New research, headed by microbiologists from the University of Georgia, show for the first time that Salmonella – a widespread and often deadly bacterial pathogen – use molecular hydrogen to grow and become virulent. The discovery represents a way that diseases caused by Salmonella and other enteric infections could be lessened or even eliminated.
The research, just published in the journal Infection and Immunity, was led by Rob Maier, Georgia Research Alliance Eminent Scholar and Ramsey Professor of Microbiology at UGA. Other authors of the paper from UGA were and researcher Adriana Olczak and research coordinator Susan Maier; and Shilpa Soni and John Gunn from Ohio State University. "This builds on our earlier findings that major human pathogens are using an unexpected energy source," said Maier. "This new work expands our knowledge that molecular hydrogen is very important in the process of diseases caused by these organisms."
Such enteric pathogens as Salmonella are responsible for an estimated 2 million deaths a year and cause millions more cases of diarrheal illnesses, even in developed countries. Maier was the first to discover that hydrogen is not lost from the body as a waste product, as researchers previously thought, but remains at substantial levels and is an energy source for pathogenic bacteria. This knowledge that human pathogens can grow on hydrogen while residing in an animal may have profound implications for the treatment of some diseases.

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:...
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,...
