Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
To take full advantage of recent increased financial commitments from some governments, international agencies, and philanthropies, accurate and up-to-date mapping of neglected tropical diseases (NTDs) needs to be implemented to help improve the precision of decision-making in NTD control and el...

Current methods of diagnosing an infectious disease can take days to weeks. Now a Cambridge, MA-based startup called Pathogenica is developing a way to do it within a day--by reading the DNA sequence of pathogens.
Pathogenica is developing diagnostic tests designed to detect harmful microorga... Read More
In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the g... Read More
Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.
Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimatel... Read More
It is widely accepted that the shift in case-fatality rate between waves during the 1918 influenza pandemic was due to a genetic change in the virus. In animal models, the infectious dose of influenza A virus was associated to the severity of disease which lead us to propose a new ... Read More
