Male-only gene trick could leave invasive fish species floundering

A genetic modification that creates male-only populations could give us a new weapon against invasive fish such as carp that plague our waterways. “Daughterless technology”, which works by removing females…

Australia should enlist dingoes to control invasive species

Introduced species pose one of the greatest threats to Australia’s fauna and flora, but expensive efforts to control them aren’t working. Instead of spending millions of dollars on culling, giving dingoes…
