TWiM explores whether ‘rewilding’ is a way to get back our missing gut microbes, and failure of bacteriophage therapy due to the production of neutralizing antibodies. post
Kiran joins TWiV to discuss the findings of a team at Columbia University Medical Center on COVID-19 neuropathology, and the conclusion that SARS-CoV-2 does not reproduce in the central nervous system. post
In COVID-19 clinical update #73, Daniel Griffin reviews updated mask guidance from CDC, infections in public school district employees, effectiveness of vaccines against delta variant, antibody response after third vaccine dose in kidney transplant recipients, protection afforded by mRNA vaccines fully vaccinated people with and without prior infections, correlates of protection in nonhuman primates, lack of effectiveness of doxycycline, neurological manifestations of COVID-19, and infection in vaccinated health care workers. post
TWiVsters review off-season epidemics of respiratory syncytial virus in Australia after easing of COVID-19 restrictions, and impaired innate immune responses in upper respiratory tract cells from patients with severe COVID-19. post
In this special episode, Daniel Griffin answers listener questions on COVID-19 vaccines, vaccine misinformation, long COVID, masking and distancing, school safety, and much more. post
Immune explore the observation that bat cells display dampened STING-dependent interferon activation, suggesting why bats might have a unique capacity to harbor many viruses. 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
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
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
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
