Oregon experiments find that electrical sparks are possible on Mars
Friction caused by dry Martian dust particles making contact with each other may produce electrical discharge at the surface and in the planet's atmosphere, according University of Oregon researchers. However, such sparks are likely to be small and pose little danger to robotic or human missions to the red planet, they report in the journal Icarus. (2021-02-19)

Russian scientists significantly improved coal-burning efficiency
A team of Russian scientists from NUST MISIS, Tomsk Polytechnic University (TPU) and Boreskov Institute of Catalysis has suggested a new approach to modifying the combustion behavior of coal.

Pyroclasts protect the paintings of Pompeii buried but damage them when they are unearthed
A study conducted by the UPV/EHU's IBeA group shows that pyroclasts may be putting the conservation of the paintings of Pompeii at risk. Specifically, the ions leached from these materials and the underground ion-rich waters from the volcanic rocks may be causing the salts in the paintings to crystallise. In addition, the use of fluorine as a marker is proposed to monitor in situ the extent of the damage sustained by the murals. (2020-11-30)

Offshore submarine freshwater discovery raises hopes for islands worldwide
Twice as much freshwater is stored offshore of Hawai'i Island than previously thought, revealed a University of Hawai'i study with important implications for volcanic islands around the world. An extensive reservoir of freshwater within the submarine southern flank of the Hualālai aquifer was mapped by researchers with Hawai'i EPSCoR 'Ike Wai project, showing a way in which substantial volumes of freshwater are transported from onshore to offshore submarine aquifers along the coast of Hawai'i Island. (2020-11-25)

Electromagnetic imaging reveals freshwater cache off Hawai'ian coast
Pointing toward a much-needed future reservoir of freshwater for the island of Hawai'i in the face of climate-driven drought, electromagnetic images of the island have revealed multilayered basalt, ash and soil formations that serve as a previously unknown conduit to move freshwater offshore to the submarine flank of the island.

Ancient zircon minerals from Mars reveal the elusive internal structure of the red planet
Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, researchers from the University of Copenhagen have shown that a population of these crystals were sourced from the deep interior of Mars. If the researchers are correct, it means that the young zircons contain information about the deep, inaccessible interior of Mars, which provides insights into the internal structure of the planet.

Chemical clues in leaves can reveal ash tree resistance to deadly disease
Naturally occurring compounds in ash leaves could be linked to susceptibility of individual trees to the fungal disease ash dieback (ADB). But selecting trees with lower levels of these compounds and breeding for resistance could leave the UK ash tree population open to attack from invading insect pests in the future, according to scientists at the University of Warwick. (2020-11-11)

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)

Radioactive elements may be crucial to the habitability of rocky planets
The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth's magnetic field protects the planet from solar winds and cosmic rays. (2020-11-10)
