Knox County school board members are asking Superintendent Bob Thomas to provide details about what data the district will use to decide when students will no longer be required to wear masks to help prevent the spread of COVID-19.
Board policy requires students and staff to wear a mask in most settings, with some exemptions for activities like eating or drinking during lunch time. The policy is in effect until board members amend it or vote to end it.
Board members are considering establishing a sunset clause for Aug. 1, meaning the policy would automatically end on that date. The suggested revision to the policy would also mean the board could renew the policy on a month-to-month basis if circumstances change. The board will vote on the policy revision next Wednesday.
How fast is the universe expanding

Despite a century of measurements, astronomers can’t agree on the rate at which the universe is expanding.
A technique that relies on measuring distances to a specific type of aging star in other galaxies called the J-region Asymptotic Giant Branch, or JAGB method might be able to help.
Astrophysicist and University of Chicago graduate student Abigail Lee is the lead author on a new paper that analyzed observations of light from a nearby galaxy to validate the JAGB method for measuring cosmological distances.
This novel technique will allow future independent distance measurements that can help answer one of the biggest outstanding questions in cosmology: how fast is the universe expanding?
