How diarrhea pathogens switch into attack mode at body temperature

Many bacterial pathogens excrete toxins as soon as they have entered the host in order to suppress its immune response. Researchers at Ruhr-Universität Bochum (RUB) have analyzed what happens on the molecular level when ...

Cellular clock regulating human spine development

More than 20 years ago, the lab of developmental biologist Olivier Pourquié discovered a sort of cellular clock in chicken embryos where each "tick" stimulates the formation of a structure called a somite that ultimately ...

Neuroscience

A molecular map of the brain's decision-making area

Researchers at Karolinska Institutet have come one step closer toward understanding how the part of our brain that is central for decision-making and the development of addiction is organized on a molecular level. In mouse ...

Cardiology

An atomic view of the trigger for the heartbeat

Atomic-level studies of the architecture of tiny sodium channel proteins, critical to generating electrical signals that start off each beat of the heart, are imparting striking details about their function, malfunctions, ...

Genetics

Form of severe malnutrition linked to DNA modification

A group led by researchers at Baylor College of Medicine has identified significant differences at the epigenetic level—the chemical tags in DNA that help regulate gene expression—between two clinically distinct forms ...
