Researchers at the University of Toronto's Institute of Biomedical Engineering have developed a new method to mature lab-grown heart cells, so they more closely resemble adult human heart tissue. By ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...

A startup out of Utah, Paterna Biosciences, says it has successfully grown functional human sperm in a lab and used the sperm to make visibly healthy-looking embryos. The technique could eventually ...

Sustainability in the cell culture lab is no longer optional, but knowing what truly makes an impact can be challenging. With increasing claims and product labels in the market, it can be difficult to ...

Paterna Biosciences said it has mastered the molecular signals that teach stem cells how to mature into sperm for a promising new fertility treatment. Reading time 3 minutes More than one in eight ...

This is the kind of clip that makes your blood pressure rise almost instantly. A guest walks onto a podcast, declares evolution “a religion,” and says it has nothing to do with science like that ...

Plant scientist Dario Leister and his team are investigating how cyanobacteria adapt to rapidly changing light intensities.

When a parasite invades a cell, the cell’s mitochondria react by shedding their outer layers to form brand-new cellular compartments — or organelles — that digest molecular trash. Cells are swapping ...
