By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

Advances in organ and computer models are raising the prospect that some animal experiments could be eliminated. But there ...

According to the data considered by its authors—a team from the University of Sussex (UK) and Lund University ...

Advanced 3D reconstructions of the comb jelly’s aboral organ reveal a sensory system far more complex than scientists expected. The organ contains a wide variety of specialized cells and is closely ...

A UCSF team finds a liver protein, released with exercise, that improves memory in aging and Alzheimer’s disease by repairing the brain’s blood vessels. It's the missing link between exercise and ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...

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 ...

A 3D rendering showing the internal structure of an animal cell, with several round or wavy structures inside a border. It turns out that the redox state of a cell, such as the animal cell shown, is ...

Here’s what you’ll learn when you read this story: With more than 100,000 people in need of an organ transplant in the U.S. alone, scientists have turned toward perfecting human-animal chimeras as a ...

An animal cell is a fascinating topic within the science curriculum as it provides an opportunity for students to explore the building blocks of life. Creating an animal cell model is an excellent way ...

An international team of researchers has created the most detailed model yet of how cells regulate traffic through the nuclear pore complex—the gateway between a cell’s nucleus and its cytoplasm. The ...

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 ...
