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.
In a breakthrough for energy-efficient computing, engineers have shown for the first time that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics.
Liposomes are currently used as drug delivery vehicles but recognized by the immune system. Scientists have now shown that special artificial liposomes do not elicit any reaction in human and porcine sera as well as pigs.
Researchers have developed a new materials recipe for a battery-like hydrogen fuel cell - which surrounds hydrogen-absorbing magnesium nanocrystals with atomically thin graphene sheets - to push its performance forward in key areas.
Researchers have designed a new type of foldable material that is versatile, tunable and self actuated. It can change size, volume and shape; it can fold flat to withstand the weight of an elephant without breaking, and pop right back up to prepare for the next task.
