The authors suggest their sensor could be used for diagnosis of respiratory diseases. (2021-01-12)

Understanding origins of Arizona's Sunset Crater eruption of 1,000 years ago
ASU School of Earth and Space Exploration scientist Amanda Clarke and her team have been working to solve the mysterious root cause of the Sunset Crater eruption and any lessons learned to better understand the threats similar volcanoes may pose around the world today. But as to why it erupted, that has remained a mystery, until now. Clarke's group is among the first to show the importance of carbon dioxide in volcanic eruptions. (2021-01-11)

Reawakened geyser does not foretell Yellowstone volcanic eruptions, study shows
Geyser eruptions, like volcanic eruptions, are a mystery, so the reactivation of Steamboat Geyser in Yellowstone in 2018 provided an opportunity to explore why geysers turn off and on, and what determines their periodicity. A team led by UC Berkeley researchers found little evidence of magma moving below the geyser, meaning no sign of imminent hydrothermal eruptions, but did discover a relationship between the height of the column and the depth of the water reservoir. (2021-01-04)

Dopamine surge reveals how even for mice, 'there's no place like home'
''There's no place like home,'' has its roots deep in the brain. Using fiber photometry, scientists are the first to show that home evokes a surge of dopamine in mice that mimics the response to a dose of cocaine. The study demonstrates how dopamine rises rapidly in mice moved from a simple recording chamber to their home cage, but less so when they return to a cage not quite like the one they knew. (2020-11-12)

Large volcanic eruption caused the largest mass extinction
Researchers in Japan, the US and China say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life. Their research looked at two discrete eruption events: one that was previously unknown to researchers, and the other that resulted in large swaths of terrestrial and marine life going extinct. (2020-11-10)

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists from the University of Geneva has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below. (2020-11-05)

Scientists grow carbon nanotube forest much longer than any other
Carbon nanotube (CNT) forests are a solution to scaling up the production of CNTs, which are becoming a staple in many industries. However, even the best catalyst used to grow these forests deteriorates quickly, capping possible forest length at ~2 cm. Now, scientists from Japan have proposed a way to ensure longer catalyst lifetime and higher growth rate, creating a CNT forest that is a record seven times longer than any existing CNT array. (2020-11-04)

Squid jet propulsion can enhance design of underwater robots, vehicles
Squids use a form of jet propulsion that is not well understood, especially when it comes to their hydrodynamics under turbulent flow conditions. Discovering their secrets can help create new designs for bioinspired underwater robots, so researchers are exploring the fundamental mechanism. They describe their numerical study in Physics of Fluids; among their discoveries, they found that thrust production and efficiency are underestimated within laminar, or nonturbulent, flows.

Deep magma facilitates the movement of tectonic plates
A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists from the LGL-TPE (CNRS/ENS de Lyon/UCBL1) have recently discovered. Their new model takes into account not only the velocity of seismic waves but also the way in which they are attenuated by the medium they pass through. The velocity of tectonic plates near the surface is thus directly correlated with the quantity of magma present. (2020-10-21)

Deep learning artificial intelligence keeps an eye on volcano movements
RADAR satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, Penn State researchers have used artificial intelligence (AI) to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest. (2020-10-15)
