In COVID-19 clinical update #72, Daniel Griffin covers long term symptoms in children, outcomes for MIS-C, recent guidance from the American Academy of Pediatrics, a large well traced outbreak of delta variant, low dose mRNA vaccination generates durable T cell memory and antibodies, protective immunity in recovered patients, assessment of BinaxNOW, no effect of oral azithromycin, post-discharge symptoms in Nigeria, and therapeutics for low and middle income countries. post
On this episode, broadening of immune responses to SARS-CoV-2 after mRNA vaccine booster to ChAdOx1 nCoV-19, five-fold underestimation of the number of cases in the US during the first six months of the pandemic, and a monoclonal antibody that broadly neutralizes many different sarbecoviruses. post
The TWiM folk explore disruption of a Burkholderia intracellular niche by a cell death program, and an increase in Brucella infectiousness after intracellular passage. post
The Team with Invincible Values discusses whether dogs or cats passively carry SARS-CoV-2 on hair and foot pads, maternal to fetal transfer of antibodies in infected or vaccinated pregnant women, and evidence that retroviruses infected cetaceans before and after they moved into the oceans. post
In COVID-19 clinical update #71, Daniel Griffin reviews updated school and child care guidance from CDC, transmission in schools, accuracy of lateral flow assays, update to J&J/Janssen vaccine EUA to include GBS, interim immunogenicity of Ad.26.CoV2.s, effectiveness of mRNA vaccines to prevent hospitalization, Bamlanivimab plus Etesevimab for mild or moderate disease, and a meta-analysis of ivermectin results. post
While perceptual constancy requires the brain to maintain a stable representation of sensory input, TWiN explores a study showing that odor-evoked responses in the olfactory cortex drift over periods of days to weeks. post
In this episode, how polysaccharides keep cyanobacteria afloat in the oceans so that they can carry out photosynthesis, and a symbiotic bacterium that protects honey bees from fungal infections. post
Nels and Vincent discuss the identification of novel bat coronaviruses that shed light on the evolution of SARS-CoV-2, dating the first cases of COVID-19 to mid-November 2019, and recovery of deleted genome sequences from early in the Wuhan outbreak. post
Foodie TWiM reveals that bacteria in human saliva are major components of Ecuadorian indigenous beers, and an unusual E. coli that produces atypical light cream-colored colonies in chromogenic agar. post
On this episode, Vivianne gives a primer on glial cells, with the goal of thinking about the central nervous system holistically and appreciating the different cell types that contribute to its function. post
On this episode of Immune, we answer listener questions about CAR-Macs, complement and COVID-19, sleep and the immune system, caving and the immune system, germinal centers, COVID-19 vaccines and much more. post
TWiM continues its food arc with an examination of the effect of peroxyacetic acid spray on the microbiome and sensory properties of beef, and explores asymmetry of the cell division machinery during sporulation. post
Christina returns to the TWiP trifecta to solve the case of the Beachgoer with Red Lines on Her foot, and an experimental malaria vaccine based on the junctional region of the circumsporozoite protein displayed on a virus-like particle. post
Nels and Vincent explain a new method for calculating the most recent common ancestor of SARS-CoV-2, which concludes that the ancestral virus was circulating in October/November 2019, before its first detection in China. post
Mauro Costa-Mattioli joins TWiN to discuss how his laboratory dissects the contribution of host genetics and the microbiome in complex neurodevelopment disorders such as autism spectrum disorders. post
TWiP solves the case of the Long Island Man with Unilateral Eye Pain, followed by a discussion of how enteric helminth coinfection enhances host susceptibility to West Nile virus by a tuft cell-IL-4 receptor signaling axis. post
Michael Nitabach joins TWiN to discuss the finding that the nematode C. elegans, which do not have eyes, can discriminate between colors to guide foraging decisions and move them away from harmful bacteria that produce a blue-pigment toxin. post
Audun returns to help solve the case of the Ecuadorean Gentleman Treated for COVID-19, followed by a discussion of the interaction of Blastocystis with the intestinal microbiota and the immune system, and of course a new clinical case from Daniel. post
Nels and Vincent review a preprint demonstrating that changes in the genomes of the SARS-CoV-2 variants B1.351 and P.1 allow the viruses to reproduce in mouse cells in culture and in laboratory mice. post
On this episode of Immune, Cindy provides an update on CAR-T cell therapy of cancers and introduces two new approaches that utilize NK cells and macrophages and their use in treating solid tumors. post
Daniel joins Dickson and Vincent to talk about the Vertical Farm Institute, which provides advice and planning on the design and construction of indoor farms. post
In this episode of Virus Watch, we explore the finding that Zika virus infects the testis of mice, causing damage to the organ, reduced sperm production, and less fertility. The important question: does the same happen in humans? post
Dickson and Vincent speak with Robert Colangelo, founding farmer and CEO of Green Sense Farms, the world's largest commercial indoor vertical farm. post
