Pain & Pleasure : Cloning of the First Opioid Receptor
Prof. Brigitte Kieffer’s scientific research has concentrated on a group of receptor proteins - the mu, delta and kappa opioid receptors — which are found in the cell membranes of neurons in the central and peripheral nervous system and, when activated by natural peptides released under specific conditions, reduce pain, help to cope with stress and drive “pleasurable” vital behaviors including sexuality, food consumption and social interactions. These same receptors can also be activated by drugs derived from opium, including heroin and morphine, which hijack the body’s natural neuromodulatory system to bring instant relief and reward. With regular use, tolerance to these drugs develops so that higher doses are required to obtain the same effect, and adaptations occur in the brain leading to the well-known syndromes of morphine dependence and heroin addiction.
To understand the contribution of each opioid receptor, and the complex interactions between them, to pain control, addictive behaviors and mood disorders, Prof. Kieffer needed to understand how they function at the molecular level. Despite the huge technical difficulties of working with opioid receptors, her persistence and tenacity resulted in the first ever cloning and sequencing of a gene encoding an opioid receptor, the delta receptor. This feat had eluded the scientific community for two decades, despite many attempts, and opened up a whole new field of research in neurobiology.

The Real Reason Your Cat Is A Picky Eater
Cats only have about 500 taste buds, while humans have around 9,000. However, their sense of smell is much stronger than ours, so cats typically enjoy the smell of their food more than the actual taste.

The Milk-Industrial Complex
Readers of Aaron’s blog know of his beef with the milk industrial complex. Why does milk, of all beverages, get a pass in our efforts to reduce everyone’s caloric intake? Why is it encouraged, when all others are shunned? Is it because you need the calcium? Is it because it makes your bones stronger? Watch, and learn why the milk emperor has no clothes.
