What's up with the mist? In 2004, the Niagara Parks Commission hired consultants to find out if high-rise hotels near Niagara Falls were contributing to the creation of more mist, obscuring the spectacular views. Wind tunnel experiments seemed to confirm the suspicion, a report that circulated in Canadian media. Now University at Buffalo geologists say that the hotels are probably not to blame.
Scientists at the Woods Hole Oceanographic Institution (WHOI) have completed two extensive survey and mapping efforts to better understand why the 2005 New England red tide was so severe and to suggest what might lie ahead.

The 100th anniversary of the 1906 earthquake that devastated San Francisco is a time to reflect on the awesome power of the San Andreas fault. But there's a fault in the Midwest that packs an even greater punch, according to an earthquake expert at the University of Missouri-Rolla.
Tremors within the Earth are usually--but not always--related to the activity of a volcano. Now, such vibrations have been recorded nowhere near a volcano, but at a geologic observatory at the San Andreas Fault.
Behavioral healthcare systems are playing a major role in responding to the needs of the millions of Americans of all ages who experience psychiatric and substance use conditions each year, according to the latest annual survey from the National Association of Psychiatric Health Systems.
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide, according to scientists publishing in this week's issue of the journal Nature.
Virginia A. LiVolsi, MD, Professor of Pathology at the U of Pennsylvania School of Medicine, will be a key presenter at the "Living with Radiation in the Modern World: Commemorating Chernobyl, Remembering Hiroshima / Nagasaki," conference to commemorate the 20th anniversary of the Chernobyl nuclear reactor meltdown.

A team led by physicists at the University of California, San Diego has shown the feasibility of a fast, inexpensive technique to sequence DNA as it passes through tiny pores. The advance brings personalized, genome-based medicine closer to reality.
Just because you don't know much about biology or medicine won't stop you from helping to someday cure diseases like malaria, HIV, or cancer. All you need is a computer and an Internet connection and you can help search for treatments and cures for some of the world's biggest killers.
The Earth's warming temperatures are on track to melt the Greenland and Antarctic ice sheets sooner than previously thought and ultimately lead to a global sea level rise of at least 20 feet, according to new research.
With warming temperatures as the possible underlying cause, scientists wonder what is pushing Greenland's glaciers out to sea as much as 50 percent quicker than before. As a glacier's leading edge calves, openings may be created for ice to stream through, sort of like water through a break in a dike dam.
Notoriously "promiscuous" plants like oaks and dandelions have led some biologists to conclude plants cannot be divided into species the same way animals are. That perception is wrong, say Indiana University Bloomington scientists in this week's Nature.
An international team of physicists has converted three normal atoms into a special new state of matter whose existence was proposed by Russian scientist Vitaly Efimov in 1970.

If subatomic particles had personalities, neutrinos would be the ultimate wallflowers. One of the most basic particles of matter in the universe, they've been around for 14 billion years and permeate every inch of space, but they're so inconceivably tiny that they've been called "almost nothing" and pass straight through things without a bump.
Researchers say partially burning some of the corn stalks, husks and cobs left in corn fields produces products that can be used to improve soil fertility, boost in-soil storage of greenhouse gases and reduce the amount of natural gas used to produce fertilizer.
Today, we almost exclusively tear things down rather than building things up. The thing is, our 'tear it down' manufacturing is highly wasteful and it dramatically limits what we can build. As we get better at working with things at the nano scale, working in the nanosphere promises to turn just about everything around us, including us.
In what ecologists have always thought of as a plant-plant world, scientists have discovered that a lowly caterpillar is slowing down plant recovery at Mt. St. Helens.
