An innovative vaccine against tuberculosis has shown promise in persons with HIV, researchers from Dartmouth Medical School and the National Public Health Institute of Finland report in the Nov. 7 issue of the journal AIDS.
An international team led by DMS infectious disease expert Dr. C. Fordham von Reyn, professor of medicine, found that the new booster, a killed vaccine, enhanced the TB immunity of HIV patients. Their weakened immune systems make the current TB vaccine, which is a live vaccine, more risky.
In most countries where TB is widespread, children generally receive a vaccine made from live Mycobacterium bovis, Bacille Calmette-Guerin (BCG) that has been used to reduce the risk of TB for more than half century. Despite the widespread use of BCG, TB has been growing dramatically in the world, fueled by the increased susceptibility of HIV-infected people to TB.
TB remains the largest cause of death worldwide from any single infectious disease, according to the National Institute of Allergy and Infectious Diseases, which calls it "the major attributable cause of death" in HIV/AIDS patients.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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...
