NewsCan gut microbes save patients from chemotherapy side effects?
Intestinal microbes that survive chemo can rid the gut of excess chemo drugs and produce a vitamin that helps to stem nausea, a new study reveals.

NewsSelenium exposure during pregnancy may reduce childhood streptococcal infections
Higher maternal selenium levels during pregnancy were associated with a lower risk of streptococcal infections in children, a new study shows, suggesting a potential protective effect.

NewsSegregation fuels faster spread of infectious diseases, study finds
Structural inequalities, including wealth inequality and social segregation, not only make certain groups more vulnerable during public health crises but also accelerate the spread of infectious diseases through society, according to a team of international researchers.

NewsCucumber green mottle mosaic virus breakthrough: uncovering novel antiviral strategy by hijacking host proteins
Researchers have made a groundbreaking discovery in their study of the Cucumber Green Mottle Mosaic Virus (CGMMV). CGMMV utilizes the host cytosolic fructose-1,6-bisphosphatase (FBPase) to catalyze the formation of BMCs via liquid-liquid phase separation (LLPS).

NewsMicrobial pioneers: how bacteria shape dental implant health from day one
A new study suggests that the earliest microbes to colonize a dental implant may determine its long-term fate. Using high-resolution genomic sequencing and a 12-week clinical timeline, scientists tracked how microbial ecosystems form around new dental implants.

NewsAdvanced genomics study improves detection of hard-to-find diarrheal infections
A study has used advanced genetic and genomic techniques to offer a major step forward in understanding and diagnosing infectious intestinal diseases. It analysed more than 1,000 stool samples from people with diarrhoeal illness to harness two cutting edge tools.

NewsThe hidden drivers of aging: microbial influence on genomic stability and telomere dynamics
A new review synthesizes current evidence on how microbial dysbiosis accelerates aging by disrupting genomic integrity and telomere dynamics, while also exploring therapeutic strategies to promote healthy longevity.

NewsBlood eosinophil count is associated with Pseudomonas aeruginosa infection but not the efficacy of inhaled tobramycin
A study has demonstrated that blood eosinophil counts (BECs) correlate with the disease severity, lung function, exacerbations in bronchiectasis, a chronic airway suppurative disease.
-
NewsBiodiversity in Antarctic soils may be greatly underestimated after surprising discovery
Researchers have shown that previously unknown apparent mutualisms allow biodiversity to flourish to an unexpected degree in an extreme habitat: weathered debris in front of a glacier in Antarctica.

NewsCold sore viral infection implicated in development of Alzheimer’s disease
Symptomatic infection with the virus responsible for cold sores around the mouth–herpes simplex 1, or HSV-1 for short—may have a key role in the development of Alzheimer’s disease, suggests a large pharma industry-funded US study.
-
NewsScientists uncover key clues to how a viral infection can lead to arthritis-like disease
By studying Chikungunya virus, scientists have shed light on how immune responses to viral infections may lead to persistent symptoms of autoimmune disease.
-
NewsSurvival trick: Pathogen taps iron source in immune cells
The body defends itself against pathogens by depriving them of vital iron. However, researchers have discovered that Salmonella bacteria specifically target iron-rich regions within immune cells to replicate, evading the immune defense.
-
NewsBiosynthetic pathway discoveries mean we can halve the price of costly cancer drug
Researchers have identified the enzymes responsible for the two critical final steps in the biosynthetic pathway that makes the chemotherapy drug Taxol active as a drug, potentially opening it up to biotech based production.
-
NewsGut bacteria and acetate offer a great combination for weight loss
Researchers have discovered a new way to reduce obesity - supplying the gut with extra acetate reduces fat and liver mass in both normal and obese mice, as long as bacteria of the Bacteroides species is also present in the gut.
-
NewsResearchers reveal how microbes can swim without a brain
Many microorganisms can move in a goal oriented way in liquids, despite the lack of a complex nervous system. New research explains the behaviour of microorganisms, and could also enable nanobots to move in a targeted manner.
-
NewsCommon drugs can help viruses spread
JAK inhibitors are often prescribed for autoimmune diseases and inflammatory conditions such as rheumatoid arthritis, but scientists have found they also weaken the body’s natural defences against viruses.
-
NewsResearch team traces evolutionary history of bacterial circadian clock on ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, researchers studied ancient timekeeping systems. They examined the oscillation of the clock proteins in modern cyanobacteria, comparing it to the function of ancestral Kai proteins.

NewsCould nanoplastics in the environment turn E. coli into a bigger villain?
New research suggests certain nanoplastics may make foodborne pathogens more virulent. Nanoplastics with positively charged surfaces were more likely to cause physiological stress in E. coli O157:H7, making them pump out more Shiga-like toxin.

NewsHow the Epstein-Barr virus promotes its spread within the body
Researchers have discovered that the Epstein-Barr virus (EBV) increases the ability of infected immune cells to migrate. In this way, the pathogen promotes its spread in the body – a discovery that may have therapeutic implications.

NewsGenomic data shows widespread mpox transmission in West Africa prior to 2022 global outbreak
Mpox was transmitted among humans in Nigeria for eight years before sparking the international outbreak in 2022. Using genomic tracing, the researchers estimate that the virus’s ancestor first emerged in southern Nigeria in August 2014.
