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.

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.

Scientists have just created an entirely new state of matter made out of subatomic particles. The bosonic correlated insulator, to be precise, is both a new material and a new state of matter, said researchers from California, Arizona and Japan. There are four fundamental states of matter, liquid, solid, gas and plasma – an electrically charged gas found in situations like stars and lightning strikes. But there are many others when you drill down to quantum level (that means at an atomic and subatomic level). The scientists said this is a new one. Sign up to our free Indy100 weekly newsletter The new material is a lattice-shaped pattern, formed from a layer of the two different types of subatomic particles: bosons and fermions. Bosons are a type of particle which is difficult for scientists to create and manipulate because they do not interact with each other. Fermions are more stable – particles such as electrons – and interact through electrostatic force. The material sees the two different types of particle combining and interacting in a new way, with the particles eventually form into a crystalline state, which in turn creates a material which has an insulating effect. “Conventionally, people have spent most of their efforts to understand what happens when you put many fermions together,” says condensed matter physicist Chenhao Jin from the University of California, Santa Barbara (UCSB). “The main thrust of our work is that we basically made a new material out of interacting bosons.” The new material doesn’t yet have any practical uses, but exotic creations like this help scientists understand how the universe is put together, the team said. “What happened here is that we discovered the correlation that drove the bosons into a highly ordered state,” said physicist Richen Xiong, from UCSB. The scientists think the discovery could lead to them finding more materials like this further down the line. “We know that some materials have very bizarre properties,” said Xiong. “And one goal of condensed matter physics is to understand why they have these rich properties and find ways to make these behaviours come out more reliably.” Have your say in our news democracy.

The researcher who invented the term 'cisgender' has hit back at "cowardly" Elon Musk for calling the term a slur. 'Cis' or 'cisgender' was coined by now-retired researcher Dana Defosse. They are used to describe someone whose gender identity aligns with the sex they were assigned at birth. It is not offensive or intended to be used as an insult. Defosse first used the term in a 1994 internet forum, before being added to the Oxford English Dictionary much later in 2015. In an essay for HuffPost, Defosse explained how she invented the term: "I knew that in chemistry, molecules with atoms grouped on the same side are labelled with the Latin prefix ‘cis–,’ while molecules with atoms grouped on opposite sides are referred to as ‘trans–.’ So, cisgender. It seemed like a no-brainer," she wrote. On Wednesday (21 June), Musk responded to a user who claimed to have been harassed by trans rights activists. Twitter user James Esses said he "rejected" the terms after receiving "a slew of messages from trans activists calling me ‘cissy’ and telling me that I am ‘cis’ ‘whether or not I like it.’" In response, Musk tweeted: "Repeated, targeted harassment against any account will cause the harassing accounts to receive, at minimum, temporary suspensions. The words “cis” or “cisgender” are considered slurs on this platform." Sign up for our free Indy100 weekly newsletter The tech mogul's response left many social media users baffled, with Defosse saying it came as no surprise after his "ghastly history of attacking trans people." “The post on Twitter has degenerated into a sort of free-for-all for antisemitic and racist tropes, so it sort of fits in with the direction that platform is going," Defosse said. "The fact is, whether or not somebody identifies as cisgender doesn’t negate the fact that cisgender identity is a valid construct. It exists, and it has meaning in how we operate in the world." The retired researcher went on to call his censorship attempt "cowardly". "Banning use of a word that’s part of our daily vocabulary around the world, that appears in the Oxford English Dictionary, it’s a cowardly and futile attempt to censor an idea which is, in my opinion, way bigger and more enduring than anything Musk could hope to offer," she added.
