Tiny sensors that stick to crop leaves and transmit health data. Robot buggies that trundle up and down orchard rows. Hyperspectral scanners to assess tree health. Smartphone-operated virtual cattle fences. Gene manipulation to transform crops so they’re a different colour or last longer, or bear fruit in a more convenient way.

How about saving the Great Barrier Reef with a one-molecule-thick layer of natural calcium carbonate that floats on the sea surface and reduces the damaging heat of the sun on corals? Maybe the answer is cloud-brightening — spraying microscopic droplets of seawater into the atmosphere to form clouds and provide more shade for the heat-battered …read more
Somebody familiar with the tiny red-dirt town of Marree is good at keeping a giant secret. Marree, population 150, sits at the junction of the Oodnadatta and Birdsville tracks in the remote upper north of South Australia, east of one of Australia’s great mysteries: the “Marree Man”, a 4.2km-long reproduction of a giant Aboriginal figure …read more
Stephen Hawking has left a big black hole in the hearts of millions: people who admired his enormous intellect, his wicked sense of humour, and his extraordinary courage in battling a debilitating medical condition that left him slumped in a wheelchair and communicating via a machine.
