A growing portion of Americans who are struggling to pay for their household energy live in the South and Southwest, reflecting a climate-driven shift away from heating needs and toward air conditioning use, an MIT study finds.

For long periods of its history, artificial intelligence has lurked in the hinterland of science, often unloved and unfunded—but two Nobel prizes in one week suggest its time in the sunshine has finally arrived.

Industries such as chemical manufacturing, fertilizer production and hydrogen generation could significantly cut emissions, improve efficiency and lower costs using a newly developed electrified reactor as an alternative to high-temperature industrial processes.

Researchers have created a new modeling tool that can be used to help develop ocean-based hydrokinetic energy projects. The tool can be used both to help design more robust marine hydrokinetic technologies and to inform risk assessments that are essential for securing financing and permitting of commercial projects. The paper, "Bayesian Modeling and Mechanical Simulations for Fragility Curve Estimation of The Mooring System of Marine Hydrokinetic Devices," is published in the journal Applied Ocean Research.

As pedestrian fatalities in the United States reach a 40-year high, a novel approach to measuring crosswalk lengths across entire cities could provide urban planners with crucial data to improve safety interventions.

British-Canadian Geoffrey Hinton and American John Hopfield won the Nobel physics prize on Tuesday for their pioneering work on the foundations of artificial intelligence, with both sounding the alarm over the technology they helped bring to life.

A new paper from the University of California San Diego details how China faces numerous political, economic and technological obstacles as it tries to transition away from coal—the country's primary energy source—while balancing the need to combat climate change with the need for energy security.

MIT engineers have built a new desalination system that runs with the rhythms of the sun. The researchers report details of the new system in a paper appearing in Nature Water.

Geoffrey Hinton, known as the Godfather of AI, and physicist John Hopfield won the Nobel physics prize on Tuesday for their pioneering work on the foundations of artificial intelligence.

1884 年，海洋工程師查爾斯·帕森 (Charles Parson) 使用煤炭為他的突破性發明——多級蒸汽渦輪機提供動力，從而發電。這場技術革命標誌著全球發電和消費的新曙光。如今，人類不斷增長的電力和電力需求需要更有效率的渦輪機和環保燃料。

The Nobel Prize in Physics was awarded to two scientists on Tuesday for discoveries that laid the groundwork for the artificial intelligence used by hugely popular tools such as ChatGPT.

Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it's quicker than existing methods and capable of making more complex objects.

The National Renewable Energy Laboratory (NREL) has developed a first-of-its-kind tool that enables hydropower operators and developers to estimate the greenhouse gas emissions associated with building and operating closed-loop pumped storage hydropower (PSH) facilities.

The 2024 Nobel Prize in Physics has been awarded to scientists John Hopfield and Geoffrey Hinton "for foundational discoveries and inventions that enable machine learning with artificial neural networks."

Researchers from Tampere University in Finland and Anhui Jianzhu University in China have made a significant breakthrough in soft robotics. Their study introduces the first toroidal, light-driven micro-robot that can move autonomously in viscous liquids, such as mucus. This innovation marks a major step forward in developing micro-robots capable of navigating complex environments, with promising applications in fields such as medicine and environmental monitoring.

Engineers have worked out how to give robots complex instructions without electricity for the first time, which could free up more space in the robotic 'brain' for them to 'think.'

Marine energy devices have the potential to deliver gigantic amounts of power―if they can survive the ocean's punishing conditions. Innovative system designs are needed to convert wave movements into electricity, but the sea is vast and complex, and deployment in these remote locations is expensive.

Entire houses can be built from clay or excavated earth. The material is cheap, abundant, and sustainable as it does not require cement. However, existing building methods are very labor-intensive, slow and therefore expensive.

As Hurricane Milton intensified on its path toward Florida's Gulf Coast, the strength of the system increased the severity of the storm surge forecast.

South Africa is immersed in a "just energy transition" from a fossil fuel-based energy system to a cleaner, low-carbon energy system. This new system will be based primarily on renewable energy, such as solar, wind and green hydrogen.
