A plant that thrives in nickel-rich dirt has been discovered in the Philippines. Rinorea niccolifera can absorb large amounts of nickel through its leaves.


Regrown bone in monkeys using pluripotent stem cells

It could be possible to grow new bone in humans using induced pluripotent stem cells, as seen in an experiment with rhesus macaques. Skin cells from monkeys were transformed into iPSCs, which were transplanted into the monkeys using a bone scaffold. There was no sign of tumor growth after injecting differentiated bone precursor cells, but a type of tumor known as a teratoma formed when undifferentiated stem cells were injected, although the lesions grew 20 times slower than they do in mice.

Melting of West Antarctic ice sheet can’t be stopped

The ice sheet in West Antarctica is breaking up and its continued melting may be unavoidable, leading to a slow rise of 10 feet, or about 3 meters, in the sea level over the next centuries, according to two separate and independent studies.
