Coral Reefs Are Increasingly Vulnerable To Angry Oceans
Size and shape may predict the survival of corals around the world when the weather churns the oceans in the years to come, according to a new model that relies on engineering principles. The increasing violence of storms associated with global climate change, as well as future tsunamis, will have major effects on coral reefs, according to a paper published this week in the international scientific journal Nature. Older Medication May Be More Cost-effective For Some Patients With Sch
A new study analyzing the economic implications of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) concludes that the older (first generation) antipsychotic medication perphenazine was less expensive and no less effective than the newer (second generation) medications used in the trial during initial treatment, suggesting that older antipsychotics still have a role in treating schizophrenia. Catastrophic Tsunami Possible On West Coast
The type of devastating tsunami that struck the southern coast of Asia is entirely possible in the Pacific Northwest of the United States, but might not cause as much loss of life there because of better warning systems, according to experts at Oregon State University. Poaching, Logging, And Outbreaks Of Ebola Threaten Central African Gor
A combination of natural and man-made threats is killing gorillas and chimpanzees in Central Africa, and experts say $30 million is needed for special programs to save some of mankind's closest relatives from disappearing. An action plan from a recent workshop designates 12 areas for emergency programs intended to increase security against illegal hunting, protect great apes and tropical forests from logging, and slow the spread of the Ebola virus in the region. Newts Regrow Hearts: Scientists Reveal Molecular Details Of Regenerati
When a newt loses a limb, the limb regrows. What is more, a newt can also completely repair damage to its heart. Scientists at the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now started to decode the cellular mechanisms in this impressive ability to regenerate and have discovered the remarkable plasticity of newt heart cells. As mammals, and therefore also humans, do not have this ability, the findings could contribute to new cell therapies for patients with damaged organs (Journal of Cell Science, 2006). Immigration Can Lower Prices Of Consumer Products
A forthcoming study challenges the predictions of the perfectly competitive model -- that an increase in demand leads to higher prices. Instead, the study finds that immigration can lower the prices of food, clothing, furniture, and appliances and have a significant moderating effect on inflation. Researchers say that a one percentage point increase in the ratio of immigrants to natives in a city decreases prices by 0.5 percentage points on average. South Asia Slashes Polio Cases By Nearly Half
The three countries on the Asian continent that still have polio are on target to end the disease this year, their health authorities said today. Last year, polio cases in Afghanistan, India, and Pakistan were slashed by 45%. Similar momentum this year should put an end to the transmission of polio in this particularly crowded corner of the world, which has proven a challenge to global eradication efforts. Innovative Tagging Technique May Help Researchers Better Protect Fish
Marine Protected Areas (MPAs) are often hailed as a way to halt serious declines in the abundance of marine species that have been over-fished. But even as nations begin to set aside protected parcels of ocean for marine reserves, the effectiveness of the approach as a fisheries management tool remains unclear. Fish ecologist are now ready to put MPAs to the test with a novel technique for tagging fish. No Trouble Removing Oil From Water
A simple tank-and-siphon system for removing oil from oily water and protecting the environment is about to be launched internationally by an engineering team from the University of New South Wales. Master Regulatory Gene Found That Guides Fate Of Blood-producing Stem
Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow. Knowing the details of this pathway may one day lead to new treatments for such blood diseases as leukemia, as well as a better understanding of how HSCs work in the context of bone-marrow and peripheral-stem-cell transplantation.
