Bacterial Toxin Surprises Scientists
... of colicin Ia that are on each side of an artificial
membrane in the channel's open and closed states. They created a family of labeled proteins by changing one specific amino acid in each protein to a cysteine (colicin Ia has no naturally occurring cysteines). They then...
Key to Triplet Repeat Brain Diseases Open Door For New Way To Understand, Treat Genetic Diseases"
...protein. To test that theory, the Duke team made artificial
strings of glutamines,either 20 glutamines, found in normal proteins, or 60 glutamines, foundin the mutant proteins. They then mixed these glutamine strings with brainproteins to see what proteins bound. They found that one brain protein,glyceraldehy...

Tiger Beetles Go Blind At High Speeds
... this knowledge may one day be used for optimizing artificial
tracking systems. "For example, the Mars Rover needs optical sensors to look around Mars, but it also needs to move around the planet. With speed of movement, there's a trade-off. You want to move quickly to explore a large area, but if you move ...
