Editor's note

Imagine researching climate science at a corporation and discovering later that the company’s public statements on climate change emphasized uncertainty and doubt. This is exactly what happened to atmospheric scientist Katharine Hayhoe, whose work was funded by Exxon in the mid-1990s. She describes the shock she’s experienced in learning of Exxon’s attempts to mislead the public on climate change all while funding cutting-edge research on the same issue – and the difficult questions this episode poses for scientists and academics.

While eyes and vision protection received a lot of attention recently as millions observed the total eclipse,the protection of smell and taste are important, too, writes Steven Munger of the University of Florida. Yet people who have smell and taste disorders face difficulty being diagnosed and treated – and even in finding support to improve their quality of life, Munger offers a “smell test” to see what you might know about these important senses.

That some new mothers experience postpartum depression has become better known. But fewer people realize that new fathers, too, can have the same sad and hopeless feelings. A new study by psychologist Darby Saxbe finds dads’ depression can be tied to their testosterone levels – and that it has a surprising upside for the other members of the family.

  • Why students need better protection from loan fraud

    Richard Fossey, University of Louisiana at Lafayette

    Students across the country have been defrauded by for-profit schools. Fine print in their enrollment contracts has stopped them from bringing their cases to court, but new rules could help.

Today’s quote

Despite the skepticism, postpartum depression in fathers is very real, with estimates that around 10 percent of men report symptoms of depression following the birth of a child, about double the typical rate of depression in males.
