Efficient synthesis of ginkgo compound could lead to new drugs, 'green' insecticides

Chemists have invented an efficient method for making a synthetic version of the plant compound bilobalide, which is naturally produced by gingko trees. It's a significant feat because bilobalide — and closely related compounds — hold potential commercial value as medicines and 'green' insecticides.

How do ketogenic diets affect skin inflammation?

Not all fats are equal in how they affect our skin, according to a new study. The investigators found that different ketogenic diets impacted skin inflammation differently in psoriasiform-like skin inflammation in mice. Ketogenic diets heavy in medium-chain triglycerides (MCTs) such as coconut, especially in combination with omega-3 fatty acids from fish oil and plant sources like nuts and seeds, exacerbated psoriasis.

How hunger makes food tastier: A neural circuit in the hypothalamus

Using optogenetic and chemogenetic techniques, researchers have identified brain circuits underlying hunger-induced changes in the preferences for sweet and aversive tastes in mice. These circuits involved Agouti-related peptide-expressing neurons, which projected to glutamate neurons in the lateral hypothalamus. From there, glutamate neurons projecting to the lateral septum increased sweetness preferences, and glutamate neurons projecting to the lateral habenula decreased sensitivity to aversive tastes.

Habitual tea drinking modulates brain efficiency: Evidence from brain connectivity evaluation

The researchers recruited healthy older participants to two groups according to their history of tea drinking frequency and investigated both functional and structural networks to reveal the role of tea drinking on brain organization.
