Astronomy fans figuring out where and what time to see the April 8, 2024, total solar eclipse can check out maps showing the path of totality.

Recently, artificial intelligence (AI) has been cast as a problem in the urgent, international effort to tackle climate change. As AI plays a greater role in our lives, it will need enormous amounts of computing power and data storage.

The 2024 total solar eclipse is approaching. Here's how to check your solar glasses and tell if they're safe to use.

The quake didn’t cause any major damage.

As technology and science advance at breakneck speed, a Swiss group is already looking beyond AI to the next big potential technological disrupters.

The Structures Technical Discipline Team (TDT) was involved in numerous investigations this past year, but composites, fracture mechanics, and pressure vessels dominate the list. All three of these specialties are important to composite overwrapped pressure vessels (COPV).

Several air taxi companies are using a NASA-developed computer software tool to predict aircraft noise and aerodynamic performance. This tool allows manufacturers working in fields related to NASA's Advanced Air Mobility mission to see early in the aircraft development process how design elements like propellors or wings would perform. This saves the industry time and money when making potential design modifications.

A team of researchers has unveiled a time series machine learning technique designed to address data drift challenges. This innovative approach, led by Professor Sungil Kim and Professor Dongyoung Lim from the Department of Industrial Engineering and the Artificial Intelligence Graduate School at UNIST, effectively handles irregular sampling intervals and missing values in real-world time series data, offering a robust solution for ensuring optimal performance in artificial intelligence (AI) models.

A research team from the Empirical Research Support (ERS) at CISPA Helmholtz Center for Information Security has conducted a systematic comparison of the most popular transcription services. The comparison involved 11 providers of manual as well as AI-based transcriptions.

A new study highlights the potential for Texas to become a global leader in the development of a robust hydrogen economy.

It was a 4.7 magnitude quake.

Connecting cheap, clean energy from renewables comes with a hidden cost and challenge: building 5,000 kilometers of new transmission lines this decade, and another 5,000km after that. This sounds like a lot, but 5,000km is only around 10% of the existing grid network, and unlocks more than 32 gigawatts of new clean energy capacity by 2030.

Honeybees are too valuable to go extinct. Not every species will be so fortunate.

A team of materials scientists and engineers from Donghua University, in China, and the National University of Singapore, has developed a type of fiber that does not rely on chips or batteries to convert visual signals to digital transmissions as it interacts with the human body.

Ancient ocean oxygenation timeline –a key to understand the planet’s history – is revealed by Hebrew University earth scientists.

China has extended its manufacturing domination to clean energy industries in recent years, alongside a global push for climate change action, but that is starting to worry the United States, Europe and others.

American drivers have long been accustomed to quickly filling up at a gas station with plenty of fuel available, and electric vehicle drivers want their pit stops to mimic this experience. Driver uncertainty about access to charging during long trips remains a barrier to broader EV adoption, even as the U.S. strives to combat climate change by converting more drivers.

Researchers in Japan have effectively developed a diverse range of personality traits in dialogue AI using a large-scale language model (LLM). Using the prisoner's dilemma from game theory, Professor Takaya Arita and Associate Professor Reiji Suzuki from Nagoya University's Graduate School of Informatics' team created a framework for evolving AI agents that mimics human behavior by switching between selfish and cooperative actions, adapting its strategies through evolutionary processes. Their findings were published in Scientific Reports.

Medium- and heavy-duty vehicles (MHDVs) account for just 5% of vehicles on the road in the United States, yet they are responsible for 21% of transportation-related greenhouse gas emissions. Reducing MHDV emissions is vital to mitigating the effects of climate change and improving air quality. Zero-emission vehicles (ZEVs)—such as battery electric vehicles (EVs) and hydrogen fuel cell electric vehicles (FCEVs)—offer a solution.

New research suggests that materials commonly overlooked in computer chip design actually play an important role in information processing, a discovery that could lead to faster and more efficient electronics.
