A group of researchers from the University of Kentucky, The University of Tennessee and Indiana University, including those supported by the U.S. National Science Foundation, have collaborated with scientists from the U.S. Forest Service and others to produce the first complete genome for the white oak (Quercus alba), a tree that provides large amounts of timber and is the primary species used in barrels for aging spirits.

The white oak at Makers Mark Star Hill Farm that provided the sample for recent NSF-funded work to develop a haploid genome for the species, which can be used in conserving this economically important tree.

Data to complete the genome came from a range of academic sources, the Forest Service, state forest services and industry. By combining those data into an unbiased annotation of the white oak’s genes, the researchers have created a resource to understand genetic diversity and population differentiation within the species, assess disease resistance and the evolution of genes that enhance it, and compare with other oak genomes to determine evolutionary relationships between species and how the genomes have evolved.

“Plants, including trees, help meet society’s needs for food, fuel, fiber and, in this case, other key economic services. Having genomic data like this helps us address

Researchers have expanded the potential of carbon capture technology that plucks CO2 directly from the air by demonstrating that there are multiple suitable and abundant materials that can facilitate direct air capture. Researchers present new, lower-cost materials to facilitate moisture-swing to catch and then release CO2 depending on the local air’s moisture content, calling it ‘one of the most promising approaches for CO2 capture.’

WASHINGTON — FEMA announced that federal disaster assistance has been made available to the state of Tennessee to supplement response efforts in the areas affected by severe storms, straight-line winds, tornadoes and flooding beginning on April 2 and continuing.

The President’s action authorizes FEMA to coordinate all disaster relief efforts to alleviate the hardship and suffering caused by the emergency on the local population and to provide appropriate assistance to save lives, to protect property, public health and safety and to lessen or avert the threat of a catastrophe.

The assistance is for all 95 Tennessee counties.

Specifically, FEMA is authorized to identify, mobilize and provide, at its discretion, equipment and resources necessary to alleviate the impacts of the emergency. Emergency protective measures, limited to direct federal assistance, under the public assistance program, will be provided at 75% federal funding.

Darryl L. Dragoo has been named the Federal Coordinating Officer for federal response operations in the affected area.
