When the going gets tough, women are tougher than men

Women live longer than men through famine, epidemics and other trials.

When men and women are subjected to harsh conditions, it’s the women who live longer.

James Vaupel at the University of Southern Denmark in Odense and his colleagues studied seven populations that endured famine, epidemics or enslavement. The researchers found that during crises, girls and women lived longer than their male counterparts. For example, in Ireland during the Great Famine, which lasted from 1845 to 1849, life expectancy dropped from around 38 years for both sexes to about 19 years for men and 22 years for women.

The team traced much of the effect to infancy: newborn girls were more resilient than newborn boys. The minimal behavioural differences between male and female infants suggest that the difference in survival at that age is biological, the authors say.

Ember and thick smoke from bushfires reach Braemar Bay in New South Wales

Vast bush fires that swept across Australia at the end of 2019 and the start of 2020 filled the skies with enough smoke to warm a portion of the atmosphere. Credit: Saeed Khan/AFP/Getty

Atmospheric science

Smoke from Australian fires turned up the heat in the southern sky

The catastrophic wildfires of late 2019 and early 2020 triggered a lingering temperature rise in a section of Earth’s lower atmosphere.

Small farms outdo big ones on biodiversity — and crop yields

Large-scale farms account for most of the global food supply, but smallholdings protect species and are just as profitable.
