Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...n their study, the researchers inserted fine tubes into the spiracles of a moth to measure not only how much carbon dioxide the moth released but also the concentration of oxygen in its trachea, the series of tubes that carry air directly to cells for gas exchange. Using a respirometer (an instrument for ...

NIAID Initiates Trial of Experimental Avian Flu Vaccine

...blic health experts fear that the virus may evolve into one that is more easily transmitted between people. If this were to happen, a worldwide pandemic could follow. Influenza pandemics are global outbreaks that emerge infrequently and unpredictably and involve strains of virus to which humans have litt...

Scientists document complex genomic events leading to the birth of new genes

...eting them from the gene pool or by degrading them into non-functional pseudogenes. This is because fully functional duplicated genes, in combination with the corresponding parent gene, produce abnormally abundant quantities of transcripts. This overexpression often alters the fragile molecular balance of...
