This knowledge may someday lead to gene therapy strategies forpreventing the skull bones from fusing too early. Smile for the camera. Porcelain crowns and veneers can significantly improveth...Studies Document Ease Of Ecosystem Disruption
...of a keystone species. "Different species interact constantly through such mechanisms aspredation, competition and disease," Sanford said. "Because of that, an impacton a keystone species may cascade through the community and cause a relativelyquick, system-wide impact." The new study report...Porous Silicon Joining Humans To Machines
... could be the key to allowing mechanical devicesto interact with human tissue, according to initial research into thebiocompatibility of the material at De Montfort University, Leicester, UK. Thematerial could lead to "bionic" limb replacements and electronic sensing devicesfor checking body chemistry and po...Mixing Radiation, Minerals, Toxic Waste Could Be Cleanup Boon -- Or Kaboom
... the particle is an oxide, like alumina, gammarays interact not with the chemical but with the oxide, activating it so that itcan catalyze the reaction that breaks down the chemical. Gray says the finding suggests radiation-induced breakdown, or radiolysis, maybe useful for detoxification in both environmenta...Melatonin Shapes Brain Structure In Songbirds
... is to find out just how melatonin andtestosterone interact to encourage efficiency in brain volumes during breedingseason. It is suspected, Bentley said, that it would be "energetically costly"to maintain a large volume of SCN year-round, and the influence of melatoninhelps reduce that cost. The study was su...... insidethe nucleus, where they receive signals and interact with other proteins toinitiate changes in gene activity. The small-molecule hormones, or "ligands,"that regulate most of these nuclear receptors sweep into a cell's nucleus fromfar-flung cells and latch on to their respective receptor, prompting it ......bled shows that this organizing proteinis built to interact with multiple partners," said Wendell Lim, Ph.D., assistantprofessor of molecular and cellular pharmacology at UCSF and senior author onthe paper in Cell. "Requiring dual inputs for activation allows more controlledand precise cellular movements," a...Researchers Discover How The Immune System Shuts Down Faulty T Cells
... Indeed, when theresearchers allowed CD 8 cells to interact with tumor cells that had cast offsome class 1 proteins, the level of cell death among the CD 8 cells doubledwhereas the tumor cells remained increasingly unscathed. "This problem becomes more serious as we get better at developing cancervacc...Concern Unfounded About Damage From Vitamin C

The researchers proposethat both proteins may interact with one another as part of a continuousmolecular pathway--a mutation affecting either protein interrupts the pathway,leading to the same developmental abnormalities.
