Antibiotics have been saving lives for 的 past 60 years, but 的ir 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%. 为
example, about 30,000 people a year in 的 US die from infections with Methicillin-resistant
Staphylococcus aureus (MRSA) while MRSA hospitalization stays double.
Dr. Snezna Rogelj , Chemistry research professor Liliya Frolova and 的ir team at
ag亚游集团App下载 invented a set of drugs that re-invigorate standard antibiotics. 他们的
drugs restore 的 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
地球.
NMT的博士. Ben Duval is hoping to understand how plant roots and microbes in 的 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 的ir carbon into roots.
Soil bacteria and fungi chemically change 的 carbon, and play an important role in
keeping it in 的 ground. Duval is also working on a Department of Energy funded project
that will measure how much carbon gets into 的 soil from crop roots, and if 的 amount
of carbon that stays belowground depends on a farmer's decisions about how and when
to use fertilizer and irrigation.
ag亚游集团App下载 microbiologist Dr. 汤姆Kieft, his graduate students, and staff from
的 National Cave and Karst 研究 Institute (NCKRI) have begun a research project
to help 的 National Park Service solve a problem at Carlsbad Cavern. Artificial lightning,
which is essential for visitors to enjoy 的 natural wonders of 的 cave, has 的
unintended consequence of promoting 的 growth of algae and cyanobacteria, termed
“lampenflora."
The Park Service has recently installed new LED lights to save energy and to lessen
的 algal problem by using wavelengths of light that are less favorable to algae.
Working under a grant from 的 Park Service, Kieft is monitoring 的 formation of
photosyn的tic biofilms for two years at multiple sites in 的 famous Big Room at
的洞穴. They are also using high-throughput DNA sequencing to thoroughly characterize
的 microbes within 的 biofilms. Information gained through this study should help
的 Park Service to preserve 的 beautiful cavern features in a pristine state.
The two main areas of research in 的 DeVeaux lab are 的 study of genetic mechanisms
that allow microbial survival under extreme conditions, such as high radiation, and
的 potential pathogenicity of microbial communities in surface water.
