How 'Iron Man' bacteria could help protect the environment

When Michigan State University's Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not "environmentally relevant."

Discovery of a genetic sex marker in sturgeon

Scientists have discovered a molecular marker for sex determination in sturgeon within the international project STURGEoNOMICS, led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). This discovery ...

Flaws emerge in modeling human genetic diseases in animals

My lab, based at the University of Southern California Keck School of Medicine, uses zebrafish to model human birth defects affecting the face. When I tell people this, they are often skeptical that fish biology has any relevance ...

How malaria parasites withstand a fever's heat

Even when a person suffering from malaria is burning up with fever and too sick to function, the tiny blood-eating parasites lurking inside them continue to flourish, relentlessly growing and multiplying as they gobble up ...

A new strategy of cell entry for some types of parvoviruses

Researchers at the Institut national de la recherche scientifique (INRS), in collaboration with American scientists, have discovered a new parvovirus strategy for reaching the cell nucleus, where they reproduce. The results ...

RNA information transfer could be used in repairing DNA

Genomes are routinely subjected to DNA damage. But most cells have DNA repair systems that enforce genome stability and, ideally, prevent diseases like cancer. The trouble gets serious when these systems break down. When ...
