CBS acquires all of TV Guide Digital

---

TV Guide Digital has fared well between its web portal and mobile apps, but part-owner CBS thinks there's a lot of potential locked away. Enough so, in fact, that CBS is taking over TV Guide Digital by acquiring Lionsgate's remaining 50 percent stake in the venture. The media giant now has full control of both TVGuide.com and the TV Guide Mobile apps, both of which are folding into CBS Interactive's Technology, Games and Lifestyle division. CBS mostly hopes that the deal will make it a font of wisdom for channel surfers -- it sees TV Guide Digital's rapidly growing audience and programming knowledge as complements to TV.com. We don't yet know how the acquisition will affect the TV Guide properties themselves, but we'd expect more than just the status quo.

Mars pebbles prove that rivers altered the planet's surface

Scientists already had an inkling that water helped form the landscape on Mars, but they're now ready to confirm that claim. In a report written for Science, researchers state that the smooth, rounded shape of the Red Planet's pebbles and the way they overlap is identical to the gravel formation found in Earth's rivers. They appear to be too large to be blown by wind, and their varied shades indicate they were transported from various locations -- telltale signs of a former stream. "For decades, we have speculated and hypothesized that the surface of Mars was carved by water, but this is the first time where you can see the remnants of stream flow with what are absolutely tell-tale signs," said Rebecca Williams to the BBC. This isn't the first time we've heard of water on Mars, but the idea of a Martian river does make us wonder if Marvin had a favorite fishing hole.

HTC One Android 4.2.2 update adds UI features, sticks with Sense 5.0

---

If you've already got an HTC One, news of a Sense-free version will have been interesting for the presence of Android 4.2.2, as much as anything else. While we can't tell you when your handset will get updated, we can tell you that it'll bring with it some useful additions. A popular one will be the percentage battery level indicator that you see above. There's also extended quick settings, a long-press-for-menu on the home button, Android Daydream, and some changes to the app drawer (remove icons from the dock etc.). So that's the what, we're just waiting for the when.

LG Optimus F7 for US Cellular leaks through company documents

---

US Cellular isn't just looking to spice up its device roster with the ATIV Odyssey. We've obtained documents that point to LG's upper mid-range Android smartphone, the Optimus F7, also reaching the carrier in the near future. Outside of the unintrusive branding on the back, it's a very straightforward port: the F7 should still carry its 4.7-inch qHD screen, LTE data, a dual-core 1.5GHz processor, an 8MP rear camera and a 1.3MP front camera. The materials we've seen make no mention of launch details, although we're not expecting either a long wait or a high price.
