Unraveling RNA\u2019s Secrets<\/h2>\n\n\n\n
Despite RNA’s starring role in COVID-19 vaccine development, scientists are still unlocking the molecule\u2019s secrets. Better understanding how RNA contributes to cell function and gene expression could lead to treatments for a variety of ailments, including cancer, macular degeneration, high cholesterol, pain and organ diseases.<\/p>\n\n\n\n
With a $1 million CAREER award, Nebraska\u2019s Catherine Eichhorn, assistant professor of chemistry, is investigating relationships between the structures and functions of RNA-protein complexes, called ribonucleoproteins, or RNPs.<\/p>\n\n\n\n
She\u2019s focusing on an RNP known as 7SK, a key player in gene expression. Eichhorn uses powerful imaging techniques to develop high-resolution images of 7SK\u2019s structures and folding dynamics. The images help reveal how 7SK regulates activity within cells.<\/p>\n\n\n\n
Her methods and discoveries may also lead to a deeper general understanding of RNA and RNPs.<\/p>\n\n\n\n
Eichhorn is launching a laboratory to guide students through an innovative imaging technique that links a fluorescent molecule to 7SK in order to track its behavior inside living cells. The technique will give students the opportunity to develop and test hypotheses.<\/p>\n\n\n\n

That is, he studies singularities, points at which geometrical shapes don\u2019t behave well.<\/p>\n\n\n\n Jeffries, assistant professor of mathematics, received the mathematics department\u2019s first CAREER award. He\u2019ll use the $400,000 grant to advance his research in commutative algebra, a field of abstract algebra that focuses on polynomials, algebraic expressions with many variables.<\/p>\n\n\n\n \u201cSystems of polynomial equations are ubiquitous throughout the sciences,\u201d Jeffries said. \u201cSingular points are of interest because many standard techniques and algorithms can go haywire at those points.\u201d<\/p>\n\n\n\n He\u2019s also studying polynomial equations and singularities within atypical number systems. For example, computer data and arithmetic are built on systems of two numbers: zero and one. He aims to develop new tools to study the small-scale behavior of systems of polynomial equations of both familiar number systems and these atypical systems.<\/p>\n\n\n\n To encourage high school students to study mathematics, Jeffries is launching a math circle in which a mathematician leads students through an advanced math activity. At least one session per semester will be conducted in Spanish.<\/p>\n\n\n\n Nebraska is one of the nation\u2019s largest research clusters in commutative algebra and algebraic geometry and an international leader in these fields.<\/p>\n\n\n\n Nebraska news release: Jeffries’ CAREER award bolsters Nebraska’s mathematics expertise<\/a><\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n While drones can perform an impressive array of tasks, they can\u2019t think for themselves.<\/p>\n\n\n\n Nebraska’s Justin Bradley, associate professor of computer science and engineering, is changing that with a nearly $500,000 CAREER award.<\/p>\n\n\n\n Bradley aims to give drones and other robots the ability to self-adapt to a changing environment. He\u2019s developing mathematical and computing foundations, analytical tools and algorithms that divert energy to important tasks while pausing lower-priority work.<\/p>\n\n\n\n The ability to allocate resources and optimize overall performance will help maximize the full potential of artificial intelligence and machine learning. Because AI consumes substantial resources, robots must be able to give and take computational power to AI to accomplish a range of tasks.<\/p>\n\n\n\n Ultimately, Bradley will create an autopilot system compatible with the widely used Robot Operating System and operable on common robotics hardware. He’s seeking a provisional patent.<\/p>\n\n\n\n “This will be really useful for future missions that are complex and changing,” Bradley said. \u201cThis will allow robotic aircraft to do longer and more efficient surveillance and reconnaissance missions where the environment is changing.”<\/p>\n<\/div><\/div>\n\n\n\n Nebraska news release: Bradley’s CAREER project to boost drones’ adaptability, performance<\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n Improving 3D molecular structures could aid advancements in electronics, medicine and more.<\/p>\n\n\n\n With a nearly $600,000 CAREER award, Siamak Nejati, assistant professor of chemical and biomolecular engineering, is developing an environmentally friendly and highly precise method of creating porous organic frameworks, versatile 3D structures made of light elements, such as carbon, nitrogen and oxygen.<\/p>\n\n\n\n He\u2019s using a molecular layer deposition process that doesn\u2019t require solvents to construct ultrathin, nanoporous films that feature a diverse and adjustable range of porosity. Porosity allows materials to trap, separate or filter.<\/p>\n\n\n\n By honing a vapor-phase approach, Nejati aims to enable integrating the films into energy-efficient, highly selective filters for gas and liquid separation as well as electrodes for energy conversion and storage devices.<\/p>\n\n\n\n Moreover, the proposed research pathway allows for studying the physical and chemical properties of the frameworks, essential for developing fabrication processes with low environmental impact and energy footprints.<\/p>\n<\/div><\/div>\n\n\n\n Nebraska news release: Nejati’s molecular research earns CAREER award<\/a><\/p>\n<\/div>\n\n\n\n With a nearly $700,000 CAREER award, Nebraska geochemist Lynne Elkins is developing a tool to help illuminate processes governing volcanoes, particularly magma, the molten rock that erupts from deep within the Earth as lava.<\/p>\n\n\n\n Elkins is producing a publicly available, open-source computer modeling program that calculates the expected compositions of magmas, which result from partial melting of the Earth\u2019s mantle layer. The models focus on predicting trace quantities of uranium-series isotopes in lavas. This type of geochemistry measurement traces the nature and timing of Earth\u2019s melting processes.<\/p>\n\n\n\n A more comprehensive understanding of these processes will provide important clues about how magma generation is linked to plate tectonics, how the Earth\u2019s crust formed and, more generally, how the natural world works.<\/p>\n\n\n\n The tool also may advance a longstanding debate about the types of mantle rocks that melt to generate most magma.<\/p>\n\n\n\n \u201cThe fundamental question here is: How does the planet function?\u201d said Elkins, assistant professor of earth and atmospheric sciences. \u201cDeveloping better tools with computer coding makes the answers to this question more accessible to the broader scientific community.\u201d<\/p>\n<\/div><\/div>\n\n\n\n Nebraska news release: Elkins developing modeling tool to shed light on makeup, movement of magma<\/a><\/p>\n<\/div>\n\n\n\n With support from the National Science Foundation\u2019s Faculty EarlyCareer Development Program, Nebraska researchers are unlockingRNA\u2019s mysteries, advancing commutative algebra, improving drone performance, revolutionizing nanomaterials and studying magma\u2019s composition. In 2021, five outstanding pre-tenure faculty members earned these prestigious awards, totaling $3.2 million. Background photo by Volodymyr Tverdokhlib\/Shutterstock.
