DNA Technique Yields 3-D Crystalline Organization Of Nanoparticles
In an achievement some see as the "holy grail" of nanoscience, researchers have for the first time used DNA to guide the creation of 3-D, ordered, crystalline structures of nanoparticles. The ability to engineer such 3-D structures is essential to producing functional materials that take advantage of the unique properties that may exist at the nanoscale -- for example, enhanced magnetism, improved catalytic activity, or new optical properties.
References To Explicit Substance Use Common In Popular Music
Approximately one-third of popular songs include reference to explicit drug, alcohol or tobacco use, although this portrayal varies widely by musical genre, according to a new report.
Could Statins Prevent Cancer?
A new study evaluates the relationship between statin use and cancer incidence. ACS experts say more research is needed.
Dietary Evidence For Prevention And Treatment Of Cardiovascular Disease
An expert panel examined the state of current research on the effectiveness of foods, nutrients and food components in reducing cardiovascular disease risk factors while also meeting a person's nutrient needs.
Gene Variants Protect Against Adult Depression Triggered By Childhood Stress
Adults who were abused as children have about half the symptoms of moderate to severe depression if they have certain variations in a specific gene, compared to people with different variations in the same gene. The gene makes a receptor, on brain cells, for a stress-related hormone. The variations were protective in two separate studies, one mostly of African Americans and the other of whites, across socioeconomic levels.
