Episode notes

Most of what humanity has done, let's be honest, in terms of change in the atmosphere, really began with the industrial revolution. Could it be that if you weren't looking all that time ago, there's a narrow band where you could see these kind of changes? We restricted ourselves to technology we have right now, because you can vision anything, right? You could say they have like this huge, i don't know, a thousand meter telescope in space, and they can see a flamingo dancingin on the earth then it's not a problem to find intelligent life,. If you have telescopes like we have, who could find us, and who could thus also see signs of life

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.

09:52 Exoplanet Earth

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.
