Here’s what a fascinating case of twin girls born conjoined at the head tells us about the brain—and the soul—says neurosurgeon Dr. Michael Egnor. “They have what's called a thalamic bridge, which is a bridge of brain tissue that connects the deepest parts of their brains. So their brains connect, and they can do some remarkable things. They can see at least partially through each other's eyes. They can feel, to some extent, each other's skin. There's a video of their mother sitting with them on

Thoracopagus twins are the most common form of conjoined twinning, joined at the chest and often sharing vital organs such as the heart and liver. Because their anatomy is so closely intertwined, each case offers rare insight into human development. Conjoined twinning happens very early in pregnancy, around 13–15 days after fertilization, when the developing embryo begins to form the body plan. The leading theory is that the embryo partially splits but does not fully separate, resulting in two i

Cyclopia plicata or Needle leaf tea is an endangered Honeybush with a localised distribution in the Kammanassie and far western Kouga mountains. This high-yielding reseeder plant, which once produced abundant harvest in the wild, is reduced to only a few known populations. The species is red-listed and harvesting is prohibited. The story reminds us of the need for sustainable use of our precious wild resources. We are encouraged to see new growth of Cyclopia plicata emerging in abundance after t
