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.

NewsHigh-efficiency gene-editing tool coaxes fungi into yielding their secrets
Using an approach that simultaneously modifies multiple sites in fungal genomes, Rice University chemical and biomolecular engineer Xue Sherry Gao and collaborators coax fungi into revealing their best-kept secrets, ramping up the pace of new drug discovery.

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.
-
NewsScientists identify infection-halting compound that can target hosts, not viruses
Researchers at UBC’s Life Sciences Institute have identified a compound that shows early promise at halting infections from a range of coronaviruses, including all variants of SARS-CoV-2 and the common cold.
-
NewsMachine learning tool figures out how many people are represented in a wastewater sample
A machine learning model has been developed that uses the assortment of microbes in wastewater to find out how many individual people they represent.
-
NewsMicrobiota transfer therapy boosts gut health in children with autism
Researchers have discovered that microbial taxa and genes that are important for microbial pathways associated with improvements in the physical and behavioural symptoms of autism spectrum disorder, improved following microbiota transfer therapy.
-
NewsPhase 2 trial of Ebola vaccines yields promising results
An international team of scientists has published the results of a large-scale randomized clinical trial in West Africa which confirms the safety of three vaccine regimens for Ebola and suggests an immune response is induced and maintained for up to 12 months.
-
NewsResearchers develop ingestible biobatteries that could allow new view of digestive system
Biobattery researchers have created a solution based on microbial fuel cells that would allow cameras to target the hard-to-reach small intestine, which winds around the human gut for an average of 22 feet.
-
NewsPotential drug takes aim at emerging Chikungunya virus
Researchers are developing what could become the first-ever treatment against the debilitating joint pain that can last months or years after becoming infected with the emerging Chikungunya virus.
-
NewsMolecules found in mucus could prevent cholera infection
MIT researchers have identified molecules found in mucus that can block cholera infection by interfering with the genes that cause the microbe to switch into a harmful state.
