The first synthetic element p.570

When Mendeleev proposed his periodic table in 1869, element 43 was unknown. In 1937, it became the first element to be discovered by synthesis in a laboratory — paving the way to the atomic age.

A gut punch fights cancer and infection p.573

Microorganisms in the human gut can affect immune-system cells. Gut bacterial strains have been discovered that boost immune cells that have cell-killing capacity and that can target cancer and protect against infection.

Intron RNA sequences help yeast cells to survive starvation p.578

Intron sequences are removed from newly synthesized RNA and usually rapidly degraded. However, it now seems that introns have a surprising role — helping yeast cells survive when nutrients are scarce.
