Meteorite mineral named after beer is time capsule Nitrogen in Earth's atmosphere has been traced back to the spinning disc of dust and gas that formed our solar system, and may even have yielded ammonia to fuel organic reactions. This all comes courtesy of a meteorite found in Antarctica named afte...

The fatal attraction of lead For millennia lead has held a deep attraction for painters, builders, chemists and winemakers - but it's done untold harm, especially to children. And while it's no longer found in petrol, you've still got several kilograms of it in your car. Element number 82 is one of a h...

A brief history of timekeeping Caesium is the chemical element that has literally redefined time. All your life you'll have been told the importance of being on time. Well, thanks to caesium the entire world now keeps time so accurately that it has forced us to reconsider what time really is. It has al...

New molecule found in space connotes life origins Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule one with a branched structure contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic hayst...

Diamond crushed to Saturn's extremes Diamond, nature's hardest material, has been crushed to record extremes of pressure using the "world's biggest laser", US scientists report. The carbon crystal was condensed to the core pressure of Saturn - 14 times that at the centre of the Earth....

Mineral hints at bright blue rocks deep in the Earth Minerals preserved in diamond have revealed hints of the bright blue rocks that exist deep within the Earth. They also provide the first direct evidence that there may be as much water trapped in those rocks as there is in all the oceans. The diamond,...

Deposits of Phosphorites Could Be Geological Signpost of Life Two billion years ago, Earth was recovering from a major environmental upheaval that had caused widespread changes in the planets surface conditions. The oxygenation of the atmosphere and oceans had altered global biogeochemical c...

Isotopes are variants of a particular chemical element such that, while all isotopes of a given element have the same number of protons in each atom, they differ in neutron number. Read more The term "isotope" was suggested to Frederick Soddy in 1913 by Margaret Todd, a Scottish physicia...

In 1863 John Newlands noticed that when ordered by weight, every eighth element seemed to share similar properties, such as carbon and silicon in the sequence: carbon, nitrogen, oxygen, fluorine, sodium, magnesium and silicon. He called this a Law of Octaves. Three years later, in 1866, he pre...

Francium is a chemical element with symbol Fr and atomic number 87. It was formerly known as eka-caesium and actinium K. It is one of the two least electronegative elements, the other being caesium, and is the second rarest naturally occurring element (after astatine). Francium is a highly radioac...

August 07, 1869 Charles Augustinus Young and William Harkness (US) independently discover a new bright (emission) line in the spectrum of the Sun's corona, never before observed on earth; they ascribe it to a new element and it is named coronium. In 1941, this green line is identified by Bength Edlé...
