Rats fed a high fat diet were less sensitive to a hormonal stop eating signal than rats on a low fat diet when they were given access to a high calorie, high fat snack that the animals find yummy.
Dr. Mihai Covasa, assistant professor of nutritional sciences and a member of the Penn State Neuroscience Institute, led the study. He says, "When we gave the rats doses of a stop eating hormone, the rats on the low fat diet significantly suppressed their intake of the snack but not the rats on the high fat diet."
Covasa adds, "These results suggest that a long-term, high-fat diet may actually promote short-term overconsumption of highly palatable foods high in dietary fat by reducing sensitivity to at least one important feedback signal which would ordinarily limit eating."

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
