Had shoulder replacement surgery? Help us learn how long implants last and how well they work over time. We're tracking patients with shoulder replacements to better understand results years after surgery. Your experience can improve care for future patients.

This study explores how parenting behaviors and early-life stress may shape a child's brain and behavior. We are inviting parents of children aged 0-5 to share information through a short survey. Some families may be invited to try out a new early learning toolkit designed to support their child's development.

We're testing a new blood test called Multi-Cancer Detection (MCD). This test looks for signs of many types of cancer. We want to learn if it can find cancer early when treatment might work better. Your participation could make a big difference. Thank you for considering joining us!

Do you have pain at the front of your knee? Does this pain get worse with using stairs, running, jumping, or prolonged sitting? Do you participate in any type/level of sport? Then we want to hear from you!! We are conducting a fully online survey study to understand what influences physical activity levels in athletes with anterior knee pain (pain at the front of your knee). If you complete all 7 surveys you will be entered to win one of five $50 Amazon gift cards.

In this study, we're interested in understanding couples' experiences with using ChatGPT and each other for emotional support. We are recruiting couples to take part in a paid virtual study! This study includes 21 days of short online surveys sent via email, and you can earn up to $34 each for your participation.

We are creating a new way to understand online sexual harassment. As technology changes, people find new ways to harm others online. Current tools don't catch all these new types of harassment.

Would you like to learn more about your body composition and resting metabolic rate? If you identify as Asian and are between 18-35 years old, you may be eligible to participate in a research study evaluating body composition and metabolic health in multiple Asian ethnicities.

We are conducting two 3 hour in-person workshops with young adults who consume alcohol to support the development of an intervention which uses social medial to address the link between alcohol use and cancer risk.

Spectra Discovery is a research study looking to see if wearable devices can measure screen time use in children ages 3 to 8. Your child will wear fake glasses and a shirt clip with light sensors to track light from screens. They will also wear an activity counter around their waist to track movement. During the study, your child will use a study-provided Android tablet, which includes an app to track screen use. The study lasts one week and includes: a baseline survey, daily time-use surveys, device logs at the end of each day, and a follow-up survey. To get started, parents will complete an online baseline survey and schedule an in-person orientation, either at home or at our Chapel Hill office. Families will be compensated for their time, and children will receive a thank-you gift. This study helps us learn if these wearable devices can measure screen use in young children.

Preventing walking disability in our rapidly aging population is an enormous public health challenge. Fundamental to their loss of functional mobility is that the muscles needed to power walking experience decline in function with age. Wearable assistive devices can be designed to augment the function of these muscles and may make walking easier. If you are a healthy older adult, you may be able to participate in a training intervention to determine the feasibility of a passive wearable ankle device that strengthens walking dynamics and decreases fall risk.
