[ad_1] Credit: Jennifer Cook-Chrysos / Whitehead Institute MicroRNAs are short sequences of RNA that maintain tight control over which genes are expressed and when. They do this by regulating which messenger RNA (mRNA) transcripts – the single-stranded templates for proteins – are actually read by the cell. But what controls …

[ad_1] DALLAS – November 12, 2020 – Researchers at UT Southwestern have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amount of protein in cells. The results, reported online today in Science, not only sheds light on the inner workings of cells, but …

[ad_1] An artistic interpretation of the creation of two cell atlases that trace gene expression and chromatin accessibility during the development of human cell types and tissues. The atlases are reported in the November 12 edition of Science. They were developed by the Brotman Baty Institute for Precision Medicine and …

[ad_1] This image shows the glow of a kilonova caused by the merger of two neutron stars. The kilonova, whose maximum brightness reaches up to 10,000 times that of a classical nova, appears as a bright spot (indicated by the arrow) in the upper left of the host galaxy. The …

[ad_1] Using a stripped down climate model, Randers and colleague Ulrich Goluke predicted changes up to the year 2500 in two scenarios: the instantaneous cessation of emissions and the gradual reduction to zero of global warming gases by 2100. Global warming will disrupt food supplies, slow global economic growth and …
