A Nasa scientist has said chemicals found on Mars would be considered signs of ancient life if they were found on Earth, leading to suggestions the Red Planet could potentially have harboured life. Dr Michelle Thaller said: “On Mars we see chemistry that on Earth, if it were here, we would say is due to life. “But the question is, how well do we understand Mars and are we being fooled by something?” It’s not a done deal, of course. Signs of ancient life that we find regularly on Earth may not mean the same thing elsewhere, particularly with the vastly different conditions between the two planets. Dr Thaller told The Sun she is certain there is life out there in our solar system, but did not reveal the exact chemical substance that had been found. Nasa has previously found methane on Mars, which it said “could have supported ancient life”, and the organisation has also revealed plans to look for amino acids that haven’t yet been destroyed by space radiation. Organic chemicals like amino acids are used by archaeologists to determine whether life was present. A blog post from the US space agency said: “Amino acids can be created by life and by non-biological chemistry. “However, finding certain amino acids on Mars would be considered a potential sign of ancient Martian life because they are widely used by terrestrial life as a component to build proteins. “Proteins are essential to life as they are used to make enzymes which speed up or regulate chemical reactions and to make structures.” Alexander Pavlov of Nasa’s Goddard Space Flight Center in Greenbelt, Maryland, added: “Our results suggest that amino acids are destroyed by cosmic rays in the Martian surface rocks and regolith at much faster rates than previously thought. “Current Mars rover missions drill down to about two inches (around five centimeters). “At those depths, it would take only 20 million years to destroy amino acids completely.” That may sound like a long time, but Nasa is looking for life that is billions of years old, because scientists think Mars would have been more like Earth back then. Dr Thaller said it was important not to actually say there were signs of life until there is 100 per cent confirmation. “The solar system may be teeming with simple life, microbial life. “We just have to get that 100% certainty to say that we found it and we don’t have that yet.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

TEMPE, Ariz.--(BUSINESS WIRE)--Jul 16, 2023--

Donald Trump is widely expected to be indicted imminently by Justice Department special counsel Jack Smith over his efforts to overturn the 2020 US presidential election result and his role in inciting the Capitol riot of 6 January 2021. Should that happen and he is brought to trial in Washington DC, Mr Trump would appear before a judge selected at random to oversee the case in accordance with the local rules. However, since he was the 45th president of the United States, Mr Trump stands a one-in-three chance of coming up against a jurist he personally appointed. Four of the 12 district judges currently active in DC – Judges Timothy Kelly, Trevor McFadden, Dabney Friedrich and Carl Nichols – were elevated to their current positions during the Republican’s four years in the White House between 2017 and 2021, meaning, at least at that point, he believed them to be politically sympathetic to his own values. Both Judge McFadden and Judge Nichols have raised eyebrows since then through their handling of January 6 defendants, the former delivering the only acquittal in a bench trial resulting from the failed insurrection and attempting to waive grand jury secrecy in court and the latter finding himself in disagreement with no fewer than 10 of his peers when he ruled that the Justice Department could not charge the accused rioters with obstruction of an official. The remaining eight active justices were appointed by either Barack Obama or Joe Biden, which, following the same logic, suggests they are likely to have more Democratic leanings. The ranks of DC’s senior judges, meanwhile, include veterans appointed during the Ronald Reagan, Bill Clinton and George W Bush administrations, two of whom – Emmet Sullivan and Amy Berman Jackson – have a recent track record of making enemies of Trumpworld luminaries. Judge Sullivan told Mr Trump’s short-lived first national security adviser Michael Flynn in 2018 that might have been charged with “treason” over his undeclared lobbying on behalf of the Turkish government, drawing the ire of the MAGA movement, while Judge Jackson attracted headlines when she issued a gag order against self-styled Republican political fixer Roger Stone after he posted a picture of her on Instagram with a rifle’s crosshairs zeroing in on her forehead. As for DC’s juror pool, citizens of the nation’s capital have distinguished themselves in recent years through their careful and considered handling of January 6 cases, despite voting overwhelmingly for Mr Biden at the ballot box and witnessing the violence of that ignominious day first-hand on their own doorsteps. For all that, Brandon Van Grack, a former federal prosecutor who worked on special counsel Robert Mueller’s investigation into Mr Trump’s alleged ties to Russian election meddling in 2016, argues that too much emphasis is placed on a justice’s supposed political affiliations, especially among the conspiracy-minded. “There are so many exceptions to it,” he told The Messenger. “I think it’s just too much shorthand for people who don’t know the court and who don’t know the judges.” Read More Trump news – live: Trump and aides charged with plotting to delete security footage in classified docs case Trump slams Jack Smith’s superseding indictment in classified docs case as ‘election interference’ Trump’s election fraud claims were always bogus.

He was the king of the intelligent interview.” The director-general of the BBC paid tribute to Sir Michael Parkinson as “the king of the chat show” and an “incredible broadcaster and journalist”. In a statement, Tim Davie said: “Michael was the king of the chat show and he defined the format for all the presenters and shows that followed. “He interviewed the biggest stars of the 20th century and did so in a way that enthralled the public.
