In speaker technology, the opposite of a tweeter is a woofer, which pumps low-end frequencies while the tweeter amplifies higher-range sounds. On the Web, a tweeter is one who frequents Twitter, using the micro-blogging service to blast 140-character-or-less messages called tweets. So Twitter's opposite is, naturally, Woofer, a new micro-, err, macro-blogging service that requires a minimum of 1,400 characters. http://www.switched.com/2009/08/27/woofer-twitters-1-400-character-opposite/

New Jersey and Oregon are the only U.S. states that currently ban self-service gas stations. The purpose of these laws was to protect consumers and gas station owners from costly, and possibly deadly, accidents. Better education and improved technology, however, have made pumping gas much safer and easier for consumers over the last 50 years. Since the 1970s, self-service gas stations have grown in popularity. The New Jersey law was enacted in 1949 and the Oregon law in 1951. Each statute has stood up to several challenges in those two states. http://www.infoplease.com/askeds/bans-gas-pumping.html

During the last five years, parents hoping to give their kids a competitive edge in the great race to become the brightest (and ostensibly the most elite) did something many child psychologists considered a bit daft: they plopped their kids down in front of a television screen. Now comes the wake-up call as potentially millions of parents who paid as much as $19.99 per "Baby Einstein" DVD didn't get the results they hoped for.
As a Harvard Medical School study indicated, such videos don't promote brain development. Nothing yet, experts say, can replace person-to-baby interaction, leaving the Baby Einstein Co., a subsidiary of Disney, once more backpedaling. More than two years ago, the word "educational" was dropped from the "Baby Einstein" videos, and now, facing a possible lawsuit from the nonprofit Campaign for a Commercial-Free Childhood in Boston, Mass., Baby Einstein Co. will be doling out refunds to the parents of kids who didn't become geniuses. Actually, it won't be that easy to get a refund. Parents will have to show they had confidence in the product, but were dissatisfied with it. And parents can only return up to four DVDs. The campaign for children had complained to the Federal Trade Commission in 2006 that the DVDs made false and deceptive claims about the education value of the series. The FTC decided not to act against the company after it promised to “take appropriate steps to ensure that any future advertising claims of educational and/or developmental benefit for children are adequately substantiated.” In the wake of that action, the campaign noted: "Gone are claims such as the description of Baby Wordsworth as a 'rich and interactive learning experience that … fosters the development of your toddler’s speech and language skills,' or that Numbers Nursery will 'help develop your baby’s understanding of what numbers mean.'” http://dscriber.com/home/553-my-baby-wasnt-an-einstein-after-all-can-i-get-a-refund.html

I have never seen trees with such intense reds and yellows as this year in Toledo. It reminds me that a colleague took a bus trip to New England one fall, and said that the trees in Ohio were more beautiful than what he had seen on his travels.

Sea blobs (dead and living organic matter, called a mucilage) are on the rise.
Enormous sheets of such "mucus" occur naturally throughout the Mediterranean, especially in the Adriatic. But in recent years, as sea temperatures have risen, these sea congregations are exploding in number and size—sometimes stretching over hundreds of kilometers, generally near coastlines. http://news.nationalgeographic.com/news/2009/10/photogalleries/ocean-mucus-sea-pictures/index.html

In 2006, Hormel attempted to register spam as a trademark when used to refer to "services to avoid or suppress unsolicited e-mails" and the "creation and maintenance of computer software; technical consultancy, particularly in combination with network services; (and) providing of expertise, engineering services and technical consulting services (related to junk e-mail)." Hormel argued in an appeal to the Office of Harmonisation for the Internal Market (OHIM), the EU trademark body, that the general public would not immediately recognize the use of the word spam as pertaining to junk e-mail but would instead associate it with "a kind of spicy ham" food product.
