NASA has created a new digital modeling tool for aeronautical engineers to innovate new aircraft designs, building on decades of experience using highly advanced computer code for aviation.

The race is on to develop a new generation of liquid fuels that are activated by sunlight, and Yale researchers are helping to lead the way.

Lithium-ion batteries are integral to numerous applications, ranging from everyday electronics to electric vehicles. Despite their widespread use, these batteries pose safety risks due to the flammable liquid electrolytes they typically contain, which can lead to dangerous fires and explosions.

A team of AI researchers at AWS AI Labs, Amazon, has found that most, if not all, publicly available Large Language Models (LLMs) can be easily tricked into revealing dangerous or unethical information.

When Peter Gorr got his first solar roof in 2011, he didn't know what to expect.

Two-terminal devices are electronic components connected to electrical circuits via two electrical terminals. Although these components are the key building blocks of most existing devices, they can limit a system's performance and functions.

When cycling or walking, you have chosen some of the most climate-friendly modes of transport. But they are not always useful for going to Ikea, the recycling center, or doing the weekly groceries, and this is where most of us grab the car.

While the demand for climate-warming fuels like petroleum and diesel is expected to peak before 2030, the global energy demand for alternative fuels to power vehicles to transport people, goods, and services will grow rapidly in the coming years. Researchers at the National Renewable Energy Laboratory (NREL) recently studied whether a new type of biofuel, produced by genetically engineered bacteria, could be part of the solution.

Enabling machines to communicate like humans is a long-term goal of open-domain dialogue generation. To achieve this goal, more and more studies on dialogue generation focus on the key factor, emotion. The empathetic dialogue system aims to recognize user's emotion and situation, then generates responses accordingly.

Researchers Indrek Must and Kadri-Ann Valdur of the Institute of Technology of the University of Tartu have created a robot leg modeled after the leg of a cucumber spider. The soft robot created in cooperation with the Italian Institute of Technology could, in the future, move where humans cannot.

NASA has taken the next step toward verifying the airworthiness for its quiet supersonic X-59 aircraft with the completion of a milestone review that will allow it to progress toward flight.

A team of experts, including Monash University researchers, has developed a new technique to implement quantum-safe digital signatures twenty times faster, resulting in speedier and safer online transactions than ever before.

They found that care in hospitals with higher surgery team sex diversity was linked with better post-operative outcomes for patients.

After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.

Video games are big business. The value of the global market is pushing the US$200 billion mark (£158 billion): bigger than the music industry and Hollywood combined. But the gaming industry has also been facing challenges. The market is shrinking from its peak at the height of the pandemic, and there has been a rash of layoffs and studio closures.

Engineers from University of Glasgow and colleagues from the U.K. and Australia are behind a research breakthrough in a developing form of wireless communications could help precisely pinpoint the locations of people and objects indoors.

The COVID-19 pandemic changed life in many ways, including stopping nearly all commercial flights. At the Toronto Pearson International Airport, airplane traffic dropped by 80% in the first few months of lockdown. For a nearby group of researchers, this presented a unique opportunity.

Chemical and material engineering professor, Adnan Khan, has spent the past 15 years focusing his research on developing sustainable technologies aimed at decarbonizing our energy systems. "This is the most important challenge we face today. We owe this to our future generations," he says.

Oscar Wilde once said that sarcasm was the lowest form of wit, but the highest form of intelligence. Perhaps that is due to how difficult it is to use and understand. Sarcasm is notoriously tricky to convey through text—even in person, it can be easily misinterpreted. The subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools.

Researchers at the Department of Energy's Oak Ridge National Laboratory are developing battery technologies to fight climate change in two ways, by expanding the use of renewable energy and capturing airborne carbon dioxide.
