Global h-index ranking

For whatever Hirsch`s metric of the h-index may be worth it or not, here are a few extracts from the recent analysis of Google Webometrics. The data is based on Google Scholar Citations and GSC public profiles and, thus, for sure not complete.

Worldwide ranking of highly cited researchers (h>100) according to their Google Scholar Citations public profiles:

Rank 1: Sigmund Freud (University of Vienna), h: 251 (367305 citations)
Rank 8: Richard Flavell (Yale University), h: 197 (145338 citations)
Rank 19: Matthias Mann (Max Planck Society), h: 177 (143407 citations)
Rank 21: Guido Kroemer (INSERM), h:  173 (124638 citations)
Rank 25: Joseph Stiglitz (Columbia University), h: 169 (175827 citations)
Rank 28: Eugene Koonin (National Institutes of Health), h: 164 (112733 citations)
Rank 39: Leroy Hood (Institute for Systems Biology, h: 157 (117200 citations)
Rank 40: Karl Marx (University of Bonn, Berlin and Jena), h: 156 (208910 citations)
Rank 137: Vishva Dixit (Genentech), h: 130 (76957 citations)
Rank 187: Theodor Adorno (Goethe Universität Frankfurt), h: 123 (105100 citations)

Learning from twins

A large meta-analysis of >2700 genetic studies with mono- and dizygotic twins estimated the heritability of complex trains. For instance, the genetic influence of eyes seems to be relatively high (73%), whereas the genetic determinants for the voice seem to have a much lower impact (15%).

How to trade time

How to trade time? Ask Ruth Belville, also known as the Greenwich Time Lady. Each morning from 1892-1939 she would first visit the Royal Greenwich Observatory to set her chronograph called “Arnold” . Then she would wander through the streets of London selling the commodity of Greenwich Time to businesses. In a time where each village had its own time, her service ensured a standard of time to a larger area, which became key for banks, national train services, etc. By 1939 this was taken over by new telecommunication technologies such as the telegraph and, finally, telephony.

Later on Ruth would take over the job of her mum Elizabeth Belville. Once Belville has the accuracy of her watch  ’Arnold’ confirmed in this way, she went on ‘take the time’ round businesses in the West End and City of London.  (Photo by Fox Photos/Hulton Archive/Getty Images)

Why measles vaccination protects also from other microbes

Measles virus infection, just like LCMV or influenza virus, is known to cause severe immunosuppressive effects that predispose to secondary super infections. A recent population-level study by Mina MJ et al. in the journal Science found that non-measles infectious disease mortality is coupled to measles incidence, i.e. indicating that measles vaccination also prevents measles-associated immunosuppression and secondary infections by other pathogens.

Long-term measles-induced immunomodulation increases overall childhood infectious disease mortality. MJ Mina et al. Science 8 May 2015

Interestingly, in 1908 the Austrian paediatrician Clemens von Pirquet was the first scientist who recognised that (measles) virus infection results in reduced cellular immunity against tuberculosis. This important clinical finding triggered numerous studies on the molecular mechanisms of virus-induced immunosuppression.

City fingerprinting

French researchers have grouped 131 cities according to their geometric street patterns using Open Street Map. Next obvious step could be to do functional  ”network biology” of traffic, utility networks, public facilities, outlets, schools, meeting points, etc.

Obituary on Carl Djerassi, 91

Dr. Carl Djerassi died in San Francisco on 30 January. Dr. Djerassi lived many impressive lives, including the life of an outstanding chemist, of a prolific and world-changing inventor and of a science communicator. In addition, he turned to become a novelist and play wright, coining the new genre of “science-in-fiction”. Of note, he was one of the many Jewish intellectuals who were expulsed from Austria by the Nazis and nevertheless (or rather because of that?) went on to pursue a stellar career that brought him to the US, Mexico and beyond. His intellect and wit will be missed.

Obituary in the New York Times (by Robert D. McFadden, Jan 31 2015)
