-Bullhorn, a Boston-based company that develops front office software for staffing and recruiting businesses, nailed $26 million in funding this week. Bullhorn's using the dough to expand its operations within the region and to develop new products. The company seems to be one of the few profitable firms that VCs are investing in these days—its revenues rose 67% in 2007, with $13.6 million in profit.

-You may think that if you're going to invest in airborne objects that spaceships, green rockets, or, hell, flying saucers, would make the most sense. Well, you'd be wrong. After scoring $8 million in VC funding, Airship Ventures is bringing zeppelins back to San Francisco for "flightseeing" tours. Word is that they'll be flying with safer fuel than the Hindenburg.

-GenVault, a "leader in room temperature biosample management" (we don't know what that means either), secured $13 million in second round funding. They plan to use the money for equally nebulous projects that include "room temperature biosample preservation, storage, and distribution for biobanking, translational medicine, and applied testing applications." Would whoever wrote the press release over at GenVault please see this post?

-Here's a shocker: Innovation Fuels, a biodiesel company, secured $15.5 million in VC funding this week and a $160 million credit line. Along with biodiesel production, the company also plans to work with algae, which is becoming increasingly popular as a potential source of energy, and Jatropha—a South American bush. No word yet on what they plan to do with that.

-NileGuide received $8 million in second round funding from a group of investors including Lehman (Who knew they had money to give away right now?). Nile is an online travel guide customized for your trip. Plug in where you're going and Nile amalgamates info on those locales from numerous online sources, as well providing articles from its own reviewers.
