Venomous Or Poisonous, Crayfish Clones, Immune System Cancer Injection. Feb 9, 2018, Part 2

Do you know the difference between a poisonous creature and a venomous one? One distinction is that poisons are often ingested or absorbed by the skin, while venoms have to be injected through a wound. Mandë Holford tells us more about her research studying these dangerous creatures.

25 years ago, all-female crayfish species originated from a hobbyist tank in Germany. In the wild, the crustacean developed a mutation that allowed it to pick up a third set of chromosomes and reproduce clonally. Since then, the cloning crayfish have proliferated—invading waters all around the world. What do the neurons of this clonal creature tell us about its ability to adapt to different environments?

It's known that the immune system can fight cancer—and there have been heavy investments in the search for a drug that will boost our own body’s ability to combat cancer. Now, researchers at Stanford University may have discovered a treatment that’s not only quick, but also doesn’t send the body’s immune system into overdrive.
