How biological aging clocks tick

Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a program. Scientists have now discovered that aging clocks actually measure the increase in stochastic changes in cells.

Fluidic systems resembling blood vascular tissues: Artificial blood vessels and biomedicine

Nature has consistently inspired engineering applications. Recently, a group of researchers drew new inspirations from the vascular network and developed a new type of fluidic system named VasFluidics.

An epigenome editing toolkit to dissect the mechanisms of gene regulation

A recent study led to the development of a powerful epigenetic editing technology. The system unlocks the ability to precisely program chromatin modifications at any specific position in the genome, to understand their causal role in transcription regulation. This innovative approach will help to investigate the role of chromatin modifications in many biological processes, and to program desired gene activity responses, which may prove useful in disease settings.

Whooping cough cases up again as five babies die

There were 1,300 cases of the bacterial infection in March, after just over 900 in February in England....
