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.

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
