Beginning the week of Sept. 22 and running through mid-November, the city of Boulder will be making improvements to the medians on Broadway between College Avenue and Marine Street. These improvements will include installing new irrigation piping, planting new vegetation and repairing some concrete components of the medians.

During this period, there may be one-lane closures on Broadway to accommodate the crews and their equipment. Closures will be limited to Monday through Friday, 8 a.m. to 3 or 4 p.m. The city will do everything possible to have both northbound lanes open for the morning commute and both southbound lanes open for the evening commute.

Do you have trouble falling asleep before 1 a.m.? Do you find it difficult to wake up early in the morning for your commitments? Does your high schooler have a hard time falling asleep before 1 a.m. and waking up early in the morning/for high school?

The study is 6.5 weeks long with six in-person visits and will include:

• Health screening
• Monitor on separate occasions your sleep, mood, eating times for one or two weeks and blood sugar levels while living at home
• Live in the sleep laboratory on two separate occasions for 48-66 hours (approximately 4.87 days in total):

The study is seven weeks long with eight in-person visits at CU Boulder. Participants live in the sleep laboratory on two separate occasions for 7.7 days (15.4 days total).

Compensation is up to $4,093.

Twenty new outdoor warning sirens have been installed across Boulder County and county officials will run a systemwide test at 10 a.m. on Friday, Sept. 19.

The test will last approximately three minutes. During this time, residents will hear:

• Five short beeps.
• A voice message stating, “This is a test.”
• A siren tone.
• A closing voice message repeating, “This is a test.”

This test is the final part of the installation process to ensure the upgraded sirens are operating properly and ready to alert the community in the event of an emergency.

The federal government is introducing enhanced research security training requirements for key personnel associated with federal grants. Enhanced requirements for NSF and USDA submissions go into effect starting on Oct. 1, 2025. Enhanced requirements for DOE submissions went into effect on May 1.

As part of the revised academic calendar, Thursday, Oct. 9, is designated as a fall mid-semester reading day—a time for students to reflect, review and prepare for the remainder of the semester. No classes or exams should be held. Athletic events and academically scheduled student events (e.g., concerts, performances) may proceed as scheduled.

Colorado Law, however, follows a different academic calendar. All Colorado Law classes (LAWS 5000 level and above) will be held as usual on Oct. 9.

Friday, Oct. 10, is a regular class day. Faculty are encouraged not to cancel classes or reschedule exams or assignments in anticipation of potentially low attendance ahead of the home football game on Saturday, Oct. 11.

Students are encouraged to honor the intent of the reading day by using the time well and making responsible choices as the weekend begins.
