Tissue engineering has long held promise for building new organs to replace damaged livers, blood vessels and other body parts. However, one major obstacle is getting cells grown in a lab dish to form 3-D shapes instead of flat layers. Researchers have come up with a new way to overcome that challenge, by encapsulating living cells in cubes and arranging them into 3-D structures, just as a child would construct buildings out of blocks.
Researchers from Columbia University, Arizona State University, the University of Michigan and the California Institute of Technology (Caltech) have created and programmed robots the size of single molecule that can move independently across a nano-scale track.
While the laws of physics weren't made to be broken, sometimes they need revision. A major current law has been rewritten thanks to the three-port transistor laser, developed by Milton Feng and Nick Holonyak Jr. at the University of Illinois.
Nature and technology may seem worlds apart, but New York University Computer Scientist Dennis Shasha maintains that the natural world can bolster the capacity of today's most sophisticated machines. In Natural Computing: DNA, Quantum Bits, and the Future of Smart Machines, Shasha and co-author Cathy Lazere describe the work of 15 pioneers who have successfully harnessed nature's power in advancing technology.
A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular 'robot' made out of DNA to start, move, turn, and stop while following a DNA track.
Twenty-five years after the laser beam came to be, a historic meeting took place at Rice University that led to the discovery of the buckminsterfullerene, the carbon 60 molecule for which two Rice scientists won the Nobel Prize.
The 'European Inorganic Membrane Research Alliance' (EIMRA) aims to facilitate the transition from basic research to applications. In this way, EIMRA will contribute to the worldwide effort to enhance industrial efficiency and reduce carbon dioxide emissions.
A solution-phase process has been developed by CNM users from the University of California at Riverside, working collaboratively with the Nanophotonics Group, for synthesizing stable multifunctional colloidal particles composed of a superparamagnetic Fe3O4 core, a gold nanoshell, and a mesoporous silica outer layer.
All optics research requires precise alignment of optical components to ensure that light passes efficiently from one element to the next. At the micro-scale, however, the process is much more delicate and complicated. Now, an alignment mechanism integrated onto a silicon chip to allow quick and cheap optical optimization has been demonstrated.
In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world's entire output of silicon chips in a month. So says a Duke University engineer, who believes that the next generation of these logic circuits at the heart of computers will be produced inexpensively in almost limitless quantities.
