ScienceDaily (Sep. 27, 2011) Researchers working with adult mice have discovered that learning and memory were profoundly affected when they altered the amounts of a certain protein in specific parts of the mammals' brains.

The protein, called kibra, was linked in previous studies in humans to memory and protection against late-onset Alzheimer's disease. The new work in mice, reported in the Sept. 22 issue of Neuron, shows that kibra is an essential part of a complex of proteins that control the sculpting of brain circuitry, a process that encodes memory.

Mammoth dung has proved to be a source of prehistoric information, helping scientists unravel the mystery of what caused the great mammals to die out.

An examination of a fungus that is found in the ancient dung and preserved in lake sediments has helped build a picture of what happened to the beasts.
