A new paper has been published in Nature Communications. Entitled “Disentangling top-down drivers of mortality underlying diel population dynamics of Prochlorococcus in the North Pacific Subtropical Gyre,” the study provides insights into the lifecycle of photosynthetic microbes that drive the base of marine food webs. As shared by the University of Maryland’s Biology Department, “the findings […]
Look for our new paper out in Science, titled “Rapid bacteria-phage coevolution drives the emergence of multiscale networks.” This work is was done in collaboration with Justin Meyer and his group of researchers from the University of California in San Diego. The editor’s summary of this article reads: Real communities are characterized by complex interaction […]
localcovid19now: a new, updated software to process and map local Covid-19 case data
There has been a low uptake of the new (available since early September ’22) bivalent booster COVID-19 vaccine in the USA (~15% of the population as of 10th January 2023). In this work, we set to ask the reasons why people are, or are not, electing to take the bivalent booster. One key finding from analyzing survey data is that many people did not know about the new bivalent booster, or did not know they were eligible — suggesting more public health communication is necessary to promote uptake of the new vaccines. You can read more about it here.
In early 2020, members of the Weitz Group were part of a dedicated team of Georgia Tech researchers, engineers, campus leaders, and staff members working to establish Georgia Tech’s surveillance testing program. The goal of the program was to use testing to reduce the spread of Covid-19 and increase campus safety. A collaborative paper on […]
Look for our new paper out in Ecology Letters, titled “Leapfrog dynamics in phage-bacteria coevolution revealed by joint analysis of cross-infection phenotypes and whole genome sequencing.” This work is was done in collaboration with researchers from the University of California in San Diego as well as former group members Shengyun Peng and Chun Yin Leung.
In collaboration with 13 other institutions, new work investigating changes in microbial metabolism with the diel cycle has been published in Nature Ecology and Evolution. Led by Prof. Weitz, group members Daniel Muratore, who served as one of three co-first authors, Stephen Beckett, Ph.D., and Rogelio Rodriguez-Gonzalez contributed to this work. Read more about the paper […]
In collaboration with Benjamin Lopman‘s group at Emory University, our recent work entitled “A framework for monitoring population immunity to SARS-CoV-2” was published in Annals of Epidemiology. The proposed framework suggests combining records of vaccinations and natural infections to assess immunity to Covid-19 at the population level. A dashboard was also created to track estimates […]
In collaboration with researchers from Georgia Tech, Brown University, and the Technical University of Denmark, Prof Weitz has published a new paper entitled “Heterogeneity in susceptibility dictates the order of epidemic models” in the Journal of Theoretical Biology. This work examines the complicated relationship between susceptibility to infection and infection spread in epidemics, highlighting the need […]
A paper entitled “Disease-dependent interaction policies to support health and economic outcomes during the Covid-19 epidemic” is now available in iScience. This study examines the effectiveness of modulating the rate of interaction between individuals based on the epidemic state in mitigating Covid-19. Results demonstrate that using population-wide PCR testing for Covid-19 alongside immune status “can reduce […]
