Flower from another hour Russian scientists have regenerated a flowering plant from tissue that was frozen in Siberian permafrost for over 30,000 years. The resurrection of the plant, scientifically named Sylene stenophylla, could pave the way for similar experiments on other extinct organisms, researchers hope. The findings are published in the Feb. 21 issue of the journal Proceedings of the National Academy of Sciences . (Image courtesy of the Russian Academy of Sciences, Institute of Cell Biophysics)

Researchers are beginning to turn a corner in accurately simulating the large role of clouds and fine particles in setting Earth's temperature Is colony collapse disorder just the visible part of a "global pollinator crisis"? The answer is surprisingly murky. To help answer the question, scientists have created an inexpensive, nationwide wild bee monitoring program News | Mind & Brain

Print this Anomaly at U.S. Particle Accelerator May Be Physics Breakthrough April 8 - Fermi National Accelerator Laboratory physicists announced the discovery of a “bump” in data that, if verified, could signify the existence of a new particle or force of nature -- or even be evidence of an unexpected form of the hypothetical Higgs boson particle. The finding stems from one of two experiments conducted at Fermi’s Tevatron, which collides beams of protons and antiprotons moving at energies of nearly 1 trillion electron volts.

Thursday, 5 April 2012 Changes in the Earth's axis of rotation and its orbit around the Sun may have triggered a series of sudden, extreme global warming events 55 million years ago, by beginning a thaw of permafrost. Fossils of a previously unknown species of giant feathered tyrannosaur have been unearthed in China, a discovery that shows for the first time it was not just small dinosaurs that had bird-like feathers.
