A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...of Ocelot Pond, Panama, red-eyed tree frog embryos still in their eggs are about to make a life-or-death decision. The egg clutch, a gelatinous blob clinging to a leaf overhanging the water, has been spied by a bright green parrot snake. In a twinkling, the snake tears a few eggs from the clutch. With tha...

Montreal researchers probe the genetic basis of memory

...t memory storage." Although research on humans is still a distant possibility, the scientists believe their discovery may hold promise in the treatment of a variety of illnesses linked to memory. "The discovery of the role of GCN2 in long-term memory may help us develop targeted drugs designed to enhance ...

Scripps research scientists solve structure of a critical innate immune system protein

...les known as "glycoproteins." "Amazingly there is still this prevalent idea [many scientists have] that glycoproteins don't crystallize," says Wilson. Crystallization of a protein is a crucial initial step in solving its structure via x-ray crystallography, the technique that Wilson and his colleagues emp...

"If you took a single grain of salt from a shaker and dissolved it in a liter jug, the water wouldn't taste very salty," Shi said. "But even that would be more than a millimole, and that's much more acrolein than th...
