Football Displays Real-time Fractal Dynamics

March 19, 2014 4:13 pm | by Springer | News | Comments

Football, aka soccer, fascinates millions of fans, almost all of them unaware that the game is subject to the laws of physics. Despite their seemingly arbitrary decisions, players obey certain rules, as they constantly adjust their positions in relation to their teammates, opponents, the ball and the goal. Scientists have analyzed the time-dependent fluctuation of both the ball and all players’ positions throughout an entire match.

Obama Unleashing Power of Data on Climate Change

March 19, 2014 1:55 pm | by Seth Borenstein, AP Science Writer | News | Comments

The Obama administration hopes to fight global warming with the power of numbers, maps and even gaming-type simulations. The White House on March 19, 2014, announced an initiative to provide private companies and local governments better access to already public climate data. The idea is that, with this localized data, they can help the public understand the risks they face, especially in coastal areas where flooding is a big issue.

A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible. The model is the first to represent the start of a supernova collapse in three dimensions, said its developer

Number of Days without Rain to Dramatically Increase

March 14, 2014 3:49 pm | by UC San Diego | News | Comments

By the end of the 21st century, some parts of the world can expect as many as 30 more days a year without precipitation, according to a new study by Scripps Institution of Oceanography, UC San Diego researchers. Ongoing climate change caused by human influences will alter the nature of how rain and snow falls; areas that are prone to dry conditions will receive their precipitation in narrower windows of time.

Let There be Light: Simulations Re-create X-rays Emerging from the Neighborhood of Black Holes

February 18, 2014 4:33 pm | by Aaron Dubrow, NSF | News | Comments

Black holes may be dark, but the areas around them definitely are not. These dense, spinning behemoths twist up gas and matter just outside their event horizon, and generate heat and energy that gets radiated, in part, as light. And when black holes merge, they produce a bright intergalactic burst that may act as a beacon for their collision.
