New Technique Using Nanoparticles may Selectively Repress Unwanted Immune Reactions

The human immune system is remarkably efficient, but sometimes its attack is misdirected, leading to allergies, autoimmune diseases and rejection of transplant organs and therapeutic drugs. Current immune suppressants have major drawbacks, but a team from The Scripps Research Institute (TSRI) has demonstrated a new technique that may lead to a better way to selectively repress unwanted immune reactions without disabling the immune system as a whole.

Fluid-Enhanced Crystal Engineering Printing Process Improves Organic Electronics

Through innovations to a printing process, researchers have made major improvements to organic electronics—a technology in demand for lightweight, low-cost solar cells, flexible electronic displays and tiny sensors. The printing method is fast and works with a variety of organic materials to produce semiconductors of strikingly higher quality than what has so far been achieved with similar methods.

Magnetic Force Microscopy Helps Observe Skyrmions

A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists at the Technische Universitaet Muenchen (TUM), the Technische Universitaet Dresden and the University of Cologne found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased.

Olympus Introduces New Laser Microscope for 3D Surface Measurement

The LEXT OLS4100 3D measuring laser microscope uses laser scanning to perform non-contact 3D measurement of complex surface features on electronic devices and other samples. As with current Olympus models, the LEXT OLS4100 guarantees both repeatability*1 and accuracy*2, while also being capable of high-resolution observation and highly accurate measurement over a wider area.

Fluctuation X-ray Scattering Shows Potential for Determining Behavior of Protein Mixtures

To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs.
