Killing the disease without killing the patient is an old dilemma for doctors fighting cancer and some of the tougher microorganisms such as fungal infections in individuals with suppressed immune systems. Drugs have little effect when a patients own immune system isnt available to help, and these fungi can resist external radiation that would kill even a perfectly healthy human. But they can be easily killed by a very small dose of radiation inside their cells.
Monoclonal antibodies can be designed to deliver radiation to specific cell types while sparing surrounding tissue. These designer antibodies, armed with radioactive isotopes, have been found to be highly effective against some types of cancer, but the combination may also be useful in other types of serious disease. This technique is known as radioimmunotherapy (RIT).
A study appearing in the February issue of The Journal of Nuclear Medicine demonstrates that radioimmunotherapy (RIT) provides a new, highly effective way to kill Cryptococcus neoformans and Histoplasma capsulatum, the fungi responsible for fungal meningitis and pneumonia, using much smaller levels of radiation than required to kill the fungi by external radiation. The study used organism-specific monoclonal antibodies coupled with radioactive isotopes of bismuth or rhenium.

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,...
