Researchers show how bacteria transmit motion from an inner motor to an outer tail through a flexible joint in the flagellum known as the hook. This finding could help in the fight against deadly bacterial infections. By better understanding how bacteria move, researchers may be able to improve disease prevention strategies.
Read moreFor the first time ever, investigators have identified a washing machine as a reservoir of multidrug-resistant pathogens. The pathogens, a single clone of Klebsiella oxytoca, were transmitted repeatedly to newborns in a neonatal intensive care unit at a children's hospital. The transmission was stopped only when the washing machine was removed from the hospital.

The extreme environment of Mono Lake was thought to only house two species of animals — until now.
Fossil animal droppings, charcoal from ancient fires and bone fragments litter the ground of one of the world's most important human evolution sites, new research reveals. A team of scientists have used modern geoarchaeological techniques to unearth new details of day-to-day life in the famous Denisova Cave complex in Siberia's Altai Mountains.
Read moreFor the first time, scientists were able to observe bacteria forming pearl chains that protrude from the cell surface. These pearl chains serve to better absorb and store substances from the environment.
Read moreAs some of the most savvy and sophisticated predators out there, bats eavesdrop on their prey and even on other bats to collect a wide variety of information as they hunt.
Read moreWhile viruses are typically known for their pathogenic properties, new research findings now also demonstrate a positive influence of bacteriophages on the interaction of host organisms with bacteria. A new study sheds new light on the symbiosis between multicellular organisms and their microbial communities, which may be regulated by bacteriophages in a tripartite relationship.
Read moreThe memory of the immune system is able to distinguish a foreign protein with which the organism has already come into contact from another and to react with a corresponding antibody. Researchers have now discovered in flour beetles that the immune system's ability to specifically fend off pathogens can adapt in the course of evolution.
Read moreThe low FODMAP diet, a diet low in carbohydrates that trigger digestive symptoms like bloating and stomach pain, is a useful treatment in children and adolescents with gastrointestinal problems, new research confirms.
Read moreResearchers have developed an electronic chip that can perform high-sensitivity intracellular recording from thousands of connected neurons simultaneously. This breakthrough allowed them to map synaptic connectivity at an unprecedented level, identifying hundreds of synaptic connections.
