Science News Briefs from around the Globe

Here are some brief reports about science and technology from all over, including one from the United Arab Emirates about the the first interplanetary mission by an Arab country.

Science, Quickly

Hi, I’m Scott Hershberger, with Scientific American as an American Association for the Advancement of Science Mass Media Science and Engineering Fellow. And here’s a short piece from the October 2020 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 stories from around the globe.

From Mexico: In now flooded caves, researchers discovered the oldest known ochre mines in the Americas. Around 12,000 years ago inhabitants of the Yucatán Peninsula extracted the red pigment, possibly for use as an antiseptic and sunscreen or for symbolic purposes such as body painting.

From Italy: A massive bloom of pink algae, triggered by low snowfall and high spring and summer temperatures, could accelerate the melting of the Presena glacier by causing the ice to absorb more sunlight.

From Botswana: At least 350 elephants have dropped dead in the Okavango Panhandle since March, and live elephants have acted disoriented or seemed partially paralyzed. With poaching and anthrax ruled out as potential causes, investigators suspect an unknown disease.

From Libya: A seven-million-year-old crocodile skull suggests the prehistoric animals may have traveled from Africa to the Americas. Computerized tomography of the fossil, found in Libya, revealed a slight bump in the middle of the snout—a feature of modern American crocodiles but not their African counterparts.

From Polynesia: Through a genetic analysis of modern-day Polynesians and Indigenous people from South America’s Pacific coast, scientists concluded the two groups came into contact between A.D. 1150 and 1230. Where the transoceanic encounter occurred remains unknown, but the team suspects eastern Polynesia.

And from the United Arab Emirates: The successful launch of a Mars orbiter called Hope marked the first interplanetary mission conducted by an Arab nation. Carrying instruments to study the Red Planet’s daily and seasonal weather, the spacecraft is set to enter Martian orbit in February 2021.

That was “Quick Hits.” I’m Scott Hershberger.
