Morphogens are molecules that play a role in the development of organs
Scientists at Cincinnati Children’s Hospital Medical Center believe they have answered some critical questions that address how signaling molecules, called morphogens, work. Morphogens are secreting signaling molecules that play a key role in the formation of the shape and size of organs. For example, these molecules play a role in determining the bean-like shape of human kidneys. But when these molecules malfunction, they can lead to organ defects and cancers. This study provides insights into the mechanisms of organogenesis and could have implications for treating organ defects and cancers.
For years scientists at Cincinnati Children’s and elsewhere have sought to determine how morphogens work. In a new study published in the October 15 issue of the journal Cell, Xinhua Lin, PhD, an assistant professor of developmental biology at Cincinnati Children’s, concluded that morphogens work by "diffusion." "These findings provide new insight into the understanding of the mechanisms that control the function of morphogens," Lin said. "In order to treat diseases related with morphogen malfunctions, scientists must first understand the mechanisms that trigger diseases. This understanding can lead to new insight into the possibility of developing new strategies to treat related diseases."

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
