Video demo of Living Molecules app: chemical glyphs on posters

demo_livingmolTo view a very early (pre-pre-alpha) demo of the Living Molecules app, check out this YouTube clip. In a nutshell, this app can be used to photograph molecular glyphs, which work like QR codes, except they unlock explicit chemical content. It can view and import the associated chemical data, export it to other apps, and also be used to create molecular glyphs. These glyphs can be included on posters, documents, websites, etc. Continue reading

Mobile sketcher improvement: charge buttons alongside the periodic table

periodictable_chargesAn addition that I’ve been meaning to implement for awhile: double-tapping on an atom within the structure sketcher, using apps such as the Mobile Molecular DataSheet, MolPrime and others, brings up a periodic table and several sliders that allow atom-specific properties to be edited. Using a slider to edit the charge has always been a little unsatisfactory, so as you can see on the snapshot to the right, there are now 7 additional buttons cradled in the deadzone of the periodic table for quickly setting the charge from -3 through +3.

The modified sketcher feature will appear one app at a time, as they get updated during the natural course of events.

ACS Chemical Information Division (CINF) and the ODDT app

oddt_acscinfOne of the outcomes of the recent American Chemical Society meeting in New Orleans is that my usual haunt – the Division of Chemical Information (CINF) – needs to do a bit more work to publicise itself, and boost the membership count, so it can continue to be an important and relevant fixture in the cheminformatics space. To this end a brainstorming session was held the night before the talks began, and each of us scribbled out as many ideas as we could think of on Post-It notes. One of the ideas that Tony Williams (aka ChemConnector) came up with is to encourage members to tweet out their division-related activities, and use the hashtag #ACSCINF. Then, in the tradition of #RealTimeChem, add a new topic to the Open Drug Discovery Teams app.

First of all, if you have an iPhone, iPod or iPad, and you don’t already have the Open Drug Discovery Teams (ODDT) app installed on it, you need to remedy that by making a quick trip to the iTunes AppStore:

http://itunes.apple.com/app/oddt/id517000016

The app is free. Its purpose is to serve as an aggregator of open content documents for specific science-related topics, which mainly consist of rare & neglected diseases, but also include some precompetitive topics like green chemistry, and some more experimental efforts to involve cheminformaticians in social networking, namely #RealTimeChem and ACS CINF.

The ODDT app contacts a server for its content, which in turn routinely scrapes Twitter and specific RSS feeds. The Twitter-obtained content is an effort to make use of the fact that despite that network being a torrential flood of inanity, there are quite a few sources who post valuable and interesting links, and make the effort to classify their contributions with specific hashtags. ODDT is configured to look for these, and compile them into relevant topics, which means that if you find a relevant document (typically a web page), you can “tweet it into ODDT” by emitting the link and the appropriate hashtag, e.g. #Malaria for articles relating to malaria research. The app provides this information via a browsing interface that was inspired by the very popular Flipboard app.

The second important aspect of its functionality is crowd curation. Documents that are scraped from social networks and added to the system start with an endorsement ranking of 0, which means that they will be kept in the “inbox” for a week, but after that they get flushed. Unless, that is, a user of the ODDT app endorses it. Documents can be voted down as well as up, so as long as its rating stays greater than zero, it will be retained indefinitely. In this way, anything that wasn’t important enough for somebody to endorse gets digested and excreted, leaving behind only the content that people consider valuable.

So if you have any interest in the ACS Division of Chemical Information, you should:

  1. Download the ODDT app, if you have an iThing
  2. Tweet out links to relevant content, and add the #ACSCINF hash tag

Try it out. And let us know what you think!

 

Finding vendors using mobile apps: compliments of PubChem

pubchem_vendorsUsers of the PubChem service may have noticed that the hit records include a list of vendors and links to the compound records for their site (e.g. see here). The Mobile Molecular DataSheet (MMDS) app, among others, can tap into PubChem to search by name or structure. The next version makes use of the vendor information, and provides this to the user as part of the search results. Continue reading
