Distribution-type membrane reactors are expected to be highly promising for carbon dioxide methanation reaction. In a recent breakthrough, a group of scientists from Shibaura Institute of Technology, Japan, has demonstrated the efficacy of these reactors and also examined the effect of membrane properties on reaction parameters. The present findings are a significant step towards a greener, cleaner, and more sustainable future.

A recent study published in National Science Review has introduced a policy-specific assessment framework featuring a novel Synergy Index, designed to uncover how air pollution control and carbon mitigation can move in harmony or fall out of step. Drawing on China’s on-road transportation sector as a case study, the research quantifies both the realized and untapped synergies in reducing greenhouse gases (GHGs) and improving air quality. The findings paint a compelling picture: from 2010 to 2020, China’s on-road transportation emission control policies achieved lower GHG emissions, cleaner air, and substantial public health benefits. However, behind this progress lies an unexpected finding showing that policy synergies have been weakening, highlighting the urgency of robust structural transitions to maintain long-term carbon and air-pollution co-control, to advance a sustainable pathway toward the Sustainable Development Goals, and to fullfil the newly announced NDC target.

Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have discovered that extended periods of high stress lead to iron deficiency and stunted growth in wheat crops. Experiments show reducing iron deficiency with a synthetic organic molecule called PDMA results in better growth and healthier plants. These findings are good news for farmers and consumers alike and could lead to treatments in the field that improve wheat production during prolonged periods of heat. The study was published in the scientific journal Nature Communications.

Greenhouse gas emissions from many wastewater treatment plants may be more than twice as large as previously thought. This is shown in a new study from Linköping University, Sweden, where the researchers used drones with specially manufactured sensors to measure methane and nitrous oxide emissions.

After two years of use, lithium-ion battery electric vehicles (BEVs) result in a reduction in cumulative carbon dioxide (CO₂) emissions compared to fossil-based internal combustion engine (ICE) vehicles, according to a new study published this week in the open-access journal PLOS Climate by Pankaj Sadavarte of Duke University, US, and colleagues.

UC Davis scientists have discovered a new species of trapdoor spider in California's coastal sand dunes.

A comprehensive new report (https://academic.oup.com/bioscience/article-lookup/doi/10.1093/biosci/biaf149) published in the journal BioScience reveals that Earth's climate crisis is accelerating at an alarming rate, with 22 of 34 planetary vital signs now at record levels. The study, co-led by Dr. William J. Ripple of Oregon State University and Dr. Christopher Wolf of Terrestrial Ecosystems Research Associates, presents stark evidence that Earth is approaching climate chaos.
