Hungry Again? Your Memory May Be to Blame

Hungry Again? Your Memory May Be to Blame | Science News | Scoop.it
Hunger would seem to be a fairly straightforward instinct: Depending on how much you eat, you either will or you won't be hungry afterward. As it turns out, our relationship to food may not be so simple.

A new study, published this week in the journal PLoS ONE, adds a new wrinkle by suggesting our short-term memory also may play a role in appetite. Several hours after a meal, the study authors found, people’s hunger levels were predicted not by how much they’d eaten, but rather by how much food they’d seen in front of them—in other words, how much they remembered eating.

Synaptic plasticity – the ability of the synaptic connections between the brain's neurons to change and modify over time -- has been shown to be a key to memory formation and the acquisition of new learning behaviors.

Sunshade geoengineering more likely to improve global food security, research suggests

Sunshade geoengineering more likely to improve global food security, research suggests | Science News | Scoop.it

Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing Earth to get hotter and hotter. There are concerns that a continuation of these trends could have catastrophic effects, including crop failures in the heat-stressed tropics. This has led some to explore drastic ideas for combating global warming, including the idea of trying to counteract it by reflecting sunlight away from Earth. However, it has been suggested that reflecting sunlight away from Earth might itself threaten the food supply of billions of people.
