A research team at the National Institute of Standards and Technology (NIST) has come up with a potential solution to a two-pronged problem in medical research: How to capture cells on a particular spot on a surface using electric fields and keep them alive long enough to run experiments on them. Their method, which involves innovations upon conventional cell-capture techniques, has already proved effective in creating arrays of human liver cells and mouse pluripotent cells"”which,...

Depending on whom you ask, nanoparticles are, potentially, either one of the most promising or the most perilous creations of science. These tiny objects can deliver drugs efficiently and enhance the properties of many materials, but what if they also are hazardous to your health in some way? Now, scientists at the National Institute of Standards and Technology (NIST) have found* a way to manipulate nanoparticles so that questions like this can be answered. The team has developed a method of...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
