„My lab is not in the ear-making business. What I’m really curious about is if one day it will be possible to repair, rebuild and augment our own bodies with stuff we make in the kitchen,” says Andrew Pelling who leads a university-based biological research lab. Usually, he likes to rummage through garbage and often digs up discarded hardware he first dismantles and then reassembles into something completely new. Could that also work with a biological system? Creating human ears from apples may be far-fetched, but seems feasible: the lab removed apple cells and DNA and implanted human cells instead. The result was a cellulose scaffold with a structure that could be carved into a human ear!Reading time: about 1 minute

Seventy thousand years ago, our ancestors were insignificant animals roaming African terrain. How fortunate for humankind that the course of evolution was not disrupted at some grave point and just kept rolling – otherwise all of us would perhaps have been locked in the ape-stage for ever. Well, we haven’t, and today humans dominate Earth. But how did it happen?
Historian Yuval Noah Harari suggests that this is the reason for the rise of humanity: “We are the only animals that can cooperate both flexibly and in very large numbers”. Social insects like bees are also able to cooperate in large numbers, but are inflexible in doing so. “They cannot reinvent their social system overnight. They cannot execute the queen and establish a republic of bees, or a communist dictatorship of worker bees.” Why it was us instead of the wolves, elephants, dolphins or chimpanzees is explained in this easy-to-comprehend yet thought-provoking video:Reading time: about 1 minute
Zzzzzzzzzzp! Flash! There you go! A spiteful and cowardly camouflaged radar trap has lashed out at you once again, and another costly and questionably handsome snapshot is on its way into your post box. Fuming traffic offenders are said to have clandestinely returned to the place of crime to take revenge – fortified by a bunch of best-friends’ hercules’s and in order to punish the wicked contraption out of its wits. Ignoring, that there’s sure to be another invincible clone around the next corner. Instead of adding up on the offence front, avoiding speeding and/or respecting red traffic lights may actually do the trick fairly well and entail far less trouble: It allows short tempers to lie dormant just a little while longer and lends bank statements a so much more encouraging appearance. Similar to police records …Reading time: about 2 minutes
There’s screeching violins and scary guns, minute bikinis and most interesting food. Human stem cells, bionic ears, fetuses or King Richard III.’s reconstructed face. With appliances becoming more affordable, 3D printing has not only enriched the options for the science and technology sectors considerably. A wide array of objects can now be designed and printed up to a certain scale with the range stretching from things practical to weird and from commercial products to manufacturing parts. Bioprinting of portions of the human body for medical purposes has revolutionised the field. And a wealth of exciting developments is still in the pipeline. Experts predict that privately owned 3D printers will be a frequent commodity in the not too distant future and 3-dimensional DIY activities a realistic option for virtually everyone.Reading time: about 3 minutes
