According to the Cambridge Dictionary online, the word kosher is applied to food or places where food is sold, prepared or kept in conditions that follow the rules of Jewish law. Informally though it's often used to describe something you can trust.
(But if you want to describe the method of slaughtering animals which conforms to Jewish law - it's not kosher, it's shechita. That just doesn't seem kosher to me.)
(The claimants include Glasgow, Glastonbury, Bewdley, Bollington, Weymouth, Witney, Saffron Walden and St Albans. If any of these places wish to hire me to resolve this dispute, I'd be more than willing.)
According to a study by IronPort, 80% of e-mail spam is sent by Zombie PCs.
(A zombie computer, or zombie, is a computer attached to the Internet that has been compromised by a hacker, computer virus, or trojan horse. Not a computer that wonders around the streets going "Ooh! Aaah!")
For years BMW has been refining its dual-fuel (hydrogen/gasoline) technology. They have now developed the mono-fuel Hydrogen 7, which runs solely on hydrogen.
(According to Argonne National Laboratory it is "one of the lowest emitting combustion engine vehicles that have been manufactured." This is great news! Until you read the Spiegel that is, which says that the hydrogen dispensed at filling stations is generated primarily from petroleum and natural gas. So, the shiny new car puts about as much strain on the environment as a heavy truck with a diesel engine.)
According to figures presented at the 61st International Water Conference, between 1940 and 1990, world water usage increased four-fold.
(This isn't sustainable. Even within the United States, water is being withdrawn faster from underground aquifers than it can be replenished. One aquifer near El Paso, Texas, which serves both the U.S. and Mexico, is expected to run dry by 2020.)
According to the Peace Corp's website, of all the water on earth, 97.5 percent is salt water. Of the remaining 2.5 percent of fresh water, some 70 percent is frozen in the polar ice caps. The other 30 percent is mostly present as soil moisture or lies in underground aquifers.
(This means that less than 1 percent of the world's fresh water (or only about 0.007 percent of all the water on Earth) is readily accessible for direct human use.)
May 1st was declared a workers holiday by the International Working Men's Association (First International) in Paris in 1889.
(It was to commemorate the Haymarket Martyrs of 1886: 8 anarchists who were wrongly accused of throwing a bomb at police. 4 of them; Albert Parsons, August Spies, Adolf Fischer and George Engel were hanged, Louis Lingg committed suicide in prison and in 1893, John Peter Altgeld, pardoned the three surviving men; Samuel Fielden, Oscar Neebe and Michael Schwab. A bit too late though.)
