Neural stem cells take a step closer to the clinic

...al neural stem cell lines that have been coaxed to thrive in culture for more than a year. The work is an in-depth analysis of global gene expression in human neural stem cells and demonstrates a method for prolonging the shelf life of cultured fetal stem cells, making it possible to generate enough cells t...

Melbourne scientist overturns 30 year calcium dogma

.... "Cancer cells thwart the system by being able to thrive with high concentrations of calcium. Knowledge of the calcium-handling machinery in normal cells should help our understanding of how cancer cells manage this feat," he says. By contrast, brain cells in people with neuro-degenerative diseases such a...

Rapid evolution helps hunted outwit their predators

... fast track to help the hunted survive -- and then thrive to outnumber their predators. This rapid evolution, predicted by Cornell University biologists in computer models and demonstrated with Pac-Man-like creatures and their algae food in laboratory habitats called chemostats, could play an important rol...

Microbes' 'blueprints' promise insights into oceans, more

...strain's slightly different ecological niche--they thrive at different depths in the ocean's surface waters. Chisholm emphasized that "we still don't know the functions of nearly half of these organisms' genes. We're excited about unveiling those functions-particularly for those genes that are unique to the...

Scripps team part of collaboration that reveals first ecological genomic 'blueprints'

...ries surrounding these organisms, such as how they thrive in the nutrient-poor open ocean. For the Palenik-led paper, contributors included Bianca Brahamsha, Eric Allen, and Jay McCarren of Scripps. Others included researchers from Oak Ridge National Laboratory; the Joint Genome Institute; Lawrence Livermo...

Studies probe rapid evolution of Chinese tallow trees

...t taking over native forests. One reason the trees thrive in Texas is that they're ignored by the local insect population. Siemann and Rogers have shown that Texas trees produce lower amounts of chemicals that deter insects, which allows them to grow faster than Asian varieties. "It could be these chemicals...

Scientists: Cloak of human proteins gets HIV into cells

...ers the retrovirus a chance to survive, mutate and thrive in infected people. In general, our hypothesis makes HIV appear nastier than we think it is, and we already think it's a pretty nasty virus." But all is not lost, the Hopkins team says. The new hypothesis, and some quirky observations from the past, ...

... 1 micron." The bacteria are also plentiful. "They thrive in the Virginia Tech duck pond. They live naturally in human intestines but are serious hospital pathogens," she says. "I'm looking at groundwater applications, but there is an area for expansion in terms of controls in hospital environments," she ad...

Rabbit and cow graze together

...such as self-heal, bulbous buttercup and cat's ear thrive in short vegetation, because then they receive enough light to survive. The greatest diversity of plants is found in places where rabbit digging has resulted in bare soil. Therefore, cows ensure that sufficient light reaches the ground, whilst rabbit...

MIT engineers report new approach to tissue engineering

...ences. Further, the resulting tissues continued to thrive when implanted in mice with suppressed immune systems (to eliminate rejection). They expressed human proteins, and integrated with the host's blood-vessel networks. "For me it was very exciting to see that these [stem] cells could move around and sta...

Ecologists have come to rely on midge-species counts for an inexpensive snapshot of stream health. But raw numbers reveal nothing about changes-in-progress that portend environmental per...

Science paper: Overharvesting of Brazil nuts leading to fewer trees

...w almost exclusively in the rainforest and may not thrive in plantations. The nutritive content of the soil in plantations also may be a problem, she said. Some scientists have argued that collection of the nuts doesn't affect the wild trees, which makes some intuitive sense. Even the best harvesters can't...
