A 3,700-year-old palatial cellar packed with jars once filled with a wine-like brew has been discovered at an archaeological site in northern Israel, a team of researchers announced Friday.
The cellar is perhaps the oldest of its type ever discovered and the wine was anything but ordinary. Spiked with juniper berries, cedar oil, honey and tree resins, it was likely the good stuff pulled from the cellar for grand, royal banquets where resident rulers and perhaps their trading partners washed down a feast of wild cattle with an intoxicating swill.

A newly discovered volcano rumbling beneath nearly a mile of ice in Antarctica will almost certainly erupt at some point in the future, according to a new study. Such an event could accelerate the flow of ice into the sea and push up the already rising global sea levels.
When the volcano will blow is unknown, “but it is quite likely” to happen, Amanda Lough, a graduate student in seismology at Washington University in St. Louis, Mo., told NBC News.

As water becomes increasingly scarce on our ever more crowded and warming planet, brewers of beer are racing to secure a steady supply of their most prized ingredient by using less of it.
“Without water, there is no beer,” Kim Marotta, the sustainability director for MillerCoors, the Chicago-based joint venture of international brewing giants SABMiller and Molson Coors, told NBC News.
Like many in the brewing industry, MillerCoors understands that access to water of the quantity and quality it needs to grow barley and hops and brew beer is no longer a guarantee as population growth, water pollution and climate change threaten water resources.

The rivers of water pumped into and out of the ground during the production of natural gas, oil and geothermal energy are causing the Earth to shake more frequently in areas where these industrial activities are soaring, according to a series of studies published today.
While the gas extraction process known as hydraulic fracturing (aka “fracking”) causes some small quakes, it’s the disposal of wastewater following that process — and many others relating to energy production — that lead to the largest tremors.
“Fortunately, there have been no deaths and damage has been limited to date, but it is obviously of concern to people as we think about the future of the energy economy,” William Ellsworth, a seismologist with the United States Geological Survey in Menlo Park, Calif., told NBC News.

Oyster hatcheries are dropping the equivalent of Tums and other antacids into water to make it easier for naked mollusk larvae to build their shells. The remedy is working, for now, to keep hatcheries in business and oyster bars well stocked with the slimy delicacies, a hatchery scientist said.
Heartburn for the shellfish industry comes from ocean waters turning ever more corrosive as they absorb a fraction of the carbon dioxide humans are pumping into the atmosphere. The acidification, in turn, makes it harder for oyster larvae to build their shells.
The hatcheries’ antacid, sodium carbonate, makes the water less acidic and “raises the amount of carbonate in the water, which is what the shellfish are using,” Benoit Eudeline, the chief hatchery scientist at Taylor Shellfish Company in Quilcene, Wash., told NBC News.

Anyone hoping to spice up their gluten-free diet need look only at the billions of beady-eyed, shrimp-size cicadas currently emerging from the ground in the eastern United States.
“They definitely would be gluten free … they do not feed on wheat,” said Gene Kritsky, a biologist and cicada expert at the College of Mount St. Joseph in Cincinnati, Ohio. The bugs are also high in protein, low in fat, and low in carbohydrates, he added.
Members of Brood II, one of the largest groups of periodical cicadas, have been crawling out of the ground and carpeting trees from North Carolina to Connecticut since early May. By July, they will be gone—not to be heard from again for 17 years.

In cloudy, drizzly Seattle, Denis Hayes, the environmental activist who organized the first Earth Day in 1970, is pulling the wraps off a six-story office building that generates all of its electricity via an oversized rooftop array of solar panels.
A sun-powered building in Seattle is “formidable,” Hayes told NBC News, but the Bullitt Center project aims to show it is possible in a visible, tangible manner that, in turn, makes an impact on the often invisible, slow-motion challenge of global climate change.
“When this whole [Earth Day] thing got launched in 1970, we had people walking around with gas masks and smokestacks were pouring out enormous impenetrable clouds of black smoke,” said Hayes, who is now president of the Bullitt Foundation, which supports environmental causes.
