Fluid Dynamics of Stentors Offers New Insight Into Evolution of Multicellular Life

Life emerged on Earth some 3.8 billion years ago. The "primordial soup theory" proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously formed organic molecules.

Gamma-Actin's Influence on Cell Rigidity and Junctional Proteins

Epithelial cells defend human skin and mucous membranes. Specialized structures known as “junctions” enable this “barrier” tissue to carry out its role. They control interactions between cells and maintain cell cohesion.

Engineers Turn the Body’s Goo Into New Glue

Within the animal kingdom, mussels are masters of underwater adhesion. The marine mollusks cluster atop rocks and along the bottoms of ships, and hold fast against the ocean’s waves thanks to a gluey plaque they secrete through their foot.

Male Flies Evolve Sharper Vision to Outwit Female Mating Tricks

With bloated bellies and hairy legs, female flies try to look bigger to get food from courting mates. But male flies, in turn, have sharpened their eyesight to call their bluff.

Scientists Uncover Key Plant Metabolite to Block Biofilm Development

If your teeth have ever felt fuzzy after skipping a brushing, you've encountered biofilm-a slimy bacterial layer that clings to surfaces. In medical settings, biofilms make infections harder to treat when they form protective shields for bacteria on devices like catheters and implants.

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.

New Discovery Redefines the Shape of Axons in Mammalian Brain Cells

Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have assumed for more than a century.

The Role of Neural Crest Stem Cells in Cellular Reprogramming

Researchers at the University of Toronto have identified that neural crest stem cells, a group of cells located in the skin and other parts of the body, are the origin of reprogrammed neurons previously discovered by other scientists.

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.
