Gravitational Waves Detected 100 Years After Einstein’s Prediction

Visualization of the first binary black black hole coalescence discovered, GW150914, which was announced on February 11, 2016. The two black holes are in orbit around each other, getting closer together, losing energy to gravitational waves, seen here as colored contours.The two white spheres are the black holes, colored white for visibility. The image was taken from a binary/simulation that was created by Georgia Tech's team, including Matt Kinsey, Karan Jani and Michael Clark.

Georgia Tech faculty, postdocs and student researchers play a crucial role in the first-ever observation of a gravitational wave.

An Animal That “Flies” through the Ocean

Small zooplankton snails don't paddle like most small water animals. They "fly" with wings.

Bacterial Biofilms in Hospital Water Pipes May Show Pathogenic Properties

Researchers have described microbial communities found in shower hoses at a major U.S. hospital.

Researchers List “Seven Chemical Separations to Change the World”

Thermally-based industrial chemical separation processes such as distillation now account for 10 to 15 percent of the world’s annual energy use. Researchers at the Georgia Institution of Technology are suggesting seven energy-intensive separation processes they believe should be the top targets for research into low-energy purification technologies. Shown are (l-r) David Sholl and Ryan Lively. (Credit: Rob Felt, Georgia Tech)

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)
