Scientists have found evidence that material contained in young oceanic lava flows originated at the Earth’s surface in the Archean (>2.45 billions years ago). The new finding helps constrain the timing of the initiation of plate tectonics, the origin of some of the chemical heterogeneity in the Earth’s mantle, and may shed light on how the chaotically convecting mantle could preserve such material for so long.

Taking a significant step toward improving the power delivery of systems ranging from urban electrical grids to regenerative braking in hybrid vehicles, researchers have synthesized a material that shows high capability for both the rapid storage and r… Continue reading →
Women tend to carry excess fat in their hips and thighs, while men tend to carry it on their stomachs. But after menopause, things start to change: many women’s fat storage patterns start to resemble those of men. This indicates that there’s a link bet… Continue reading →
Researchers have developed a cloud-computing platform for robots. The platform allows robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers – the giant server f… Continue reading →
Researchers have shown, for the first time, that a method of storing nuclear waste normally used only for high level waste, could provide a safer, more efficient, and potentially cheaper, solution for the storage and ultimate disposal of intermediate l… Continue reading →
Rechargeable batteries are no doubt an investment. The upfront cost makes those $5 single-use batteries seem much more appealing.
But despite the price, The National Electrical Manufacturers Association has estimated that U.S. demand for rechargeables is growing twice as fast as demand for non-rechargeables.
Just how high is that demand? More than 350 million rechargeable batteries are [...] Continue reading →
