The U.S. Department of Energy has rejected a proposal that would have extended operations at the Paducah Gaseous Diffusion Plant.

For about 60 years, the plant has processed uranium for use in nuclear power plants. Last May, it was scheduled for closure, but a new agreement with the Tennessee Valley Authority and Energy Northwest pushed back the planned shutdown date.

State Rep. Derrick Graham has been named the new chairman of the state House Education committee, Democratic leaders announced today.

The Kentucky Department of Education says many midnight meetings planned at area school districts on June 25 will not place them at the front of the line for a $10,000 grant.

Populations of frogs, salamanders and other amphibians are declining at an average rate of 3.7 percent each year, according to a U.S. Geological Survey study released this week. Researchers say the study is the first to calculate how quickly amphibians are disappearing in the United States.

"If the rate observed is representative and remains unchanged, these species would disappear from half of the habitats they currently occupy in about 20 years," according to the USGS.

Mayor Greg Fischer releases his budget proposal for the next fiscal year, new developments in the Barbara Shanklin removal trial and a senate run for former Miss America Heather French Henry becomes a possibility—these topics and more will be covered today on Byline.

Among voters in the key primary state Iowa, U.S. Sen. Rand Paul is the strongest Republican in the field of prospective 2016  presidential candidates,  says a new poll by Quinnipiac University.

Kentucky's junior senator leads current Vice President Joe Biden by five points among Iowa voters— and he trails former Secretary of State Hillary Clinton, the presumed Democratic frontrunner, by only four points.

Those totals are better than Sen. Marco Rubio, the Floridian who is also a leading Republican contender for the 2016 presidential election.
