Boom and busted.

In trying to untangle a mysterious herring collapse from the aftermath of the Exxon Valdez oil spill, scientists in Prince William Sound are revealing just how resilient—and unpredictable—marine ecosystems can be.

On a cold day in June, Scott Pegau leans toward the passenger window of a Cessna floatplane and peers out at the teal waters of Prince William Sound. The glacier-rimmed pocket of seawater on the southern coast of Alaska is protected from the open ocean by a string of rugged islands. It is both moody and alluring. Clouds dally on the snowy peaks and fray against the forested hillsides. The sea is flat and frigid, except for a single row of waves lapping at the rocky shore.

What the hard lessons of rubella teach us about a Zika vaccine.

Imagine that you are pregnant, unexpectedly. You are terrified, but not because you don’t want a baby. You are in fact, happily married, and you have been intending to start a family soon. Rather, you are terrified because an epidemic of a viral disease is raging around you. It is a disease that is often so mild that people aren’t aware that they have it. But when it infects a woman early in her pregnancy, it devastates the fetus, shrinking its head and addling its brain. There is no effective treatment and there is no vaccine.

Many have been treated with multiple medications in their short lives: antibiotics, anesthetics, narcotics, diuretics.

Smoking during pregnancy may lead to later substance use in the child.

Smoking during pregnancy is a well-known risk factor for many health problems in children, including low birth weight, heart defects and asthma. In our latest study, we show that smoking in pregnancy also increases the risk for children’s later tobacco smoking, as well as alcohol and cannabis use. This effect may be partly explained by so-called epigenetic changes at birth, in genes important for brain function and development.

Manganese in wells more widespread than previously thought.
