Multiple genes permit closely related fish species to mix and match their color vision

... types have maximum sensitivities ranging from the red end of the spectrum right through to the ultraviolet--light outside the range of human sensitivity. The researchers showed that in order to tune its color vision, each cichlid species primarily expresses three of the seven cone pigment genes encoded ...

Brain activity related to processing faces is similar in people with, without autism

...genated hemoglobin, the iron-containing pigment in red blood cells. Researchers then can quantify these signals to generate maps of various brain functions. "The brain regions 'specialized' for face processing, the fusiform gyrus, activated almost identically in our autistic study participants and the...

Scientists map one of biology's critical light-sensing structures

...hem to switch between two stable states that sense red and far-red light. The light is actually detected by a specialized pigment that sits within a pocket on the protein. Red and far-red light, says Forest, have the effect of reversibly changing the structure of the pigment in the pocket, which then fli...

Compound from marine bacteria shows potential as multiple myeloma therapy

...ow that causes a plunge in the production of vital red and white blood cells. Although relatively rare, it is the second most common type of blood cancer and accounts for 11,000 deaths annually in the United States.

...gh linear motifs. "One challenge was to eliminate red herrings, which crop up everywhere when you look for very small patterns," Russell says. "The fact that nine of these motifs were already known was a sign we were on the right trail; we then did follow-up experiments in collaboration with Luis Serran...
