 Matter of potency
World Health Organization experts and a range of other scientists
refuted the claims of Professor Alberto Zangrillo, head of intensive
care at Italy's San Raffaele Hospital in Lombardy, which bore the
brunt of Italy's epidemic, that the new coronavirus was losing its
potency.
Zangrillo told Reuters: "We have never said that the virus has
changed, we said that the interaction between the virus and the host
has definitely changed."
He said this could be due either to different characteristics of the
virus, which he said they had not yet identified, or different
characteristics in those infected.
Live with the virus
Pakistan's Prime Minister Imran Khan cited economic losses and the
inability of his government to continue cash handouts to the poor on
such a large scale, to justify lifting a coronavirus lockdown
despite rising infections and deaths.
In a televised address, Khan said Pakistan couldn't afford to match
the losses incurred during the lockdown as many other countries had
done, adding: "If people do take care they can live with the virus."
Air bridges
British government ministers are mulling options to replace
quarantines for people arriving at airports by the end of June, one
being the idea of air bridges, the Telegraph newspaper reported.

The policy of air bridges is meant to enable people from other
countries who have achieved lower levels of coronavirus infection to
come to Britain. The quarantine policy, which requires all
international arrivals to self-isolate for 14 days, goes into effect
from June 8, Interior Minister Priti Patel said in May.
Save the crabs
Wildlife advocates are pushing drugmakers to curb the use of prized
horseshoe crab blood by switching to a synthetic alternative called
recombinant Factor C (rFC) for safety tests that detect bacterial
contamination in intravenous drugs or implants, including those
needed before a COVID-19 vaccine can be used on humans.
This shift could save 100,000 horseshoe crabs annually on the U.S.
East Coast alone and help threatened migratory birds that depend on
crab eggs for survival, say the National Audubon Society, Defenders
of Wildlife and other groups.
Horseshoe crabs' milky-blue copper-rich blood has helped the species
to survive for 450 million years - and made it a source of one of
the drug industry's most unusual raw materials because it clots in
the presence of bacterial endotoxins.
