Before the brewpub there was the brew cave.
In Israel's Raqefet Cave archaeologists recently reported traces of what could be the earliest known beer production 13,000 years ago.
The evidence comes from three stone mortars, analyzed in a 2018 Journal of Archaeological Science: Reports paper. After extracting residues from the rocks, the researchers identified plant molecules, including wheat or barley starches that appeared malted, mashed and fermented — the main ingredients and basic ...read more
Officials recently expanded the Port of Miami to allow in larger ships, impacting local coral colonies in the process. (Credit: Felix Mizioznikov/Shutterstock)
Coral reefs along the Florida coastline are struggling. Disease has been running rampant among colonies in recent years, and now researchers have found that a billion-dollar dredging project that wrapped up in 2015 killed off more than half of the coral population in the Port of Miami.
A study published May 24 in the journal Marin ...read more
The young star system includes two gas giants, shown here in an artist's illustration still forming and carving out gaps in the disk of material around their central star. (Credit: J. Olmsted/STScI)
While discoveries of exoplanets are commonplace these days, the most obvious detection method – directly taking a picture of a planet – remains one of the most challenging. And such images almost always reveal a single, giant planet orbiting far from its host star.
So researchers w ...read more
A small subset of the supernovas that Subaru discovered. Each set of three images shows (left to right) the sky before the supernova exploded, after, and the difference between the two images. (Credit: N. Yasuda et al.)
Before our solar system formed or our sun even began to shine, stars halfway across the cosmos were exploding in brilliant flashes of light called supernovas. The light from their death throes traveled for 8 billion light-years and arrived at Earth sometime in the past few ye ...read more
Two galaxies in the Fornax Cluster, NGC 1399 and NGC 1404, glow with X-rays when viewed with the Chandra X-ray Observatory. The bright points of light beyond the galaxies' outskirts may be binary stars that have been kicked out of their homes. (Credit: NASA/CXC/McGill University/X. Jin et al)
Astronomers have discovered evidence that some stars can be “kicked out” of their host galaxy, based on data collected by NASA’s Chandra X-Ray Observatory.
The stars in questio ...read more
