A novel type of imaging dubbed DNA microscopy that can see inside cells at the genomic level has been invented by Howard Hughes Medical Institute (HHMI) investigators. Rather than relying on light, or any kind of optics at all, the method uses DNA “bar codes” to help pinpoint molecules’ relative positions within a sample. With… Read more

A new imaging technology could allow scientists to look inside cells and watch dozens of different molecules in action at once, by labeling them with short strands of  barcoded DNA that blink on and off with their own unique rhythm. When attached to cells or other objects and observed for enough time, these barcodes could… Read more

A memristive element made from nanowires that functions in much the same way as a biological nerve cell has been produced by scientists from Forschungszentrum Jülich along with colleagues from Aachen and Turin. The component is able to save and process information, as well as receive numerous signals in parallel. The resistive switching cell made… Read more

High levels of human-made CO2 causes ocean acidification that is rapidly dissolving the seafloor, a new study warns. Normally the deep sea bottom is a chalky white. It’s composed, to a large extent, of the mineral calcite (CaCO3) formed from the skeletons and shells of many planktonic organisms and corals. The seafloor plays a crucial… Read more

At the cutting edge of modern science, DNA sequencing promises to transform many aspects of human life. It’s already playing a significant role in law enforcement, as well as medical and historical research. But there’s a growing inequality in its impacts and in the chances of your genetic data being recorded – whether that’s by… Read more
