Weather balloon Weather balloon A weather or sounding balloon is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as transosondes. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and
Atelosteogenesis type I Atelosteogenesis type I Atelosteogenesis type I is a rare autosomal dominant condition. This condition is evident at birth and is associated with a very poor prognosis for the baby. It may be diagnosed antenatally. This condition is caused by mutations in the filamin B (FLNB) gene. This gene is located on the short arm of chromosome 3 (3p14). Filamin B forms part of the actin cytoskeleton. How these mutations produce the clinical picture is not yet clear. This is a rare condition with a prevalence of < 1/10. The total number of cases reported to date is <20. Clinical features
