Unusually preserved fossils shed new light on how macroscopic, complex life evolved and lived 550 million years ago
Scientists interested in ancient life have a wealth of fossils and impressions frozen in rocks that they can study from as far back as 540 million years ago – when animals with shells and bones began to become plentiful. But evidence of complex life older than 540 million years is scant and difficult to study.
Now, a research team from Virginia Tech in the United States and Nanjing Institute of Geology and Paleontology in China has discovered uniquely well-preserved fossils form from 550 million year old rocks of the Ediacaran Period. Shuhai Xiao, geoscientist from Virginia Tech, with Bing Shen, a Virginia Tech graduate student, and Chuanming Zhou, Guwei Xie, and Xunlai Yuan, all of the Nanjing Instititue of Geology and Paleontology, report in the Proceedings of the National Academy of Sciences (PNAS) the discovery of these unusually preserved fossils which reveal unprecedented information about the body construction of macroscopic organisms more than half billion years ago. The article has been published in the PNAS Online Early Edition the week of July 11 - 15, 2005.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
