The idea that your bladder shrinks as you get older may be nothing more than an old wives tale according to a University of Pittsburgh study. The feeling may, however, signal a treatable underlying condition. Results are to be presented today at the annual meeting of the American Urological Association (AUA) in San Antonio, and will be published in abstract 1218 in the AUA proceedings.
"Many of us, after reaching a certain age, notice that we have to urinate more frequently and with more urgency. The standard assumption, that seems to have become part of our folklore, is that your bladder shrinks as you get older. We found that this may not be the case," said Neil Resnick, M.D., professor and chief, division of geriatric medicine, University of Pittsburgh School of Medicine.
In the study, the researchers compared data on a number of variables including bladder capacity and stability, urethral closure pressure, voiding flow rate and detrusor contraction strength from 95 females between the ages of 22 and 90. The researchers found that while bladder and urethral function deteriorate throughout adult life, bladder capacity rarely changes.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
