Children who grow up learning to speak two languages are better at switching between tasks than are children who learn to speak only one language, according to a study funded in part by the National Institutes of Health. However, the study also found that bilinguals are slower to acquire vocabulary than are monolinguals, because bilinguals must divide their time between two languages while monolinguals focus on only one.
Nanotechnology, which offers powerful new possibilities for targeted cancer therapies, has been generating a lot of excitement in the cancer research community. Northwestern University scientists recently developed specialized nanoparticle that can deliver a drug directly to a cancer cell’s nucleus — an important feature for effective treatment [1].
Question: I once got a flu shot and then came down with the flu afterward. Now I won’t get the shot anymore. Why did the shot give me the flu?
According to an article in the Morbidity and Mortality Weekly Report, a publication of the U.S. Centers for Disease Control and Prevention (CDC), the prevalence of autism spectrum disorder (ASD) is higher than ever [1]. The CDC periodically surveys the prevalence of ASD, looking during each surveillance period at the percentage of 8-year-old children who have current ASD diagnoses. In 2000, a survey of children born in 1992 revealed that one in 150 had ASD. These numbers have been steadily climbing, such that the most recent survey — completed in 2008 and surveying children born in 2000 — indicates that one in 88 children has ASD. The numbers are even more disturbing for male children, who have an ASD prevalence of one in 54.
This week is National Public Health Week (NPHW). The annual observance brings U.S. communities together to recognize the contributions of public health and highlight issues that are important to improving the public’s health. The theme for National Public Health Week (NPHW) 2012 — A Healthier America Begins Today: Join the Movement — addresses the issue of prevention and wellness.
