Axolotls regenerate functional thymus after complete removal

The axolotl, a type of salamander that stays in the tadpole form throughout its life, is a master of regeneration. Axolotls have been observed to regrow several body parts, including limbs, eyes, and even parts of their brains.

Thousands of oysters are being re-introduced to Dublin Bay as nature's super water cleaners

For over 200 years, native oysters (Ostrea edulis) have been absent in Dublin Bay. Once abundant along the Irish coast, they thrived in the sheltered estuaries and tidal flats that shaped the city's maritime life.

Researchers discover enlarged areas of the spinal cord in fish, previously found only in four-limbed vertebrates

Four-limbed vertebrates, known as tetrapods, have two enlarged areas in their spinal cords. The two enlargements have a correlation with the forelimbs and hind limbs, respectively. These enlargements are thought to be caused ...
