Training your brain to prefer healthy foods Posted: 01 Sep 2014 09:34 AM PDT It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods, according to new research.

Changing global diets is vital to reducing climate change, researchers say Posted: 31 Aug 2014 12:02 PM PDT Healthier diets and reducing food waste are part of a combination of solutions needed to ensure food security and avoid dangerous climate change, say the team behind a new study.

Surprising discovery: HIV hides in gut, evading eradication Posted: 29 Aug 2014 02:54 PM PDT Some surprising discoveries about the body's initial responses to HIV infection have been made by researchers. One of the biggest obstacles to complete viral eradication and immune recovery is the stable HIV reservoir in the gut. There is very little information about the early viral invasion and the establishment of the gut reservoir. "We want to understand what enables the virus to invade the gut, cause inflammation and kill the immune cells," said the study's lead author.

Stop and listen: Study shows how movement affects hearing Posted: 27 Aug 2014 11:17 AM PDT When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. The interplay between movement and hearing has a counterpart deep in the brain. A new study used optogenetics to reveal exactly how the motor cortex, which controls movement, can tweak the volume control in the auditory cortex, which interprets sound.

Neuroscientists reverse memories' emotional associations: Brain circuit that links feelings to memories manipulated Posted: 27 Aug 2014 10:16 AM PDT Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach probably makes you feel happy, while reflecting on being bullied provokes more negative feelings. A new study from neuroscientists reveals the brain circuit that controls how memories become linked with positive or negative emotions.
