From various independent observations, cosmologists have established that ordinary matter, made of protons and neutrons, accounts for only 4% of the total energy content of the Universe. The remaining 96% is made of puzzling ingredients Dark Matter and Dark Energy. Researchers at the Laboratory Universe and Theories from the Observatory of Paris and the Belgian Fonds de la Recherche Scientifique have recently suggested the Abnormally Weighting Energy (AWE) Hypothesis to describe the dark side of the Universe as a revolutionary aspect of gravitational physics.

A new study has found that risks from radiation exposure to people involved in the Chernobyl incident may be much less significant than most of us think.

Significant gains can be made in efforts to combat global warming by reducing energy use and improving energy efficiency in buildings, says a new report from the United Nations Environment Programme (UNEP) Sustainable Construction and Building Initiative (SBCI).
