The Missing Link in Star Cluster Evolution

The currently most popular models for the dynamical evolution of star clusters predict that the power-law Cluster Luminosity Functions (CLFs) of young star cluster systems will be transformed rapidly into the universal Gaussian CLFs of old Milky Way-type “globular” cluster systems. Here, we provide the first evidence for a turn-over in the intermediate-age, approximately 1 Gyr-old CLF in the ce...

Evolution: oskar Reveals Missing Link in Co-optive Evolution

The oskar gene is critical for germ plasm formation and reproduction in higher insects. A recent study reports that oskar has more ancient roots than previously thought, indicating it was co-opted for its reproductive role in higher insects.

Evolution of gap junctions: the missing link?

Connexin molecules form gap-junction channels in vertebrates and there are at least 20 of them in humans [1]. Intuitively, one would imagine that cardinal features of the cellular machinery, such as gap-junctions, would be highly conserved. Paradoxically, however, Drosophila and Caenorhabditis elegans do not have connexin genes, but instead use innexins for gap-junctional communication, a prote...

From Evolution to Behavior: Evolutionary Psychology as the Missing Link

“vitality” a missing link in adjustment to childhood cancer

background: a number of randomized trial studies and longitudinal researches emphasize that despite problems in social adjustment and cognitive damages, children with cancer demonstrate good emotional adjustment. methods: most of the research findings in this area are obtained using objective tools such as questionnaires. “vitality of children”, as a drawing tool, was used as a basis to draw a ...
