Scientists find that lightning is good indicator of volcanic activity
03-28-2007 · EurekAlert!Although it's been more than a year since Mount Augustine had its memorable eruption, work continues for University of Alaska Fairbanks researchers. The work of Alaska Volcano Observatory employees from UAF's Geophysical Institute will be appearing in the upcoming issue of the journal Science.

- Scientists link volcanic eruptions that formed North Atlantic Ocean to ancient global warming
04-26-2007 · EurekAlert!
Scientists examining a spike in worldwide ocean temperatures 55 million years ago have linked it to massive volcanic eruptions that pushed Greenland and northwest Europe apart to create the North Atlantic Ocean. Writing in the journal Science, geologists present evidence that this intense volcanic activity occurred at the same time ocean temperatures jumped five to 6 degrees Celsius.

- Study: Sticking to the sand might not be such good, clean fun for beachgoers
08-07-2007 · EurekAlert!
Microbes that result in beach closures and health advisories when detected at unsafe levels in the ocean also have been detected in the sand, according to a study by Stanford University scientists.The study found that sand at beaches all along the California coast contained some level of fecal indicator bacteria. At one popular beach in Monterey, Calif., they found evidence of human waste -- raising doubt about the commonly held belief that some fecal indictor bacteria occur naturally in the sand and are therefore benign.

- Organic is healthier: Kiwis prove that green is good
03-25-2007 · EurekAlert!
Scientists have proven that organically grown kiwifruit contain significantly increased levels of health-promoting polyphenols. They also had a higher overall antioxidant activity, as well as higher levels of ascorbic acid (vitamin C) and important minerals compared with their conventionally grown counterparts.Also, compounds in grapefruit and oranges have been shown to lower blood cholesterol, which could help prevent heart disease.

- Rover Spirit finds evidence of pyroclastic activity on Mars
05-09-2007 · EurekAlert!
A plateau on Mars known as Home Plate was likely the site of explosive volcanic activity, say scientists. And data collected by the rover Spirit also offers further evidence that water was once present at or beneath the planet's surface.

- Scientists identify 36 genes, 100 neuropeptides in honey bee brains
10-25-2006 · EurekAlert!
From humans to honey bees, neuropeptides control brain activity and, hence, our behaviors. Understanding the roles these peptides play in the life of a honey bee will assist researchers in understanding the roles they play in their human counterparts.

- Innovative movies show real-time immune-cell activity within tumors
11-20-2006 · EurekAlert!
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. Immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them. Insights from this new view of the body's on-board defenses against cancer may open the way for improved immunotherapies to treat the disease.

- MU researcher to study volcanism with under-ocean sensors
02-05-2007 · EurekAlert!
Earthquakes and volcanic activity occur when the tectonic plates that make up Earth's surface move apart or converge. While this activity is relatively easy to observe on land, it’s more difficult to observe under the ocean, where most of it occurs. A University of Missouri-Columbia researcher will soon undertake a study to learn more about this process by placing sensors on a mid-ocean ridge called the East Pacific Rise.

- Why small dogs are small
04-05-2007 · EurekAlert!
Soon after humans began domesticating dogs 12,000 to 15,000 years ago, they started breeding small canines. Now, scientists from the University of Utah and seven other institutions have identified a piece of doggy DNA that reduces the activity of a growth gene, ensuring that small breeds stay small.
