Bird forecasting by radar p.314

Bird migration is influenced by weather, making it hard to predict when birds will pass through a particular place on their route. A model that forecasts bird migrations has been developed using radar data and weather information.

Timing the action of light on matter p.314

Photoemission, the ejection of an electron from a material on the absorption of a photon, is one of the fastest processes in nature. An experiment demonstrates how the dynamics of this process can be captured in real time.

Tissue ‘melting’ sculpts embryo p.315

Collections of cells in the tails of zebrafish embryos have now been found to transition between behaving as solids and fluids. This transition is responsible for the head-to-tail elongation of the embryo.

T cells engineered to home in on brain cancer p.319

Immunotherapies activate T cells to destroy tumours, but the approach has failed in some brain cancers. A strategy to improve migration of T cells across the blood–brain barrier could overcome this limitation.

Absolute timing of the photoelectric effect p.374

The absolute timing of the photoelectric effect has proved difficult to measure, but the delay between photon arrival at a tungsten surface and ejection of photoelectrons has now been determined.

Ancient herders enriched and restructured African grasslands p.387

Isotopic and sedimentary analyses of soils at Pastoral Neolithic archaeological sites in Kenya demonstrate the long-term influence of nutrient enrichment on savannah environments that has accompanied pastoralist settlement over the past three millennia.
