Mining Public Big Data yields Genetic Clues in Complex Human Diseases

March 27, 2015 11:35 am | by Beth Miller, Washington University in St. Louis | News | Comments

Big data: It’s a term we read and hear about often, but is hard to grasp. Computer scientists tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases. Through a novel method of analyzing these big data, they discovered a region encompassing the gephyrin gene on chromosome 14 that underwent rapid evolution after splitting in two...

Mathematicians Solve 60-year-old Fermi-Pasta-Ulam Problem

March 24, 2015 3:05 pm | by University of East Anglia | News | Comments

A 60-year-old math problem first put forward by Nobel laureate Enrico Fermi has been solved. In 1955, a team of scientists led by Fermi used a computer for the first time to try to solve a numerical experiment. The outcome wasn’t what they were expecting, and the complexity of the problem underpinned the then-new field of non-linear physics and paved the way for six decades of new thinking. Chaos theory is just one of the theories...

Strange Viruses Discovered in Deep Ocean

The intraterrestrials, they might be called. Strange creatures live in the deep sea, but few are odder than the viruses that inhabit deep ocean methane seeps and prey on single-celled microorganisms called archaea. The least understood of life's three primary domains, archaea thrive in the most extreme environments: near hot ocean rift vents, in acid mine drainage, in the saltiest of evaporation ponds and in petroleum deposits.

A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. The "Carolina Butcher" was a nine-foot-long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems, such as armored reptiles and early mammal relatives.

Self-organized Criticality: One Fractal Quantifies Another

To humor mathematicians, picture a pile of sand grains — say, a billion — in one square of a vast sheet of graph paper. If four or more grains occupy a single square, that square topples by sending one grain to each of its four neighboring squares. Keep zooming out so the squares become very small, and something strange happens — the sand still “remembers” that it used to live on a square lattice, and a distinctive pattern emerges.
