Bacteria - you can live without 'em, but it won't do you any good!

The finding challenges the conventional wisdom that even harmless bacteria – and the immune response they provoke – suck up the energy of the host organism and hasten its death.

Multifunctional nanoparticle platforms for targeting and imaging cancer cells

There has been much recent interest in how nanotechnology will impact the field of medicine. Unfortunately, a number of promising nanostructured systems have turned out to be extremely toxic to humans, thus precluding their use in clinical applications and dashing hopes of an early success for the interdisciplinary field of nanobiotechnology.

Novel two-step mechanism ensures that all cilia beat in unison

Cilia, tiny hair-like structures that propel mucus out of airways, have to agree on the direction of the fluid flow to get things moving. Researchers at the Salk Institute for Biological Studies discovered a novel two-step mechanism that ensures that all cilia beat in unison.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.
