The alien hand syndrome: What makes the alien hand alien?

The alien hand syndrome is a deeply puzzling phenomenon in which brain-damaged patients experience their limb performing seemingly purposeful acts without their intention. Furthermore, the limb may interfere with the actions of their normal limb. We report a case of alien hand syndrome following a left medial frontal and corpus callosum ischemic lesion. From our clinical observations and the pa...

Alien Maps of an Ocean-bearing World

When Earth-mass extrasolar planets first become detectable, one challenge will be to determine which of these worlds harbor liquid water, a widely used criterion for habitability. Some of the first observations of these planets will consist of disc-averaged, time-resolved broadband photometry. To simulate such data, the Deep Impact spacecraft obtained light curves of Earth at seven wavebands sp...

Alien invaders

Thousands of species have invaded new territories in recent decades, often aided by global trade and man-made habitat change. While many remain harmless, some may cause serious damage. Therefore, we need improvements in surveillance and in our understanding of which factors make a successful invasion possible.

Alien Intelligence

Abduce Deduce Validate Purpose Criteria Perceptions Concepts The Intelligence Process 3 We show here that validation can fail and the process will cycle until a solution (of some sort) is found. The decision to finish depends upon a validation criteria. Such a criteria will be different depending on the kind of problem to be solved. Mathematical induction will thus explore formally every natura...
