Sisters Make Us Happier

"Having at least one female sibling makes us happier and less prone to depression, especially if our parents were divorced. This effect seems to persist into adulthood."

Linguist Deborah Tannen comments on research indicating that sisters provide more emotional support than brothers: "I interviewed more than 100 women about their sisters, but if they also had brothers, I asked them to compare. Most said they talked to their sisters more often, at greater length and, yes, about more personal topics. This often meant that they felt closer to their sisters, but not always. One woman, for example, says she talks for hours by phone to her two brothers as well as her two sisters. But the topics differ. She talks to her sisters about their personal lives; with her brothers she discusses history, geography and books. And, she added, one brother calls her at 5 a.m. as a prank."

Surprising Science
  • New research on beetles shows that successive exposure to heatwaves reduces male fertility, sometimes to the point of sterility.
  • The research has implications both for how the insect population will sustain itself as well as how human fertility may work on an increasingly hotter Earth.
  • With this and other evidence, it is becoming clear that more common and more extreme heatwaves may be the most dangerous aspect of climate change.
