According to a U.S. Geological Survey report, some of the water underneath Maryland is more than a million years old. This is the first such ancient groundwater discovered along the Atlantic coast.
Apparently, water flowed from the land surface into the deep Upper Patapsco aquifer during cooler periods in our earth's history, when glaciers covered much of the northeastern U.S. and sea level was about 125 meters lower than it is today. Today, however, even this deep aquifer, which provides freshwater for the region east of Washington and Baltimore, may not meet future needs.
Worldwide, there aren't many aquifers containing million-year-old groundwater.
The Alberta Basin in Canada, the Nubian aquifer in the Sahara Desert, and the Great Artesian Basin in Australia are other examples.

A Fish With Choppers
In Lake Lou Yeager near Litchfield, Illinois, fish with teeth are being found. A fisherman caught one back on June 7th and now there are claims another was hooked ten days ago. Apparently, these fish have been identified as Pacu, which live in the Amazon basin. Biologists claim that they are not dangerous because they mostly eat nuts, snails, and vegetation. They claim that they only eat other fish if these other food choices are not available. Further, they say that the Pacu cannot survive Illinois winters. They are concerned, however, about the Pacu contaminating other species in the lake.
This Blind Bambi wouldn't be to thrilled about swimming with fish that could take a bite out of me. I hope they find the person responsible for dumping them in the lake.

How Clean is the Water at Your Beach?
The National Resources Defense Council (NRDC) publishes water safety ratings for a number of popular U.S. beaches. Their system awards up to five stars for exceptionally low violation rates and strong testing and safety practices. A dozen beaches got this top rating last year:
Alabama: Gulf Shores Public Beach
Alabama: Gulf State Park Pavilion
California: Bolsa Chica Beach
California: Huntington State Beach, Brookhurst Street
California: Newport Beach, 38th Street, 52nd/53rd Street
Delaware: Dewey Beach
Maryland: Ocean City at Beach 6
Minnesota: Park Point Franklin Park / 13th Street South Beach
Minnesota: Park Point Lafayette Community Club Beach
New Hampshire: Hampton Beach State Park
New Hampshire: Wallis Sands Beach at Wallis Road
Texas: South Padre Island (Town of South Padre Island)
California: Avalon and Doheny State Beach
Illinois: Winnetka Elder Park Beach, North Point Marina and North Beach
Louisiana: Constance, Gulf Breeze, Little Florida, Long and Rutherford
New Jersey: Beachwood Beach West
New York: Woodlawn and Ontario
Ohio: Euclid State Park and Villa Angela State Park
Wisconsin: South Shore Beach
Alabama: Gulf Shores Public Beach
Alabama: Gulf State Park Pavilion
California: Bolsa Chica Beach
California: Huntington State Beach, Brookhurst Street
California: Newport Beach, 38th Street, 52nd/53rd Street
Delaware: Dewey Beach
Maryland: Ocean City at Beach 6
Minnesota: Park Point Franklin Park / 13th Street South Beach
Minnesota: Park Point Lafayette Community Club Beach
New Hampshire: Hampton Beach State Park
New Hampshire: Wallis Sands Beach at Wallis Road
Texas: South Padre Island (Town of South Padre Island)
Conversely, some of the worst recent offenders (lowest rated) include portions of:
California: Avalon and Doheny State Beach
Illinois: Winnetka Elder Park Beach, North Point Marina and North Beach
Louisiana: Constance, Gulf Breeze, Little Florida, Long and Rutherford
New Jersey: Beachwood Beach West
New York: Woodlawn and Ontario

Can Spot Alleviate Stress?
As I'm a dog-lover, a USAToday article about colleges using dogs to help relieve stress in students caught my eye. Apparently, research shows that interaction with pets decreases the level of cortisol — or stress hormone — in people and increases endorphins, known as the happiness hormone. Therefore, if you are feeling stressed, one of the best treatments available may be spending some quality time with your pet.

Poo Power
Talk about a cheap alternative energy source, each day visitors to the Cosmo dog park in Gilbert, Arizona, leave behind about eight cubic yards of dog waste, plastic bottles, bags and other trash. Starting this month, however, that waste will be used to power a light at the park. A team of engineering and technology students at Arizona State University's Polytechnic campus created a "dog waste digester" as part of their iProjects program. Patrons can deposit their dogs’ waste into an underground system, though specially designed openings, where it will be broken down through a process called anaerobic (in the absence of oxygen) digestion. Biogas (a combination of methane, carbon dioxide, water vapor and other gases) is produced as a byproduct and used to generate electricity for the light.

Band-Aid Beware
Penn State researchers may have created the truly "ouchless" bandage. Food scientists have developed a process that spins starch into fine strands that can be combined and formed into inexpensive and environmentally-friendly paper-like mats similar to napkins, tissues and other types of paper products. Starch bandages or medical dressings, however, have an important additional advantage. Whereas current products on the market must at some point be removed (often with some associated pain or discomfort), starch bandages would simply degrade into glucose, a substance the body safely absorbs, eliminating the removal step. They could also be cheaper and have less environmental impact than the cellulose and petroleum-based materials we are familiar with.
