How the cell protects itself

The cell contains transcripts of genetic material, which migrate from the cell nucleus to another part of the cell. This movement protects the genetic transcripts from the recruitment of "spliceosomes." If this protection ...

An effective sweeper closes DNA replication cycling

DNA replication is essential for living organisms to faithfully deliver genetic information from parental cells to daughter cells. Many proteins are assembled on the parental DNA to work as replication machineries. Among ...

A new mechanism for accessing damaged DNA

UV light damages the DNA of skin cells, which can lead to skin cancer. But this process is counteracted by DNA repair machinery, acting as a molecular sunscreen. It has been unclear, however, how repair proteins work on DNA ...

Study of Arctic fishes reveals the birth of a gene—from 'junk'

Though separated by a world of ocean, and unrelated to each other, two fish groups—one in the Arctic, the other in the Antarctic—share a surprising survival strategy: They both have evolved the ability to produce the ...

New hydraulic actuator will make robots tougher

Researchers at the Tokyo Institute of Technology (Tokyo Tech) have developed a hydraulic actuator that will allow tough robots to operate in disaster sites and other harsh environments. The Tokyo Tech Venture H-MUSCLE Corporation ...
