Molecules 1.4.2 now on the App Store

Molecules icon

A new version of Molecules is now available on the App Store. This adds iOS 4.0 multitasking and Retina display support, and fixes a number of issues that users have identified.

Searches of the Protein Data Bank had been failing if only one molecule met the search criteria, because then the PDB web services would return a web page rather than the normal text results. This is now accounted for, so hopefully all PDB searches should work.

A few amino acid residues had incorrect bonds, and they should all be fixed now. Thanks go to Dr. Steven Muskal of Eidogen-Sertanty for pointing this out. While you're at it, check out their iProtein iPad application, which interacts with Molecules.

The rendering performance of rotating molecules should be improved, particularly on the more powerful devices.

Finally, the visualization mode you select persists until you change it, even across multiple molecules.


It would rock to have caffeine on here. It's sort of geeky de rigeur.

hi Brad Larson,

I read about you in your website. Really great. Can you help me now when you find time?

I have configured xmpp in iphone.I could connect with xmpp server and able to get users list. Now I want to implement chat between those users using xmpp like in monal app. Can you help me?

I am just trying to fix this for last one week. I could not implement this.
Please help me.

Sorry, I have no experience with XMPP, so I can't help you there. You'll probably find better answers on Stack Overflow.

Any chance of updating 'Molecules' to show all the Elements of the Periodic Table? Mainly Carbon, Gold, Silver, Mercuy, Copper, etc.

I'm not sure what you're asking. Molecules already displays molecular structure that contain those elements. What more do you want it to do?
