Michigan Technological University Nanosatellites are smartphone-sized spacecraft that can perform simple, yet valuable, space missions. Dozens of these little vehicles are now tirelessly orbiting the earth performing valuable functions for NASA, the Department of Defense and even private companies. Nanosatellites borrow many of their components from terrestrial gadgets: miniaturized cameras, wireless radios and GPS receivers that have been perfected for hand-held devices are also...

[ Watch the Video: Magnetic Droplets on a Superhydrophobic Surface ] Enid Burns for redOrbit.com - Your Universe Online Scientists are experimenting with non-dissapative droplet patterns to study reversible switching between static and dynamic self-assembly. Researchers from Aalto University and Paris Tech studied water droplets containing nanoparticles on a strong water repellent surface to observe the self-assembly process. A video demonstrating the mesmerizing phenomena was posted...

Microscopic particles are being coaxed by Duke University engineers to assemble themselves into larger crystalline structures by the use of varying concentrations of microscopic particles and magnetic fields. These nano-scale crystal structures, which until now have been difficult and time-consuming to produce using current technologies, could be used as basic components for advanced optics, data storage and bioengineering, said the research team. "Not only did we develop the...

Versatile liquid pistons developed at Rensselaer Polytechnic Institute have no solid moving parts, essentially eliminating wear A few unassuming drops of liquid locked in a very precise game of "follow the leader" could one day be found in mobile phone cameras, medical imaging equipment, implantable drug delivery devices, and even implantable eye lenses. Engineering researchers at Rensselaer Polytechnic Institute have developed liquid pistons, in which oscillating droplets of ferrofluid...

(Ivanhoe Newswire) -- Using a healthier hyperthermia, Virginia Tech engineering researchers and a colleague from India unveiled a new method to target and destroy cancerous cells without using chemotherapy. The cancer treatment uses hyperthermia to elevate the temperature of tumor cells, while keeping the surrounding healthy tissue at a lower degree of body heat. The investigators used both in vitro and in vivo experiments to confirm their findings. Ishwar Puri, professor and head of the...

Using hyperthermia, Virginia Tech engineering researchers and a colleague from India unveiled a new method to target and destroy cancerous cells. The research was presented at the 63rd annual meeting of the American Physical Society Nov. 23 in Long Beach, Calif. The cancer treatment uses hyperthermia to elevate the temperature of tumor cells, while keeping the surrounding healthy tissue at a lower degree of body heat. The investigators used both in vitro and in vivo experiments to confirm...

A team led by Yale University scientists has developed a way to rapidly manipulate and sort different cells in the blood using magnetizable liquids. The findings, which will be published the week of December 7 in the online edition of the Proceedings of the National Academy of Sciences, could dramatically improve the speed and sensitivity of tests used to detect cancer biomarkers, blood disorders, viruses and other diseases. Ferrofluids are comprised of magnetic nanoparticles suspended...

What do Saturn and flowers have in common?As shapes, both possess certain symmetries that are easily recognizable in the natural world. Now, at an extremely small level, researchers from Duke University and the University of Massachusetts have created a unique set of conditions in which tiny particles within a solution will consistently assemble themselves into these and other complex shapes.By manipulating the magnetization of a liquid solution, the researchers have for the first time coaxed...

Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. These changes in viscosity occur within a fraction of a millisecond "“ far faster than conventional mechanical means "“ and can be used to effectively control vibrations in applications dealing with actuation, damping, robotics and mechatronics. In this study published in AZojomo*, researchers Jorge A. Cort©s R., Leopoldo S....


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
