Science!

Dark energy is real. But we have no clue what it is. My mind keeps going back to ether theory.

Some species of wild snake are capable of parthenogenesis, previously observed in lizards, sharks and some birds. As reptiles have Z and W chromosomes, females can produce both females and males this way, although in many cases of captive 'virgin births' the offspring are not viable.

And in Australia, an obscure species of wasp turns out to be very useful indeed...its parasitic on the extraordinarily poisonous redback spider...and it might be that releasing a few wasps will turn out to be a good way to deal with an infestation.
