    Trillions Upon Trillions of Viruses Fall From the Sky Each Day

    Here's a thought to make your skin crawl: Viruses are the most abundant entities on the planet by far. And trillions upon trillions fall from the sky every day, according to a recent study that was the first to tell us just how many viruses float above the Earth. Now you know why School of Biological Sciences Professor Joshua Weitz was one of three researchers calling for a better understanding of viral ecology in a 2017 editorial in Nautilus. There is a silver lining to this virus deluge; some of them may actually be good for their hosts.

    Atlantic Circulation Weakening: No, We're Not All Gonna Die (I Mean, Not Because Of This)

    Two new studies published in Nature that show a slowing down of Atlantic circulation have inspired doomsday scenarios in recent headlines. But Annalisa Bracco, of the School of Earth and Atmospheric Sciences, assures us that it's not as drastic as we might think. She points out that other researchers' work don't show any significant decline at all. So, is the collapse of the Gulf Stream imminent? "No," Bracco says.

    Heat waves over the ocean have ballooned and are wreaking havoc on marine life

    Heat waves over the world’s oceans are becoming longer and more frequent, damaging coral reefs and creating chaos for aquatic species. Kim Cobb, of the School of Earth and Atmospheric Sciences, says that most of the effects of these heat waves are "invisible" to humans. The real damage will be to marine life. Cobb continues, "These heat waves will only get worse, with untold impacts on ocean resources that we all depend on for food, recreation, and other ecosystem services."

    Bad news! Extreme ocean heat waves are a thing, and they're getting worse

    During the greater heat wave event that caused the 2015 South California marine heat wave, a number of sea dwelling creatures, including sea lions, birds, and quite possibly nearly 50 whales, died. A new study shows that marine heat waves are becoming longer and more frequent. "There is no question that there's a trend," says Emanuele Di Lorenzo of the School of Earth and Atmospheric Sciences, who was asked to comment on the study.

    3-D printer emissions raise concerns and prompt controls

    3-D printers deposit molten plastic layer upon layer, cranking out toys, guns, artificial limbs, and countless other objects.The surging market has made desktop versions affordable for schools and librariers. But these smaller versions come with a cost. Printers emit volatile organic compounds (VOCs) and other particles. Rodney Weber of the School of Earth and Atmospheric Sciences comments on the data about these emissions.

    Chemically Unique Hybrid Substance Could Redefine Semiconductor Effectiveness

    "A study spearheaded by scientists at Georgia Tech has found that an obscure class of crystal could improve the way we light and power our world. The subatomic behavior of these crystals is fluid, dynamic and, frankly, bewildering in the context of some established laws of quantum physics. However, this latest study, completed early this month, shows that weirdness doesn’t necessarily mean ineffectiveness. In fact, the substance could be the key to more efficient electric lighting—perhaps even across a full rainbow of colors." The study is by School of Chemistry and Biochemistry and School of Physics Professor Carlos Silva and Ph.D. student Felix Thouin., Mar 26, 2018

    How Not to Get Sick on a Plane? Choose Your Seat Wisely

     During the height of the flu season, researchers from Georgia Tech and Emory University took four crowded flights from Atlanta to the West Coast. They observed passenger and crew movements, took air and surface samples, and listened for anyone who was coughing. The researchers were gathering data for a new study on how infectious diseases are transmitted among air travelers. School of Mathematics Professor Howard Weiss was a co-author of the study. The results of the research continue to get mainstream media attention, including this New York Times story and an article in Smithsonian Magazine.

    How Much Do You Poop in Your Lifetime?

    "A person's accomplishments accumulate over years and decades. Something else accumulates, too — their poop. The quantities of poop that people leave behind during an individual bathroom break can vary widely, depending on age, body weight, diet, exercise and other factors." David Hu's research on how long it takes animals to defecate informs this story. Hu is affiliated with the Schools of Mechanical Engineering, Biological Sciences, and Physics.
