New science investigations, a fresh team ready for Expedition Three on International Space Station
...SS). "This will be our first opportunity to use a sophisticated bioreactor to grow cells in low gravity created as the Station orbits Earth," said Uri. "Cells appear to grow more three-dimensional, like they do in living tissues, when they are cultured in space." Bioreactor cell growth in microgravity permits cul......is case because it allows researchers to carry out sophisticated neurobehavioral tests, comparable to tests used in humans, to see what the effects of alcohol are. Another important aspect concerns the moderate levels of alcohol exposure. There are very few physical problems in these animals, you don't see defic...... Nili Avidan, Tsviya Olender and Miriam Chen, made sophisticated use of the databases created within the framework of the international Human Genome Project. Thanks to this research, scientists from the two Israeli institutions managed to identify the genetic mutations that cause HIBM. These mutations have been ...Gene therapy reduces drinking in "alcoholic" rats
...ists studied the brains of one group of rats using sophisticated imaging techniques. They used a radiotracer, a signal-emitting chemical designed to bind to the D2 receptor protein, then detected the signals in brain images called autoradiographs. The strength of the signals indicated that rats injected with the D...Bacterial communities found to follow water
... most primitive living things, they have developed sophisticated skills for dealing with an environment where water is both scarce and transitory. Desert soils are one of the earthly ecosystems that may have some significance on Mars. If Mars had some water in the past, then these desiccation-resistant environmen...Autumn foliage may affect air quality, climate

The scientists picked Michigan in part because the area's abrupt,heavy frosts are likely to result in high emissions. In contrast,when leaves lose their summer green and wither more gradually, as inthe southeast,...UC Berkeley expert on insect flight receives prestigious MacArthur 'genius' award
...xpertly that they are among the most versatile and sophisticated of all flying animals. The principles he uncovers are even now being applied to the development of tiny flying robots that have potential use in search and rescue, environmental monitoring and remote sensing. "Flies are the most accomplished fliers ......ent voices in the US charge that the anthrax is so sophisticated it can only have been produced with the backing of a government. Their suspicionsare directed at Iraq, which is known to have made anthrax and other bioweapons. But New Scientist can reveal that the bacteria used in the attacks is not a strain that...NSF funds Expresso project, a bioinformatics collaboration

Microarrays (sometimes called DNA chips) are an approach to studying simultaneously the expression of hundreds or thousands of genes in a given organism. The funded project will address all stages ...'Smart bandage' diagnoses danger before infection takes hold

Miller's work is part of the Center for Future Health, a University of Rochester team of researchers working to create a "smart medical home" that will help people keep far better tabs on their personal health with the help of advanced ele...Study: control of chloride channels localized, discovery may boost cystic fibrosis treatment

Huang and colleagues employed a highly sophisticated patch clamp technique, which involves electrical and physical isolation of several CFTR ion channels, to remove tiny pieces of the membrane covering cells that line airway surfaces. Biochemical analyses followed. What was unique about this work was...Discovery of dynamic sub-cellular processes could lead to medical applications
...er surface, where they were absorbed. But by using sophisticated technology to mark the proteins in the Golgi apparatus, the scientists discovered that the proteins from the structure itself were dispersed to unexpected areas of the cell. The article says the finding "suggests that the entire Golgi apparatus is co...Stanford engineer studies neural prosthetics

Such a system could help severely paralyzed people communicate by ``reaching`` toward keys on a virtual keyboard to spell out messages.

As the team grows increasingly sophisticated in understanding the capabilities of this new application of FTMS and interpreting the data they collect, they will progress to multiple strains of bacteria to fully mimic the real world environment under the INEEL site. "Right now we're keeping the ...Scientists identify molecular structure of cancer-related proteins
...s. Researchers recorded the diffraction spots on a sophisticated camera and used a powerful computer to analyze the way in which the atoms scattered the X-rays. The resulting data were used to produce a three-dimensional picture of the proteins. The X-ray crystallography of the proteins was conducted at the Natio...White sharks migrate thousands of miles across the sea, new study finds
