Scientists have developed a new laser-based breathalyser test powered by artificial intelligence (AI) that they say can detect COVID-19 in real-time with excellent accuracy. The team from the University of Colorado (CU) <keyword id="107195" type="General" weightage="50" keywordseo="boulder" source="Orion">Boulder</keyword> in the US hopes that the frequency comb breathalyser-essentially using laser light to distinguish one molecule from another-could revolutionise medical diagnostics. "Our results demonstrate the promise of breath analysis as an alternative, rapid, non-invasive test for COVID-19 and highlight its remarkable potential for diagnosing diverse conditions and disease states," said study first author <keyword id="17375478" type="General" weightage="80" keywordseo="qizhong-liang" source="Orion">Qizhong Liang</keyword>, a <keyword id="6435115" type="General" weightage="20" keywordseo="phd" source="Orion">PhD</keyword> candidate at CU Boulder. "There is a real, foreseeable future in which you could go to the doctor and have your breath measured along with your height and weight...Or you could blow into a mouthpiece integrated into your phone and get information about your health in real-time," said <keyword id="2818533" type="General" weightage="80" keywordseo="jun-ye" source="Orion">Jun Ye</keyword>, adjoint professor at CU Boulder and senior author of the study published in the Journal of Breath Research. Between May 2021 and January 2022, the research team collected breath samples from 170 CU Boulder students who had, in the previous 48 hours, taken a polymerase chain reaction (PCR) test, either by submitting a saliva or a nasal sample. Half had tested positive, half negative. Overall, the process took less than one hour from collection to result. When compared to PCR, the gold standard COVID test, breathalyser results matched 85 per cent of the time. For medical diagnostics, accuracy of 80 per cent or greater is considered "excellent". The researchers noted that the accuracy would likely have been higher if the breath and saliva/nasal swab samples were collected at the same time. Unlike a nasal swab, the breathalyser is non-invasive. And unlike a saliva sample, users are not asked to refrain from eating, drinking or smoking before using it, the researchers said. The test doesn't require costly chemicals to break down the sample. And the test could, conceivably, be used on individuals who are not conscious, they said. The breathalyser test consists of a complex array of lasers and mirrors about the size of a banquet table. A breath sample is piped in through a tube as lasers fire invisible mid-infrared light at it at thousands of different frequencies. Dozens of tiny mirrors bounce the light back and forth through the molecules so many times that the light travels about 1.5 miles. Because each kind of molecule absorbs light differently, breath samples with a different molecular make-up cast distinct shadows. The machine can distinguish between those different shadows or absorption patterns, boiling millions of data points down to-in the case of COVID-a simple positive or negative, in a matter of seconds. The researchers are working to miniaturise such systems to a chip scale, allowing for what <keyword id="344472" type="General" weightage="80" keywordseo="liang" source="Orion">Liang</keyword> imagines as "real-time, self-health monitoring on the go".

New AI-powered breathalyser can 'sniff out' Covid in real-time

Mumbai, Jun 23 () Veteran choreographer Saroj Khan has been admitted to a hospital here after she complained of breathing problems. According to a source close to her family, the 71-year old choreographer was rushed to Guru Nanak Hospital in Bandra on Saturday. Following her hospitalisation, a mandatory COVID-19 test was done, which turned out to be negative. "She is fine now and recovering. She had breathing issues and was taken to hospital for that. Her COVID test was done which turned out negative. She doesn't have any symptoms. She is likely to be discharged in a day or two," the source told . In a career spanning over four decades, Khan is credited with choreographing more than 2000 songs. The three-time National Award winner has choreographed for some of the most memorable tracks, including "Dola Re Dola" from Sanjay Leela Bhansali's "Devdas", "Ek Do Teen" from Madhuri Dixit-starrer "Tezaab" and "Ye Ishq Haaye" from "Jab We Met" in 2007. She last choreographed for "Tabaah Hogaye", featuring Madhuri from filmmaker Karan Johar's production "Kalank" in 2019. JUR RB RB RB

Kim Kardashian breaks silence on Kanye West's mental health and asks for 'compassion and empathy'

By Aditi Khanna London, Jun 30 () A surge in the number of coronavirus infections has resulted in an extended lockdown being imposed from Tuesday on the eastern England city of Leicester, which has one of the country's largest India-origin populations. UK Health Secretary Matt Hancock confirmed the extension for the Leicestershire region in the House of Commons for at least two weeks more than the rest of England, which is preparing to substantially lift restrictions from this Saturday. "We recommend to people in Leicester, stay at home as much as you can, and we recommend against all but essential travel to, from and within Leicester," Hancock told Parliament on Monday evening. "We'll monitor closely adhering to social distancing rules and we'll take further steps if that is what's necessary… If we are – as a nation – to ease from lockdown smoothly, then those areas that do see flare-ups will need greater speed in the response, otherwise we risk no moles getting whacked," he said. The Cabinet minister said the city had "10 per cent of all positive cases in the country over the past week". This means pubs, restaurants, hotels and hairdressers preparing to reopen will have to delay their plans for reopening from this weekend. Suburbs of Leicester, such as Oadby, Birstall and Glenfield, will also be affected, and the health minister said details of the wards in Leicestershire covered by the new lockdown measures would be published "imminently". Leicester's seven-day infection rate of 135 cases per 100,000 people was "three times higher than the next highest city" and admissions to hospital were between six and 10 per day – compared to about one a day at other trusts. The re-imposition of stricter social distancing norms mean all non-essential shops will close from Tuesday and schools for most pupils, except those of key workers, will be close from Thursday. The relaxation of shielding measures on 6 July – which will allow the most clinically vulnerable to spend more time outside – will also not take place in the city. It comes after Leicester City Council reported 944 positive tests in the two weeks to 23 June – about one in 16 of the total UK cases during that period. Mayor of Leicester Sir Peter Soulsby said the measures imposed by the government were "stricter than we anticipated but we understand the need for firm action". "I can understand it from (the government's) perspective – they are entirely convinced that the level of the transmission of the disease in Leicester is at a higher level than I think the figures show," he said. Leicestershire County Council leader Nick Rushton said "protecting residents is our main concern" and added it "makes sense to step up restrictions in areas closer to the city". Besides, the local councils will be provided extra funding to enhance communications to the population on COVID-19 in all relevant languages, including Gujarati – a common language spoken among the city's Indian-origin residents. A walk-in test centre as well as mobile testing units are being made available to Leicester. The government said it is trying to "get to the bottom" of the potential reasons behind the spike in the region but it is feared that the large ethnic minority population of Leicestershire makes it more vulnerable to the deadly virus – as highlighted by a previous Public Health England review which found that ethnic minorities were at a higher risk from coronavirus. Rakesh Parmar, an Indian-origin owner of the Ye Olde Sweet Shoppe in the city centre, was among the local business people who said the further restrictions would mean a hard financial hit but understood why they were required. "The impact of coronavirus hit us on 23 March, we closed for 10 weeks, and then opened again on 15 June – it's been one long slog," he said. Local politicians, including Leicester East MP Claudia Webbe, have accused the government of taking a hasty approach to lifting lockdown restrictions. South Leicestershire MP Alberto Costa said he was working to get "necessary clarity" over the areas affected by the localised lockdown. AK PMS PMS
