Lithium-ion batteries have been pivotal in powering modern technology, from mobile devices to electric vehicles. As demand for higher performance batteries grows, the focus has shifted from merely optimizing battery materials to rethinking the entire cell design and architecture.

In 2023, NASA-developed search and rescue technologies aided first responders in locating and saving 350 lives in the United States. Now, NASA is incorporating that same technology in astronaut missions.

More robust and more accurate positioning systems are needed to meet the demands of the global economy—and Australia is set to enjoy the benefits of its very own system.

It's called TinyLlama and it's taken the research world by storm because of how much power it packs.

A surgeon's hands could stretch 250 miles above Earth, should an upcoming test of a miniaturized surgical robot aboard the International Space Station prove successful.

The seamless integration of DOE's large-scale experimental facilities and powerful computing resources will help researchers keep pace with the ever-increasing influx of scientific data.

Countries worldwide have been introducing new policies aimed at mitigating climate change and reducing carbon emissions. Many of these interventions focus on deploying more sustainable systems to supply electricity on a large scale and introducing new technologies powered by electric power, such as electric vehicles and electrolyzers (i.e., electrically powered devices that can split water into hydrogen and oxygen atoms).

How does one frame per eight-and-a-half hours sound?

Virtual hand interactions are one of the most common and useful applications that virtual reality (VR) systems offer users. But, as a new Concordia-led study shows, personal preference remains an important factor in how the technology is applied, regardless of the effect on overall performance.

At present, the energy density of commercial lithium-ion batteries has been approaching the limit. Liquid lithium metal batteries (LMBs) are favored for their high-energy-density (>500 Wh kg−1), but commercialization is hampered by the flammability and explosiveness of the liquid solvent and the growth of Li dendrites.

Western Sydney University has released new research assessing how long it takes to get renewable energy projects planned, approved, built, and commissioned.

Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear.

There's always some truth in fiction, and now is about the time to get a step ahead of sci-fi dystopias and determine what the risk of machine sentience can be for humans.

Thermal decomposition is helping to green two major EU manufacturing industries.

A survey of nearly 3,000 machine learning experts on how our lives will be different in an AI world has been completed and the results are in.

It abseils from a height and swings around obstacles: Robot Avocado will one day maneuver through the canopy of the rainforest and collect data for researchers about this hard-to-reach habitat.

Researchers at ETH Zurich have recently developed artificial muscles for robot motion. Their solution offers several advantages over previous technologies: It can be used wherever robots need to be soft rather than rigid or where they need more sensitivity when interacting with their environment.

A research breakthrough in solar energy has propelled the development of the world's most efficient quantum dot (QD) solar cell, marking a significant leap toward the commercialization of next-generation solar cells. This cutting-edge QD solution and device have demonstrated exceptional performance, retaining their efficiency even after long-term storage.

Enhanced geothermal systems (EGSs) are human-made or enriched reservoirs within the Earth's subsurface, from which heat can be extracted to produce geothermal energy. The energy produced by these reservoirs could serve as an alternative source of electricity, helping to mitigate carbon emissions.
