AIDS immunisation is still to be improved. Russian scientists suggest that rectal vaccination could be the most effective prevention of HIV transmission. The work is supported by the Interdepartmental Research and Technical Program "Vaccines of new generation and medical diagnostic systems of the future".
Researchers all over the world strive to obtain a vaccine preventing AIDS. Most promising are DNA-vaccines, which contain genes of human immunodeficiency virus. These genes function within the human body and synthesize certain viral proteins harmless to human health, and the immune system produces antibodies to those proteins and becomes resistible to a whole virus in case if the latter appears.
The DNA-vaccine is usually prescribed per-orally. One needs to eat quite a lot of DNA, which is very expensive, in order to induce an adequate immune response. Intramuscular injections can cause only a very weak and short-term response. Hence, scientists search for another route of DNA-vaccination that would require a low dose and provide a high specific immune response.

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,...
