NewsResearchers uncover key biomolecule involved in whooping cough infection
Researchers have identified a new complex-carbohydrate biomolecule, or glycan, that plays a key role in the nasal colonization of the Bordetella bacteria responsible for whooping cough.

NewsCancer therapies show promise in combating tuberculosis
A study has identified a combination of medications that may improve blood flow within granulomas, tight clusters of white blood cells formed by the body’s immune system in response to tuberculosis infection, benefiting drug delivery.

NewsNew vaccine against a highly fatal tropical disease – and potential bioterror weapon – demonstrates efficacy in animal studies
In a mouse study, researchers tested a vaccine against the bacterium that causes melioidosis and found it was highly protective against the disease, which is endemic in many tropical areas.

NewsMaize genes control little helpers in the soil
Researchers studying different local varieties of maize have discovered that the genetic makeup of the plants also helps to influence which microorganisms cluster around the roots.

NewsScientists close in on TB blood test which could detect millions of silent spreaders
Scientists have taken a major step towards developing a blood test that could identify millions of people who spread tuberculosis unknowingly.
-
NewsNew classification of tuberculosis supports efforts to eliminate the disease
A new way to classify tuberculosis (TB) that aims to improve focus on the early stages of the disease has been presented by an international team.
-
NewsResearchers ask if active screening for tuberculosis among vulnerable populations is cost-effective
Scientists present the findings of their systematic review on active pulmonary TB screening programmes run between 2008 and 2023 in so-called high-risk groups living in low TB incidence countries.

NewsResearch uncovers a new path to drug diversity
By exploring protein evolution, scientists have found new “fusion sites” that enable faster and more targeted drug development.

NewsAfrican catfish skin mucus yields promising antibacterial compound
Scientists report they have extracted a compound with powerful antibacterial properties from the skin of farmed African catfish.

NewsFor each 10% increase of certain bacteria type in the gut microbiome, the risk of hospitalisation for infections falls by up to a quarter
A study of two large European patient cohorts has found that for every 10% increase in butyrate-producing bacteria in a patient’s gut, the risk of hospitalisation for any infection falls by between 14 and 25% across two large national cohorts. The

NewsSigns of life potentially detectable in single ice grain emitted from extraterrestrial moons
A new lab-based study shows that individual ice grains ejected from the moons of Saturn and Jupiter may potentially contain enough material for instruments headed there in the fall to detect signs of life, if such life exists.

NewsResearchers invent artificial intelligence model to design new superbug-fighting antibiotics
Researchers have invented a new generative artificial intelligence model which can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.
-
NewsNon-culturable Legionella identified with sequencing
Researchers have described a cost-effective approach for using whole genome sequencing to identify Legionella pneumophila that doesn’t require culturing.
-
NewsStudy reveals possible triggers for inflammatory bowel disease
A new study finds a complex interplay between diet, genes, and the gut microbiota that could explain why IBD develops.
-
NewsMembrane-producing enzyme offers promising target
The enzyme LpxC, which catalyzes the first irreversible step in the biosynthesis of the outer membrane of Gram-negative bacteria, is a highly promising target for the development of antibiotics.
-
NewsNew blood test cuts infection diagnosis time from months to hours
Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours.
-
NewsBacteria subtype linked to growth in up to 50% of human colorectal cancers
A new study suggests that a subtype of Fusobacterium nucleatum underlies colorectal cancer growth in humans and could be useful in screening and treatments.

CareersLife-changing and unforgettable: Dami and Jisa report back on ABRCMS
Students Dami Okeyoyin and Jisa Salim report back after attending the Annual Biomedical Research Conference for Minoritized Scientists (ABRCMS) 2023 in Phoenix, Arizona in November with AMI trustee Dr Emmanuel Adukwu.

NewsProtein found in human sweat may protect against Lyme disease
Researchers also found that a variant of the protein is not as protective against the bacterium and increases susceptibility to the disease.

NewsResearchers investigate how freshwater diatoms stay in the light
Scientists sampled the ice-covered (in 2019) and ice-free (in 2020) winter waters of Lake Erie to learn how diatoms are responding to changing environmental conditions.
