Students from Australia have unearthed a trove of rare treasures at a site in Israel and may have solved the mystery to King David’s long-lost city of Ziklag.

Coupling electromagnetic waves to mechanical waves has led to a remarkable miniaturization of wireless communication technologies. Now, spin waves could provide us with technologies that are small and reprogrammable.
The scales of the Arapaima, an Amazonian freshwater fish that can weigh up to 440 pounds, possess all the best attributes of a bulletproof vest, but the elements are better integrated into one solid piece combining imperviousness and flexibility, researchers say. The Air Force is funding a study of the fish for potential body armor development.
The fossilised skulls of dinosaur embryos that died within their eggs about 200m years ago, have been digitally reconstructed by scientists, shedding new light on the animals’ development, and how close they were to hatching.
The rare clutch of seven eggs, some of which contain embryos, was discovered in South Africa in 1976, with the developing young found to be a species of dinosaur called Massospondylus carinatus.
The plant-eaters were ancestors of sauropod dinosaurs like diplodocus and, as fully-grown adults, would have walked on two legs, measured about five metres from nose to tail, and had long necks with small heads.
Just a few hours later, Trump tweeted it was his decision — not that of state governors — of when states should re-open.
