Mapping the transcriptional landscape of algal resistance to viral infection reveals a core expression program Algal blooms and their demise by viruses drive global-scale ecological processes in the ocean. These blooms form the foundation of marine food webs, regulate microbial communities, and shape biogeoc...

📣 We are excited to share our latest paper, led by @taliashaler.bsky.social! We explore the transcriptional basis of #microalgae resistance to #viral_infection and identified a core group of resistance-related genes. >>

Cyanophage Infections in a Sponge Intracellular Cyanobacterial Symbiont Intracellular cyanobacterial symbionts of sponges are shown to be susceptible to cyanophages, challenging assumptions about their isolation from viral exposure. The study reveals novel phage–host int...

Our paper on cyanophages of marine sponge symbionts is finally out. It is the outcome of a great collaboration with Laura Steindler's lab and was led by Tzipora Perez.

Expression level of anti-phage defence systems controls a trade-off between protection range and autoimmunity - Nature Microbiology The authors examine several defense systems and find that increased expression enhances their protection range, albeit at a cost of autoimmunity.

Virus-mediated recycling of chemoautotrophic biomass Aquatic environments absorb ~2.5 gigatonnes of atmospheric carbon each year, more than the carbon stored in the atmosphere, soils, and all biomass combined. Primary producers transform this dissolved ...

Lab's first preprint! #newPI

We show that viruses are active agents that recycle carbon fixed by productive chemoautotrophs, shaping our understanding of carbon cycling in redox-active ecosystems.

Can you add me? Thanks

This paper has been a long time coming: We looked at the genomes of historical bacterial samples over a century to look for trends of antibiotic resistance genes, finding multiple instances of them in infections before the age of antibiotics, but an increase in both frequency and mobility after

Very exciting 😀

את לגמרי צודקת ברמה העקרונית. אבל יש שם ממש קהילה סביב בית הספר, וגם סטודנטים לרפואה תמיד היו שם ובטוח אין להם כסף לשכור את הדירות החדשות שבונים שם.. עניין הרכבת כן מרגיש רלוונטי.
