing $162m over its first three days. The obsession with the American toy has spread far and wide with people dressing up for the occasion and queueing around the block in many places to get a look at the movie on the opening night. And as Barbie-mania shows few signs of abating, it looks like Sindy has a bit of catching up to do. Have your say in our news democracy.

A group of scientists and philosophers claim to have identified a “missing law of nature”, in a discovery which has huge implications for our understanding of how, basically, everything works. Most of us are familiar with the names – if not the intricacies – of many of the physical laws which govern the world and beyond, such as gravity and thermodynamics. And yet, no established physical law has been able to describe the behaviours of countless complex systems that exist across the universe – until now. In a paper published in the PNAS journal on 16 October, a multidisciplinary team from some of the US’s top institutes and universities, unveiled a new law claiming to do just that. In a nutshell, their law states that evolution is not limited to life on Earth, it also occurs in other massively complex systems – from planets to atoms. This means that these systems naturally “evolve” to states of greater diversity, and complexity. In other words, the researchers found evolution to be a common feature of the natural world's complex systems which, according to the Carnegie Institution for Science, comprise the following characteristics: “They are formed from many different components, such as atoms, molecules, or cells, that can be arranged and rearranged repeatedly “Are subject to natural processes that cause countless different configurations to be formed.” Only a small fraction of these configurations survive via a process of natural selection called “selection for function”. According to the researchers, regardless of whether the system is living or nonliving, when a new configuration works and function improves, evolution occurs. The authors' new law – which they have christened "the Law of Increasing Functional Information" – states that the system will evolve "if many different configurations of the system undergo selection for one or more functions." "An important component of this proposed natural law is the idea of 'selection for function,'" the study’s lead author, astrobiologist Dr Michael L. Wong, explained. The team’s research builds on Charles Darwin’s theory of natural selection, which suggests the function exists to ensure the “survival of the fittest”. For their work, Dr Wong and his team expanded on this perspective, pointing to the existence of three types of this selection for function in nature. The first, most basic type, they claim, is stability – the stable arrangements of atoms or molecules which are selected to continue. Second, are dynamic systems which are selected for their ongoing supplies of energy. And the third, and most intriguing, function is "novelty" – the tendency of evolving systems to explore new configurations which can lead to surprising new behaviours or characteristics. Novelties are, ironically, nothing new. Indeed, life’s evolutionary history is rich with examples: photosynthesis evolved when single cells learned to harness light energy; multicellular life evolved when cells learned to cooperate; and species evolved thanks to advantageous new behaviours such as walking and thinking. The same type of evolution happens in the mineral kingdom, as the Carnegie Institution for Science notes in a release published by Phys.org. Indeed, Earth's minerals, which began with about 20 at the dawn of our solar system, now number almost 6,000 known today. This is thanks to the ever more complex physical, chemical, and biological processes which have occurred over the past 4.5 billion years. The paper also notes that just two major elements – hydrogen and helium – formed the first stars shortly after the big bang. Those earliest stars then used this hydrogen and helium to create around 20 heavier chemical elements, which was built upon by the next generation of stars. "Charles Darwin eloquently articulated the way plants and animals evolve by natural selection, with many variations and traits of individuals and many different configurations," co-author and research lead Robert M. Hazen explained. "We contend that Darwinian theory is just a very special, very important case within a far larger natural phenomenon. “The notion that selection for function drives evolution applies equally to stars, atoms, minerals, and many other conceptually equivalent situations where many configurations are subjected to selective pressure." The new law has a number of exciting implications, including a deeper understanding of how the Universe itself came to exist. It could also help explain how life differs from other complex evolving systems, and could help aid the search for life elsewhere. Furthermore, at a time when increasingly autonomous AI systems are of increasing concern, it’s very handy to have a law that characterises how both natural and symbolic systems evolve. It also offers insights into how we could artificially influence the rate of evolution of some systems which, again, could prove invaluable. The key point to remember, as Dr Wong put it, is that whilst life is the “most striking example of evolution”, it’s not the only one. Evolution, it transpires, is everywhere.

The manhunt for convicted killer Danelo Cavalcante continues 12 days after his escape from Chester County Prison in Pennsylvania. The convict fled the facility days after he was sentenced to life for stabbing his ex-girlfriend Deborah Brandao, 33, to death. He is also wanted for a 2017 murder in Brazil. In an interview with The New York Times on Tuesday, Cavalcante’s mother Iracema Cavalcante defended her son’s actions, saying that he killed Brandao after she reportedly threatened to tell American authorities that he was being sought by Brazilian police. “Did it happen? It happened,” Ms Cavalcante told the Times. “But it happened because of the stranglehold she put on him, the stance she took with him ... It wasn’t femicide. He had to, he had no other choice.” In the latest update, Pennsylvania State Police said the search is now centred on South Coventry Township, warning locals that the fugitive is armed and that they should “lock all doors and windows”. At a press conference on Tuesday morning, Police confirmed that Cavalcante stole a .22 calibre rifle from a home in East Nantmeal Township on Monday, whose owner fired seven shots at him as he fled.
