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

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 Cambodia’s Central Cardamom Mountains. The Cardamoms are home to most of Cambodia’s large mammals and half of the country’s birds, reptiles and amphibians. Two wildlife sanctuaries border the area, bringing the total land under protection to 2.44 million acres (990,000 hecta

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

An unusual combination of oceanic and atmospheric events may be to blame for a mysterious and sudden die-off of numerous crabs, fish and invertebrate animals off the central Oregon coast during the past two weeks.

Oregon State University researchers who are studying near-shore ecosystems say extremely low oxygen levels – especially in the lower water column – appear to be the culprit.

“Though we are just beginning to amass the evidence, it appears that there has been a confluence o

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
