Why Did Dozens Of Dolphins Die In Argentina?

Scientists are investigating why 68 dolphins — most of which were dead —washed ashore this week in the central province of Chubut.

PUERTO MADRYN — Were they sick? Were they chased ashore by hungry orcas? Those are two of the theories scientists are considering following the discovery this week of nearly 70 beached dolphins — many of them already dead — near Puerto Madryn in central Argentina's Chubut province.

For now, though, the dolphin deaths are still very much a mystery. "We don't know for certain what caused this dolphin stranding," Mariano Coscarella, a researcher at the government scientific agency CENPAT told Clarín. "We don't have enough clues to really clarify the matter yet."

Coscarella said that he and his colleagues counted 68 common dolphins in total. Together they managed to return 19 to the water. The rest died. The CENPAT researcher also said the animals appeared intact. Adding to the mystery is that this is the first such mass stranding ever recorded in the Golfo Nuevo, as the water around Puerto Madryn is known.

The scientists plan to perform necropsies on the corpses. Hopefully that'll provide additional clues. One of Coscarella's CENPAT colleagues, Silvana Dans, isn't ruling out the possibility that the dolphins were "corralled" by killer whales and thus pushed off course — and ultimately onshore.

"We know from other cases studied that there could have been a pursuit by orcas," said Dans. "The dolphins could have felt trapped." Another hypothesis, given that the dead dolphins are part of a single group is that they were victims of "some kind of epidemic," she added.

The CENPAT researchers were also surprised to find such a large batch of common dolphins. "That's unusual here," said Dans, who explained that the more prevalent species in the area is the dusky dolphin.

Whatever the cause, the scientists will have to be patient. The necropsies and other tests are expected to take several weeks.

Colombia Celebrates Its Beloved Drug For The Ages, Coffee

This essential morning drink for millions worldwide was once considered an addictive menace, earning itself a ban on pain of death in the Islamic world.

Colombia's star product: coffee beans.

BOGOTÁ — October 1st is International Coffee Day. Recently it seems as if every day of the calendar year commemorates something — but for Colombia, coffee is indeed special.

For almost a century now we have largely tied our national destiny, culture and image abroad to this drink. Indeed it isn't just Colombia's star product, it became through the course of the 20th century the world's favorite beverage — and the most commonly used drug to boost work output.

Precisely for its stimulating qualities — and for being a mild drug — coffee was not always celebrated, and its history is peppered with the kinds of bans, restrictions and penalties imposed on the 'evil' drugs of today.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
