Sentences with phrase «zebrafish tails»

But a new study shows that zebrafish tails have their own organizing blueprint and are assembled independently of the head and body.
To investigate how zebrafish tails take shape, Thisse's team removed some of the presumed pre-tail cells from early - stage embryos, then transplanted them into the middle of another embryo.
In another set of experiments, Thisse and his colleagues found that three molecules called BMP, Wnt8, and Nodal team up to create zebrafish tails.

The resulting zebrafish grew an extra tail — and only a tail — that extended from its trunk.
Wherever they injected RNA for the trio into the zebrafish embryos, tails popped up, the team reports in the 24 July issue of Nature.
The results indicate that, obtained with a tail - beat frequency of, is a critical speed for the robotic fish, with increases above or below this threshold differentially affecting zebrafish collective response.
Specifically, in [12], it is shown that zebrafish responds differentially to variation in aspect ratio and color in the robotic fish; in [13], it is demonstrated that zebrafish shoals prefer such a robotic fish to an empty compartment; in [14], it is demonstrated that an interactive robot, whose tail - beat frequency responds to fish position, is able to induce preference among single organisms; and in [17], it is shown that the robotic fish is able to simultaneously attract shoals of zebrafish while repelling shoals of mosquitofish that would otherwise display aggressive behavior.

Voot Yin knew a zebrafish could re-grow its severed tail or sliced - off heart tissue, so why couldn't humans?
Specifically, in this series of works it is demonstrated that the behavioral response of zebrafish individuals and small shoals varies as the aspect ratio, color pattern, and tail - beat frequency of a robotic fish is changed.
Specifically, the following predictions are expected to be met: i) fish attraction toward the robotic fish should vary as the visual cues offered by the robotic fish are varied, in agreement with similar observations for zebrafish in [35]--[37]; ii) fish attraction should vary as a function of the robotic fish tail - beat frequency, as suggested in [60] and observed in [20]; and iii) the highest attraction should be reached when both visual and flow cues from the live fish are simultaneously integrated in the robotic fish prototype.

Reduction of one of the lincRNAs, which they called cyrano, caused the zebrafish to have enlarged snouts, small heads and eyes, and short, curly tails, while the zebrafish lacking the lincRNA they called megamind had abnormally shaped heads and enlarged brain ventricles.
The Washington researchers have discovered some of the genes that allow zebrafish to regrow their tail fins, which could one day help humans regrow damaged body parts.
The zebrafish can keep its stripes, and its tail.
If the fish's fin gets bit off by, say, another hungry fish, the zebrafish can grow a new tail in about a week, according to University of Washington researchers.
