Measures to capture carbon in soil may be less effective than hoped, scientists say
Bioengineering soybean plants to improve regulation of photoprotection—a natural process that enables plants to cope with excess absorbed light energy—improved soybean seed yield by up to 33% in field trials.

A collection of papers in this week’s issue probes the vulnerabilities and potential resilience of forests in a warming world. Three studies focus on North America: one examining the response of boreal species to warming and drought, another analysing the timing of stem growth in temperate deciduous forests, and a third revealing migration of white spruce (Picea glauca) into the Arctic tundra. In the tropics, one paper investigates the
Death’s-head moths correct course based on an internal “compass,” a new study finds, revealing insights into how insects traverse such long distances during seasonal migrations.
Marram grass, or beachgrass, grows on and stabilizes coastal sand dunes on Ireland’s Dingle Peninsula. Grasses, whether terrestrial or submarine, tend to be undervalued but have influenced the trajectory of human history through their domestication as food staples, as well as natural ecosystems worldwide. If restored and conserved appropriately, grasslands can benefit climate change mitigation efforts. See the special section beginning on page 590.
