Though 2023 was a relatively slow year for new wind power deployment in the United States, the industry continues to see growth, solid performance, expanding supply chains, and attractive prices, according to a report prepared for the U.S. Department of Energy (DOE) by Lawrence Berkeley National Laboratory (Berkeley Lab).

In the ever-evolving field of robotics, a groundbreaking approach has emerged, revolutionizing how robots perceive, navigate, and interact with their environments. This new frontier, known as brain-inspired navigation technology, integrates insights from neuroscience into robotics, offering enhanced capabilities and efficiency.

Your early morning run could soon help harvest enough electricity to power your wearable devices, thanks to a new nanotechnology developed at the University of Surrey.

A research team has developed a computer vision technique that can perform dichotomous image segmentation, high-resolution salient object detection, and concealed object detection in the same framework. Their novel bilateral reference framework (BiRefNet) is able to capture tiny-pixel features and holds potential for a wide range of practical computer vision applications.

A team of AI researchers and computer scientists at the University of Alberta has found that current artificial networks used with deep-learning systems lose their ability to learn during extended training on new data. In their study, reported in the journal Nature, the group found a way to overcome these problems with plasticity in both supervised and reinforcement learning AI systems, allowing them to continue to learn.

Transistors, the building blocks of integrated circuits, face growing challenges as their size decreases. Developing transistors that use novel operating principles has become crucial to enhancing circuit performance.

Health assessment body NICE says the benefits “are too small to justify the costs”.

Un intento de utilizar un robot extensible para retirar un fragmento de combustible derretido de un reactor destrozado en la central nuclear japonesa de Fukushima Daiichi, afectada por el tsunami, fue suspendido el jueves debido a un problema técnico.

The Shiveluch volcano spewed an ash column as high as 5 mils above sea level and released a gush of lava, TASS reported Sunday morning.

In a new study assessing how climate change might alter hydropower generation across the continental United States, researchers show that except for some parts of the Southwest, hydropower generation is expected to rise in the future.

An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.

Las olas de calor occidentales de este verano plantean el espectro de los cortes de energía rotativos de los últimos años y la demanda de electricidad sin precedentes en la región.Si las empresas de servicios públicos de la zona ampliaran los esquemas actuales para compartir electricidad, podrían reducir los riesgos de cortes hasta en un 40%, según una nueva investigación del Programa de Política Climática y Energética del Instituto Stanford Woods para el Medio Ambiente.

Un equipo de investigación multidisciplinario con sede en China y Brasil ha utilizado un robot parecido a un perro e inteligencia artificial para crear una nueva forma de encontrar nidos de hormigas bravas.Publicado en la revista Pest Management Science, el estudio destaca cómo un robot "CyberDog" integrado con un modelo de IA puede automatizar la identificación y el control de las hormigas rojas de fuego importadas (RIFA), una plaga destructiva a nivel mundial.

El fosfato de hierro y litio es uno de los materiales más importantes para las baterías de los coches eléctricos, los sistemas estacionarios de almacenamiento de energía y las herramientas.Tiene una larga vida útil, es comparativamente económico y no tiende a arder espontáneamente.La densidad energética también está avanzando.Sin embargo, los expertos todavía se preguntan por qué las baterías de fosfato de hierro y litio reducen en la práctica su capacidad teórica de almacenamiento de electricidad hasta en un 25%.

A new technology can extract lithium from brines at an estimated cost of under 40% that of today's dominant extraction method, and at just a fourth of lithium's current market price. The new technology would also be much more reliable and sustainable in its use of water, chemicals, and land than today's technology, according to a study published in Matter by Stanford University researchers.

West Virginia University roboticists are working on an alternative path to robot autonomy in Loopy, a "multicellular robot" composed of a ring of individual interconnected robot cells.

Scientific discovery is one of the most sophisticated human activities. First, scientists must understand the existing knowledge and identify a significant gap. Next, they must formulate a research question and design and conduct an experiment in pursuit of an answer. Then, they must analyze and interpret the results of the experiment, which may raise yet another research question.

The findings are from India's historic Chandrayaan-3 mission that landed on the Moon's south pole.

Researchers at the School of Engineering of the Hong Kong University of Science and Technology (HKUST) have developed an eco-friendly refrigeration device with record-breaking cooling performance, setting the stage for transforming industries reliant on cooling and reducing global energy use.

A team of AI researchers and computer scientists from Cornell University, the University of Washington and the Allen Institute for Artificial Intelligence has developed a benchmarking tool called WILDHALLUCINATIONS to evaluate the factuality of multiple large language models (LLMs). The group has published a paper describing the factors that went into creating their tool on the arXiv preprint server.
