Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. They covered the ball-shaped microroller with a magnetic nanofilm on one side and with anti-cancer drugs on the other. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
The JEDI Billion Molecules against Covid-19 Grand Challenge was launched at the beginning May. The call for submissions is open until June 6.
Using supercomputing and AI, participating teams will screen enormous molecular libraries against the virus's protein targets. Results will be cross-correlated to determine a “high potential” list of unprecedented quality, allowing a fast track to clinical testing.
Congratulations to the Rationality Enhancement Group on two abstracts being accepted for the first round of submissions for the ClearerThinking.org micro grants!
Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart aim to understand the underlying process of self-assembly. Their findings not only provide valuable insights into fundamental physics, but could enable the design of functional materials or self-assembled miniature robots.
An interdisciplinary team of scientists from Stuttgart, Heidelberg, and London developed miniature magnetic nanopropellers that can deliver genetic material to cells. They used a magnetic material that outperforms the strongest known micromagnets, yet is chemically stable, non-toxic and biologically compatible. Such new nanopropellers hold great potential for biomedical applications and minimally invasive surgeries of the future.

Researchers at the Max Planck Institute for Intelligent Systems have discovered a new mechanism of self-organization of active matter. When photochemically active nanoparticles are enclosed at high density within a drop and are exposed to UV light, a self-organized flow pattern emerges by spontaneous symmetry breaking. Furthermore, each drop communicates with neighbouring drops by exchanging chemicals, and coordination of their internal flows occurs – even when far apart.
