Meet Nesher Ramla Homo - new early human discovered at Israeli cement site

Scientists said on Thursday they had discovered a new kind of early human after studying pieces of fossilised bone dug up at a site used by a cement plant in central Israel. The fragments of a skull and a lower jaw with teeth were about 130,000 years old and could force a rethink of parts of the human family tree, the researchers from Tel Aviv University and the Hebrew University of Jerusalem said.

Bezos' 2021 Space Odyssey a risk too far for insurers

Launching one of the richest individuals on earth into orbit has proved a leap too far for insurers, who are not ready to price the risk of losing Jeff Bezos or his fellow space travelers.

Fossil find adds to evidence of dinosaurs living in Arctic year-round

Fossils from tiny baby dinosaurs discovered in northernmost Alaska offer strong evidence that the prehistoric creatures lived year-round in the Arctic and were likely warm-blooded, according to a study published on Thursday in the journal Current Biology. The fossils are from at least seven types of dinosaurs just hatched or still in their eggs about 70 million years ago. Researchers have never found evidence of dinosaur nests so far north, said lead author Pat Druckenmiller, director of the University of Alaska Museum of the North.

'Normalizing' UFOs - retired U.S. Navy pilot recalls Tic Tac encounter

Retired U.S. Navy Lieutenant Commander Alex Dietrich has found herself in the glare of media attention ahead of a highly anticipated government report on UFOs, a subject she says she has little interest in, despite actually encountering one on the job.
