Diverse tropical forests defy metabolic ecology models

...lion trees--and it just did not hold up anywhere," continues Muller-Landau. The CTFS team subsequently tested other metabolic ecology-based predictions relating tree size to growth and mortality against data from 10 CTFS forests, and found that those were not supported either. "The predictions of metabolic e...

Virginia Tech scientists develop process for creating biocompatible fibers

...future opportunities are vast. "Our research group continues to fabricate molecules that self organize and can be electrospun. Potential applications include drug delivery, that is, a carrier and matrix to control the release of drugs." Long's research group is working with Virginia-Maryland Regional College...

Amazon rainforest greens up in the dry season

..., there's a flush of green growth and the greening continues as the dry season progresses." The finding holds true only for the undisturbed portion of the rainforest. Areas where the primary forest has been converted to other uses or disturbed, "brown down" in the dry season, said Huete, a UA professor of soi...

Study outlines genetic differences between potential pandemic influenza strains

...ce on Emerging Infectious Diseases. "As the virus continues its geographic expansion, it is also undergoing genetic diversity expansion," says Rebecca Garten, a researcher on the study. "Back in 2003 we only had one genetically distinct population of H5N1 with the potential to cause a human pandemic, now we ...

Oh, rats! Designer animals reveal possible heart disease genes

...e free of charge at: http://pga.tigr.org/ . TIGR continues to study the panels of designer rat strains, and Lee hopes in the future to knock out specific candidate heart disease genes, directly testing their effects. "With all this information in hand, science is moving from a microscopic to global perspecti...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...s population of Sumatran rhinos, but a small group continues to survive in the "Heart of Borneo," a region covered with vast tracts of rain forest. The survey found evidence of at least 13 rhinos in the interior of the Malaysian state of Sabah in northeast Borneo. It was conducted in 2005 by teams of more th...

Rare Chinese frogs communicate by means of ultrasonic sound

...e conducting a survey of amphibians in China. Feng continues to study frogs and bats to understand how the brain processes sound patterns, especially in sound-cluttered environments in which filtering is required to allow for communication. Feng and colleagues previously reported that males of the species mak...

Scientists develop a way to make the deadliest toxin known even more toxic

...ne response. As the importance of BoNT in medicine continues to expand, we need to find some way to counter these unintended immune responses. Compounds like the ones we discovered, which produced the greatest protease activation ever recorded, may point the way to a potential solution." Other authors of the ...

High resolution 'snapshots' detail dynamics of a cocaine antibody

Despite intensive research, cocaine abuse continues to be a major public health problem, so far eluding efforts at developing an effective therapeutic agent to counter the craving, addiction, and overdose of the drug. To date, no treatment has been approved by the Food and Drug Administration (FDA). ...

Potential heart benefit found in stem cells

..., moral and ethical dilemmas about embryonic cells continues to cloud the field. In research presented today at the American College of Cardiology's 55th Annual Scientific Session, scientists continue to explore mature stem cell sources for potentially significant cardiovascular benefits. ACC.06 is the premi...

Higher carbon dioxide, lack of nitrogen limit plant growth

Estimating the role of terrestrial ecosystems as current and future sinks--or storage places--for excess carbon dioxide hinges on an ability to understand the complex...

For the first time: Longevity modulated without disrupting life-sustaining function

...IGF-1 is the main trigger for childhood growth but continues to exert growth stimulating effects throughout an individual's life. Insulin, which is best know for controlling blood glucose levels, has additional and equally important regulatory functions in the body. In worms, however, the chain of signals is s...

Genes affecting blood pressure change as children become adults

However, if factors ne...

Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

...ing these neural "wire" connections. As the brain continues to develop in adulthood and as myelin is produced in greater and greater quantities, cholesterol levels in the brain increase and eventually promote the production of a toxic protein that attacks the brain. The protein attacks myelin, disrupts messag...

First link of oral bacteria and preterm birth found in human

This study continues Han's research into the suspicion that oral bacteria, once entering the blood, can cause a host of health problems including preterm labor. She confirmed the harm oral bacteria can cause in a mice study in April 2004 when she injected the common ora...

They also found that HIV continues to replicate in the gut mucosa, suppressing immune function in patients being treated with antiretroviral therapy--even when blood samples from the same individuals indicated the treatment was working. Results of the three-year study appear in the Au...

In human melanoma, for example, more than 100 genomic regions exhibit recurring structural changes, not all of which appear to be impo...

A more powerful and efficient engine for rice: the C3-C4 challenge

...hey were warned that unless global rice production continues to increase steadily--despite fewer resources such as land, labor, and capital--millions of people could fall backward into poverty. More than 3 billion people depend on rice as their main food source each day, including most of the world's poor. ...
