Questions about how E. coli evolves; spermatids in a dish; fighting bacteria with virus-like molecule; what drives metastasis; antibodies fight Ebola in monkeys
Researchers identify a molecule that may have been key to the surprisingly common transition from single-celled ancestors to today’s complex, multicellular organisms.
Chilly mice develop more tumors; gut bacteria aid cancer treatment; two Y chromosome genes sufficient for assisted reproduction; HIV’s “invisibility cloak”
Researchers are working to understand how often-colorless biological nanostructures give rise to some of the most spectacular technicolor displays in nature.
The widespread bacteria known to manipulate host reproductive output can do so by ramping up stem cell division and consequent egg production in Drosophila.
