The relationships among CAW, heatwaves, wildfires, and pollution. Anomalous anticyclones characterize the atmospheric circulation that develops concomitantly over the three remote regions around the summertime Arctic (July and August). The authors named it the circum-Arctic wave (CAW) pattern. These anticyclones induce warm and dry conditions from the surface to the mid-troposphere. The CAW can drive heatwaves and wildfires; wildfire smoke also emits aerosols that increase PM2.5 in and around the Arctic

Carbon degassed from planetary mantles by volcanic activity plays an important role in the planetary surface environment. However, how the carbon content in the Earth’s mantle was established is still poorly understood. Here we show that the mantle of planetary embryos may have been nearly saturated with carbon by new high-pressure experiments and pointed out that the carbon solubility of magma is very consistent with the estimated carbon contents in terrestrial and lunar mantles.

Tomohiro Mochizuki tracks down viruses inside single-cell organisms thriving in boiling hot springs. His fieldwork is conducted in relatively extreme environments and, despite the significance of his investigations, he doesn’t need many fancy gadgets back at his lab at Japan’s Earth-Life Science Institute (ELSI). ARN asked Mochizuki about his virus-hunting exploits and what they involve.

“By looking at substances in volcanos, lakes and hotsprings, you can start to see the ecosystems that existed billions of years ago,” says Mayuko Nakagawa, a microbiologist and specially-appointed assistant professor at the Earth-Life Science Institute (ELSI) based at the Tokyo Institute of Technology, Japan. She analyses components left by microorganisms with colleagues from various disciplines, while as a lab manager, she looks after cutting-edge equipment and visitors from different countries.

A stable isotope of helium, 3He, was produced by the Big Bang and a remnant of the solar nebula. 3He is included in ocean island basalts, such as in Hawaiian volcanos, indicating it has been stored somewhere in the deep Earth and carried up to the surface in upwelling plumes. New computer simulations demonstrate that even in small amounts, helium can be dissolved in liquid iron at ultrahigh-pressure conditions, suggesting that there is a reservoir in the Earth’s core.

A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person’s risk, they do indicate an infrastructure of protection that persists despite how densely populated a person’s district might be.

“The earth is suffering from several ‘diseases’: global warming, ocean acidification, habitat loss, etc. If any of these diseases remains uncured, other diseases will accelerate and cause new ones to appear, hence putting humanity’s well-being in danger,” said Associate Professor Masahiko Fujii. For this reason, the research staff of the Faculty of Environmental Earth Science keeps on assessing the current global environmental issues and promoting renewable energy sources as a possible solution.

Figure 1: The drawing shows a clam with its foot extending deep into the sediment to gain access to hydrogen sulfide. The foot and mantle of the clam are red due to the presence of haemoglobin for gas transport in the blood, which is an adaptation to the low-oxygen environment. (Drawn by HKBU student Hu Juntong)

A study led by scientists at Hong Kong Baptist University (HKBU) has decoded the genomes of the deep-sea clam (Archivesica marissinica) and the chemoautotrophic bacteria (Candidatus Vesicomyosocius marissinica) that live in its gill epithelium cells. Through analysis of their genomic structures and profiling of their gene expression patterns, the research team revealed that symbiosis between the two partners enables the clams to thrive in extreme deep-sea environments.
