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."

La Vigna di Leonardo, said to have been da Vinci's vineyard, has been closed after French billionaire Bernard Arnault bought the property. Now, nobody knows if the site will reopen to the public -- or sell its wine for charity, as before.

Scientists have unearthed a new species of wasp in the Amazon – and it's rather terrifying. The alien-looking parasitic creature came to light when a team at Utah State University were researching Allpahuayo-Mishana National Reserve in Peru. The wasp, known as Capitojoppa amazonica, has a giant almond-shaped head and is known to latch on to prey before sucking its blood and then eating it from the inside. It does so by laying eggs in its victims including caterpillars, beetles and spiders. The study’s lead author, biologist Brandon Claridge called the practice a "solitary endoparasitoid". "Once the host is located and mounted, the female will frantically stroke it with her antennae," Claridge told Live Science in an email. "If acceptable, the female will deposit a single egg inside the host by piercing it with her ovipositor (a tube-like, egg-laying organ)." He went on to explain that in some instances, "females will even stab the host with the ovipositor and feed without laying an egg as it helps with gaining nutrients for egg maturation." This isn't the first horrifying discovery, with researchers recently finding a new species of tarantula in Thailand that is characterised with illuminous blue legs. The spider is one of the rarest in the world, with Dr Narin Chomphuphuang explaining how it lurks in hollow trees. "The difficulty of catching an electric-blue tarantula lies in the need to climb a tree and lure it out of a complex of hollows," he explained. "During our expedition, we walked in the evening and at night during low tide, managing to collect only two of them."

Four children from Ukraine are to be to be returned to their families from Russia in a deal brokered by Qatar. The youngest is two years old, while the oldest is 17. A seven-year-old boy returned to Ukraine on Monday via Estonia after he was reunited with his grandmother in Qatar's Moscow embassy last week, the official said. The two-year-old boy was handed over to Qatari diplomats in Moscow on Monday, and a nine-year-old boy and a 17-year-old girl are due to be handed over this week, the official said. The Ukrainian Presidential Office said the children would all be home soon. "We are bringing home four Ukrainian children illegally deported to the Russian Federation," Andriy Yermak, head of the presidential office, said on X, formerly known as Twitter. He gave no further details. Kyiv says about 20,000 children have been taken from Ukraine to Russia or Russian-held territory without the consent of family or guardians. It calls this a war crime that meets the UN treaty definition of genocide. Moscow, which launched a full-scale invasion of Ukraine in February last year, denies committing the accusation and says it has protected vulnerable children from the war zone. The return of the first four children tests a system the Gulf Arab state established after months of secret talks with Moscow and Kyiv, the Qatari official said on condition of anonymity because of the sensitivity of the process. Qatar's minister of state for international cooperation, Lolwah Al Khater, confirmed the mediation in a statement and described this week's repatriations as "only a first step". Russia's Commissioner for Children's Rights, Maria Lvova-Belova, shared a short initial list of Ukrainian children to be returned with a team of Qatari diplomats who verified each child's identity, the official said. It was not clear how many additional children Russia would authorise to return to Ukraine via the Qatari mechanism, the Qatari official said. About 400 children have been returned to Ukraine since Moscow's invasion, but the United Nations human rights agency raised concerns last week that there was no system to facilitate such returns. Qatari diplomats will accompany the children over the border with Estonia, Latvia or Belarus or to Qatar by chartered jet before returning them to Ukraine, the Qatari official said. "Both Ukrainian and Russian officials have been cooperative," the Qatari official said, adding that Ukraine approached Doha to mediate with Russia over the children. The seven-year-old boy reunited with his grandmother on Friday had been in Russia at a children's home "as a result of being separated from his mother who was in Russia when the war broke out", a Qatari official told Reuters. The International Criminal Court issued arrest warrants in March for Russian President Vladimir Putin and Ms Lvova-Belova, accusing them of the war crime of illegally deporting children from Ukraine. Both deny the allegations against them.

Vladimir Putin arrived in Beijing on Tuesday for a rare trip abroad to join ally China in marking the 10th anniversary of an international cooperation forum. The two-day visit is only his second known trip abroad since the Hague-based International Criminal Court (ICC) issued an arrest warrant for the Russian leader in March over Ukraine war crime allegations. The Russian president and his Chinese counterpart Xi Jinping are holding talks to bolster their shared trade and security amid Western sanctions against Moscow over Mr Putin’s invasion of Ukraine. Several other world leaders also arrived in Beijing for the Belt and Road Initiative (BRI) forum championed by Mr Xi, including Vietnam’s president Vo Van Thuong, but Mr Putin is being heralded as the talks’ chief guest. The Russian presidential entourage was greeted by Chinese commerce minister Wang Wentao after Mr Putin’s plane touched down at the Beijing Capital International Airport on Tuesday. Beijing has supported Russia in rejecting resolutions on Ukraine in the United Nations Security Council, part of Western efforts to isolate Russia over the war. China has rejected Western criticism of its close partnership with Russia in spite of the war in Ukraine, which entered its 600th day on Monday. Mr Putin is expected to hold bilateral meetings with his counterparts from Vietnam, Thailand, Mongolia and Laos on Tuesday and attend the forum’s official opening reception hosted by Mr Xi, Tass news agency reported. On Wednesday, he will address the forum after Mr Xi as the chief guest and will meet the Chinese president for talks after. Before embarking on the trip, Mr Putin said in an interview with CCTV that he had met with Xi more than 40 times so far and the two have “many fond memories”. He praised China’s ambitious BRI project and said contrary to the West’s perception, Beijing was seeking cooperation and not to “put someone under its thumb”. China launched its signature BRI project in 2013 and funded $900bn in infrastructure and other projects to connect Asia with Africa and Europe through overland and maritime routes. The project has since faced many challenges, including concerns about debt sustainability and the impact of China’s economic slowdown. Mr Putin said his meeting with Mr Xi would encompass talks on Belt and Road-related projects, which he said Moscow wanted to link with efforts by an economic alliance of ex-Soviet Union nations mostly located in Central Asia to “achieve common development goal”. This is his second visit outside Russia after his visit to Kyrgyzstan, a former Soviet republic, earlier this month. The ICC accused Mr Putin of committing a war crime by “illegally deporting children from Ukraine”. The ICC obliges the court’s 123 member states to arrest Mr Putin and transfer him to The Hague for trial if he sets foot on their territory. The Kremlin leader last visited China for the Beijing Winter Olympics in February 2022 when Mr Xi declared a “no-limits" partnership with Russia. Mr Xi met Mr Putin in March during a three-day trip to Moscow amid the Pentagon’s fears of Beijing’s potential military cooperation between the two countries for supplying weapons to be used in Ukraine. They greeted one another as “dear friend” when they met in the Kremlin, and held informal talks for over four hours.
