Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii r of approximately 10-100 parsecs and stellar masses M≈ 10-10solar masses, UCDs are among the densest known stellar systems. Although similar in appearance to massive globular clusters, the detection of extended stellar envelopes, complex star formation histories, elevated mass-to-light ratio and supermassive black holes suggest that some UCDs are remnant nuclear star clusters of tidally stripped dwarf galaxies, or even ancient compact galaxies.

There is evidence that routine health checks in primary care may improve outcomes. We conducted a randomised controlled trial of practice nurse led health checks.

There are no cures or disease-modifying therapies, and this may be due to our inability to detect the disease before it has progressed to produce evident memory loss and functional decline.

In this article, the authors use genome-wide association study and linkage data derived from Parkinson's disease studies to illustrate how algorithms that use gene and protein interaction databases reveal subnetworks in biological systems that suggest mechanisms for disease progression. Network modeling may help develop testable hypotheses for neurodegenerative diseases and open up new avenues for therapeutic development.
