|  The entropy of nations: Global energy inequality lessens, but for how long?  | Inequality in the way nations consume energy has been lessening in recent years. An underlying thermodynamic process seems to be at work. | Read More » Electronic tongues measure grape ripeness  | Electronic tongues can become an ally of grape growers as they offer detailed information on the degree of grape maturity and this could improve competitiveness. | Read More » Environment affects an organism's complexity  | Scientists have demonstrated that organisms with greater complexity are more likely to evolve in complex environments. | Read More » How invariant natural killers keep tuberculosis in check  | Mycobacterium tuberculosis is a major cause of death worldwide, and a formidable foe. Most healthy people can defend themselves against tuberculosis, but they need all parts of their immune system to work together. A new study reveals how a special class of immune cells called "invariant natural killer T cells" make their contribution to this concerted effort. | Read More » Another step towards understanding the quantum behavior of cold atoms  | Physicists have explored, on a theoretical level, some quantum effects that take place in atoms at a very low temperature. Firstly, he has discovered that boson-type atoms and fermion-type ones can be mixed in a specific way. So he has made the necessary conditions for carrying out these experiments available to experimental physicists. Secondly, he has deduced how fermions would influence bosons in this case. | Read More » | |
