Undersea warfare: Viruses hijack deep-sea bacteria at hydrothermal vents
Washington DC (SPX) May 02, 2014
More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells. Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur reserves, then use the unleashed energ ... read more
