​The old tales may be true: There is brimstone in the underworld, and lots of it. Brimstone, the biblical name for sulfur, is often found near hot springs and volcanic fissures on Earth’s surface (above). But scientists studying the formation of Earth’s core have shown that the lightweight nonmetal might also be present there in vast quantities, answering a question that has long troubled earth scientists: How could Earth’s core—predominantly made of the heavy elements iron and nickel—appear as light as it does when analyzed using seismic waves? 

Researchers report online today and in the July issue of Geochemical Perspectives Letters that the answer may be sulfur trapped deep within Earth. To come up with their results, the team compared the proportions of copper isotopes in ancient meteorites—the presumed building blocks of our planet—with the proportions of copper isotopes in rocks originating from the mantle—the deep layer of viscous rock beneath Earth’s crust.

About one third of Earth's largest groundwater basins are being rapidly depleted by human consumption, despite having little accurate data about how much water remains in them, according to two new studies led by the University of California, Irvine (UCI), using data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. This means that significant segments of Earth's population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings are published today in Water Resources Research.

A solid majority, 71% of Americans, believe the country “should do whatever it takes to protect the environment,” according to a 2014 poll by the Pew Research Center.

This strong public interest in our environment extends to urban living, prompting NerdWallet’s curiosity: Even though we all know that the city we live in influences our transportation and energy choices, how do environmental impacts differ across the U.S.?

We explored the data for the nation’s 150 largest cities to shed light on the best places for those seeking a green lifestyle and a healthy environment.

The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. Geological Survey. 

The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data. Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.

California’s water situation is beyond an emergency, according to Healdsburg resident Dave Howard. He and his sons returned from a “ski trip” in Northern California.

“The peaks are as bald as they normally are in August! Where’s the snow pack that’s supposed to be providing us water all summer? It’s zero folks. There is nothing there,” he said.

They proceeded on to Northstar ski resort. On a normal year there are more than a hundred runs. The temperatures are low enough and Northstar is making it’s own snow. Dave dropped his sons off, to go ahead.

“They did one run, then called me and said, ‘Dad we’re done. This is stupid. There is only one run worth doing and everyone is on it. This is not even worth spending any time on,” said Dave.

He added, “Northstar is scraping for their lives. Where’s their Spring skiing? It doesn’t exist. There in March, they’ve had a bad season already and its not going to get any better. There’s no hope on the horizon for those guys.”

In the past few weeks, giant cranes have unloaded some 1,500 solar panels onto the Knesset's (the Israeli parliament) roofs. These panels were created especially for the Knesset's solar field, which is laid out over 4,650 square meters of the Knesset roofs and will have an installed capacity of 450 kilowatts. The solar array, which cost the Knesset NIS 2.4 million, will create some 10% of the Knesset's electricity, and together with additional energy-saving measures, it will help reduce the Knesset's energy use by a third.

The solar array is expected to save the Knesset NIS 300,000 every year. It will operate according to the net-metering method, under which electric energy generated by an electric consumer from an eligible on-site generating facility and delivered to the local distribution facilities may be used to offset electric energy provided by the electric utility to the electric consumer during the applicable billing period. The Knesset's solar array will be the first of any national institution to operate according to this method. Director General of the Knesset, Mr. Ronen Plot, hopes that other government institutions and local authorities will follow suit and establish solar fields of their own.

As NASA's Dawn spacecraft closes in on Ceres, new images show the dwarf planet at 27 pixels across, about three times better than the calibration images taken in early December. These are the first in a series of images that will be taken for navigation purposes during the approach to Ceres.

Over the next several weeks, Dawn will deliver increasingly better and better images of the dwarf planet, leading up to the spacecraft's capture into orbit around Ceres on March 6. The images will continue to improve as the spacecraft spirals closer to the surface during its 16-month study of the dwarf planet.

Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually tends to reduce temperature variability.

Repeated cold snaps led to temperatures far below freezing across the eastern United States in the past two winters. Parts of the Niagara Falls froze, and ice floes formed on Lake Michigan. Such low temperatures had become rare in recent years. Pictures of icy, snow-covered cities made their way around the world, raising the question of whether climate change could be responsible for these extreme events

Zinc is an important part of the human diet. You get it in Cashews, spinach, beef, shrimp, flax seed, Oysters, garlic, lima beans peanuts, turkey, Salmon, Pork, Brown rice and other foods. These are not listed in any particular order.

Zinc, is an important mineral in human health, that appears to affect how the immune system responds to stimulation, especially inflammation, new research from Oregon State University shows.

Zinc deficiency could play a role in chronic diseases such as cardiovascular disease, cancer and diabetes   that involve inflammation. Such diseases often show up in older adults, who are more at risk for zinc deficiency.

“When you take away zinc, the cells that control inflammation appear to activate and respond differently; this causes the cells to promote more inflammation,” said Emily Ho, a professor and director of the Moore Family Center for Whole Grain Foods, Nutrition and Preventive Health in the OSU College of Public Health and Human Sciences, and lead author of the study.

Arctic sea ice shrank to the lowest winter extent ever recorded, according to data released today by the US-based National Snow and Ice Data Center. The record-low ice level follows earlier news that 2014 was the warmest year since record keeping began.
 
An unusually warm February in parts of Alaska and Russia contributed to the record ice low. The winter reach of Arctic ice decreased 1.1 million square kilometres compared to the average maximum from 1981 to 2010. This represents an area more than twice the size of Sweden.
 
"This is not a record to be proud of. Low sea ice can create a series of reactions that further threaten the Arctic and the rest of the globe," said Alexander Shestakov, Director, WWF Global Arctic Programme.
