Like old-growth trees in a forest, old fish in the ocean play important roles in the diversity and stability of marine ecosystems. Critically, the longer a fish is allowed to live, the more likely it is to successfully reproduce over the course of its lifetime, which is particularly important in variable environmental conditions. A new study by […]
In a study analyzing the genomes of 210,000 people in the United States and Britain, researchers at Columbia University find that the genetic variants linked to Alzheimer’s disease and heavy smoking are less frequent in people with longer lifespans, suggesting that natural selection is weeding out these unfavorable variants in both populations. Researchers further find […]
The disastrous 2015-16 Dungeness crab season, delayed and shortened by an unprecedented bloom of toxic algae, is a bitter memory for the West Coast fishing industry. The culprit was domoic acid, a potent neurotoxin produced by marine algae and discovered in 1987 as the cause of amnesic shellfish poisoning. Scientists at UC Santa Cruz have […]
New York, NY )– New research at Columbia University Medical Center (CUMC) has revealed how special molecules help the tongue communicate with the brain to identify the correct taste. Using this knowledge, scientists were able rewire the taste-system of mice to perceive sweet stimuli as bitter tastes, and vice versa. The discovery provides new insights […]
