The Vertical Farm
By Vincent Racaniello
I've been hearing about the vertical farm concept from Dickson Despommier for years - as a faculty colleague of his here at Columbia University Medical Center, and more recently as co-host of TWiV and TWiP. I could not help but be enthusiastic as the idea grew from a seed, to ...
Prokaryotes considered
By Vincent Racaniello
As a college biology major during the 1970s I was taught that cells in which the genetic material is separated from the cytoplasm by a nuclear membrane - such as those of animals, fungi, plants, and protists - are called eukaryotes. In contrast, the DNA of bacteria is not bounded ...

Antibodies neutralize viral infectivity inside cells
By Vincent Racaniello
Antibodies are an important component of the host defense against viral infection. These molecules, produced 7-14 days after infection, neutralize viral infectivity, thereby limiting the spread of infection. Antibodies are thought to neutralize viral infectivity in several ways: by forming noninfectious aggregates that cannot enter cells, or by blocking virion ...
