RECYCLING MAY NOT AMOUNT TO MUCH
Manufacturers have been producing increasingly energy-efficient goods to protect the environment, however people are simply buying more of them -- wiping out green benefits.
An analysis by Dutch academic Jan Kooijman for the United Kingdom packaging industry says while people believe recycling helps curb global warning that is a myth because of the current trend of people living alone.
Each household needs hundreds of essential items -- from toothpaste to clocks -- and each has created greenhouse gases as part of its production process, the BBC reports.
He says by switching from a four-wheel drive car to a normal car for a year, a family could save as much energy as it does by 400 years of recycling bottles.
POP MUSIC CHARTS DATE BACK TO DEPRESSION
After 34 years, Casey Kasem is stepping down from counting down the top selling songs sold in the United States on "American Top 40."
Actually, the idea of the pop music chart originated this week in 1936, the U.S. Census Bureau reports.
Billboard magazine published the list of top songs for the week ending Dec. 30, 1935, which included 78-RPM records by Ozzie Nelson and Tommy Dorsey, whose version of "Santa Claus is Coming to Town" was a hit.
MANY EARTHQUAKES 'NORMAL'
The new year began with a bang -- a 6.1 magnitude earthquake struck Bali hours after an earthquake rocked Mexico City. The next day another earthquake hit Iran.
Despite the recent preponderance of terrestrial trembling, the current level of earthquake activity is normal, David Simpson of the of the Incorporated Research Institutions for Seismology tells Newsweek.
"There are, I think, over 200 earthquakes that have happened over the last 30 days," he says. "This is normal activity."
"(The severity of an earthquake) depends on two things: it depends on how strong the ground-shaking was and how poorly constructed the buildings are."
MEN HAVING LOWER SPERM COUNTS
A study of 7,500 men attending the Aberdeen Fertility Center in Scotland suggests average sperm counts have dropped by 29 percent in 14 years.
The findings, presented at a British Fertility Society meeting in Liverpool, England, are preliminary and researchers are doing further studies to find out if there has been a similar decrease in sperm quality, the BBC reports.
Poor sperm quality can significantly reduce a man's chances of fathering children naturally, according to study leader Dr. Siladitya Bhattacharya.
Until those studies are complete, researchers say it is too early to say whether there has been a decrease in male fertility.
