Jim al-Khalili: Beyond the Standard Model
Experiments at Cern will tackle a dilemma at the heart of modern physics that defeated even Einstein, says Jim al-Khalili
Simon Singh: Welcome to the particle menagerie
Up, down, top, bottom, charm, strange, axions, sleptons and quarks. How do physicists dream up such whimsical names for the fundamental particles they discover? Simon Singh explains
Lawrence Krauss: Worth every penny
Building the LHC has cost the world's taxpayers more than £5bn so far. Lawrence Krauss explains why understanding particle collisions is, like great art, music or literature, a vital part...
Meet Peter Higgs, father of the 'God Particle'
To many people, the sole purpose of the LHC is to find the famous Higgs boson. James Randerson met the self-effacing man behind the legend
New Efficiency Benchmark For Dye-sensitized Solar Cells
Scientists have achieved a record light conversion efficiency of 8.2 percent in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it...
Scientists: Nothing to Fear From Atom-smasher
Collider won't destroy world when goes online in August, scientists say.
Ethanol Coproducts Eyed As Fillers In Plastics
A coproduct of ethanol production could be used as a non-petroleum-based filler in plastics, based on preliminary studies by Agricultural Research Service (ARS) scientists and their cooperators. The ethanol coproduct,...
Tick And Mosquito Repellent Can Be Made Commercially From Pine Oil
A naturally-occurring compound prepared from pine oil that seems to deter mosquito biting and repels two kinds of ticks has been developed. This newly-discovered repellent can be prepared inexpensively from...
Citing Need for Assessments, U.S. Freezes Solar Energy Projects
The freeze has caused widespread concern in the industry, forcing fledgling solar companies to wait just as demand for alternative energy is accelerating.
