Synthetic and biological nanoparticles combined to produce new metamaterials
January 9, 2013

Two different protein cages, cowpea chlorotic mottle virus (blue) and Pyrococcus furiosus ferritin (red), can be used to guide the assembly of binary nanoparticles superlattices through tunable electrostatic interactions with charged gold nanoparticles (yellow). (Credit: Aalto University)   Aalto University scientists have organized synthetic and biological building blocks in a single structure — combining virus particles (and other protein cages) with inorganic nanoparticles to form crystalline layer structures, or superlattices. The research aims to develop hierarchically structured nanomaterials with tunable optical, magnetic, electronic and catalytic properties. Such nanomaterials are important for applications in sensing, optics, electronics and … more…


Wanted: Mars colonists to explore red planet
January 9, 2013

mars-one-colony-2023   The Netherlands-based nonprofit Mars One, which hopes to put the first astronauts on the Red Planet in 2023, released its basic astronaut requirements on Jan. 8, setting the stage for a televised global selection process that will begin later this year, Space.com reports. Anyone who is at least 18 years old can apply to become a Mars colony pioneer. … more…


A paper-thin flexible tablet computer
January 9, 2013

papertab   A flexible paper computer developed at Queen’s University in collaboration with Plastic Logic and Intel Labs could one day revolutionize the way people work with tablets and computers. The PaperTab tablet looks and feels just like a sheet of paper. However, it is fully interactive with a flexible, high-resolution 10.7” plastic display developed by Plastic … more…


Laser and electric fields generate whirlpools to separate microbes
January 9, 2013

wereley-biochip   Researchers have used the newly developed “rapid electrokinetic patterning” (REP) method for the first time to collect microscopic bacteria and fungi, said Steven T. Wereley, a Purdue University professor of mechanical engineering. REP combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine and … more…
