Imagine tires that charge a vehicle as it drives, streetlights powered by the rumble of traffic, or skyscrapers that generate electricity as the buildings naturally sway and shudder.

Offshore wind could have prevented the Fukushima disaster, according to a review of wind energy led by the University of Surrey.

The ocean has a hidden talent, honed over millennia: the ability to capture and store vast quantities of carbon dioxide, a key driver of climate change. However, the ocean's natural carbon capture cycles, which take hundreds of thousands of years, cannot keep pace with human-generated carbon emissions. The global shipping industry alone contributes roughly 3% of global CO2 emissions.

Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed a sustainable and controllable strategy to manipulate interfacial heat transfer, paving the way for improving the performance of eco-friendly cooling in various applications such as electronics, buildings and solar panels.

在應對氣候變遷的競賽中，科學家正在開發將二氧化碳 (CO2) 轉化為有價值的燃料和化學品的技術。這些創新有助於遏制溫室氣體排放，同時提供低碳燃料來為我們的未來提供動力。隨著美國轉向低碳經濟，我們需要環保燃料來為飛機、船和火車等難以電氣化的車輛提供動力。科學家正在開發將二氧化碳轉化為燃料的技術。然而，這種轉化需要大量的能量和水。

A new study from the University of Toronto's Department of Civil & Mineral Engineering suggests that large-scale adoption of electric vehicles (EVs) could lead to significant population-level health benefits.

A new analysis from University of Toronto Engineering researchers leverages machine learning to help answer a thorny question: where should new protected bike lanes be placed to provide maximum benefit?

The development of affordable and highly performing sensors can have crucial implications for robotics research, as it could improve perception to help boost robot manipulation and navigation. In recent years, engineers have introduced a wide range of advanced touch sensor devices, which can improve the ability of robots to detect tactile signals, using the information they gather to guide their actions.

Researchers have developed a new way to automatically detect hate speech on social media platforms more accurately and consistently using a new multi-task learning (MTL) model; a type of machine learning model that works across multiple datasets.

In nature, flying animals sense coming changes in their surroundings, including the onset of sudden turbulence, and quickly adjust to stay safe. Engineers who design aircraft would like to give their vehicles the same ability to predict incoming disturbances and respond appropriately.

The ambitious mission won't actually look for life, but it should find out if the presumed ocean provides a habitable environment.

Nearly two weeks after Hurricane Helene downed power lines and washed out roads all over North Carolina's mountains, the constant din of a gas-powered generator is getting to be too much for Bobby Renfro.

The author of the bestseller "Sapiens: A Brief History of Humankind" returns with an examination of the power of intelligence to shape and control civilizations throughout history, and how artificial intelligence may change society, economics and politics.

Using laser scans and GPS cameras, accurate down to one inch, the U.S. Geological Survey has so far mapped more than 600 landslides caused by Hurricane Helene.

人工智慧推理技術公司 BitEnergy AI 的工程師團隊報告了一種將人工智慧應用的能源需求減少 95% 的方法。該小組發表了一篇論文，描述了他們在 arXiv 預印本伺服器上的新技術。

Just published research in Nature Sustainability shows that building a renewable energy system for a telescope in Chile's isolated Atacama Desert could also cover 66% of a nearby community's energy needs, giving hope for win-win development around other remote infrastructure projects.

Hours after the artificial intelligence pioneer Geoffrey Hinton won a Nobel Prize in physics, he drove a rented car to Google's California headquarters to celebrate.

Widespread coverage of building rooftops with conventional photovoltaic solar panels may increase temperatures on hot days and lower them at night, says new modeling.

A solar cell developed by RIKEN physicists can be stretched without greatly affecting its ability to convert light into electricity. It is thus promising for powering the next generation of wearable electronics.

The 2024 Nobel Prizes in physics and chemistry have given us a glimpse of the future of science. Artificial intelligence (AI) was central to the discoveries honored by both awards. You have to wonder what Alfred Nobel, who founded the prizes, would think of it all.
