Protein aggregates are associated with the development of diseases like Alzheimer's and Parkinson's. These are found more ...

For cells to function properly, they must produce the right amount of each protein. It is a delicate balance: Both too little ...

Cells carry their own growth switches. When enough nutrients-amino acids in particular-are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have now ...

Cells are like metropolises, home to millions of molecular residents. If one were to stand atop a high-rise, trying to ...

The planet is getting hotter, and life will need to adapt to rising temperatures to survive. One way cells adapt to changing ...

A nerve cell resembles a vast tree with branches that communicate with thousands of other cells. To function, it depends on a ...

Origami masters turn simple sheets of paper into ornate sculptures. In the origami of life, our cells must fold proteins into specific three-dimensional shapes before they can carry out their ...

Scientists have mapped how a brain protein spreads Alzheimer’s between neurons. This discovery could lead to new ways to halt ...

Before seedlings can photosynthesize, they depend on fatty acids—and on peroxisomes to process them. Researchers discovered that the protein PEX11 not only helps these structures divide but also ...

Structures called desmosomes connect cells to each other and transfer mechanical stress. They are especially important in tissues under continual mechanical stress, such as heart muscle (pictured).

Protein production in insect cells or in whole insects could move past the trade-off long associated with conventional ...
