Minuscule traces of metal from space junk that's designed to be disposable are invisibly polluting the Earth's atmosphere, a new study has found. In recent times, spacecrafts launched into space have been designed so that they fall out of orbit and fall back down to Earth after their intended use. So instead of the materials crashing on land, they can burn up in the upper atmosphere. Although the debris of rockets and satellites burn up when re-entering the planet's atmosphere, the consequences of metal vapour being left behind currently remain unknown. But given the amount of space exploration taking place, the amount of metal vapour is expected to rise in the years to come. Physicist Daniel Murphy of the National Oceanic and Atmospheric Administration (NOAA) has led a team of researchers to investigate what effects this metal vapour could have as well as its impact over time and this study was published in Proceedings of the National Academy of Sciences, as per Science Alert. He listed "iron, silicon, and magnesium from the natural meteoric source" as the current refractory material in stratospheric particular. Murphy has warned how this composition could be affected by the metal vapour from space junk. "However, the amount of material from the reentry of upper-stage rockets and satellites is projected to increase dramatically in the next 10 to 30 years," he wrote. "As a result, the amount of aluminum in stratospheric sulfuric acid particles is expected to become comparable to or even exceed the amount of meteoric iron, with unknown consequences for inclusions and ice nucleation." To find out if metal vapour remained, Murphy and his team took and analyzed 500,000 stratospheric aerosol droplet samples to see if they had traces of spacecraft metals. Aerosols contain sulfuric acid droplets made from the oxidation of the carbonyl sulfide gas and in the atmosphere, this can appear naturally or as a pollutant. Metal and silicon traces can be found in these droplets too, acquired from meteors which vaporize upon atmospheric entry. Around 20 metals were discovered from this research, and while some metals had similar ratios to the vaporizing meteors, other metals such as lithium, aluminium, copper, and lead exceeded the anticipated amounts. Particles from vaporized spacecraft were found in 10 per cent of stratospheric aerosols over a certain size while other common spacecraft metals such as niobium and hafnium were also present. Consequently, these traces of spacecraft particles could affect how water freezes into ice in the stratosphere, and stratospheric aerosol particles could change in size. Due to more space exploration planned in an "era of rapid growth" for the industry, the researchers predict "the percentage of stratospheric sulfuric acid particles that contain aluminum and other metals from satellite reentry will be comparable to the roughly 50 per cent that now contain meteoric metals."

Just 22 minutes of housework, jogging or brisk walking per day could offset the negative effects of sitting down for too long, new research has suggested. Researchers found sitting for extended periods – for example, long stints in front of the TV or working at a desk – is associated with dying earlier. However, participating in moderate-to-vigorous physical activity (MVPA) can eliminate the risk. At the more moderate end of the scale, this could be anything from heavy cleaning around the home, playing badminton or cycling at 10-12mph, while more vigorous activities could include jogging at 6mph or faster, playing football, basketball or tennis. The study, published online in the British Journal of Sports Medicine, backs up the UK chief medical officers’ recommendation of trying to get 150 minutes of MVPA per week – roughly 21 minutes per day. The research looked at data for 11,989 people aged over 50, half of whom where women, from Norway, Sweden and the US, who had worn activity trackers which measured their MPVA. How long they spent sitting daily was also recorded. Over a five-year follow-up, 805 of the people died. Author Edvard Sagelv, from the Arctic University of Norway, told the PA news agency: “In our study, we found that only those people doing more than 12 hours per day sitting had a higher risk of death. Every minute higher MVPA showed a lower risk of death – meaning if people were doing less than 22 minutes (such as 10 minutes) there was still a lower risk of death. “However, doing 22 minutes eliminated the higher risk of death from sedentary time. This means that if doing 22 minutes or more per day, there was no excess risk from sedentary time. And, if doing more than 22 minutes per day, there was a lower risk of death overall. Basically, the more the better.” How can I get the best workout in 22 minutes? Less than half an hour a day to offset the negative effects of sitting for too long is good news for anyone who normally struggles to find time to exercise – but how can you make those 22 minutes really count? We asked a fitness pro for some suggestions… Compound exercises Ali Malik, personal trainer and founder of Fit Labs Kensington, suggested focusing on compound exercises. “Compound exercises are full-body exercises that engage with multiple muscle groups at the same time. When you are limited in time, it would be more beneficial to do a squat, for example, which engages your core, lumber spin and whole lower body, instead of a bicep curl, which doesn’t,” Malik said. “Push-ups are also great, as they engage your upper body muscles and core. If you are doing it on your knees, you use less of your legs, but a full push-up will be using your glutes and legs as well – engaging with more than one muscle group.” Planks are another great compound exercise, because “it’s predominately about your core but engages your full body, as you have to work hard to keep yourself stabilised”. Malik added: “People sometimes think dead lifts is an advanced exercise, but it’s not. Everyone does a does at least one everyday. For example, if you are picking up a bag from the floor, that’s a dead lift. It can be done with anything as light as two plastic bags filled with a water bottle each, but if you are in the gym you can use dumb bells and kettle bells.” Circuits For a well-rounded workout in 22 minutes, Malik also suggested a circuit based workout – starting with a three-minute warm-up. “This could include a cat cow stretch, a walk out [start standing up, then bend forwards and walk your body out in front of you using your hands, and then back up to standing], then jumping jacks to get your heart rate up and loosen your muscles.” Then for the circuits, it’s all about repeating multiple exercises in the same order. “I would do 10 squats, 10 press-ups and a 30-second plank. Then rest for 30 seconds, and then repeat that pattern six times. This is about 16 minutes of the workout,” said Malik. “But if you are feeling bored and would like to switch things up, you could do 10 lunges, 10 shoulder taps and leg raises instead.” Being efficient during a short workout is key, added Malik: “You don’t want to rush through the exercises to risk poor form, but you also don’t want to waste time with long five minute breaks.” Allow for a three-minute cool-down at the end. Malik explained: “It’s all about calming movements at this stage, to bring down your heart rate and relax your muscles. Start with a child pose, striking cobra – push your pelvis into the floor and then raise your chest, whilst applying pressure with both hands on either side of the body – then I would do a pigeon pose, where you have one leg out in front of you in a bent position and one leg behind you that is straight. This stretches your glute muscles.” What are the benefits? There are various benefits to exercises using this format. Malik said: “It will elevate your heart rate, put your muscles under tension to maintain and build strength, and help with your cardiovascular system.” Read More What crops will we be growing in the future, as climate change alters the landscape?

When is the squad submission date for the 2023/24 Premier League?

Max Verstappen has criticised the “99% show, 1% sporting event” nature of this weekend’s inaugural Las Vegas Grand Prix and lambasted Wednesday’s opening ceremony. F1 is returning to Vegas for the first time in more than 40 years with a new street circuit, with F1 themselves promoting the event and building a new pit building to the tune of $500m. But three-time world champion Verstappen, who was among the 20 drivers dramatically introduced to the crowd during Wednesday’s lavish opening ceremony via a lift onto a string of podiums, did not pull any punches about the spectacle of the event in Sin City. “I don’t like all the things around it,” said the Red Bull driver. “I’m looking forward to trying to do the best I can but I’m not looking forward to this. “For me you can skip these kind of things. It’s just standing up there, you look like a clown. “I fully understand and you can look at it two ways, business side or sport side. So, of course, I understand their side of it. “I’m just voicing my opinion on the performance side of things.” Wednesday’s opening ceremony started with spectacular drone sequences, preceding a number of performances from artists such as Kylie Minogue, John Legend and Tiesto. All 20 drivers then briefly appeared to rapturous applause from the crowd in the grandstands.

Donald Trump has already been indicted three times this year, twice at the federal level. In April, he was arraigned in New York and pleaded not guilty to state charges after receiving an indictment from Manhattan district attorney Alvin Bragg accusing him of manipulating his business records to conceal hush money payments allegedly made to porn actress Stormy Daniels in 2016 to stop her discussing an extramarital affair they are said to have had in 2006 in time to derail his presidential run. Justice Department special counsel Jack Smith then handed him a federal indictment in May over his alleged mishandling of classified government documents following the conclusion of his one-term presidency and then another in August over his efforts to overturn the 2020 election result, accusing him of conspiracy to defraud the United States, tampering with a witness and conspiracy against the rights of citizens. In both cases, Mr Trump again pleaded not guilty to all charges. But that’s not all. He could be about to face a fourth indictment, this time from Fani Willis, district attorney of Fulton County, Georgia, over his attempts to influence the 2020 vote count in that crucial swing state, which turned blue for Joe Biden and prompted Mr Trump to pressure local secretary of state Brad Raffensperger into helping him “find” the 11,780 ballots he needed to win, a conversation that was recorded and described as “worse than Watergate” by veteran Washington Post journalist Carl Bernstein. While Ms Willis hasn’t confirmed that an indictment will be handed down this week, her earlier statements and security measures surrounding the Fulton County courthouse indicate that movement is imminent in the case. No former or sitting president of the United States has ever been formally charged with a crime before, so for Mr Trump to have received multiple indictments is already history-making, another ignominious claim to fame for the first American commander-in-chief ever to have been impeached twice. The prospect of Mr Trump winning the presidency again in November 2024 and then attempting to use his presidential pardoning powers to excuse himself is a fascinating prospect that could yet become a reality. As president between 2017 and 2021, Mr Trump cheerily used his executive clemency powers to hand out pardons to no fewer than 237 people, from Arizona sheriff Joe Arpaio to right-wing content creator Dinesh D’Souza by way of cronies like Steve Bannon, Roger Stone, Michael Flynn, Paul Manafort and George Papadopoulos. Whether he had the authority to pardon himself was a key question at the time he left office in the aftermath of the deadly Capitol riot of 6 January 2021, which, ultimately, never had to be answered because he did not attempt to do so. The broad consensus among legal experts back then was that there was no stipulation in place to actually prohibit such an act but, given that there was no precedent for it either, it would likely be subjected to a lawsuit calling into question its legal validity. While Mr Trump is now a private citizen and therefore has no such powers, he does find himself in the extraordinary position of being thrice-indicted while simultaneously leading the pack for the Republican Party’s nomination to be its candidate for president in 2024, leaving such rivals as Ron DeSantis, Mike Pence, Nikki Haley, Tim Scott and Chris Christie eating his dust in the polls. There is nothing in the US Constitution to stop someone from running a presidential campaign while under indictment or even having been convicted of a crime, although its 14th Amendment does prevent anyone from running who has taken an oath of office and thereafter engaged in “insurrection or rebellion” against the country, which could ultimately cause problems for Mr Trump should he be convicted over Mr Smith’s charges pertaining to the Capitol riot. Unless that comes to pass, however, he is free to run for the White House once more. But what would happen if he were to actually win and attempt to use his reinstated pardoning powers for his own benefit is where matters get really knotty. Firstly, presidential pardons are only applicable to federal crimes. While that means he could potentially absolve himself in the classified documents and 2020 election cases brought by Mr Smith, he could not do the same in the indictment brought by Mr Bragg, which is a state affair. Second, the Constitution bans presidents from pardoning themselves from impeachments, meaning any conduct Mr Trump is found guilty of committing in connection with impeachment would not be eligible for a pardon. Third, any pardon would almost certainly result in a Supreme Court case and the court might not be inclined to side with Mr Trump, despite the current conservative majority on its benches. A Justice Department memo from 1974 stated: “Under the fundamental rule that no one may be a judge in his own case, the president cannot pardon himself.” While that memo is not law, it could be used to argue for precedent should the situation go to court. Therefore, if a scenario were to arise in which Mr Trump won the 2024 election but was convicted on charges in the state case (a trial is scheduled for March) or in the federal case relating to the Capitol riot, over which he was impeached, he would not be allowed to pardon himself, likely resulting in a massive and costly legal fight to spare him jail time. If he found himself unable to avoid that outcome, the situation would almost certainly lead to a third impeachment or his removal from office via the 25th Amendment, which allows the Cabinet to remove a president who is unable to perform their duties. There are many duties and trappings of the presidency an incarcerated person would simply not be able to carry out from a prison cell, like the viewing of classified materials, to name just one. We are still very much in hypothetical territory at this point, with any potential conviction for Mr Trump still a long way off and little more than a distant possibility. But the conversations he has started with his latest bid for the presidency have already pushed parts of theoretical US constitutional law far further than many experts ever believed they might live to see.
