Asleep in the deep: Model helps assess ocean-injection strategy for combating greenhouse effect

... bubbles and vent to the atmosphere, defeating the purpose of the whole grand scheme. Even worse, if the liquid-to-gas conversion happens suddenly, the gas can bubble up in a plume and erupt---a potential hazard. Small-scale ocean experiments have been done to investigate how the carbon dioxide (CO2) actua...

Study shows combination of immune substances to be safe

...bination not only proved to be safe ?which was the purpose of the study ?but the researchers found that it stopped disease progression in five of the patients for at least six months. "Our findings were encouraging," Carson says. "They indicate that we can safely administer IL-12 in combination with interf...

Is it Possible to Change Prescribing Habits?

...tem in a US hospital's outpatient clinic. The main purpose of the study was to determine the impact of using computerized alerts to improve the prescribing of medications in the outpatient setting. Studies have shown that 18%?5% of patients might have an ADE in the outpatient environment. This study evaluate...

Deep treasure to be found in Oculina Bank

...d in shallow water, which is much more common. The purpose will be to determine if the deepwater version is a distinct species. This information is significant because the Washington, D.C.-based advocacy group Oceana has petitioned the federal government to include the deepwater form of Oculina under the End...

Researchers offer proof-of-concept for Altered Nuclear Transfer

...proach, but so far it has not been achieved. "The purpose of our study was to provide a scientific basis for the ethical debate," says Whitehead Member Rudolf Jaenisch, lead author on the paper that will be published in the October 16 online edition of the journal Nature. "Our work is the first proof-of-pri...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

Careless reporting on HIV 'could cost lives'

...le of the media in reporting on future trials, the purpose of his team's study is "not to blame the media, but to encourage [researchers] to engage with the media". Bruce Lewenstein, professor of science communication at Cornell University in the United States, told SciDev.Net that the study's conclusion th...

New study to explore cellular circuitry

...allows for high-speed, systemic examination of the purpose of each protein in the yeast cell. Over the last four years, medical center researchers created a library of 6000 clones, or exact copies of the genes of the yeast cell, one clone for each known protein present in the cell. What makes the set of ...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...Frank said. "It's almost freestanding." The exact purpose of the turret and its spire is unknown, but the researchers suspect the function will be as unique as its architecture. They speculate that it may have something to do with the 39-nucleotide leader of the mRNA that the parasite's ribosomes must proce...

Trio of plant genes prevent 'too many mouths'

...eir normal size appears to have an unexpected dual purpose of keeping the plant from wallpapering itself with too many densely clustered stomata. "It's surprising that size and stomata patterning ?both key to plants being able to survive on dry land ?are using the same signaling components," says Jessica Mc...

Public collections of DNA and RNA sequence reach 100 gigabases

Achilles heel of the herpes virus possibly found

...ptor, dubbed B5, is made by most cells for another purpose not yet understood. HSV appears to have evolved a way to latch onto it, and fool the cell into letting the virus in. And since most cells express the gene for the B5 receptor, this may be a reason HSV can get into most kinds of cells. "This may be o...

By creating molecular bridge, scientists change function of a protein

...ou the ability to create protein functions for any purpose you want -- as a catalyst to create new chemicals that might be useful in such things as therapeutics, for example." By way of in-vitro co-evolution, the researchers gradually changed the function of the human estrogen receptor alpha, a nuclear horm...

Protein synthesis can be controlled by light, opening way for new scientific, medical applications

...g as complex as drug delivery, it may well serve a purpose in studying such areas as memory, brain function and even Alzheimer's Disease. "Our technique will enable scientists to conduct experiments aimed at understanding the mechanisms of learning and memory at the molecular and cellular level," said Dore....

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...umber of cancer genes remain to be discovered. The purpose of this study was to locate the likeliest candidates." The study is part of a renewed effort by scientists worldwide to uncover the basic biology of lung cancer, the number one cause of cancer-related deaths in the United States. Non-small cell lung...

A new way to share models of biological systems

... submit, download and reuse the models. That's the purpose of the BioModels database. BioModels provides access to published, peer-reviewed, quantitative models of biochemical and cell-biological systems." Some of these systems are very simple, containing just a few processes or reactions; others contain hu...
