Turbulence explains the accelerations of an eagle in natural flight.
Proc Natl Acad Sci U S A

Turbulent winds and gusts fluctuate on a wide range of timescales from milliseconds to minutes and longer, a range that overlaps the timescales of avian flight behavior, yet the importance of turbulence to avian behavior is unclear. By combining wind speed data with the measured accelerations of a golden eagle () flying in the wild, we find evidence in favor of a linear relationship between the eagle's accelerations and atmospheric turbulence for timescales between about 1/2 and 10 s. These timescales are comparable to those of typical eagle behaviors, corresponding to between about 1 and 25 wingbeats, and to those of turbulent gusts both larger than the eagle's wingspan and smaller than large-scale atmospheric phenomena such as convection cells.

- Corticosteroid injections into tendon sheaths are common for treating tendon disorders, but there is limited high-level evidence beyond specific conditions like DeQuervain tenosynovitis and trigger finger.
- A systematic review analyzed existing studies on adult tendon sheath injections (excluding the aforementioned conditions), scrutinizing the impact on pain and function while assessing bias.
- The review found 7 articles, all indicating short-term pain relief and some improvement in function, highlighting the need for more controlled studies to verify efficacy.
Objective: This study aimed to identify the Balance Error Scoring System's (BESS) intraclass reliability in a cohort of patients with prolonged symptoms using variance component analysis and intraclass correlation coefficient (ICC).
Setting: Outpatient sports medicine/concussion clinic.
Participants: A total of 241 paediatric and 102 adult patients with symptoms lasting longer than 10 days.
Purpose: To determine the relationship between body mass index (BMI) and fluoroscopy time and radiation dose during fluoroscopy-guided glenohumeral joint injections.
Methods: This was a retrospective analysis of prospectively collected data. Physicians with board certification in Physical Medicine and Rehabilitation and/or Sports Medicine performed or supervised all injections.
Background: Few weight loss interventions are evaluated for longer than a year, and even fewer employ social and mobile technologies commonly used among young adults. We assessed the efficacy of a 2 year, theory-based, weight loss intervention that was remotely and adaptively delivered via integrated user experiences with Facebook, mobile apps, text messaging, emails, a website, and technology-mediated communication with a health coach (the SMART intervention).
Methods: In this parallel-group, randomised, controlled trial, we enrolled overweight or obese college students (aged 18-35 years) from three universities in San Diego, CA, USA.
