Motor transport in bio-nano systems

... substrate surface. All of these results have been obtained from a combination of analytical calculations and computer simulations. These theories can guide the design of new transport systems by exploring different system architectures in a systematic way before they are actually constructed in the lab. The ...

Natural electrical potential difference affects water transport in clay

... included in these models. The data and parameters obtained by Heister during her research can be used for this purpose. Water transport in the soil is not only caused by hydrostatic pressure but also by differences in salt concentration and electrical potential difference. These processes are called chemica...

New research presents reserve selection using nonlinear species distribution models

... where valuable occurrences of many species can be obtained efficiently. Spatial reserve planning is computationally heavy, if the question is "which 100,000 hectares do I choose from an area of a million hectares," the number of potential reserve structures is huge. Computational reserve planning is further ...

Stegosaur plates and spikes for looks only, researchers say

...an family, which included the stegosaurs. The team obtained fossils from a half-dozen different species of thyreophorans, ranging from the stegosaurs' earliest ancestors - "armored" dinosaurs that lived 200 million years ago - to the first stegosaurs and related ankylosaurs - which had bony plates or scutes a...

New kidney test better elder mortality predictor

...ozen samples. To ensure the accuracy of the values obtained from the frozen samples, the researchers confirmed that a test sample showed no change in values measured over a course of five cycles of freezing and thawing. In future research, Shlipak would like to conduct a clinical trial to determine if cystati...

Lack of coherent cloning policies reflects polarized debate, limited understanding, study says

...t says. Cloned non-human primate embryos have been obtained using SCNT, the report notes, but so far no pregnancy has been reported. Cloned primate embryos have exhibited misaligned chromosomes and the absence of structures necessary for cell division, but some scientists argue that these are technical barri...

Protein prevents detrimental immune effects of bacterial sepsis

...tment, survival increased to 60%. These results, obtained in the lab of Dr. Mauro Perretti, highlight the delicate balance between the "pro-inflammatory/detrimental vs. anti-inflammatory/protective phases" of the immune response. Dr Perretti explained, "For too long, we have ignored anti-inflammatory/count...

Study: 'homemade' gene expression technology unreliable

...we can be confident that a similar result would be obtained if the experiment is repeated elsewhere," Spencer said. Gene chips contain tens of thousands of tiny droplets containing a cell's whole gene sequences that are laid out on a single microscope slide by fast-moving robotic machines. Scientists determin...

...of Cambridge University in England, and colleagues obtained cancer incidence and mortality information for 1,160 relatives of 169 British A-T patients. Female ATM mutation carriers had twice the risk of breast cancer overall compared with the general population. This is equivalent of a lifetime risk of breas...

GroPep announces US FDA approval of biopharmaceutical that uses its cell culture product

Monkeys understand numbers across senses

"The results we obtained provide evidence that monkeys spontaneously detect a correspondence in number between two different sensory modalities, and this tells us that language is not necessary to represent number abstractly," she said. "When we humans apply the word 'three'...

Georgia Tech's AMUSE (Array of Micromachined Ultra Sonic Electrospray) technology has several key advantages over currently available electrospray methods. In AMUSE, the sample aerosolization and protein charging process...
