Confirmed coronavirus cases are rising faster than ever

  • In April, new cases never topped 100,000 in one day, but since May 21, there have only been less than 100,000 on five days, according to data from Johns Hopkins University.
  • But many countries, particularly in South America, the Middle East and Africa, the rate of transmission still appears to be accelerating, according to a CNN analysis of Johns Hopkins University data.
  • Its case numbers are second only to the US, where just under 1.9 million cases have been reported and 108,211 deaths.
  • A number of countries that passed their initial peak -- such as South Korea, Germany and China -- have since seen new clusters of infections after restrictions on movement were eased, raising fears of a second wave.
  • Authorities in 214 countries and territories have reported about 6.6 million Covid-19 cases and 391,000 deaths since China reported its first cases to the WHO in December.

Oldest known parasite is a worm-like animal from 512 million years ago

  • Hundreds of fossilised animals seemingly covered in worm-like creatures are the oldest hard evidence of parasitism, dating from 512 million years ago when complex animals were still new.
  • Zhang’s team found hundreds of fossilised brachiopods, animals with two shells resembling those of clams, called Neobolus wulongqingensis.
  • Evidently these animals lived with the brachiopods, but was it a cooperative relationship or a parasitic one?
  • If the worm-like creatures were parasites, brachiopods that hosted them should have been less healthy than those without them.
  • Strotz also argues that they were obligate parasites, meaning they couldn’t survive without their hosts, but Ma says there isn’t enough evidence.
  • “We don’t know what this tube-dwelling organism is,” says Ma. It isn’t clear whether the creatures are some of the first animal parasites, or if there were older examples that haven’t been fossilised.

The pandemic will put billionaires’ commitment to journalism to the test

  • Over the last decade, billionaires like Powell Jobs have picked up prestige media outlets and won respect from those who saw these deals as a form of civic leadership and public service.
  • And what decisions these billionaires make will be telling about a larger trend: Have their purchases over the last few years been an expression of pure philanthropy — a charitable commitment that they expect to lose money on, or at least are prepared to — as they and their admirers have made them out to be, or are they a financial investment and therefore subject to the same cold, hard math that applies to businesses like Amazon or Salesforce?
  • When the Atlantic deal was announced in 2017, Powell Jobs called the publication “one of the country’s most important and enduring journalistic institutions,” and waxed eloquent about the publication’s 160-year history and ties to Ralph Waldo Emerson, after whom her philanthropy, Emerson Collective, is named.
