Sand dunes are among nature’s loveliest wonders, forming undulating mounds in deserts, on beaches, and even underwater. Dunes are also known to migrate—and now a new study suggests that they “communicate” as they move. Of course, as inanimate objects, the dunes are not speaking; the new research, published in the journal Physical Review Letters, focuses

Billions of desert locusts are swarming across eastern Africa—mainly affecting Kenya, Somalia, and Ethiopia but likely to spread further. The swarms are massive; one of the largest in Kenya is about 37 miles long and 25 miles wide. For reference, that could cover more than half of Long Island. The swarms, which are dense enough
