A related study, also published in PLOS Genetics, shows that RPM - 1 functions as a part of a novel pathway to control β - catenin activity — this is the first evidence that RPM - 1 works in connection with extracellular signals, such as a family of protein growth factors known as Wnts, and is part of larger signaling networks that regulate development.

The study, which took five years, only looked for planets that orbited rather close to their parent stars (unless the planet is very large the signal from its gravitational hug is too slight to detect with today's technology) so this batch won't produce good candidates for worlds with liquid surface water that might be suited for life.

«I think the main message is that it would be very challenging to detect either a short - term experiment or a long - term deployment of solar radiation management unless it was a pretty large signal,» she said. (scientificamerican.com)
