They may be exorbitantly expensive at the moment, but cars powered by hydrogen fuel cells have the potential to challenge the dominance of petrol and diesel cars in the near future, said a researcher from Loughborough University in Britain.
In a finding that may have important implications for the evolution of massive stars, a group of researchers presented a model that provides the first characterisation of the progenitor (parent) of a hydrogen-deficient supernova.
Scientists have revealed that astrophysics are still clueless about the quantities of lithium predicted to have resulted from the Big Bang which were not found to be actually present in stars, known as the "lithium problem".
In an impetus for fuel cell technology to build "smart" cars, scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.
Scientists using data gathered by NASA`s Lunar Reconnaissance Orbiter (LRO) mission believe they have solved a mystery from one of the solar system`s coldest regions-a permanently shadowed crater on the moon.
