...t al. show that worms have a good understanding of high school physics even without reading the textbook. The authors placed worms within an electric field and observed, as expected, that the worms crawled toward the negative pole. The threshold field strength was about 3 V/cm. However, rather than going ...Study finds Western-style 'meat-sweet' diet increases risk of breast cancer in postmenopausal women
...ong overweight postmenopausal women. Specifically, high intake of the meat-sweet pattern was associated with a greater than twofold increased risk of ER+ breast cancer among these women. The results showed no overall association of breast cancer risk with the vegetable-soy pattern. Our study suggests ...Insulin sensitizer also serves as energy-conserving signal to the brain
...reted exclusively by WAT, is present at relatively high concentrations in the circulation and has been shown to increase the bodys response to insulin.
