NewsThermo Fisher Scientific launches new color-based culture media to help detect Candida infections faster
Thermo Fisher Scientific today announced the launch of Thermo Scientific™ Brilliance™ Candida 2 Agar and Spectra™ Candida Agar, new color-based (chromogenic) culture media to help laboratories quickly detect and differentiate clinically important Candida species.

NewsBacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. A new study shows for the first time how gut bacteria break down parts of an allergenic food and influence how a person reacts to peanuts.

NewsGrowing buildings in space: researchers test fungi as construction material for moon, Mars
A NASA-funded project will investigate whether certain fungi can be combined with regolith — loose rock and soil found on the surface of the moon and other planets — to create materials that could one day support construction in places other than Earth.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.

NewsProlonged drought linked to instability in key nitrogen-cycling microbes in Connecticut salt marsh
A prolonged drought in southeastern Connecticut reduced the stability of microorganisms responsible for a critical step in the nitrogen cycle in a coastal salt marsh, according to new research.

NewsNew tool reveals the secrets of HIV-infected cells
Scientists have developed a novel tool—named HIV-seq—for profiling the features of rare HIV-infected cells from people with HIV. Using the new tool, they’ve found key differences in people’s HIV-infected cells before versus after starting antiretroviral therapy.

NewsResearchers find a gentler way to treat aggressive gum disease
Researchers have discovered that the primary bacterium driving gum disease carries an internal “genetic brake” that controls its own aggression. By locking this brake in place, future treatments could silence the pathogen while leaving beneficial bacteria untouched.

NewsLife forms can planet hop on asteroid debris – and survive
The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact, a study shows. It means microorganisms can survive more extreme conditions than previously thought, including launch across space after major impacts.

NewsTestosterone increases severity of bacterial skin infections
Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study is the first to reveal testosterone, present at higher levels in males, as a key driver of infection.

NewsHuge toll: Bird flu rampant among black vultures
More than four out of every five dead black vultures examined by University of Georgia researchers tested positive for highly pathogenic avian influenza, according to a new study. Their indiscriminate scavenging appears to sustain transmission of the virus beyond the typical bird flu season.

NewsFecal transplants from older mice significantly improve ovarian function and fertility in younger mice
A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome of the gut and ovarian health and function.

NewsCell-free DNA offers early warning for bloodstream infections in kids with leukemia
Researchers show that microbial cell-free DNA sequencing can predict bloodstream infections in children with leukemia days before the symptoms appear. Plasma microbial cell-free DNA sequencing (mcfDNA-Seq) offer a potential approach to protecting vulnerable patients by allowing treatment to start before the patient gets sick.

NewsNew study demonstrates universal newborn cCMV screening leads to earlier detection and increased identification of mild hearing loss
A new retrospective cohort study examining the impact of Minnesota’s first-in-the-nation mandated universal newborn screening for congenital cytomegalovirus (cCMV) shows that universal screening significantly decreased the age at first audiology visit and increased identification of mild hearing loss in infants.

NewsFungi could transform leftovers into lifelines
A new paper outlines an ’emerging circular fungal biorefinery’ – a system in which low-value agricultural byproducts are converted through fungal fermentation into high-protein, nutrient-rich foods.
-
NewsScientists develop new gut health measure that tracks disease
Scientists have found that healthy and diseased digestive systems behave like two distinct ecological states, driven not by individual microbes but by how entire bacterial communities compete and cooperate.

NewsWater bears reveal potential for adapting and protecting Martian resources
Microscopic tardigrades help inform how simulated Martian soil might support plant life and mitigate contaminants shedding from human explorers, researchers report.

NewsNanoplastics can interact with Salmonella to affect food safety, study shows
Researchers investigating what happens when nanoplastics (polystyrene) interact with Salmonella discovered an increased expression of virulence-related genes. The bacteria also formed thicker biofilms, which indicates they are becoming more virulent.

NewsTrust your gut to heal your brain
Researchers have found that short-term antibiotic treatment significantly reduced neuroinflammation and neurodegeneration following traumatic brain injury (TBI) by altering the gut microbiome in animal models.

NewsImaging technique is step towards needed treatments for hantaviruses in new molecular ma
Researchers have produced a detailed blueprint, the highest resolution yet, for a protein complex the Andes virus uses to infect host cells. The new detailed structural information enabled the researchers to produce a vaccine candidate that caused mice to produce neutralizing antibodies against the Andes virus.

NewsGut health home-testing kit outcomes vary between kits and manufacturers
Results and health assessments from gut microbiome home-testing kits vary whether they are produced by the same or different manufacturers. The findings on testing kits from seven providers highlight the need for caution when interpreting or acting on test results, according to the authors.
