NewsCell wall of Lyme disease pathogen causes lingering symptoms
The National Institutes of Health awarded a College of Agriculture and Life Sciences researcher $2.7 million to understand how the cell wall of the Lyme disease-causing pathogen makes people sick.

NewsHigh-res map of the human placenta reveals COVID virus hideouts
Researchers have developed a high-resolution map of the human placenta visualizing an array of different immune microenvironments in healthy placentas from uninfected pregnancies, and those from pregnancies affected by COVID infections.

NewsInvestigational three-month TB regimen is safe but ineffective
The first clinical trial of a three-month tuberculosis (TB) treatment regimen is closing enrollment because of a high rate of unfavorable outcomes with the investigational course of treatment.

NewsWidely consumed vegetable oil leads to an unhealthy gut
Researchers examined the gut of mice that were consistently fed a diet high in soybean oil for up to 24 weeks in the lab, finding beneficial bacteria decreased and harmful bacteria increased — conditions that can lead to colitis.
-
NewsPackaging tray can signal Salmonella contamination before food is unwrapped
Researchers have created a new packaging tray that can signal when Salmonella or other dangerous pathogens are present in packages of raw or cooked food such as chicken.
-
NewsArtificial cells show that ‘life finds a way’
Scientists studying a synthetically constructed minimal cell that has been stripped of all but its essential genes have found it can evolve just as fast as a normal cell.
-
NewsScientists develop all-species Covid test
In an advance that will help scientists track coronavirus variants in wild and domesticated animals, researchers report they can now detect exposure to the SARS-CoV-2 virus in any animal species.
-
NewsScientists uncover secrets of bacteria threatening Vidalia onion production
Researchers have confirmed which genes in the bacterial pathogen Pantoea ananatis high virulence cluster are essential and which genes contribute partially to a disease that causes rotting symptoms in Vidalia onions.

NewsNew CRISPR gene editing approach opens up more of the genome
Scietnists have come up with a new way to identify diverse CRISPR RNA variants that can specifically home in on challenging areas of DNA to target for editing. The new approach opens up more of the genome for editing, enabling the repair of mutations associated with more diseases.
-
NewsNearly half of TB cases in prisons worldwide go undetected
In the first global assessment of tuberculosis among incarcerated people, a new study found consistently high TB case rates and low case detection in prisons.

NewsImmune-boosting therapy helps honey bees resist deadly viruses
Scientists have successfully tested a novel way of boosting honey bees’ immune systems to help them fend off deadly viruses, which have contributed to the major losses of the critical pollinator globally.
-
NewsCRISPR-like system in eukaryotes can edit the human genome
The first RNA-guided DNA-cutting enzyme found in eukaryotes, Fanzor could one day be harnessed to edit DNA more precisely than CRISPR/Cas systems.
-
NewsNanoparticle may improve mRNA cancer vaccines
Tests in mice with melanoma and colon cancer show the tiny particle creates an ‘army’ of immune cells that carry vaccine’s instructions, say the researchers.
-
NewsMolecular insights may inform new treatments for drug-resistant TB
Researchers have used state-of-the-art imaging to examine two new compounds that target ATP synthase, potentially stopping TB bacteria from producing the energy they need to survive.
-
NewsSquash bugs devour each other’s poo to stock their microbiome
Researchers have found that, to acquire healthy gut bacteria, young squash bugs innately seek out and eat the faeces from older squash bugs.
-
NewsDigital test directly measures HIV viral load
Researchers have developed a time and cost-efficient digital assay that can directly measure the presence of HIV in a single drop of blood.
-
NewsResearchers can use ultrasound to control orientation of small particles, including bacteria
Using ultrasound technology and a nozzle, scientists have separated, controlled and ejected different particles based on their shape and various properties, with implications for drug delivery and bioprinting.
-
NewsAutism-specific metabolic pathways linked to gut microbes
A reanalysis of previous studies has identified autism-specific metabolic pathways associated with particular human gut microbes - these were also seen elsewhere in autistic individuals, from their brain-associated gene expression profiles to their diets.
-
NewsResearchers reveal how Leishmania parasite uses immune cells as Trojan Horse
A new study found that the parasite targets a receptor on the surface of the neutrophil to gain access to the cell, and once inside the parasite resists the neutrophils’ pathogen-killing molecules.

NewsRule-breaking anoxic bacteria infected with viruses
Researchers investigating why green and purple bacteria in northeast Washington didn’t obey the usual rules found they had genes in their metagenome that came from viruses.
