We are not only a little Neanderthals, but also a little Denisovans

Melanesians inhabiting the islands to the northeast of Australia received 4-6% of their genes from Denisovans. If we consider that the Neanderthals also left a trace in the genomes of modern humans, the total contribution of the "cousins" will be about 8%.

Macroporous ferrogel squeezes medicines into a sore spot

The new material, called macroporous ferrogel, can be compressed up to 70 percent by a magnetic field. Reversible metered compression removes drugs or cells and proteins embedded in the gel from the gel.
