Filligent, a Hong Kong-based biotech company, is mobilizing stocks of its anti-infective BioMask to help combat the global spread of the deadly new Mexican strain of Influenza A.   The BioMask is the first medical face mask to kill the Influenza A virus within seconds of contact while retaining the breathability required by front-line workers and children, who are often the first to fall in a contagious episode.

The idea that far distant particles can somehow 'talk' to each other led Einstein to call it 'spooky action at a distance'.

Having confirmed its existence, scientists today are learning how to use this 'spooky action' as a helpful tool. Now a team of physicists at the University of Bristol and Imperial College London have harnessed this phenomenon to shed light on another unusual and previously difficult aspect of quantum physics - that of distinguishing between two similar quantum devices.

In the everyday world any process can be considered as a black box device with an input and an output; if you wish to identify the device you simply apply inputs, measure the outputs and determine what must have happened in between.

Scientists of Helmholtz Zentrum München, led by Professor Martin Hrabé de Angelis, director of the Institute of Experimental Genetics, have developed a new mouse model with a genetic mutant in which a single base of a specific microRNA seed region has been altered. Mice carrying this miR-96 mutation suffer progressive hearing loss as they get older.    Moreover, if they carry two of these mutants, their sensory hair cells are impaired from birth on.

The theory that the Chicxulub crater holds the clue to the demise of the dinosaurs and 40 percent of all species 65 million years ago is challenged in a paper published in the Journal of the Geological Society.  The Chicxulub crater, discovered in 1978 in northern Yucutan and measuring about 112 miles in diameter, lies under a km of debris and records a massive extra-terrestrial impact by an object 10-20 km in size.

On April 21, 2009, CDC reported that two recent cases of febrile respiratory illness in children in southern California had been caused by infection with genetically similar swine influenza A (H1N1) viruses. The swine flu viruses contained a unique combination of gene segments that had not been reported previously among swine or human influenza viruses in the United States or elsewhere (1).

Neither child had known contact with pigs, resulting in concern that human-to-human transmission might have occurred.

Two California children who had not had contact with pigs recently recovered from infections with "unique" swine flu/swine influenza viruses, raising concern about possible human-to-human transmission and putting health authorities on alert, the Centers for Disease Control and Prevention (CDC) reported.

The two cases were in a 10-year-old boy in San Diego County and a 9-year-old girl in neighboring Imperial County, but they are apparently unrelated, the CDC said in an Morbidity and Mortality Weekly Report (MMWR) Dispatch report April 21st. 

A Brief History of the English Language Part 3

The historical development of English is an excellent model of how a grammar naturally develops.  I am trying to capture some of that history in this short series.  Part of the problem of understanding how language works evaporates completely if one can see the beauty in a flow of words, the magic in a few blots of ink.

Part 1 briefly covered the period from the 5th century CE to the 14th century.
Part 2 describes Chaucer's influence on the development of English.
