Researchers have identified variants in the B4GALT1 gene of Amish people that are associated with low levels of LDL (i.e. “bad”) cholesterol and fibrinogen, a gene involved in blood clotting. In fact, people with variants in this gene are 35% less likely to be diagnosed with heart disease. When the variant was expressed in mice, the animals had similar decreases in LDL cholesterol and fibrinogen. Researchers are hoping to create […]
Naked mole rats are rather famous from a physiological perspective for their amazing ability to live in hypoxic conditions. They do so in part by reducing their metabolic rate. In fact, researchers at the University of Ottawa in Canada showed that reducing environmental oxygen levels to 11% resulted in a 34% decrease in the animal’s metabolic rate. Studies of hypoxia-tolerant goldfish show that the animals respond to hypoxia challenges by […]
If you have ever been to a fast food restaurant, you may have noticed that people are not the only consumers of fast food. In fact, some species of birds are known to frequent fast food chains where they can get a quick meal of food leftover or intentionally dropped by customers. While people may delight in tossing our feathered friends a french fry on occasion, a new study published […]
Image of a fish farm by Vera Kratochvil [Public domain], via Wikimedia Commons Fish farming, i.e. aquaculture, has increased about 6.2% between the years 2000-2012, according to the Food and Agriculture Organization of the United Nations. Fish farms are highly dependent on fish meal as well as fish oil as nutrients for the growing fish. Although rates of farming have increased, the supply of fish meal and oil are predicted […]
Highlights from today’s sessions included: Norelia Ordonez-Castillo, undergraduate student from Fort Hays State University, presented her research on channel catfish. According to Norelia, these fish can become obese so her research was geared towards trying to find out how their receptor for LDL cholesterol differs from rodents and humans. But what I want to know is whether the obese catfish tastes better… Christine Schwartz, Investigator from University of Wisconsin-La Crosse, studied how […]
