Judging a Book by Its Genomes [The following is an exact transcript of this podcast.]Thousands of medieval European books survive to this day. Authors and scribes carefully handwrote the works on parchments made of animal skins. But the writers didn’t always bother to sign and date their works. So we had no way of knowing where and when most of the documents are from. Until now. [More] rss.sciam.com |
First drunk driving arrest On this day in 1897, a 25-year-old London taxi driver named George Smith becomes the first person ever arrested for drunk driving after slamming his cab into a building. Smith later pled guilty and was fined 25 shillings.In the United States, the first laws against operating a motor vehicle while under the influence of alcohol went into effect in New York in 1910. In 1936, Dr. Rolla Harger, a professor of biochemistry and toxicology, patented the Drunkometer, a balloon-like device into which people would breathe to determine whether they were inebriated. In 1953, Robert Borkenstein, a former Indiana state police captain and university professor who had collaborated with Harger on the Drunkometer, invented the Breathalyzer. Easier-to-use and more accurate than the Drunkometer, the Breathalyzer was the first practical device and scientific test available to police officers to establish whether someone had too much to drink. A person would blow into the Breathalyzer and it would gauge the proportion of alcohol vapors in the exhaled breath, which reflected the level of alcohol in the blood.Despite the invention of the Breathalyzer and other developments, it was not until the late 1970s and early 1980s that public awareness about the dangers of drinking and driving increased and lawmakers and police officers began to get tougher on offenders. In 1980, a Californian named Candy Lightner founded Mothers Against Drunk Driving, or MADD, after her 13-year-old daughter Cari was killed by a drunk driver while walking home from a school carnival. The driver had three previous drunk-driving convictions and was out on bail from a hit-and-run arrest two days earlier. Lightner and MADD were instrumental in helping to change attitudes about drunk driving and pushed for legislation that increased the penalties for driving under the influence of alcohol and/or drugs. MADD also helped get the minimum drinking age raised in many states. Today, the legal drinking age is 21 everywhere in the United States and convicted drunk drivers face everything from jail time and fines to the loss of their driver's licenses and increased car insurance rates. Some drunk drivers are ordered to have ignition interlock devices installed in their vehicles. These devices require a driver to breath into a sensor attached to the dashboard; the car won't start if the driver's blood alcohol concentration is above a certain limit.Despite the stiff penalties and public awareness campaigns, drunk driving remains a serious problem in the United States. In 2005, 16,885 people died in alcohol-related crashes and almost 1.4 million people were arrested for driving under the influence of alcohol or drugs. history.com |
McKinley dies of infection from gunshot wounds On this day in 1901, U.S. President William McKinley dies after being shot by a deranged anarchist during the Pan-American Exposition in Buffalo, New York.McKinley won his first Congressional seat at the age of 34 and spent 14 years in the House, becoming known as the leading Republican expert on tariffs. After losing his seat in 1890, McKinley served two terms as governor of Ohio. By 1896, he had emerged as the leading Republican candidate for president, aided by the support of the wealthy Ohio industrialist Mark Hanna. That fall, McKinley defeated his Democratic rival, William Jennings Bryan, by the largest popular margin since the Civil War.As president, McKinley became known--controversially--as a protector of big businesses, which enjoyed unprecedented growth during his administration. He advocated the protective tariff as a way of shielding U.S. business and labor from foreign competition, and he successfully argued for using the gold standard of currency.Above all, however, McKinley's presidency was dominated by his foreign policy. In April 1898, he was pushed by Congress and American public opinion to intervene in Cuba's struggle for independence from Spanish colonial rule. In the first American war against a foreign power since 1812, the United States handily defeated Spain in just three months, freeing Cuba--although the island became a U.S. protectorate--and annexing Puerto Rico, Guam and the Philippines. For the first time, the United States had become a colonialist power.America's growing interests in the Pacific led McKinley's administration to greatly increase its involvement in Asian politics. In 1900, McKinley sent thousands of U.S. troops to China to help put down the Boxer Rebellion, aimed at driving out foreigners. His aggressive "Open Door" policy declared U.S. support for an independent China and argued that all nations with commercial interests in China should be able to compete on equal footing.The popular McKinley won a second term by even greater margins over Bryan, who attacked him on his "imperialism" in the Pacific and, domestically, on the growth of illegal monopolies, or trusts. There was little time to see what his second term would bring, however. On September 6, 1901, while standing in a receiving line at the Pan-American Exposition in Buffalo, McKinley was approached by Leon Czolgosz, a Polish-American anarchist carrying a concealed .32 revolver in a handkerchief. Drawing his weapon, Czolgosz shot McKinley twice at close range. One bullet deflected off a suit button, but the other entered his stomach, passed through the kidneys, and lodged in his back. When he was operated on, doctors failed to find the bullet, and gangrene soon spread throughout his body. McKinley died eight days later. Czolgosz was convicted of murder and executed soon after the shooting. history.com |
