Graphene Aerogel – Lightest Material in The World A research team headed by Professor Gao Chao have developed ultra-light aerogel – it breaks the record of the world’s lightest material with surprising flexibility and oil-absorption. This progress is published in the “Research Highlights” column in Nature. Aerogel is the lightest substance recorded by Guinness Book of World Records. NOVA Common House Dust Could Contain Cancer-Causing Molecules For scientists, dust is a goldmine of information about the chemicals we encounter every day. From NOVA Next | Jan 9, 2017 CRISPR and Stem Cells Could Speed Studies of Rare Diseases Too much genetic information can complicate diagnoses for some deadly diseases, but a new technique using CRISPR and stem cells could change that.

Fallacy List 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. A recent study revealed that the number of reported cases of STDs (sexually transmitted diseases) was significantly higher for high schools that offered courses in sex education than for high schools that did not. 2.

Adventure Titles Meet 115, the Newest Element on the Periodic Table If you've learned all the elements from actinium to zirconium, it's time to head back to the periodic table, where there's a new, extremely heavy element in town. The new element doesn't have an official name yet, so scientists are calling it ununpentium, based on the Latin and Greek words for its atomic number, 115. (Related: Read a feature on element hunters in National Geographic magazine.) In case you forgot your high school chemistry, here's a quick refresher: An element's atomic number is the number of protons it contains in its nucleus. The heaviest element in nature is uranium, which has 92 protons.

The Ductile Helix: "Jumping Genes" May Influence Brain Activity Mobile DNA molecules that jump from one location in the genome to another may contribute to neurological diseases and could have subtle influences on normal brain function and behavior, according to a study published October 30 in Nature. (Scientific American is part of Nature Publishing Group.) Retrotransposons are mobile genetic elements that use a copy-and-paste mechanism to insert extra copies of themselves throughout the genome. First discovered in plants about 60 years ago, they are now known to make up more than 40 percent of the entire human genome and may play an important role in genome evolution (pdf).

Brilliant: Mandelbrot Set The term Mandelbrot set is used to refer both to a general class of fractal sets and to a particular instance of such a set. In general, a Mandelbrot set marks the set of points in the complex plane such that the corresponding Julia set is connected and not computable. "The" Mandelbrot set is the set obtained from the quadratic recurrence equation with , where points
