Research out this week helps us understand basics of how neurons communicate
...ich is called a calcium channel. "In this study we removed a specific part of the calcium channel molecule called the 'synaptic protein interaction site' and put this mutant calcium channel back into cells," Dr. Harkins said. "We found that cells with the mutant calcium channel no longer released neurotransm...Brain circuit may permit scientists to eavesdrop on memory formation
...ty likely takes place off-line, when the animal is removed from the direct behavioral experience." Future studies could give insight into the role of sleep in memory consolidation, which has been suggested by many researchers, said Schuman. Studies by other researchers have shown that there is distinctive co...World's top theoretical physicists converge to consider 'future of physics'

According to Corey,... fact, TRPA1 did disappear when the tip links were removed further evidence for a role in that signaling pathway.

...allow for microvascular tissue transfer. Surgeons removed the scarred facial skin, harvested the skin flap from the back, and transferred it to the face. The skin flap was large enough to cover the face completely with extra tissue to create a nose, which otherwise would require a separate surgery.

The researchers will also develop a unique way to attach many thousands of DNA molecules site specifically to a surface to produce a high-throughput device for DNA sequencing by synt...How to use math and a CT scanner to see how trees intercept light
...es yield different CT scan data, the leaves can be removed from the digital model. The resulting skeletal images give more detailed and accurate information than the traditional methods of plant characterization. This information can then be used to estimate the amount of light intercepted by the plant. "Our...Mice thrive despite massive genetic makeover
...coded. Similar-sized regions have previously been removed from the mouse genome, invariably resulting in mice that did not survive, because the missing sequences contained important genes and their deletion had severe consequences for the animal. The other authors of the study include Yiwen Zhu, In...Sandbagging cancer in the bloodstream
... Cancer and Metastasis). While solid tumors can be removed surgically or treated with chemotherapy or radiation, metastatic cells that have already entered the circulation are capable of opening a passageway through blood vessels in order to spread to various organs throughout the body. Once tumor cells lea...Mail-order drugs exposed to extreme heat become less effective

To see if this short-term exposure affected the animal's defense system, the gills were placed in musk-free water with a special red fluorescent dye. Under normal conditions, an efflux transporter will recognize the dye as a foreign subst...Wistar study demonstrates heritability of non-genomic information

Eight of the failing hearts (30 percent) showed high levels of triglycerides a fat storage and transport molecule. Level...Are museum collections of ancient life representative?

Fossils were removed from sandy to silty unconsolidated beds around river and road cuts where fresh earth is exposed and easily accessible, providing excellent coverage of time periods available on the Atlantic Coastal Plain, Barbour Wood said. Lauck Ward, the curator, "...... said. "The embryo was beginning to hatch. When we removed the egg case, we found that the post blastula but pre-hatching embryo at this stage is beginning to transform into a spiral animal. Each such animal had three clockwise spires. After hatching, the spiral organism began to uncoil slightly," Xiao said....Research confirms that vCJD prions can be removed from blood
