(Press-News.org) The University of Tennessee and the UT Institute of Agriculture have received a $434,038 Seeding Solutions grant from the Foundation for Food & Agriculture Research (FFAR) to develop and test a decision support tool for farmers to better manage crop production from risks of extreme weather events across the Tennessee River Basin and surrounding southeast US regions.
UT is providing matching funds for a total investment of $966,119 over the three-year project.
The U.S. Department of Agriculture estimates that extreme weather is responsible for 90% of crop losses. These estimates are generally based on annual climate conditions. However, extreme short-term weather events, termed “flash” droughts and floods, can severely impact crop production. These events have not been researched to the same extent, leading to development of better crop management tools for farmers.
Using novel combinations of watershed hydrology models and monitoring data, including satellites and on-site field monitoring, UT researchers, led by John Schwartz, the director of the Tennessee Water Resources Research Center and professor in the Department of Civil and Environmental Engineering, are developing a decision support tool allowing stakeholders to prepare for unpredictable conditions brought about by flash floods and drought. The collaborative research team includes Ming Jin, director of the Institute for a Secure and Sustainable Environment, and Brian Leib and Shawn Hawkins with the UT Institute of Agriculture.
The researchers are exploring how existing hydrologic and crop models can be combined with historical trends and current monitoring data to inform crop choice, irrigation needs, and farm management. Results are expected to help minimize crop losses and increase yield, maximize water use efficiency, and enhance the resilience of agricultural systems to climate change.
“The decision support tool for row crop producers being developed by our UT research team will provide them useful predictive information,” Schwartz said. “It will be particularly useful for short-term weather hazards, considering in recent years weather patterns in this region have more often shifted to a wetter spring followed by a flash drought early summer, which creates producer challenges of when to plant and whether irrigation is needed.”

Autonomous vehicles can be imperfect — As long as they’re resilient
2024-09-27
Researchers from three of Virginia’s premier universities, including the University of Virginia’s Homa Alemzadeh, aim to take the risk out of self-driving vehicles by overcoming inevitable computer failures with good engineering.
The trio will share a $926,737 National Science Foundation award to identify when and where autonomous vehicle systems are most vulnerable to safety-critical failures. They plan to use this knowledge to design ways to efficiently mitigate potential safety hazards and enhance the overall system resilience.
Alemzadeh, an associate professor of electrical and computer engineering in UVA’s School of Engineering and Applied ...
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
2024-09-27
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimpled surface is covered in impact craters. Scientists have long argued that visible craters on the surface meant that Ceres could not be very icy.
Researchers at Purdue University and the NASA's Jet Propulsion Lab (JPL) now believe Ceres is a very icy ...
McMaster researchers discover what hinders DNA repair in patients with Huntington’s Disease
2024-09-27
Researchers with McMaster University have discovered that the protein mutated in patients with Huntington’s Disease doesn't repair DNA as intended, impacting the ability of brain cells to heal themselves.
The research, published in PNAS on Sept. 27, 2024, found that the huntingtin protein helps create special molecules that are important for fixing DNA damage. These molecules, known as Poly [ADP-ribose] (PAR), gather around damaged DNA and, like a net, pull in all the factors needed for the repair process.
In people with Huntington’s Disease, however, the research found that the mutated version of this protein doesn’t function properly ...
Estrogens play a hidden role in cancers, inhibiting a key immune cell
2024-09-27
DURHAM, N.C. – Estrogens are known to drive tumor growth in breast cancer cells that carry its receptors, but a new study by Duke Cancer Institute researchers unexpectedly finds that estrogens play a role in fueling the growth of breast cancers without the receptors, as well as numerous other cancers.
Appearing Sept. 27 in the journal Science Advances, the researchers describe how estrogens not only decrease the ability of the immune system to attack tumors, but also reduce the effectiveness of immunotherapies that are used to treat many cancers, notably triple-negative breast cancers. Triple-negative ...
A new birthplace for asteroid Ryugu
2024-09-27
In December 2020 the space probe Hayabusa 2 brought samples of asteroid Ryugu back to Earth. Since then, the few grams of material have been through quite a lot. After initial examinations in Japan, some of the tiny, jet-black grains traveled to research facilities around the world. There they were measured, weighed, chemically analyzed and exposed to infrared, X-ray and synchroton radiation, among other things. At the MPS, researchers examine the ratios of certain metal isotopes in the samples, as in the current study. Scientists refer to isotopes as variants of the same element that differ only in the number of neutrons in the nucleus. Investigations ...
How are pronouns processed in the memory-region of our brain?
2024-09-27
A new study shows how individual brain cells in the hippocampus respond to pronouns. “This may help us unravel how we remember what we read.”
Read the following sentence: “Donald Trump and Kamala Harris walked into the bar, she sat down at a table.” We all immediately know that it was Kamala who sat at the table, not Donald. Pronouns like “she” help us to understand language, but pronouns can have multiple meanings. Depending on the context, we understand who the pronoun is referring to. But ...
Researchers synthesize high-energy-density cubic gauche nitrogen at atmospheric pressure
2024-09-27
Recently, a research group led by Prof. WANG Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, successfully synthesized high-energy-density materials cubic gauche nitrogen (cg-N) at atmospheric pressure by treating potassium azide (KN3) using the plasma-enhanced chemical vapour deposition technique (PECVD).
The research results were published in Science Advances.
Cg-N is a pure nitrogen material consisting of nitrogen atoms bonded by N-N single bonds, resembling the structure of diamond. It has attracted attention because it has a high-energy-density and produces only nitrogen gas when it decomposes. ...
Ancient sunken seafloor reveals earth’s deep secrets
2024-09-27
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth’s interior structure. Located in the East Pacific Rise (a tectonic plate boundary on the floor of the southeastern Pacific Ocean), this previously unstudied patch of seafloor sheds new light on the inner workings of our planet and how its surface has changed over millions of years. The team’s findings were published in the journal Science Advances on September 27, 2024.
Led by geology postdoctoral researcher Jingchuan Wang, the team used innovative seismic imaging techniques to ...
