Bears’ Cave, Romania | #Geology #GeologyPage #Cave #Romania

Bears’ Cave is located the western Apuseni Mountains, on the outskirts of Chiscau village, Bihor County, northwestern Romania. It was discovered in 1975 by “Speodava”, an amateur speleologist group.

Bears’ Cave received its name after the 140 cave bear skeletons which were discovered on the site in 1983. The cave bear, also known as Ursus spelaeus, is a species of bear which became extinct during the Last Glacial Maximum, about 27,500 years ago.

The cave has three galleries and four halls: the Candles Hall, the Spaghetti Hall, Emil Racovita Hall, the Bones Hall.

M16: In and Around the Eagle Nebula
Image Credit & Copyright: Andrew Klinger

Explanation: From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and dust. The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of the Serpent (Serpens). This picture involved over 25 hours of imaging and combines three specific emitted colors emitted by sulfur (colored as red), hydrogen (yellow), and oxygen (blue).

ASHG 2018 open thread

The American Society of Human Genetics (ASHG) annual meetings kicks off tomorrow in San Diego. Feel free to post anything near and far related to this event in the comment thread below.
You can explore this year’s offerings via the online planner/abstract search located HERE. See anything really interesting? Here’s what I found after a quick search using the term “ancient”. Hopefully someone tweets from the South Asian talk.

Mount Lebanon provides an opportunity to study DNA from the ancient Near East
Reconstructing the peopling of old world south Asia: From modern to ancient genomes
Tracing the evolution of pigmentation-associated variants in Europe

Intriguingly, the Mount Lebanon abstract says this:

In addition, we found steppe-like ancestry in the Roman Period individuals which we have previously detected in present-day Lebanese but not in Bronze Age individuals. This supports our previous proposition that the steppe ancestry penetrated the region more than 2,000 years ago, and genetic continuity in Lebanon is substantial.

So what are we dealing with here exactly: admixture from the Hittites, Mittani, and/or Romans? Who does the Global25 point to?
