Stone tools illustrate behavioural complexities in Middle Pleistocene hominin populations. Here, the authors present small dimensional flakes and hafted tools from Xigou, central China, dated to ~160–72 thousand years ago that demonstrate early, complex technological advancements.

Reconstructing chemical variations of magma during rifting is challenging due to the heterogeneous mantle sources of the melt and different evolution pathways that magma potentially takes. Therefore, ...

Humanity’s Last Exam, a multi-modal benchmark at the frontier of human knowledge, is designed to be an expert-level closed-ended academic benchmark with broad subject coverage.

‘Exercise snacks’ and other forms of everyday movement can greatly reduce the risk of heart disease and death.

The authors mapped spontaneous and choice activity across mouse prefrontal cortex. The activity maps aligned with intrinsic connectivity rather than anatomical subregions, suggesting that connectivity, not cytoarchitecture, organizes prefrontal function.

For almost two decades, scientists have debated whether sponges or comb jellies are the first animal lineage. Now some are calling for a more harmonious approach.

Women with ADHD are, on average, diagnosed five years later than their male counterparts. Recently diagnosed with ADHD at 34, Emily Bates explores why it took her over three decades to put a name to her disobedient brain. Drawing on her own experience alongside conversations with ADHD researchers and other women diagnosed later in life, this film explores how ADHD has historically been misunderstood in women, and why diagnosis often comes years later than it should. As awareness grows, fuelled in part by social media, can we find comfort in community whilst avoiding the risks of misinformation and what do rising diagnosis rates really mean?

In a randomized controlled trial that included 97 participants, 69% patients with Crohn’s disease (CD) allocated to a fasting-mimicking diet (FMD) achieved clinical response, and over 60% reached remission, outperforming the control group. The FMD also reduced markers of intestinal inflammation, suggesting this dietary intervention could serve as adjunctive treatment for CD.
