The nighttime breathing disorder known as obstructive sleep apnea increases a person’s risk of having a heart attack or dying by 30% over a period of four to five years, according to a new study.

The more severe the sleep apnea at the beginning of the study, the greater the risk of developing heart disease or dying, according to “Obstructive Sleep Apnea is Associated with an Increased Risk of Coronary Artery Disease and Death” (Session B12; Abstract # 1090)presented at the American Thoracic Society 2007 International Conference.

Women who eat apples and fish during pregnancy may reduce the risk of their children developing asthma or allergic disease, suggests a new study presented at the American Thoracic Society 2007 International Conference, on Sunday, May 20.

The SEATON study, conducted at the University of Aberdeen, UK, found that the children of mothers who ate the most apples were less likely to ever have wheezed or have doctor-confirmed asthma at the age of 5 years, compared to children of mothers who had the lowest apple consumption. Children of mothers who ate fish once or more a week were less likely to have had eczema than children of mothers who never ate fish.

A new study finds that the heat setting you choose when doing laundry makes all the difference when it comes to killing dust mites. The researchers found that washing laundry in hot water--140 degrees Fahrenheit (60 ºC) or higher--kills all house dust mites, compared with just 6.5% of dust mites in laundry washed at 104 degrees Fahrenheit (40 ºC), or warm water.

Hotter water temperatures are also more effective in removing dog dander and pollen, says lead researcher Jung-Won Park, M.D., Ph.D., of Yonsei University in Seoul, Korea.

Good news for harried housewives everywhere. Sometimes a house can be too clean. It turns out that kids may need exposure to common bacteria to develop proper immunities.

Endotoxin, a toxic substance made by certain types of bacteria, may reduce the risk of developing the allergic skin condition eczema or wheezing in children if they are exposed to it up to age 3, suggests a study presented at the American Thoracic Society 2007 International Conference, on Sunday, May 20.

Electrical engineers from the University of Delaware and Cambridge NanoTech have demonstrated for the first time how the spin properties of electrons in silicon--the world's most dominant semiconductor, used in electronics ranging from computers to cell phones--can be measured and controlled.

The discovery could dramatically advance the nascent field of spintronics, which focuses on harnessing the magnet-like "spin" property of electrons instead of solely their charge to create exponentially faster, more powerful electronics such as quantum computers.

As societies emerge from conflict, men's dominance at all levels of decision-making ensures women never feel truly secure according to new research funded by the Economic and Social Research Council (ESRC).

In a unique study of women's security and participation in three post conflict societies—Northern Ireland, South Africa and Lebanon—researchers found that women see security differently from men. And because men dominate the institutions of peace-making and peace-building, they often fail to consider the specific security needs of women.
