NewsIn the US Northeast, 50% of adult ticks carry Lyme disease carrying bacteria
A new study finds that 50% of adult blacklegged ticks in the US Northeast carry the bacteria that causes Lyme disease while 20% to 25% of the younger (nymph) blacklegged ticks carry the bacteria.

NewsChild undernutrition may be contributing to global measles outbreaks
A study of fully vaccinated children finds a link between stunted growth and weakened immunity, suggesting combatting child hunger could help prevent the disease’s spread.

NewsReview offers guidance to clinicians on animal-borne infections in the Canadian Arctic
A new review on zoonotic infections in the Canadian Arctic provides timely guidance to clinicians as the region experiences heightened global interest as well as climate change, which threatens the region and increases risk of disease transmission.

NewsChain reaction: HIV vaccines can lead to antibodies against antibodies
Scientists have discovered that repetitive HIV vaccinations can lead the body to produce antibodies targeting the immune complexes already bound to the virus—knowledge that could lead to better vaccines.

NewsThe hunt narrows for Ebola virus hosts
A cholesterol-trafficking receptor, Niemann-Pick C1 (NPC1), was identified for more efficient surveillance of host reservoirs of filoviruses, including Ebolaviruses. It narrows down the host species of the virus and links to the geographic information of pathogen emergence.

NewsPediatric investigation study examines the diagnostic potential of microbial cell-free DNA testing
A research study has found that plasma-based microbial cell-free DNA testing served as a safer and faster alternative to conventional microbiological diagnostic tests for pediatric ear, nose and throat (ENT) infections.

NewsChanges in microbiome predict risk for sexually transmitted disease
Researchers have found that bacterial vaginosis consists of two subtypes—one of which significantly increases the risk of developing chlamydia infections.

NewsBird flu is mutating - but antivirals still work
Researchers have identified nine mutations in a bird flu strain from a person in Texas. The bad news: this strain is more capable of causing disease and replicates better in the brain. Good news: approved antivirals are still effective.

NewsChickpea and pea tempeh under development as new plant-based protein foods
New research focuses on fermenting dry chickpeas and dry peas to create a new type of tempeh, traditionally made with soybeans. Preliminary research suggests meat alternatives may help offset the health risks of the Western diet.

NewsNew research provides insight into reduced COVID-19 vaccine efficacy in lupus patients
A recent study provides new insights into why the mRNA vaccines developed to fight COVID-19 in 2021 are less effective in patients with autoimmune diseases, highlighting that lupus patients may require tailored vaccination strategies.

NewsBeach guardians: How hidden microbes protect coastal waters in a changing climate
Coastal water quality is closely impacted by the microbial compositions living in groundwater within beach sands due to the rising sea level, a new study reveals.

NewsBacterial toxin offers hope to tackle soybean nematode pest
A new study reveals how genetically equipping soybean plants with bacterial toxin Cry14 could revolutionize the fight against the microscopic soybean cyst nematode. This approach has been implemented successfully to prevent SCN from feeding on soybean roots.

NewsGut bacteria in a chemical tug-of-war with the body
Researchers have identified a clever trick the body uses to keep gut microbial influence on the metabolism in check. In the intestines, the body modifies the microbial bile acids into a new family of derivatives, called BA-MCYs, using an enzyme named VNN1.
