Chinese leaders, grappling with some of the world's worst air pollution, have long assumed the answer to their woes was gradually reducing the level of smog-forming chemicals emitted from power plants, steel factories and cars. But new research suggests another factor may be hindering China's efforts to take control of its devastating smog crisis: climate change. One of those studies is by Yuhang Wang, a professor in the School of Earth and Atmospheric Sciences at Georgia Tech.

To explore the mathematical possibilities of alternative geometries, mathematicians imagine such ‘non-Euclidean’ spaces, where parallel lines can intersect or veer apart. Now, with the help of relatively affordable VR devices, researchers are making curved spaces — a counter-intuitive concept with implications for Einstein’s theory underlying gravity and also for seismology — more accessible. They may even uncover new mathematics in the process. “You can think about it, but you don’t get a very visceral sense of this until you actually experience it,” says Elisabetta Matsumoto, a physicist at the Georgia Institute of Technology in Atlanta.

What made the winter smog in China so bad in 2013 and in the winters since? Two new studies...argue that climate change will make this kind of smog event much more common. And, remarkably, one of them - by Yuhang Wang and others at the School of Earth and Atmospheric Sciences at Georgia Tech - asserts that the Chinese smog of January 2013 was worsened by two weather phenomena thousands of miles away.

NASA has selected four new research teams to join the existing nine teams in SSERVI (Solar System Exploration Research Virtual Institute) to address scientific questions about the Moon, near-Earth asteroids, the Martian moons Phobos and Deimos, and their near space environments, in cooperation with international partners. One of the teams is from Georgia Institute of Technology, led by School of Chemistry and Biochemistry Professor Thomas Orlando.

While NASA already has plenty of scientists, it still regularly works with research teams from various universities and non-profit orgs. It even created the Solar System Exploration Research Virtual Institute (SSERVI) to oversee some of its collaborations. In fact, the agency has added four new teams looking to study the moon, near-Earth asteroids and Martian moons Phobos and Deimos to SSERVI's roster. One of the teams is from Georgia Institute of Technology, led by Thomas Orlando, a professor in the School of Chemistry and Biochemistry. .

Bright radiation emitted by neighboring galaxies likely fueled the rapid growth of supermassive black holes in the early universe, a new study shows. John Wise, an associate professor in the School of Physics, is a co-author of the study.

Kim Cobb, professor in the School of Earth and Atmospheric Sciences, comments on a new research study of Australia's Great Barrier Reef. The study indicates that rising ocean temperatures are doing more damage to coral reefs than previously thought. "A future that we thought was decades coming is basically here," Cobb says.

Climate change in the polar regions may have worsened winter haze problems in China, according to a study....The study published in the U.S. journal Science Advances suggests that melting Arctic sea ice and increasing Eurasian snow, both caused by global climate change, have shifted China's winter monsoon, helping create stagnant atmospheric conditions that trap pollution over the country's major population and industrial centers. "Emissions in China have been decreasing over the last four years, but the severe winter haze is not getting better," said Yuhang Wang, a professor at the Georgia Institute of Technology, who led the study. Yuhang Wang is a professor in the School of Earth and Atmospheric Sciences.

“We will make our skies blue again,” vowed Chinese Premier Li Keqiang earlier this month, pledging aggressive new steps to combat China’s notorious smog....But a study adds a possible wrinkle to China’s fight for blue skies. Climate change – in particular, the melting of Arctic sea ice – makes the country's smog even more likely to stay where it is. “The ventilation is getting worse,” one of the study’s co-authors, Georgia Tech atmospheric scientist Yuhang Wang, told Science Magazine. Yuhang Wang is a professor in the School of Earth and Atmospheric Sciences. The report he co-authored was first published in Science Advances.

Negotiating uneven ground can be challenging for people who use lower-limb prostheses to walk, so researchers spend time searching for solutions that will allow greater stability in these situations. Manufacturers of prosthetic feet have contributed to a solution by adding multiaxial features that better reproduce the behavior of human ankles, which can stiffen as the terrain warrants. However, School of Biological Sciences Senior Lecturer W. Lee Childers found that there was a lack of evidence evaluating the prosthetic ankle stiffness as it relates to the user’s dynamic balance and gait over uneven terrain. Thus, his continuing research focuses on defining the effect of multiaxial stiffness on gait stability among people with unilateral transtibial amputations....“The main focus of this work was to justify that it is a good thing for prosthetic feet to have multiaxial function,” Childers says, because if it can prevent falls among its users, its value is demonstrated to the payers.
