Recreating Pluripotency?

Recreating ancestral proteins.

Tracing the history of molecular changes using phylogenetic methods can provide powerful insights into how and why molecules work the way they do. It is now possible to recreate inferred ancestral proteins in the laboratory and study the function of these molecules. This provides a unique opportunity to study the paths and the mechanisms of functional change during molecular evolution. What ins...

Retrieving and Recreating Musical Form

This paper discusses musical form from a cognitive and a computational viewpoint. While several time-windows exist in the brain, we here put emphasis on the superchunks of up to more than 30 seconds lengths. We compare a strategy for auditive analysis based on human cognition with a strategy for automatic analysis based on feature extraction. The feature extraction is based on the musical featu...

Recreating the Posterior Chamber Lens

T he history of IOLs began in 1949 with Sir Harold Ridley’s insertion of an artificial lens into the posterior chamber. Although placing an IOL within the space from which the cataract had been removed seemed (and seems still) a natural, almost obvious choice, ophthalmologists abandoned posterior chamber lens implantation within a few years. I reawakened surgeons’ interest in posterior chamber ...

Recreating the Sound of Stonehenge

Stonehenge is the largest and most complex ancient stone circle known to mankind. In its original form, the concentric shape of stone rings would have surrounded an individual both visually and aurally. It is an outdoor space and most archaeological evidence suggests it did not have a roof. However, its large, semi-enclosed structure, with many reflecting surfaces, would have reflected and diff...
