UNIVERSITY OF ROCHESTER, KIHONG LIMNeutrophils that storm the influenza-infected mouse throat leave a trail of chemicals that lead T cells to the site, researchers from the University of Rochester in New York showed this week (September 3) in Science.
“The paper goes very far, using an infection model to not only describe a phenomenon, but to clarify the molecular cascade of events in impressive detail,” said Michael Sixt of the Institute of Science and Technology Austria in Klosterneuburg who penned an accompanying commentary but was not involved in the work.
“This study suggests that T cells also don’t really know where to go without the help of key innate immune system cells like neutrophils,” said immunologist and evolutionary ecologist Andrea Graham of Princeton University who also did not participate in the research.
NASAOver the long term, elevated carbon dioxide (CO2) levels can irreversibly increase the oceanic cyanobacterium Trichodesmium erythraeum’s ability to fix nitrogen, according to a study published in Nature Communications this week (September 1). Scientists from the University of Southern California and the Woods Hole Oceanographic Institute in Massachusetts used experimental evolution to track the adaptation of T. erythraeum to varying environmental conditions for more than four years.
“It’s an elegant study because they’re really ...
