Cases, deaths climb worldwide as COVID-19 mortality rate declines to 4.4%

World
July 12 (UPI) -- Coronavirus has spread worldwide since the pandemic began earlier this year, rising exponentially in deaths to more than 567,000 and nearly 13 million cases. But despite those grim statistics, the mortality rate -- comparing deaths and cases -- has been declining. On May 1, the mortality rate was 7.2 percent but on Saturday it had decreased to 4.4 percent overall. Advertisement Seventy-two days ago, the death count was 240,976 and cases were 3,351,722. Deaths have more than doubled to 567,035, while cases almost quadrupled to 12,884,231. On Saturday, there were 214,786 new cases, below the record of 236,918 the day before. Deaths rose by 4,996 Saturday compared with 5,684. Since the first deaths were reported in Wuhan, China, the outbreak spread to Europe, then the United...
Seismic surveys responsible for high zooplankton mortality rates

Seismic surveys responsible for high zooplankton mortality rates

Science
June 23 (UPI) -- Seismic surveys carried out by the oil and gas industry are causing high mortality rates among zooplankton, according to new research out of Australia.Seismic air guns are frequently used on marine petroleum expeditions. New research found the air blasts dramatically increase mortality rates among target zooplankton species. Testing also showed the air gun's negative impact extends well beyond previous range estimates.Testing revealed air gun pulses yielded between an 18 and 60 percent increase in zooplankton mortality rates. The seismic blasts also killed al zooplankton larva. These effects extended across nearly 4,000 feet. It was previously believed the negative impact of seismic air guns was limited to roughly 30 feet.The findings -- detailed in a study published Thurs...
