Lipid membranes, which form the outer layer of cells, can be engineered to influence cellular functions. For example, ...

Encoded within this DNA are the directions for traits as diverse as the color of a person's eyes, the scent of a rose, and the way in which bacteria infect a lung cell. DNA is found in nearly all ...

DNA repair: A look inside the cell's 'repair café' Date: November 21, 2024 Source: Hubrecht Institute Summary: New research sheds light on how cells repair damaged DNA. For the first time, the ...

But those cells have a formidable challenge. The average dividing cell must copy—perfectly—3.2 billion base pairs of DNA, about once every 24 hours. The cell’s replication machinery does an ...

The transfer of this principle to artificial cells is a challenge in synthetic biology. Advances in DNA nanotechnology now offer promising solutions. They allow the creation of novel transport ...

Their engineered cells can insert distinctive bits of genetic material into their DNA. As the cells divide, those genetic bits turn into distinctive bar codes. The technology is also allowing ...

Using DNA and proteins, scientists have created new synthetic cells that act like living cells. Blurring the line between artificial and living materials, these cells can be reprogrammed to ...

First, they gave groups of five mice engrafted with leukemia cells each one of two types of PTEs targeting different antigens or a control solution. Artificial DNA molecule offers powerful new ...
