A short overview is presented of several topics concerning the evolution of the Milky Way (MW) in a cosmological context. In particular, the metallicity distribution of the MW halo is derived analytically and the halo metallicity and abundance patterns are compared to those of Local Group galaxies. The inside-out formation of the MW disk is supported by the observed evolution of the abundance g...

The quest for historically impactful science and technology provides invaluable insight into the innovation dynamics of human society, yet many studies are limited to qualitative and small-scale approaches. Here, we investigate scientific evolution through systematic analysis of a massive corpus of digitized English texts between 1800 and 2008. Our analysis reveals great predictability for long...

In a recent editorial I discussed the future of scientific publication. 1 I mentioned Joshua Lederberg’s EUGRAM— the process of sending messages and “publishing” papers via computer terminals. z While Lederberg’s preview of the future may cause some readers “future shock, ” I wondered how much different publication will be in 2001 than it was 300 years ago.

Although the diagnosis of acute diverticulitis is somewhat standardized, the scientific evidence and basis for treatment has been questioned. For years, medical and surgical management of acute diverticulitis has been based on the theory that more than 2 significant attacks of diverticulitis would lead to the recommendations of surgical resection. This should be questioned and further investiga...
