Researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.

Neuroscientists can now capture millisecond electrical changes in neurons in the cortex of an alert mouse, allowing tracing of neural signals, including subthreshold events, in the brain. The new technique combines all-optical scanning with two-photon fluorescence imaging to produce a 2D rasterized picture every 1,000-3,000 milliseconds. That and another technique that allows 3D imaging of […]

A new study has provided the most comprehensive analysis of human genetic diversity to date, after the sequencing of 929 human genomes. The study uncovers a large amount of previously undescribed genetic variation and provides new insights into our evolutionary past, highlighting the complexity of the process through which our ancestors diversified, migrated and mixed […]

In the 1960s, public health officials led the US and worldwide efforts that resulted in smallpox becoming the first human disease ever eradicated from the face of the earth. Researchers say appropriate concerns and not fear should play a major role in the emerging coronavirus pandemic, and public health efforts should focus on public health […]
