PHASE UTILITY. "Optoelectronic phase change materials (PCM) have markedly different optical reflectivity and electrical conductivity in their disordered and ordered phases. They can be switched rapidly and reversibly between their better conducting crystalline and the more insulating amorphous phases. Owing to their properties, PCMs are used as non-volatile memory materials and bear promise as materials for programmable logic circuits." https://lnkd.in/eC9wHtZ View in LinkedIn

FRAGMENT IN NATURE continues this weekend with the theme of the interaction of the microbiome with taste receptors and that effect on satiety, food selection and health. These is little literature on the effects of the microbiome directly on taste receptors in the mouth, but intuitively, it is a likely control point for these symbiotic bacteria in their host nutritional status.

GUT BIOME SYMBIOSIS. "Gut bacteria aid digestion by breaking down otherwise indigestible plant fibers into short-chain fatty acids that intestinal cells can access." The normal microbiome plays a key role in maintaining our health, that we know. But gut fermented SCFAs turn out to be critical microbial signals to the host, as well as providing nutrition. https://lnkd.in/eCbaTsv View in LinkedIn

ACUTE CHANGES IN BUDS. It is clear that our taste buds and their taste receptors can change acutely in short time intervals, affecting food preferences and caloric intake. The control of these changes is poorly understood. Food preferences, caloric intake, and satiety are undoubtedly controlled, at least in part, by taste receptor composition. View in LinkedIn

ACUTE CHANGES IN TASTE RECEPTORS. "Our taste preferences may fluctuate with our hormones...many pregnant women in their first trimester can't stand the sight of vegetables...pregnant women crave foods that tend to be high energy sources." Is this hormonally regulated? Maternal biome changes occur throughout pregnancy. https://lnkd.in/eDcVrhp View in LinkedIn

CHANGING TASTE BUDS. "Our tongues appear to become more sensitive to fat if we eat less of it. And the more sensitive our tongues become, the less butter, meat, dairy, and eggs study subjects ate. We also get a blunted taste for fat if we eat too much. This diminished fat sensitivity has been linked to earring more calories. This numbing of our ability to taste fat can happen in just a few weeks." https://lnkd.in/e7xGG4q View in LinkedIn

ADAPTIVE TASTE RECEPTORS. "The longer we eat healthier foods, the better they taste" particularly low fat and low salt diets, an acute adaptation of our taste buds. https://lnkd.in/exh7MF5 View in LinkedIn

WESTERN DIETS, combined with increased pollutants, and stress cause the release of inflammatory molecules in the body. Inflammation is thought today to be an early marker of many diseases. Poor diet, pollutants and stress also negatively impact the microbiome, which plays a key role in maintaining host health, and leads to disbalance and pathology. https://lnkd.in/eAuv5UZ View in LinkedIn

HOST REPROGRAMMING. There are many examples of microbes affecting their hosts' mood and behavior. As our microbiomes get thrown off balance by diet, pollution and stress, allowing undesirable microbiota to become dominant, these new players may adversely affect our own mood and behaviors. https://lnkd.in/eknVNSM View in LinkedIn

BACTERIAL HIJACKINGS. Gut microbes can manipulate host eating behavior by hijacking their host's nervous system. Evidence shows that microbes can have dramatic effects on behaviors through the microbiome-gut-brain axis. https://lnkd.in/eknVNSM View in LinkedIn
