Media playback is unsupported on your device The US space agency's Perseverance robot has left Earth on a mission to try to detect life on Mars.The one-tonne, six-wheeled rover was launched out of Florida by an Atlas rocket on a path to intercept the Red Planet in February next year.When it lands, the Nasa robot will also gather rock and soil samples to be sent home later this decade.Perseverance is the third mission despatched to Mars inside 11 days, after launches by the UAE and China. Lift-off from Cape Canaveral Air Force Station occurred at 07:50 local time (12:50 BST; 11:50 GMT).Nasa made this mission one of its absolute priorities when the coronavirus crisis struck, establishing special work practices to ensure Perseverance met its laun...
Experts pitch surveillance system to detect viruses in wildlife before next pandemic

Experts pitch surveillance system to detect viruses in wildlife before next pandemic

Science
July 9 (UPI) -- Scientific experts said Thursday that a wildlife surveillance system must be developed before the next pandemic emerges. Evidence shows the virus that causes COVID-19, SARS-CoV-2, came from bats that likely passed the virus onto another species before infecting humans, according to the World Health Organization. Advertisement Infectious disease experts, ecologists, wildlife biologists and other experts argue, in a paper published in the journal Science, that a decentralized global system of wildlife surveillance must be established before the next pandemic. "It's impossible to know how often animal viruses spill over into the human population, but coronaviruses alone have caused outbreaks in people three times in the last 20 years," co-author Jennifer Philips said in a pre...
COVID-19 test can detect virus in saliva, blood, urine in 45 minutes

COVID-19 test can detect virus in saliva, blood, urine in 45 minutes

Health
June 12 (UPI) -- A new test is capable of confirming COVID-19 using urine, blood, saliva or mouth-swab samples in 30 to 45 minutes, according to a study published Friday by the journal PLOS ONE. The new platform relies on reverse transcription loop-mediated isothermal amplification, or RT-LAMP, technology, which has been used in the diagnosis of infectious diseases for years, the authors said. Advertisement It's also relatively inexpensive -- both in terms of price and costs associated with use -- they said. "We need more testing options if we are going to be able to stage a successful public health response to coronavirus," study co-author Laura Lamb, a research scientist at Beaumont Hospital in Michigan, told UPI. "This is a rapid test that does not require expensive machinery to run a...
Army solicits bids for wearable technology to detect COVID-19 in early stages

Army solicits bids for wearable technology to detect COVID-19 in early stages

Business
May 9 (UPI) -- The Army is requesting bids for a $ 25 million contract for wearable sensors to detect early symptoms of COVID-19. "There is a dire and urgent need for development of rapid, accurate wearable diagnostics to identify and isolate pre-symptomatic COVID-19 cases and track/prevent the spread of the virus," said the request for proposals issued this week. The RFP does not specify where on the body the device should be worn, and companies bidding for the contract were encouraged to make use of existing technology as much as possible. The RFP was issued by the Medical Technology Enterprise Consortium, which collaborates with the U.S. Army Medical Research and Development Command. The device would allow military services to isolate service members with early symptoms so they can be...
Scientists detect biggest explosion since Big Bang

Scientists detect biggest explosion since Big Bang

Technology
The biggest explosion in the universe since the Big Bang has been discovered by astronomers.The blast came from a supermassive black hole in the Ophiuchus galaxy cluster about 390 million light years from Earth. Scientists say it released five times more energy than anything witnessed before and left a giant dent in the galaxy cluster.Professor Melanie Johnston-Hollitt, from the International Centre for Radio Astronomy Research, said: "This is the most energetic outburst we have seen since the Big Bang."We've seen outbursts in the centres of galaxies before but this one is really, really massive. ...
