As we navigate the complex landscape of energy transition, a promising solution is emerging from an often overlooked source: our existing oil and gas infrastructure. While the need to move away from fossil fuels is clear, the path forward must be both workable and sustainable—technically, economically, and environmentally.

Two of San Francisco's leading players in artificial intelligence have challenged the public to come up with questions capable of testing the capabilities of large language models (LLMs) like Google Gemini and OpenAI's o1. Scale AI, which specializes in preparing the vast tracts of data on which the LLMs are trained, teamed up with the Center for AI Safety (CAIS) to launch the initiative, Humanity's Last Exam.

“This is definitely off the charts.”

A new study shows that electric vehicle tax credits under the Inflation Reduction Act reduced pollution and boosted U.S. automakers, but largely benefited buyers who would have purchased EVs without subsidies.

New UBC research analyzing actual pedestrian interactions with vehicles on busy streets concludes that distracted pedestrians face higher safety risks compared with undistracted road users.

The growing use of collaborative robots in the workplace may pose significant psychosocial risks to workers' mental health and their job security, but there are ways for organizations to smooth the transition, according to research from the Monash University Business School.

Batteries power everything from smartphones to electric vehicles, with their performance hinging on the critical interface between the electrode and electrolyte. Penn State and industry researchers have developed a method to observe this interface at a higher resolution, which could potentially reveal new ways to improve battery efficiency and lifespan.

Scientists from the University of Sharjah believe they have created an artificial intelligence system that can automatically identify which Arabic dialect someone is speaking. The work is published in IEEE Xplore.

官员们表示，国际原子能机构的一组科学家周一抵达福岛，执行年度监测和采样任务，以确保处理后的放射性废水安全排放到海中。

预报员预测飓风米尔顿将于周三在坦帕湾地区登陆，带来时速超过 120 英里/小时的风速。

在实验室或临床环境中可靠地跟踪和操纵哺乳动物神经系统使神经科学家能够检验他们的假设，这反过来可能会带来新的重要发现。用于研究大脑的最成熟和最广泛使用的技术利用电极，这些设备可以监测或刺激周围的电活动。

塑料污染无处不在，其中很大一部分是由聚对苯二甲酸乙二醇酯（PET）组成的。这种聚合物用于制造瓶子、容器甚至衣服。现在，研究人员在《环境科学与技术》杂志上报告说，他们发现了一种可以在一个相当不寻常的地方分解 PET 的酶：生活在污水污泥中的微生物。废水处理厂可以使用这种酶来分解微塑料颗粒并回收塑料废物。

在《自然通讯》的一项新研究中，研究人员提出了一种利用湖泊和水库底部现有管道进行储氢的新方法。

Bigfoot is buzzing again after a TikTok went viral this week, with non-believers pointing and laughing ... but one Ph.D. expert on the subject tells TMZ the joke is on them.

Deadly flooding from Hurricane Helene in western North Carolina has disrupted the underground nests of yellow jackets, bees and other insects.

Urban air mobility (UAM) is a mode of transportation that avoids traffic congestion by flying people and cargo above it at low altitudes. It may sound like science fiction or something from the cartoon "The Jetsons," which depicted people going from place to place in flying cars. However, that concept is set to become a reality as electric flying taxis could begin operating in the U.S. as soon as 2025.

The UK government on Friday announced investment of nearly £22 billion ($28.8 billion) in projects to capture and store carbon emissions created by industry and energy production.

The National Technical University of Athens (NTUA), one of the DEDALUS scientific partners, has completed a study on grouping residential electricity consumers, based on their historical electricity consumption, to create more targeted demand-response programs.

On average, Americans spend about 90% of their time indoors, and the air we breathe at work, school or home affects our overall health and well-being.

Researchers have developed a new method to improve both the performance and the stability of solar cells using "perovskite quantum dots." They developed longer-lasting solar cells by addressing the issue of distortions on the surface of quantum dots, which deteriorate the performance of solar cells.
