Using genetics, it is possible to uncouple higher adiposity from its adverse metabolic effects and show that some obesity-associated conditions may benefit from treating the metabolic effects alone, whilst others may benefit more from weight loss.

One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

Overgrowth of the yeast Pichia kudriavzevii within the neonatal gut microbiota increases allergic airway disease severity later in life and may be inhibited by short-chain fatty acids.

Olfactory neurons of insects, once thought to express only a single type of olfactory receptor, exhibit widespread co-expression of receptors from multiple chemosensory gene families.

A new method to infer the spatial history of genetic ancestors from a sequence of trees along a recombining genome.

Mice can use self-motion cues to learn a cognitive map thereby permitting them to take shortcut trajectories in an open maze without requiring prior experience of such routes.

Current models of Alzheimer's disease that put mitochondria as an endpoint of disease should be reconsidered because genetic defects affecting mitochondria by themselves can also regulate Alzheimer’s disease risk factor apolipoprotein E (APOE) expression and secretion.
