It makes sense that foods that smell great are associated with gaining weight. Our sense of smell is a key to our eating enjoyment, and a dish that is enticingly aromatic will tend to induce us to overly consume.
But a series of experiments at UC Berkeley puts a twist on these assumptions. Researchers found that mice modified to possess super abilities to smell got fatter than normal mice, though both ate the same diet. The findings, if translatable to humans, suggest that the odor of what we eat may play a role in how the body burns calories. If you can't smell your food, you may burn it rather than store it.
This has relevance for people who have lost their sense of smell due to age, injury or disease. Often, they become anorexic. Part of the reason is loss of pleasure in eating, which can lead to depression, which is itself an appetite depressant. The new study points to a neurological cause as well, and perhaps a new path for treatment.
Malaria is a serious public health threat in the nation of Mali, as it is in tropical and sub-tropical regions around the world (212 million cases globally in 2015). Looking for new ways to fight back, researchers have experimented with pruning the flowers off non-native shrubs that mosquitoes feed upon.
In tests, they found that in villages with the pruned plants, mosquito numbers fell 60 percent and the number of older female mosquitoes — which are more likely to spread malaria — dropped to the same level as in villages without the invasive shrubs.
The results suggest another way to improve public health and reduce the impact of invasive plant species.
Body of Knowledge
The average human blinks 15 to 20 times per minute, 1,200 times per hour, 28,800 times per day. Our eyes are closed roughly 10 percent of waking hours due to blinking. Women blink nearly twice as often as men. Blinking helps lubricate the eyes and provide protection from dust or other debris, but researchers say it may serve another purpose: Briefly closing our eyes provides a momentary respite for the brain, allowing it to "go offline" and reset itself.
