Cave paintings confirm mystery European bison species

Ice-age hunters had an intimate knowledge of the animals they coexisted with — and this familiarity is clearly depicted in paintings on cave walls throughout Europe. Inside a cave in France, scientists recently identified artistic evidence dating to about 17,000 years ago of a previously unknown hybrid species of cattle crossed with bison. The paintings confirm findings from recent genetic studies of fossil bison, the researchers say.

Down to Earth With: Underwater cave explorer Jill Heinerth

Jill Heinerth has trekked farther into caves than any woman in history and logged more than 7,000 dives across every continent and up to roughly 140 meters underwater — recreational divers only reach depths up to 40 meters. She has dived inside icebergs in Antarctica, beneath the Sahara Desert, and in the turquoise waters of the Bahamas.

Cave dripwater records wildfires

Water seeps through soil and bedrock before dripping from the roof of a cave and carries with it elements of the outside world and its climate history. That is why speleothems, cave structures formed via precipitation, can be studied as climate proxies. New research suggests that the chemistry of the cave dripwater can also contain the signature of wildfires that burned outside the cave, on the ground above the cave’s roof, yielding a more complex picture of the past.

Chinese cave art reveals record of climate change

In times of drought, Dayu Cave in the Qinling Mountains of central China has remained a reliable source of water, and since at least the 16th century, thirsty visitors to the cave recorded their pilgrimages on the walls. Now the graffiti — rendered in black pigment on the yellow cave walls — is providing scientists with a unique record of how climate change affected nearby communities between 1520 and 1920.

Ancient cave art discovered in Indonesia

Europe has long been thought to have been the home of the oldest art in the world — including a stash of cave paintings in northern Spain that date to about 40,000 years ago — but a new dating technique may put Indonesia on the ancient art map as well.

Ancient storms recorded in Yucatán cave

Today, one can find a plethora of records about coastal storms — everything from local news footage of wading meteorologists to the moment-to-moment wind speeds and barometric pressures of entire seasons of Atlantic hurricanes recorded in NOAA databases. Ancient storms are harder to track, unless they left a mark in the geologic record. Now, researchers have a new proxy record, one of the longest to date, to study ancient storms.

Southeastern caves shuttered to slow the spread of bat-killing disease

On June 2, the U.S. Forest Service moved to close all caves and underground mines on national forest lands in the 13 states in its southern division for five years. The goal is to halt the spread of White Nose Syndrome, a disease that has already killed 5 million bats.

Ancient skeleton found in underwater cave reveals DNA of earliest Americans

The 12,000- to 13,000-year-old remains of a teenage girl — the oldest, most complete, genetically intact human skeleton discovered in the New World — were found in the Hoyo Negro cave on Mexico’s Yucatán Peninsula.

Getting there and getting around in Cuba

Because of the U.S. embargo against Cuba, U.S. citizens must go through a travel agency licensed by the U.S. Treasury Department that provides “people-to-people” travel to Cuba for U.S. citizens. Because booking with this type of travel agency is required, the U.S. State Department’s website on visiting Cuba is a great place to start: http://travel.state.gov/travel/cis_pa_tw/cis/cis_1097.html.
