Eastern U.S. Needs “Connectivity” to Help Species Escape Climate Change

Georgia Tech Research Scientist Jenny McGuire is interested in spatial questions about the ecological and evolutionary implications of climate change. In a new paper, she and collaborators quantify the concept of climate connectivity in the United States. (Credit: Rob Felt, Georgia Tech)

Improved "climate connectivity" will be needed by species in the Eastern United States.

Gravitational Waves Detected Again

This illustration shows the merger of two black holes and the gravitational waves that ripple outward as the black holes spiral toward each other. The black holes—which represent those detected by LIGO on Dec. 26, 2015—were 14 and 8 times the mass of the sun, until they merged, forming a single black hole 21 times the mass of the sun. In reality, the area near the black holes would appear highly warped, and the gravitational waves would be difficult to see directly. Image credit: LIGO/T. Pyle

Understanding Rogue Ocean Waves May be Simple After All

A 60-foot rogue wave hits the OVERSEAS CHICAGO tanker as it was headed south from Valdez, Alaska in 1993. The ship was running in 25-foot seas when the monster wave hit it on the starboard side. (Credit: Captain Roger Wilson courtesy of NOAA)

A team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere.

Climate Change May Extend Ozone Season in the Southeastern U.S.

Trees in the Southeast United States emit higher levels of isoprene as they are placed under stress from dry conditions. Isoprene is a precursor for the formation of ozone in the atmosphere. This forest is shown near Atlanta, Georgia. (Credit: John Toon, Georgia Tech)

Extreme weather conditions associated with climate change may extend the ozone season in the Southeastern United States.

Optimization Technique Identifies Cost-Effective Biodiversity Corridors

Grizzly bears (Ursus arctos), like this one photographed on the Bridger-Teton National Forest in Wyoming, require large areas to roam and tend to favor mesic, meadow and shrub habitats where there is ample food. (Credit: U.S. Forest Service)

A new optimization technique could help conservation biologists choose the most cost-effective ways of connecting isolated populations of rare, threatened and endangered species living in protected areas.

Unique Bacterial Chemist in the War on Potatoes

A bacterial warrior the only one of its kind? This enzyme is "wacko" in many ways in its breakdown of a poison related to TNT. On top of that, 5NAA-A is known so far only to exist in a single living organism on Earth. Could it be the lone master of a rare bacterial enzymatic kung fu, in the war on potatoes? Or does a genomic clue point to its existence in one other solitary case?
