University of Oregon researcher finds that on water's surface, nitric acid is not so tough
08-20-2007 · EurekAlert!Nitric acid is a notoriously strong and chemically destructive compound found in water on earth and in our atmosphere. However, a team of researchers have found that its punch is much weaker when it sits on the top of a water surface.

- Marine moss reveals clues to anticancer compound
03-08-2007 · EurekAlert!
An Oregon Health & Science University researcher believes a new gene cluster from a bacterium that protects a moss-like marine invertebrate from predators may be key to engineering cancer-fighting drugs. Dr. Margo Haygood has detailed her research team's discovery of the large gene cluster in a bacterium that secretes a bioactive molecule that not only protects the larvae of a bushy marine bryozoan from predatory fish, but also confounds a variety of cancer cell lines.

- OHSU Cancer Institute researcher identifies protein marker for prostate cancer survival
06-01-2007 · EurekAlert!
Oregon Health & Science University Cancer Institute researchers have identified a protein that is a strong indicator of survival for men with advanced prostate cancer. The C-reactive protein, also known as CRP, is a special type of protein produced by the liver that is elevated in the presence of inflammation.

- OHSU Cancer Institute, VA researchers find way to identify which men need a second biopsy
06-02-2007 · EurekAlert!
A researcher in the Oregon Health & Science University Cancer Institute and Portland Veterans Affairs Medical Center has found a way to identify which men need a second prostate biopsy because they may be harboring life-threatening prostate cancer even though they were given a clean bill of health after their first biopsy.

- 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.

- Life-giving rocks from a depth of 250 km
09-26-2007 · EurekAlert!
If our planet did not have the ability to store oxygen in the deep reaches of its mantle there would probably be no life on its surface. This is the conclusion reached by scientists at the University of Bonn who have subjected the mineral majorite to close laboratory examination. Majorite performs an important function as an oxygen reservoir. Near the Earth's surface the mineral breaks down, releasing oxygen, which then binds with hydrogen from the Earth's interior to form water.

- Case researcher in RNA biology makes waves by challenging current thinking
01-18-2008 · EurekAlert!
In the Jan. 18 issue of Molecular Cell, Case Western Reserve University School of Medicine researcher Kristian E. Baker, Ph.D. challenges molecular biology's established body of evidence and widely-accepted model for nonsense-mediated messenger ribonucleic acid (mRNA) decay. With her collaborator, Ambro van Hoof, Ph.D. of the University of Texas Health Sciences Center, Baker directly tested the "faux 3' UTR" model and proved it could not explain how cells recognize and destroy deviant mRNA.

- Mine runoff continues to provide clues to microbial diversification
03-07-2007 · Oak Ridge National Laboratory (ORNL)
Pink slime at the surface of water trickling through an old mine in California is proving to be a treasure for researchers in their quest to learn more about how bacterial communities exist in nature. A letter published in today's online edition of Nature shows that it is possible to follow what microorganisms are doing in their natural environment by identifying the range of proteins that they produce. The technique, utilized in a microbial community thriving in battery acid-like streams underground at Richmond Mine near Redding, Calif., combines recently developed ways to sequence microbial genes with methods to identify the range of proteins from specific microbial members.

- Drug treats 'water intoxication' faster, more effectively
11-14-2006 · EurekAlert!
Results of the two largest studies on hyponatremia found that the investigational drug tolvaptan treated hyponatremia -- water intoxication -- more effectively than available treatments. These studies, presented by a researcher from Northwestern University, proved that hyponatremia can be treated with an oral drug that has no significant side effects. Hyponatremia is a relatively common electrolyte disorder. It affects a wide spectrum of patients including those with liver problems, heart failure and the elderly. It also may affect marathon runners.

- Folic acid lowers blood arsenic levels, according to Mailman School of Public Health study
10-08-2007 · EurekAlert!
A new study by researchers at Columbia University Mailman School of Public Health finds that folic acid supplements can dramatically lower blood arsenic levels in individuals exposed to arsenic through contaminated drinking water. This toxic element is currently a significant public health problem in at least 70 countries. Chronic arsenic exposure is associated with increased risk for skin, liver and bladder cancers, skin lesions, cardiovascular disease, and other adverse health outcomes.
