A Tale of Three Biofilm Cities on Aeration Diffusers

Fine pore diffusers are devices that pump air into wastewater in order to stimulate biodegradation of organic matter. Aeration of wastewater incur a large maintenance cost due to the buildup of biofilm, which is one of the biggest costs to the operation of sewage treatment plants. The biofilms ... Read More

A Tiny Zika Laboratory

So far in this series I’ve written a good deal about our work on Zika virus, but I have said little about the people who are doing the science.

My lab at Columbia University Medical Center is very small, consisting of three people—Amy Rosenfeld, Audrey Warren, and me. Let me tell you about ... Read More

Staining of Unknown Fungal sp.

While isolating organisms growing in a water system a dark Fungal growth was noted. I love isolating fungi and staining them in a manner that produces contrast among the hyphae. This fungi is yet to be identified but through the lense of a microscope it looks comparable to a tree in the fall a... Read More

Mount Sinai researchers track HIV in real time as it infects and spreads in living tissue

By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles. These interactions allow HIV to spread ... Read More

Small RNAs regulate Bacteroides nutrient use

Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
