Cell-sized robots that can change their shape

imagesResearchers at Cornell University built origami machines that can modify their shape in response to different stimuli and carry loads such as embedded electronics. These small robots are extremely small and are produced by graphene actuators that can fold 2D patterns into targeted 3D structures.

This research has no application for the moment, however it opens new paths to robotics for cells and biological systems.

New sensors: monitoring breath for kidney disease

UnknownCurious to see if you have a kidney disease in a very fast way? You can do it by just breathing!

Researchers at the University of Illinois have discovered a sensor based on a nonporous organic semiconductor thin film that can monitor the levels of ammonia in the breath. Since ammonia is a biomarker for chronic kidney disease, this highlights the importance of this research and its future impact in the development of novel health monitoring technologies.

The molecule of this week is theofylline, a methylxanthine that can be naturally found in cocoa beans. This molecule has a very similar chemical structure to other xanthines like caffeine or theobromine. However, it has pharmacological applications as it is used to treat asthma and other respiratory diseases.

Missing winter? Fake snow is what you want!

UnknownWinter has now passed, but some of you might still miss cold and snow…No problem! We have what you are looking for.

You can make some fake snow at home in few seconds. The only things you need are:

  • a superabsorbent polymer (e.g. sodium polyacrylate, which can be obtained by cutting a nappy)
  • water.

Wondering about how to do it? Have a look at this video!


New 3D printing ink can be erased

UnknownErasing 3D printed structures is now possible by using a special ink developed by researchers at Karlsruhe Institute of Technology. The microstructures can be created using a laser and then erased by simple immersion in an organic solvent.

The most interesting part of this research is that erasable structures can be incorporated into non-erasable structures, making this ink very promising for a wide range of applications.
