Scientists, wringing their hands over the identity of the famed "hobbit" fossil, have found a new clue in the wrist. Since the discovery of the bones in Indonesia in 2003, researchers have wrangled over whether the find was an ancient human ancestor or simply a modern human suffering from a genetic disorder.

PHILIPPINES - A Philippine court has temporarily halted an application to bring genetically modified (GM) rice to the country, pending a study of possible health and environmental effects.

A temporary restraining order was issued yesterday (18 September) after Greenpeace, together with other nongovernmental organisations, challenged the Philippine government's right to approve Bayer Crop Science's LL62, a herbicide-tolerant type of hybrid rice.

WASHINGTON (Reuters) - The vicious little dinosaur Velociraptor was a feathered fiend, according to scientists who found evidence of quills on this well-known meat-eater's forearm.

In research published on Thursday, paleontologists said a forearm bone of Velociraptor found in Mongolia's desolate Gobi desert retained structures, or quill knobs, where a series of feathers were anchored to the bone with ligaments.

LONDON (Reuters) - An ancient British bog that pumped out high amounts of greenhouse gases during a period of global warming 55 million years ago may offer clues about future climate change, researchers said on Wednesday.

An analysis of sediments from the bog suggests that global warming caused methane emissions to rise in the wetlands, which in turn sent temperatures there even higher, the researchers said.

In a cavern under a remote Arctic mountain, Norway will soon begin squirreling away the world's crop seeds in case of disaster.

Dynamited out of a mountainside on Spitsbergen island around 1,000 km (600 miles) from the North Pole, the store has been called a doomsday vault or a Noah's Ark of the plant kingdom.

New twist on time-tested technology: Heat Pumps.
September 20, 2007 07:28 AM - , Private Landowner Network

To be realistic, it’s hard to imagine every home, apartment building or condominium complex in the world converting to solar energy for heat, hot water and electricity (or any other onsite renewable energy for that matter). Further, given the low proportion of renewables currently on the world’s power grids, it’s hard to see every building on the planet powered by renewables for quite some time.
