Tip for the Week: Make sure you've scheduled a preconception visit with your ob-gyn to determine risks of genetic diseases and environmental hazards as well as learn about necessary lifestyle changes to ensure a healthy pregnancy and baby. Most important, make sure you've started taking milligrams, or 400 micrograms, of folic acid a day. Folic acid taken a few months before conception has been shown to dramatically reduce such neural tube defects as spina bifida .

Flores is one of many Wallacean islands, which lie east of Wallace's Line and west of Lydekker's Line.  Wallacean islands are interesting because they have rarely, if ever, been connected via land bridges to either the Asian continent to the west or the Greater Australian continent to the east.  This longstanding separation from the surrounding continents has severely limited the ability of animal species to disperse either into or away from the Wallacean islands.  Thus, on Flores there were only a small number of mammal and reptile species during the entire Pleistocene .  These included komodo dragons and other smaller monitor lizards, crocodiles, several species of Stegodon , (an extinct close relative of modern elephants), giant tortoise, and several kinds of small, medium, and large-bodied rats.

Alpha particle emission is modeled as a barrier penetration process. The alpha particle is the nucleus of the helium atom and is the nucleus of highest stability .

While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life , usually given in units of years when discussing dating techniques. After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay product . In many cases, the daughter nuclide itself is radioactive, resulting in a decay chain , eventually ending with the formation of a stable (nonradioactive) daughter nuclide; each step in such a chain is characterized by a distinct half-life. In these cases, usually the half-life of interest in radiometric dating is the longest one in the chain, which is the rate-limiting factor in the ultimate transformation of the radioactive nuclide into its stable daughter. Isotopic systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years (., tritium ) to over 100 billion years (., Samarium-147 ). [4]
