That's because the robot's not galloping, it's bounding. It's a completely different gait.
Believe it or not, people who study animal locomotion do actually do research on animal locomotion.

Funnily enough, those issues are the ones that the article is actually about:
“Most robots are sluggish and heavy, and thus they cannot control force in high-speed situations,” Kim says. “That’s what makes the MIT cheetah so special: You can actually control the force profile for a very short period of time, followed by a hefty impact with the ground, which makes it more stable, agile, and dynamic.”
Kim says what makes the robot so dynamic is a custom-designed, high-torque-density electric motor, designed by Jeffrey Lang, the Vitesse Professor of Electrical Engineering at MIT. These motors are controlled by amplifiers designed by David Otten, a principal research engineer in MIT’s Research Laboratory of Electronics. The combination of such special electric motors and custom-designed, bio-inspired legs allow force control on the ground without relying on delicate force sensors on the feet.
Kim and his colleagues — research scientist Hae-Won Park and graduate student Meng Yee Chuah — will present details of the bounding algorithm this month at the IEEE/RSJ International Conference on Intelligent Robots and Systems in Chicago.
1) One story was the juicy rumour. The other was the confirmation of the juicy rumour. It's not like it's the first time this has happened on Slashdot, or any other tech news site.
2) Two stores is not "so many Minecraft stories"
Yes, there's an auto-download setting on the Mac.
I'm going to go out on a limb here and assume that goarilla was actually just making an atrocious data-mining pun.
Moichandising, moichandising. Minecraft the game isn't worth $2.5 Bn but I suspect that the Minecraft licencing business will probably add up to that much in the long run.
According to Mojang, Microsoft has agreed not to meddle in the development of the game for other platforms, although they point out that they can't do anything about any objections platformholders might have about distributing a Microsoft game.
Yes, "more" is the addition operator, "times" is the multiplication operator. Combining the two is idiomatic but generally read as just meaning multiplication.
I'm still using an iPhone 4, which is now four generations behind. I've had no problem with app performance outside of (of course) 3D games. This thing's aging better than my Nokia 3310 did.
Most apps aren't all that technically demanding.
There's one Android phone shipping with sapphire glass - the Kyocera Brigadier - and it's one of those "ruggedised" models that's permanently moulded into a giant rubber shoe. When the glass was removed from the enormous impact-resistant body, it shattered on the first three-foot drop test:

You won't see a sapphire screen in a non-ruggedised phone any time soon.
It's not a maths issue, it's an issue of idiomatic versus literal English. "N times more" doesn't mean "Add N times the original value", it just means "N times the original value". Similarly "N times less" doesn't mean "Subtract N times the original value", it means "reciprocal N times the original value".
Unfortunately there's no
We've decoded part of that beta invitation... except it doesn't look like it was an invitation. It looks like it was a warning.
You really should've called them out on calling it "BC" rather than "BCE" while you were at it. What's pedantry without thoroughness?
