Researchers have been trialling the use of antibodies to treat Alzheimer’s in humans, but recent studies in mice question whether this is a feasible treatment.

This week’s news

Pitcher plants’ ant trap. Until recently, carnivorous plants fell into two classes, active and passive, based on how they ‘receive’ their prey. Venus fly traps are an example of ‘active’ carnivorous plants, while all pitcher plants were thought to be ‘passive’. However a species of pitcher plant has now been classified as a ‘free energy’ species, as it uses the force of raindrops hitting its unique lid, to fling ants into its pitcher for digestion.
