The next robot crawling through your gut could be a gummi bear
The future of robotics is decidedly squishy. We've already seen gel-based 'bots that can catch fish, mimic octopi and even ones that can keep your heart pumping. And, if the researchers from Switzerland's EPFL are successful, they could soon be crawling around in our intestines as well.
Daily Mac App: Gelatin
Some tasks need a really simple, straightforward, no-nonsense app to get the job done. Combining PDF files is one of those tasks, and Gelatin is the app to do it. Preview can do a similar thing, but it's certainly not as straightforward as Gelatin. The app offers a window to drag-and-drop the files you want combined together onto. Select them in finder in the order you want them melded and drop them onto Gelatin. The app will take care of the rest spitting out a PDF with all the files you've dropped onto it joined end-to-end. You can take the file and edit it up with Preview, email it off or save it. Gelatin is free for a limited time and is worth a download for the shear ease of use. If you ever need to combine PDF files, making Gelatin part of your workflow could save you time and effort.
Human-derived gelatin spares the livestock, confuses vegans
Vegans are going to be super-conflicted by this one. Researchers at Beijing University's College of Life Science and Technology are pioneering a four-legged creature friendly method for cranking out the 300,000 tons of gelatin produced each year. Their solution: people. Well, not in the Soylent Green sense. No, the process in question here takes "human gelatin genes [and inserts them] into a strain of yeast [producing] gelatin with controllable features." Sound appetizing? It might, if you want to avoid chowing down on "Mad Cow" tainted gummy worms at the cinema. Alright, so maybe these Chinese scientists are signaling the sensationalist red alert a bit prematurely -- it's just too bad Charlton Heston isn't around to witness this bit of life science imitating his art.
