Losing your sense of smell may help you lose weight—and it has nothing to do with taste

When Andrew Dillon, a cell biologist at the University of California Berkeley, set out to study the effect of the sense of smell on weight in mice, he assumed that he’d find that mice without a sense of smell would enjoy food less, eat less, and therefore weigh less. Scientists have known that smell shapes the way […]

The worrying effects of working more and sleeping less

“Back in the 1940s people were sleeping on average just a little bit over eight hours a night, and now in the modern age we’re down to around 6.7, 6.8 hours a night,” says Matt Walker, professor of neuroscience and psychology at the University of California, Berkeley. “So that’s a staggering loss of sleep within the […]

Is sense of smell linked to being fatter or thinner?

Would you be willing to give up the smell of fresh-baked chocolate chip cookies or a pizza right out of the oven if it meant slimming down? A new study showed that mice that lost their sense of smell didn’t gain weight even when they ate the same high-fat diet as mice that could smell and did gain […]

Improved imaging technique reveals synaptic transmission at quantal resolution in fruit fly larvae

Synapses, including those using glutamate as a neurotransmitter, vary greatly in pre- and post-synaptic transmission properties. How differences in pre-synaptic release characteristics, short term plasticity, and homeostatic stability-promoting regulation relate to one another and to this diversity is poorly understood. At the University of California, Berkeley, Dr. Ehud Isacoff and his group used the Drosophila larval neuromuscular junction (NMJ), […]

Smelling your food makes you fat

Our sense of smell is key to the enjoyment of food, so it may be no surprise that in experiments at the University of California, Berkeley, obese mice who lost their sense of smell also lost weight. What’s weird, however, is that these slimmed-down but smell-deficient mice ate the same amount of fatty food as […]

Does my sense of smell make me look fat? In mice, the answer seems to be yes

Having an exceptionally keen sense of smell would seem to be an unmitigated blessing: It can provide early warning of dangers, detect the presence of an attractive mate, and enhance the gustatory delight of a delicious meal. But when you’re a mouse (or, perhaps, a human) and fattening food is all around, a new study finds that […]

Mice shed weight when they can’t smell—but not because they stop eating

When you have a stuffy nose, a slice of freshly baked apple pie tastes like mush. But not being able to smell your food could have a surprising effect on your metabolism, potentially helping you remain thin even when you eat fatty foods, a new study in mice suggests. “This is a very exciting study, […]

Brain Changes Accompany Development of Metamemory from Childhood to Adolescence

Being able to assess our own memories helps us to avoid errors and prompts us to collect more information to fill the gaps. Psychologists know that this ability is present in elementary school-age children. Now a new study shows how this “metamemory” improves from childhood through adolescence, with accompanying changes in brain structure. The work […]
