Someday, cicadas and dragonflies might save your sight. The key to this power lies in their wings, which are coated with a forest of tiny pointed pillars that impale and kill bacterial cells unlucky enough to land on them.
A team of engineers recently published research on a method for using electric fields to help tiny bio-robots propelled by flagellated bacteria navigate around obstacles in a fluid environment. These microrobots could one day be used for building microscopic devices or even delivering medication at the cellular level.
A research team has observed for the first time how HIV and Ebola viruses attach to cells to spread infection. These findings offer a new way of treating such viruses: instead of destroying the pathogens, introduce a block on how they interact with cells.
Researchers re on a quest to find out as much as they can about unusual states of matter called spin liquids and if these spin liquids could generate advances in the field of physics. The results could lead to the development of quantum computing, which require an exploration of new materials to become a reality.
Scientists have developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries.
Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.
As electronics grow ever more intricate, so must the tools required to fix them. Anticipating this challenge, scientists turned to the body's immune system for inspiration and have now built self-propelled nanomotors that can seek out and repair tiny scratches to electronic systems.
