Antibiotics have been saving lives for the past 60 years, but their widespread use
has resulted in evolution of highly drug-resistant bacteria. Multi-drug resistant
bacteria are now a global threat as fatality rates in some cases approach 50%. For
example, about 30,000 people a year in the US die from infections with Methicillin-resistant
Staphylococcus aureus (MRSA) while MRSA hospitalization stays double.
Dr. Snezna Rogelj , Chemistry research professor Liliya Frolova and their team at
色狐入口 Tech invented a set of drugs that re-invigorate standard antibiotics. Their
drugs restore the activity of seven diverse classes of antibiotics against a wide
variety of drug-resistant and drug-sensitive bacteria, including MRSA, VRE and CRE.
In combination, such drug-resistant bacteria are once again susceptible to low doses
of well tested, clinically proven and widely prescribed antibiotics.
Heavy traffic and smoke billowing from factories is what most people associate with
carbon gases and climate change, but soils hold more carbon than all plant life on
Earth.
NMT's Dr. Ben Duval is hoping to understand how plant roots and microbes in the soil
help store that carbon belowground. Along with graduate students, Duval is studying
what triggers native New Mexican pinon and juniper trees to make seeds in our dry
ecosystems, a process that requires plants to put some of their carbon into roots.
Soil bacteria and fungi chemically change the carbon, and play an important role in
keeping it in the ground. Duval is also working on a Department of Energy funded project
that will measure how much carbon gets into the soil from crop roots, and if the amount
of carbon that stays belowground depends on a farmer's decisions about how and when
to use fertilizer and irrigation.
色狐入口 Tech microbiologist Dr. Tom Kieft, his graduate students, and staff from
the National Cave and Karst Research Institute (NCKRI) have begun a research project
to help the National Park Service solve a problem at Carlsbad Cavern. Artificial lightning,
which is essential for visitors to enjoy the natural wonders of the cave, has the
unintended consequence of promoting the growth of algae and cyanobacteria, termed
"lampenflora."
The Park Service has recently installed new LED lights to save energy and to lessen
the algal problem by using wavelengths of light that are less favorable to algae.
Working under a grant from the Park Service, Kieft is monitoring the formation of
photosynthetic biofilms for two years at multiple sites in the famous Big Room at
the Cavern. They are also using high-throughput DNA sequencing to thoroughly characterize
the microbes within the biofilms. Information gained through this study should help
the Park Service to preserve the beautiful cavern features in a pristine state.
The two main areas of research in the DeVeaux lab are the study of genetic mechanisms
that allow microbial survival under extreme conditions, such as high radiation, and
the potential pathogenicity of microbial communities in surface water.
