The year 2015 has been named the International Year of Light, to mark milestones in the science of light which occurred 1000, 200, 150, 100 and 50 years go. I was a young student in physics in 1965, when the cosmic radiation background was discovered....

Maxwell's electromagnetic theory (now 150 years old) seemed in its comprehensive way to be capable of answering all of the questions one might ever pose about the theory of light. But that spell was broken in 1900 by Planck's discovery that light bea....

In the beginning of the 60s, the laws of classical general relativity, Einstein's generalisation of Newtonian gravity, and of quantum electrodynamics, the quantum version of Maxwell's electromagnetic theory, were known. These laws describe long range....

Molecules to observe and manipulate biological systems can be devised by a variety of strategies, ranging from pure chemical design and total synthesis to genome mining and high-throughput directed evolution. Examples of both successes and failures a....

Ribosomes are the universal cellular machines that act as polymerases that translate the genetic code into proteins. They posses spectacular architecture accompanied by inherent mobility that facilitate their smooth performance in decoding, peptide ....

Within cells or subcellular compartments misfolded and/or short-lived regulatory proteins are degraded by protease machines, cage-forming multi-subunit assemblages. Their proteolytic active sites are sequestered within the particles and located on t....

Within cells or subcellular compartments, mis-folded and/or short-lived regulatory proteins are degraded by protease machines, cage-forming multi-subunit assemblages, the proteasome and HtrA/DegP.  They are essential components in very complex regul....

The founders of quantum theory assumed in 'thought experiments' that they were manipulating isolated quantum systems, obeying the counterintuitive laws which they had just discovered.  Technological advances have recently turned these virtual experi....

How can one advance a working hypothesis that will not be wrong tomorrow and ridiculous the day after? Beyond the Standard Model we find uncertainty and confusion, with both unclarity as to which might be the correct theory, as well as little in the ....

Cold, quantum degenerate gases of neutral atoms have proved to be useful in simulating the behavior of quantum systems like electrons in solids.  For example, cold atoms moving in optical lattices (periodic potentials created by interfering laser be....

Neutrinos have been the origin of an impressive number of ‘surprises’.  We know that neutrinos have tiny masses and that oscillations are occurring spontaneously between neutrino species.  But additional new discoveries may be ahead of us and t....

The strong interactions, the forces responsible for the interactions between quarks and notably supposedly responsible for quark confinement, profited from the development of gauge theories.  In the wake of the gauge theory of weak interactions also....
