The results of those trials, coupled with advances from other TB studies, have paved the way for the next 10 years of research on TB vaccines, a critical component of TB control efforts, note scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Their editorial, co-authored by NIAID Director Anthony S. Fauci, M.D., and Christine Sizemore, Ph.D., appears in the journal Tuberculosis to coincide with the publication of Tuberculosis Vaccines: A Strategic Blueprint for the Next Decade.
The new Blueprint on TB vaccines updates the original one, which was published in 2000 as the result of an NIH-sponsored workshop.
Since that time, TB researchers have assembled a significant pipeline of vaccine candidates and assessed them in clinical trials. However, to transform the field and help make licensure of new vaccines a reality, the editorial co-authors stress, scientists must investigate remaining fundamental questions, including the following:
Why does infection with the TB bacterium cause active disease in some people but not others?
Why does the current licensed TB vaccine, Bacille Calmette-Guérin, protect children more effectively than adults?
What immune responses must effective vaccines elicit to successfully protect against TB?
For more information about the original Blueprint published in 2000, see the NIAID news release announcing its publication. For more information about NIAID's TB research, visit the NIAID Tuberculosis Web portal.
NIAID conducts and supports research—at NIH, throughout the United States, and worldwide—to study the causes of infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at http://www.niaid.nih.gov.
About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research, and is investigating the causes, treatments, and cures for both common and rare diseases.

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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
