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.

The university has unveiled a few more details of its new Green Goals Initiative, which includes developing green technology and promoting resilience and social Innovation. It also hopes to achieve carbon neutrality on campus by 2040.

Using neurons directly reprogrammed from tissues of stranded whales to assess brain health A research team of the Center for Marine Environmental Studies (CMES) of Ehime University, Japan succeeded for the first time in direct reprogramming of whale somatic cells to neuronal cells, and conducted a neurotoxicity test using these cells. Exposure to a metabolite (4′OH-CB72) of polychlorinated biphenyls, ubiquitous environmental pollutants, caused apoptosis in the reprogrammed neurons. Transcriptome analysis of 4′OH-CB72-treated whale neurons showed altered expressions of genes associated with oxidative phosphorylation, chromatin degradation, axonal transport, and neurodegenerative diseases.

The State Key Laboratory of Marine Pollution (SKLMP) at City University of Hong Kong (CityU) has been endorsed by the United Nations (UN) to initiate a ten-year "Global Estuaries Monitoring (GEM)" Programme (www.globalestuaries.org) to collect and study environmental pollutants in the estuaries of major cities around the globe so as to formulate a long-term policy of promoting clean estuaries.

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.

Scientists develop a 3D-printed pressure sensor embedded with a temperature sensor from conductive carbon-based composites.

Scientists in Singapore are calling for revisions in planned hydropower expansions in light of the rapidly decreasing cost of solar photovoltaic systems

A new study monitored satellite images to obtain sea discoloration data as a novel indicator in detecting if an underwater volcano’s eruption is imminent.

ARN's July newsletter features research about a promising treatment candidate to reverse dementia, a newly discovered climate pattern, using starch in tiny energy devices, exploring earth Earth ecosystems and the photo of the month.

A team of leading climate social scientists, including a chair professor at The Education University of Hong Kong (EdUHK), argues that influential studies that attempt to quantify different countries’ “fair shares” of climate action have put forward a biased and oversimplified view of what is primarily a political and ethical discussion.

Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake.

Japanese and Zambian scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well.

Magnetic layers interact with sunlight differently, creating a temperature gradient that generates electricity day and night.

Researchers from The University of Tokyo Institute of Industrial Science develop a flood forecasting system that could help protect people and property during typhoons

Paris, June 11 – Spending on science worldwide increased (+19%) between 2014 and 2018, as did the number of scientists (+13.7%). This trend has been further boosted by the COVID crisis, according to UNESCO’s new Science Report, The Race against Time for Smarter Development.

ARN's June newsletter features research on a hands-off approach to discipline, better robot hand design, nucleosomes and marine biodiversity, plus the latest Beyond the Journal and a feature from the ARN magazine.

Research Covers Humans’ Historical Adaptation to Climate Change

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.

Scientists have shown that the population of the Yakushima sika deer has declined due to natural factors, suggesting that the population can be regulated without culling.

Researchers at The University of Tokyo Institute of Industrial Science repurpose food waste to build materials with a bending strength comparable to concrete and that still taste good

The Asia Research News magazine brings you fascinating research stories from diverse voices in environment, technology, materials, medicine, space and social sciences. The 2021 edition is out now.

Scientists from Hokkaido University have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea – regions where species richness, community stability and climate stability are high.

From biomemory to implants, researchers are looking for ways to make more eco-friendly electronic components.

Invented by Professor Ho Wing-kei at the Department of Science and Environmental Studies of The Education University of Hong Kong (EdUHK), the novel graphitic carbon nitride photocatalyst provides an innovative way for environmental purification. Compared to the traditional photocatalyst such as titanium dioxide, which can only be activated by UV light, and has a relatively low effectiveness in air pollutant degradation, the newly developed photocatalyst can utilise visible light (daylight or indoor light) as the light source for photocatalytic reactions.

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.

火山や湖、温泉の物質からは数十億年前に存在した微生物の生態系が見えてくると語るのは、東京工業大学・地球生命研究所（ELSI）の中川麻悠子特任助教。異分野の研究者たちと共に微生物の作り出した成分を解析する傍ら、ラボマネージャーとして国内外の訪問者サポートや最先端の機材の管理などを行っている。

A new study on frogs shows gene flow and population structure should be considered to determine if morphologically similar and genetically distinct animals comprise separate species.

Ice is melting at a surprisingly fast rate underneath Shirase Glacier Tongue in East Antarctica due to the continuing influx of warm seawater into the Lützow-Holm Bay.
