Exercise in cold water instead of warm water may increase peoples appetites, making it harder for them to lose extra pounds, a University of Florida study finds.
Results indicate people may consume more calories after exercising in cold water, according to Lesley White, a UF researcher who designed the study to better understand why aquatic exercise is often less successful than equal amounts of jogging or cycling for people who want to lose weight. "Its possible that individuals who exercise in cooler water may have an exaggerated energy intake following exercise, which may be a reason why they dont lose as much weight," said White, an assistant professor in the College of Health and Human Performance. "So it may not be the exercise itself that causes the problem because you can match the exercise energy expenditure; rather its the increased eating after the exercise is over."
White said her research is not meant to suggest that swimming or aquatic exercise is ineffective for building physical fitness. In fact, water exercise is suggested for people who are overweight because the buoyancy given by the water makes exercising easier for people with joint or balance problems. "Water exercise is an excellent activity for many people, particularly those with joint disorders, thermal regulatory problems and balance or coordination difficulties," she said. "However, an earlier study reported that women who swam did not lose as much weight as those who jogged or cycled."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
