Larry Lee, an assistant professor of Experimental High Energy Particle Physics at the University of Tennessee, has been named a Cottrell Scholar.

A new study published in the journal Science Advances by an international team of climate scientists presents the first realistic supercomputer simulation that resolves the complex interactions between fire, vegetation, smoke and the atmosphere. The authors find that increasing greenhouse gas emissions will likely increase the global lightning frequency by about 1.6% per degree Celsius global warming, with regional hotspots in the eastern United States, Kenya, Uganda and Argentina [Figure 1A]. Locally this could intensify wildfire occurrences. However, the dominant drivers for the growing area burned by fires each year [Figure 1B] remain shifts in global humidity and a more rapid growth of vegetation, which can serve as wildfire fuel.

NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s deployable aperture cover — a visor-like sunshade that will help prevent unwanted light from entering the telescope — to the outer barrel assembly, another structure designed to shield the telescope from stray light in addition to keeping it at a stable temperature.

Our cells constantly receive DNA damage from factors such as ultraviolet rays, irradiations, toxins and chemicals. For women, that can lead to poor egg quality, which in turn can cause infertility, miscarriage, birth defects or genetic disorders.

Researchers at the University of Missouri are now working to better understand a process that can help repair that damage.
