The Oldest Life
200,000-Year-Old Patch of Seagrass Is the World's Oldest Living Organism | Popular Science
A patch of Posidonia oceanica, a species of seagrass native to the Mediterranean, has just gotten its DNA sequenced and its age determined--and as it turns out, some parts of this particular patch are up to 200,000 years old. That easily destroys the previous world record of the oldest living organism, a Tasmanian plant believed to be around 43,000 years old. Ha! A youngun!

Grow A Frog Eye Anywhere
My, Your Eyes Are So Electric - ScienceNOW
A decade ago, Michael Levin made a bizarre discovery. Subjected to an electrical pulse, cells in a developing frog gut or tail would form what looked like normal eyes. At the time, the developmental biologist at Tufts University in Medford, Massachusetts, was too busy with other projects to follow up on the discovery. But now he and colleagues have shown that a natural electrical current jump-starts normal eye development in frogs. The discovery comes as a surprise to some biologists, but it may eventually help clarify why certain human eye defects arise and lead to ways to repair damaged or diseased eyes...

For the first time, astronomers have found a planet smack in the middle of the habitable zone of its sunlike star, where temperatures are good for life. “If this planet has a surface, it would have a very nice temperature of some 70° Fahrenheit [21°C],” says William Borucki of NASA’s Ames Research Center here, who is the principal investigator of NASA’s Kepler space telescope. “[It's] another milestone on the journey of discovering Earth’s twin,” adds Ames director Simon “Pete” Worden...

Perfect Insulator Could Eliminate Heating Bills : Discovery News
THE GIST:
- A new material developed by MIT scientists perfectly reflects heat and absorbs none of it.
- This perfect insulator could eliminate heating bills and solve cell phone network overload issues.
- Currently, the material only works under freezing conditions, but a perfect insulator that functions at room temperature is soon expected.

A Real Blast From The Past
Houston (TX) - A NASA satellite has observed a gamma-ray burst from an ancient star that died when the universe was only 630 million years old.
The event, known as GRB 090423, was the most distant cosmic explosion ever recorded.
"The Swift [satellite] was designed to catch these very distant bursts," explained Swift lead scientist Neil Gehrels. "The incredible distance to this burst exceeded our greatest expectations - it was a true blast from the past."

Under-the-Skin Blood Sugar Monitor Boosts Diabetes Control
By Steven Reinberg HealthDay Reporter
Monday, September 8, 2008; 12:00 AMMONDAY, Sept. 8 (HealthDay News) -- A device worn under the skin that measures blood sugar 24/7 can benefit people with type 1 diabetes, a new study shows.
"Continuous glucose monitoring" consists of a disposable blood sugar sensor placed under the skin, worn for a few days and then replaced. The sensor sends data to a transmitter which, in turn, sends it to a receiver worn like a pager. The receiver displays blood glucose levels on a continuous basis.
The device used in the study "monitors blood glucose about every five minutes," said lead researcher Dr. Roy W. Beck, from the Jaeb Center for Health Research in Tampa, Fla. "We evaluated how much benefit, if any, that could have on control of diabetes in both children and adults with type 1 diabetes," he said...

Solar Power Breakthrough
CAMBRIDGE, Massachusetts, August 2, 2008 (ENS) - Within 10 years, homeowners could power their homes in daylight with solar photovoltaic cells, while using excess solar energy to produce hydrogen and oxygen from water to power a household fuel cell. If the new process developed at the Massachusetts Institute of Technology finds acceptance in the marketplace, electricity-by-wire from a central source could be a thing of the past.
'This is the nirvana of what we've been talking about for years,' said MIT's Daniel Nocera, senior author of a paper describing the simple, inexpensive, and efficient process for storing solar energy in the July 31 issue of the journal 'Science.'
'Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon,' Nocera said..."

Pill Pooped
The drugs reproduce many of the biological benefits of exercise, helping cells burn fat better and boosting endurance, said Ronald Evans, a Howard Hughes Medical Institute researcher at the Salk Institute for Biological Studies in California.
One of the pills may some day help people enhance their exercise or training, while the other might be more suited for couch potatoes who need to kick-start themselves, Evans and colleagues reported on Thursday in the journal Cell."

Record Catfish
See the Pictures
posted January 23, 2008
A TWRA Fisheries Biologist recently distributed this e-mail to his counterparts across the state.
"Attached are a couple of photos of a monster blue catfish caught near Greenville, Mississippi by an elderly man who let the fish go after his wife took the pictures. The weight of the catfish is unknown, though some catfish anglers guessed it to be at least 150 pounds. It looks like 200 pounds to me. For sure it would have been a new world record."
