The class III phosphatidylinositol-3 kinase complexes I and II (PI3KC3-C1 and PI3KC3-C2) have vital roles in macroautophagy and endosomal maturation, respectively. We elucidated a structural pathway of enzyme activation through cryo–electron microscopy ...

Mitochondrial damage is a hallmark of metabolic diseases, including diabetes, yet the consequences of compromised mitochondria in metabolic tissues are often unclear. In this work, we report that dysfunctional mitochondrial quality control engages a ...

Ice streams are major regulators of sea level change. However, standard viscous flow simulations of their evolution have limited predictive power owing to incomplete understanding of involved processes. On the Greenland ice sheet, borehole fiber-optic ...

True to his campaign promises, on 20 January 2025, US President Donald Trump signed a broad range of Executive Orders, the scope of which ranged from renaming the Gulf of Mexico to “Gulf of America” to reinterpreting the 14th Amendment of the US ...

Under current nationally determined contributions (NDCs) to mitigate greenhouse gas emissions, global warming is projected to reach 2.7°C above preindustrial levels. In this review, we show that at such a level of warming, the Arctic would be transformed ...

Antarctica harbors many distinctive features of life, yet much about the diversity and functioning of Antarctica’s life remains unknown. Evolutionary histories and functional ecology are well understood only for vertebrates, whereas research on ...

Antarctica is a vital component of Earth’s climate system, influencing global sea level, ocean circulation, and planetary albedo. Major knowledge gaps in critical processes—spanning the atmosphere, ocean, ice sheets, underlying beds, ice shelves, and sea ...

The economic benefits of generative artificial intelligence (AI) could reach US$7.9 trillion annually (1). The emergence of groundbreaking generative AI tools has spurred development (2). However, the explosion of generative AI is exacerbating the global climate crisis. The scientific community, industry, and policy-makers must urgently address its effects.

In October 2024, the Australian government announced the expansion of the Heard and McDonald Islands Marine Park Reserve and claimed that 52% of Australian waters are now protected, making the nation the “global leader in marine conservation” (1). That announcement disregards evidence that Australia’s Marine Protected Area (MPA) network has consistently failed to protect important areas of biodiversity (2–6). Australia must substantially improve its MPA network before claiming conservation success.
