Enlarge (credit: Katja Schulz) A number of bacteria that infect insects have a simple and brutal way of increasing their transmission: they kill off all the male progeny of the females that they infect. There’s actually some evolutionary logic to this. The bacteria can get transmitted to the eggs of the females they infect but […]
U.S. Centers for Disease Control reports a rise in bacteria with unusual resistance to antibiotics of last resort across the country last year.
Swiss and American researchers counted the microbes swimming inside the toys and say the murky liquid released when ducks were squeezed contained “potentially pathogenic bacteria” in four out of the five toys studied.
Loblaw Companies Ltd. is recalling certain pre-packaged Cooked Shrimp due to the potential presence of raw shrimp, which may contain harmful bacteria.

In a wee survey, Loyola University Chicago researchers found the sac-like organ brimming with never-before-seen viruses that can kill and manipulate bacteria. Their findings, published this week in the Journal of Bacteriology, offer a […]

(credit: Getty | Hulton Archive) An ancient bacterium known for devastating and disfiguring its victims has turned to frantically ravaging its own genome to maintain its killer status, according to a new study. Arran Reeve, suffering from leprosy, […]

By 1576, the population, which had been more than 20 million before the Spanish arrived, had crashed to two million. One brutal outbreak in 1545 […]
Enlarge Life performs many astonishing feats of chemistry, building complex molecules that can take us years to figure out how to synthesize. And the thermodynamics of these reactions are often fascinating—in many cases, life lives on the edge, at risk of seeing critical reactions bog down and run in reverse. Now, some researchers have figured […]
In a new study published today in Science Advances, researchers present a 3D-printable ink that contains bacteria and they say that depending on what species of bacteria it holds, the ink stands to have a number of useful applications. “Printing using bacteria-containing hydrogels has enormous potential, as there is such a wide range of useful […]
