Lithium-metal batteries, which contain anodes based on metallic lithium, are promising rechargeable batteries that could help to meet the growing demands of the electronics industry. These batteries have various advantages, including high energy density and fast charging times.

Michael Mann sued after two conservative writers liked his work to acts of infamous child molester Jerry Sandusky.

Scientists in Britain announced Thursday they had smashed a record for generating fusion energy in the final experiment using the Joint European Torus (JET) machines.

The Biden administration has frozen pending decisions on permit applications to export liquefied natural gas, or LNG, to countries other than U.S. free trade partners. During this pause, which will last for up to 15 months, the administration has pledged to take a "hard look" at economic, environmental and national security issues associated with exporting LNG.

With a lot of solar and wind power, energy storage, and advanced extreme weather impact modeling, Puerto Rico could achieve a 100% renewable power grid by 2050. These and other recommendations are the results of the "Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study" (PR100), announced Feb. 7.

Bulk acoustic wave (BAW) filters are used in various electronic devices, including smartphones, tablets, Wi-Fi routers, and communication systems to help produce smooth and reliable high-frequency radio signals for 5G communications. They are thus important in ensuring efficient communication and data transmission.

Elon Musk's team has implanted a powerful computer chip inside a living person's brain, a startling step toward a sci-fi future when we can steer computers with our thoughts.

Three researchers won a $700,000 prize for using artificial intelligence to read a 2,000-year-old scroll that was scorched in the eruption of Mount Vesuvius.

The warmest January on record was confirmed right after the world experienced its hottest year ever observed.

Next-generation electric vehicles could run on lithium metal batteries that go 500 to 700 miles on a single charge, twice the range of conventional lithium-ion batteries in EVs today.

In the future, modern machines should not only follow algorithms quickly and precisely, but also function intelligently—in other words, in a way that resembles the human brain. Scientists from Dortmund, Loughborough, Kiev and Nottingham have now developed a concept inspired by eyesight that could make future artificial intelligence much more compact and efficient.

A study published in the Journal of Field Robotics assessed the world's first unmanned machine designed for autonomous forestry operations.

Futuristic advancements in AI and health care stole the limelight at the tech extravaganza Consumer Electronics Show (CES) 2024. However, battery technology is the game-changer at the heart of these innovations, enabling greater power efficiency. Importantly, electric vehicles are where this technology is being applied most intensely.

Sewage sludge is the solid waste resulting from wastewater treatment. According to data from the Ministry for the Ecological Transition and the Demographic Challenge, 1.2 million tons of this waste were produced in Spain in 2021 alone, and its management is a growing problem.

When it comes to making fuel from plants, the first step has always been the hardest—breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon-neutral.

Imagine a coffee cup sitting on a table. Now, imagine a book partially obscuring the cup. As humans, we still know what the coffee cup is even though we can't see all of it. But a robot might be confused.

An Argonne team developing materials for solid-state batteries has taken an unexpected detour to investigate tiny short-circuits known as soft-shorts. Their insights will benefit battery researchers around the world.

The field of solar cells has witnessed exponential development over the past decades. Evaluating the performance of solar cells has been simple because all devices can be compared given a single metric, the efficiency, which is measured under standardized conditions.

The concept of solar geoengineering—blocking the sun's radiation to slow Earth's warming—is no longer just the realm of science fiction. In 2023, the U.S. government and the UN released reports on the topic. Whether or not solar geoengineering can save the world is up for debate, and Tony Harding, an assistant professor in the School of Public Policy, is contributing to the conversation.

Researchers at Kyushu University have found that Japan's current policy of stopping the sale of gas vehicles by 2035 and transitioning only to hybrids and electric vehicles may be insufficient to reduce the country's CO2 emissions and prevent it from reaching its decarbonization target goals. In fact, emissions may temporarily increase.
