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.

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.

Crowdsourced Rain Samples Map Hurricane Sandy's Evolution

March 11, 2014 7:36 pm | by University of Utah | News | Comments

A unique method to collect rain water samples during Hurricane Sandy has revealed the storm's chemical "signature" with a new level of detail. The technique may also lead to weather model advances that will ultimately improve storm prediction. Hurricane Sandy, also known as Superstorm Sandy, was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. Nearly 300 people perished along the path of the storm.

Dimer Molecules Help Gauge Exoplanet Pressure, Aid Hunt for Life

March 4, 2014 8:34 pm | by Peter Kelley, University of Washington | News | Comments

Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in the atmosphere of an alien world.

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.
