New Study Reveals DNA’s Role in Stabilizing Cellular Structures

In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium.

New Study Links Ancient Human Remains from Zlatý kůň and Ranis in Genetic Findings

After modern humans left Africa, they met and interbred with Neandertals, resulting in around two to three percent Neandertal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pioneers in Europe and the timing of the Neandertal admixture with non-Africans.

Unraveling the Spatial Complexity of Gene Expression with Seq-Scope

A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.

New Microscope Peels Back Layers of Cellular Mystery

What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers from the Universities of Göttingen and Oxford, in collaboration with the University Medical Center Göttingen (UMG), have succeeded in developing a microscope with resolutions better than five nanometers (five billionths of a meter). This is roughly equivalent to the width of a hair split into 10,000 strands. Their new method was published in Nature Photonics.
