Without adequate cleaning regimes swimming pools can become a health hazard.
Now water experts and mathematicians are ‘pooling’ their expertise to anticipate the factors that lead to an unhealthy swimming environment.
The researchers are testing different water treatments using a unique pilot pool, donated by an advisory body, that simulates the chemical environment of a municipal swimming pool. Significantly this research technique could also be applied to other water recycling systems,
Fruit rinds provide new clues about crop domestication
Distinctly sculptured opaline phytoliths in soil and plant remains tell archaeologists which plants were present thousands of years ago. However, the production and purpose of these tiny glassy structures common in plant tissues is poorly understood. Dolores Piperno at the Smithsonian Tropical Research Institute (STRI) in Panama and colleagues predict that a single genetic locus controls both lignin and phytolith production in sq
Researchers studying global warming have often been confounded by the differences between observed increases in surface-level temperatures and unchanging low-atmosphere temperatures. Because of this discrepancy, some have argued that global warming is unproven, suggesting instead that true warming should show uniformly elevated temperatures from the surface through the atmosphere. Researchers have proposed a theory that changes in cloud cover could help explain the puzzling phenomenon, but none-until
Cardamom Mountains former home to Khmer Rouge
The Cambodian government announced today the creation of the Central Cardamoms Protected Forest, a 1,000,000-acre (402,000-hectare) area in southwestern Cambodias Central Cardamom Mountains. The Cardamoms are home to most of Cambodias large mammals and half of the countrys birds, reptiles and amphibians. Two wildlife sanctuaries border the area, bringing the total land under protection to 2.44 million acres (990,000 hecta
Male patients who suffer from obstructive sleep apnea (OSA) — the inability to breathe properly during sleep — produce lower levels of testosterone, resulting in decreased libido and sexual activity, according to researchers at the Technion-Israel Institute of Technology. Previous studies had indicated that male sleep apnea patients had reported decreased libidos but the studies were unable to establish a scientific link. The current study, reported in the July issue of The Journal of Clinical End
By the time you`ve had your new computer for six months, much faster processors will already be on the market. But there is a limit to how fast conventional computers can become. This is because computers process information in a step-by-step fashion, carrying out each part of the process in turn. To make things work really fast, we need to build `quantum computers` instead. Computers today handle information in binary form, representing everything as zeros or ones. In order to process that
