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

... rhino program. "We believe this population may be viable and could recover if their habitat is protected an...ere forests are currently large enough to maintain viable populations. WWF aims to assist Borneo's three nations (Brunei, Indonesia and Malaysia) to conserv...

Cloned stem cells prove identical to fertilized stem cells

...ucleus may have come from, say, a skin cell. For a viable fetus to develop, the egg needs to reprogram the genome of the skin cell, shutting off genes specific for skin tissue and turning on genes needed for embryonic development, genes that are normally dormant in tissue-specific cells. In other words, the...

New influenza vaccine takes weeks to mass produce

... methods researchers have developed a commercially viable method for mass producing effective vaccines against potential pandemic influenza strains in weeks instead of the months required for traditional egg-based vaccines. They report their results today at the 2006 ASM Biodefense Research The next flu pa...

New compound stops brain cell degeneration in Alzheimer's disease

...ver-production of cytokines by activated glia is a viable approach that has the potential to modulate disease onset and progression, the researchers said. Decline of cognitive functions linked to the part of the brain called the hippocampus is a clinical hallmark of Alzheimer's disease. The report demonstr...

Anthrax spores may survive water treatment

...there was no significant decrease in the number of viable spores. "Under those same conditions, one minute exposure could kill 99.99 percent of other waterborne pathogens that do not exist as spores," says Calomiris. Higher concentrations of chlorine were much more effective. At 5mg/L (a concentration...

Environmental metagenomics diagnosing extreme environments, tapping opportunities for clean energy

Human albumin from tobacco plants

...esis, plastidial transformation is an economically viable alternative, as it enables increasing the levels of HSA by between 10 and a 100 times, compared to levels obtained by nuclear transformation. The title of the PhD is: "Production of human serum albumin in tobacco plants by means of plastidial trans...

Computers to save unique type of American red squirrel

...with planting and felling plans to help maintain a viable red squirrel population. Here, the reds' biggest threat is the introduced grey squirrel, which out-competes them for food and transfers a deadly virus. In the US, the new computer model, which mimics population dynamics in response to different th...

Living taste cells produced outside the body

...a prolonged period of time. The establishment of a viable long-term model opens a range of new opportunities to increase scientists' understanding of the sense of taste and how it functions in nutrition, health and disease. "We have an important new tool to help discover molecules that can enhance or block...

Bones from blood: Scientists aim to break new ground on fractures

...tions of the work. The project will seek to find a viable new medical use for the two million units of cord blood banked in Europe, and currently used for transfusions and treating leukaemia. Biologist Dr Paul Genever, who is co-ordinating the project, said: "The mesenchymal stem cells (MSCs) in cord blood...

Predators keep the world green, ecologists find

..."The take-home message is clear: the presence of a viable carnivore guild is fundamental to maintaining biodiversity," the authors wrote. Information collected for the Journal of Ecology report is a five-year update of results published by Terborgh and 10 other scientists in the Nov. 30, 2001, issue of the...

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

...ecisions are made on whether such injections are a viable way to reduce carbon dioxide emission into the atmosphere, Zhang added. Zhang's work was described in a paper in the Oct.1 issue of the journal Environmental Science & Technology. The research was partially supported by the National Science Foun...

Anyway you slice it, tomatoes cut through drought with new gene

... enhanced gene has been inserted in a commercially viable crop, he said. The paper notes that drought conditions throughout the world each year carve out a huge amount of food production. To overcome food shortages, the authors suggest, "it will be necessary to increase the productivity of land al...

Researchers offer proof-of-concept for Altered Nuclear Transfer

...ulting blastocyst has no chance of ever becoming a viable embryo. As a result, a "potential human being" is not destroyed once stem cells have been extracted. Jaenisch--a firm supporter of all forms of human embryonic stem cell research--has shown that technical concerns about this approach can be overcom...

Most embryos produced during IVF do not result in live births
