Cutting a specific taste nerve in rats reduced their intake of sugary and high-energy foods, but did not change how much fat they ate or their overall meal patterns. This reveals a direct link between this nerve and the drive to consume sweet, calorie-rich foods, separate from fat cravings.

A large study of patients with a common inherited nerve disease (Charcot-Marie-Tooth) found that a specific gene variant, previously thought to cause disease only when inherited from both parents, can also cause it when inherited from just one parent. This means doctors should test for this gene in all patients with suspected inherited neuropathy.
