Fast animals get plenty of attention for their incredible feats of speed. But what about animals that move at a slower pace?
“We definitely are programmed to think that speed is good,” said James Maclaine, senior curator of fish at the Natural…
Four papers from a team of researchers in Japan have received expressions of concern for overlap in control samples, data, study design and statistical analyses. The publisher of the articles says it has closed its investigation.
