Researchers engineer bacteria that can detect tumor DNA

Pushing into a new chapter of technologically advanced biological sensors, scientists from the University of California San Diego and their colleagues in Australia have engineered bacteria that can detect the presence of ...

Removal of a gene could render lethal poxviruses harmless

The removal of one gene renders poxviruses—a lethal family of viral infections that are known to spread from animals to humans—harmless, a new study in the journal Science Advances reports.

Tissue structure delays cancer development

Cancer growth normally follows a lengthy period of development. Over the course of time, genetic mutations often accumulate in cells, leading first to pre-cancerous conditions and ultimately to tumour growth. Using a mathematical ...

Different paths to drug resistance in Leishmania

Two remarkable discoveries were today revealed by researchers into genome analysis of Leishmania parasites. These results uncovered a surprising level of variation at the genome structure level.
