In the brief span of two months, a series of disasters have swept across the globe. Hurricanes in the Gulf Coast and the Caribbean left homes, businesses, and streets flooded, disarmed power grids and basic services, and devastated the communities that rely on them. An earthquake in Mexico spurred mass evacuations and toppled buildings. Floods in South Asia killed thousands and shut millions of children out of school.

Some animals use tools too, like the macaques of Thailand, who have figured out that their favorite shellfish snacks are much easier to eat if they bash them open with rocks first. They’ve become proficient shellfish ...read more

When it comes to allocating blame for tooth decay, one of the most common chronic childhood diseases worldwide, experts point fingers at both genes and dental hygiene as causes.

In Australia, a question lingers: Do we shoot the kangaroos?
The proposition sounds a bit inhumane at first blush, after all, the kangaroo stands proudly on the Australian coat of arms. The bouncing beasts are a fixture of the outback. But in recent years, the roos have been doing quite well—in fact, too well. Their numbers have been bolstered by the extinction of natural predators and generous rainfall; there are now so many kangaroos, that one ecolog ...read more
