A paper in the BMJ shows that deaths from Covid 9 are being massively overlooked in Zambia. The new data come from post-mortem tests at the University Hospital mortuary in Lusaka, showing that at least 1 in 6 deaths there are due to the coronavirus; many of the victims had also been suffering from tuberculosis. Chris Gill of Boston University’s Department of Global Health, and Lawrence Mwananyanda, chief scientific officer of Right to Care, Zambia, discuss their findings with Roland Pease.
New variants of concern continue to be reported, such as the one labelled B 1 1 7 in the UK, or B 1 351 identified in South Africa. Geneticist Emma Hodcroft, of the University of Bern, talks about seven variants that have been found in the US. Although all these variants are evolving from different starting points, certain individual mutations keep recurring – which suggests they have specific advantages for the virus. Her co-author Jeremy Kamil, of Louisiana State University Health Sciences Center in Shreveport, explains how he can watch the viruses replicating inside cells.
Much of the United States, as far south as Texas, and Eurasia, has been gripped by an extraordinary blast of Arctic weather. Roland hears from climatalogist Jennifer Francis, of the Woodwell Climate Research Center, about the Arctic’s role in this weird weather.
Life, in the form of sponges, has been discovered hundreds of metres under the thick ice surrounding Antarctica, where it’s dark, subzero and barren. The British Antarctic Survey’s Huw Griffiths reveals how it was spotted unexpectedly in pictures colleagues took with a sub-glacial camera.

A conversation with the author of the new book “Layered Money: From Gold and Dollars to Bitcoin and Central Bank Digital Currencies.”
This episode is sponsored by Nexo.io.
Nik Bhatia is a financial researcher, a CFA charterholder and an Adjunct Professor of Finance and Business Economics at the University of Southern California Marshall School of Business.
Nik’s new book “Layered Money: From Gold and Dollars to Bitcoin and Central Bank Digital Currencies” puts the rise of bitcoin into a larger historical context - from the first coinage of Rome to the introduction of credit in Renaissance Florence to the beginnings of interest rate trading in Antwerp to the genesis of the central bank system that shapes money today.
In this conversation, he and NLW do a rapid tour across those two millennia of economic history, ultimately helping reframe what it means when we say that bitcoin is the new “digital gold.”

Crippling blackouts can be explained in part by the state’s unique energy market, but the disaster exposes wider failures that must be confronted amid a changing climate. Today’s landing of another Mars rover broadens the hunt for evidence of extraterrestrial life—an effort that is expanding faster and farther than ever before. And soft rock shakes off its milquetoast manner.
