Here’s one way that old-fashioned newsprint beats the Internet. Tulane University scientists have discovered a novel bacterial strain, dubbed “TU-103,” that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune newspaper with great success.
TU-103 is the first bacterial strain from nature that produces butanol directly from cellulose, an organic compound.
“Cellulose is found in all green plants, and is the most abundant organic material on earth, and converting it into butanol is the dream of many,” said Harshad Velankar, a postdoctoral fellow in David Mullin’s lab in Tulane’s Department of Cell and Molecular Biology. “In the United States alone, at least 323 million tons of cellulosic materials that could be used to produce butanol are thrown out each year.”
Mullin’s lab first identified TU-103 in animal droppings, cultivated it and developed a method for using it to produce butanol. A patent is pending on the process.
Okay, I admit it. I’m addicted to Twitter. But this infographic made me feel a lot better, because it shows me that I’m not alone. Take a look at Lab42’s findings, all dolled up for you in an infographic that asks 500 Twitter users how they use the service, how they determine who to follow and…
“The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex.”
Women throughout the U.S. won the right to vote when the Tennessee legislature approved the 19th amendment to the U.S. Constitution (the last of 36 states then required to approve it). An amendment for universal suffrage was first introduced in Congress in 1878, and Wyoming had granted suffrage by state law by 1890. This amendment to enfranchise all American women had been introduced annually for 41 years without passage; it had gotten two-thirds of both houses of Congress to approve it just the year before.
