The recent discovery of water on the Moon may have a serious impact on future plans for lunar based astronomy.  Space scientists from the Chinese Academy of Sciences have calculated that the scattering caused by molecules vaporized in sunlight could heavily distort observations from telescopes mounted on the Moon. "Last year, scientists discovered a fine dew of water covering the Moon. This water vaporizes in sunlight and is then broken down by ultraviolet radiation, forming hydrogen and...

MIT and Boston University researchers have discovered that the drug hydroxyurea kills bacteria by inducing them to produce molecules toxic to themselves "” a conclusion that raises the possibility of finding new antibiotics that use similar mechanisms. Hydroxyurea inhibits the enzyme critical for making the building blocks for DNA, so for decades it has been used to study the consequences of inhibiting DNA replication in E. coli, yeast and mammalian cells. It is also sometimes used in...

In a discovery that promises to reinvigorate studies of the moon and potentially upend thinking of how it originated, scientists at Brown University and other research institutions have found evidence of water molecules on the surface of the moon. The molecules and hydroxyl "” a molecule consisting of one oxygen atom and one hydrogen atom "” were discovered across the entire surface of earth's nearest celestial neighbor. While the abundances are not precisely known, as much as...

Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere.Hydroxyl, an important but difficult-to-detect molecule, is made up of a hydrogen and oxygen atom each. It has been found in the upper reaches of the Venusian atmosphere, some 100 km above the surface, by Venus Express's Visible and Infrared Thermal Imaging Spectrometer, VIRTIS.The elusive molecule was...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
