Citizen Science Grid

The Citizen Science Grid is run by Travis Desell, an Assistant Professor in the Computer Science Department at the University of North Dakota. It is hosted by UND's Computational Research Center and Information Technology Systems and Services. The Citizen Science Grid is dedicated to supporting a wide range of research and educational projects using volunteer computing and citizen science, which you can read about and visit below.


Wildlife@Home is citizen science project aimed at analyzing video gathered from various cameras recording wildlife. Currently the project is looking at video of sharp-tailed grouse, Tympanuchus phasianellus, and two federally protected species, interior least terns, Sternula antillarum, and piping plovers, Charadruis melodus to examine their nesting habits and ecology.

Climate Tweets

The Climate Tweets project is focused on personal opinions about climate change or global warming. The goal is to sort tweets and view the different views in various countries, how the discussion has changed over time, and how opinions change with political orientation. Classifying tweets allows us to discover patterns and coorelations in people's opinions about our world. It also helps us understand what people know about climate change. Please note that the tweets are unfiltered and may contain profanity or controversial views, and these are not the views of the Citizen Science Grid, any of our team, or funding agencies. Because of this the project is 18+.


The Subset Sum problem is described as follows: given a set of positive integers S and a target sum t, is there a subset of S whose sum is t? It is one of the well-know, so-called "hard" problems in computing. It's actually a very simple problem computationally, and the computer program to solve it is not extremely complicated. What's hard about it is the running time – all known exact algorithms have running time that is proportional to an exponential function of the number of elements in the set (for worst-case instances of the problem).


The goal of DNA@Home is to discover what regulates the genes in DNA. Ever notice that skin cells are different from a muscle cells, which are different from a bone cells, even though all these cells have every gene in your genome? That's because not all genes are "on" all the time. Depending on the cell type and what the cell is trying to do at any given moment, only a subset of the genes are used, and the remainder are shut off. DNA@home uses statistical algorithms to unlock the key to this differential regulation, using your volunteered computers.

[all] disk issues on server

Looks like we're experiencing some kind of disk issue on the server. I've submitted a support ticket but in the mean time had to shut down the daemons. I hope we have this back up and running shortly.

[all] server issues

Looks like we're experiencing some issues server side where the file_deleter daemon isn't working right. I've cleaned up a little space and am running things to fix workunit/resuilt states in the database so the file deleter does it's job. Hoping to have things fixed by the morning but in the meantime things will be down while the cleanup is happening.

[wildlife] new searches started

Hi Everyone -- got some really interesting results from the last round of searches and we submitted a publication on them last week. Will get a copy out to you soon once we find out if it was published! I've started up a new batch of searches so let me know if you have any issues with these.

[all] data export issues?

Are you still experiencing data export issues? I know our IT staff was having some problems with hardware and the recent migration of where the virtual machine for citizen science grid is being housed. It looks like everything is running on my end but I just wanted to double check with everyone in case some export process got lost in the transition.

[wildlife] more maintenance issues

I apologize for slow loading on the flights this morning. Our IT staff has been doing some things which I think resulted in this. Looks like things are back up and going thankfully. If I hear any more I'll let you know.
