Two thousand stars can see in this ten thousand year periods the planet go in front of the sun. Among these stars, there are a hundred and seventyn that are within a hundred light years. And we were talking about how light needs time to travel, and so that is the region where basically the radio waves have washed over again.
Researchers isolate the protein thought to allow birds to sense magnetic fields, and astronomers pinpoint the stars that could view Earth as an exoplanet.
In this episode:
00:45 Homing in on the molecule that helps birds find their way.
How migratory birds sense magnetic fields is a long standing mystery in sensory biology. Now researchers have isolated a molecule, found within the eyes of these birds, which might act as a compass using quantum mechanics.
Astronomers have catalogued almost 2,000 stars from which the Earth could be detected passing in front of the Sun. The team suggest that these stars would be good targets to search for planets that could harbour life.
We discuss some highlights from the Nature Briefing. This time, the unexpected science kicked up by the Ingenuity helicopter on Mars, and how science is embracing the world of non-fungible tokens (NFTs).
