Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

In a study that may guide drug design, researchers find organelles encounter varying levels of resistance, depending on their size and speed, as they move through a cell's cytoplasm. Under a ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is densely packed with biomolecules like proteins and nucleic acids. How is ...

UC Davis researchers tracked the movement of fluorescent particles inside the cells of microscopic worms, providing novel insights into cellular crowding in a multicellular animal. They found that the ...

Back in 2018, the lab of Christine Mayr, MD, PhD, at Memorial Sloan Kettering Cancer Center (MSK) introduced the world to a key cellular component that had been hiding in plain sight. Now the lab is ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

Put a banana in a blender, and you don’t expect to get it back. But blend up a bunch of living cells and new research suggests that you maybe should. If simply left alone, the liquid innards of a cell ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

CAMBRIDGE, Mass. -- Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, ...
