The Most Excellent Order of the British Empire is an order of chivalry established on 4 June 1917 by George V of the United Kingdom. The Order comprises five classes in civil and military divisions. In descending order of seniority, these are: Only the highest two ranks automatically cause an individual to become a knight or dame, an honour allowing the recipient to use the title "Sir" (male) or "Dame" (female) before their first name (though men can be knighted separately from this and other Orders of Chivalry). Honorary knighthoods, given to individuals who are not nationals of a realm where Queen Elizabeth II is Head of State, permit use of the honour as a post-nominal but not as a title before their name. Awards in the Order of the British Empire in the Commonwealth Realms were discontinued with the establishment of national systems of honours and awards such as the Order of Australia, the Order of Canada and the New Zealand Order of Merit. Foreign recipients are classified as honorary members of the Order they receive, and do not contribute to the numbers restricted to that Order as full members do. There is also a related British Empire Medal, whose recipients are not members

Rice University scientists are developing strategies to keep germs from evolving resistance to antibiotics by heading them off at the pass.
Their pregnancies are carried by the males but, when it comes to breeding, seahorses have more in common with humans than previously thought, new research from the University of Sydney reveals.
Evolutionary biologist Michael Shapiro and his team from the University of Utah made international headlines in 2013 when they found that a prominent change in pigeon plumage, head crests, could be traced to a mutation in ...
An international team of researchers found that the evolutionary loss of the "altruistic" worker caste in ants is not accompanied by a loss of genes.
What makes head lice different from body lice had scientists scratching their heads as previous genetic studies failed to find any substantial differences between the two types of lice.
In butterflies, sex is determined by chromosome differences between males and females. But unlike in humans with the familiar X and Y, in butterflies, it is the females that determine the sex of offspring.
Using sophisticated modeling of genomic data from diverse species, Yale researchers have answered a longstanding question about which competing model of evolution works best.
