Researchers discover how we perceive bitter taste      (via sciencedaily.com)     Original source 

A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-tasting substances bind to TAS2R14 and how they activate them. The findings may lead to the development of drugs that targeting taste receptors.

Connecting lab-grown brain cells provides insight into how our own brains work      (via sciencedaily.com)     Original source 

Researchers have developed a technique to connect lab-grown neural 'organoids' (three-dimensional developmental brain-like structures grown from human stem cells) using axonal bundles, similar to the connections between regions in the human brain. This technique allows brain networks to be better represented experimentally in the lab, and will improve understanding and studies of network-related brain disorders.
