Walking octopuses discovered

Two little species of Indian Ocean octopus can tuck up six of their arms while running on the other two, US researchers have reported. They can use their other six arms to disguise themselves from predators, either as rolling coconuts or clumps of floating algae, the team at the University of California Berkeley and Universitas Sam Ratulangi in North Sulawesi, Indonesia found. The discovery, published in the journal Science, discredits theories that walking requires hard bones and skeletal muscle, as octopuses have neither.

Dinosaur Fossil Could Contain Cells

A 70-million-year-old Tyrannosaurus Rex fossil dug out of a hunk of sandstone has yielded soft tissue, including blood vessels and perhaps even whole cells, US researchers reported. Paleontologists forced to break the creature's massive thighbone to get it on a helicopter found not a solid piece of fossilized bone, but instead something looking a bit less like a rock. When they got it into a lab and chemically removed the hard minerals, they found what looked like blood vessels, bone cells and perhaps even blood cells. ViaTECHNOLOGY | NEWS | tvnz.co.nz
