| How children's brains memorize math facts Posted: 17 Aug 2014 07:01 PM PDT As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why. Now, new brain-imaging research gives the first evidence drawn from a longitudinal study to explain how the brain reorganizes itself as children learn math facts. |
| Evolutionary misfit: Misunderstood worm-like fossil finds its place in the Tree of Life Posted: 17 Aug 2014 07:00 PM PDT One of the most bizarre-looking fossils ever found -- a worm-like creature with legs, spikes and a head difficult to distinguish from its tail -- has found its place in the evolutionary tree of life, definitively linking it with a group of modern animals for the first time. |
| Fascinating rhythm: Light pulses illuminate a rare black hole Posted: 17 Aug 2014 07:00 PM PDT Astronomers have accurately measured -- and thus confirmed the existence of -- a rare intermediate-mass black hole about 400 times the mass of our sun in a galaxy 12 million light years from the Milky Way. The finding uses a technique never applied in this way before, and opens the door to new studies of these mysterious objects. |
| Posted: 17 Aug 2014 06:58 PM PDT In an environment where others struggle to survive, Tibetans thrive in the thin air of the Tibetan Plateau, with an average elevation of 14,800 feet. A new study is the first to find a genetic cause for the adaptation and demonstrate how it contributes to the Tibetans' ability to live in low oxygen conditions. |
