锂离子电池是可充电电池领域的重量级人物。随着电动汽车在世界上变得越来越普遍，利用丰富的锰 (Mn) 的高能、低成本电池可以成为商业化并在汽车行业中使用的可持续选择。

Last week, quantum computers were added to Australia's Defense and Strategic Goods List of controlled items facing export restrictions. That's because quantum technologies—which may soon provide huge advances in computing, communication and sensing—are rapidly growing in strategic importance.

Automatic bug assignment has been well studied in the past decade. As textual bug reports usually describe the buggy phenomena and potential causes, engineers highly depend on these reports to fix bugs. Researchers heavily depend on the textual content in the bug reports to locate the buggy files. However, noises in texts bring adverse impacts to automatic bug assignments unexpectedly, mainly due to insufficiency of classical Natural Language Processing (NLP) techniques.

洛桑联邦理工学院的研究人员开发了下一代微型脑机接口，能够在微型硅芯片上直接进行大脑到文本的通信。

For the past decade, disordered rock salt has been studied as a potential breakthrough cathode material for use in lithium-ion batteries and a key to creating low-cost, high-energy storage for everything from cell phones to electric vehicles to renewable energy storage.

最近旨在开发更先进电池技术的努力在很大程度上集中在设计新型阴极材料上。这是因为现有的阴极在高电压下表现不佳，并且会导致电池容量的快速损失。

The Boeing Starliner astronauts stranded in space for nearly three months are going to have to be there a little longer ... 'cause they're not going to be earthbound until next year.

A team of scientists from the Department of Energy's SLAC National Accelerator Laboratory has uncovered new information about the photoelectric effect, a phenomenon first described by Einstein over a century ago. Their method provides a new tool to study electron-electron interactions, which are fundamental to many technologies, including semiconductors and solar cells.

Over the past couple of decades, computer scientists have developed a wide range of deep neural networks (DNNs) designed to tackle various real-world tasks. While some of these models have proved to be highly effective, some studies found that they can be unfair, meaning that their performance may vary based on the data they were trained on and even the hardware platforms they were deployed on.

Brown widow spiders are venomous, but their bites are considered much less dangerous than other venomous spiders.

Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) see a realistic path forward to the manufacture of bio-derivable wind blades that can be chemically recycled and the components reused, ending the practice of old blades winding up in landfills at the end of their useful life.

Hybrid perovskites have great potential for use in advanced electronic devices like solar cells and LEDs. However, one major issue holding them back is that they don't last as long as needed for widespread commercial use. As these materials age, their performance drops, which is a big problem for both researchers and companies.

A range of technical and policy approaches are being considered to mitigate global climate change. Whether and how these approaches are prioritized or abandoned often depends directly on public approval.

As climate change creates hotter, drier conditions, we are seeing longer fire seasons with larger, more frequent wildfires. In recent years, catastrophic wildfires have destroyed homes and infrastructure, caused devastating losses in lives and livelihoods of people living in affected areas, and damaged wildland resources and the economy. We need new solutions to fight wildfires and protect areas from damage.

您最近发送的电子邮件可能是使用经过验证的方法进行加密的，该方法依赖于这样的想法：即使是最快的计算机也无法有效地将巨大的数字分解为因子。

由于庞大的数据中心将推高本已庞大的能源需求，新加坡这个小城邦正在向澳大利亚的沙漠和马来西亚的热带雨林寻求清洁能源。

减少锅炉和其他工业设备等小型燃烧系统的碳排放，是建设更加可持续、碳中和的未来的关键一步。锅炉广泛应用于各个行业的基本过程，如供暖、蒸汽产生和发电，这使其成为温室气体排放的重要贡献者。

The center of Tropical Storm Hone could pass near or south of Hawaii's Big Island this weekend, forecasters said.

在大型数据集上训练深度学习模型对于其成功至关重要；然而，这些数据集通常包含标签噪声，这会显着降低测试数据集的分类性能。

过去十年人工智能（AI）的快速发展极大增强了可穿戴设备处理复杂数据的能力。其中，人工智能算法的一大类机器学习及其重要分支深度学习是本次人工智能浪潮的主推力。
