Scientists in the UK and Germany have viewed individual metal atoms making and breaking bonds. They used carbon nanotubes as a scaffold to hold the atoms in place. This is with individual rhenium atoms. You can see the distance between the atoms grow and shrink depending on the environment. It looks like this type of microscopy will become important in chemistry.
The Northern White Rhinos are almost extinct. There are two still alive, and both are females. This does not bode well for future cute baby rhinos. But scientists have saved the sperm of some currently dead male white rhinos, and they’ve managed to create viable embryos using eggs from one of the living rhinos and some of this sperm. They plan to implant it in a surrogate mother (a southern white rhino) soon.
Well, they’re not going to do it by hand — too many to plant. But having a machine do it, that could work. But it has to move over rough terrain. DRONES! That’s it, we’ll use drones!
