Taiwanese researchers discover new form of cell division that does not copy DNA

  • Researchers at Academia Sinica, Taiwan’s national academic institution, identified a new form of cell division that does not replicate DNA.
  • Since the 1870s, only two forms of cell division — mitosis and meiosis — have been known to science.
  • Using zebrafish larvae, the team observed how some skin cells proliferate by splitting instead of duplicating their DNA.
  • The process, known as asynthetic fission, occurs so quickly that “mistakes” have occurred, such as an uneven separation of DNA between new cells.
  • Despite such mistakes, the zebrafish naturally eliminated the erroneous cells and replaced them with normal ones weeks later.
  • Dr. Chen-Hui Chen, who led the research team, is focused on the zebrafish’s regeneration of complex tissues and how the process can be translated for humans.

Researchers at Academia Sinica, Taiwan’s national academic institution, have identified a new form of cell division that does not involve the replication of DNA.

The discovery, published in the journal Nature on April 27, provides new insight on one of the most elementary processes that allow for life to thrive on Earth.

Japanese Man Saves Dying Forest in The Philippines By Eating Thousands of Mangoes in the 1970s

Almost half a century ago, a Japanese horticulturist initiated an effort to rebuild a deforested mountain in the Philippines.

It was in the early 1970s and Osamu Nakagaki was only 25 when he invited his friends and volunteers to eat as many mangoes as they could so he could gather the seeds he needed for planting in San Fernando City in La Union.
