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'm curios if webmasters are treating IE the opposite relative to the once-dominance of IE6.

Maybe now all the "if IE" conditionals result in a purposely shitty experience, instead of targeting quirks in specific versions.

Missing the point. Of course end users don't care. But if the browsers supported DANE and performed their own DNSSEC lookups if the local resolver can't, then DANE could work.

If the destination site doesn't publish their certs and/or designated CAs in DNS, then the old "trust all built-in CAs" will still apply.
