Michigan State scientists identify chemical come-on of sea lamprey
... such as salmon and trout, with a sucking disk and sharp teeth. They suck on body fluids, often scarring and killing host fish. A sea lamprey, in its parasitic life, can kill 40 or more pounds of fish. They are so destructive that under some conditions, only one of seven fish attacked by a sea lamprey will...Transgenic mice mimic cardiac hypertrophy in humans

In mice engineered to lack stat3-beta, experiments showed that more than 120 genes were expressed at higher levels than normal, suggesting the protein normally turns off these ge...Satellites tracking climate changes
