University of Toronto engineering researchers have designed a new way to recycle steel that has the potential to decarbonize a range of manufacturing industries and usher in a circular steel economy.

A year after an experimental submersible imploded en route to the Titanic, unanswered questions linger—with no immediate answers.

June 5 is World Environment Day. According to China's Ministry of Ecology and Environment, the theme for World Environment Day in 2024 is

As an extreme heat wave is gripping parts of South Asia since mid-May, the past week became the most brutal period with the mercury soaring to 50 C in some parts of India and Pakistan and resulting in multiple deaths, stirring a public concern over whether China will bake under a blistering heat wave this summer.

China entered its general flood season on Saturday, with the flooding in the southern region already in full swing, according to the Ministry of Water Resources (MWR), while an expert told the Global Times on Sunday that this year's flood season in the southern part of China started earlier than usual.

Chinese scientists for the first time obtained continuous observation data of the tropospheric atmosphere over the Qinghai-Xizang Plateau, which would support the prediction of severe weather events and studying weather processes and environmental changes over plateau, the Global Times learned from the Tibetan Plateau Research (ITP), Chinese Academy of Sciences.

Ships sail on the Three Gorges Reservoir as its water level drops to 145 meters on June 6, 2024, completing the pre-flood season lowering task four days ahead of schedule and officially transitioning to flood season management. The Yangtze River Basin is currently in the main flood season from June to August. Meteorological forecasts indicate above-average precipitation in the basin for June this year. Photo: VCG

As China announces the inclusion of, for the first time in history, payload specialists from Hong Kong and Macao special administrative regions (SARs) into the country's taikonaut pool, experts and local media said there is high hope that they will play key roles in China's future manned lunar landing around 2030, highlighting the significance that central government attaches to the SARs' scientific research capabilities and strong support for youth development in these regions.

A novel 256-element wirelessly powered transceiver array for non-line-of-sight 5G communication, featuring efficient wireless power transmission and high-power conversion efficiency, has been designed by scientists at Tokyo Tech.

A new way to teach artificial intelligence (AI) to understand human line drawings—even from non-artists—has been developed by a team from the University of Surrey and Stanford University.

Organic solar cells (OSCs) are a key part of the global effort to end our reliance on fossil fuels. Over the past few decades, new advances in technology have led to steady improvements in their efficiency and affordability.

The first generation of lithium-ion batteries for electric vehicles has been a remarkable success story. Yet, the question arises: What changes to battery materials will spur further advances to extend driving range and lower costs?

There's no guaranteed path to safety as artificial intelligence advances, Geoffrey Hinton, AI pioneer, warns. He shares his thoughts on AI's benefits and dangers with Scott Pelley.

Iquitos, Peru cannot be reached by road because of its surrounding jungles and waters, leading to an unwelcome guest: Mosquitoes.

The debate that will steer the future of consciousness — and us.

Energy researchers have been trying to understand the implications of a transition to fully renewable energy for decades. Some past studies suggested that technologies to generate energy from renewable energy sources, such as solar panels and wind turbines, might not generate as much net energy (i.e., the energy remaining after accounting for the energy consumed to generate power) as their long-standing fossil fuel-reliant counterparts.

In a study published in Advanced Energy Materials, researchers have constructed a hydrogel electrolyte formula by using ClO4- anions and polyacrylamide chains to anchor water molecules, while glucose molecules preferentially regulate Zn2+ solvation.

Adding nitrogen to concrete could significantly reduce global levels of potentially harmful nitrogen oxides (NOx) created by the construction industry in developing towns and cities, a new study reveals.

In advancing sustainable waste management and CO2 sequestration, researchers have crafted reactors that mineralize carbon dioxide with fly ash particles. This avant-garde technique is set to offer a sustainable and lasting solution to the pressing issue of greenhouse gas emissions, repurposing an industrial by-product in the process.

In a breakthrough for lithium recovery technologies, researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, together with collaborators, have developed a crystalline carbon nitride membrane that could transform the lithium extraction industry.
