Spectrum is the new oil. Or, so it would appear given all the backbiting that's overtaken the wireless industry as of late. One company, however, is perched advantageously to benefit from these squabbles and that's Cox. In separate filings to the Commission dated today, the cabler's begun the official process of seeking approval to transfer portions of its 700MHz holdings in the A and B blocks -- acquired during an FCC auction back in 2008 -- to U.S. Cellular and AT&T, respectively. Barring any (Big Red) opposition, this exchange would put eight licenses in AT&T's fold and four in U.S. Cellular's that would enhance existing voice and date service, while also aiding in LTE buildout across southern CMAs. All three parties still have a ways to go before these deals pass regulatory approval, but if the recent state of the wireless union's any indication, one of the three primary carrier colors is bound to rear its nay-saying head.

Those who've liked Firefox for Android but have been clamoring for a native version can rest easy, as there's now a truly optimized version waiting for you in Google Play. Mozilla's new Firefox 14.0 beta now looks like, and importantly runs like, a full member of the Android family. Making the leap also affords it Flash support, a new starting page with top sites, secure Google searches and a slew of load time and responsiveness upgrades over the creakier, XUL-based version. Beta status should still trigger a moment of pause if you're not ready to accept a few bugs, but if you've got Android 2.2 or later, you're welcome to give Firefox a shot.

When stretched out, the genome of a single human cell can reach six feet. To package it all into a tiny nucleus, the DNA strand is tightly wrapped around a core of histone proteins in repeating units -- each unit known as a nucleosome. To allow access for the gene expression machinery the nucleosomes must open up and regroup when the process is complete.
