Hi, I'm Scientific American podcast editor Steve Mirsky. And here's a short piece from the December 2019 issue of the magazine, in the section called Advances: Dispatches from the Frontiers of Science, Technology and Medicine. 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.

From Russia:
Scientists identified a small group of Nordmann's greenshanks, among the most endangered shorebirds, in a bog in Russia's far eastern region. They helmed the first in-depth study of the bird since 1976 and are the first ever to capture a photograph of an adult on a nest.
From New Zealand:
Researchers found that humpback whales traveling near Raoul Island, 700 miles off New Zealand's coast, learn songs from members of other breeding grounds.
From Indonesia:
Climate models have more firmly connected a record-setting cold European summer in 1816 to the previous year's eruption of Indonesia's Mount Tambora, which injected sulfur dioxide into the atmosphere and caused widespread surface cooling.
And from Brazil:
A newfound species of electric eel, Electrophorus voltai, produces the strongest shock scientists have ever measured from a living animal. It can produce 860 volts at up to one amp of current.
That was "Quick Hits," by Sarah Lewin Frasier.
