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.

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.

Using data from the 1995 Kobe Earthquake, researchers have uncovered a better understand about radon concentration in the atmosphere before and after earthquakes. The findings move us closer to being able to predict when large earthquakes will occur.

A team of scientists has, for the first time, identified landfalls of tropical cyclones (TCs) in Japan for the period from 1877 to 2019; this knowledge will help prepare for future TC disasters.

Twenty-two scholars of The Education University of Hong Kong (EdUHK) were named on Stanford University’s list of the top two per cent most-cited scientists in various disciplines, including President Professor Stephen Cheung Yan-leung, Chair Professor of Public Policy; Professor Jim Chi-yung, Research Chair Professor of Geography & Environmental Science; and Professor Wong Ming-hung, Advisor (Environmental Science).
25 Feb 2021
Medical staff and researchers from Tohoku University and Fukushima Medical University conducted a collaborative, multifaceted training program for healthcare workers to better prepare them for disasters. The training incorporated a wide range of subjects such as data analysis, cultural revitalization in the wake of disasters, and post-disaster psychological and physical well-being.

Fujitsu, Tohoku University, and Tokyo University have unveiled a new AI model that can accurately predict tsunami flooding in coastal areas within seconds. The new technology, which harnessed the power of the world’s fastest supercomputer Fugaku, will bolster authorities ability to effectively direct evacuation orders.

Lingnan University in Hong Kong (LU) has recently established a publicly accessible Natural History Collection (the Collection) of specimens of local amphibians and reptiles to document Hong Kong’s biodiversity, and for research, conservation and education purposes.

A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle boundary beneath central Greenland that melts the ice from below.

Researchers at Ehime University have recently measured the propagation speed of ultrasonic waves in an aluminum-rich hydrous mineral called Al-phase D at pressure conditions relevant to the Earth’s deep mantle. Their results suggest that seismic shear anomalies observed locally beneath subduction zones may reveal the presence of hydrous minerals in the uppermost lower mantle, which would have important implications for the Earth’s interior because hydrogen affects considerably the physical and chemical properties of mantle minerals.

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

A team of researchers has discovered more about the grain-scale fluid connectivity beneath the earth's surface, shedding new light on fluid circulation and seismic velocity anomalies in subduction zones.

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.

Far too little is known about the long-term dynamics of the abundance of most macro-organism species. We used sedimentary DNA technology to quantify marine fish DNA abundance in sediment sequences spanning the last 300 years. This study first shows the existence of fish DNA in the sequences and proves that fish abundance can be tracked using sedimentary DNA, highlighting the utility of sedimentary DNA for researchers to acquire lengthy records of macro-organism species abundance.

A joint-study led by a team of marine ecologists from City University of Hong Kong (CityU) has found that the eco-engineered tiles can increase habitat complexity on seawalls in Hong Kong, thereby effectively enhancing the marine biodiversity. The Hong Kong study is part of a global research project on the relationship between habitat complexity and marine biodiversity on human-built marine structures.
