New research has answered the mystery of how the Crystal Palace in London, which at the time was the world's largest building, was constructed in only 190 days.

Sharing infrastructure for transporting and storing captured carbon dioxide (CO2) emissions across multiple industrial facilities could cut costs by more than 60% and reduce pipeline buildout by more than 75% in Louisiana, according to new research led by engineers at the Andlinger Center for Energy and the Environment.

Researchers have found that AI large language models, like GPT-4, are better at predicting what comes next than what came before in a sentence. This "Arrow of Time" effect could reshape our understanding of the structure of natural language, and the way these models understand it.

New Zealand's current electricity supply crisis requires immediate solutions.

Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences have developed a novel autofocus method that harnesses the power of deep learning to dynamically select regions of interest in grayscale images. The study was published in the journal Sensors.

If you care about the environment, think twice about using AI. Generative artificial intelligence uses 30 times more energy than a traditional search engine, warns researcher Sasha Luccioni, on a mission to raise awareness about the environmental impact of the hot new technology.

Generative artificial intelligence (AI) has notoriously struggled to create consistent images, often getting details like fingers and facial symmetry wrong. Moreover, these models can completely fail when prompted to generate images at different image sizes and resolutions.

Tropical Storm Ileana made landfall on the coast of the Mexican state of Sinaloa.

佛罗里达州基韦斯特西北部的 Splashdown 将结束一项以首次非政府民用太空行走为重点的任务。

The widespread use of artificial intelligence (AI) tools designed to process large amounts of data has increased the need for better performing memory devices. The data storage solutions that could help to meet the computational demands of AI include so-called high-bandwidth memories, technologies that can increase the memory bandwidth of computer processors, speeding up the transfer of data and reducing power consumption.

随着全球对储能解决方案的需求不断增长，当前锂离子电池的局限性，例如安全问题和高成本，推动了替代技术的探索。水性锌离子电池（AZIB）因其固有的安全性、成本效益和环境可持续性而成为一种有前途的候选者。然而，锌枝晶生长等挑战继续阻碍其广泛采用。由于这些挑战，迫切需要深入研究创新解决方案以提高 AZIB 性能。

EPFL scientist Sascha Nick has outlined a completely new scenario for what housing and neighborhoods might look like in Switzerland in the coming decades. His recommendations would put the country on track to meet its net-zero target while supporting the well-being of residents and communities.

U-Net，一种原本用于医疗用途的卷积神经网络（CNN），有可能在海洋遥感领域掀起波澜

Existing global energy projections underestimate the impact of climate change on urban heating and cooling systems by roughly 50% by 2099 if greenhouse gas emissions remain high, researchers report. This disparity could profoundly affect critical sustainable energy planning for the future.

Low-orbit satellites could soon offer millions of people worldwide access to high-speed communications, but the satellites' potential has been stymied by a technological limitation—their antenna arrays can only manage one user at a time.

随着全球对锂离子电池的需求迅速耗尽原材料储备，专家们正在寻找安全、实惠且可靠的可充电电池替代品。

Most rechargeable batteries that power portable devices, such as toys, handheld vacuums and e-bikes, use lithium-ion technology. But these batteries can have short lifetimes and may catch fire when damaged.

A technology that can directly charge a battery from a smartphone screen has emerged. A research team affiliated with UNIST has unveiled a method of supplying energy directly from glass of buildings, cars, and mobile devices through transparent solar cells. The study is published in PNAS.

The interface between electrodes and electrolytes largely contributes to the efficiency with which batteries convert energy. In recent years, many efforts aimed at developing better performing batteries have focused on tailoring the electrode/electrolyte interface to boost the energy density of rechargeable batteries, particularly lithium-metal batteries (LMBs).
