    Global Warming Cooks Up 'a Different World' Over 3 Decades

    We were warned. On June 23, 1988, a sultry day in Washington, James Hansen told Congress and the world that global warming wasn't approaching — it had already arrived....Thirty years later, it's clear that Hansen and other doomsayers were right. But the change has been so sweeping that it is easy to lose sight of effects large and small — some obvious, others less conspicuous.… "It would take centuries to a millennium to accomplish that kind of change with natural causes. This, in that context, is a dizzying pace," said Kim Cobb, a climate scientist at Georgia Tech in Atlanta, a professor in the School of Earth and Atmospheric Sciences.

    Team spots new quantum property at frigid temp

    Scientists have spotted a theorized—but never-before detected—property of quantum matter in the lab. The team proved that a particular quantum material can demonstrate electrical dipole fluctuations—irregular oscillations of tiny charged poles on the material—even in extremely cold conditions, in the neighborhood of minus 450 degrees Fahrenheit. The story is based on a Science paper, coauthored by School of Physics Assistant Professor Martin Mourigal.

    Yes, airplanes are germy - but not more so than your house or office, study says

    Airplanes have a bad rep for being disease incubators. Passengers have been advised to pick window seats and turn on their overhead air vent to avoid catching germs, while some even wear surgical masks during flights. But planes aren’t necessarily more germ-ridden as other places we spend our time, according to a recent study. One of the study's authors is School of Mathematics Professor Howie Weiss.

    Airplane germs are 'no worse' than those found in offices and homes, researchers say

    Germaphobes who are wary of airplanes may find some relief in knowing that aircraft are no 'dirtier' than everyday spaces, according to a new study. "There were reasons to believe that the communities of bacteria in an aircraft cabin might be different from those in other parts of the built environment, so it surprised me that what we found was very similar to what other researchers have found in homes and offices," said Howard Weiss, a professor in Georgia Tech's School of Mathematics and the study's corresponding author.

    I saw that. Brain mechanisms create confidence about things seen

    School of Psychology Assistant Professor Dobromir Rahnev discovered a brain function mechanism by which that allows us to be confident of what we are seeing. This article is a copy of the Georgia Tech story explaining Rahnev's findings, published in the Journal of Neuroscience.

    A splash of detergent makes catalytic compounds more powerful

    Researchers in Sandia National Laboratory have discovered that detergents can help optimize the size and shape of catalytic compounds for various reactions. They have enlisted the aid of Younan Xia, a pioneer in nanomaterial synthesis to accelerate the work. Xia has joint appointments in the School of Chemical and Biomolecular Engineering and the School of Chemistry and Biochemistry., Jun 1, 2018

    The Great Barrier Reef Has a Surprisingly Morbid History

    Kim Cobb comments in another coverage of a new study in Nature Geoscience. The study found that the Great Barrier Reef has experienced death and resurrection five times in the past 30,000 years. Cobb, a professor in the School of Earth and Atmospheric Sciences, wasn't involved in the study. “We can and should use this study to gather the clues to reef resilience through dramatic climate changes of the past,” Cobb says.

    The Great Barrier Reef has had five near-death experiences in the past 30,000 years

    According to a new study, entire stretches of Australia’s Great Barrier Reef have died and eventually recovered five times in the past 30,000 years—and it may be happening again today. The study “holds some really important lessons” for understanding how resilient corals are in the face of change, and how quickly they recover after catastrophic events, says Kiim Cobb. She is a professor in the School of Earth and Atmospheric Sciences. She wasn’t involved in the work.

    No sun? No problem — this solar panel harvests energy from raindrops, too

    Solar panels typically harvest energy from sunlight during the day. But how about a solar cell that generates electricity even when the rain falls in the middle of the night? Researchers in  China's Soochow University have demonstrated such an all-weather device. What makes it possible is a triboelectric nanogenerator, which converts motion into electricity. Researchers including Zhong Lin Wang first proposed the concept of a hybrid solar cell and triboelectric nanogenerator in a paper published in 2015. Wang is a professor in the School of Materials Science and Engineering with an adjunct appointment in the School of Chemistry and Biochemistry.
