For something that has evolved with us over millions of years, and remains part of our physiology over our entire lives, our gut microbiome, oddly, remains somewhat of a mystery. Comprised of trillions of microbes of at least a thousand different species, this community of bacteria, viruses, protozoa and fungi in our gastrointestinal tracts is unique to each individual and has been found to be intimately connected to various fundamental aspects of our fitness, from our immunity to our metabolism and mental health.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/3Oriz0AS0BY" height="1" width="1" alt=""/>Thu, 14 May 2020 11:58:47 EDThttps://www.sciencedaily.com/releases/2020/05/200514115847.htmhttps://www.sciencedaily.com/releases/2020/05/200514115847.htmAll disease models are 'wrong,' but scientists are working to fix that

What rules shaped humanity's original social networks? The earliest social networks were tightly knit cultural groups made of multiple biologically related families. That single group would then develop relationships with other cultural groups in their local area. Researchers used statistical physics and computer models common in evolutionary biology to explain the origin of common community structures documented by cultural anthropologists around the world.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/1fHmoniiLIQ" height="1" width="1" alt=""/>Tue, 21 Jan 2020 11:30:24 ESThttps://www.sciencedaily.com/releases/2020/01/200121113024.htmhttps://www.sciencedaily.com/releases/2020/01/200121113024.htmCreating learning resources for blind students

Mathematics and science Braille textbooks are expensive and require an enormous effort to produce -- until now. A team of researchers has developed a method for easily creating textbooks in Braille, with an initial focus on math textbooks. The new process is made possible by a new authoring system which serves as a 'universal translator' for textbook formats.

Classical physics is characterized by the equations describing the world. Yet our day-to-day experience is struck by this deterministic vision of the world. A physicist has been analyzing the classical mathematical language used in modern physics.
