Low-calorie sweetener does not seem to increase cancer risk in US adults

A recent study claims that the intake of low-calorie sweetener sweeteners does not increase the risk of cancer-related death. However, it may increase the risk of obesity and diabetes.

The binding and functional serologic responses to COVID-19 vaccination in children with history of MIS-C

Researchers evaluated the serological responses elicited by COVID-19 vaccinations in children who developed MIS-C following a previous SARS-CoV-2 infection.

New York sewer rats are easily infected by SARS-CoV-2, according to new study

Researchers evaluated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure among rats inhabiting New York City (NYC) during the fall of 2021.

Study shows no undetected monkeypox virus transmission before May 2022 in Rotterdam and Amsterdam

Researchers investigated whether undetected human monkeypox virus transmission occurred before Rotterdam and Amsterdam's first documented monkeypox cases.

23 Nov 2022

Fungi detected in 35 cancer types, often intracellular

In a recent article published in the journal Cell, researchers found fungal deoxyribonucleic acid (DNA) and cells at low abundances across many human cancers, with cancer type-dependent variations in fungus community composition and fungal-bacteriome interactions.

Myocarditis after COVID vaccination is rare but higher in younger males

In a recent study published in the Canadian Medical Association Journal, researchers observed the incidence of myocarditis following messenger ribonucleic acid (mRNA)-based vaccination against coronavirus disease 2019 (COVID-19). Additionally, they compared their estimates with expected rates based on the historical rates assessed before the COVID-19 vaccination rollout in British Columbia (BC), Canada.

Novel mRNA vaccines encoding Monkeypox virus proteins show promise in preclinical studies

In a recent study posted to the bioRxiv* preprint server, researchers in China demonstrated the efficacy of three messenger ribonucleic acid (mRNA) technology-based Monkeypox virus (MPXV) vaccines in combating a lethal Vaccinia virus (VACV) challenge in mice models.

Study investigates spread of Klebsiella superbug between humans and the environment

An international team of scientists investigating transmission of a deadly drug-resistant bacteria that rivals MRSA, has found that whilst the bugs are found in livestock, pets and the wider environment, they are rarely transmitted to humans through this route.

Ultrapotent IgM antibodies isolated from a pregnant woman with Zika virus show promise as an immunotherapy

Zika virus (ZIKV) infection is a potentially teratogenic illness, causing up to one in seven infants born to infected mothers to suffer neurodevelopmental deficits. A new study published in the journal Cell shows that some mothers escape injury to their babies because they develop a highly potent neutralizing antibody.
