Stone Age humans once sheltered in lava tube caves
  + stars: | 2024-05-08 | by ( Mindy Weisberger | ) edition.cnn.com   time to read: +7 min
Beginning in the Stone Age, Neolithic herders descended into and occupied these vast tunnels, known as lava tubes, archaeologists have discovered. Umm Jirsan spans nearly 1 mile (1.5 kilometers), with passages that are up to 39 feet (12 meters) tall and as much as 148 feet (45 meters) wide. The researchers enter Umm Jirsan, the longest lava tube system in the region. Animal carvingsIn another tunnel near Umm Jirsan, the researchers found 16 panels of engraved rock art. “Collectively, the archaeological findings at the site and in the surrounding landscape paint a picture of recurrent use of the Umm Jirsan Lava Tube over millennia,” Stewart said.

CNN —Earth’s magnetic field plays a key role in making our planet habitable. However, Earth’s magnetic field almost collapsed 591 million years ago, and this change, paradoxically, may have played a pivotal role in the blossoming of complex life, new research has found. The discovery of the sustained weakening of Earth’s magnetic field also helped resolve an enduring geological mystery about when Earth’s solid inner core formed. Shuhai Xiao/Virginia TechUncovering the magnetic field’s near collapseThe intensity of Earth’s magnetic field is known to fluctuate over time, and crystals preserved in rock contain tiny magnetic particles that lock in a record of the intensity of Earth’s magnetic field. The research on the intensity of Earth’s magnetic field suggests that the age of Earth’s inner core is on the younger end of that timescale, solidifying after 565 million years ago and allowing Earth’s magnetic shield to bounce back.

NASA released photos of parts of Dubai and Abu Dhabi before and after the United Arab Emirates was hit by record rainfall last week that caused dangerous floods and paralyzed much of the country. The images, taken by NASA Earth Observatory on Friday using Landsat data from the U.S. Geological Survey, show large patches of water all over the desert and urban landscape of the UAE where previously there was none – almost looking as if small lakes had appeared. "Some areas remained flooded on April 19, when Landsat 9 passed over the region for the first time since the storms," NASA wrote on its Earth Observatory website. Flash floods that formed on April 16 led to water engulfing cars, in some areas fully submerging them, leading hundreds of drivers to abandon their vehicles on roads to escape the rising water levels. The normally dry desert country in the Gulf was pummeled with roughly a year's worth of rain in less than a day, more than it has ever seen in a single storm since records for the UAE began in 1949.

And the day-to-day weather conditions near Mount Ruang – things like temperature, clouds and rain – probably won’t be influenced by the volcano for long, Huey told CNN. Mount Ruang, a 2,400-foot (725-meter) stratovolcano on Ruang Island in Indonesia’s North Sulawesi province, has erupted at least seven times since Tuesday night, the country’s volcanology agency said. Mount Ruang spewed lava and and ash on April 17, seen from Sitaro, North Sulawesi. Once in the stratosphere, sulfur dioxide and water vapor combine to form sulfuric acid aerosols that create a layer of hazy droplets, according to UCAR. In 1991, Mount Pinatubo – another stratovolcano – erupted in the Philippines and produced the largest sulfur dioxide cloud ever measured.

CNN —Unprecedented, torrential rainfall plunged parts of the United Arab Emirates underwater last week, bringing life to a standstill in Dubai and elsewhere. NASA NASA Images taken over the Jebel Ali area, located on the southern outskirts of Dubai, capture the area before and after historic flooding. The flooding shown is in the southernmost portion of Dubai, but the city’s highly urbanized central hub isn’t captured. The torrential rain was associated with a larger storm system last week traversing the Arabian Peninsula and moving across the Gulf of Oman. A warmer atmosphere is able to soak up more moisture like a towel and then ring it out in the form of torrential rainfall.

A deep basin called Sputnik Planitia, which makes up the “left lobe” of the heart, is home to much of Pluto’s nitrogen ice. The New Horizons spacecraft took an image of Pluto's heart on July 14, 2015. Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/NASAThrough new research on Sputnik Planitia, an international team of scientists has determined that a cataclysmic event created the heart. The teardrop shape of Sputnik Planitia is a result of the frigidity of Pluto’s core, as well as the relatively low velocity of the impact itself, the team found. The researchers believe that the new theory regarding Pluto’s heart could shed more light on how the mysterious dwarf planet formed.

CNN —Indonesian authorities on Wednesday ordered hundreds of villagers to evacuate following multiple eruptions of a remote island volcano, raising fears it could collapse into the sea and trigger a tsunami. Mount Ruang, a 725-meter (2,400-foot) conical stratovolcano on Ruang Island, North Sulawesi, has erupted at least five times since Tuesday night, spewing fiery lava and ash plumes thousands of feet into the sky, the country’s volcanology agency said. Mount Ruang spewed hot lava and ash columns into the night sky on April 17, 2024, as seen from Sitaro, North Sulawesi. Ruang Island is home to about 800 residents, who have temporarily relocated to neighboring Tagulandang Island, according to authorities. Indonesia, a Southeast Asian archipelago of 270 million people, has over 120 active volcanoes – more than anywhere else in the world.

Signage is seen at the headquarters of the United States Environmental Protection Agency (EPA) in Washington, D.C., U.S., May 10, 2021. The Environmental Protection Agency, EPA, released long-awaited regulations Wednesday on some toxic "forever chemicals" found in drinking water. The bonds are incredibly strong and take a very long time to break down, earning them the nickname "forever chemicals." The EPA's new final rule sets limits on 5 individual PFAS: PFOA, PFOS, PFNA, PFHxS, and HFPO-DA (also known as GenX Chemicals.) The EPA also set a Hazard Index level for PFAS when two or more of four are mixed: PFNA, PFHxS, HFPO-DA, and PFBS.

“It would be about 25 years before all the PFAS leave your body.”Testing your waterWhat can consumers do right now to limit the levels of PFAS in their drinking water? Filtering your waterIf PFAS levels are concerning, consumers can purchase an under-the-counter water filter for their tap. “The water filters that are most effective for PFAS are reverse osmosis filters, which are more expensive, about in the $200 range,” Andrews said. Reverse osmosis filters can remove a wide range of contaminants, including dissolved solids, by forcing water through various filters. PFAS in food and your homeDrinking water is not the only way PFAS enters the bloodstream.

CNN —Potentially toxic chemicals called PFAS (perfluoroalkyl and polyfluoroalkyl substances) are found in surface and groundwaters around the world at levels much higher than many international regulators allow, a new study found. Groundwater can be contaminated by PFAS from food and consumer products added to landfills as well as from manufacturing facilities. Public concern led to a commitment by manufacturers in 2008 to phase out use of PFOA and PFOS, two of the most widely used chemicals. Generally PFAS concentrations are higher in urban areas or areas that used PFAS products extensively, O’Connell said, but it is also leached into the environment in ways that may not be obvious. “Another example is that PFAS used to be used in ski wax, so pristine environments, where people ski, have PFAS in their waters and soils,” he said.

Some climate activists accuse the industry of simply investing in carbon capture as way to extend the use of oil and gas. The technology typically uses chemical absorption to capture carbon dioxide emitted from the chimney of an industrial plant. "The economic viability of carbon capture and sequestration is a challenge today because the cost of building most plants in order to capture carbon dioxide are very significant," the executive said. About two-thirds of the industry's carbon dioxide emissions come from chemical reactions that occur when breaking down limestone. SLB this month announced a nearly $400 million investment in Aker Carbon Capture, a pure-play carbon capture company based in Norway, in an effort to accelerate deployment of the technology at commercial scale.

A 4.8-magnitude earthquake sent tremors from Philadelphia to Boston this morning, rattling New York City skyscrapers and surprising many East Coasters. The earthquake struck at 10:23 a.m. Eastern, with an epicenter near Whitehouse Station, N.J. — about 40 miles west of New York City — according to the United States Geological Survey. It was the largest quake within 250 miles of Manhattan in more than 30 years, and the third largest since the data began in 1957. New Yorkers are more familiar with much smaller tremors, which usually go unnoticed in a city full of rumbles. The city is also filled with old brick buildings, and officials said they remained concerned about the aftereffects of the quake.

The 4.8-magnitude earthquake on the East Coast Friday came from ancient dormant faults. The East Coast, however, is located in the middle of a plate and doesn't experience much of that movement. NOAAInstead, East Coast quakes come from stress that builds up on those ancient fault lines. The glaciers heavily weighed down and compressed the northern part of the East Coast. Though that weight has been lifted for more than 10,000 years, the Earth's crust is still rising back to its former shape.

Inside the Museum of Contemporary Art in Denver, little pieces of Antarctica were melting: cross-sections of an ice core from the continent’s Newall Glacier, each one about the size of a beverage coaster and encased in a vacuum-sealed plastic bag. The artist Gala Porras-Kim watched approvingly during a visit in March, pointing out the air pockets that had started to form. “The ice cores are an archive of ancient air, because the air gets stuck in the layers of ice,” she said, pointing at the display during an interview at the museum. This particular core, which Porras-Kim had obtained from the National Science Foundation’s Ice Core Facility in nearby Lakewood, Colo., contained ice that had formed some 10,000 years ago, around the beginning of the Holocene period, in geological terms. “The ancient air will get released into this room — a reunion of this old air with the new air, mixing together,” she said, describing it as an “organic de-accession process.”
