Hi, I’m Scientific American podcast editor Steve Mirsky.

The article is titled Quick Hits, and it’s a rundown of some science and technology stories from around the globe, compiled by assistant news editor Sarah Lewin Frasier.
From Spain: Summer’s powerful drought revealed a more than 4,000-year-old oval of at least 100 standing stones called the Dolmen of Guadalperal, which had been submerged since 1963 in an engineered reservoir.
