Lithium-ion batteries have a lot of advantages. They charge quickly, have a high energy density, and can be repeatedly charged and discharged.

As artificial intelligence (AI) technologies become more embedded into our everyday lives and business operations, their high energy demands and environmental impacts call for a more sustainable approach to building algorithms—the sets of instructions used to inform this technology.

Fish fins and insect wings are amazing pieces of natural engineering capable of efficiently moving their owners through water or air. People creating machines to swim or fly have long looked to animals as their models, designing airplanes with wings and boats with fin-shaped rudders. Over the past decades, researchers at Caltech and elsewhere have been exploring bioinspired engineering to see if other natural forms of motion might inform mechanical engineering.

Many people now work partly or permanently from home. This saves petrol because they no longer have to drive to the office—which is good for the energy transition. Or not. Because at home, they consume even more energy for heating and cooking, and video calls also consume extra energy in the data centers of Microsoft, Zoom and the like. Does digitalization now save energy or are we just blowing more CO2 into the atmosphere?

The future deployment of AIs and robots in our everyday work and life, from fully automated vehicles, to delivery robots, and AI assistants, could either be done by making increasingly capable agents that can do many tasks, or simpler more narrow agents that are designed for specific tasks.

People use large language models for a huge array of tasks, from translating an article to identifying financial fraud. However, despite the incredible capabilities and versatility of these models, they sometimes generate inaccurate responses.

The effective integration of extremely thin insulating layers with two-dimensional (2D) semiconductors could enable the fabrication of 2D transistors with an electrical capacitance comparable to SiO2 with thicknesses below 1-nm. These transistors could, in turn, help to boost the performance and reduce the power consumption of electronic devices.

Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, along with collaborators from leading international institutions, have introduced an innovative cathode homogenization strategy for all-solid-state lithium batteries (ASLBs).

Most wind turbines face the wind—and there is a good reason for that. Since the 1980s, wind turbine developers have been using what is called the "Danish concept" for their designs—three blades, positioned upwind (i.e., facing the wind), that are engineered to keep facing the wind to maximize energy production.

Connecting multiple AIs together and putting them in the body of a robot, similar to Star Wars' C-3PO or R2-D2, is the most likely way AI will become as intelligent as humans, according to a scientist from the University of Sheffield.

To measure the flow of air through a jet engine, researchers traditionally place sensors where air enters and exits.

While large language models (LLMs) have demonstrated remarkable capabilities in extracting data and generating connected responses, there are real questions about how these artificial intelligence (AI) models reach their answers. At stake are the potential for unwanted bias or the generation of nonsensical or inaccurate "hallucinations," both of which can lead to false data.

Starry Studio's live-service survival game is thoroughly enjoyable despite an awkward clashing of systems.

A call for collaboration to define the language in all AI related spaces, with a focus on 'diverse intelligent systems' that include AI (Artificial Intelligence), LLMs (Large Language Models) and biological intelligences is underway. The study was led by Cortical Labs—the biological computing startup that created "Dishbrain"—and brought together scientists, ethicists and researchers from the United Kingdoms, Canada, U.S., the EU, Australia and Singapore. Together they have proposed a pathway forward to unify the language in the rapidly growing and controversial area.

Have you ever wondered how AI chatbots make decisions? This question arose in a classroom at the Cornell Tech campus and prompted a new study from Cornell SC Johnson College of Business that delves into the differences between decision-making processes in human and artificial intelligence.

Solar energy is one of humanity's best bets against the ongoing energy crises and climate change. With solar panels becoming an attractive energy solution, both in open fields and on rooftops in urban areas, scientists are diligently working to advance existing photovoltaic technologies and achieve new heights in sustainability. While many types of photovoltaic materials are being studied, perovskites are undoubtedly among the most promising due to their potential for low-cost production and higher efficiency.

The combined thermal degradation of olive pomace and plastic waste by pyrolysis increases the effectiveness of the process and generates new value-added products, such as biofuels, according to a study by the University of Córdoba.

Researchers have criticized billionaire Elon Musk for promising that his brain implant technology could eventually provide patients with vision superior to normal human sight.

As artificial intelligence increasingly impacts our daily lives, researchers in the University at Buffalo School of Management have developed a new framework to transform AI chatbots into more intuitive, human-like conversation partners.

A Brigham Young University professor has figured out a way to shave critical years off the complicated design and licensing processes for modern nuclear reactors: artificial intelligence.
