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.

‘Smart cities’ seek to maximize connectivity to improve urban mobility.

Global shark and ray populations have declined sharply, driven by expanding fisheries and inequitable gaps in catch, trade and distribution data. This Review assesses global status, highlights drivers of decline, and outlines the regulatory, market-based and conservation actions needed to reduce mortality and reverse shark and ray biodiversity loss.

Researchers lay bare the human toll of lay-offs, funding cuts and attacks on science one year after the president’s return to the White House.
