The birds struggled to raise chicks…

The research, carried out on clonal raider ants at Rockefeller University and published in the journal Nature, shows that two chemical signals in the ant brain, known as neuropeptide F and allatostatin…

Concrete is the backbone of modern civilisation, supporting everything from homes and skyscrapers to bridges, tunnels and dams. Yet even this remarkably strong material has a costly weakness. Tiny cracks inevitably develop over time because…
