Many Cambrian fossils are simply spines and sclerites unassociated with any body. Few of the exceptionally-preserved Cambrian freaks come with spines attached, and some of the most prominent of these are the chancelloriids. Originally described as sponges by Charles Doolittle Walcott back in 1920 (Walcott, 1920), modern researchers have found that the spines are very similar to those […]

Think of it as interval training for the dinner table. Proponents of fasting style diets will be first to tell you there are health benefits, heck we've even covered some of the science here at the labs. Well new research shows that putting people on a intermittent fasting (or IF) diet may mimic some of the benefits of actual fasting, and that (ironically enough given their popularity) adding antioxidant supplements counteracts those benefits....

Babies link the sound of a word with the image of an object in their early learning of language and this is an important ability. How do they come to have this mechanism? Are there predispositions to making links between sounds and images? Research by Asano and others (citation below) shows one type of link. […]... Read more »

I want to bring the paper from Tea Skaaby and colleagues  to your attention for today's brief blog post and their observation that there may be: "a possible protective role of a higher vitamin D status on autoimmune disease". Autoimmune disease by the way, reflects a breakdown in communication and tolerance of 'self' whereby the body attacks healthy tissue.Their findings, based on an analysis of "a total of 12,555 individuals from three population-based studies with measurements of vitam........
