Ball-and-chain inactivation of ion channels visualized by cryo-electron microscopy

Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function. These channels use a ''ball-and-chain'' mechanism to help regulate their ion flow, according to a new study.

Tomosynthesis outperforms digital mammography in five-year study

A new study has found that the advantages of digital breast tomosynthesis (DBT) over digital mammography (DM), including increased cancer detection and fewer false positive findings, are maintained over multiple years and rounds of screening. In addition, research showed that DBT screening helped detect a higher proportion of poor prognosis cancers than DM.

Researchers help restore hormonal balance disrupted in metabolic diseases

Many health problems in the developed world stem from the disruption of a delicate metabolic balance between glucose production and energy utilization in the liver. Now scientists report that they have discovered the molecular mechanisms that trigger metabolic imbalance between these two distinct but linked processes, a finding with implications for the treatment of diabetes and non-alcoholic fatty liver disease.
