Nanosponges “Soak Up” Toxins and Antibiotic-Resistant Bacteria

Engineers at the University of California have developed a “nanosponge” that can safely remove a variety of dangerous toxins from the bloodstream. Unlike other antitoxin platforms, this technology is not limited to a single type of threat. These nanoscale sponges can "soak up" MRSA, E. coli and other antibiotic-resistant bacteria, as well as venom from snakes and bees. Studies performed on mice show that 89% of the test subjects inoculated with the sponges survived a lethal dose of MRSA. Those injected after exposure to a lethal dose still had a high survival rate of 44% .

The nanosponges are made of a biocompatible polymer core. In order to evade the immune system and remain in circulation in the bloodstream, the sponges are wrapped in red blood cell membranes. A single red blood cell membrane can generate thousands of nanosponges. The nanosponges work by outnumbering red blood cells, serving as "decoys" for the bacteria and toxins.

Should men be able to give birth to children?


Koert van Mensvoort: Is the artificial womb frankenstein-like symbol of (male) engineers trying to steal the magical womb from women? Or… is it a feminist project and needed to reach through equality between the sexes? I personally lean towards the latter. To me it feels like progress if a girl can tell a guy to carry the womb for a change.
