Second QSLiMFinder poster now on F1000 Posters

The second QSLiMFinder poster from the recent Cold Spring Harbor Laboratory "Systems Biology: Networks" meeting is now available at F1000 Posters:
  • Edwards RJ & Palopoli N. Computational prediction of short linear motifs mediating host-pathogen protein-protein interactions.
  • (I'm not sure why the last post about the other poster disappeared for a few days but it's back now!

    Second BUDAPEST paper published

    A second paper using BUDAPEST, "Responses of the Emiliania huxleyi proteome to ocean acidification" came out on Friday. An overview can be found in a University of Southampton press release, Marine algae show resilience to carbon dioxide emissions.
    A type of marine algae could become bigger as increasing carbon dioxide emissions are absorbed by the oceans, according to research led by scientists based at the National Oceanography Centre, Southampton (NOCS). The study, published this month in PLoS ONE, investigated how a strain of the coccolithophore Emiliania huxleyi might respond if all fossil fuels are burned by the year 2100 – predicted to drive up atmospheric CO2 levels to over four times the present day.
    You can read the rest of the press release here.

    There are some additional images and a video in a UC Santa Barbara press release, which gives a good summary of the science in the study.
