An archaeological excavation on Mount Zion in Jerusalem has found clear evidence of the Babylonian conquest from 587/586 B.C. 

The discovery is of a deposit including layers of ash, arrowheads dating from the period, as well as Iron Age potsherds, lamps and a significant piece of period jewelry - a gold and silver tassel or earring. There are also signs of a significant Iron Age structure in the associated area, but the building, beneath layers from later periods, has yet to be excavated.

The use of social media is ubiquitous in today's culture. A recent Pew Research report found that, among 18 to 29-year-olds, over 90 percent use some form of social media while essentially 100 percent of young Americans (ages 18-29) have mobile phones, 94 percent of which are smartphones. 

High-volume hydraulic fracturing, colloquially called fracking, injects water, sand and chemicals under high pressure into petroleum-bearing rock formations to recover previously inaccessible oil and natural gas. While it was experimented with since the 1940s, it only became viable in the 1990s and early 2000s and it led to the current shale gas boom that started about 15 years ago. 

The Juno mission, designed to help scientists better understand Jupiter's origin and evolution, was launched in 2011 to map its gravitational and magnetic fields and probe the planet's deep, internal structure.

It's found some mysterious gravitational readings which experts infer mean Jupiter's core is less dense and more extended that expected. 

Jupiter began as a dense, rocky or icy planet that later gathered its thick atmosphere from the primordial disk of gas and dust that birthed our sun so what if the recent data could be explained by a giant impact that stirred Jupiter's core, mixing the dense contents of its core with less dense layers above. Like another planet.

An exploratory correlation claims that ozone levels can lead to lungs similar to the damage of someone who smokes a pack of cigarettes per day for three decades.

Microbial communities living in deep aquatic sediments have adapted to survive on really old food, according to a new study.

Learning how these microorganisms function on old, poor-quality food at a very slow pace could have future uses in biomedical applications such as a technology that could slow down cell metabolism in human organs so they can survive longer during a transplant process.

To better understand how these microorganisms access this food, researchers tested different types of peptidases—digestive enzymes that work to degrade proteins—in sediment cores from the White Oak River estuary in North Carolina.
