Researchers Consider Possible Mechanistic Links Between Obesity And As
Reports have shown that nearly 75 percent of emergency room visits for asthma have been among obese individuals and studies have shown that obesity pre-dates asthma. The risk for developing asthma increases with increasing obesity among individuals. Yet little is known about how obesity influences asthma. Today in History: July 4
A brief history of the holiday also known as Independence Day, which observes the day in 1776 when "the Second Continental Congress unanimously adopted the Declaration of Independence."Includes speeches, music, photos, and links to related topics.

Mayo Clinic physicians have adapted real-time 3-D ultrasound imaging devices -- including one designed to look at an infant's heart -- so that they can watch as they use a needle filled with anesthetic to numb individual nerves located inches under the skin. In this way, they can quickly block nerve function in selected areas of the body prior to surgery, an advance that may spare patients from use of general anesthesia, and sends them home faster and with less need for pain medication. Preposterous Headdresses and Feathered Ladies: Hair, Wigs, Barbers, an
This companion to a 2003 exhibit at the Yale University's Lewis Walpole Library features "a selection of prints [from the second half of the 18th century] focused on hair and wigs, and on the hairdressers and barbers who created and tended them."Includes images of prints such as "A Doleful Disaster, or Miss Fubby Fatarmin's Wig Caught Fire"and "A French Hair Dresser Running through the Streets to his Customers." Eye Condition, If Left Untreated In Children, May Result In Permanent
When a child is farsighted or has astigmatism or has both conditions in both eyes, bilateral amblyopia may develop. In contrast to single-eye amblyopia or "lazy eye,"bilateral amblyopia affects both eyes and is less common. In a new article, researchers report that this condition can be successfully treated with corrective lenses, particularly when diagnosed and treated early. Left untreated, bilateral amblyopia may result in permanent visual disability. Earth Systems Research Laboratory, Global Monitoring Division: South P
Website for the South Pole Observatory (SPO), which was "established at the geographical south pole at 2837 m above sea level in 1957 as part of the International Geophysical Year."Features live views of the South Pole, current weather, background about South Pole scientific facilities, material about the ozone hole, photos and time-lapse movies, and links to related websites.

Scientists show that genetic variation in the foraging gene results in different tolerance for heat stress and demonstrate how the use of specific drugs can replicate this effect in fruit flies and locusts. While the findings are at an early stage, the researchers suggest that they could lead to ways to rapidly protect the brain from extremely high fevers in mammals, including humans. 'Pony Express' Protein Shown To Rally Biological Clock
A biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily over a 24-hour period. Auto Immune Response Creates Barrier To Fertility; Could Be A Step In
Plant biologists have discovered that an autoimmune response, triggered by a small number of genes, can be a barrier to producing a viable offspring. This could be a newly identified step toward speciation. This finding presents a new theory in the development of new species: two plants of the same species fail to reproduce not because of infestation or infection from an outside organism, nor from problems with reproductive organs. The biologist suggested that the necrotic plant is possibly analogous to a fertilized egg that fails to implant in the uterus. Infertility in couples might be explained by analogous auto-immune genetic profile. "How many couples can't produce progeny, but when they separate and find another mate, they do?" Fever After Smallpox Vaccination Tied To Individual Genetic Variations
Researchers have identified common DNA variations that underlie susceptibility to fever after smallpox vaccination. Their finding is the first to link individual differences written into the genetic code with a vaccine-related complication -- albeit a mild one.
