Two UGA students finalists in Radiolab contest to name one of Earth's quasi-moons

Though they might not be seen, they can be named – voting is open through Dec. 31. Asteroids orbiting the sun in a similar path to Earth's, quasi-moons escort our planet on its journey a few centuries at a time. The science podcast Radiolab and the International Astronomical Union (IAU) — the organization that assigns official names to quasi-moons and their surface features — announced a contest earlier this year to name the…

New research challenges long-standing paradigm on planet formation

Two theories of planet formation have long-dominated astronomy - the first theory, “core accretion,” posits that planets grow slowly from particles of dust ultimately forming pebbles, then boulders, which coalesce to form planets over tens of millions of years.  The second theory – “gravitational instability,” in which planets form quickly from direct collapse of gas and dust, requiring hundreds to thousands of years instead – received new…

UGA research team receives USDA APHIS funding for development of a rapid diagnostics platform for SARS-CoV-2

A person with COVID-19 might transmit SARS-CoV-2 to domestic cats and dogs (and perhaps other pets) in the same way that an infected animal could possibly transmit it to another individual. In addition, lions, tigers, pumas, snow leopards and non-human primates from zoos or wildlife refuges in the U.S. and other countries have been confirmed infected with SARS-CoV-2, while infections have also been reported in white-tailed deer, both wild and…

UGA researchers discover new planet outside solar system

A University of Georgia research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it. A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars. The newly published findings represent a first step toward using machine learning to…

Next-generation nanophotonics devices and applications come into view

Densely-packed solar cells that fit on a car and efficiently transfer light to electricity; point-of care medical diagnostic tools; major advances in communication, sensing and imaging – all of these plus many more depend on interaction of light with the material world at a very small scale, also known as nanophotonics. What makes nanophotonics so interesting to scientists and so promising across a broad array of industry is the subject of a new…

UGA team develops faster, cheaper COVID tests

A University of Georgia nanotechnology research group entered the race to develop a rapid test for COVID-19 in August 2020, running experiments on a new sensor for an American manufacturing company. The group, led by Yiping Zhao and Ralph Tripp, tested nanotechnology-based optical sensors designed for COVID-19 detection and saw the potential for their home-grown technology. In March 2022, the group filed a patent application and published…

Sensors eliminate sparking risk in hydrogen vehicles

Hydrogen as a clean, renewable alternative to fossil fuels is part of a sustainable-energy future, and very much already here. However, lingering concerns about flammability have limited widespread use of hydrogen as a power source for electric vehicles. Previous advances have minimized the risk, but new research from the University of Georgia now puts that risk in the rearview mirror. Hydrogen vehicles can refuel much more quickly and go…

Teaching physics via Zoom

When she started her stint as head teaching assistant in the Physics and Astronomy Department in August 2019, Lauren Sgro’s life was pretty well mapped out. The Ph.D. candidate had time to work on her dissertation – concerning dust around red dwarfs – while keeping up with head TA duties, such as teaching the new TAs how to do their once-a-week labs and helping anyone with questions. Then the pandemic hit. “After COVID-19, the position…

New materials provide link to innovative products

When we think about the links to the future – the global transition to solar and wind energy, tactile virtual reality or synthetic neurons – there’s no shortage of big ideas. It’s the materials to execute the big ideas – the ability to manufacture the lithium-ion batteries, opto-electronics and hydrogen fuel cells – that stand between concept and reality. Enter two-dimensional materials, the latest step in innovation. Consisting of a single…
