A new study relates liquid fructose intake to fatty liver disease

A new study reveals that liquid fructose intake, even in high-fat diets, can accelerate liver fat accumulation and hypertriglyceridemia. The study found that fructose induces an increase in the synthesis of fatty acids in the liver and inhibits lipid oxidation, leading to the emergence of non-alcoholic fatty liver disease (NAFLD).

Field cage study highlights safety of classic biological control agent against devastating invasive fruit fly

A field cage study in Switzerland found that a parasitoid was highly specific to the invasive fruit fly Drosophila suzukii, with only 15% parasitism rate. In contrast, non-target species showed a very rare parasitism rate of 0.02%. The results support previous laboratory experiments and suggest low risk for non-target effects.
