New biotechnology for high efficiency purification of live human cells
Cell therapies require a purification step that isolates the desired cell types from contaminating cells. Normally cell surface receptors are used as markers to distinguish cell types, but undesired cell types also show these ...
Researchers use CRISPR to create 'kill switch' for GMOs
Scientists develop atomic-scale hardware to implement natural computing
Molecular switch that promotes heart cell maturation discovered
A molecular switch that seems to be essential for embryonic heart cells to grow into more mature, adult-like heart cells has been discovered.
New way to purify arrays of single-walled carbon nanotubes a step toward post-silicon circuits
The exceptional properties of tiny molecular cylinders known as carbon nanotubes have tantalized researchers for years because of the possibility they could serve as a successors to silicon in laying the ...
Physicists report technology with potential for sub-micron optical switches
A team that includes Rutgers University and National Institute of Standards and Technology scientists believes that a technology it is reporting this week in Nature Photonics could result in optical switch ...
Indiegogo project 'Switchmate' lets you run light switch from your phone without rewiring
Largest-scale silicon photonic switch: Low loss optical design enables up to 2,500 switch elements on 1 x 1 cm chip
Today's explosion of video and Internet data is driving unprecedented traffic demand within datacenters. With data transfer rates exceeding 100 gigabits-per-second (Gb/s), communication between servers requires optical switches ...
Popular origami pattern makes the mechanical switch
An origami paper-folding pattern called the square twist is the basis of a microscopic switch that Cornell physicists say could lead to origami-inspired materials and machines.
Simulations provide new insight into emerging nanoelectronic device
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential ...
Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Bacteria 'hotwire their genes' to fix a faulty motor
Researchers at the University of York are part of a team of scientist that has discovered how bacteria can restart their 'outboard motor' by hotwiring their own genes.
Nano switch could store memory using coordinated 'dance' of atoms
Switching superconductivity by light
A research team led by Prof. Hiroshi M. Yamamoto of the Institute for Molecular Science, National Institutes of Natural Sciences has developed a novel superconducting transistor which can be switched reversibly ...
