On the first day of the New York Fashion Week, one model in particular captured the attention and applause of the audience.

A Jet plane in flight creates rapidly spiraling swirls of air at the tips of its wings. These vortices cause drag, increasing fuel consumption. They also buffet planes that may be following closely. Thus, flights departing from the same runway must be sufficiently spaced to allow time for the vortices to dissipate.

Despite medical advances, disease continues to plague mankind. Yet, as evidence shows, many health problems are preventable. World The World Health Organization predicts that 24 million people will be diagnosed with cancer annually by 2035. This is an increase of about 70 percent more than the number currently diagnosed, which is thought to be over 14 million. An estimated half of those cases will be caused by lifestyle factors, such as alcohol abuse, inactivity, obesity, radiation exposure, and smoking.

Although the earth produces clean air, nourishing food, and fresh water, humans are increasingly disrupting these natural processes. Scientists are desperately seeking solutions to reverse this trend.

Like barnacles, marine mussels attach themselves to rocks, wood, or ship hulls. However, unlike barnacles, which fasten themselves tightly to a surface, marine mussels dangle by a network of thin filaments called byssus threads. While this method increases the mussel’s flexibility for feeding and migration, the threads seem too flimsy to withstand the impact of ocean waves. How does the byssus allow the mussel to hang on and not be swept out to sea?

IGNAZ SEMMELWEIS may not be a household name, yet his work has benefited most modern families. Born in Buda (now Budapest), Hungary, he received his medical degree at the University of Vienna in 1844. On taking up his post as assistant to a professor at the First Maternity Clinic of Vienna’s General Hospital in 1846, Semmelweis faced an appalling reality —more than 13 percent of the women giving birth there died from a disease called childbed fever. Various theories as to the cause of this disease had been proposed, yet no one had solved the mystery. All attempts to reduce the mortality rate proved futile. Troubled by the spectacle of numerous mothers suffering a slow, agonizing death, Semmelweis determined to find the cause of the disease and prevent it.
