Genetic research reveals Neanderthals could tolerate smoke, plant toxins

Comparison of Modern Human and Neanderthal skulls from the Cleveland Museum of Natural History. Credit: DrMikeBaxter/Wikipedia The idea that modern humans displaced Neanderthals because they were better protected against toxins from smoke is now under fire. An earlier study that put forward this suggestion has now been refuted by genetic research by scientists from Leiden […]

Tube-dwelling anemone toxins have pharmacological potential, mapping study shows

Analysis identified 525 genes encoding proteins that act on the nervous system, cardiovascular system and cell walls. One of the molecules proved effective against cancer cells in preliminary test results.
