While most scientists believe that allergies cause asthma, researchers at Washington University School of Medicine in St. Louis are uncovering a second potential cause for this common respiratory illness. Their new model suggests that a viral infection in the first years of life may leave a lasting mark on the immune system, causing chronic respiratory problems later on. “While the allergic response may increase during an asthma attack, our research suggests that the anti-viral response also

Field Museum scientists describe “loop and pull” in Nature Snakes are known to swallow their prey whole, which limits the size of what they can eat. But now scientists have discovered that a species of snake can tear apart its prey. This snake loops its body around a crab to hold one end while using its mouth to pull off legs or rip the crab’s body into pieces. This “loop and pull” method allows a snake to eat crabs that are relatively huge – far too large to swallow whol

Patients with osteoarthritis of the knee who underwent placebo arthroscopic surgery were just as likely to report pain relief as those who received the real procedure, according to a Department of Veterans Affairs (VA) and Baylor College of Medicine study published in the July 11 New England Journal of Medicine. The researchers say their results challenge the usefulness of one of the most common surgical procedures performed for osteoarthritis of the knee. “The fact that the effecti

Interrupting anti-HIV treatment for an extended period and then re-initiating therapy might be safe in some patients, according to a study by Northwestern University infectious disease experts. Chad Achenbach, M.D., and co-investigators from The Feinberg School of Medicine presented data from their research today at the XIV International AIDS Conference. In an observational study, 25 HIV-infected patients with viral suppression for at least six months while receiving highly active a

Smokers who inherit a particular genetic trait could triple their chances of getting lung cancer according to a report in the British Journal of Cancer.* While tobacco is the biggest cause of lung cancer. the risk of developing it varies. This has led scientists to believe that genetics may have a crucial role in deciding who is most susceptible to the disease. German researchers have found that a quarter of patients with the most common form of lung cancer carry a particular version of a g

The Brazilian World Cup celebrations may have started to die down, but in space the never-ending football match between the Sun and Earth continues. And watching this match closely are Salsa, Samba, Rumba and Tango, the four satellites that make up the Cluster mission. They are performing their Brazilian dances 119 000 kilometres above our heads. With all the grace and skill of the Brazilian players on the football field, the spacecraft making up the Cluster quartet are currently chan
