Biologists studying the development of plant roots, a general basic model for tissue development, are uncovering new pieces of the puzzle of how one root cell sends its molecular instructions to another in the development process.
Researchers have found hints that the channels by which such molecules move between plant cells may also be mirrored in animal cells. Thus, discoveries about plant development may be more broadly applicable to understanding the fundamental processes of how complex tissues develop from a few cells -- one of the central mysteries in biology.
Duke University biologist Philip Benfey and his colleagues published their latest findings in the Oct. 26, 2004, issue of the journal Current Biology. Besides Benfey, other co-authors are Kimberly Gallagher of Duke, Alice Paquette of New York University and Keiji Nakajima of the Nara Institute of Science and Technology in Japan. Their research was supported by the National Institutes of Health.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
