NewsPlankton may reveal ocean history - and even predict trends in chronic human illness
Tapping an almost century-long survey, University of California San Diego School of Medicine researchers say marine plankton may offer way to monitor historical marine pollution trends; and perhaps be used to predict trends in childhood and adult chronic illnesses.

NewsScientists test Raman spectroscopy as diagnostic tool for Lyme disease
Two Texas A&M University scientists are developing a test for Lyme disease that’s both more accurate and more efficient than the current test.
-
NewsCRISPR self-destruct protein may yield new tests for many viruses
A recently discovered protein has been found to act as a kind of multipurpose self-destruct system for bacteria, capable of degrading single-stranded RNA, single-stranded DNA and double-stranded DNA and holding potential for the development of at-home diagnostic tests for a wide range of infectious diseases.

NewsSimple nasal swab can provide early warning of emerging viruses
Testing for the presence of a single immune system molecule on nasal swabs can help detect stealthy viruses not identified in standard tests, Yale researchers have found.
-
NewsNew mode of horizontal gene transfer between maternal and infant gut microbiome uncovered
Researchers have discovered a new mode of vertical mother-to-infant microbiome transmission, where microbes in the maternal gut shared genes with microbes in the infant gut during the perinatal period starting immediately before birth and extending though the first few weeks after birth.

NewsNew mapping tool delivers first accurate tuberculosis genome
Researchers have developed a novel genome assembly tool that could spur the development of new treatments for tuberculosis and other bacterial infections.
-
NewsPoor gut health may drive multiple sclerosis — but better diet may ease it
Researchers have traced a previously observed link between microscopic organisms in the digestive tract — collectively known as the gut microbiome — and multiple sclerosis (MS).

NewsResearchers patent synthetic arsenic-based antibiotic originating in soil bacteria
Florida International University researchers have moved a step closer to producing synthetic arsenic-based drugs in their quest to solve an urgent worldwide health problem ―the growing number of infections that have become antibiotic-resistant.
-
NewsBacterial speed of growth and metabolism can offer answers to inoculum effect
Scientists have discovered that interactions between how fast bacteria grow and the amount of energy or metabolism bacteria have can explain the inoculum effect for multiple antibiotics and bacteria species.
-
NewsLasso peptide points the way to new antibiotics for untreatable infections
Princeton Engineering researchers have isolated a compound that kills bacteria that can cause incurable infections.
-
NewsOlfactory viral inflammation linked to accelerated onset of Alzheimer’s disease
Viruses can inflame and disrupt connections between the olfactory system, which governs the sense of smell, and the part of the brain associated with memory and learning, possibly accelerating the onset of Alzheimer’s disease, according to a new study.

NewsStudy reveals how plague spreads through wild rodent populations
Mathematical modeling reveals how fleas with early-stage Yersinia pestis infections are insufficient to drive epizootic outbreaks but can help promote a low level of enzootic plague.
