Cornell University archaeologist Sturt Manning hopes to settle one of modern archaeology’s longstanding disputes: the date of a volcanic eruption on the Greek island of Santorini, traditionally known as Thera.
Pittsburgh’s steel industry may be largely in the past, but its legacy lives on in city soils. New research led by Pitt geologists shows how historical coking and smelting dropped toxic metals in Pittsburgh’s soil, particularly in the eastern half of the city. With samples from 56 parks, cemeteries and other sites around the city collected by Carnegie Mellon University students and Jonathan Burgess from the Allegheny County Conservation District, the team was able to pinpoint some of those polluting factors. They recently published their results in the journal Environmental Research Communications.

Scientists have shed new light on the timing and likely cause of major volcanic events that occurred millions of years ago and caused such climatic and biological upheaval that they drove some of the most devastating extinction events in Earth’s history.
Curtin researchers and international collaborators using advanced satellite imagery have discovered an ancient reef-like landform ‘hidden’ in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater.
A little Martian dust appears to go a long way. A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket parts.
Tens of tons of extraterrestrial solid material collide with Earth daily. Most of this material is small enough that it burns up in the atmosphere, but some fragments are large enough to cause quite a predicament.
A few years ago, Rensselaer Polytechnic Institute’s Sasha Wagner, assistant professor of earth and environmental sciences, proved false what scientists had thought for years. Soot-like molecules that formed an ancient carbon pool deep in the Pacific Ocean did not, in fact, originate from wildfires on land.“We discovered that there was an isotopic mismatch,” Wagner said.

In its first year exploring Jezero Crater on Mars, the Perseverance rover collected rock samples that scientists anticipate will provide a long-awaited timeline for the planet’s geologic and water history.
Scientists on NASA’s Perseverance mission made a surprising discovery about the composition of rock in Jezero Crater, one that will help them get a better idea of when water existed on Mars, and ultimately, help them understand if the red planet was ever habitable to microbial life.
A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust goes through cycles, with periods of increased crust production roughly every 200 million years, corresponding to the solar system’s transit through the four primary spiral arms of the Milky Way galaxy.
New Curtin research has found evidence that Earth’s early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet’s formation on its head.
A new research center is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
The ‘Lithium-Ion Battery State’ may not have the same ring to it as ‘Battle-Born’ or ‘Silver State,’ but the reality is that Nevada could soon be a leader in the lithium battery supply chain – potentially giving the U.S. an edge in the arms race for the in-demand metal that’s the key to powering everything from your cell phone to electric vehicles.
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January created an initial wave 90 metres high – almost the height of the Statue of Liberty (93m)
Now, researchers say ubiquitous evidence for ongoing geological carbon sequestration in mantle rocks in the creeping sections of the SAF is one underlying cause of aseismic creep along a roughly 150 kilometer-long SAF segment between San Juan Bautista and Parkfield, California, and along several other fault segments.
KINGSTON, R.I. – Aug. 10, 2022 – Over the next three years, three University of Rhode Island researchers are hoping to broaden the scientific understanding of methane emission dynamics in ultramafic rock systems – work that one day may help answer the mystery of the existence of past or present microbial life on Mars.Dawn Cardace and Soni Pradhanang, associate professors of geosciences, and Serena Moseman-Valtierra, an associate professor of biological sciences, have been awarded a $735,000 grant by the NASA Established Program to Stimulate Competitive Research to study methane gas emissions at a site in northern California that has a rock system comparable to known sites on Mars.

A new study measured 38 years of change for glaciers in Kenai Fjords National Park, which lies south of Anchorage, and found that 13 of 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.
Researchers at the University of Bristol and Scottish Universities Environmental Research Centre have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth’s crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.
California’s McKinney Fire grew to become the state’s largest fire so far this year. The risk of wildfire is rising globally due to climate change. Below are some of the latest articles that have been added to the Wildfires channel on Newswise.
Heinrich Events or, more accurately, Heinrich Layers, are recurrent conspicuous sediment layers, usually ten to 15 centimeters thick, with very coarse rock components that interrupt the otherwise fine-grained oceanic deposits in the North Atlantic.
A professor emeritus at Tohoku University has unearthed evidence pointing to a strong relationship between the magnitude of mass extinctions and global temperature changes in geologic times.
More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
The latest technology to study glaciers fits in a backpack and can be carried up steep mountains. University of Oregon researchers have developed a portable tool that uses lasers to measure the composition of glacial ice, data that can help determine how fast that ice is melting. The instrument can be used to study glaciers in remote wilderness areas, like those in Oregon’s Cascade Mountains. And it can help verify satellite data collected about bigger glaciers, like those in Greenland and Antarctica.
For the first time, scientists have shown that glaciers in the tropical Andes mountains have been in sync with polar ice extent in Antarctica and the Arctic for nearly a million years. A study, published July 13 in Nature, is the first to show that the effects of greenhouse gases and other drivers of the Earth’s temperature are impacting glaciers in the Southern Hemisphere at the same pacing as ice sheets in the north.
Astronomy postdoc Valerie Payré is on an international team that discovered the origin of the martian meteorite known as Black Beauty, one of the most-studied meteorites in the world.
