Untethered Miniature Origami Robot That Self-Folds, Walks, Swims, and Degrades 3

A miniature robotic device that can fold-up on the spot, accomplish tasks, and disappear by degradation into the environment promises a range of medical applications but has so far been a challenge in engineering. This work presents a sheet that can self-fold into a functional 3D robot,actuate immediately for untethered walking and swimming, and subsequently dissolve in liquid. Further, the robot is capable of conducting basic tasks and behaviors, including swimming, delivering/carrying blocks, climbing a slope, and digging. The developed models include an acetone-degradable version, which allows the entire robot's body to vanish in a liquid. Thus this experimentally demonstrate the complete life cycle of this robot: self-folding,actuation, and degrading.

I'll take your lack of specific examples of bigotry, even against the dictionary definition: "intolerance toward those who hold different opinions from oneself" as an admission that you're blowing smoke. Disagreeing with "their ideas" is not "intolerance toward those".
You seem to play d_r's game of raping the language in support of Holy Progress. Or am I overlooking something?

Jeb who? If the little brother somehow threads it, it won't be due to the religious right. See 2012 election, where said constituency kinda left Romney hanging in the breeze.
If you want to posit an anti-Mormon bias, that's OK. But what substantial religious qualifications does Jeb have?
tl;dr: I think this argument is weak tea, myself.

Google Photos Launches With Unlimited Storage, Completely Separate From Google+ 43

Posted by timothy
from the delete-is-the-hardest-key-to-press dept.
An anonymous reader writes with a report that Google yesterday announced at its I/O conference a photo-storage site known as Google Photos. Says the article: The new service is completely separate from Google+, something Google users have been requesting for eons. Google is declaring that Google Photos lets you backup and store "unlimited, high-quality photos and videos, for free." It's a bit creepy to see all the photos that Google still has on tap, including many that I've since deleted on my phone.

The Case For a Muon Collider Succeeding the LHC Just Got Stronger 25

Posted by timothy
from the other-people's-money dept.
StartsWithABang writes: If you strike the upper atmosphere with a cosmic ray, you produce a whole host of particles, including muons. Despite having a mean lifetime of just 2.2 microseconds, and the speed of light being 300,000 km/s, those muons can reach the ground! That's a distance of 100 kilometers traveled, despite a non-relativistic estimate of just 660 meters. If we apply that same principle to particle accelerators, we discover an amazing possibility: the ability to create a collider with the cleanliness and precision of electron-positron colliders but the high energies of proton colliders. All we need to do is build a muon collider. A pipe dream and the stuff of science fiction just 20 years ago, recent advances have this on the brink of becoming reality, with a legitimate possibility that a muon-antimuon collider will be the LHC's successor.

Third Stage Design Problem Cause of Most Recent Proton Failure 45

Posted by timothy
from the no-richard-feynman dept.
schwit1 writes: The Russian investigation into the latest Proton rocket failure has concluded that the failure was caused by a design failure in the rocket's third stage. The steering third stage engine failed due to excessive vibration as a result of an imbalance in a rotor of a pump unit. While it is always possible for new design issues to be discovered, I wonder why this problem hadn't been noticed in the decades prior to 2010, when the Proton began to have repeated failures.

Submitted by schwit1
schwit1 writes: Rather than simply turn off the spacecraft when its funding runs out at the end of 2015, Rosetta's science team have proposed that the mission get a nine month extension, during which they will slowly spiral into the comet and gently land.

Their proposal is similar to what American scientists did with their NEAR spacecraft, which hadn't been designed to land on an asteroid but was successfully eased onto the surface of Eros, where it operated for a very short time.

Can you provide a sensible definition of 'bigotry', and an example of where you think Carson and Cruz have failed to live up to your proposed standard?
The 'b' word seems to be the all-purpose kiss-off, these days. You risk evacuating it of meaning, like Tarantino did the Bigger Digger Trigger in "Django Unchained", I'm led to understand.

You have junk mail.
