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.

Young adults who snore at night have a significantly higher risk of having a stroke and developing heart disease when they get older, a study has warned. Doctors have said that snoring should be treated as a “red flag” among adults below the age of 50. The study found that young adults who snore are 60 per cent more likely to develop a stroke when they reach middle age, and five times more likely to develop a heart rhythm disorder. The researchers presented their findings at the European Society of Cardiology Congress in Amsterdam. They examined data from 766,000 US adults aged 20 to 50. These included 7,500 adults with obstructive sleep apnoea, a condition that causes interruptions to normal breathing during sleep. This can lead to loud snoring and interrupted sleep as sufferers wake up while struggling to breathe. The study found that, over the 10-year follow-up period, patients with sleep apnoea were 60 per cent more likely to suffer a stroke compared to those who did not snore as frequently. They were also five times more likely to develop atrial fibrillation, a heart condition that causes irregular and often abnormally fast heart rate. Symptoms of atrial fibrillation include heart palpitations, dizziness and shortness of breath. Lead author Professor Sanjiv Narayan, of Stanford University, said: “Sleep apnoea is really common but we sort of ignore it because we think it’s trivial or just a little bit of a nuisance. “Until now no one’s really shown the magnitude of the size of the risk for heart diseases. That’s what really surprised us.” He added that the study looked at “relatively young people” who may not know they are at risk. “If they had a stroke, it would devastate young families. It could take them away from their workplace. It would destroy their lives for the next 40 years.” The researchers suggest that GPs should ask patients regularly if they snore and highlight if as a heart health “red flag” that could show they need more tests or medication. Obstructive sleep apnoea is fairly common and is estimated to affect 1.5m adults in the UK. However, according to the British Lung Foundation, up to 85 per cent of sufferers are undiagnosed and go untreated. Men who are elderly and overweight are particularly prone to sleep apnoea. Interruptions to normal breathing can cause a dip in blood oxygen and cause the heart and blood vessels to strain. Prof Narayan explained: “When you are unable to breathe it raises the pressure in the lungs until you ultimately wake up gasping for breath. That puts a pressure load on the heart, which causes stretch in the heart chambers, and that could cause the atrial fibrillation. “Another theory could be that the oxygen levels in the blood fall for tens of seconds and that could put stress on the heart.” Sleep apnoea can be treated using a CPAP machine, a device that pumps air into a mask that the patient wears over their mouth or nose while they sleep. The NHS also recommends making lifestyle changes such as losing weight if the patient is overweight and exercising regularly, which can improve symptoms. Sleeping on your side may also help relieve sleep apnoea.
