Scientists have developed a simple test in the search for alien life, they claim. The breakthrough helps the search for the “holy grail” of astrobiology: a reliable test that will determine whether there is or was life on other planets. The discovery uses artificial intelligence to determine with 90 per cent accuracy whether a sample is biological or not. And it could be used on existing samples, researchers say. That might mean, for instance, that we already have gathered the samples that could tell us whether there is life on Mars. Scientists hope that their test could be used on samples already collected by the Mars Curiosity rover’s Sample Analysis at Mars (SAM) instrument. The rover has an instrument on board to analyse those samples, and that data could be used in the test. The findings could also help tell us more about our own planet, revealing the history of mysterious and ancient rocks found on Earth. “The search for extraterrestrial life remains one of the most tantalizing endeavors in modern science,” said lead author Jim Cleaves of the Earth and Planets Laboratory, Carnegie Institution for Science, Washington, DC. “The implications of this new research are many, but there are three big takeaways: First, at some deep level, biochemistry differs from abiotic organic chemistry; second, we can look at Mars and ancient Earth samples to tell if they were once alive; and third, it is likely this new method could distinguish alternative biospheres from those of Earth, with significant implications for future astrobiology missions.” The technique does not look for specific molecules or compounds that could be indicative of life, as much previous work has done. Instead, it looks for small differences in the molecular patterns of samples using different kinds of analysis. It was built by giving an artificial intelligent system data about 134 known samples, with information about whether they are biotic or abiotic. To test it, it was then given new samples – including those from living things, remnants of ancient life and other abiotic samples that did not point to life, such as pure chemicals – and identified them with 90 per cent accuracy. The system also started predicting another kind of sample type, dividing the biotic ones into “living” and “fossils”. That means it could tell the difference between a freshly harvested leaf and something else that died long ago, for instance. Scientists hope that with time it could eventually be able to distinguish other hints in the data, such as signs of photosynthesis or cells that have a nucleus. Previous research has struggled because organic molecules tend t degrade over time. But the new method works even when the samples have decayed and changed significantly, the researchers behind it said. “This routine analytical method has the potential to revolutionize the search for extraterrestrial life and deepen our understanding of both the origin and chemistry of the earliest life on Earth,” said Robert Hazen, of the Carnegie Institution for Science, one of the leaders of the research. “It opens the way to using smart sensors on robotic spacecraft, landers and rovers to search for signs of life before the samples return to Earth.” The findings could also help solve mysteries on life. Many ancient rocks on Earth are at the middle of argument over whether they hold the oldest fossil microbes in life, while others say they do not have any life – and researchers are already feeding data about those rocks from Australia, Canada and elsewhere into the tool. “We’re applying our methods right now to address these long-standing questions about the biogenicity of the organic material in these rocks,” Hazen says. A paper describing the work, ‘A robust, agnostic biosignature based on machine learning’, is published in the Proceedings of the National Academy of Sciences.

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."

"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.

Millions of people fly on airplanes each year, so it's easy to imagine how germs and bacteria can grow in certain places - and why passengers bring anti-bacterial wipes with them. Now, one Master of Science student (@The_lab_life1) decided to see for herself by swabbing different areas of the airplane - and the results are interesting. As part of her TikTok series "What Will Grow?" the TikToker boarded a flight and then filmed herself swabbing a head rest, a tray table, the bathroom lock and handle. Sign up to our free Indy100 weekly newsletter (With safety gloves on, of course). She then brought those swab samples back to the lab where she had to "make a lawn" as she swiped each of the samples across different petri dishes and then stored them away to wait for the results. After an undisclosed amount of time, the TikToker got the petri dishes out to see what happened to them. First up, the head rest sample had white spots all around it, as it contained: "M. luteus," "Streptococcus sp." and "N.subflava," as well as "M.Smegmatis." @the_lab_life1 Much better than expected, all pretty normal flora bacteria ?? #fyp #science #lab #whatwillgrow While the tray table sample had some tiny spots along with lighter shapes around the edges, and listed it as "B.subtilis," and bathroom lock and handle had yellow and white spots in it's petri dish also, which turned out to be "M. luteus," "Staphylococcus sp." and "Streptococcus sp." In the caption, the scientist gave her verdict: "Much better than expected, all pretty normal flora bacteria." The video has since gone viral with 1.3m views as people left their thoughts in the comment section. One person wrote: "Be right back, need to go wash my hair …. Again." Though when another asked if this was all bad bacteria, the TikTok replied: "No actually most of it is very normal and not harmful!" Someone else questioned: "How scared did that make the people sitting next you?" To which she replied: "I waited till they were asleep, didn’t wanna freak them out." Others made their fear of bacteria and germs known after watching the video. "This is why I bring my wipes everywhere better than nothing," one person said. Another wrote: "This made me not wanna ever go on an airplane." "I will never be embarrassed about wiping down my area on the flight ever again," someone else commented.
