Richard Barclay opens a metal drawer in archives of the Smithsonian Natural History Museum containing fossils that are nearly 100 million years old. Despite their age, these rocks aren't fragile. The geologist and botanist handles them with casual ease, placing one in his palm for closer examination.

Embedded in the ancient rock is a triangular leaf with rounded upper lobes. This leaf fell off a tree around the time that T-rex and triceratops roamed prehistoric forests, but the plant is instantly recognizable. "You can tell this is ginkgo, it's a unique shape," said Barclay. "It hasn't changed much in many millions of years."

France's pharmaceutical giant Sanofi, which has lagged behind rivals in developing new generation mRNA Covid-19 vaccines, on Tuesday said it has purchased a U.S. firm specializing in the technology.

Sanofi will buy Translate Bio, with which it has been working to develop an mRNA Covid jab, for $3.2 billion (2.7 billion euros), the company said in a statement.

Imagine a Covid-19 vaccine that came as a pill: no needles, no medical professionals required to administer it, potentially delivered directly to people's homes.
