Science News Roundup: China sends satellites into space in first sea-based commercial launch; Common public screening methods unreliable and more

An international research team on Monday described evidence of potential microbes residing in the harshly acidic Venusian clouds: traces of phosphine, a gas that on Earth is produced by bacteria inhabiting oxygen-free environments. The researchers did not discover actual life forms, but noted that on Earth phosphine is produced by bacteria thriving in oxygen-starved environments.

China sends satellites into space in first sea-based commercial launch

China has successfully sent nine satellites into orbit in its first commercial launch of a rocket from a platform at sea, state media reported on Wednesday. The satellites, one of which belonged to video-sharing platform Bilibili, were deployed by a Long March 11 rocket from the Yellow Sea on Tuesday, media reported.

Common public screening methods unreliable; student athletes may need heart test after COVID-19

The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. COVID-19 screening in public venues is unreliable.

NASA mulls possible mission to Venus after recent discovery of possible life

NASA is considering approving by next April up to two planetary science missions from four proposals under review, including one to Venus that scientists involved in the project said could help determine whether or not that planet harbors life. An international research team on Monday described evidence of potential microbes residing in the harshly acidic Venusian clouds: traces of phosphine, a gas that on Earth is produced by bacteria inhabiting oxygen-free environments. It provided strong potential evidence of life beyond Earth.

Girl power in the deep blue sea: World's largest fish are female

Male and female whale sharks - filter-feeding marine behemoths - grow at different rates, with females doing so more slowly but getting much larger than the guys, according to research that offers deeper insight into the biology of Earth's largest fish. Researchers said on Wednesday they had tracked the growth of 54 whale sharks over a 10-year period in the vast Ningaloo Reef off Australia's west coast, where hundreds of these slow-swimming endangered fish migrate annually.

California wildfire threatens Mount Wilson Observatory and communications hub

Firefighters waged an all-out ground and air campaign on Tuesday to save the famed Mount Wilson Observatory and an adjacent hub of communications towers from a wildfire roaring through rugged peaks overlooking the foothill suburbs north of Los Angeles. Flames from the blaze, dubbed the Bobcat Fire, crept to within just 500 feet (152 meters) of the evacuated observatory grounds during the day, said David Dantic, a spokesman for the Los Angeles County Fire Department.

Hyundai Samho delivers world's first LNG-powered very large container ship

South Korean shipbuilder Hyundai Samho Heavy Industries Co Ltd said on Wednesday it had delivered the world's first very large container ship powered by liquefied natural gas (LNG) to Singapore's Eastern Pacific Shipping Pte Ltd. The shipping industry has been under pressure to reduce carbon emissions, introducing new rules this year to cut the sulphur content in marine, or bunker, fuels.

Potential sign of alien life detected on inhospitable Venus

Scientists said on Monday they have detected in the harshly acidic clouds of Venus a gas called phosphine that indicates microbes may inhabit Earth's inhospitable neighbor, a tantalizing sign of potential life beyond Earth. The researchers did not discover actual life forms, but noted that on Earth phosphine is produced by bacteria thriving in oxygen-starved environments. The international scientific team first spotted the phosphine using the James Clerk Maxwell Telescope in Hawaii and confirmed it using the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope in Chile.

European space agency signs deal for asteroid defence mission

The European space agency (ESA) signed a deal worth 129 million euros ($154 million) on Tuesday to make a spacecraft for a joint project with NASA looking at how to deflect an asteroid heading for Earth. NASA is due to launch a spacecraft in June 2021 set on a collision course with the Dimorphos asteroid to test whether it would be possible to nudge objects that might be threatening Earth onto a safer path.

One of largest known T. rex skeletons up for auction at Christie's

The British auction house Christie's plans to sell the skeleton of one of the largest known Tyrannosaurus rexes in early October, the company said on Wednesday. The dinosaur known as "STAN,", approximately 67 million years old, was discovered in 1987 in South Dakota by amateur paleontologist Stan Sacrison.
