Helium production and storage in the United States, 1940-2014 (data from USGS) In 1903, an oil exploration well at Dexter, Kansas, produced a gas that would not burn.. Kansas state geologist Erasmus Haworth took samples of the gas back to the University of Kansas at Lawrence where chemists Hamilton Cady and David McFarland discovered that gas contained 1.84 percent

These fields contain natural gas with unusually high percentages of helium—from 0.3% to 2.7%—and constitute the United States' largest helium source. The helium is separated as a byproduct from the produced natural gas. After the Helium Acts Amendments of 1960 (Public Law 86–666), the U.S. Bureau of Mines arranged for five private plants ...
Around this time, it was discovered that helium enabled divers to stay under water longer and ascend in a shorter time, presenting another application for helium. In reaction to depleting helium sources, the Helium Act of March 3, 1927 was established to prohibit the sale of helium to foreign countries and for non-governmental domestic use. [8]
Fire officials in Los Angeles have run into a serious snag while trying to contain the nearly half-dozen blazes threatening the city - questions about the water supply.. Wildfires currently cover ...
The helium atom has vibrations in the ultraviolet range, which is strongly absorbed by the atmospheres of the outer planets and Earth. Thus, despite its abundance, helium was only detected once spacecraft were sent to the outer planets, and then only indirectly through collision-induced absorption in hydrogen molecules.

The fair is fed by 28 regional science fairs, each of which is allocated a number of projects based on prior history of producing winning entries. The allocation in 2009 was 908 projects, an average of 24.7 projects per million population. [1] Awards are given in several categories at both junior (grades 6–8) and senior (grades 8–12) levels.
