A recent study conducted by the Science Unit of Lingnan University in Hong Kong (LU) shows that concentrations of fine particulate matter (PM2.5) from incense burning both inside and outside temples could be 6 times and 4 times of the recommended levels respectively. In addition, the more temples there are in the same district, the higher the respiratory mortality rate. The research team suggests that alternative measures, such as installation of automatic mist sprayers to reduce smoke dispersion, as well as using incense made with non-toxic substances to minimise health risks to worshippers and neighbours, should be considered.

Around 650 million years ago, the Earth entered into the Marinoan glaciation that saw the entire planet freeze. The “Snowball Earth” impeded the evolution of life. But as it warmed, biotic life began to flourish. A research team from Tohoku University has analyzed rock samples from China to tell us more about this transition.

Researchers at Ehime University have reported the sound velocity of MgSiO3 Majorite garnet up to the pressure of 18 Gigapascals and temperature up to 2,000 Kelvins. Their results lead to understanding of the mineral composition of the Earth’s mantle transition zone (MTZ), which has not been fully elucidated yet. This study suggests that a mechanical mixture of slab and mantle rocks, rather than equilibrated rocks, is more likely to explain seismological observations throughout the MTZ.

A collaboration between Osaka City University and Setsunan University sheds light on the effect urbanization has on the flesh fly species Sarcophaga similis. Through a series of laboratory and in-field experiments, scientists show that an increase in nighttime illumination and temperature, two of the major characteristics of urbanization, can postpone S. similis hibernation anywhere from 3 weeks to a month.

Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water.

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

Scientists have uncovered a summertime climate pattern in and around the Arctic that could drive co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America.

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.
